ABSTRACT:
Whether electronic equipment is being used or a secondary battery is being charged is detected by measuring the electric current supplied from an electric power source to the electronic equipment. The voltage level supplied to the electronic equipment is switched corresponding to the detected result. Accordingly, the secondary battery can be charged reliably and efficiently at a higher voltage level than that used by the electronic equipment and the heat generated within the electronic equipment can be reduced. Therefore, the apparatus can be made compact and the cost thereof can be reduced. Further, the constructional parts to which the voltage from the electric power source is supplied can be operated by desirable operational characteristics.
