A pair of left and right pedals 60 are provided at the extending ends of the crankshaft 58. A one-way clutch 62 (see FIG. 3) may be provided on the crankshaft 57. The rotational force of the crank 58 may be transmitted to the crankshaft 57 via the one-way clutch 62. In other words, the user's pedaling force, i.e., the force with which the user pedals the pedals 60, may be transmitted to the crankshaft 57 via the one-way clutch 62. When the pair of left and right pedals 60 are pedaled, the crank 58 rotates, and thus the crankshaft 57 rotates. The crankshaft 57 may be provided with a torque sensor 59A (see FIG. 3) that can detect the torque applied to the crankshaft 57. The signal output from the torque sensor 59A, i.e., the signal indicating the torque applied to the crankshaft 57, may be supplied to the ECU 96, which will be described later.

The crankshaft 57 may further include a front sprocket 64a. The rotational force of the crank 58 may be transmitted to the front sprocket 64a via the one-way clutch 62 (see FIG. 3) and the crankshaft 57.

The driving source 16 may be provided near the crankshaft 57. For example, a motor may be used as the driving source 16. The motor may be a brushed motor or a brushless motor. The rotating shaft of the driving source 16 may be connected to a one-way clutch 86 (see FIG. 3). The one-way clutch 86 may be gear-connected to a reduction mechanism 88 (see FIG. 3). The reduction mechanism 88 may be connected to an assist sprocket (not shown) provided in the force combining device 64. The rotational force of the assist sprocket, i.e., the rotational force of the driving source 16 and the rotational force of the crankshaft 57, may be combined by the force combining device 64.

The rear wheel 15r is provided with a rear sprocket 68. A chain 66 is engaged with the front sprocket 64a and the rear sprocket 68. The rotational force combined by the force combiner 64, i.e., the rotational force of the front sprocket 64a, can be transmitted to the rear sprocket 68 via the chain 66. In this way, the rear sprocket 68 can be rotated. The rear sprocket 68 is connected to the rear wheel 15r via a one-way clutch 70 (see FIG. 3). The rear wheel 15r can rotate in response to the rotation of the rear sprocket 68. The rear wheel 15r is provided with a rotation sensor 59B (see FIG. 3) that can detect the rotation of the rear wheel 15r. A signal output from the rotation sensor 59B, i.e., a signal indicating the rotation of the rear wheel 15r, can be supplied to the ECU 96.

The driving source 16 may be configured by an in-wheel motor, i.e., a hub motor. The in-wheel motor is a motor mounted on the axle of the wheel, i.e., the hub. When the driving source 16 is configured by an in-wheel motor, the driving source 16 may be provided, for example, on the hub, i.e., the axle, of the rear wheel 15r. A stator (not shown) of the in-wheel motor may be fixed, for example, between a pair of left and right first sub-frames 54 and between a pair of left and right second sub-frames 56. The rim 21 of the rear wheel 15r may be fixed to a rotor (not shown) of the in-wheel motor via spokes 19. The rear wheel 15r may be rotatably supported via the driving source 16. When the driving source 16 is configured by an in-wheel motor, the rear wheel 15r may be directly rotated by the driving source 16. That is, in such a case, the rotational force of the driving source 16 may be directly transmitted to the rear wheel 15r.

The vehicle body 14 may further be provided with a locking/unlocking unit 72, i.e., a vehicle body locking mechanism, capable of locking and unlocking the vehicle body 14. The locking/unlocking unit 72 may be provided, for example, on the first subframe 54, but is not limited to this. When the locking/unlocking unit 72 is set to a locked state, the locking/unlocking unit 72 may restrict the rotation of the rear wheel 15r. On the other hand, when the locking/unlocking unit 72 is set to an unlocked state, the locking/unlocking unit 72 may allow the rotation of the rear wheel 15r. In this way, the locking/unlocking unit 72 may lock and unlock the vehicle body 14. As described below, the locking/unlocking unit 72 may be controlled by a control unit 98 (see FIG. 5).

The electric vehicle 10 is further provided with a vehicle control device 90. The vehicle control device 90 may be provided, for example, between the pair of left and right second subframes 56, but is not limited to this.

The electric vehicle 10 may further include a main battery 100A. A mobile battery 100B may also be connected to the electric vehicle 10.

