Abstract:
A charger that charges a battery unit including a secondary battery, includes a receiving unit, a detection unit, a determination unit, and a control unit. The receiving unit receives, from the battery unit, battery state information indicating a state of the battery unit, if the secondary battery is being charged. The detection unit detects charge state information indicating the state of the battery unit, if the secondary battery is being charged. The determination unit determines, using the battery state information and the charge state information, whether the battery unit is in a normal state. The control unit controls charging of the secondary battery in the battery unit depending on whether the battery unit is in the normal state.
