What is a BESS cooling system?

Battery energy storage systems (BESS) are equipped with dedicated cooling systems. Precise theoretical calculations and professional CFD thermal simulations ensure temperature uniformity below 5℃ during operation. Based on cell temperatures, the BMS optimizes thermal control, regulating the operation of the cooling system to reduce energy consumption.

The cooling system uses liquid cooling to regulate the temperature of the battery energy storage system. Thermal performance analysis is conducted according to battery system operating conditions, evaluating the cooling and heating requirements of the system. This allows effective control of temperature and humidity for battery cells and key components, creating an optimal working environment, extending service life, and ensuring safe and reliable operation.

Intelligent control of the cooling system maintains the internal environment of the battery compartment. Different thermal management modes are activated according to operating conditions, keeping the internal temperature ≤35℃ and the average temperature difference between battery modules below 5℃.
