Abstract
A DC/DC converter generates a voltage required by a load. A battery supplies electric power for the load as necessary. A charging circuit charges the battery. The load, the DC/DC converter, the battery, and the charging circuit are contained in a housing. The charging circuit controls a charging current to be supplied for the battery such that a total consumed electric power (a sum of electric power consumed by the load, the DC/DC converter, and the charging circuit) dose not exceed the allowable dissipation of the housing.
