Abstract
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.
Claims20
An energy storage and charging station, comprising:
- a heat exchange assembly,
- an energy storage system configured to store electric energy, and
- a charging system configured to charge an electric component, wherein the energy storage system is electrically connected to the charging system;
- the heat exchange assembly comprises at least two cooling medium loops, the at least two cooling medium loops comprise a first cooling medium loop and a second cooling medium loop, the first cooling medium loop is configured to exchange heat with the energy storage system, and the second cooling medium loop is configured to cool the charging system;
- the first cooling medium loop and the second cooling medium loop communicate or exchange heat, so that a cooling medium in the second cooling medium loop exchanges heat with the energy storage system, so as to transfer, to the energy storage system through the cooling medium loop, heat generated when the charging system works;
- the heat exchange assembly further comprises:
- a charger heat exchanger, and the charger heat exchanger is connected in the second cooling medium loop and is configured to exchange heat with the charging system;
- and
- at least one liquid heat exchanger, the liquid heat exchanger is configured to enable different cooling medium loops to exchange heat, the liquid heat exchanger comprises a first liquid heat exchange channel and a second liquid heat exchange channel, and a first liquid heat exchange channel and a second liquid heat exchange channel of a same liquid heat exchanger exchange heat.
