Abstract

L'invention se rapporte au champ technique des terminaux mobiles. L'invention concerne un procédé et un dispositif de limitation d'un courant de charge, et un dispositif électronique. Le procédé consiste : à acquérir des informations d'état de mouvement actuel et des informations d'état d'usage actuel d'un terminal mobile (0100) ; et à réguler, en fonction des informations d'état de mouvement actuel et des informations d'état d'usage actuel, un courant de charge du terminal mobile (0102). L'invention peut réguler de manière flexible un courant de charge selon un scénario dans lequel un terminal mobile est utilisé, accroissant ainsi l'efficacité de la charge.
