ENERGY STORAGE DEVICE AND TEMPERATURE ADJUSTMENT METHOD FOR ENERGY STORAGE DEVICE

A battery pack installed inside a cabinet is electrically connected to an energy storage interface and a charging current converter, which is electrically connected to a charging connector. A cooling system is configured to exchange heat with the charging current converter and the charging connector. A first heat dissipation apparatus is disposed in the cooling system. A temperature adjustment system is configured to exchange heat with the battery pack, and the cooling system and the temperature adjustment system are thermally separated. A second heat dissipation apparatus is disposed in the temperature adjustment system. A controller is configured to keep the cooling system off and turn on the temperature adjustment system in a first operating mode, turn on the cooling system and the temperature adjustment system in a second operating mode, and keep the cooling system off and turn on the temperature adjustment system in a dormant mode.
