Abstract: A battery apparatus includes a protection housing, at least one battery module, at least one first exhaust assembly, at least one second exhaust assembly, and a control unit. Two types of exhaust assemblies are disposed on the protection housing in the battery apparatus. One type of exhaust assembly is controlled to inject gas, and the other type of exhaust assembly is controlled to exhaust gas, so that an air flow is formed in two regions. The high-temperature and high-pressure gas exhausted by the battery module inside the protection housing is taken to an exterior of the protection housing by the battery apparatus, and heat inside the protection housing is taken away by the battery apparatus.