The battery holder 104 is provided with a sensor (not shown) , such as a voltage sensor. The sensor 108 is for detecting the state of the main battery 100A. Information obtained by the sensor 108 can be supplied to the ECU 96.

The mobile battery 100B is a smaller battery than the main battery 100A. Therefore, the capacity of the mobile battery 100B is smaller than the capacity of the main battery 100A. In addition, the mass of the mobile battery 100B is smaller than the mass of the main battery 100A. The capacity of the mobile battery 100B is preferably, for example, 2 Ah or more, but is not limited to this.

The mobile battery 100B may be owned by a user, for example. The mobile battery 100B may be used to charge the user's information processing terminal 26 (see FIG. 1), or may be connected to the electric vehicle 10 for use. The side surface of the mobile battery 100B may be provided with a power port 120 (see FIG. 1) capable of outputting power.

The mobile battery 100B does not have to be owned by the user. A shared battery borrowed by the user may be used as the mobile battery 100B. In this case, the battery identification information of the shared battery that the user plans to use may be registered in advance in the sharing system 12. The shared battery may be charged at a battery station (not shown), but is not limited to this. The shared battery may also be charged by a charging device (not shown) owned by the user.

The electric vehicle 10 may further include a battery holder 112. The battery holder 112 may be provided, for example, behind the head pipe 48, but is not limited thereto. The battery holder 112 may detachably store the mobile battery 100B. Since the battery holder 112 is provided on the head pipe 48, the head pipe 48 has a thickness in the front-rear direction and width direction of the vehicle body 14 at the portion where the battery holder 112 is provided. The battery holder 112 may include a storage housing 114. The storage housing 114 is formed integrally with the head pipe 48.

The electric vehicle 10 may be provided with a cable (not shown) that can be connected to the power port 120 of the mobile battery 100B. In this case, the cable may be connected to the power port 120 of the mobile battery 100B.

The battery holder 112 may be provided with a detachment prevention mechanism 122 that prevents the mobile battery 100B from detaching. The detachment prevention mechanism 122 includes a side arm 122a and a lock bar 122b. The side arm 122a may prevent the mobile battery 100B from detaching to the side of the storage housing 114. The lock bar 122b may prevent the mobile battery 100B from detaching to the upper part of the storage housing 114. The detachment prevention mechanism 122 may protrude the lock bar 122b when the mobile battery 100B is inserted into the slit 116, and lock the mobile battery 100B. The detachment prevention mechanism 122 may also release the lock of the mobile battery 100B when, for example, an unlocking operation is performed, but is not limited to this. The unlocking operation may include, for example, input of a password by the user, but is not limited to this. The password may be input, for example, via the operation input unit 43 described later, but is not limited to this. The detachment prevention mechanism 122 may also unlock the mobile battery 100B when, for example, a release signal is received. Such a release signal may be supplied, for example, from the information processing terminal 26.

An information acquisition unit 124 is provided in the battery holder 112. The information acquisition unit 124 is for acquiring information about the mobile battery 100B attached to the battery holder 112. The information about the mobile battery 100B may include battery identification information, which is identification information of the mobile battery 100B.

The information acquisition unit 124 may be provided with various sensors such as a voltage sensor and a current sensor, an input/output interface, a communication module, etc., but is not limited to these. The battery identification information may be indicated by characters, barcodes, etc. on the surface of the mobile battery 100B. In this case, the information acquisition unit 124 may be provided with a reading device, etc. for reading characters, barcodes, etc. The battery identification information may be supplied from the mobile battery 100B to the information acquisition unit 124 by an electrical signal. The information acquired by the information acquisition unit 124 may be supplied to the ECU 96.

A voltage conversion unit 126 is provided in the battery holder 112. The voltage conversion unit 126 is located below the slit 116. The voltage conversion unit 126 may be provided with a DC/DC converter 128. The voltage conversion unit 126 may boost the voltage output from the mobile battery 100B. The voltage conversion unit 126 may further be provided with a function of lowering the voltage. The voltage conversion unit 126 may be located on the power supply path between the mobile battery 100B and the junction box 92 (see FIG. 5 ).

