Abstract

Le dispositif de commande de charge de l'invention est équipé d'une interface de communication sans fil, d'un élément de commutation et d'une partie commande. La partie commande assure une commande à partir de signaux radio émis par un dispositif de communication par l'intermédiaire d'une interface de communication sans fil, et est configurée de sorte que l'élément de commutation est mis en marche ou à l'arrêt en fonction de cette commande. En outre, la partie commande est configurée de sorte qu'un signal radio incluant un message d'accusé de réception est retourné au dispositif de communication, dans le cas où un signal radio incluant une commande est reçu, non seulement au moment où une première durée prédéfinie s'est écoulée depuis le moment où la réception dudit signal radio a eu lieu, mais aussi au moment où une seconde durée de longueur différente de la première durée s'est écoulée depuis le moment susmentionné où la réception a eu lieu.
