Description

The present invention relates to a heat storage management system.

Conventionally, a heat storage management system for a mobile body such as an electric vehicle (EV) uses a battery, which is a driving power source, as a heat storage unit while controlling the temperature of the battery (see Patent Document 1 below). The heat stored in the battery is used for air conditioning, etc. by exchanging heat with a refrigerant in a heat pump (refrigerant circuit) via a heat medium circuit for controlling the battery temperature.

JP 2014-37180 A

The surrounding environment of a heat storage management system mounted on a moving object such as an electric vehicle changes as the vehicle moves. This change in the surrounding environment can sometimes be advantageous for a system that stores heat. For example, when a vehicle passes through a tunnel, the outside air temperature is often higher inside the tunnel than outside, and if the heat from this increase in outside air temperature can be taken in and stored in the system, this will be advantageous for the system's heat management. Also, when an electric vehicle travels uphill, the load on the drive motor increases and the amount of exhaust heat increases, but if this exhaust heat can be taken in and stored in the system, this will be advantageous for the system's heat management.

However, conventional heat storage management systems do not take special measures to deal with such changes in the surrounding environment, and there is a problem in that they miss opportunities to increase the amount of heat storage that accompanies changes in the surrounding environment.

In addition, conventional heat storage management systems use a battery, which is the driving power source, as the heat storage unit, and prioritize managing the battery temperature at an appropriate temperature. Therefore, even if there is an opportunity to increase the amount of stored heat due to changes in the surrounding environment as described above, there is a problem that there is a limit to how much heat can be increased at the prioritized battery management temperature.

The objective of the present invention is to address these problems. In other words, the objective of the present invention is to prevent a heat storage management system to be installed in a mobile body from missing an opportunity to increase the amount of heat stored due to changes in the surrounding environment.

In order to solve such problems, the present invention has the following configuration.
A heat storage management system that is mounted on a moving body and includes a heat medium circuit through which a heat medium circulates, a heat storage section in which heat is stored via the heat medium, a heat generating section that dissipates heat to the heat medium, and a control device that controls the amount of heat stored in the heat storage section, wherein the control device controls to increase the amount of heat stored in the heat storage section based on environmental information that is favorable for heat storage when storing heat in the heat storage section.

The heat storage management system of the present invention, which has these characteristics, detects environmental information that is favorable for heat storage and controls the amount of stored heat to increase, so that it does not miss opportunities to increase the amount of stored heat that occurs due to changes in the surrounding environment, but increases the amount of stored heat and makes effective use of the stored heat.

Embodiments of the present invention will be described below with reference to the drawings. In the following description, the same reference numerals in different drawings indicate parts with the same function, and duplicate descriptions in each drawing will be omitted as appropriate.

As shown in FIG. 1, the heat storage management system 1 according to an embodiment of the present invention is a system mounted on a moving object such as a vehicle or ship, and includes a heat medium circuit 2 through which a heat medium circulates, a heat storage section 3 in which heat is stored via the heat medium, and a heat generating section 4 that dissipates heat to the heat medium.

The heat medium circuit 2 includes pumps P (P1, P2, P3) that circulate the heat medium, and switching valves V (V1, V2, V3) that switch the flow path of the heat medium circuit 2 according to various control modes. The heat medium circuit 2 also includes heat exchange units T (T1, T2, T3, T4, T5, T6) for exchanging heat with the heat medium.

In the illustrated example, the heat exchanger T1 is for the heat medium to exchange heat with the heat storage section 3, and the heat exchanger T2 is for the heat medium to exchange heat with the heat generating section 4. The heat exchanger T3 is provided in the indoor air conditioner 5 for the heat medium to exchange heat with the indoor air, and the heat exchanger T4 is for the heat medium to exchange heat with the outside air blown by the fan 6 (radiator).

