Patent ID: 8084995

Claim:
An intelligent lithium-battery-activating charging device, comprising an enclosure containing an operation circuit, which is composed of a charging power input terminal, a controllable charging power output terminal, a charge gate control circuit, a discharge gate control circuit, a discharged electricity consuming circuit, and a control circuit, the control circuit comprising a microprocessor, the charging power input terminal being connectable to an output terminal of a charging power circuit, the controllable charging power output terminal being adapted to connect to a charging terminal of a charged device, the charge gate control circuit having an input terminal connected to the charging power input terminal to receive direct-current charging power supplied by the charging power circuit, the charge gate control circuit having an output terminal, which is split into three branches, of which a first one is connected in series through the controllable charging power output terminal to the charged device, a second one is connected to a first input terminal of the control circuit, and a third one is connected in series through the discharged electricity consuming circuit to the discharge gate control circuit for grounding, the control circuit having a first output terminal connected to a gate control terminal of the charge gate control circuit, the control circuit having a second output terminal connected to a gate control terminal of the discharge gate control circuit, the control circuit having a power input terminal connected to the charging power input terminal to receive the direct-current charging power supplied from the charging power circuit, whereby by means of the control circuit respectively issuing commands to the charge gate control circuit and the discharge gate control circuit during a charging process, the charge gate control circuit and the discharge gate control circuit are alternately and repeatedly opened and closed in a controlled manner to carry out a process of successive cycles of charging and discharging, delaying voltage detection of a charging system to allow a battery to be completely charged, and whereby during the process of charging, the charged device is subjected to repeated electro-chemical stimulation to be gradually activated in respect of power accumulation performance thereof.
