Abstract:
1. A charger structure comprising a charger device that comprises a detector device, a control circuit, a normal charge mode and a boosting charge mode, wherein the charger device has a built-in detector device, and the detector device is correspondingly connected to a battery; when the charger device is correspondingly connected to and charging the battery, then the detector device determines size of charge current and voltage; when the detector device determines that the battery is over-discharged based on the charge current and voltage having not reached set values after conducting a normal charging mode, then the control circuit sets the charger device to operate in the boosting charge mode to charge the over-discharged battery, wherein the boosting charge mode is set to be 1.2 to 2.5 times the voltage value of the normal charge mode.
