Abstract

PURPOSE:To prevent the early deterioration of a battery due to the temperature rise of the electrolyte of the battery by decreasing the upper limit value of a current command value as the rise of the temperature of the electrolyte when the temperature of the electrolyte is the prescribed value or higher. CONSTITUTION:A function generator 20 outputs the upper limit value 100 of a current command value which is a constant value when the temperature of the electrolyte of a battery is up to t0, decreases as the rise of the temperature of the electrolyte in a range of t0 to t1 and becomes constant higher than t1. The limiter 20 limits a current command value 102 outputted from a current command value generator 6 over the upper limit value 100 to output a current command value 104. A comparator 30 controls a current converter 2 in response to a deviation between the value 104 and a motor current 106 from a current sensor 3. As described above, the early deterioration of the battery is prevented due to the temperature rise of the electrolyte of the battery.
