Charger calibrating device and calibrating method thereof

A charger calibrating device, comprising:

• a control means, arranged for controlling a charger to be calibrated to execute a first stage charging and a second stage charging to an electronic device, and then controlling the electronic device to execute a discharging process;
• an adjustment means, arranged for adding or subtracting a predetermined high level period of a switch in a charging circuit of the charger to be calibrated from a preset adjusting amplitude to generate an updated high level period and an updated adjusting amplitude if a second stage charging time is greater than or smaller than a typical charging time;
• and
• a repeated substitution means, arranged for substituting the predetermined high level period and the preset adjusting amplitude by the updated high level period and the updated adjusting amplitude respectively, and terminating calibration when the aforementioned calibrating loop is repeated for a predetermined number of times.

A charger calibrating method, comprising the steps of:

• using a control module to control a charger to be calibrated to perform a first stage charging and a second stage charging to an electronic device;
• using the control module to control the electronic device to execute a discharging process;
• if a second stage charging time is greater than or smaller than a typical charging time, using a processing module to execute an adjusting process to add or subtract a predetermined high level period of a switch in a charging circuit of the charger to be calibrated from a preset adjusting amplitude to generate an updated high level period and an updated adjusting amplitude;
• and
• using the processing module to substitute the predetermined high level period and the preset adjusting amplitude by the updated high level period and the updated adjusting amplitude respectively, and then terminating calibration when the aforementioned calibrating loop is repeated for a predetermined number of times.