Heat exchange unit T5 and heat exchange unit T6 are refrigerant-heat medium heat exchangers in which the refrigerant and heat medium in the heat pump type refrigerant circuit 10 exchange heat. Heat exchange unit T5 functions as a radiator in the refrigerant circuit 10, and the heat of the refrigerant is released to the heat medium. Heat exchange unit T6 functions as a heat absorber in the refrigerant circuit 10, and the heat of the heat medium is absorbed by the refrigerant. The refrigerant circuit 10 is equipped with a compressor 11 that compresses the refrigerant and sends it to the heat exchange unit T5, and a pressure reducing device (such as an expansion valve) 12 that reduces the pressure of the compressed refrigerant and sends it to the heat exchange unit T6.

In the heat storage management system 1, the heat storage unit 3 is, for example, a battery for driving an electric vehicle (EV). During heat storage, when heat is released from the heat medium to the heat storage unit 3, the heat storage unit 3 is heated, and during heat storage utilization, when the heat medium absorbs the heat stored in the heat storage unit 3, the heat storage unit 3 is cooled. As a result, the battery as the heat storage unit 3 is adjusted to a predetermined temperature by appropriately repeating heat storage and heat utilization.

In the heat storage management system 1, the heat generating unit 4 is, for example, a motor, inverter, or PCU (Power Control Unit) that generates heat when driven in an electric vehicle (EV). The refrigerant circuit 10 described above functions as a heat generating unit in that it has the function of dissipating heat to the heat medium circulating in the heat medium circuit 2.

The heat storage management system 1 includes a control device 20 that controls the amount of heat stored in the heat storage unit 3, as shown in FIG. 2(a). The control device 20 controls the amount of heat stored by changing the control mode based on input data such as environmental information that changes as the mobile object moves, and the control targets include the switching valve V, the compressor 11 and pressure reducing device 12 of the refrigerant circuit 10, the pump P, the indoor air conditioner 5, and the fan 6.

The control mode by the control device 20 is a switching control among the heat storage mode, the heat storage utilization mode, and the heat storage increase mode, as shown in FIG. 2(b). Here, the transition from the heat storage mode to the heat storage increase mode is referred to as the heat storage amount increase control performed by the control device 20.

Figures 3 to 5 show the switching state of the heat medium circuit 2 in the heat storage mode, heat storage utilization mode, and heat storage increase mode when storing warm heat. In the figures, the thick black lines with arrows indicate the heat medium flow paths through which the heated heat medium flows in the direction of the arrow, the thick grey lines with arrows indicate the heat medium flow paths through which the cooled heat medium flows in the direction of the arrow, and the thick double lines with arrows indicate the refrigerant flow paths of the refrigerant circuit 10. Thin dashed lines indicate the heat medium flow paths when not in use. In the illustrated switching valves V2 and V3, the white areas indicate the open state of the valves, and the black areas indicate the closed state of the valves.

In the heat storage mode, as shown in FIG. 3, the heat medium circuit 2 becomes independent circuits of the first heat medium circuit 21, the second heat medium circuit 22, and the third heat medium circuit 23 by switching the switching valve V (V1 to V3).

The first heat medium circuit 21 forms a circulation flow path in which the heat medium returns to the pump P1 via the pump P1, the heat exchanger T1, the heat exchanger T2, the switching valve V2, and the switching valve V1. In the first heat medium circuit 21, the heat medium that has absorbed heat from the heat generating unit 4 in the heat exchanger T2 flows to the heat exchanger T1, and the heat absorbed in the heat medium is dissipated to the heat storage unit 3 in the heat exchanger T1.

The second heat medium circuit 22 forms a circulation flow path in which the heat medium returns to the pump P2 via the pump P2, the heat exchanger T5, the heat exchanger T3, and the switching valve V1. In the second heat medium circuit 22, the heat medium that has absorbed the heat of the refrigerant in the heat exchanger T5 flows to the heat exchanger T3, and the heat absorbed in the heat medium is released to the air in the indoor air conditioner 5 in the heat exchanger T3.

The third heat medium circuit 23 forms a circulation flow path in which the heat medium returns to the pump P3 via the pump P3, the heat exchanger T6, the switching valve V3, and the heat exchanger T4. In the third heat medium circuit 23, the heat medium that has had heat absorbed by the refrigerant in the heat exchanger T6 flows to the heat exchanger T4, where it absorbs heat from the outside air.

