Abstract: A battery housing, a battery pack, and a vehicle are provided. The battery housing includes: a tray, at least one module transverse beam, and a liquid cooling plate. A first channel is formed in the tray, and an explosion-proof valve in communication with the first channel is arranged on the tray. The module transverse beam is arranged in the tray. The module transverse beam includes an accommodating portion, at least a part of a bottom of the accommodating portion is depressed downward to form a groove that can accommodate gas, and an opening is arranged at at least one end that is of the groove and that is along a length direction of the module transverse beam. The liquid cooling plate is hermetically connected to an outside of a bottom of the module transverse beam, at least one connection channel is formed between the liquid cooling plate and the module transverse beam, and the opening is in communication with the first channel through the connection channel.

Abstract: The present disclosure relates to a composite temperature control plate and a battery pack. The composite temperature control plate includes a temperature control layer and a protective layer. The temperature control layer is configured to lower or raise a temperature of the battery pack. The protective layer is laminated and fixed on the temperature control layer. The protective layer includes a heat insulating layer. The heat insulating layer is made of a heat insulating material. The protective layer includes a mounting portion extending at least to an periphery of the temperature control layer. The mounting portion is configured to connect with outside. The composite temperature control plate of the present disclosure includes the mounting portion extending at least to the periphery of the temperature control layer, and the mounting portion is used as a structure for connecting with outside, so that the problem of easy deformation at the joint is solved, thereby improving the connection reliability.
