[0020] The following disclosure provides many different implementation methods or examples for implementing various structures of the present application. To simplify the disclosure of the present application, components and arrangements for specific examples are described below. These serve only as examples and are not intended to restrict the present application.

[0021] Heat is generated during use of the battery pack. Part of the circuit of the vehicle's thermal management system is located in the battery pack to dissipate the heat generated within it.

[0022] However, the heat exchange and the flow of the cooling medium that cools the battery pack are dependent on the control of the overall vehicle thermal management system. It is not possible to independently control the flow or heat exchange of the cooling medium within the battery pack.

[0023] To solve the aforementioned technical problem of the non-independently controllable flow and heat exchange of the cooling medium in the battery pack, the present application offers a battery pack. With reference to Fig. This battery pack comprises a housing 100, a pump 200, and a heat exchanger 300. The housing 100 has a receiving chamber 110, a first channel 120, and a second channel 130, with the first channel 120 and the second channel 130 each communicating with the receiving chamber 110. The pump 200 is located outside the receiving chamber 110 and connected to the housing 100, and the pump 200 communicates with the first channel 120. The heat exchanger 300 is located outside the receiving chamber 110 and connected to the housing 100, and the heat exchanger 300 communicates with the second channel 130. The heat exchanger 300 is connected to and communicates with the pump 200.

[0024] Specifically, a cooling medium is filled into the receiving chamber 110. The battery pack also includes a battery cell, which is arranged in the receiving chamber 110 and immersed in the cooling medium.

[0025] In some embodiments, the battery pack can directly power the pump 200.

[0026] First, in the embodiments described above, the pump 200 circulates the cooling medium within the battery pack, allowing the cooling medium to flow out of the receiving chamber 110 via the second channel 130 and into the receiving chamber 110 via the first channel 120, thus creating a circulating flow. The heat exchanger 300 extracts heat from a portion of the circulating cooling medium, allowing the high-temperature cooling medium flowing out of the receiving chamber 110 to be converted into a lower-temperature cooling medium before flowing back into the receiving chamber 110 to dissipate the heat, enabling the battery cell to operate at a relatively suitable operating temperature.

[0027] Secondly, in the embodiments described above, the pump 200 communicates with the first channel 120, the heat exchanger 300 communicates with the second channel 130, and the pump 200 communicates with the heat exchanger 300. The pump 200, the heat exchanger 300, and the housing 100 with the first channel 120 and the second channel 130 can form an independent circuit. By controlling the pump 200 and the heat exchanger 300 separately, this independent circuit can be controlled separately, thus enabling flow control and heat dissipation control for the temperature-sensitive battery pack. This reduces the possibility that temperature fluctuations of the entire vehicle will disrupt the battery pack's temperature control, allowing for more precise temperature control and enabling the battery pack to operate under more suitable temperature conditions.

[0028] Thirdly, in some embodiments, the battery pack further comprises a cover plate 190, which is connected to the housing 100 and seals the receiving space 110. In the embodiments mentioned above, the independent circuit reduces the flow path of the cooling medium used for temperature control of the battery pack, thereby decreasing flow resistance and the pressure that must be applied to the housing 100. This makes it possible to lower the requirements for the tight seal between the cover plate 190 and the housing 100, and also to reduce the pressure resistance requirements of the components in the battery pack. Furthermore, the pressure reduction can decrease the possibility of accidental opening of the rupture valve and also lower the opening pressure of the rupture valve, thus making the rupture valve more sensitive and improving the safety performance of the battery pack.

[0029] Fourthly, in the above-mentioned embodiments, the risk of leakage of the cooling medium to the outside in the independent circuit is low.

[0030] Fifth, because the independent circuit is separate from other circuits, the cooling medium in the independent circuit does not mix with the cooling medium in other circuits. It is not necessary for the cooling medium to be compatible with various operating conditions, which allows the cooling medium in the independent circuit to focus on the heat dissipation requirements of the battery pack. This improves the battery pack's safety performance and heat dissipation performance. Other circuits include low-temperature heat dissipation circuits and relevant circuits in the standstill mode of the electric drive, etc.

[0031] In some embodiments, with reference to Fig. 1 and Fig. 2. The pump 200 has a suction port 210 and a pressure port 220, which communicate with each other, with the suction port 210 communicating with the first channel 120. The heat exchanger 300 has a first inlet 310 and a first outlet 320, which communicate with each other, with the first inlet 310 communicating with the pressure port 220, and the first outlet 320 communicating with the second channel 130.