In the heat storage mode shown in FIG. 3, the heat generated in the heat generating section 4 is stored in the heat storage section 3 by the circulation of the heat medium in the first heat medium circuit 21, the heat dissipated from the refrigerant in the refrigerant circuit 10 by the circulation of the heat medium in the second heat medium circuit 22, the indoor air conditioner 5 performs heating operation, and the heat medium in the third heat medium circuit 23 is circulated so that the heat of the outside air is absorbed by the refrigerant in the refrigerant circuit 10.

In the heat storage utilization mode, as shown in FIG. 4, by switching the switching valve V (V1 to V3), the heat medium circuit 2 becomes an independent circuit consisting of the second heat medium circuit 22 and the fourth heat medium circuit 24 described above.

The fourth heat medium circuit 24 forms a circulation flow path in which the heat medium returns to the pump P1 via the pump P1, the heat exchanger T1, the heat exchanger T2, the switching valve V2, the pump P3, the heat exchanger T6, the switching valve V3, and the switching valve V1. In the fourth heat medium circuit 24, the heat stored in the heat storage unit 3 is taken into the heat medium in the heat exchanger T1, and the heat generated in the heat generating unit 4 is taken into the heat medium in the heat exchanger T2, and the heat taken into the heat medium is absorbed by the refrigerant in the heat exchanger T6. In the heat storage utilization mode shown in FIG. 4, the heat stored in the heat storage unit 3 and the heat generated in the heat generating unit 4 are absorbed by the refrigerant via the heat medium, and the indoor air conditioner 5 is operated in a heating mode by the heat dissipation of the refrigerant circuit 10.

In the heat storage increase mode, as shown in FIG. 5, by switching the switching valve V (V1 to V3), the heat medium circuit 2 becomes an independent circuit of the third heat medium circuit 23 and the fifth heat medium circuit 25 described above.

The fifth heat medium circuit 25 forms a circulation flow path in which the heat medium returns to the pump P1 via the pump P1, the heat exchanger T1, the heat exchanger T2, the switching valve V2, the switching valve V1, the pump P2, the heat exchanger T5, the heat exchanger T3, and the switching valve V1. In the fifth heat medium circuit 25, the heat generated in the heat generating unit 4 is taken into the heat medium in the heat exchanger T2, the heat released by the refrigerant circuit 10 is taken into the heat medium in the heat exchanger T5, and the remaining heat used for heating the indoor air conditioner 5 in the heat exchanger T3 is stored in the heat storage unit 3 in the heat exchanger T1. Compared to the heat storage mode shown in FIG. 3, the heat storage increase mode shown in FIG. 5 increases the amount of heat storage compared to the heat storage mode by additionally storing the heat released by the refrigerant circuit 10 that was not used for heating in the heat storage unit 3.

Figure 1 shows the circuit configuration when storing hot heat, but a heat storage management system 1 equipped with a circuit as shown in Figure 6 can store cold heat in the heat storage section 3. In this case, the heat medium circuit 2 is equipped with a pump P (P10, P11) that circulates the heat medium, and also with a switching valve V (V10, V11) that switches the flow path of the heat medium circuit 2 according to various control modes. The heat medium circuit 2 also has a heat exchange section T (T10, T11, T12, T13, T14) for exchanging heat with the heat medium.

In the example of FIG. 6, the heat exchanger T10 is for the heat medium to exchange heat with the heat storage unit 3, the heat exchanger T11 is for the heat medium to exchange heat with the outside air blown by the fan 6 (a radiator), the heat exchangers T12 and T13 are for the heat medium to exchange heat with the refrigerant in the refrigerant circuit 10, and the heat exchanger T14 is provided as a cooler core in the indoor air conditioner 5 so that the heat medium can exchange heat with the indoor air.

In the heat storage management system 1 shown in FIG. 6, the heat medium circuit 2 can be switched between the heat storage mode (cold heat) shown in FIG. 6(a) and the heat storage utilization mode (cold heat) shown in FIG. 6(b) by switching the switching valve V (V10, V11) under the control of the control device shown in FIG. 2.

