Abstract

The invention relates to the technical field of battery energy storage systems, in particular to a liquid-cooled battery box. The liquid-cooled battery box comprises a box body, a heat transfer sleeve and a battery, a liquid inlet for injecting cooling liquid and a liquid outlet for discharging the cooling liquid are formed in the box body, a mounting hole is formed in the top of the box body, the heat transfer sleeve is embedded in the mounting hole, and the heat transfer sleeve is in sealing fit with the mounting hole; and the heat transfer sleeve extends into the box body, is used for placing a battery and is in contact fit with the battery. The liquid-cooled battery box provided by the embodiment has the technical advantages of large heat exchange area, high heat exchange efficiency and the like.

Description

technical field [0001] The invention relates to the technical field of battery energy storage systems, in particular to a liquid-cooled battery box. Background technique [0002] At present, the mainstream cooling method of battery energy storage systems at home and abroad is air cooling, that is, air-conditioning equipment is used to cool or heat up the battery and battery box, so that the battery always works in the temperature range of 15°C-35°C. [0003] The air-cooled method based on air conditioning has defects such as uneven cooling, high energy consumption, and high failure rate. The air-cooled method is being replaced by the liquid-cooled method; however, the contact area between the battery and the cooling liquid is too small in the existing liquid-cooled battery box. resulting in low heat transfer efficiency. [0004] To sum up, how to overcome the above-mentioned defects of the existing liquid-cooled battery box is a technical problem to be solved urgently by th...
