Abstract

The invention provides a battery internal short circuit judgment method, equipment and electronic equipment. The method comprises the steps that a charge capacity charged into a battery in a preset voltage interval and a discharge capacity used in the preset voltage interval are acquired respectively; and whether the battery has an interval short circuit or not is judged according to the charge capacity and the discharge capacity. According to the battery internal short circuit judgment method, whether the battery has the internal short circuit or not can be effectively judged according to theacquired charge capacity charged into the battery in the preset voltage interval and the acquired discharge capacity used in the preset voltage interval; and meanwhile, the charge capacity and the discharge capacity can be acquired through a voltameter, the electronic equipment is provided with a voltameter inside, and therefore the problem that an application scene is limited can be solved.

Description

technical field [0001] The embodiments of the present application relate to the technical field of battery detection, and in particular to a method, device and electronic device for judging a short circuit in a battery. Background technique [0002] At present, regarding the safety detection method of the battery, it is possible to detect whether the battery has an internal short circuit by monitoring the change of the battery voltage in real time, but this method needs to monitor the change of the battery voltage in real time to detect whether the battery has an internal short circuit, and the application scenarios are limited. Contents of the invention [0003] Embodiments of the present application provide a method, device and electronic device for judging a short circuit in a battery, so as to solve problems in related technologies. [0004] In the first aspect, there is provided a method for judging a short circuit in a battery, comprising: respectively obtaining the ...
