TRAY, TRAY ASSEMBLY, BATTERY PACK ASSEMBLY AND VEHICLE

摘要

The present invention discloses a tray, a tray assembly, a battery pack assembly and a vehicle. The tray includes: a bottom plate, where the bottom plate includes a plurality of sub-bottom plates, flow channels are provided in at least some sub-bottom plates of the plurality of sub-bottom plates, and a battery assembly is suitable for being mounted on a sub-bottom plate in which a flow channel is provided; and a frame, where the frame is disposed around the bottom plate. Based on the tray according to the present invention, a volume requirement on the cavity for holding the battery assembly may be reduced, the flow channels are arranged more concisely, and a water cooling mode and an air cooling mode may be compatible. Particularly, in the water cooling mode, even if a cooling liquid leaks, the cooling liquid may directly flow outward, the battery assembly is not short-circuited, and the battery assembly is used more safely. This may play a role of relatively well protecting the battery assembly.
