Design of Portable Battery Internal Resistance Tester

Shengli Wang

Abstract

The battery internal resistance is an important reference parameter to evaluate the health of battery.This paper presents a method of the lead-acid battery internal resistance measurement based on low AC –current inject method.It introduces the work principle and the process of implementation of this method.Application results show that this system is simple,reliable and costless.
