Technical FAQs 4
What is battery internal resistance?
Battery internal resistance is a crucial parameter that determines the performance and efficiency of a battery. It is the measure of opposition to the flow of current within the battery due to various factors such as the electrolyte, electrodes, and connections.
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.
How do you measure DC internal resistance?
DC internal resistance measurement typically employs the current pulse method. The principle is as follows: Apply a constant current pulse to the battery. Record the instantaneous change in battery voltage. R = ΔV / ΔI
How is internal resistance calculated?
The internal resistance is calculated using Ohm’s law: The test current should be low enough such that the voltage drop is less than 10% of the battery’s open circuit voltage. Typically 10-50mA per Ah capacity is appropriate. Pros Cons This test determines internal resistance based on the battery’s runtime under load to a discharge cutoff voltage.
