Energy storage device and thermal management method thereof, energy storage module, energy storage system and charging network

Abstract

The application provides an energy storage device, an energy storage module, an energy storage system, a charging network and a heat management method thereof. The energy storage device comprises an energy storage module, a heat exchange module, a heat dissipation module and a heat exchange pipeline assembly. The energy storage module comprises a plurality of battery devices. At least part of the heat exchange module is embedded in a ground source to exchange heat with the ground source. At least part of the heat dissipation module is exposed to an atmospheric source to exchange heat with the atmospheric source. The heat exchange pipeline assembly is used to circulate a heat exchange medium. The heat exchange pipeline assembly comprises a main heat exchange pipeline, a first bypass pipeline, a second bypass pipeline and a third bypass pipeline. The heat exchange module and the heat dissipation module can exchange heat with the battery devices. The energy storage device provided by the application has low operating power consumption, thereby effectively improving the energy storage efficiency of the energy storage device.
