6 FAQs about [Energy storage battery internal resistance test]

Why is it important to measure internal resistance of a battery?

This heat not only represents energy wastage but also contributes to the degradation of the battery. The first reason for measuring internal resistance is to ensure quality control throughout production. It is possible to determine the quality of a battery by measuring its internal resistance.

What should a battery's internal resistance be?

Ideally, a battery's internal resistance should be zero, allowing for maximum current flow without any energy loss. In reality, however, as illustrated in Fig.1, internal resistance is always present. Let's consider an example to illustrate this. The battery voltage is determined by the internal resistance and the output current.

What does internal resistance mean in a battery?

Internal resistance is one of the parameters that indicate a battery's ability to carry current. When the value of internal resistance is low, the battery is able to carry a significant amount of current. On the other hand, a battery with high internal resistance can only carry a small amount of current.

Why is internal resistance important in battery management system (BMS)?
