The research on charging control technology of storage battery in emergency power supply for mine blower

摘要

Coal mine ventilator is an important part of the mine work. It can provide a good environment to ensure the miners' personnel body health and life safety. Emergency Power Supply system also says EPS; it is a standby power when the mine ventilator has no power. It uses battery pack as energy storage equipment. Therefore, in order to ensure the battery pack has a good charging state, it is very important to develop a big power and high voltage battery pack and improve the charging and discharging control mode and the charging and discharging parameters. This paper studies the battery charging control system and shows the charging working principle of the EPS battery pack, so it puts forward a new type of storage battery charging control technology.
