Abstract
(EN) The present application discloses a charging apparatus, an electronic device, a charging system and a charging method. The charging apparatus is configured to charge the electronic device, and comprises a first DC-DC charger, a second DC-DC charger, a first battery and a charging terminal. The first DC-DC charger is configured to convert a direct current delivered by an adapter to charge the first battery, and is also configured to supply power to the second DC-DC charger. An input end of the second DC-DC charger is configured to receive a direct current voltage outputted by the first DC-DC charger, an output end of the second DC-DC charger is connected to the charging terminal, and the charging terminal is configured to connect to a power receiving terminal of the electronic device. The second DC-DC charger is configured to receive charging parameters sent by the electronic device, wherein the charging parameters are obtained according to voltage information of a second battery of the electronic device; and a corresponding charging voltage and a corresponding charging current are obtained according to the charging parameters, and the charging terminal is controlled to output the charging voltage and output the charging current. The charging device can reduce the power consumption generated in the electronic device and improve the efficiency in charging the second battery.
(FR) La présente demande concerne un appareil de charge, un dispositif électronique, un système de charge et un procédé de charge. L'appareil de charge est conçu pour charger le dispositif électronique, et comprend un premier chargeur CC-CC, un second chargeur CC-CC, une première batterie et une borne de charge. Le premier chargeur CC-CC est conçu pour convertir un courant continu délivré par un adaptateur afin de charger la première batterie, et est également conçu pour apporter de l'énergie au second chargeur CC-CC. Une extrémité d'entrée du second chargeur CC-CC est conçue pour recevoir une tension continue délivrée par le premier chargeur CC-CC, une extrémité de sortie du second chargeur CC-CC est connectée à la borne de charge, et la borne de charge est conçue pour se connecter à une borne de réception d'énergie du dispositif électronique. Le second chargeur CC-CC est conçu pour recevoir des paramètres de charge envoyés par le dispositif électronique, les paramètres de charge étant obtenus en fonction d'informations de tension d'une seconde batterie du dispositif électronique ; et une tension de charge correspondante et un courant de charge correspondant sont obtenus en fonction des paramètres de charge, et la borne de charge est commandée pour délivrer la tension de charge et délivrer le courant de charge. Le dispositif de charge peut réduire la consommation d'énergie produite dans le dispositif électronique et améliorer l'efficacité de charge de la seconde batterie.
