ABSTRACT:
An intelligent lithium-battery-activating charging device is connectable between a charging power source and an application electrical device and contains an internal circuit that builds up a charging/discharging mode to correspond the charging power source to a lithium battery accommodated in the application electrical device. After a short time period of charging, which is short enough that the voltage detection circuit inside the application electrical device cannot properly respond, a time period of discharging follows and then discharging is stopped, so that the detection performed by the voltage detection circuit is delayed until the cycles of short time period charging and discharging are completed. If the detection shows the battery is not fully charged, then the charging operation starts again. During the charging process, ions are moved in one direction in one moment and then reversed in the next moment so that built up of deposition on electrodes can be avoided.
