Abstract

La présente invention concerne un procédé et un dispositif de réglage d'un courant de charge, un terminal et un support de stockage lisible par ordinateur. En surveillant la tension du chargeur, la capacité de charge du chargeur peut être déterminée en fonction de la tension du chargeur, et la tension du chargeur est ajustée de manière adaptative par réglage de l'intensité du courant du chargeur, de manière à ajuster la capacité de charge du chargeur, ce qui permet d'améliorer la stabilité et l'efficacité de charge.
