Abstract

Un système de charge est divulgué, comprenant une borne de charge (100), un dispositif intégré (200) et un serveur (300). Un dispositif de lecture/d'écriture (201) est intégré dans le dispositif intégré, et le dispositif intégré est configuré pour être utilisé dans une automobile. Lorsque l'automobile doit être chargée, un utilisateur conduit l'automobile jusqu'à la borne de charge, et place une carte électronique à proximité du dispositif intégré pour balayer la carte ; le dispositif intégré lit des informations de carte électronique, et envoie les informations de carte électronique à la borne de charge ; la borne de charge envoie les informations de carte électronique au serveur ; le serveur génère un signal de commande selon les informations de carte électronique, et envoie le signal de commande à la borne de charge ; la borne de charge peut fonctionner selon une instruction du signal de commande, de façon à fournir un service de charge pour l'automobile. Dans le procédé, l'utilisateur peut balayer la carte dans l'automobile ; le balayage de carte dans un véhicule est plus pratique, et le risque de perte peut être réduit.
