In recent years, from the viewpoint of protecting the global environment, devices that generate electricity using renewable energy (solar energy, wind power, geothermal energy, biomass, etc.) with a low environmental load are becoming widespread. In addition, some electric vehicles are equipped with a solar power generation system that generates power using sunlight, which is a type of renewable energy. Hereinafter, the process of charging an in-vehicle power storage device by using the electric power generated outside or inside the vehicle by using renewable energy is also referred to as “CO ₂ free charging”. In addition, the process of charging an in-vehicle power storage device using energy generated outside the vehicle using energy different from renewable energy (oil, coal, natural gas, nuclear power, etc.) is also referred to as "normal external charging".

The inventors of the present application assume the following three use cases for limiting the upper limit storage amount (upper limit SOC) of the on-board power storage device in a power vehicle capable of normal external charging and CO ₂ -free charging. I found that. The first use case is a place where there is a downhill road on the charged route (for example, a home on a hill), assuming that the power storage device is charged with the regenerative power generated on the downhill road after charging. This is a case where the upper limit of the amount of electricity stored is limited when charging with. The second use case is a case in which the upper limit storage amount at the time of normal external charging is usually limited in order to increase the charge amount by CO ₂ free charging (for example, solar charging using sunlight) having a low environmental load. The third use case is a case in which the upper limit storage amount is limited in order to prevent deterioration of the power storage device due to the power storage device being left in a fully charged state.

The above-mentioned Patent Document 1 does not show how to set the upper limit storage amount in a power vehicle capable of normal external charging and CO ₂ -free charging, and charging suitable for the above-mentioned three use cases. Cannot be done.

The present disclosure has been made to solve the above-mentioned problems, and an object thereof is to perform charging suitable for a user's use case in an electric vehicle capable of normal external charging and CO ₂ -free charging. To make it possible.

The charge control device according to the present disclosure is a vehicle charge control device configured to be capable of executing a charge process for charging an in-vehicle power storage device. This charge control device is a control device configured to end charging of the power storage device when the power storage amount of the power storage device reaches the upper limit storage amount during charging, and the vehicle user sets the upper limit storage amount. It is equipped with an interface configured to accept the setting operation of. The charging process includes a process of performing a first charge to charge the power storage device with the power generated outside the vehicle using energy different from the renewable energy, and a process of generating power outside the vehicle or inside the vehicle using the renewable energy. The process of performing a second charge of charging the power storage device with electric power is included. The setting operations that the interface can accept include the first setting operation for setting whether or not to limit the upper limit storage amount during the first charging from the default value, and the default value for the upper limit storage amount during the second charging. The vehicle is parked in a predetermined place with the second setting operation for setting whether or not to limit the storage amount, the upper limit storage amount limit by the first setting operation, and the upper limit storage amount limit by the second setting operation. It includes a third setting operation for setting whether or not to enable it only when.

According to the above charge control device, the user sets whether or not to limit the upper limit storage amount during the first charge (usually external charge) from the default value by performing the first setting operation on the interface. can do. Further, the user can set whether or not to limit the upper limit storage amount during the second charge (CO ₂ free charge) from the default value by performing the second setting operation on the interface. Further, by performing the third setting operation on the interface, the user parks the setting by the first setting operation and the setting by the second setting operation at a predetermined place (for example, a home on a hill). You can set whether to enable it only when it is. As a result, charging suitable for the above-mentioned three use cases can be performed.

For example, the user can limit the upper limit storage amount during the first charging by the first setting operation, while not limiting the upper limit storage amount during the second charging by the second setting operation. With such a setting, it is possible to allow the first charge (usually external charge) to be performed at night and then the second charge (for example, solar power generation using sunlight) to be performed in the daytime. This enables charging suitable for the second use case described above.

Further, the user can limit the upper limit storage amount during the first charging by the first setting operation, and also limit the upper limit storage amount during the second charging by the second setting operation. With such a setting, it is possible to prevent deterioration of the power storage device due to the power storage device being left in a fully charged state. This enables charging suitable for the third use case described above.

Further, the user parks the limit of the upper limit storage amount during the first charging and the limit of the upper limit storage amount during the second charging at a predetermined place (for example, at home on a hill) by the third setting operation. Can only be enabled when you are. With such a setting, for example, when charging at home on a hill, it is possible to limit the upper limit storage amount in advance on the assumption that the regenerative power generated on the downhill road after charging will be charged to the power storage device. This makes it possible to fully charge the power storage device without limiting the upper limit storage amount when charging at other places. This enables charging suitable for the first use case described above.

According to the present disclosure, in a vehicle capable of normal external charging (first charging) and CO ₂ -free charging (second charging), charging suitable for the user's use case can be performed.

