DETAILED DESCRIPTION

[0047] Embodiments of the present application will be described in detail below with reference to the accompanying drawings, which are described by way of example with reference to the embodiments described below, and with reference to Figures 1-17 A thermal management system 100 of a vehicle according to a first aspect embodiment of the present application is described.

[0048] As Figures 1-3As shown, a vehicle thermal management system 100 according to a first aspect embodiment of the present invention includes: a heat exchange medium output device 10, a charging component 20, and a heat exchange flow path 30.

[0049] Specifically, the heat exchange medium output device 10 can generate heat or cool. The charging unit 20 is used to charge the vehicle's battery. The heat exchange flow path 30 is connected to the heat exchange medium output device 10 and the charging unit 20, and is used to allow the heat exchange medium in the heat exchange flow path 30 to flow through the heat exchange medium output device 10 and the charging unit 20.

[0050] For example, in Figure 1 In the example, the heat exchange path 30 is located between the heat exchange medium output device 10 and the charging component 20. The heat exchange medium can be output from the heat exchange medium output device 10, flow through the heat exchange path 30 to the charging component 20, and perform heat exchange (cooling or auxiliary heating) on ​​the charging component 20. Specifically, when the vehicle starts charging, the heat exchange medium with a higher temperature in the heat exchange medium output device 10 can flow through the heat exchange path 30 to the charging component 20 to heat the charging component 20. As the charging time increases, the temperature of the charging component 20 rises, and the heat exchange medium flowing through the charging component 20 can absorb heat and cool the charging component 20.

[0051] Therefore, by setting up a heat exchange flow path 30 to connect the heat exchange medium output device 10 and the charging component 20, the vehicle's thermal management system 100 can provide auxiliary heating or cooling to the charging component 20 when the vehicle is charging at a regular charging station. This meets the heat exchange requirements of the heat exchange medium output device 10 and the charging component 20, improving the applicability of the vehicle. Furthermore, it eliminates the need for complex medium transmission channels and heat exchange devices between the charging station and the vehicle, reducing the sealing difficulty of the charging station and the charging component 20 while improving the charging safety of the entire vehicle and reducing the structural complexity and manufacturing cost of the vehicle and the charging station.

[0052] It should be noted that the heat exchange medium output device 10 can be a component on the vehicle such as the battery pack 40, motor, electronic control system, or air conditioning unit that can provide a heat exchange medium. The charging component 20 is used to connect to a DC charging pile. The heat exchange medium can be water-glycol coolant, Ra, CO, etc., and this application does not limit it.

[0053] The heat management system 100 of the vehicle according to the utility model, through setting up heat exchange flow path 30 to make heat exchange medium output device 10 and charging part 20 communicate, make the vehicle also can through the heat management system 100 of the vehicle to charging part 20 carry out auxiliary heating or cooling when charging in ordinary charging pile, namely can realize the heat exchange demand of heat exchange medium output device 10 and charging part 20, improved the applicability of whole vehicle, and need not set up complex medium transmission channel and heat exchange device between charging pile and vehicle, reduced the sealing difficulty of charging pile and charging part 20, improved the charging safety of whole vehicle at the same time, reduced the structural complexity and manufacturing cost of whole vehicle and charging pile.

[0054] According to some embodiments of the utility model, the charging part 20 is provided with a first heat exchange channel 21, the heat exchange medium output device 10 is provided with a second heat exchange channel 11, and the first heat exchange channel 21 is communicated with the second heat exchange channel 11 through the heat exchange flow path 30.

[0055] When the heat exchange medium flows out of the heat exchange medium output device 10 from the second heat exchange channel 11, it enters the first heat exchange channel 21 in the charging part 20 through the heat exchange flow path 30, and then flows out of the charging part 20 from the first heat exchange channel 21. The heat exchange medium flowing out of the charging part 20 flows into the heat exchange flow path 30, and then enters the heat exchange medium output device 10 through the second heat exchange channel 11, thus forming a heat exchange circulation loop, realizing the cooling or heating of the heat exchange medium output device 10 and the charging part 20.

[0056] By setting the first heat exchange channel 21 and the second heat exchange channel 11, a heat exchange loop is formed between the heat exchange medium output device 10 and the charging part 20, so that the heat exchange medium can cool or assist in heating the heat exchange medium output device 10 and the charging part 20, thereby realizing efficient heat exchange between the heat exchange medium output device 10 and the charging part 20, ensuring that the temperature of each component is effectively controlled, so that the temperature of the heat exchange medium output device 10 and the charging part 20 can be maintained at the optimal working temperature during charging, thereby realizing low-cost high-power fast charging and reducing the charging time of the vehicle.

