Abstract
An energy-efficient and compact battery charger. The battery charger includes, among other things, a charging port, a power supply module, a battery charger control module or controller, a power control safety module, a battery charger switch, and an indicator. The controller, the power control safety module, and the battery charger switch work in conjunction with each other to control the operation of the battery charger. The controller is configured to execute a charging control process which detects the insertion of a battery pack into the charging port, controls the charging of the battery pack, and controls the illumination or display of the indicator. The power control safety module includes a power control safety circuit that is configured to prevent the charging current and/or the charging voltage from damaging the battery charger or battery pack during a malfunction.
