Abstract

The present disclosure provides an energy storage system, and relates to the technical field of energy storage. The energy storage system comprises an energy storage cabinet, a refrigeration device, an air exchange device, a temperature detection device and a control device. The energy storage cabinet comprises a cabinet body and a battery cluster. The cabinet body has a mounting space, and the battery cluster is arranged in the mounting space. The refrigeration device comprises an air cooling outlet, and the air cooling outlet is communicated with the mounting space. The air exchange device comprises an air suction port, and the air suction port is communicated with the mounting space. The temperature detection device is arranged in the energy storage cabinet and is used for detecting the temperature of the battery cluster and / or the mounting space. The control device is electrically connected with the temperature detection device, the refrigeration device and the air exchange device. When the temperature detected by the temperature detection device is less than a preset temperature, the control device controls the air exchange device to cool the battery cluster. When the temperature detected by the temperature detection device is greater than the preset temperature, the control device controls the refrigeration device to cool the battery cluster or controls the refrigeration device and the air exchange device to simultaneously cool the battery cluster. The energy storage system provided by the present disclosure reduces the energy consumption of thermal management.