[0057] In some embodiments, the first end of the first heat exchange channel 21 is communicated with the first end of the second heat exchange channel 11 through the heat exchange flow path 30, and the second end of the first heat exchange channel 21 is communicated with the second end of the second heat exchange channel 11 through the heat exchange flow path 30.

[0058] When the heat exchange medium flows out of the heat exchange medium output device 10 from the first end of the second heat exchange channel 11 and enters the heat exchange flow path 30, it enters the charging component 20 through the first end of the first heat exchange channel 21, and then flows out of the charging component 20 from the second end of the first heat exchange channel 21. The heat exchange medium flowing out of the charging component 20 re-enters the heat exchange flow path 30, and then flows into the heat exchange medium output device 10 from the second end of the second heat exchange channel 11. In this way, a heat exchange circulation loop is formed, which realizes the cooling or heating of the heat exchange medium output device 10 and the charging component 20.

[0059] By connecting the first end of the first heat exchange channel 21 with the first end of the second heat exchange channel 11, and connecting the second end of the first heat exchange channel 21 with the second end of the second heat exchange channel 11, a heat exchange circuit is formed between the heat exchange medium output device 10 and the charging component 20. This allows the heat exchange medium to cool or heat the heat exchange medium output device 10 and the charging component 20, thereby achieving efficient heat exchange between them. This ensures that the temperature of each component is effectively controlled, and that the temperature of the heat exchange medium output device 10 and the charging component 20 is maintained at the optimal operating temperature during charging. This enables low-cost, high-power fast charging and reduces the charging time of the vehicle.

[0060] Furthermore, the second heat exchange channel 11 includes a first heat exchange sub-channel 111 and a second heat exchange sub-channel 112. The first end of the first heat exchange channel 21 is connected to the first heat exchange sub-channel 111 through the heat exchange flow path 30, and the second end of the first heat exchange channel 21 is connected to the second heat exchange sub-channel 112 through the heat exchange flow path 30.

[0061] like Figures 1-4 As shown, the first heat exchange sub-channel 111 and the second heat exchange sub-channel 112 are along the width direction of the heat exchange medium output device 10 (e.g., Figure 3 The heat exchange sub-channels 111 and 112 are spaced apart in the vertical direction of the heat exchange medium output device 10, and the first heat exchange sub-channel 111 and the second heat exchange sub-channel 112 are arranged along the length direction of the heat exchange medium output device 10 (e.g., in the vertical direction). Figure 3 The first heat exchange sub-channel 111 and the second heat exchange sub-channel 112 are arranged in parallel (extending in the left and right directions).

[0062] When the heat exchange medium flows out of the heat exchange medium output device 10 from the first heat exchange sub-channel 111, it enters the heat exchange flow path 30, passes through the first end of the first heat exchange channel 21 and enters the charging component 20, and then flows out of the charging component 20 from the second end of the first heat exchange channel 21. The heat exchange medium flowing out of the charging component 20 re-enters the heat exchange flow path 30, and then flows into the heat exchange medium output device 10 from the second heat exchange sub-channel 112, thus forming a heat exchange circulation loop to achieve cooling or heating of the heat exchange medium output device 10 and the charging component 20.

[0063] By setting the first heat exchange sub-channel 111 and the second heat exchange sub-channel 112, the liquid inlet flow path and the liquid outlet flow path of the heat exchange medium on the heat exchange medium output device 10 are reasonably distributed, and the heat exchange medium flow and other parameters in the first heat exchange sub-channel 111 and the second heat exchange sub-channel 112 can be adjusted according to different heat exchange requirements, such as in different working conditions, to achieve more flexible and accurate heat exchange control.

[0064] Specifically, the thermal management system 100 includes at least two heat exchange medium output devices 10, the first end of the first heat exchange channel 21 is connected to the second heat exchange channel 11 of one of the heat exchange medium output devices 10 through the heat exchange flow path 30, and the second end of the first heat exchange channel 21 is connected to the second heat exchange channel 11 of the other heat exchange medium output device 10 through the heat exchange flow path 30.