In the heat storage mode (cold heat), the heat medium that has become cold through the heat exchanger T13 functioning as a heat absorber in the refrigerant circuit 10 dissipates cold heat in the heat exchanger T14 of the indoor air conditioner 5, and the remaining cold heat is stored in the heat storage section 3 through the heat exchanger T10. In addition, the heat medium that has become hot through the heat exchanger T12 functioning as a radiator in the refrigerant circuit 10 dissipates warm heat to the outside air through the heat exchanger T11.

In the heat storage utilization mode (cold heat), the heat medium that has been cooled through the heat exchanger T13 releases cold heat in the heat exchanger T14 of the indoor air conditioner 5, and the cold heat stored in the heat storage unit 3 cools the refrigerant in the heat exchanger T12. At this time, the refrigerant that has exchanged heat with the heat medium in the heat exchanger T12 is cooled more than in the heat storage mode (cold heat) in which heat is released to the outside air through the heat exchanger T11, which promotes a reduction in the high pressure in the refrigerant circuit and makes it possible to reduce the power consumption of the refrigerant circuit 10 during cooling operation.

The heat storage increase mode in the heat storage management system 1 shown in FIG. 6 is executed by the control of the control device 20, and in the heat storage mode (cold heat) described above, the cold storage function is increased by increasing the rotation speed of the compressor 11 in the refrigerant circuit 10, the rotation speed of the pump P (P10, P11), and the rotation speed of the fan 6.

The transition from the heat storage mode to the heat storage increase mode (heat storage amount increase control) by the control device 20 is executed based on the algorithm shown in FIG. 7. That is, when the control device 20 detects a change in environmental conditions based on the input data (step S1), it judges whether or not the change in environmental conditions is advantageous for the heat storage of the heat storage management system 1 (step S2), and if it is not advantageous (step S2: NO), it ends the control, and if it is advantageous (step S2: YES), it executes the heat storage amount increase control (step S3).

Specific examples of control for each type of input data are explained.

First, when the input data is the outside air temperature and heat is stored using the circuit configuration of the heat storage management system 1 shown in FIG. 1, if a change in the outside air temperature is detected in step S1, step S2 checks whether any of the following conditions (conditions 1A to 1C) are met, and if the condition is met, it is determined that there is an advantage (step S2: YES).

Condition 1A: Outside temperature (current outside temperature) > set value (e.g., 15°C)
Condition 1B: Amount of rise in outside air temperature (current outside air temperature) - (past outside air temperature) > set value (e.g., +5°C)
Condition 1C: Rate of change of outdoor temperature (rate of change of outdoor temperature) = {(current outdoor temperature) - (outdoor temperature before the set time)} / set time,
(Rate of change of outside air temperature)>Set value (e.g., +5°C/min)

In this case, the heat storage amount increase control (step S3) may involve, for example, switching from the heat storage mode (warm heat) shown in FIG. 3 to the heat storage increase mode (warm heat) shown in FIG. 5, and increasing the rotation speeds of the fan 6, the compressor 11 of the refrigerant circuit 10, and the pumps P (P1, P2, P3).

In addition, if the input data is the outside air temperature and cold energy is stored using the circuit configuration of the heat storage management system 1 shown in Figure 6, when a change in the outside air temperature is detected in step S1, one of the following conditions (conditions 2A to 2C) is determined in step S2, and if the condition is satisfied, it is determined that there is an advantage (step S2: YES).

Condition 2A: Low outside air temperature (current outside air temperature) < set value (e.g., 15°C)
Condition 2B: Amount of decrease in outside air temperature (current outside air temperature) - (past outside air temperature) < set value (e.g., -5°C)
Condition 2C: Rate of change of outside air temperature (rate of change of outside air temperature) < predetermined value (for example, −5° C./min)

In this case, the heat storage amount increase control (step S3) involves switching to the heat storage mode (cold heat) in FIG. 6(a) and increasing the rotation speeds of the fan 6, the compressor 11 of the refrigerant circuit 10, and the pump P (P11, P12).

