First Claim
Patent Images
1. A multi-functioned smart switching charger with time stage control, comprising:
- a charging device, connected to an AC power, for transforming alternating current from the AC power into fixed output direct current to charge one rechargeable battery;
a plurality of output units, each of the output units connecting with a power switch, for charging a rechargeable battery with the direct current from the charging device via the power switch connected to the charging device;
a switch control unit, connected with a plurality of switch control lines, each switch control line electrically connected with a power switch, for triggering the power switch to pass the direct current from the charging device to the output unit connected to the power switch, or not triggering the power switch to block the direct current from the charging device to the output unit connected to the power switch; and
a charging control unit, electrically connected with the switch control unit and each output unit via a signal connecting line, for detecting a charging characteristic of the rechargeable battery connected to each output unit, and controlling the switch control unit to change trigger status of each power switch by judging the charging characteristic;
wherein the charging device outputs the direct current only to one output unit per charging until the rechargeable battery under charging is fully charged, and the switch control unit only triggers one power switch or doesn'"'"'t trigger any power switch.

Abstract
A multi-functioned smart switching charger with time stage control is disclosed. The switching charger includes: a charging device, several output units, a switch control unit and a charging control unit. The charging device outputs direct current only to one output unit per charging until the rechargeable battery under charging is fully charged. The present invention provides a switching charger which utilizes only a charging device to charge connected rechargeable batteries sequentially. It saves material cost and space used. Meanwhile, charging time can be set up to off-peak hours. Power cost for charging can be saved.