The solar panel 316 is installed, for example, on the roof of a house where the power supply facility 30 is provided. The solar panel 316 is connected to the power feeding device 310.

The power supply device 310 is connected to the system power supply 40, the connector 112, and the solar panel 316. The power feeding device 310 is controlled by a control signal from the control device 340. When the power supply device 310 outputs the electric power supplied from the system power supply 40 to the vehicle 10, the power supply device 310 outputs the electric power supplied from the system power supply 40 to the vehicle 10. As a result, the power storage device 100 of the vehicle 10 is charged with the electric power supplied from the system power supply 40.

The grid power source 40 receives power generated by using energy different from renewable energy (oil, coal, natural gas, nuclear power, etc.) (hereinafter, also referred to as “non-CO ₂ free power”) from a power source (not shown). It is configured to be able to supply to the power supply facility 30.

There is.

Further, the power feeding device 310 is configured to be able to output the solar power generated by the solar panel 316 to the vehicle 10. When the solar power generated by the solar panel 316 is output to the vehicle 10, the power supply device 310 converts the solar power (DC) generated by the solar panel 316 into electric power (AC) to be output to the vehicle 10.

The communication device 350 is an interface for communicating with the vehicle 10. The communication device 350 transmits the information transmitted from the control device 340 to the vehicle 10 and transmits the information received from the vehicle 10 to the control device 340.

The control device 340 incorporates a CPU (Central Processing Unit) and a memory (not shown), and controls the power supply device 310 based on the information stored in the memory and the information received from the vehicle 10.

As described above, the vehicle 10 is also configured to be externally rechargeable using non-CO ₂ free power supplied from the system power source 40 outside the vehicle. Hereinafter, the process of externally charging using non-CO ₂ free power generated outside the vehicle is also referred to as "normal external charging" (first charging).

Further, the vehicle 10 is configured to be able to charge the power storage device 100 with the solar electric power (CO ₂ -free electric power) generated by the solar panel 120 provided in the vehicle. Further, in the state where the power supply equipment 30 is connected, the vehicle 10 uses the solar power generated by the solar panel 316 provided in the power supply equipment 30 or the CO ₂ -free power supplied from the grid power supply 40 to store the power storage device 100. Is configured to be rechargeable.

In the following, the process of charging the power storage device 100 of the vehicle 10 using the solar power (CO ₂ free power) generated by the solar panel 120 in the vehicle, or the CO ₂ free power (power supply equipment 30) generated outside the vehicle. The process of externally charging using the solar power generated by the solar panel 316 or the CO ₂ free power supplied from the grid power source 40 is also referred to as "CO ₂ free charging" (second charging).

In the control device 130 according to the present embodiment, when the power storage device 100 is normally being charged by external charging or CO ₂ -free charging, the SOC indicating the power storage amount of the power storage device 100 has reached the upper limit SOC (upper limit storage amount). In this case, it is configured to end the charging of the power storage device 100.

<Setting of upper limit SOC>
The inventors of the present application have described the following three cases as use cases for limiting the upper limit SOC of the power storage device 100 in a vehicle 10 capable of normal external charging (first charging) and CO ₂ free charging (second charging). Found that is expected. The first use case assumes that the power storage device 100 is charged with the regenerative power generated on the downhill road after charging, and a place where the downhill road is on the route after charging (for example, a home on a hill). ), The upper limit SOC is limited. The second use case is a case in which the upper limit SOC at the time of external charging is usually limited in order to increase the amount of charge by solar charging (CO ₂ free charging) having a low environmental load. The third use case is a case in which the upper limit SOC is limited in order to prevent deterioration of the power storage device 100 due to the power storage device 100 being left in a fully charged state.

The HMI device 150 according to the present embodiment is configured to allow the user of the vehicle 10 to accept a setting operation for setting the upper limit SOC in order to enable charging suitable for the above-mentioned use case.

The setting operations that the HMI device 150 can accept include the first setting operation for setting whether or not to limit the upper limit SOC during normal external charging from the default value (for example, 100%), and CO ₂ free charging. The vehicle 10 sets the second setting operation for setting whether or not to limit the upper limit SOC of the above to the default value, the upper limit SOC limitation by the first setting operation, and the upper limit SOC limitation by the second setting operation. It includes a third setting operation for setting whether or not to enable it only when parked (for example, at home on a hill). As described above, the "predetermined place" is assumed to be a place where there is a downhill road on the route after charging (for example, a home on a hill). In the following, an example in which "home (on a hill)" is registered as a predetermined place will be described, but the predetermined place may be a place other than the home.

