ABSTRACT:
An invention to effect charging for a battery pack at the suitable time irrespective of the kind of an installed battery pack. A battery pack detects voltage, electric current, and temperature of an accommodated battery main body. When it is determined that charging for the battery main body is required, the battery pack outputs a charge request signal. Further, when it is determined that the battery main body has been brought into a full-charged state, the battery pack stops outputting of the charge request signal. When the charge request signal is inputted from the battery pack, the charge controller causes a direct current voltage supplied from an AC/DC adapter to be supplied for the battery pack, so as to start charging the battery main body of the battery pack. Further, when the continued inputting of the charge request signal is stopped, and the charging for the battery main body is stopped.