[0032] The pressure port 220 of the pump 200 communicates with the first inlet 310 of the heat exchanger 300. That is, along the flow direction of the cooling medium, the pump 200 is arranged upstream of the heat exchanger 300.

[0033] It is understood that the suction opening 210 of the pump 200 forms a relative negative pressure compared to the pressure opening 220, and the pressure opening 220 forms a relative positive pressure compared to the suction opening 210.

[0034] In the embodiments described above, the communication between the suction port 210 of the pump 200 and the first channel 120, which serves as the outlet of the housing 100, causes the housing 100 to maintain a relative negative pressure with respect to the first channel 120, similar to the suction port 210. The housing 100 is located in a low-pressure position within the independent circuit, which in turn can reduce the requirements for the tight seal between the cover plate 190 and the housing 100 and lower the pressure resistance requirements for the components in the battery pack. Furthermore, the pressure reduction can decrease the possibility of accidental opening of the rupture valve and also lower the opening pressure of the rupture valve, thus making the rupture valve more sensitive and improving the safety performance of the battery pack.

[0035] In some embodiments, with reference to Fig. 3, Fig. 4, Fig. 5, and Fig. 6. The housing 100 has a first inner surface 141, a second inner surface 151, and a bottom surface, each connected to the first inner surface 141 and the second inner surface 151, respectively. The first inner surface 141, the second inner surface 151, and the bottom surface form the receiving chamber 110. The first channel 120 has a first opening 142 on the first inner surface 141, and the second channel 130 has a second opening 152 on the second inner surface 151. The maximum distance between the first opening 142 and the bottom surface is greater than the maximum distance between the second opening 152 and the bottom surface.

[0036] With reference to Fig. 4 and Fig. 6. The maximum distance between the first opening 142 and the floor surface is a first distance h1, and the maximum distance between the second opening 152 and the floor surface is a second distance h2. h1 > h2.

[0037] If the floor surface is located below the first inner surface 141 and the second inner surface 151, a larger maximum distance between the first opening 142 and the floor surface compared to the second opening 152 means that the highest point of the first opening 142 is higher than the highest point of the second opening 152.

[0038] In some embodiments, the minimum distance between the first opening 142 and the floor surface is greater than the maximum distance between the second opening 152 and the floor surface. That is, the lowest point of the first opening 142 is higher than the highest point of the second opening 152.

[0039] It is understood that the density of gas is lower than that of the cooling medium and that gas bubbles in the cooling medium naturally rise. If the height of the first opening 142 is higher than that of the second opening 152, the gas in the cooling medium can be discharged from the receiving chamber 110 via the first opening 142.

[0040] In the above-mentioned embodiments, by limiting the maximum distance between the first opening 142 and the floor surface and the maximum distance between the second opening 152 and the floor surface, the height of the first opening 142 can be set higher than that of the second opening 152, which facilitates the venting of the system, ensures the smooth circulation of the cooling medium and the stability of the cooling effect, and improves the reliability of the independent circuit.

[0041] In some embodiments, with reference to Fig. 3 and Fig. 5. The housing 100 comprises a first wall 140 and a second wall 150. The first wall 140 has a first inner surface 141, which serves to form the receiving space 110. The first channel 120 forms a first opening 142 in the first inner surface 141. The second wall 150 has a second inner surface 151. The first wall 140 and the second wall 150 are spaced apart, and the first inner surface 141 faces the second inner surface 151. The second inner surface 151 serves to form the receiving space 110. The second channel 130 forms a second opening 152 in the second inner surface 151.

[0042] Firstly, in the embodiments described above, the arrangement of the first opening 142 and the second opening 152 on opposite inner surfaces, namely the first inner surface 141 and the second inner surface 151, ensures that the cooling medium, after entering the receiving chamber 110, must traverse the entire receiving chamber 110 in order to flow out of it. This lengthens the flow path of the cooling medium within the receiving chamber 110, allowing it to completely permeate the components within the receiving chamber 110 and consequently absorbing more heat as it flows through, thus improving the cooling effect.

[0043] Secondly, the arrangement of the first opening 142 and the second opening 152 on opposite surfaces in the embodiments described above allows the cooling medium to traverse the entire receiving space 110. This enables the cooling medium to generate a more uniform flushing force within the receiving space 110, reducing flow dead zones caused by structural obstruction and thus decreasing the possibility of gas retention due to structural blockage. This minimizes the likelihood of gas buildup and its impairment of heat transfer, ultimately improving the heat dissipation performance of the battery pack.

