Abstract

The invention discloses a method for automatically adapting a charger to portable equipment. When the charger is connected with the portable equipment, the equipment is charged by preset charging current nIchg=nIchgDef, and a voltage value nVchg of the charger is periodically detected. In the detection of each time, nVchg is judged whether to be greater than a preset charger voltage threshold value nVchgThre or not, and the charging current for the portable equipment is stepwise increased by nIchg=nIchg+nIchgStep or decreased by nIchg=nIchg-nIchgStep according to a judgment result to realize the automatic adaptation of the charger to the portable equipment. By the method, the charger and the portable equipment can be relatively better adapted for charging, charging time and a charging degree can be relatively better processed, and the condition of charging incompletion caused by the adaptation can be well solved; and the method is convenient to operate, safe and reliable.
