[0045] Optionally, the generator thermal management interface and the drive motor thermal management interface are the same interface.
[0046] As an optional implementation, considering the similar structure of the generator thermal management component and the drive motor thermal management component, components can be shared between them, and the generator thermal management interface and the drive motor thermal management interface can be simplified into a single interface.

For example, when the thermal management controller detects that the battery temperature is overheated, it controls the battery thermal management component to cool the battery.
[0050] In this application, by setting a unified thermal management controller, the number of controllers is reduced, and the temperature of each component is coordinated, thereby reducing the overall cost of the vehicle.
[0051] Optionally, the chassis of the thermal management unit is also provided with a second interface panel, which includes a communication interface for connecting the thermal management controller to the vehicle's controller area network bus.

This communication interface connects the thermal management controller to the vehicle's controller area network (CLAN) bus, allowing the thermal management controller to acquire temperature data of the target module from the CLAN bus via the communication interface. For example, after the battery temperature sensor measures the battery temperature data, it transmits the data to the thermal management controller via the CLAN bus, enabling the battery thermal management components to cool or heat the battery.
[0053] It should be noted that, in order to avoid setting up too many panels on the chassis, the second interface panel and the first interface panel mentioned above can be the same panel.
