L'invention concerne un procédé de réglage de charge sans fil, consistant : à régler un paramètre d'un circuit de charge d'un dispositif chargé de nombreuses fois, et à acquérir l'intensité d'un signal de charge au niveau d'une position de charge courante à chaque fois après que le paramètre du circuit de charge du dispositif chargé a été réglé ; et à déterminer le paramètre du circuit de charge du dispositif chargé correspondant à la valeur maximale de l'intensité acquise de chaque signal de charge à titre de paramètre d'un circuit de charge courant du dispositif chargé. Un appareil de réglage de charge sans fil, un dispositif chargé et un support de stockage informatique sont également décrits.
