  • Charging means and apparatus for secondary battery
    Patent number: 9692244
    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.