[0065] For example, in the example of Figure 5 The first heat exchange channel 21 can be in the shape of a U, which is not specifically limited in the present application.

[0066] By connecting the first heat exchange channel 21 to at least two heat exchange medium output devices 10, the flow path and the source range of the heat exchange medium are widened, and the components on the vehicle that can provide heat exchange medium can all participate in the heat exchange cycle, improving the applicability and versatility of the thermal management system 100. Moreover, if one of the heat exchange medium output devices 10 fails, the other heat exchange medium output devices 10 that can work normally can still continue to participate in the heat exchange cycle, enhancing the reliability of the operation of the thermal management system 100.

[0067] Further, the thermal management system 100 includes at least two heat exchange medium output devices 10, the first heat exchange channel 21 includes a third heat exchange sub-channel and a fourth heat exchange sub-channel, the first end of the third heat exchange sub-channel is connected to the first end of the second heat exchange channel 11 of one of the heat exchange medium output devices 10, the first end of the fourth heat exchange sub-channel is connected to the second end of the second heat exchange channel 11 of one of the heat exchange medium output devices 10, the second end of the third heat exchange sub-channel is connected to the first end of the second heat exchange channel 11 of the other heat exchange medium output device 10, and the second end of the fourth heat exchange sub-channel is connected to the second end of the second heat exchange channel 11 of the other heat exchange medium output device 10.

[0068] For example, the third heat exchange sub-channel and the fourth heat exchange sub-channel can be arranged in a curved shape, the first end of the fourth heat exchange sub-channel is located outside the first end of the third heat exchange sub-channel, and the second end of the fourth heat exchange sub-channel is located outside the second end of the third heat exchange sub-channel (not shown in the figure), which is not specifically limited in the present application.

[0069] When the heat exchange medium flows out from the first end of the second heat exchange channel 11 of one of the heat exchange medium output devices 10, enters the charging member 20 through the first end of the third heat exchange sub-channel, flows out of the charging member 20 from the second end of the third heat exchange sub-channel, flows into the second heat exchange channel 11 of the other heat exchange medium output device 10 from the second end of the second heat exchange channel 11 of the other heat exchange medium output device 10, and then flows into the charging member 20 again through the second end of the fourth heat exchange sub-channel, flows out of the charging member 20 through the first end of the fourth heat exchange sub-channel, and then flows into the second heat exchange channel 11 of one of the heat exchange medium output devices 10 from the second end of the second heat exchange channel 11 of one of the heat exchange medium output devices 10, a heat exchange circulation loop is formed in this way, and the cooling or heating of the heat exchange medium output device 10 and the charging member 20 is realized.

[0070] By arranging the third heat exchange sub-channel and the fourth heat exchange sub-channel, the liquid inlet flow path and the liquid outlet flow path of the heat exchange medium on the charging member 20 are reasonably distributed, and the heat exchange medium flow rate and other parameters in the third heat exchange sub-channel and the fourth heat exchange sub-channel can be adjusted according to different heat exchange requirements, such as in different working conditions, to realize more flexible and accurate heat exchange control.

[0071] Specifically, the heat exchange medium output device 10 includes a battery pack 40, the battery pack 40 is connected to the charging member 20 through a heat exchange flow path 30, and the heat exchange medium flowing out of the battery pack 40 flows to the charging member 20 through the heat exchange flow path 30 during heat exchange.

[0072] When the vehicle starts charging, the heat exchange medium with a higher temperature in the battery pack 40 can flow to the charging member 20 through the heat exchange flow path 30 to heat the charging member 20, so that the current of the charging column can quickly flow to the battery pack 40. As the charging time increases, the temperature of the charging member 20 increases, and the heat exchange medium flowing through the charging member 20 can absorb heat to cool the charging member 20 while heating the battery pack 40, so that the battery pack 40 can store electricity faster, and fast charging of the vehicle is realized.

[0073] In some optional embodiments, as shown in Figure 1 The heat exchange flow path 30 includes a first heat exchange flow path 31 and a second heat exchange flow path 32, and the heat exchange medium output device 10 further includes a power distribution box 50, the power distribution box 50 is connected to the battery pack 40 through the first heat exchange flow path 31, and the power distribution box 50 is connected to the charging member 20 through the second heat exchange flow path 32. Wherein, the heat exchange medium flowing out of the battery pack 40 flows to the power distribution box 50 through the first heat exchange flow path 31, and the heat exchange medium flowing out of the power distribution box 50 flows to the charging member 20 through the second heat exchange flow path 32.

