Cooling device of water-cooled energy storage battery and control method thereof

Abstract

The invention relates to a cooling device of a water-cooled energy storage battery cooling device. The device comprises a body (1). A main water return port (1a), a main water supply port (1b), a mainwater return valve (2) and a main water supply valve (3) are arranged on the body (1), a high-temperature water chilling unit (4) and an evaporation air cooling module (5) are arranged in the body (1), and first water return ports (4a) and second water return ports (5a) are connected with the main water return port (1a). The first water supply port (4b) and the second water supply port (5b) are respectively connected with the main water supply port (1b), and a first water return valve (7), a first water supply valve (9), a water return pump (11), a second water return valve (12) and a secondwater supply valve (14) are respectively arranged on pipelines which are connected in pairs. The device has the advantages that the natural cold source is used for cooling the water-cooled battery cooling water, so that the energy consumption of battery cooling is greatly reduced.

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.