[0044] In some embodiments, with reference to Fig. 1, Fig. 2, Fig. 3, and Fig. 5. The housing 100 further comprises a third wall 160 and a fourth wall 170. The third wall 160 is arranged between the first wall 140 and the second wall 150 and connects the first wall 140 and the second wall 150, respectively. The third wall 160 forms the receiving space 110. The fourth wall 170 and the third wall 160 are spaced apart. The first wall 140 and the second wall 150 are each connected to the fourth wall 170 and are connected on the same side of the fourth wall 170. The fourth wall 170 forms the receiving space 110. The first wall 140 has a first end face 143 that faces away from the fourth wall 170. The first channel 120 forms a first connection 144 at the first end surface 143, and the first connection 144 communicates with the pump 200. The second wall 150 has a second end surface 153, which faces away from the fourth wall 170.The second channel 130 forms a second connection 154 on the second end surface 153, and the second connection 154 is in communication with the heat exchanger 300.

[0045] In some embodiments, the pump 200 and the heat exchanger 300 are arranged on one side of the third wall 160, which faces away from the receiving chamber 110, and are connected to the third wall 160.

[0046] In some embodiments, a portion of the first wall 140 projects beyond the side of the third wall 160 facing away from the fourth wall 170, and a portion of the second wall 150 projects beyond the side of the third wall 160 facing away from the fourth wall 170. The projecting portion of the first wall 140, the projecting portion of the second wall 150, and the third wall 160 form an installation space in which the pump 200 and the heat exchanger 300 are arranged.

[0047] In the embodiment described above, the arrangement of the first port 144 and the second port 154 on the side of the first wall 140 and the second wall 150, respectively, facing away from the fourth wall 170, allows the distance between the first port 144 and the second port 154 to be kept as small as possible when the first opening 142 and the second opening 152 are located on the opposite first inner surface 141 and second inner surface 151, respectively. This reduces the flow path length of the cooling medium in the independent circuit, which in turn reduces flow resistance. As a result, the cooling medium can flow more freely, the pump 200 can be operated at lower power, and the heat dissipation effect is improved.

[0048] In some embodiments, the height of the first port 144 is greater than the height of the second port 154, so that when the cooling medium circulates outside the receiving chamber 110, it can flow by gravity sequentially through the pump 200 and the heat exchanger 300. This allows the pump 200 to operate at a lower power consumption. Furthermore, gravity ensures that the cooling medium flows into the pump 200, so that the pump 200 remains filled with cooling medium even when stationary, which facilitates the start-up of the pump 200.

[0049] In some embodiments, with reference to Fig. 3, Fig. 4, Fig. 5, and Fig. 6. The housing 100 further comprises a bottom wall 180. The first wall 140, the second wall 150, the third wall 160, and the fourth wall 170 are each connected to the bottom wall 180 and are joined on the same side of the bottom wall 180, forming the receiving space 110. In the direction from the fourth wall 170 to the third wall 160, the dimension of the first opening 142 decreases along the first wall 140 to the bottom wall 180. In the direction from the fourth wall 170 to the third wall 160, the dimension of the second opening 152 decreases along the second wall 150 to the bottom wall 180.

[0050] Specifically, with reference to Fig. 6, the dimension of the first opening 142 along the first wall 140 to the floor wall 180 is a first dimension H1. The first dimension H1 decreases in the direction from the fourth wall 170 to the third wall 160.

[0051] In some embodiments, the first dimension H1 decreases gradually in the direction from the fourth wall 170 to the third wall 160, that is, the change of the first dimension H1 in the direction from the fourth wall 170 to the third wall 160 is continuous.

[0052] In some embodiments, with reference to Fig. 6, the first dimension H1 decreases stepwise in the direction from the fourth wall 170 to the third wall 160, that is, the change of the first dimension H1 in the direction from the fourth wall 170 to the third wall 160 is not continuous.

[0053] Specifically, with reference to Fig. 4, the dimension of the second opening 152 along the second wall 150 to the floor wall 180 is a second dimension H2. The second dimension H2 decreases in the direction from the fourth wall 170 to the third wall 160.

[0054] In some embodiments, the second dimension H2 decreases gradually in the direction from the fourth wall 170 to the third wall 160, that is, the change in the second dimension H2 in the direction from the fourth wall 170 to the third wall 160 is continuous.

[0055] In some embodiments, with reference to Fig. 6, the second dimension H2 decreases stepwise in the direction from the fourth wall 170 to the third wall 160, that is, the change of the second dimension H2 in the direction from the fourth wall 170 to the third wall 160 is not continuous.

