Description

TECHNICAL FIELD

[0002] In the process of battery charge and discharge, the battery needs to be charged and discharged to adjust and test the battery performance, which is also called battery charge and discharge. Because of long time and large current charge and discharge, the battery is inevitably abnormal and has a safety accident, and a fire occurs due to high temperature. Most of the conventional charge and discharge equipment adopts water and gas integrated fire extinguishing.
