One can mention the IEC 61960 standard or PNGV (Partnership for a New Generation of Vehicles) procedure for example. Measurement methods for the internal resistance of batteries can be divided up into two categories: DC (Direct Current) techniques and AC (Alternating Current) techniques.
Internal resistance testing is carried out at each process after battery cells are filled with electrolyte and their assembly completed (charge/discharge testing, aging testing, shipping inspections, etc.). There are two methods for measuring internal resistance: the AC method (AC-IR) and the DC method (DC-IR).
Hioki’s battery testers are working at battery manufacturers around the world. The following models are used in internal resistance testing in battery cell production processes. *1: Available to convert the 4-terminal pair measurement of BT4560 to 4-terminal measurement with the conversion plug. *3: Special specification of 0.01 Hz to 10 kHz.
According to IEC61960, t he DC resistance can be measured as follows: A DC current step is applied to measure the change in the cell’s voltage. Battery resistance is defined as the change in voltage over the change in current when a discharge current of 0.2C is applied for 10s followed by a discharge current of 1C for 1s.
