摘要

In the present invention, a determination unit (12) sets a first threshold (Vf1) that is compared to the measured value of charging current and a second threshold (Vf2) that is compared to the measured value of discharging current to different values. Also, the first threshold value (Vf1) with respect to charging current is set to a higher (greater) value than the second threshold value (Vf2) with respect to discharging current.