Figure 5 is a block diagram showing a portion of an electric vehicle according to this embodiment. In Figure 5, signal lines are shown using dashed lines. Note that, to avoid complexity, only some of the many signal lines are shown in Figure 5. Also, in Figure 5, wiring such as power lines is shown using solid lines.

As shown in FIG. 5, the mobile control device 90 includes a junction box 92, a PCU (Power Control Unit) 94, and an ECU 96.

The junction box 92 is used to switch the power distribution path. A plurality of wires, i.e., a wire harness, are connected to the junction box 92. The junction box 92 is connected to the main battery 100A via the wires. The junction box 92 is also connected to the voltage conversion unit 126 via the wires. The junction box 92 is also connected to the PCU 94 via the wires.

The ECU 96 includes, for example, a calculation unit 89, a memory unit 91, and an input/output interface (not shown). The calculation unit 89 may be configured, for example, by a CPU processor, i.e., a processing circuit. The calculation unit 89 includes a control unit 98 and an authentication unit 99. The control unit 98 and the authentication unit 99 may be realized by the calculation unit 89 executing a program stored in the memory unit 91. At least a portion of the control unit 98 and the authentication unit 99 may be realized by an integrated circuit such as an ASIC or FPGA. At least a portion of the control unit 98 and the authentication unit 99 may be configured by an electronic circuit including a discrete device.

The storage unit 91 may be composed of a volatile memory (not shown) and a non-volatile memory (not shown). Examples of the volatile memory include RAM, etc. Examples of the non-volatile memory include ROM, flash memory, etc. Data, etc. may be stored in the volatile memory, for example. Programs, tables, maps, etc. may be stored in the non-volatile memory, for example. At least a portion of the storage unit 91 may be provided in a processor, integrated circuit, etc. as described above.

The control unit 98 may control the junction box 92, the PCU 94, etc. The control unit 98 may switch the power distribution path by controlling the junction box 92. The control unit 98 may control the operation of the driving source 16 using the power output from the mobile battery 100B, etc. The control unit 98 may also control the charging of the main battery 100A using the power output from the mobile battery 100B. The control unit 98 may also control the operation of the driving source 16 using both the power output from the mobile battery 100B and the power output from the main battery 100A. The control unit 98 may also control the use of the power output from the mobile battery 100B in preference to the power output from the main battery 100A. Specifically, the power output from the mobile battery 100B may be used preferentially by controlling the voltage conversion unit 126 so that the voltage output from the voltage conversion unit 126 is higher than the voltage output from the main battery 100A.

The control unit 98 can calculate the remaining charge of the main battery 100A, i.e., the remaining battery charge, based on the information supplied from the sensor 108. The main battery 100A may be provided with a function for detecting the remaining charge of the main battery 100A. In this case, information indicating the remaining charge of the main battery 100A may be supplied to the ECU 96. The control unit 98 can appropriately switch the power distribution path based on the remaining charge of the main battery 100A. The control unit 98 can charge the main battery 100A using the power output from the mobile battery 100B. The control unit 98 can transmit information indicating the remaining charge of the main battery 100A to the management machine 30, the management server 28, etc. via the communication device 97 described later. The control unit 98 can also calculate the amount of power supplied from the mobile battery 100B to the main battery 100A. The control unit 98 can transmit information indicating the amount of power supplied from the mobile battery 100B to the main battery 100A to the management machine 30, the management server 28, etc. via the communication device 97.

The control unit 98 can grasp the health of the mobile battery 100B. The control unit 98 can grasp the health of the mobile battery 100B, for example, as follows. That is, the change over time of the output voltage of the mobile battery 100B is acquired using a voltage sensor (not shown). Such a voltage sensor can be provided in the information acquisition unit 124 (see FIG. 4). Furthermore, the change over time of the output current of the mobile battery 100B is acquired using a current sensor (not shown). Such a current sensor can be provided in the information acquisition unit 124 (see FIG. 4). The control unit 98 can calculate the health of the mobile battery 100B based on these changes over time. The control unit 98 can transmit information indicating the health of the mobile battery 100B to the management machine 30, the management server 28, etc. via the communication device 97.

