Implementation of Intelligent Charger Used for Coal Mine Vehicle Batteries

A kind of fast charging craft of lead acid batteries was introduces,pulse charging with variable current and a new switching mode charger based on DSP technology used for coal mine vehicle batteries.The principle of the main converter of the charger was analysed and the system structure and control method were presented.The experimental results show that pulse charging with variable current can effectively remove the polarization of the battery under high current charging mode,speed up the charging process and increase the charging efficiency with small amount of resolved gas and low temperature rise.
