Dehumidification method and energy storage system

Abstract

The embodiment of the application provides a dehumidification method and an energy storage system. The method is applied to a control device of an energy storage system. The energy storage system comprises the control device, at least one battery cluster, a cluster rack, a temperature and humidity sensor corresponding to each battery cluster, an axial flow fan and a dehumidifier. The method comprises the following steps: obtaining first temperature and humidity data, second temperature and humidity data and outlet water temperature of cooling liquid; determining a dehumidification strategy for the energy storage system based on the first temperature and humidity data, the second temperature and humidity data and the outlet water temperature of the cooling liquid; and controlling operation of the axial flow fan and the dehumidifier based on the dehumidification strategy to dehumidify the energy storage system. The dehumidification method provided in the application can improve the timeliness of eliminating condensation, thereby reducing the occurrence probability of electrical short circuit, corrosion or thermal runaway caused by condensation.