[0074] When the heat exchange medium flows out from the battery pack 40, it flows into the distribution box 50 through the first heat exchange flow path 31, and the heat exchange medium flowing out from the distribution box 50 flows into the charging member 20 through the second heat exchange flow path 32. After the heat exchange medium heats or cools the charging member 20, it flows into the distribution box 50 through the second heat exchange flow path 32, and the heat exchange medium flowing out from the distribution box 50 flows into the battery pack 40 through the first heat exchange flow path 31. In this way, a heat exchange circulation loop is formed, and the battery pack 40, the distribution box 50, and the charging member 20 are cooled or heated.

[0075] It should be noted that the distribution box 50 can be a high-voltage distribution box 50, which is used to connect the charging member 20 and the battery pack 40 and is responsible for charging and power distribution of the high-voltage system.

[0076] According to some embodiments of the present application, as shown in Figure 6 The fourth heat exchange channel 51 and the fifth heat exchange channel 52 are formed on the distribution box 50. The first end of the fourth heat exchange channel 51 is in communication with the first heat exchange flow path 31, and the first end of the fifth heat exchange channel 52 is in communication with the second heat exchange flow path 32.

[0077] As shown in Figure 6 The fourth heat exchange channel 51 and the fifth heat exchange channel 52 are arranged in a curved shape along the width direction (for example, the left-right direction in Figure 6 The first end of the fifth heat exchange channel 52 is located outside the first end of the fourth heat exchange channel 51, and the second end of the fifth heat exchange channel 52 is located outside the second end of the fourth heat exchange channel 51.

[0078] When the heat exchange medium flows out from the first heat exchange flow path 31, it enters the distribution box 50 through the first end of the fourth heat exchange channel 51. Then it flows out from the second end of the fourth heat exchange channel 51, enters the second heat exchange flow path 32, and then enters the charging member 20 through the first heat exchange flow path 21. The heat exchange medium flowing out from the charging member 20 enters the distribution box 50 again through the second end of the fifth heat exchange channel 52 and flows out from the first end of the fifth heat exchange channel 52. Then it enters the second heat exchange flow path 32 through the first heat exchange flow path 21. In this way, a heat exchange circulation loop is formed, and the battery pack 40, the distribution box 50, and the charging member 20 are cooled or heated.

[0079] By setting up a fourth heat exchange channel 51 and a fifth heat exchange channel 52, a heat exchange circuit is formed between the battery pack 40, the power distribution box 50, and the charging component 20. This allows the heat exchange medium to cool or heat the battery pack 40, the power distribution box 50, and the charging component 20, thereby achieving efficient heat exchange between them. This ensures that the temperature of each component is effectively controlled, allowing the battery pack 40, the power distribution box 50, and the charging component 20 to maintain their optimal operating temperature during charging. This enables low-cost, high-power fast charging and reduces vehicle charging time.

[0080] In some optional embodiments, the thermal management system 100 further includes a conductive heat exchanger 60, a heat exchange medium output device 10 electrically connected to the conductive heat exchanger 60, and the conductive heat exchanger 60 having a heat exchange flow path 30.

[0081] With this configuration, the conductive heat exchanger 60 can simultaneously perform electrical connection and heat exchange functions, avoiding the need to use both electrical connectors and heat exchangers, reducing the number of related components and potential failure points, and making the structure of the thermal management system 100 more compact and simple. Furthermore, connecting the heat exchange flow path 30 of the conductive heat exchanger 60 to the corresponding heat exchange channel enables more efficient heat transfer, improving the operational reliability of the thermal management system 100.

[0082] Furthermore, the conductive heat exchanger 60 includes a conductive structure 61, which is disposed outside the heat exchange flow path 30, or the heat exchange flow path 30 is disposed outside the conductive structure 61.

[0083] Specifically, the conductive structure 61 can be located on the outside of the heat exchange flow path 30 (e.g., Figure 7 and Figure 8 As shown), of course, the heat exchange path 30 is located on the outside of the conductive structure 61 (as shown). Figure 9 and Figure 10 (As shown). In this way, the staff can select the style of the conductive heat exchanger 60 according to actual needs, so that different conductive heat exchangers 60 can meet the working requirements of the thermal management system 100.

