Title (EN) BATTERY LEAKAGE CURRENT DETECTION METHOD, DEVICE AND CIRCUIT
(FR) PROCÉDÉ DE DÉTECTION DE COURANT DE FUITE DE BATTERIE, DISPOSITIF ET CIRCUIT
(ZH) 一种电池漏电流检测方法、装置和电路
Abstract:
(EN) The present invention discloses a battery leakage current detection method, a device and a circuit, relating to the field of batteries, and being used for detecting the leakage current inside batteries. The method comprises: stopping a battery from supplying power for the electronic device when a power adaptor supplies power for an electronic device (S101); obtaining a voltage parameter and a duration parameter (S102), wherein the voltage parameter is the voltage difference of the battery at two different points of time, and the duration parameter is the length of time between two different points of time; and according to the voltage parameter and the duration parameter, determining whether the leakage current parameter of the battery meets a preset condition (S103).
(FR) La présente invention concerne un procédé de détection de courant de fuite de batterie, un dispositif et un circuit, se rapportant au domaine des batteries et utilisés afin de détecter le courant de fuite à l'intérieur de batteries. Le procédé consiste : à interrompre l'alimentation électrique d'un dispositif électronique par une batterie lorsqu'un adaptateur de puissance fournit de l'énergie pour le dispositif électronique (S101) ; à obtenir un paramètre de tension et un paramètre de durée (S102), le paramètre de tension étant la différence de tension de la batterie à deux instants différents et le paramètre de durée étant la durée entre deux instants différents ; et en fonction du paramètre de tension et du paramètre de durée, à déterminer si le paramètre de courant de fuite de la batterie satisfait une condition prédéfinie (S103).
(ZH) 一种电池漏电流检测方法、装置和电路,涉及电池领域,用于对电池内部的漏电流进行检测。该方法包括:当通过电源适配器为电子设备供电时,停止由电池向电子设备供电(S101);获取电压参数和时长参数(S102),其中,电压参数为电池在两个不同时刻的电压差值,时长参数为两个不同时刻的时长;根据电压参数与时长参数,确定电池的漏电参数是否满足预设条件(S103)。
