Abstract

The invention relates to a method and device for determining the temperature of a battery, a storage medium and electronic equipment. The method comprises the steps that preset charging parameters corresponding to the battery are acquired; the battery temperature determining step is executed circularly until the temperature difference value between the target real-time battery temperature corresponding to the battery and the preset battery temperature is smaller than or equal to the preset difference value threshold value, and the target real-time battery temperature comprises the preset number of real-time battery temperatures newly determined according to the battery temperature determining step; the preset battery temperature is used for representing the maximum temperature capable of being borne by the battery. That is to say, a plurality of real-time battery temperatures corresponding to the battery can be obtained without performing a long-time charging test on the battery, so that the determination efficiency of the change curve of the battery temperature can be improved, and the charging parameter setting efficiency is improved.

Description

technical field [0001] The present disclosure relates to the technical field of charging, and in particular to a method, device, storage medium and electronic equipment for determining battery temperature. Background technique [0002] At present, there are more and more devices using lithium batteries as energy sources. The charging speed of lithium batteries is an important performance indicator. However, charging too fast will cause the battery to heat up. In the related art, charging parameters are adjusted through a PID (Proportion-Integration-Differential) controller to balance the contradiction between charging speed and battery heating. [0003] How to improve the determination efficiency of the battery temperature becomes an urgent problem to be solved in the charging parameter tuning process of the existing PID controller. Contents of the invention [0004] In order to overcome the problems existing in related technologies, the present disclosure provides a meth...