[0056] In the embodiments described above, since the first port 144 communicates with the suction port 210 of the pump 200, the relative flow velocity in the first channel 120 is higher at points closer to the first port 144 than at points farther away. By reducing the dimensions at points with higher relative flow velocities and increasing the dimensions at points with lower relative flow velocities, the flow of the cooling medium entering the first port 142 in the direction from the third wall 160 to the fourth wall 170 can be made more uniform. Similarly, since the second port 154 communicates with the discharge port 220 of the pump 200, the relative flow velocity in the second channel 130 is higher at points closer to the second port 154.By reducing the dimensions at points of higher flow velocity and increasing them at points of lower flow velocity, the flow of the cooling medium from the first opening 142 into the receiving chamber 110 in the direction from the third wall 160 to the fourth wall 170 can be made more uniform. If the cooling medium can flow relatively uniformly from the third wall 160 to the fourth wall 170 through the first opening 142 and the second opening 152, the difference in the heat carried by the cooling medium near and further away from the third wall 160 is small. This improves the uniformity of the cooling medium's heat dissipation, increases the heat dissipation effect, and enhances the efficiency of the battery pack.

[0057] In some embodiments, with reference to Fig. 1. The battery pack further comprises a pallet 400. The pallet 400 has a receiving area 410. The housing 100, the pump 200, and the heat exchanger 300 are arranged in the receiving area 410. The housing 100 is connected to the pallet 400.

[0058] In some embodiments, the pallet 400 serves to connect to a vehicle frame in order to realize the connection of the battery pack to the vehicle frame.

[0059] Firstly, in the embodiments mentioned above, the arrangement of the pump 200 and the heat exchanger 300 in the receiving area 410 makes it possible to design the battery pack with independent circuit in a more integrated manner and to reduce the risk of leakage of the cooling medium.

[0060] Secondly, the arrangement in the receiving area 410 in the above-mentioned embodiments allows the pump 200 and heat exchanger 300 to be positioned closer to the first port 144 and second port 154, which shortens the flow path of the cooling medium, reduces flow resistance and pressure loss, and increases heat dissipation efficiency.

[0061] In some embodiments, with reference to Fig. 1. The heat exchanger 300 further comprises a second inlet 330 and a second outlet 340, which communicate with each other. The battery pack further comprises an inlet pipe 500 and an outlet pipe 600. The inlet pipe 500 is guided through the pallet 400 and connected to the heat exchanger 300 and communicates with the second inlet 330. The outlet pipe 600 is guided through the pallet 400 and connected to the heat exchanger 300 and communicates with the second outlet 340.

[0062] In some embodiments, the inlet pipe 500 and the outlet pipe 600 are each an inlet port and an outlet port, respectively, which are guided through the pallet 400 to establish a connection with external lines of the battery pack and to form a circuit that can exchange heat with the independent circuit in the heat exchanger 300.

[0063] In the embodiments mentioned above, the arrangement of the inlet pipe 500 and outlet pipe 600, which are guided through the pallet 400 and connected to the heat exchanger 300, enables the circuit, which includes the inlet pipe 500, the second inlet 330, the second outlet 340, and the outlet pipe 600, to exchange heat with the independent circuit in the heat exchanger 300 in order to remove the heat of the cooling medium in the independent circuit from the battery pack and thus achieve the cooling of the battery pack.

[0064] In some embodiments, with reference to Fig. 1. The battery pack further comprises a bracket 700. The bracket 700 is connected to the housing 100. The heat exchanger 300 is connected to the bracket 700. The heat exchanger 300 is arranged at a distance from the pallet 400.

[0065] Firstly, in the embodiments mentioned above, a support 700 is attached in the receiving area 410 to facilitate the connection of the heat exchanger 300 with the inlet pipe 500 and the outlet pipe 600, in order to change the height of the heat exchanger 300, that is, to change the distance of the heat exchanger 300 to the pallet 400 in the direction from the first wall 140 to the bottom wall 180, and thus to facilitate the connection of the heat exchanger 300 with the inlet pipe 500 and the outlet pipe 600.

[0066] Secondly, in some embodiments where the first inlet 310 is connected to the pressure port 220 by a line and the first outlet 320 is connected to the second port 154 by a line, the heat exchanger 300 can be arranged at a distance from the pallet 400 by means of the arrangement of the bracket 700, so that the lines between the heat exchanger 300 and the pallet 400 can be routed, which optimizes the space allocation, makes the interior of the battery pack more compact, reduces the external dimensions of the battery pack and facilitates the arrangement of the battery pack in the vehicle.
