How do batteries control temperature and current [PDF]

6 FAQs about [How do batteries control temperature and current]

How does temperature affect battery power?

For example, the heat generation inside the LIBs is correlated with the internal resistance. The increase of the internal temperature can lead to the drop of the battery resistance, and in turn affect the heat generation. The change of resistance will also affect the battery power.

Why is it important to control battery temperature?

As the battery voltage continues to drop under constant power conditions, the battery current output will accordingly increase, which brings a risk of thermal runaway in instances of weak heat dissipation. Therefore, knowing how to control the battery temperature is very critical for safe use.

What is battery temperature?

The battery temperature refers to the process of heating on the battery surface due to internal chemical and electrochemical changes, electron migration, and material transfer during the use of the battery, which is a normal phenomenon.

How does temperature affect the performance of a battery pack?

The high temperature will accelerate the process of an electrochemical reaction to the battery while the low one causes the opposite result. The temperature difference between battery packs will disrupt the consistency of battery packs and affect their performance.

How to monitor the temperature of a battery?

It is particularly important to monitor the temperature for the efficient management of the batteries. Various temperature indication methods are proposed . Using the sensors (thermocouples, etc.) mounted on the battery surface or tab to measure the temperature is the most straightforward.

Why is the temperature distribution in a battery uniform?

The temperature distribution inside the battery is uniform. In order to reduce the complexity of battery modeling and simulation time, this work ignores the temperature difference at different positions inside the battery, referring to a lumped-parameter thermal model. The resistance of wires in the battery pack is ignored.
