Abstract
(EN)
A method and device for controlling a wireless charging device, and a wireless charging device. The method comprises: receiving a power adjustment value sent by a terminal; and adjusting, according to the power adjustment value, at least one of an output voltage and an output frequency of a wireless AC power signal, so as to adjust an output power of the wireless AC power signal. The method and device for controlling a wireless charging device and the wireless charging device can ensure wireless charging efficiency for a terminal while meeting a change in power requirements for the battery load of the terminal, and can prevent the terminal from being overheated during a high-power charging process. The invention has a wide application range.
(FR)
L’invention concerne un procédé et un dispositif destinés à commander un dispositif chargeur sans fil, et un dispositif chargeur sans fil. Le procédé consiste : à recevoir une valeur de réglage de puissance envoyée par un terminal ; et à régler, en fonction de la valeur de réglage de puissance, au moins une valeur parmi une tension de sortie et une fréquence de sortie d’un signal de puissance en CA sans fil, afin de régler une puissance de sortie du signal de puissance en CA sans fil. Le procédé et le dispositif destinés à commander un dispositif chargeur sans fil et le dispositif chargeur sans fil peuvent assurer l’efficacité de charge sans fil pour un terminal tout en satisfaisant à des exigences de changement de puissance pour la charge de batterie du terminal, et peut empêcher que le terminal soit surchauffé durant un processus de charge à haute puissance. L’invention a une plage d’application étendue.
(ZH)
一种无线充电装置的控制方法、装置以及无线充电装置,该方法包括:接收终端发送的功率调整值;根据功率调整值对无线交流功率信号的输出电压和输出频率中的至少一项进行调整,以调整无线交流功率信号的输出功率。上述无线充电装置的控制方法、装置以及无线充电装置,可以在满足终端的电池负载功率需求变化的同时,保证为终端进行无线充电效率,且避免了大功率充电过程中终端发热严重情况的发生,适用范围广泛。
