Abstract: In accordance with an embodiment, an energy storage system includes energy storage container that a temperature control system, a battery cluster, and a controller. The controller determines a specified temperature of the temperature control system corresponding to a maximum difference between an available capacity of the battery cluster and a power consumption of the temperature control system as a target temperature. The determination of the specified temperature is based on: a correspondence between the available capacity of the battery cluster and a plurality of different specified temperatures in a specified temperature set of the temperature control system, and a correspondence between the power consumption of the temperature control system and the plurality of different specified temperatures in the specified temperature set of the temperature control system. The temperature control system is configured to adjust a temperature inside the energy storage container to the target temperature.

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.
