Detailed Implementation

[0043] To make the objectives, technical solutions, and advantages of this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of this application.

[0044] As mentioned in the background section, new energy vehicles, relying on electric power, suffer from power shortages. To address this, this application provides a vehicle thermal management system and a vehicle to improve the heat utilization rate of the vehicle thermal management system, thereby increasing the vehicle's driving range and alleviating the power shortage problem.

[0045] In one embodiment, such as Figure 1 As shown, a vehicle thermal management system is provided, which includes multiple thermal management modules 10, coupling modules 20, control valve modules 30 and control modules 40.

[0046] Multiple thermal management modules 10 are used to provide heat to the vehicle. The number and type of thermal management modules 10 can be determined according to the vehicle type and application requirements, and are not limited herein. A coupling module 20 is connected to each thermal management module 10 and is used to conduct heat between the thermal management modules 10. A control valve module 30 is connected to each thermal management module 10, the coupling module 20, and the control module 40, respectively, and is used to open or close under the control of the control module 40. For example, the control valve module 30 may include a two-way valve, a three-way valve, etc., and are not limited herein.

[0047] The control module 40 is connected to the control valve module 30. The control module 40 controls the on / off state of the control valve module 30 to switch the on / off state between the coupling module 20 and each thermal management module 10. For example, when the control valve module 30 is in the on state, the coupling module 20 is also in the on state with each thermal management module 10; when the control valve 30 is in the off state, the coupling module 20 is also in the off state with each thermal management module 10. It should be noted that each thermal management module 10 is independent of each other, and the on / off state between the coupling module 10 and each thermal management module 10 is also independent of each other and does not affect each other.

[0048] The vehicle thermal management system provided in the above embodiment can conduct heat between each thermal management module 10 through the coupling module 20. Therefore, under the control of the control module 30, the control valve module 40 can switch the on / off state between the coupling module 20 and each thermal management module 10 to realize heat exchange between each thermal management module 10, make full use of the heat of each thermal management module 10, thereby improving the heat utilization rate between each thermal management module 10 and increasing the vehicle's driving range.

[0049] In one embodiment, the thermal management module 10 may include any and multiple of the following: a cab thermal management module 110, a power battery thermal management module 120, an electric drive thermal management module 130, and a fuel cell thermal management module 140. For example, Figure 2 As shown, the thermal management module 10 includes a cab thermal management module 110, a power battery thermal management module 120, an electric drive thermal management module 130, and a fuel cell thermal management module 140. Among them, the cab thermal management module 110 is used to provide heat to the vehicle's cab and belongs to the low-temperature module category.

[0050] The power battery thermal management module 120 is connected to the cab thermal management module 110 and the electric drive thermal management module 130 respectively through the coupling module 20.

The power battery thermal management module 120 is also a low temperature module.

[0051] The electric drive thermal management module 130 is connected to the cab thermal management module 110 and the power battery thermal management module 120 respectively through the coupling module 20. The electric drive thermal management module 130 is used to provide residual heat to the cab thermal management module 110 and the power battery thermal management module 120. The electric drive thermal management module 130 is a medium-temperature module.

[0052] The fuel cell thermal management module 140 is connected to the cab thermal management module 110, the electric drive thermal management module 130 and the power battery thermal management module 120 respectively through the coupling module 20. The fuel cell thermal management module 140 is used to provide residual heat to the cab thermal management module 110, the electric drive thermal management module 130 and the power battery thermal management module 120. The fuel cell thermal management module 140 is a high-temperature module.

[0053] For example, a fuel cell electric vehicle (FCEV) can simultaneously have high, medium, and low temperature modules; that is, a fuel cell vehicle includes a cab thermal management module 110, a power battery thermal management module 120, an electric drive thermal management module 130, and a fuel cell thermal management module 140. Electric vehicles (EVs) and hybrid electric vehicles (HEVs) can have medium and low temperature modules; that is, electric vehicles include a cab thermal management module 110, a power battery thermal management module 120, and an electric drive thermal management module 130. The types of thermal management modules 10 included in the vehicle thermal management system can be determined according to the vehicle type and application scenario, and are not limited here.

[0054] The vehicle thermal management system provided in the above embodiments, through modular design, designs corresponding thermal management modules according to vehicle type, making the vehicle thermal management system applicable to a wider range of application scenarios and vehicle configurations, thus improving the suitability of the vehicle thermal management system. Furthermore, the residual heat of the power battery thermal management module 120 can be used in the cab thermal management module 110 and the electric drive thermal management module 130; the residual heat of the electric drive thermal management module 130 can be used in the cab thermal management module 119 and the power battery thermal management module 120; and the residual heat of the fuel cell thermal management module 140 can be used in the cab thermal management module 110, the power battery thermal management module 120, and the electric drive thermal management module 130. This achieves the recycling of the residual heat of the power battery thermal management module 120, the electric drive thermal management module 130, and the fuel cell thermal management module 140, thereby improving the heat utilization rate of the vehicle thermal management system and contributing to increased vehicle mileage.