The health of the mobile battery 100B may be determined by other methods. For example, the health of the mobile battery 100B may be determined based on the number of times the mobile battery 100B has been charged. The health of the mobile battery 100B may also be determined based on the number of times the mobile battery 100B has been used. The health of the mobile battery 100B may also be determined based on the period of time that has elapsed since the mobile battery 100B began to be used.

The control unit 98 can determine whether or not the mobile battery 100B has been attached. The control unit 98 can determine whether or not the mobile battery 100B has been attached, for example, in the following manner. That is, when the detachment prevention mechanism 122 locks the mobile battery 100B, a signal indicating that it has been locked is supplied from the detachment prevention mechanism 122 to the control unit 98. The control unit 98 can determine that the mobile battery 100B has been attached to the vehicle body 14 based on this signal.

The control unit 98 can determine whether the mobile battery 100B has been removed. The control unit 98 can determine whether the mobile battery 100B has been removed, for example, in the following manner. That is, when the detachment prevention mechanism 122 releases the lock on the mobile battery 100B, a signal indicating that the lock has been released is supplied from the detachment prevention mechanism 122 to the control unit 98. Based on this signal, the control unit 98 can determine that the mobile battery 100B has been removed from the vehicle body 14.

The PCU 94 can convert the DC power supplied via the junction box 92 into AC power and supply it to the drive source 16. Such AC power is, for example, three-phase AC power, but is not limited to this. If the drive source 16 is a DC motor, DC power can be supplied from the PCU 94 to the drive source 16. The control unit 98 provided in the ECU 96 can adjust the power supplied to the drive source 16 based on a signal supplied from the torque sensor 59A (see FIG. 3) and a signal supplied from the rotation sensor 59B (see FIG. 3).

3, the user's pedaling force may be transmitted in the following order: pedal 60, crank 58, one-way clutch 62, crankshaft 57, force combiner 64, chain 66, rear sprocket 68, one-way clutch 70, and rear wheel 15r. Furthermore, the power of batteries 100A and 100B may be supplied from PCU 94 to drive source 16, thereby rotating drive source 16. The rotational force of drive source 16 may be transmitted in the following order: one-way clutch 86, speed reduction mechanism 88, force combiner 64, chain 66, rear sprocket 68, one-way clutch 70, and rear wheel 15r. The user's pedaling force may be assisted by the driving force of drive source 16, thereby allowing the user to comfortably drive electric vehicle 10.

The electric vehicle 10 may further be provided with a communication device 97. The communication device 97 is connectable to the network 24. The communication device 97 may perform short-range wireless communication. The communication device 97 may also perform communication using a mobile phone network. The control unit 98 may perform communication using the communication device 97. The control unit 98 may communicate with the management server 28, the management machine 30, etc. when the electric vehicle 10 is being used by a user. The control unit 98 may also communicate with the management server 28, the management machine 30, etc. even when the electric vehicle 10 is placed in the station 22, etc.

The electric vehicle 10 may further be equipped with a positioning system (not shown) such as GNSS. The positioning system may periodically observe the current position of the electric vehicle 10. The control unit 98 may transmit information indicating the current position of the electric vehicle 10 to the management server 28, the management machine 30, etc. via the communication device 97.

The electric vehicle 10 may further include an operation input unit 43 (see FIG. 2). The operation input unit 43 may be provided, for example, in the center of the width direction of the handle 42. The operation input unit 43 may include a power button (not shown). The user may turn on/off the power of the electric vehicle 10 by operating the power button. The operation input unit 43 may include a processor, memory, input/output interface, touch panel, communication module, etc. (not shown). The operation input unit 43 may communicate using, for example, a communication module. Specifically, the operation input unit 43 may communicate with the control unit 98. The operation input unit 43 may also communicate with the management server 28, the cultivator 30, etc. The display screen, i.e., the operation screen displayed on the touch panel, may display information supplied from the ECU 96. The display screen may also display information supplied from the management server 28, the cultivator 30, etc. The user may perform various inputs via the operation screen displayed on the touch panel. The operation input unit 43 and the ECU 96 may be connected by a wire. In this case, the operation input unit 43 and the ECU 96 can transmit and receive information via the wire.