FIG. 2 is a diagram showing an example of an upper limit SOC setting screen displayed on the HMI device 150. The user can set the upper limit SOC at the time of charging on this screen.

By performing a touch operation on the setting screen shown in FIG. 2, the user can select whether to set the upper limit SOC limit at the time of normal external charging to "On" or "Off". This operation is the above-mentioned first setting operation. When the limit of the upper limit SOC during normal external charging is set to "Off", the upper limit SOC during normal external charging is not limited and is set to the default value Sd (100% in the example shown in FIG. 2). On the other hand, when the limit of the upper limit SOC at the time of normal external charging is set to "On", the upper limit SOC at the time of normal external charging is set to the limit value Slim smaller than the default value Sd. FIG. 2 shows an example in which the upper limit SOC limit at the time of normal external charging is set to "On" and the limit value Slim is set to 60%. The value of the limit value Slim can be arbitrarily changed by the user.

Normally, when the upper limit SOC limit for external charging is set to "On", the user can set the upper limit SOC limit for CO ₂ free charging by performing a touch operation on the setting screen shown in FIG. It is possible to select whether to set "On" or "Off". This operation is the above-mentioned second setting operation. When the upper limit SOC limit during CO ₂ -free charging is set to "Off", the upper limit SOC during CO ₂ -free charging is not limited and is set to the default value Sd. On the other hand, if the upper limit SOC limit during CO ₂ -free charging is set to "On", the upper limit SOC can be set to the limit value Slim not only during normal external charging but also during CO ₂ -free charging.

Further, the user can select whether to set the setting to "On" or "Off" only at home by performing a touch operation on the setting screen shown in FIG. 2. This operation is the above-mentioned third setting operation. When the home-only setting is set to "Off", the setting by the first setting operation (normally the upper limit SOC limit at the time of external charging) and the setting by the second setting operation (the upper limit SOC limit at the time of CO ₂ free charging) are set to the vehicle. It can be valid regardless of whether or not 10 is parked at home. On the other hand, if the setting only at home is set to "On", the setting by the first setting operation (normally the upper limit SOC limit at the time of external charging) and the setting by the second setting operation (the upper limit SOC limit at the time of CO ₂ free charging) are set. , Can only be valid when the vehicle 10 is parked at home on a hill. Note that FIG. 2 shows an example in which the setting is set to "Off" only at home.

The contents set on the setting screen shown in FIG. 2 are stored in the memory of the control device 130.
FIG. 3 is a flowchart showing an example of a processing procedure executed by the control device 130. This flowchart is repeatedly executed every time a predetermined condition is satisfied (for example, every predetermined cycle).

The control device 130 determines whether or not the power storage device 100 is being charged by normal external charging or CO ₂ -free charging (step S10). When the power storage device 100 is not normally being charged by external charging or CO ₂ -free charging (NO in step S10), the control device 130 skips the subsequent processing and shifts the processing to the return.

When the power storage device 100 is being charged by normal external charging or CO ₂ free charging (YES in step S10), the control device 130 determines whether or not the setting is "On" (with setting) only at home (with setting). Step S12). If the home-only setting is not "On" (NO in step S12), the control device 130 shifts the process to step S16.

When the home-only setting is "On" (YES in step S12), the control device 130 determines whether or not the current position of the vehicle 10 calculated by the GPS module 160 is a pre-registered home (YES). Step S14). When the current position of the vehicle 10 is home (YES in step S14), the control device 130 shifts the process to step S16. If the current position of the vehicle 10 is not at home (NO in step S14), the control device 130 shifts the process to step S24.

In step S16, the control device 130 determines whether or not the external charging is normally in progress (step S16).

When the normal external charging is in progress (YES in step S16), the control device 130 determines whether or not the setting of the upper limit SOC limit at the time of normal external charging is “On” (limited) (step S18). When the setting of the upper limit SOC limit at the time of normal external charging is "On" (YES in step S18), the control device 130 sets the upper limit SOC to the limit value Slim (for example, 60%) (step S20). When the setting of the upper limit SOC limit at the time of normal external charging is not "On" (NO in step S18), the control device 130 sets the upper limit SOC to the default value Sd (for example, 100%) (step S24).

Normally, when external charging is not in progress (NO in step S16), that is, when CO ₂ -free charging is in progress, the control device 130 sets the upper limit SOC limit for CO ₂ -free charging to "On" (limited). (Step S22). When the setting of the upper limit SOC limit at the time of CO ₂ free charging is "On" (YES in step S22), the control device 130 sets the upper limit SOC to the limit value Slim (step S20). When the setting of the upper limit SOC limit at the time of CO ₂ free charging is not "On" (NO in step S22), the control device 130 sets the upper limit SOC to the default value Sd (step S24).

