This paper introduces the accumulator battery discharging current＇s Influence on the discharge system, the closed-loop control principle and its digital realization of current, voltage in the constant-current discharging system of accumulator battery. In the MATLAB/SIMULINK environment, the author carried out the closed-loop simulation experiments to the constant-current discharge system of accumulator battery. The experimental results showed that the discharging current of the accumulator battery could follow the current＇s set value well, and system＇s stability time and overshoot more both within the expected value.
