PROBLEM TO BE SOLVED: To provide a charging apparatus, compatible with commercial power and regenerative power, which can charge at an optimum voltage and an optimum current from both a commercial power supply and a regenerative current, even when the performance of a battery mounted on a vehicle is irregular, which prevents overcharging and which can prolong the life of the battery. SOLUTION: A plurality of battery rows 1 which are connected in series are connected to a regenerative motor 3 via a diode 41 . Secondary sides of a plurality of DC-DC converters 51 ...5n , in which current-limiting regulators are installed a inside are connected respectively in parallel with batteries E1 ...En which are connected in series. Then, an AC-DC converter 7, which is connected to a commercial power supply 6 is connected in parallel with the secondary of the DC-DC converters 51 ...5n . In addition, a changeover device, which changes over limit current values to be set by the current-limiting regulators at the DC-DC converters 51 ...5n by the operation of the SC-DC converter 7, is installed. In addition, a diode 43 is installed between the regenerative motor 3 and primary sides of the DC-DC converters 51 to 5n . |
