Abstract

A quick charging device for charging a battery includes a battery with a high power density (a high-power-density battery) and a battery with a high energy density (a high-energy-density battery).

Claims

1. A quick charging device for charging a battery comprising a battery with a high power density (a high-power-density battery) and a battery with a high energy density (a high-energy-density battery).

2. The quick charging device according to claim 1, wherein the battery is quickly charged to a selected electrical capacitance in a short time solely by the high-power-density battery.

3. The quick charging device according to claim 1, wherein, when the high-power-density battery discharges, the high-power-density battery is charged by the high-energy-density battery.

4. The quick charging device according to claim 1, wherein charging and discharging are repeated by switching between the high-power-density battery and the high-energy-density battery.

5. The quick charging device according to claim 1, further comprising a boosting converter.
