This comprehensive guide will demystify the concept of battery internal resistance and provide you with a practical, step-by-step approach to measure it using a common multimeter. . To measure DC internal resistance with a multimeter, you first measure the unloaded voltage of the battery (v1), then the voltage under load (v2), and finally the resistance of the load (r1), which allows you to calculate the internal resistance using ISR = (V1 - V2)/ (V2/R1). This method quickly identifies battery faults, aging, and efficiency by applying a controlled current and measuring voltage drop, ensuring reliable power supply. . In this article, we will demonstrate how to perform DCIR testing using IEST's high-precision charge-discharge equipment in accordance with the IEC61960 international standard, and walk through the actual testing process via software steps. Each analyzer offers unique advantages for pack diagnostics.
