Abstract:
According to an aspect, a system includes a battery configured to be charged by a power source, a charging circuit coupled to the battery, and a battery charging manager configured to communicate with the charging circuit to control a charging of the battery by the power source. The battery charging manager obtains a charge pattern including an end charge time corresponding to a time when the battery is estimated to be disconnected from the power source. The battery charging manager controls the charging circuit to charge, over a first charging period, the battery to a temporary charge level, maintain, over a relaxation period, a battery charge level between the temporary charge level and a maintenance charge level, and charge, over a second charging period after the relaxation period, the battery to a maximum battery charge level before the end charge time.
