摘要： PROBLEM TO BE SOLVED: To provide a charge/discharge controller which can suppress the degradation of a single cell caused by heat generation during use.
SOLUTION: The MPU of a charge/discharge controller calculates the calorific value of each single cell after a lapse of a predetermined time period based on the charge/discharge current flowing through a battery pack, estimates the temperature of each single cell after a lapse of a predetermined time period from the temperature (S302) of the single cell detected at a temperature detecting section based on the calorific value thus calculated and preset specific heat and weight of the single cell, and determines (S305) whether the estimated temperature exceeds a preset value or not, and furthermore suppresses (S306) a calculated allowable current (S304) if the determination is made that the set value is exceeded. Thus, a temperature rise in a single cell during use can be suppressed in advance.
