Abstract
A multi-battery charging circuit is described and it includes an electric power detecting unit for detecting remaining amount of electric power of each battery; a charging deciding unit provided with a first amount of electric power threshold and for comparing the remaining amount detected with the first threshold; and a charging unit for charging a plurality of batteries with a first strategy in a first time period, and with a second strategy in a second time period when the remaining amount of electric power of one or more of the batteries is equal to a second amount of electric power threshold, and with a third strategy in a third time period when the remaining amount is equal to a third amount of electric power threshold.
