[0040] As described in the background technology, in the power battery industry, new energy PHEV models usually need to install battery systems and other structures on the basis of existing fuel vehicle frames, so they need to be modified and set up on the basis of existing battery packs. However, adding these battery system parts will make the structure of the battery pack complicated; and while meeting the assembly clearance of the oil and water pipes of the whole vehicle, ensuring the ground clearance of the whole vehicle requires further compression of the height space of the battery pack, resulting in difficulty in arranging the battery cells and electrical parts inside the battery pack, insufficient space, and high production costs.

[0044] Specifically, please refer to Figure 3 , Figure 3 The schematic diagram of the structure of the battery case 100 provided in this embodiment, combined with Figure 3 The battery case 100 includes a shell 10 and a partition beam 20. The shell 10 has an installation cavity 11. The partition beam 20 is arranged on the shell 10, and the installation cavity 11 is divided into a battery installation cavity 111 for installing the battery cell 200, and an electrical installation cavity 112 for installing the electrical component 300. By setting the partition beam 20, the installation cavity 11 is divided into two chambers. The battery installation cavity 111 can accommodate the battery cell 200, and the electrical installation cavity 112 can accommodate the electrical component 300, which is convenient for assembling the battery cell 200 and the electrical component 300 of the battery pack 1100 respectively, and convenient for reasonably arranging and setting other components such as oil pipes and water pipes of the whole vehicle, making full use of air, so that the overall structure of the battery pack 1100 is simplified and the cost is reduced.

[0045] Combination Figure 2 and Figure 3 It is easy to understand that the battery cell 200 is arranged in the battery cell installation cavity 111, and the electrical component 300 is arranged in the electrical installation cavity 112. Therefore, the battery shell 100 can simplify the structure of the battery pack 1100, reduce costs, and facilitate the arrangement of the battery cell 200 and the electrical component 300.

[0046] Specifically, please combine Figure 3The shell 10 includes a bottom plate 12 and a first side beam 13, a second side beam 14, a third side beam 15 and a fourth side beam 16 which are connected end to end in sequence.

The partition beam 20 is surrounded by the second side beam 14, the third side beam 15 and the fourth side beam 16, and forms a battery cell installation cavity 111 with the bottom plate 12.

[0047] That is to say, the battery cell 200 is installed on the base plate 12 and can be fixed by one or more of the partition beam 20, the second side beam 14, the third side beam 15 and the fourth side beam 16; the electrical component 300 is also installed on the base plate 12 and can also be fixed by one or more of the first side beam 13, the second side beam 14, the partition beam 20 and the fourth side beam 16.

[0048] It should be noted that, in some embodiments, the battery cell 200 can be directly fixed by the partition beam 20, the second side beam 14, the third side beam 15 and the fourth side beam 16. Of course, the battery cell 200 can also be assembled into one or more battery modules, which are respectively connected and fixed to the partition beam 20, the second side beam 14, the third side beam 15 and the fourth side beam 16 through the fixings on the sides of the battery modules, and are installed on the bottom plate 12 together, so as to achieve stable installation of the battery cell 200 or the battery module.

[0049] To facilitate the installation and fixation of the battery cell 200, please refer to Figure 4 , Figure 4 A partial structural diagram of the battery case 100 provided in this embodiment, combined with Figure 4 A plurality of cell fixing strips 121 are provided on the bottom plate 12.

In other words, the battery cell fixing strips 121 can provide positioning tracks for the battery cells 200, facilitate the installation of the battery cells 200, and also improve the strength of the bottom plate 12.

[0050] It should be noted that, in the present embodiment, the battery cell fixing bar 121 is specifically an "X"-shaped fixing bar. Through two adjacent "X"-shaped fixing bars, the two sides of the battery cell 200 can be limited and supported, thereby further improving the installation stability of the battery cell 200. At the same time, there is a certain installation space between the two adjacent "X"-shaped fixing bars and the bottom of the battery cell 200 and the base plate 12, and structures such as a buffer pad or a liquid cooling plate can be provided to facilitate buffering or heat dissipation of the battery cell 200.
