In some embodiments, the housing 2 is disposed offset to one side of the upper cover 102 in the length direction of the case body 1.

For example, as shown in fig. 1, where the housing 2 is provided adjacent to one end of the cockpit, the electrical component 4 mounted in the second accommodation chamber must also be provided adjacent to one end of the cockpit, the length of the electrical component 4 and the connection harness in the cockpit can be reduced, thereby contributing to cost saving.

In some embodiments, the housing 2 includes a housing body 201 and a flange 202 connected, the flange 202 being disposed around the housing body 201, the flange 202 being connected to the upper cover 102.

As shown in fig. 1 to 3, the shell body 201 and the upper cover 102 are fixed by the flange 202, and the flange 202 is arranged around the shell body 201, so that the shell body 201 is stressed uniformly, which is beneficial to improving the connection stability between the shell 2 and the upper cover 102.

Optionally, the flange 202 has a first through hole 2021, and the upper cover 102 has a connection hole corresponding to the first through hole 2021. The battery pack case 100 further includes a fastener 5, the fastener 5 having a stopper portion and a connecting portion, the connecting portion being connected to the connecting hole through the first through hole 2021, the stopper portion being stopped against the flange 202 to fix the case 2 to the upper cover 102.

For example, the number of the first through holes 2021 and the number of the connecting holes are plural and correspond to each other one by one, the fastening members 5 are screws, and the connecting holes are screw holes. The screw passes through the first through hole 2021 to be in threaded connection with the corresponding connecting hole, and the screw head of the screw is stopped on the flange 202, so that the housing 2 is fixedly mounted on the upper cover 102, and the housing 2 is convenient to mount and dismount.

Of course, in other embodiments, the flange 202 and the upper cover 102 may be connected by a snap-fit or a plug-in connection.

Optionally, the flange has a first face and a second face opposite along a height direction of the case body, the first face being disposed adjacent to the upper cover, a sealing member being provided between the first face and the upper cover to seal the second accommodation chamber.

For example, the sealing member is a sealing rubber ring, and by arranging the sealing member between the second surface of the flange 202 and the upper cover 102, external air can be prevented from entering the second accommodating cavity and then entering the first accommodating cavity 101 through the wire passing hole, which is beneficial to improving the air tightness of the battery pack 1000 and further improving the working reliability of the embodiment of the utility model.

In some embodiments, the case body 1 includes a first plate and a second plate disposed opposite to each other in the height direction thereof, and the cell module 3 has a first end face 301 and a second end face 302 opposite to each other in the height direction of the case body 1, the first end face 301 being bonded to the first plate, and/or the second end face 302 being bonded to the second plate.

The first end face 301 is bonded to the first plate body, and/or the second end face 302 is bonded to the second plate body, which is understood to mean that the first end face 301 is bonded to the first plate body and the second end face 302 is not bonded to the second plate body; or the first end face 301 is not bonded to the first plate body, and the second end face 302 is bonded to the second plate body; alternatively, the first end face 301 is bonded to the first plate body, and the second end face 302 is bonded to the second plate body.

For example, the first plate is the upper cover 102, and the second plate is the bottom plate of the tank body 1. The cell module 3 may be composed of a plurality of long cells, the terminals of which are located at one side of the battery pack 1000 in the width direction, such that the cell module 3 forms opposite first and second end faces 301 and 302 in the height direction of the battery pack 1000. The first end face 301 is bonded to the first plate body, and the second end face 302 is bonded to the second plate body, so that an assembly gap between the cell module 3 and the case body 1 can be eliminated, and the space utilization and the structural strength of the battery pack 1000 can be improved.

In some embodiments, the tank body 1 includes a cooling plate 1032, the cooling plate 1032 forming a second plate body.

For example, as shown in fig. 3, the case body 1 further includes a frame 1031 and a protection plate 1033, and the frame 1031, the cooling plate 1032 and the protection plate 1033 are sequentially arranged in the height direction of the battery pack 1000, and the cooling plate 1032 forms a second plate body, so that the case body 1 is not required to be separately adhered to the battery cell module 3, which is beneficial to reducing parts of the battery pack 1000 and facilitating assembly of the battery pack 1000.

The vehicle of the embodiment of the utility model includes the battery pack 1000 described in any of the embodiments described above.
