Abstract
A power supply device includes a measurement unit that measures at least one of a voltage and a current of a lithium ion battery, a peak detection unit that detects at least one of a maximum value of the current and a minimum value of the voltage at regular time intervals using at least one of the voltage and the current measured by the measurement unit, and a determination unit that determines a failure of the lithium ion battery based on at least one of the maximum value of the current and the minimum value of the voltage detected at regular time intervals by the peak detection unit.
