Abstract
A charging apparatus includes a diode, a switch, a high-voltage conversion circuit, and a controller which determines whether a charge capacity of a low-voltage battery is above a threshold and outputs a signal for supplying power of a generator to the low-voltage battery when the charge capacity is equal to or below the threshold while outputs a signal for charging the high-voltage battery when the charge capacity is above the threshold value.
