Abstract:
1. An accumulating system, comprising: an accumulator battery; a charging/discharging control portion controlling charging/discharging of said accumulator battery to fall within a control range defined by a prescribed limiting value; an abnormality detecting portion detecting an abnormality of said accumulator battery based on a voltage of said accumulator battery; and an abnormality processing portion changing said prescribed limiting value so as to narrow said control range when the abnormality of said accumulator battery is detected by said abnormality detecting portion, wherein in changing said prescribed limiting value, said abnormality processing portion determines a target value of said prescribed limiting value in accordance with a temperature of said accumulator battery and calculates an absolute value of difference between a current value of said prescribed limiting value and said target value, and when said absolute value is greater than a prescribed value limiting a change amount per one control cycle in changing said prescribed limiting value from said current value to said target value, said abnormality processing portion limits said change amount per one control cycle to said prescribed value, thereby changing said prescribed limiting value stepwise from said current value to said target value.
