| High Light | Four-Terminal Battery Internal Resistance Tester ，AC Battery Internal Resistance Tester | ||
This equipment uses a 1kHz AC constant current source and a four-terminal method to measure the AC internal resistance (ACIR) and open-circuit voltage (OCV) of lithium batteries. It boasts an AC impedance resolution as low as 0.1uΩ and excellent anti-interference capabilities.
This equipment is widely used in processes such as cell formation and capacity testing, battery screening for modules/packs, and battery inspection before and after production. It is also extensively used in the battery inspection of high-voltage large modules/packs such as power batteries and energy storage battery cabinets before production.
