Abstract

The invention relates to battery energy storage equipment and a thermal management system thereof, belonging to the technical field of battery energy storage. According to the thermal management system, all battery modules are separately provided with a liquid circulation branch, a liquid circulation pipeline is arranged in a battery pack formed by the at least two battery modules, all the liquidcirculation branches are in parallel connection with the liquid circulation pipelines of the corresponding battery packs; water pumps are respectively arranged on the liquid circulation pipelines. Theliquid circulation branches corresponding to the battery modules are controlled to be communicated with the liquid circulation pipelines according to the temperature of all the battery modules, so that a circulating system is formed; therefore, the temperature of all the battery modules can be adjusted, a battery is enabled to work in a suitable temperature range to the utmost extent, and the service life of the whole battery energy storage equipment is further prolonged.

Description

technical field [0001] The invention relates to a battery energy storage device and a thermal management system thereof, belonging to the technical field of battery energy storage. Background technique [0002] In recent years, the field of energy storage has developed rapidly, but due to the temperature characteristics of the battery, the capacity of the battery will be greatly affected under high and low temperature conditions, and even affect the service life. The stability of energy storage devices is of great significance. Because some base stations are built on mountains, winter is colder and summer is hotter. At the same time, the lithium battery energy storage device for the base station is not only placed in the open air, but also requires measures such as waterproofing. This makes it difficult for the device to dissipate heat. [0003] However, the thermal management system adopted by the current battery energy storage equipment only considers the temperature co...
