Document Type and Number:
WIPO Patent Application WO/2018/120407
Kind Code:
A1
Abstract:
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).
