Abstract
A battery charger is provided for charging the battery with the use of plural power converters, and the current balance control can be eliminated in the constant voltage charging operation. The battery charger includes the first to n-th power converters configured to convert the power supplied from the power supply and supply the converted power to the battery, and a charge controller configured to cause the power converters to perform a constant current charging operation, a constant power charging operation, and a constant voltage charging operation, to charge the battery. The charge controller causes the first to n-th power converters to operate in parallel in the constant current charging operation and the constant power charging operation, and causes one of the first to n-th power converters to solely operate in the constant voltage charging operation.