[0084] By placing the conductive structure 61 on the outside of the heat exchange flow path 30, or placing the heat exchange flow path 30 on the outside of the conductive structure 61, the conductive structure 61 and the heat exchange medium can be in direct contact, which can realize heat exchange between the conductive structure 61 and the heat exchange medium more efficiently and improve the heat exchange efficiency of the thermal management system 100.

[0085] Furthermore, when the conductive structure 61 is located outside the heat exchange flow path 30, or when the heat exchange flow path 30 is located outside the conductive structure 61, the cross-sectional area of ​​the conductive structure 61 is larger than the cross-sectional area of ​​the heat exchange flow path 30, so as to achieve sufficient heat conduction of the heat exchange medium by the conductive structure 61.

[0086] It should be noted that the conductive structure 61 can be made of copper, aluminum or the like, but is not limited thereto.

[0087] Further, the conductive heat exchange member 60 further comprises a pipe member 62 having the heat exchange flow path 30, and the pipe member 62 is sleeved on the outer periphery of the conductive structure 61, or the conductive structure 61 is sleeved on the outer periphery of the pipe member 62.

[0088] Specifically, the pipe member 62 can be sleeved on the outer periphery of the conductive structure 61 (as shown in Figure 11 and Figure 12 ), and of course, the conductive structure 61 can also be sleeved on the outer periphery of the pipe member 62 (as shown in Figure 13 and Figure 14 ). In this way, the staff can select the style of the conductive heat exchange member 60 according to the actual needs, so that different conductive heat exchange members 60 can adapt to the working requirements of the thermal management system 100.

[0089] The arrangement of the pipe member 62 provides a flow channel for the heat exchange medium, so that the heat exchange medium can circulate and flow in the pipe. When the conductive heat exchange member 60 is working, the conductive structure 61 generates heat, and the heat exchange medium can absorb the heat from the conductive structure 61 by flowing in the heat exchange flow path 30 of the pipe member 62, and then transfer the heat to other places where heat dissipation or heat utilization is required, effectively realizing heat transfer and exchange, and ensuring that the conductive structure 61 can work stably in a suitable temperature environment.

[0090] In some optional embodiments, the conductive heat exchange member 60 further comprises at least one pipe member 62 having the heat exchange flow path 30, and the at least one pipe member 62 is arranged along the circumference of the conductive structure 61.

[0091] For example, in the example of Figure 15 , the number of pipe members 62 is 2, and the two pipe members 62 are arranged along the circumference of the conductive structure 61, which can ensure that the heat is more uniformly exchanged to the heat exchange medium in the heat exchange flow path in the circumferential direction of the conductive structure 61. In this way, the staff can select the style of the conductive heat exchange member 60 according to the actual needs, so that different conductive heat exchange members 60 can adapt to the working requirements of the thermal management system 100.

[0092] In addition, the cross-sectional shape of the conductive heat exchange member 60 can be circular (as shown in Figure 7 , Figure 9 , Figure 12 , Figure 14 and Figure 15 ), and of course, the cross-sectional shape of the conductive heat exchange member 60 can also be rectangular (as shown in Figure 8 , Figure 10 , Figure 11 and Figure 13 ).The cross-sectional shape of the electrically conductive heat exchange member 60 is not limited in the present application, and has no effect on the working principle of the thermal management system 100.

[0093] In some optional embodiments, the thermal management system 100 further comprises a connecting wire 53, the connecting wire 53 comprising a first positive connecting wire 531 and a first negative connecting wire 532, two ends of the first positive connecting wire 531 being in communication with the first end of the fifth heat exchange channel 52 and the first heat exchange flow path 31 respectively, and two ends of the first negative connecting wire 532 being in communication with the first end of the fourth heat exchange channel 51 and the first heat exchange flow path 31 respectively.

[0094] For example, in the example of FIG. Figure 2 and Figure 6 , the first positive connecting wire 531 and the first negative connecting wire 532 are arranged on the outer wall of the power distribution box 50 in the height direction (e.g., the up-down direction in FIG. Figure 2 ), and the first positive connecting wire 531 and the first negative connecting wire 532 are arranged in the width direction (e.g., the left-right direction in FIG. Figure 6 ) of the power distribution box 50.

