[0002] As the capacity of energy storage systems increases, the requirements for heat dissipation of battery modules are also getting higher and higher. Traditional air cooling can no longer meet the heat dissipation requirements of large-capacity, high-power energy storage systems. Therefore, liquid cooling technology, as an efficient heat dissipation method, has gradually been applied to the energy storage field. Liquid cooling technology removes the heat generated by the battery module through the circulation of liquid, effectively reducing the temperature of the battery module.
[0003] Energy storage liquid cooling technology circulates liquid (usually a special coolant) inside the energy storage device to remove the heat generated by the device and dissipate the heat into the environment through a radiator or cooling tower.
[0004] During the heat dissipation process of the energy storage liquid-cooled battery module, heat transfer mainly relies on sensible heat due to the principle of temperature difference heat exchange, which may cause a temperature difference between the upper and lower cells inside the module. Excessive temperature difference may lead to internal imbalanced charging and discharging, causing capacity deviation, and even battery failure, affecting the overall performance and life of the battery. In addition, the liquid cooling system also needs to consider problems such as leakage and corrosion of the coolant, which further increases the maintenance cost and difficulty of the system.
