Battery testers (such as the Hioki 3561, BT3562, BT3563, and BT3554) apply a constant AC current at a measurement frequency of 1 kHz and then calculate the battery's internal resistance based on the voltage value obtained from an AC voltmeter. . This measurement provides valuable insights into a battery's overall condition, its ability to deliver power, and its remaining lifespan. Testing on production lines uses the AC method, which is introduced by this article. When measuring the internal resistance of a battery cell using the AC method, an AC resistance meter. . DC discharge method: By performing instantaneous high current discharge on the battery module, measuring the instantaneous voltage drop on the battery, and then calculating the internal resistance of the battery according to Ohm's law. For example, forcing the battery module to pass a relatively. . 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). R is pure resistance and Z includes reactive elements such as coils and capacitors.