The fuel cell drive module 141 provides drive for the vehicle. For example, the fuel cell drive module 141 may be a fuel cell engine, a fuel cell electric motor, etc., without any limitation. The first heating circuit 142 is connected to the fuel cell drive module 141, the first coupling module 210 in the coupling module 20, and the second coupling module 220 in the coupling module 20. The fuel cell stack module 143 is connected to the first heating circuit 142. The fuel cell stack module 143 provides heat to the fuel cell drive module 141, and also provides residual heat to the electric drive thermal management module 130 through the first heating circuit 142 and the first coupling module 210, and provides residual heat to the cab thermal management module 110 through the first heating circuit 142 and the second coupling module 220. The first coupling module 210 is connected to the electric drive thermal management module 130, and the second coupling module 220 is connected to the cab thermal management module 110. This enables the reuse of residual heat from the fuel cell thermal management module 140, improving the heat utilization rate of the vehicle's thermal management system and thus helping to increase the vehicle's driving range.

The first refrigeration circuit 144 is connected to a third coupling module 230 in the coupling module 20. The fuel cell refrigeration module 145 is connected to the first refrigeration circuit 144 and is used to dissipate heat from the fuel cell thermal management module 140. The fuel cell refrigeration module 145 is also used to provide surplus energy to the power battery thermal management module 120 through the first refrigeration circuit 144 and the third coupling module 230. For example, the fuel cell refrigeration module 145 can be a condenser, evaporator, etc., without any limitation. The third coupling module 230 is connected to the power battery thermal management module 120. Based on this, the surplus heat of the fuel cell thermal management module 140 can be used in the power battery thermal management module 120, further realizing the recycling of the surplus heat of the fuel cell thermal management module 140, improving the heat utilization rate of the vehicle thermal management system, and thus increasing the vehicle's driving range.

The cab heating module 110 is also used to receive residual heat from the fuel cell stack module 143 through the first heating circuit 142, the second heating circuit 111, the third heating circuit 112, and the second coupling module 220. For example, the cab heating module 110 may be a positive temperature coefficient (PTC) vehicle heater. Therefore, by using the residual heat from the fuel cell stack module 143 in the cab heating module 110, the residual heat from the fuel cell stack module 143 is recycled, improving the heat utilization rate of the vehicle thermal management system and helping to increase the vehicle's driving range.

The cab heating module 113 is also used to provide residual heat to the coolant in the storage compartment 114 through the third heating circuit 112. Based on this, the residual heat of the cab heating module 113 can be stored in the coolant, realizing the recycling of the residual heat of the cab heating module 113, thereby improving the heat utilization rate of the vehicle thermal management system and helping to increase vehicle mileage.

Therefore, by using the power battery heating module 123 to provide heat to the fuel cell drive module 141, the heating of the fuel cell drive module 141 can be accelerated, improving the efficiency of the fuel cell drive module 141 in the vehicle thermal management system, thereby contributing to improved vehicle performance. In addition, the residual heat of the fuel cell drive module 141 is used for the power battery heating module 123, realizing the recycling of the residual heat of the fuel cell drive module 141, improving the heat utilization rate of the vehicle thermal management system, and helping to increase the vehicle's driving range.

[0066] Based on the same inventive concept described above, this application also provides a vehicle that includes the vehicle thermal management system provided in any of the above embodiments. For details, please refer to the relevant content of the above embodiments, which will not be repeated here.

[0067] To better understand, Figure 3Taking the vehicle thermal management system shown as an example, for the northern version of the fuel cell electric vehicle, after starting the vehicle, the power battery thermal management module first heats the circulating water circuit through the power battery heating module 123 (such as PTC), and then transfers the heat to the fuel cell thermal management module 140 for preheating through the third coupling module 230. At the same time, as the vehicle moves, the electric drive thermal management module synchronously transfers the generated heat energy to the fuel cell thermal management module 140 through the first coupling module 210. Meanwhile, the cab stack module 115 works to accelerate the preheating of the fuel cell drive module 141 (such as the engine). After the fuel cell engine is working normally, it synchronously transfers the heat energy to the cab thermal management module 110 through the second coupling module 220. At the same time, the power battery heating module 123 stops working, and the energy is transferred to the power battery thermal management module 120 in reverse through the third coupling module 230, so that the power battery 121 is at the optimal operating temperature, achieving optimal operation of each module. For the southern version of the fuel cell electric vehicle, due to the high ambient temperature, the power battery heating module 123 and the cab fuel cell stack module 115 are removed. All coupling modules then serve no heat transfer function, only acting as piping connections. For the all-season version, the power rating of the power battery heating module 123 and the cab fuel cell stack module 115 is reduced, while other modules remain unchanged. For the pure electric vehicle, the fuel cell thermal management module 140 is removed, while other modules remain the same.
