Patent ID: 8493023

Claim:
A charge apparatus used to regulate the power outputted by a power supply to charge a battery; comprising: a voltage regulating module configured to connect the power supply to the battery, and regulating electrical energy output from the power supply to charge the battery; a protection circuit detecting a voltage of the battery and generating a triggering signal when the voltage of the battery equals a preset voltage; a timing module receiving the triggering signal to begin a timing process; and a switch control module controlling the voltage regulating module to stop charging the battery when the timing process ends; wherein the timing module includes a resistor, a capacitor and a timer, the resistor and the capacitor are series connected between the voltage regulating module and ground, the timer includes a grounding contact connected to ground, a triggering contact connected to the protection circuit, an output contact connected to the switch control module, a threshold contact and a discharging contact connected to a connection between the resistor and capacitor, and a power contact connected to the voltage regulating module.
