Abstract :
The battery internal resistance as an important indicator of the battery reliability, has been recognized by the experts. Battery back-up power is essential for the safety of the entire power system. Size for accurate measurement of VRLA (Valve-Regulated Lead Acid) battery internal resistance enhanced VRLA battery as a backup power supply reliability article introduces the instrument based on the AD630 precision battery internal resistance measurement through the 4-wire exchange method. Resistance test for two groups of VRLA batteries is to prove its feasibility.This will be an effective alternative to the waste of energy and non-line measurement equipment.