The input data in step S2 can also be the amount of heat generated by the heat generating unit 4, which increases due to operating load, etc. When the input data is the amount of heat generated, and warm heat is stored using the circuit configuration of the heat storage management system 1 shown in FIG. 1, if a change in the amount of heat generated is detected in step S1, step S2 checks whether one of the following conditions (conditions 3A to 3C) is met, and if the condition is met, it is determined that there is an advantage (step S2: YES).

Condition 3A: Level of heat generation (current heat generation) > set value Condition 3B: Amount of increase in heat generation (current heat generation) - (past heat generation) > set value Condition 3C: Rate of change in heat generation (rate of change in heat generation) = {(current heat generation) - (heat generation before the set time)}/set time,
(Rate of change in heat generation) > Set value

In this case, the heat storage amount increase control (step S3) is, for example, in the heat storage mode (warm heat) shown in FIG. 3, by increasing the rotation speed of the pump P (P1), the exhaust heat of the heat generating unit 4 is effectively recovered in the heat storage unit 3 to increase the amount of heat storage.

The input data in step S2 can also be the moving speed of the moving body (for example, vehicle speed). When the input data is the moving speed and heat is stored using the circuit configuration of the heat storage management system 1 shown in FIG. 1, if a change in the moving speed is detected in step S1, step S2 checks whether one of the following conditions (conditions 4A to 4C) is met, and if the condition is met, it is determined that there is an advantage (step S2: YES).

Condition 4A: Speed of movement (current speed of movement)>set value (e.g., 40 km/h)
Condition 4B: Amount of increase in moving speed: (Current moving speed) - (Past moving speed) > Set value Condition 4C: Rate of change in moving speed: (Rate of change in moving speed) = {(Current moving speed) - (Movement speed before the set time)} / Set time,
(rate of change in moving speed)>set value (e.g., 20 km/h/min)

In this case, the heat storage increase control (step S3) is performed, for example, by switching to the heat storage increase mode of FIG. 5 and increasing the rotation speed of the fan 6, the compressor 11 of the refrigerant circuit 10, and the pump P (P1, P2, P3) to increase the amount of heat stored in the heat storage unit 3, since the wind speed of the outside air exchanging heat with the heat exchange unit T4 (radiator) becomes relatively faster and the amount of heat absorbed by the outside air can be increased.

In addition, when the input data is the moving speed and cold energy is stored using the circuit configuration of the heat storage management system 1 shown in FIG. 6, if a change in the moving speed is detected in step S1, the above-mentioned conditions 4A to 4C are judged in step S2, and if the conditions are satisfied, it is judged that there is an advantage (step S2: YES).

In this case, the heat storage amount increase control (step S3) is, for example, to switch to the heat storage mode (cold heat) in FIG. 6(a) to increase the rotation speed of the fan 6, the compressor 11 of the refrigerant circuit 10, and the pump P (P1, P2, P3) to increase the amount of heat stored in the heat storage unit 3, since the wind speed of the outside air exchanging heat with the heat exchange unit T11 (radiator) becomes relatively faster and the amount of heat released from the outside air can be increased.

The outside air temperature, heat generation amount, movement speed, etc. used in each of the above conditions may be actual measured values, or may be values calculated from actual measured values, such as the average of the actual measured values over a specified period of time (e.g., one minute). By using the aforementioned average values in each condition, short-term changes that cannot be used for heat storage can be smoothed out, allowing for more appropriate heat storage amount increase control.

The time difference between the "present" and "past" for each of the above conditions is a time difference that allows the change in the environmental conditions to be recognized as an amount of change, and can be set to, for example, about 3 to 5 minutes.

Figure 8 shows an example of a control flow when the control device 20 controls the increase in the amount of stored heat in the heat storage management system 1 shown in Figure 1. The control device 20 executes the control flow shown below, with steps S1 to S3 described above as the basic flow.

First, as described above, a change in the surrounding environment is detected based on the input data (step S1), and when a change in the surrounding environment is detected, it is determined whether or not the detected change in the surrounding environment is advantageous for the thermal storage management system 1 based on each of the conditions described above (step S2).

