ABSTRACT:
A battery device includes a battery cell constituted by a secondary cell, a case that houses the battery cell, and a battery-side positive electrode terminal and a battery-side negative electrode terminal electrically provided in the case and connected to the battery cell. The battery device further includes a temperature detecting unit that detects the temperature of the battery cell, a temperature control unit that heats and/or cools the battery cell when an electric current is supplied thereto, and a current control unit that divides, according to the temperature detected by the temperature detecting unit, an externally-supplied charging current supplied from the outside via the battery-side positive electrode terminal and the battery-side negative electrode terminal into a first current supplied to the battery cell and a second current supplied to the temperature control unit.