When a user wishes to use the electric vehicle 10, the user applies for use via the information processing terminal 26. When the user applies for use, the management server 28 notifies the user of information about the electric vehicle 10 that the user plans to receive. Such information may include the name of the station 22 in which the electric vehicle 10 is located, the management number of the station lock mechanism 38 that locks the electric vehicle 10, the management number of the electric vehicle 10, and the like. The management server 28 supplies registration identification information to the electric vehicle 10 that the user plans to receive. The supply of the registration identification information from the management server 28 to the electric vehicle 10 may be performed via the network 24. The registration identification information is identification information corresponding to the battery identification information of the mobile battery 100B that the user plans to attach to the electric vehicle 10. The supply of the registration identification information from the management server 28 to the electric vehicle 10 may be performed promptly so as to be completed before the user receives the electric vehicle 10. When the registration identification information is provided to the electric vehicle 10 from the management server 28, the authentication unit 99 provided in the electric vehicle 10 stores the registration identification information provided from the management server 28 in the memory unit 91.

A user who has rented the electric vehicle 10 may attach the mobile battery 100B owned by the user to the battery holder 112. When the mobile battery 100B is attached to the battery holder 112, information about the mobile battery 100B is acquired by the information acquisition unit 124. As described above, the information about the mobile battery 100B includes battery identification information, which is identification information of the mobile battery 100B. The information about the mobile battery 100B is supplied to the ECU 96. The authentication unit 99 determines whether the battery identification information supplied from the information acquisition unit 124 matches the registered identification information supplied from the management server 28. Based on the match between the battery identification information supplied from the information acquisition unit 124 and the registered identification information supplied from the management server 28, the authentication unit 99 may authenticate the user. That is, the authentication unit 99 may authenticate the user who attached the mobile battery 100B to the electric vehicle 10 as a user who has the authority to use the electric vehicle 10. At a stage where the user has not been authenticated by the authentication unit 99, the control unit 98 controls the locking/unlocking unit 72 to be in a locked state. When the user has been authenticated by the authentication unit 99, the control unit 98 controls the locking/unlocking unit 72 to be in an unlocked state. In this way, locking/unlocking can be performed based on the battery identification information of the mobile battery 100B attached to the vehicle body 14.

The management unit 158 can manage the mobile battery 100B based on the battery identification information. In other words, the management unit 158 can track, i.e., trace, the mobile battery 100B based on the battery identification information. The management unit 158 can lend the electric vehicle 10 to a user who owns another mobile battery 100B different from the one mobile battery 100B while the one mobile battery 100B remains attached to the vehicle body 14 (see FIG. 1) described later. The user who owns the other mobile battery 100B can remove the one mobile battery 100B that was attached to the vehicle body 14 from the vehicle body 14 and attach the other mobile battery 100B to the vehicle body 14 to use the electric vehicle 10. After using the electric vehicle 10, the user can return the electric vehicle 10 to the station 22 while the other mobile battery 100B that the user attached to the vehicle body 14 remains attached to the vehicle body 14. The management unit 158 accepts the return of the electric vehicle 10 with the other mobile battery 100B still attached to the vehicle body 14. Because the electric vehicle 10 is returned with the other mobile battery 100B attached to the vehicle body 14, the user is no longer in possession of the other mobile battery 100B, but is in possession of one mobile battery 100B.

The reason why the electric vehicle 10 is returned with the mobile battery 100B still attached to the vehicle body 14 is to supply a sufficient amount of power from the mobile battery 100B to the main battery 100A. In other words, it is difficult to charge a large amount of electric charge in a short period of time using the mobile battery 100B. By returning the electric vehicle 10 with the mobile battery 100B still attached to the vehicle body 14, a sufficient charging time is ensured and a sufficient electric charge can be supplied from the mobile battery 100B to the main battery 100A.

As described above, the electric vehicle 10 may be rented out with the mobile battery 100B still attached to the vehicle body 14. The user who rents the electric vehicle 10 may remove the mobile battery 100B attached to the electric vehicle 10. When the mobile battery 100B is removed from the vehicle body 14, the control unit 98 transmits information indicating that the mobile battery 100B has been removed to the management server 28. The storage unit 152 provided in the management server 28 may store information indicating the user who removed the mobile battery 100B from the vehicle body 14 in association with the battery identification information of the mobile battery 100B. Since the information indicating the user who removed the mobile battery 100B from the vehicle body 14 is associated with the battery identification information of the mobile battery 100B, it is possible to identify the user who is holding the mobile battery 100B removed from the vehicle body 14.