If the determination in step S2 is valid (step S2: YES), in this example, a further determination is made as to whether or not there is continuity (step S03). Continuity here is determined by predicting the duration for which the advantageous situation described above will continue, and if the predicted duration exceeds a predetermined time, there is continuity (step S03: YES), and if the predicted duration does not exceed the predetermined time, there is no continuity (step S03: NO).

The continuity in step S03 can be recognized by any one of information on the travel route to the current position, information on the travel route to the destination, environmental information at the current position, environmental information to the destination, information on past travel history, information on the current position and surrounding map, or a combination of information selected from these. Note that environmental information here includes, for example, information on temperature and humidity, solar radiation, weather information (rain, sunny, snow, etc.), sunshine, shade, etc.

If it is determined in step S03 that there is no continuity (step S03: NO), short-term intensive control (step S04) is executed, and the control ends. The short-term intensive control here is a control that intensively stores heat by taking advantage of favorable conditions for a short period of time, even if the conditions favorable for heat storage do not last long, and for example, increases the rotation speed of the fan 6 to increase the amount of heat absorbed from the outside air, increases the rotation speed of the pump P to increase the flow rate of the heat medium circuit 2, and increases the rotation speed of the compressor 11 to increase the capacity of the refrigerant circuit.

If it is determined in step S03 that there is continuity (step S03: YES), for example, if the outside air temperature is not below a predetermined temperature (step S05: NO), or if the outside air temperature is below a predetermined temperature (step S05: YES), it is determined whether defrosting of the heat exchange unit T4 (radiator) is necessary (step S06: NO), and the managed temperature range of the heat storage unit 3 is expanded (step S07), and then the heat storage amount increase control described above (transition from heat storage mode to heat storage increase mode) is executed (step S3).

Then, if the outside air temperature is below a predetermined temperature (step S05: YES) and defrosting of the heat exchanger T4 is necessary (step S06: YES), a defrosting operation is performed while the vehicle is moving, taking advantage of the favorable conditions for heat storage (step S09). In this defrosting operation while the vehicle is moving, the heat storage in the heat storage unit 3 is used, and the flow path for the heat medium that has passed through the heat exchanger T2 is switched to the heat exchanger T4 (the switching valve V3 is opened in three directions in the heat storage utilization mode shown in FIG. 4).

As described above, the heat storage amount increase control in step S3 increases the amount of heat storage by appropriately combining switching of the heat medium circuit 2 (transition from heat storage mode to heat storage increase mode) and increasing the rotation speed of the fan 6, pump P, and compressor 11 as described in the short-term intensive control (step S04). Note that the flow in Figure 8 above describes an example of a control flow when performing heat storage amount increase control for hot heat, but this is not limited to this, and it is possible to similarly determine whether or not there is continuity in step S03 and use short-term intensive control and heat storage amount increase control separately for heat storage amount increase control for cold heat.

The control device 20 provided in the thermal storage management system 1 is configured as one ECU connected to various ECUs (Electronic Control Units) that control the electric vehicle (EV) via an in-vehicle network L, as shown in FIG. 9.

The CPU 201 executes various programs stored in the ROM 202 to control the control device 20. The ROM 202 is a non-volatile memory. For example, the ROM 202 stores programs executed by the CPU 201, data necessary for the CPU 201 to execute the programs, etc. The RAM 203 is a main storage device such as a dynamic random access memory (DRAM) or a static random access memory (SRAM). For example, the RAM 203 functions as a work area used when the CPU 201 executes a program. The input/output I/F 204 is connected to various sensors and monitors installed in the EV, and inputs data to the CPU 201 and outputs data processed by the CPU 201. The in-vehicle communication I/F 205 is connected to the in-vehicle network L to control data transmission and reception with other ECUs set in the EV.

The control device 20 controls the heat storage management system 1 described above by a program executed by the CPU 201 when data related to the surrounding environment or data related to the driving status of the EV is input via the input/output I/F 204 or the in-vehicle communication I/F 205.
