CHARGING MEANS AND APPARATUS FOR SECONDARY BATTERY
First Claim
1. A charging apparatus for a secondary battery, comprising:
- a plurality of power supply battery packs, each of which having at least a secondary battery and being defined a charging and a discharging sequence, each of the plurality of power supply battery packs discharging in rotation to supply power to the secondary battery;
a plurality of charge-discharge circuits, each of which being corresponding to one of the plurality of power supply battery packs, each of the plurality of charge-discharge circuits charging a corresponding power supply battery pack by an external power supply, and each of the plurality of charge-discharge circuits controlling the corresponding power supply battery pack to discharge; and
a microcontroller electrically connected to each charge-discharge circuit to control charging and discharging of each power supply battery pack corresponding to each charge-discharge circuit,wherein the microcontroller sequentially selects one of the power supply battery packs to discharge and be recharged after the discharging;
when a last power supply battery unit is recharged after discharging, the power supply battery pack which discharges firstly has been fully recharged to wait for discharging.

Abstract
A charging means and apparatus which can quickly charge the secondary battery, the apparatus includes a plurality of power supply battery packs, each power supply battery pack corresponds to a charge-discharge circuit, and a microcontroller. The microcontroller sequentially and rotationally selects one of the pluralities of power supply battery packs to charge the secondary battery, and the plurality of power supply battery packs will be recharged after the discharging. After the discharging of the last one of the plurality of power supply battery packs is completed, the power supply battery pack which discharges firstly has done the recharging process and ready to discharge a again, and thus making sure at least one power supply battery pack is in fully charged condition, which is ready to discharge anytime.
