ENERGY STORAGE DEVICE, PHOTOVOLTAIC ENERGY STORAGE SYSTEM, AND CHARGING NETWORK

An energy storage device includes a thermal management module, a battery module, a heat dissipation module, and a compressor that are separately integrated. The thermal management module includes a first heat exchanger, a first throttle valve, and a multi-way valve, and a housing of the thermal management module has an interface connected to another module. The multi-way valve in the thermal management module can switch on/off states of different valve ports to change a flow path of a coolant. In the energy storage device provided in this application, operation in a plurality of different modes may be implemented. During deployment, different modules may be connected to form an efficient coolant system, achieving good deployment flexibility and installation convenience. Subsequently, a module that needs to be updated or iterated may be simply replaced, achieving good convenience.
