MULTI-BATTERY CHARGER AND CONTROL METHOD THEREFOR

摘要

A multiple battery charger is provided. The multiple battery charger includes an input unit configured to receive or block power from a power supply unit, an output unit including a plurality of output terminals, wherein the plurality of output terminals are commonly connected to the input unit and charge a plurality of batteries, and wherein each of the plurality of output terminals includes at least one of a plurality of second switches for a selective receipt of the power from the input unit and the plurality of output terminals are controlled in a time division multiple control manner, and a switching control unit configured to transmit a pulse width modulation signal to the input unit and the output unit so as to independently control the power applied to the plurality of batteries. Accordingly, a plurality of different kinds of batteries and the same kind of batteries in which charge states are different can be simultaneously charged.
