CHARGING METHOD, APPARATUS AND SYSTEM, CHARGER, AND CHARGEABLE DEVICE

摘要

A charging method, a charging apparatus, a charger, a chargeable device, and a charging system are provided. The charging method includes: acquiring a control current wave from a chargeable device, wherein the control current wave is a positive current pulse, a negative current pulse, or a current having a current value equal to a reference current value; if the control current wave is the positive current pulse, adjusting an output voltage of a charger to be greater than a present output voltage; if the control current wave is the negative current pulse, adjusting the output voltage of the charger to be less than the present output voltage; and if the control current is the current having the current value equal to the reference current value, maintaining the output voltage unchanged. Accordingly, an output capability of the charger is fully used, thus achieving fast charging.

1. A charging method, comprising:
acquiring a control current wave from a chargeable device, wherein the control current wave is a positive current pulse, a negative current pulse, or a current having a current value equal to a reference current value; if the control current wave is the positive current pulse, adjusting an output voltage of a charger to be greater than a present output voltage of the charger; if the control current wave is the negative current pulse, adjusting the output voltage of the charger to be less than the present output voltage of the charger; and if the control current is the current having the current value equal to the reference current value, maintaining the output voltage of the charger unchanged; wherein the positive current pulse refers to a pulse which has a current value greater than the reference current value and lasts at least for a first preset time length; wherein the negative current pulse refers to a pulse which has a current value less than the reference current value and lasts at least for a second preset time length; and wherein the reference current value is greater than zero.
