<p>The present invention provides a quick charging device that can perform quick charging even with a conventional meter-rate lighting power supply or a low-voltage power-service power supply, and, if a battery to be charged (an in-vehicle, battery of an electric vehicle, for example) is empty, can repeatedly perform charging at a charging rate of 30 to 50% (up to a maximum of approximately 60%). To charge an in-vehicle battery 11 of an electric vehicle (EV) 10, the quick charging device 20 includes: a converter 21 that has a rectifying function to convert an alternating current supplied from a 100-V or 200-V AC power supply into a direct current, and a boosting function; a battery (a high-power-density battery) 22A that has a high power density and an instantaneous force; and a battery (a high-energy-density battery) 22B that has a high energy density and a large energy capacity.</p> |