[0095] By connecting the first end of the fifth heat exchange channel 52 and the first heat exchange flow path 31 through the first positive connecting wire 531, and connecting the fourth heat exchange channel 51 and the first heat exchange flow path 31 through the first negative connecting wire 532, the flow of the heat exchange medium between the battery pack 40 and the power distribution box 50 is smoother, further ensuring the working reliability of the thermal management system 100. Moreover, the structure of the first positive connecting wire 531 and the first negative connecting wire 532 is relatively simple, facilitating later maintenance and replacement.

[0096] Further, the connecting wire 53 further comprises a second positive connecting wire 533 and a second negative connecting wire 534, two ends of the second positive connecting wire 533 being in communication with the second end of the fifth heat exchange channel 52 and the second heat exchange flow path 32 respectively, and two ends of the second negative connecting wire 534 being in communication with the second end of the fourth heat exchange channel 51 and the second heat exchange flow path 32 respectively.

[0097] For example, in the example of FIG. Figure 2 , the second positive connecting wire 533 and the second negative connecting wire 534 are arranged on the outer wall of the power distribution box 50 in the height direction (e.g., the up-down direction in FIG. Figure 6 ), and the second positive connecting wire 533 and the second negative connecting wire 534 are arranged in the width direction (e.g., the left-right direction in FIG.

[0098] The fifth heat exchange channel 52 and the second heat exchange flow path 32 are communicated through the second positive electrode connecting line 533, and the fourth heat exchange channel 51 and the second heat exchange flow path 32 are communicated through the second negative electrode connecting line 534, so that the flow of the heat exchange medium between the charging member 20 and the power distribution box 50 is smoother, and the working reliability of the thermal management system 100 is further ensured. Moreover, the structure of the second positive electrode connecting line 533 and the second negative electrode connecting line 534 is relatively simple, facilitating later maintenance and replacement.

[0099] It should be noted that the positive and negative electrodes of the connecting line 53 can be interchanged, and the heat exchange medium flows in from the positive electrode and flows out from the negative electrode, or flows in from the negative electrode and flows out from the positive electrode, which has no effect on the working principle of the thermal management system 100.

[0100] According to some embodiments of the present application, the heat exchange medium output device 10 is provided with a third heat exchange channel 12. The thermal management system 100 further comprises a first control valve 70, which is connected with the second heat exchange channel 11 and the third heat exchange channel 12 respectively, and is used for controlling the on-off between the third heat exchange channel 12 and the second heat exchange channel 11.

[0101] As shown in Figure 4 , the third heat exchange channel 12 and the first control valve 70 are arranged on the battery pack 40, and the third heat exchange channel 12 is roughly in the shape of a comb tooth, so that the third heat exchange channel 12 can spread throughout the heat exchange plate of the battery pack 40, which helps the heat exchange medium to flow through the battery pack 40 more uniformly, so that the temperature of each part of the battery pack 40 is more uniform, and local overheating or overcooling is avoided.

[0102] The arrangement of the first control valve 70 can more accurately control the flow path of the heat exchange medium, so as to realize the high efficiency of the heat exchange of the battery pack 40. By controlling the communication between the third heat exchange channel 12 and the second heat exchange channel 11 through the first control valve 70, the distribution of the heat exchange medium between different channels can be flexibly adjusted according to actual needs, so that the temperature of the battery pack 40 and the charging member 20 can be more accurately adjusted, the heat exchange efficiency is further optimized, and energy waste is avoided.

[0103] Specifically, the first control valve 70 comprises a first valve port 71, a second valve port 72 and a third valve port 73. The first valve port 71 is in communication with the second heat exchange channel 11. The second valve port 72 is in communication with the liquid inlet end of the third heat exchange channel 12, and the third valve port 73 is in communication with the liquid outlet end of the third heat exchange channel 12. The second valve port 72 is selectively in communication with one of the first valve port 71 and the third valve port 73.

[0104] For example, in the example of Figure 4 , the first control valve 70 is arranged on the battery pack 40, and the first valve port 71, the second valve port 72 and the third valve port 73 are arranged along the width direction of the battery pack 40 (for example, Figure 4The liquid inlet passage segment 121 and the liquid outlet passage segment 122 are arranged in the width direction of the battery pack 40.

