    Battery cabinet power and internal resistance test

    Although batteries' internal resistance would ideally be zero, internal resistance exists due to a variety of factors. Internal resistance increases as a battery degrades. On battery. 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). Testing on production lines uses the AC method, which is introduced.