As described above, a user who rents an electric vehicle 10 can attach the mobile battery 100B owned by the user to the vehicle body 14. When the mobile battery 100B is attached to the vehicle body 14, information indicating that the mobile battery 100B has been attached is sent to the management server 28. The storage unit 152 provided in the management server 28 stores information indicating the user who attached the mobile battery 100B to the vehicle body 14, linked to the battery identification information of the mobile battery 100B. Since the information indicating the user who attached the mobile battery 100B to the vehicle body 14 is linked to the battery identification information of the mobile battery 100B, it is possible to identify the user who attached the mobile battery 100B.

The management unit 158 may provide a power supply reward, which is a reward for supplying power from the mobile battery 100B to the main battery 100A, to the user who has attached the mobile battery 100B to the electric vehicle 10. The power supply reward may be provided in the form of money or points, etc. The management unit 158 may determine the power supply reward according to, for example, the amount of power supplied from the mobile battery 100B to the main battery 100A.

The management unit 158 may determine the power supply remuneration according to the attachment time, which is the time that the mobile battery 100B is attached to the electric vehicle 10.

The management unit 158 may determine the power supply remuneration based on the attachment time of the mobile battery 100B and the health of the mobile battery 100B. Even if a degraded mobile battery 100B is attached for a long period of time, a sufficient amount of power cannot be supplied from the mobile battery 100B to the main battery 100A. If the power supply remuneration is calculated based on the attachment time of the mobile battery 100B and the health of the mobile battery 100B, a more accurate power supply remuneration can be determined.

The management unit 158 may grant a battery provision reward, which is a reward for providing the mobile battery 100B, to the owner of the mobile battery 100B. The battery provision reward may be granted in the form of money, points, etc.

The management unit 158 may determine the battery provision reward, for example, according to the provision time, which is the time during which the mobile battery 100B was provided. In other words, the management unit 158 may determine the battery provision reward, for example, according to the provision period, which is the period during which the mobile battery 100B was provided. The provision time of the mobile battery 100B is the period between the timing when the mobile battery 100B started to be provided to the sharing system 12 and the timing when the mobile battery 100B is collected by the owner of the mobile battery 100B. For example, if the time between the timing when the mobile battery 100B is attached to the vehicle body 14 by the owner of the mobile battery 100B and the timing when the mobile battery 100B is collected by the owner is two hours, the provision time is two hours. If the time between the timing when the mobile battery 100B is attached to the vehicle body 14 by the owner of the mobile battery 100B and the timing when the mobile battery 100B is collected by the owner is two years, the provision time is two years. In this way, the mobile battery 100B may be collected by the owner of the mobile battery 100B relatively quickly, or may not be collected by the owner of the mobile battery 100B for a long period of time.

The management unit 158 may determine the battery provision reward according to the supply time of the mobile battery 100B and the health of the mobile battery 100B. A degraded mobile battery 100B cannot provide a sufficient amount of power to the main battery 100A. If the battery provision reward is calculated according to the supply time of the mobile battery 100B and the health of the mobile battery 100B, a more accurate battery provision reward can be determined.

The management unit 158 can grasp the current position of the mobile battery 100B. The management unit 158 can grasp the position of the mobile battery 100B based on the position of the electric vehicle 10 to which the mobile battery 100B is attached. Information indicating the current position of the electric vehicle 10 can be acquired by a positioning system (not shown) provided in the electric vehicle 10, as described below. Information indicating the current position of the electric vehicle 10 can be stored in the memory unit 152. The management unit 158 can notify the owner of the mobile battery 100B of current position information, which is information indicating the current position of the mobile battery 100B. The owner of the mobile battery 100B can collect the mobile battery 100B based on such position information.

Figure 6 is a flowchart showing an example of the operation of the sharing system according to this embodiment. An example of authentication processing is shown in Figure 6.

In step S1, the user applies for use of the electric vehicle 10 via the information processing terminal 26. When the application for use is made, the management server 28 notifies the user of information regarding the electric vehicle 10 that the user plans to receive. After this, the process proceeds to step S2.