[0105] When the first control valve 70 controls the second valve port 72 to communicate with the first valve port 71, the heat exchange medium can flow from the second heat exchange channel 11 to the third heat exchange channel 12, and heat exchange can be performed on the power distribution box 50 and the charging member 20 by using the heat of the battery pack 40; when the first control valve 70 controls the second valve port 72 to communicate with the third valve port 73, the heat exchange medium circulates in the battery pack 40 to perform heat exchange on the battery pack 40. By controlling the communication of the second valve port 72 with different valve ports, multiple heat management modes can be realized to adapt the heat management system 100 to different working scenarios and requirements. Moreover, the heat exchange medium can be more effectively utilized, the heat exchange process can be optimized, and the overall efficiency of the heat management system 100 can be improved.

[0106] According to some embodiments of the present application, the third heat exchange channel 12 comprises: a liquid inlet passage segment 121, a liquid outlet passage segment 122, and a plurality of connection segments 123. In the description of the present application, the meaning of "plurality" is two or more. Specifically, the plurality of connection segments 123 are spaced apart along the flow direction of the heat exchange medium, and the two ends of each connection segment 123 are respectively communicated with the liquid inlet passage segment 121 and the liquid outlet passage segment 122. Among them, when the heat exchange medium output device 10 exchanges heat, at least one of the plurality of connection segments 123 is communicated with the liquid inlet passage segment 121 and the liquid outlet passage segment 122.

[0107] As shown in Figure 4 The liquid inlet passage segment 121 and the liquid outlet passage segment 122 extend along the length direction of the battery pack 40 (for example, the left-right direction in Figure 4 The liquid inlet passage segment 121 and the liquid outlet passage segment 122 are arranged in the width direction of the battery pack 40. The number of connection segments 123 can be three, and the three connection segments 123 are arranged in parallel along the length direction of the battery pack 40 (for example, the left-right direction in Figure 4

[0108] After the heat exchange medium flows into the liquid inlet passage segment 121, it can selectively flow through at least one of the plurality of connection segments 123 and then flow into the liquid outlet passage segment 122. Since the plurality of connection segments 123 are distributed at different positions of the battery pack 40, the temperature of different positions of the battery pack 40 can be controlled in zones, thereby ensuring uniform temperature of each part of the battery pack 40 and improving heat exchange efficiency, more effectively controlling the temperature of the battery pack 40, and improving the flexibility of the heat management system 100.

[0109] Further, the connection segment 123 is provided with a second control valve 80 at the connection with the liquid inlet passage segment 121, and / or the connection segment 123 is provided with a second control valve 80 at the connection with the liquid outlet passage segment 122.

[0110] For example, in Figure 4 ​In the example shown in FIG. 1, the second control valve 80 is arranged at the connection between the connection section 123 and the liquid inlet channel section 121, and at the connection between the connection section 123 and the liquid outlet channel section 122; or, the second control valve is arranged only at the connection between the connection section 123 and the liquid inlet channel section 121 (not shown in the figure); or, the second control valve is arranged only at the connection between the connection section 123 and the liquid outlet channel section 122 (not shown in the figure).

[0111] The second control valve 80 can be arranged at the connection between the connection section 123 and the liquid inlet channel section 121 and the liquid outlet channel section 122, so that the flow of the heat exchange medium can be controlled more accurately, and the temperature can be adjusted more accurately. The second control valve 80 can be arranged to control the connection section 123 individually, so that the temperature of different positions of the battery pack 40 can be controlled in different zones, the heat exchange efficiency is further improved, the flexibility of the thermal management system 100 is improved, the reliability of the thermal management system 100 is improved, and the maintenance and repair are facilitated when a fault occurs.

[0112] In some optional embodiments, the charging member 20 is provided with a third control valve (not shown in the figure), which is arranged on the first heat exchange channel 21 and used to control the on-off state between the first heat exchange channel 21 and the heat exchange flow path 30.

[0113] The third control valve can be used to control the on-off state between the first heat exchange channel 21 and the heat exchange flow path 30 flexibly, so that whether the heat exchange medium enters the first heat exchange channel 21 to participate in heat exchange can be determined according to the specific working state of the charging member 20, the real-time heat generation, the specific temperature demand and other factors, and more accurate temperature adjustment can be realized. In addition, when the charging member 20 is in a stage of generating small heat or does not need to exchange heat, the third control valve can be used to disconnect the first heat exchange channel 21 from the heat exchange flow path 30, so that unnecessary flow of the heat exchange medium is avoided, and the additional energy consumed by driving the flow of the heat exchange medium is reduced.

