[0036] The embodiments of the present utility model are described in detail below. The embodiments described with reference to the accompanying drawings are exemplary. The embodiments of the present utility model are described in detail below.

[0037] Reference below Figure 1-Figure 4 A battery pack 100 according to an embodiment of the present invention is described. The battery pack 100 is applied to a vehicle.

[0038] like Figure 1-Figure 4 As shown, according to the battery pack 100 of the utility model, it includes: a battery cell 10, a control module 20 and a frame 30, the frame 30 includes: a side beam 31 and a longitudinal beam 32, in a first direction, the longitudinal beam 32 is connected between two opposite side beams 31 to separate the frame 30 into a first heat exchange space and a second heat exchange space, the battery cell 10 is arranged in the first heat exchange space, and the control module 20 is arranged in the second heat exchange space.

[0039] It can be understood that the battery cell 10, the control module 20 and the frame 30 constitute the main structure of the battery pack 100, and the battery cell 10 and the control module 20 are arranged in the frame 30, so that the frame 30 can limit the battery cell 10 and the control module 20, and can also protect the battery cell 10 and the control module 20, thereby improving the performance of the battery pack 100, and the side beams 31 are connected to form a "mouth" shaped structure, and the first direction is the front and rear direction. A longitudinal beam 32 is arranged between the side beams 31 on the front and rear sides, and the longitudinal beam 32 is vertically connected to the side beams 31 on the front and rear sides, so that the longitudinal beam 32 divides the frame 30 into a first heat exchange space and a second heat exchange space. The first heat exchange space can limit the battery cell 10, thereby facilitating the installation of the battery cell 10 in the frame 30, and the second heat exchange space can limit the control module 20, thereby facilitating the installation of the control module 20 in the frame 30, thereby improving the heat dissipation efficiency of the battery cell 10 and the control module 20. For example, the side beam 31 and the longitudinal beam 32 are welded to each other, so that the overall structural strength of the battery pack 100 can be improved, and after the battery pack 100 is installed in the vehicle, the overall structural strength of the vehicle can be improved, thereby improving the safety of the vehicle. For example, the side beam 31 adopts an extrusion molding process, which is simple to set up and has low cost, and can also improve the structural strength of the side beam 31.

[0040] Therefore, by setting the longitudinal beam 32 between the two side beams 31, a first heat exchange space and a second heat exchange space can be formed between the side beam 31 and the longitudinal beam 32. Such a setting can set the battery cell 10 in the first heat exchange space and the control module 20 in the second heat exchange space, so that the first heat exchange space and the second heat exchange space can dissipate heat for the battery cell 10 and the control module 20 respectively, thereby improving the performance of the battery pack 100, and the frame 30 structure can improve the overall structural strength of the battery pack 100, thereby extending the service life of the battery pack 100.

[0041] Among them, Figure 1 As shown, the longitudinal beam 32 includes: a first longitudinal beam and a second longitudinal beam. In the second direction, the first longitudinal beam and the second longitudinal beam are spaced apart from each other so that a first heat exchange space is formed between the first longitudinal beam and the second longitudinal beam and the side beam 31 located in the second direction respectively, and a second heat exchange space is formed between the first longitudinal beam and the second longitudinal beam. The first direction is perpendicular to the second direction.

[0042] That is, the second direction is the left-right direction, the first longitudinal beam and the second longitudinal beam are arranged at intervals from left to right, and the distance between the first longitudinal beam and the side beam 31 on the left is greater than the distance between the first longitudinal beam and the second longitudinal beam, and the distance between the second longitudinal beam and the side beam 31 on the right is greater than the distance between the first longitudinal beam and the second longitudinal beam, so that the space between the first longitudinal beam and the side beam 31 on the left, and the space between the second longitudinal beam and the side beam 31 on the right can form a first heat exchange space, and the space between the first longitudinal beam and the second longitudinal beam can form a second heat exchange space, and this arrangement can make the battery cell 10 and the control module 20 arranged at intervals, thereby ensuring the functions of the battery cell 10 and the control module 20. For example, when the battery cell 10 has thermal runaway, the control module 20 can be protected from being affected, thereby improving the performance of the battery pack 100.