In step S2, the management server 28 notifies the electric vehicle 10 that the user plans to receive of the registration identification information. The authentication unit 99 stores the registration identification information provided by the management server 28 in the storage unit 91. After this, the process proceeds to step S3.

In step S3, the user attaches the mobile battery 100B to the battery holder 112. When the mobile battery 100B is attached to the battery holder 112, the information acquisition unit 124 acquires battery identification information of the mobile battery 100B. The information acquisition unit 124 supplies the acquired battery identification information to the ECU 96. After this, the process proceeds to step S4.

In step S4, the authentication unit 99 authenticates the user based on whether the battery identification information supplied from the information acquisition unit 124 matches the registered identification information supplied from the management server 28. If the battery identification information matches the registered identification information (YES in step S4), the process proceeds to step S5. On the other hand, if the battery identification information does not match the registered identification information (NO in step S4), the process proceeds to step S6.

In step S5, the authentication unit 99 permits the user to use the electric vehicle 10. Then, the process proceeds to step S7.

In step S6, the authentication unit 99 does not permit the user to use the electric vehicle 10. Then, the process proceeds to step S8.

In step S7, the control unit 98 controls the locking/unlocking unit 72 to be in the unlocked state. When step S7 is completed, the process shown in FIG .

In step S8, the control unit 98 controls the locking/unlocking unit 72 so that the locked state is maintained. When step S8 is completed, the process shown in FIG .

Figure 7 is a flowchart showing an example of the operation of the sharing system according to this embodiment.

In step S11, the management unit 158 lends out the electric vehicle 10 while the one mobile battery 100B remains attached to the vehicle body 14. The electric vehicle 10 is lent out to a user who owns another mobile battery 100B different from the one mobile battery 100B. After this, the process proceeds to step S12.

In step S12, the user who rented the electric vehicle 10 removes one mobile battery 100B attached to the vehicle body 14 of the electric vehicle 10 from the vehicle body 14. After this, the user attaches another mobile battery 100B owned by the user to the vehicle body 14. The user uses the electric vehicle 10 with the other mobile battery 100B attached to the vehicle body 14. After this, the process transitions to step S13.

In step S13, the user returns the electric vehicle 10 to the station 22 with the other mobile battery 100B still attached to the vehicle body 14. The management unit 158 accepts the return of the electric vehicle 10. In this way, the process shown in FIG. 7 is completed.

Figure 8 is a flowchart showing an example of the operation of the sharing system according to this embodiment. Figure 8 shows an example in which the power supply remuneration is determined according to the amount of power supplied from the mobile battery 100B to the main battery 100A.

In step S21, the control unit 98 determines whether or not the mobile battery 100B has been removed from the vehicle body 14. If the mobile battery 100B has been removed from the vehicle body 14 (YES in step S21), the process proceeds to step S22. If the mobile battery 100B has not been removed from the vehicle body 14 (NO in step S21), step S21 is repeated.

In step S22, the control unit 98 calculates the amount of power supplied from the mobile battery 100B to the main battery 100A. The control unit 98 transmits information indicating the amount of power supplied from the mobile battery 100B to the main battery 100A via the communication device 97. The management unit 158 receives this information via the communication unit 154. In this way, the management unit 158 acquires information indicating the amount of power supplied from the mobile battery 100B to the main battery 100A. After this, the process proceeds to step S23.

In step S23, the management unit 158 determines the power supply remuneration based on the amount of power supplied from the mobile battery 100B to the main battery 100A.

In step S24, the management unit 158 grants a power supply reward to the user who attached the mobile battery 100B to the vehicle body 14. The user who attached the mobile battery 100B to the vehicle body 14 is not the user who removed the mobile battery 100B from the vehicle body 14, but the user who previously returned the electric vehicle 10 with the mobile battery 100B still attached to the vehicle body 14. In other words, the user who attached the mobile battery 100B to the vehicle body 14 is not the user who is currently renting the electric vehicle 10, but the user who rented the electric vehicle 10 last time. In this way, the process shown in FIG. 8 is completed.

Figure 9 is a flowchart showing an example of the operation of the sharing system according to this embodiment. Figure 9 shows an example in which the power supply remuneration is determined according to the attachment time, which is the time that the mobile battery 100B is attached to the vehicle body 14.
