The inventors have noticed that with the continuous expansion of the application fields of traction batteries, market demands for the traction batteries are also expanding. During the development of vehicles, arrangement of batteries is a difficult point. Due to the numerous components in conventional vehicles, there is no space for battery mounting without significantly modifying the vehicle body. After further research, it is found that the battery is typically placed in the front compartment or trunk in conventional vehicles and is mounted on the longitudinal beam or spare tire pool of the vehicle through the bracket, resulting in weak modal characteristics for cantilever beam of the bracket and easy noise generation. In addition, the battery and a plurality of electronic modules of the power supply device are usually arranged separately, which occupies much space, such as the electric drive or thermal management space in the front compartment, thus reducing space utilization.

In view of this, the application provides a technical solution. In this technical solution, a housing is configured to be mounted on a vehicle body, and the housing includes a housing body, a first mounting part, and a second mounting part, where the housing body has an accommodating cavity; the first mounting part is provided on the housing body and is configured to fix the battery in the accommodating cavity; and the second mounting part is provided on the housing body and is configured to fix the plurality of electronic modules in the accommodating cavity. In the foregoing solution, the battery and the plurality of electronic modules can be fixed in the accommodating cavity of the housing through the first mounting part and the second mounting part of the housing respectively, then the housing is fixed in the vehicle, and the battery and the plurality of electronic modules are mounted as a whole in the vehicle body of the vehicle. This can improve the space utilization of the vehicle, enhance the modal characteristics of the battery, and reduce vehicle noise.
