<p>PROBLEM TO BE SOLVED: To provide a charger which can charge even a power storage device in which deterioration has progressed, under appropriate conditions.SOLUTION: A charging circuit supplies a charging current to a power storage device. A voltage sensor measures voltage between terminals of the power storage device. A degree of deterioration sensor measures a physical quantity dependent on the degree of deterioration of the power storage device. A controller stops charging by controlling the charging circuit from a moment in time when the voltage between the terminals of the power storage device, measured by the voltage sensor, has reached the timer operation time to a moment in time when the timer operation time has elapsed, after start of charging. On the basis of the physical quantity measured by the degree of deterioration sensor, the controller sets at least one of the timer operation voltage and timer operation time.</p> |
