What are the consequences of excessive battery internal resistance [PDF]

6 FAQs about [What are the consequences of excessive battery internal resistance ]

What happens if a battery has a low internal resistance?

A battery with low internal resistance delivers high current on demand. High resistance causes the battery to heat up and the voltage to drop. The equipment cuts off, leaving energy behind. Lead acid has a very low internal resistance and the battery responds well to high current bursts that last for a few seconds.

What happens if a battery has high resistance?

High resistance causes the battery to heat up and the voltage to drop under load, triggering an early shutdown. Figure 1 illustrates a battery with low internal resistance in the form of a free-flowing tap against a battery with elevated resistance in which the tap is restricted. Low resistance, delivers high current on demand; battery stays cool.

How does heat affect battery resistance?

Sulfation and grid corrosion are the main contributors to the rise of the internal resistance with lead acid. Temperature also affects the resistance; heat lowers it and cold raises it. Heating the battery will momentarily lower the internal resistance to provide extra runtime.

What is the internal resistance of a battery?

The internal resistance of a battery does not consist of the cells alone but also includes the interconnection, fuses, protection circuits and wiring. In most cases these peripherals more than double the internal resistance and can falsify rapid-test methods.

What does resistance mean in a battery?

Measured in milliohms (mΩ), resistance is the gatekeeper of the battery; the lower the resistance, the less restriction the pack encounters. This is especially important in heavy loads such as power tools and electric powertrains. High resistance causes the battery to heat up and the voltage to drop under load, triggering an early shutdown.

What is the internal resistance of a cell phone battery?

The internal resistance varied widely and measured a low 155 mOhm for nickel-cadmium, a high 778 mOhm for nickel-metal-hydride and a moderate 320 mOhm for lithium-ion. These internal resistance readings are typical of aging batteries with these chemistries. Let's now check how the test batteries perform on a cell phone.