[0114] According to some embodiments of the present application, the heat exchange medium output device 10 is electrically connected to the charging member 20 through the plug-in assembly 90 (not shown in the figure), and the plug-in assembly 90 has the heat exchange flow path 30.

[0115] By arranging the plug-in assembly 90 with the heat exchange flow path 30, the heat exchange medium can flow smoothly between the heat exchange medium output device 10 and the charging member 20 when the heat exchange medium output device 10 and the charging member 20 are electrically connected through the plug-in assembly 90, heat exchange is realized, the working reliability of the thermal management system 100 is further ensured, the space on the plug-in assembly 90 is fully utilized, and the integration of the thermal management system 100 is improved. In this way, the thermal management system 100 can adapt to more installation scenes, and the applicability of the thermal management system 100 is further improved.

[0116] In addition, as shown in Figure 16 and Figure 17 The battery pack 40 and the distribution box 50 can also be electrically connected through the plug-in assembly 90, and the plug-in assembly 90 has the heat exchange flow path 30, so that the heat exchange medium flows smoothly between the battery pack 40 and the distribution box 50 in the installation scenario that the battery pack 40 and the distribution box 50 are electrically connected through the plug-in assembly 90, heat exchange is achieved, and the working reliability of the thermal management system 100 is further ensured.

[0117] In some optional embodiments, as shown in Figure 3 The thermal management system 100 further comprises a connector 13 provided on the heat exchange medium output device 10, and the connector 13 has a third heat exchange sub-flow path (not shown in the figure), and two ends of the third heat exchange sub-flow path are respectively communicated with the first heat exchange flow path 31 and the second heat exchange channel 11.

[0118] Specifically, the connector 13 is arranged between the battery pack 40 and the distribution box 50, and the first heat exchange flow path 31 and the second heat exchange channel 11 are communicated through the third heat exchange sub-flow path, so that the flow of the heat exchange medium between the battery pack 40 and the distribution box 50 is more smooth, and the working reliability of the thermal management system 100 is further ensured. Moreover, the third heat exchange sub-flow path makes full use of the space on the connector 13, and the integration of the thermal management system 100 is improved.

[0119] According to the thermal management system 100 of the utility model, the specific control method is as follows:

[0120] S1, judge the connection state of the vehicle and the charging device;

[0121] S2, after confirming that the vehicle is connected with the charging device, the heat exchange medium flows out from the heat exchange medium output device 10, and the charging part 20 is heat exchanged;

[0122] S3, judge whether the temperature of the heat exchange medium output device 10 is < T, T is the minimum temperature of the heat exchange medium output device 10 set by the thermal management system 100 when the self-heating of the heat exchange medium output device 10 is started, to determine whether the heat exchange medium output device 10 needs to be heated;

[0123] S4, if it is determined that the heat exchange medium output device 10 does not need to be heated, the first control valve 70 controls the second valve port 72 to be disconnected with the first valve port 71, so that the heat exchange medium only flows through the first heat exchange sub-channel 111 and the second heat exchange sub-channel 112 in the heat exchange medium output device 10;

[0124] S4', if it is determined that the heat exchange medium output device 10 needs to be heated, the first control valve 70 controls the second valve port 72 to be communicated with the third valve port 73, and the heat exchange medium output device 10 is heated by using other components of the thermal management system 100, such as a compressor or an air conditioning device;

[0125] Or, if it is determined that the heat exchange medium output device 10 needs to be heated, the first control valve 70 controls the second valve port 72 to communicate with the first valve port 71, and the heat generated by the conductive heat exchange element 60 is used to heat the battery pack 40 together with other components of the auxiliary thermal management system 100, such as a compressor or an air conditioning device.

[0126] S5, determine whether the heat exchange medium output device 10 temperature is greater than T, T is the highest temperature set by the battery thermal management system 100 for the heat exchange medium output device 10 to stop self-heating, and whether the heat exchange medium output device 10 needs to stop heating is confirmed;

[0127] S6, if it is determined that the heat exchange medium output device 10 needs to stop heating, the first control valve 70 controls the second valve port 72 to be disconnected from the first valve port 71, and the heat is transmitted to the vehicle end energy storage device or used for cabin heating through the first valve port 71.

[0128] In this way, the integrated cooling or heating of the heat exchange medium output device 10 and the charging element 20 can be achieved, and the auxiliary heating of the heat exchange medium output device 10 can be achieved by using the thermal management system 100 of the vehicle.
