Abstract

The disclosure provides a method and a device for detecting a DC resistance of a battery, electronic equipment and a computer storage medium. A transduction process of the battery comprises a first transduction stage and a second transduction stage which are continuous, and the method comprises the steps of: acquiring a first transduction current of the battery in the first transduction stage; acquiring a first voltage of the battery when the first transduction stage is switched to the second transduction stage; acquiring a second transduction current of the battery in the second transductionstage; acquiring a second voltage of the battery when a first preset duration is reached after entering of the second transduction stage; and determining a DC resistance of the battery according to adifference value between the first voltage and the second voltage as well as a difference value between the first transduction current and the second transduction current. The method of the disclosureis capable of achieving detection of a DC resistance of a battery in a continuous transduction process of the battery.

Description

technical field [0001] The present disclosure relates to the field of electronic equipment, and in particular to a method and device for detecting DC impedance of a battery, electronic equipment, and a computer storage medium. Background technique [0002] DC impedance is a very important parameter related to the charging and discharging process of lithium-ion batteries, which mainly includes ohmic impedance and polarization impedance during battery operation. Due to the uncertainty of the polarization impedance, the polarization impedance fluctuates greatly with the charge and discharge of the battery, so it is difficult to measure the DC impedance. [0003] At present, there is no way to monitor the DC impedance in real time. Most of them control the intermittent charging of the electronic equipment, that is, the electronic equipment needs to be stopped charging during the charging process to meet the measurement conditions of the DC impedance. However, the way of intermi...
