摘要： Embodiments of this application provide an energy storage and charging station. Heat of an energy storage system and heat of a charging system are managed in a centralized manner, so that the energy storage system and the charging system can exchange heat by using a heat exchange assembly. A cooling medium in a cooling medium loop separately flows through the charging system and the energy storage system, and the charging system and the energy storage system each exchange heat with the cooling medium loop. Heat generated when the charging system works is transferred, through the cooling medium loop, to the energy storage system for use, to reduce energy consumption required to heat the energy storage system to maintain a temperature, and improve energy use efficiency.