Next, the control device 130 determines whether or not the SOC of the power storage device 100 has reached the upper limit SOC set in step S20 or step S24 (step S26). When the SOC of the power storage device 100 has not reached the upper limit SOC (NO in step S26), the control device 130 continues charging (step S28). On the other hand, when the SOC of the power storage device 100 reaches the upper limit SOC (YES in step S26), the control device 130 ends charging (step S30).

In FIG. 4, the setting of the upper limit SOC limit at the time of normal external charging is "On", the setting of the upper limit SOC limit at the time of CO ₂ free charging is "Off", and the setting of only the home is "Off". It is a figure which shows an example of the change of SOC of a power storage device 100 when the power storage device 100 is charged in the state.

In the example shown in FIG. 4, the SOC increases with the start of normal external charging at 11:00 PM, and the SOC reaches the limit value Slim at 6:00 AM the next day. Since the setting of the upper limit SOC limit at the time of normal external charging is "On", the normal external charging is stopped at 6:00 AM when the SOC reaches the limit value Slim.

After that, when the sun shines and solar power generation starts, the setting of the upper limit SOC limit at the time of CO ₂ free charging is "Off" and the SOC is not limited to the limit value Slim, so solar charging at 9:00 AM ( CO ₂ free charging) is started and SOC starts to increase again. Then, the solar charging is stopped at 7:00 PM when the SOC reaches the default value Sd.

In this way, the user normally limits the upper limit SOC during external charging to the limit value Slim, and sets the upper limit SOC during solar charging (CO ₂ free charging) to the default value Sd without limiting to the limit value Slim. By performing this, it is possible to perform solar charging during the daytime when solar power generation is possible after performing external charging normally during the nighttime time when solar power generation is not possible.

As described above, the electric power system 1 according to the present embodiment can charge the power storage device 100 suitable for the user's use case in the vehicle 10 which is normally capable of external charging and CO ₂ -free charging. Specifically, the power system 1 is configured to end charging of the power storage device 100 when the SOC (storage amount) of the power storage device 100 reaches the upper limit SOC (upper limit storage amount) while the power storage device 100 is being charged. A charge control device including the control device 130 and the HMI device 150 configured to accept the first setting operation, the second setting operation, and the third setting operation for the user of the vehicle 10 to set the upper limit SOC. include.

By performing the first setting operation on the HMI device 150, the user can set whether or not to limit the upper limit SOC during normal external charging from the default value Sd. Further, the user can set whether or not to limit the upper limit SOC during CO ₂ -free charging from the default value Sd by performing the second setting operation for the HMI device 150. Further, by performing the third setting operation on the HMI device 150, the user parks the setting by the first setting operation and the setting by the second setting operation at a predetermined place (for example, a home on a hill). It is possible to set whether or not to enable it only when it is.

The user can limit the upper limit SOC during normal external charging by the first setting operation, while not limiting the upper limit SOC during CO ₂ -free charging by the second setting operation. With such a setting, it is possible to allow solar charging (CO ₂ free charging) in the daytime after normal external charging at night. This enables charging suitable for the second use case described above.

Further, the user can limit the upper limit SOC during normal external charging by the first setting operation, and also limit the upper limit SOC during CO ₂ -free charging by the second setting operation. With such a setting, it is possible to prevent deterioration of the power storage device 100 due to the power storage device 100 being left in a fully charged state. This enables charging suitable for the third use case described above.

Further, the user parks the upper limit SOC limit during normal external charging and the upper limit SOC limit during CO ₂ -free charging in a predetermined place (for example, at home on a hill) by the third setting operation. Can only be enabled when. With such a setting, for example, when charging at home on a hill, the upper limit SOC can be limited in advance on the assumption that the regenerative power generated on the downhill road after charging is charged to the power storage device 100. This makes it possible to fully charge the power storage device 100 without limiting the upper limit SOC when charging at other places. This enables charging suitable for the first use case described above.

<Modification 1>

However, if it is not possible to distinguish whether the power supplied from the grid power supply 40 to the power supply equipment 30 is non-CO ₂ -free power or CO ₂ -free power, for example, the power is supplied from the grid power supply 40 to the power supply equipment 30. All the power may be treated as non-CO ₂ free power.

<Modification 2>
In the above-described embodiment, the interface (HMI device 150) provided in the vehicle 10 accepts the setting operations (first setting operation, second setting operation, third setting operation) for setting the upper limit SOC. showed that.

However, the setting operation for setting the upper limit SOC may be accepted by an interface outside the vehicle (for example, the user terminal 20) configured to be able to communicate with the vehicle 10.
