Abstract

Des modes de réalisation de la présente divulgation concernent un procédé et un appareil de détermination de protocole de charge, un dispositif électronique et un support de stockage lisible. Le procédé est appliqué à un premier dispositif. Le procédé consiste : à recevoir des informations de protocole de charge envoyées par un second dispositif, les informations de protocole de charge comprenant des identifiants d'au moins deux protocoles de charge pris en charge par le second dispositif ; à déterminer un protocole de charge cible sur la base des au moins deux protocoles de charge pris en charge par le second dispositif et un protocole de charge pris en charge par le premier dispositif ; et à envoyer un identifiant du protocole de charge cible au second dispositif. Selon le présent procédé, de multiples sélections du protocole de charge cible sont évitées, de sorte que le temps de sélection pour un premier dispositif de charge pour sélectionner un protocole de charge est raccourci, et le temps d'interaction entre le premier dispositif et le second dispositif avant la charge est réduit.
