6 Frequently Asked Questions about “Battery cabinet power and internal resistance test”
What is battery internal resistance?
Battery internal resistance is a critical performance parameter that determines the runtime, power delivery, current capabilities, efficiency and health of a battery. Measuring the internal resistance allows you to analyze battery characteristics and performance for design optimization, production testing or periodic maintenance.
Can internal resistance tests tell us anything about battery capacity?
However, the internal resistance tests cannot tell us everything regarding battery capability or condition. Low capacity cells can be identified, but absolute predictions regarding the cell capacity are more difficult to make. Some points to consider are:
What is internal resistance testing?
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).
How to measure battery internal resistance?
The pulse load test is another method for measuring battery internal resistance. It involves applying a short-duration, high-current pulse to the battery and measuring the voltage response. The internal resistance can be calculated from the voltage drop during the pulse. 1.