[0043] In addition, if Figure 1 and Figure 2 As shown, the frame 30 also includes: a first cross beam 33 and a second cross beam 34, the first cross beam 33 is connected between the first longitudinal beam and a side beam 31 located in the second direction, and the second cross beam 34 is connected between the second longitudinal beam and another side beam 31 located in the second direction, so as to separate the two first heat exchange spaces into two battery cell placement areas 38 respectively. In the first direction, the side beams 31 are respectively provided with explosion-proof valves 35 in the four battery cell placement areas 38.

[0044] It can be understood that the first cross beam 33 and the second cross beam 34 are arranged opposite to each other on the left and right sides, the left end of the first cross beam 33 is connected to the middle position of the left side beam 31, the right end of the first cross beam 33 is connected to the middle position of the first longitudinal beam, and the first cross beam 33 is arranged in parallel with the side beams 31 on the front and rear sides, so that the first cross beam 33 can divide the first heat exchange space on the left side into two battery cell placement areas 38, the right end of the second cross beam 34 is connected to the middle position of the second longitudinal beam, the left end of the second cross beam 34 is connected to the middle position of the right longitudinal beam 32, and the second cross beam 34 is arranged in parallel with the side beams 31 on the front and rear sides, so that the second cross beam 34 can divide the first heat exchange space on the left side into two battery cell placement areas 38. The first heat exchange space on the right side is divided into two battery cell placement areas 38, so that the first heat exchange space can be divided into four battery cell placement areas 38, so that the four battery cells 10 will not affect each other, thereby improving the performance of the battery pack 100, and explosion-proof valves 35 are arranged on the side beams 31 corresponding to the four battery cell placement areas 38. When a battery cell 10 in one of the battery cell placement areas 38 has thermal runaway, the high-temperature flue gas only flows in the corresponding battery cell placement area 38, and then is discharged from the battery pack 100 through the explosion-proof valve 35, so as not to affect the safety of the battery cells 10 and other electrical components in other battery cell placement areas 38, thereby improving the safety of the battery pack 100.

[0045] In particular, if Figure 2 and Figure 3As shown, in the first direction, the second heat exchange space is located between two opposite longitudinal beams 32, that is, the second heat exchange space is arranged along the front-to-back direction, and the second heat exchange space is parallel to the side beams 31 on the left and right sides, so that it is convenient for the control module 20 to be set in the second heat exchange space, and then it is convenient for the control module 20 to control the battery pack 100, and it can also reduce the metal shell of the control module 20, thereby reducing the number of parts and reducing weight. The through arrangement of the second heat exchange space can also reduce the length of the connection between the control modules 20, thereby saving costs and ensuring the stability of the electrical connection.

[0046] In addition, if Figure 3 and Figure 4 As shown, the side beam 31 located in the first direction is provided with a first heat exchange inlet and outlet 36 and a second heat exchange inlet and outlet 37, the first heat exchange inlet and outlet 36 is connected to the first heat exchange space, and the second heat exchange inlet and outlet 37 is connected to the second heat exchange space. It can be understood that the first heat exchange inlet and outlet 36 and the second heat exchange inlet and outlet 37 are provided on the side beams 31 located on the front and rear sides, and the first heat exchange inlet and outlet 36 and the second heat exchange inlet and outlet 37 are arranged at intervals, so that the first heat exchange inlet and outlet 36 is connected to the first heat exchange space, and the second heat exchange inlet and outlet 37 is connected to the second heat exchange space, so that the cooling medium enters the first heat exchange space through the first heat exchange inlet and outlet 36, and enters the second heat exchange space through the second heat exchange inlet and outlet 37, thereby facilitating the cooling and heat dissipation of the battery cell 10 and the control module 20.

