PROBLEM TO BE SOLVED: To avoid the drop of motor output when an acceleration is operated to increase speed in a controller that controls the discharging of a battery that functions as a power source of a motor-driven vehicle. SOLUTION: In a battery controller, the limit values of residual capacity and temperature are stipulated to control the charging and discharging of the battery 7. The charging and discharging are controlled by the controller 3 in such a way that the residual capacity and temperature do not exceed the limit values. Also, a pedal angle detector 2 is provided to detect the angle of an accelerator pedal 1. Based on the detected results of the amount and change speed of the angle of the accelerator pedal, the controller 3 determines whether or not acceleration is operated. When accelerated, the limit is relaxed for discharging by the residual amount and temperature. |
