What does internal resistance mean in a battery?

Internal resistance can be thought of as a measure of the “quality” of a battery cell. A low internal resistance indicates that the battery cell is able to deliver a large current with minimal voltage drop, while a high internal resistance indicates that the battery cell is less able to deliver a large current and experiences a larger voltage drop.

How does internal resistance affect battery voltage?

Effect of internal resistance: According to the formula Terminal Voltage = Open Circuit Voltage − Current × Internal Resistance, when a high current (e.g., during acceleration or startup) flows, the internal resistance causes a voltage drop within the battery.

What happens if the internal resistance of a battery is low?

If the internal resistance of a battery is low, then the battery can deliver higher currents without significant voltage drops. If the internal resistance of a battery is high, then the capacity to carry current is low and the battery shows. In an ideal scenario, a battery would have an internal resistance of zero.

How to measure internal resistance of a battery?

One can mention the IEC 61960 standard or PNGV (Partnership for a New Generation of Vehicles) procedure for example. Measurement methods for the internal resistance of batteries can be divided up into two categories: DC (Direct Current) techniques and AC (Alternating Current) techniques.