[0047] In particular, if Figure 3 As shown, there are two second heat exchange inlets and outlets 37, which are respectively arranged on two side beams 31 located in the first direction. The second heat exchange inlets and outlets 37 are suitable for connecting to the first motor cooling circuit or cooling system, and the second heat exchange inlets and outlets 37 are suitable for connecting to the second motor cooling circuit.

[0048] That is to say, the two second heat exchange inlets and outlets 37 are respectively located on the side beams 31 on the front and rear sides, so that the second heat exchange inlets and outlets 37 can be set on the front and rear sides of the second heat exchange space, and the second heat exchange inlet and outlet 37 located on the front side is connected to the first motor cooling circuit or cooling system, and the second heat exchange inlet and outlet 37 located on the rear side is connected to the second motor cooling circuit, so that the first motor cooling circuit or cooling system, the second heat exchange space and the second motor cooling circuit can form a loop. This arrangement can reduce the number of parts and save space for arranging cooling water pipes, thereby saving costs. In addition, the control module 20 does not need to design an independent cooling system. The control module 20 is cooled by the cooling system of the motor, thereby optimizing the composition of the cooling system and reducing the development configuration, thereby saving costs and reducing the difficulty of development.

[0049] In addition, if Figure 1 and Figure 3 As shown, the battery pack 100 also includes: a cold plate 40, the cold plate 40 is provided with a first cooling zone 41 and a second cooling zone 42, the first cooling zone 41 is provided corresponding to the first heat exchange space, and the second cooling zone 42 is provided corresponding to the second heat exchange space. It can be understood that the cold plate 40 is divided into a first cooling zone 41 and a second cooling zone 42, the first cooling zone 41 cools the first heat exchange space, and the second cooling zone 42 cools the second heat exchange space, and the first cooling zone 41 can adopt a direct cooling method to form a direct cooling cooling zone, and can also adopt a liquid cooling method to form a liquid cooling cooling zone. Such a setting can take into account both cooling and heating working modes. Similarly, the second cooling zone 42 can adopt a direct cooling method to form a direct cooling cooling zone, and can also adopt a liquid cooling method to form a liquid cooling cooling zone, so that the temperature of the first heat exchange space and the second heat exchange space can be made more uniform, thereby improving the heat dissipation effect of the battery pack 100.

[0050] In addition, if Figure 2 As shown, the control module 20 includes: a compressor controller 21, a front motor controller 22, a power distribution module 23, an OBC module 24 and a rear motor controller 25. The compressor controller 21, the front motor controller 22, the power distribution module 23, the OBC module 24 and the rear motor controller 25 are electrically connected, and the power distribution module 23 is electrically connected to the battery cell 10. In the first direction, the compressor controller 21, the front motor controller 22, the power distribution module 23, the OBC module 24 and the rear motor controller 25 are arranged in sequence from the front to the rear of the vehicle. In other words, the compressor controller 21, the power distribution module 23, the OBC (On Board Charger) module and the rear motor controller 25 are electrically connected in sequence in the front and rear directions using copper bars or wiring harnesses, so as to facilitate the use of the functions of the control module 20.

[0051] In particular, the power distribution module 23 is located in the middle of the control module 20, that is, in the middle of the four battery cell placement areas 37, so that a strong electrical connection can be formed between the power distribution module 23 and the battery cell 10 through the high-voltage connecting plate, and the long copper busbar of the high-voltage connection can be omitted, and the internal resistance and heat introduced by the copper busbar can be reduced, thereby saving costs and improving the performance of the battery pack 100. Moreover, the power distribution module 23 is integrated inside the battery pack 100, and the first cooling zone 41 can be effectively used to dissipate the heat of the electrical components in the power distribution module 23, thereby improving the performance of the electrical components, and the service life of the power distribution module 23 can be extended, thereby reducing the failure risk of the power distribution module 23. In addition, the power distribution module 23 is integrated inside the battery pack 100, and the structure of the side beam 31 can be simplified, thereby reducing the process difficulty of the side beam 31, thereby saving costs.

