Abstract
A first calculating section () calculates an allowable output power (WoutA) of the secondary battery before a ripple temperature increase operation for increasing the temperature of a secondary battery by causing a ripple current to flow in the secondary battery is performed, the allowable output power being determined in advance based on the temperature and a state of charge (SOC) of the secondary battery. A second calculating section () calculates the allowable output power (WoutB) achieved when the ripple temperature increase operation is performed. A determining section () determines whether to perform the ripple temperature increase operation so that when the allowable output power (WoutB) is equal to or greater than the allowable output power (WoutA), the ripple temperature increase operation is performed and, when the allowable output power (WoutB) is smaller than the allowable output power (WoutA), the ripple temperature increase operation is not performed.
