Description

technical field

[0001] The invention relates to the technical field of energy storage battery cooling, in particular to a cooling device for a water-cooled energy storage battery and a control method thereof. Background technique

[0002] The cooling technology of the energy storage battery is gradually converted from air cooling to water cooling, and the target value of the supply temperature of the battery cooling water is T 0 Generally between 17°C and 21°C, water cooling can better control the battery temperature, the temperature difference between the battery packs is smaller, and the battery life is longer.

[0003] At present, the measure for cooling the cooling water of the water-cooled battery is to configure a chiller and simply use mechanical refrigeration. However, this method has high energy consumption, high cost, and single method, which cannot make full use of environmental resources, resulting in waste of energy and loss of funds.
