ELECTRONIC DEVICE AND METHOD OF CONTROLLING ELECTRONIC DEVICES

摘要

An electronic device, using in common portions of a charging passage to a secondary battery and a signal passage in a receiver so that the signal reception current involved in signal reception serves as a charging current to the secondary battery, bypasses the charging current involved in signal- reception even if the voltage of the secondary battery is in the vicinity of an allowable voltage, thereby controlling the voltage of the secondary battery such that it will not exceed the allowable voltage.