[0052] In addition, the control module 20 further includes: an insulating mounting member, on which the compressor controller 21, the front motor controller 22, the power distribution module 23, the OBC module 24 and the rear motor controller 25 are respectively arranged. It can be understood that the compressor controller 21, the front motor controller 22, the power distribution module 23, the OBC module 24 and the rear motor controller 25 are packaged by the insulating mounting member, and then fixed in the second heat exchange space by bolts, so that the number of parts can be reduced, and the difficulty of processing and manufacturing can be reduced, and the cost can be saved. Moreover, the wiring harness connecting the compressor controller 21, the front motor controller 22, the power distribution module 23, the OBC module 24 and the rear motor controller 25 becomes shorter, so as to facilitate the sequential connection between the compressor controller 21, the front motor controller 22, the power distribution module 23, the OBC module 24 and the rear motor controller 25, and thus the difficulty of arranging the control module 20 can be reduced. For example, the insulating mounting member is an insulating plastic, so as to facilitate the arrangement of the insulating mounting member and save costs.

[0053] In addition, if Figure 1 As shown, the battery pack 100 further includes: a first upper cover 50 and a first sealing member 60. The first upper cover 50 is provided on the side beam 31, and the first sealing member 60 is sealed between the first upper cover 50 and the side beam 31. In other words, the first upper cover 50 is located above the side beam 31, so that the first upper cover 50 can cover the upper surface of the battery cell 10, and the first sealing member 60 is provided between the first upper cover 50 and the side beam 31, so that the first upper cover 50 and the side beam 31 form a semi-enclosed structure, thereby ensuring the performance of the battery pack 100.

[0054] In addition, Figure 1 As shown, the battery pack 100 further includes: a second upper cover 70 and a second sealing member 80. The first upper cover 50 is provided with a maintenance port, which is arranged opposite to the control module 20. The second upper cover 70 is provided at the maintenance port, and the second sealing member 80 is sealed between the second upper cover 70 and the first upper cover 50. It can be understood that the first upper cover 50 is provided with a maintenance port, which is located above the control module 20, so that it is convenient for the staff to repair and maintain the control module 20 through the maintenance port. The second upper cover 70 is provided at the maintenance port, and the second upper cover 70 can be opened and closed relative to the maintenance port, so as to facilitate the installation of the control module 20 and the subsequent maintenance and overhaul. The second sealing member 80 is provided between the second upper cover 70 and the first upper cover 50, so that the performance of the battery pack 100 is not affected when the second upper cover 70 is opened for maintenance.

[0055] The vehicle according to the utility model includes: the battery pack 100 of the above embodiment, by arranging a longitudinal beam 32 between two side beams 31, so that a first heat exchange space and a second heat exchange space can be formed between the side beam 31 and the longitudinal beam 32. Such an arrangement allows the battery cell 10 to be arranged in the first heat exchange space and the control module 20 to be arranged in the second heat exchange space, so that the heat of the battery cell 10 and the control module 20 can be dissipated, thereby improving the performance of the battery pack 100, and the frame 30 structure can improve the overall structural strength of the battery pack 100, thereby extending the service life of the battery pack 100.

[0056] In addition, the vehicle further includes: a seat, which is slidably arranged on the longitudinal beam 32 in the first direction. It can be understood that the upper surfaces of the longitudinal beam 32 and the side beams 31 located on the left and right sides are arranged in the form of slide rails, so that the longitudinal beam 32 and the side beams 31 located on the left and right sides can act as slide rails for the front seats, so that the seats can be directly installed on the battery pack 100, so that the seat cross beam 33 and the seat slide rails and other structures can be omitted, thereby reducing the number of parts and the complexity of the structure, and also reducing the cost.

[0057] In addition, the vehicle also includes: a rocker beam, and the side beam 31 is at least constructed as a partial rocker beam, so as to increase the width of the battery pack 100, increase the power layout of the battery pack 100, and reduce the weight of the vehicle, thereby reducing costs and improving safety.
