6 FAQs about [Lithium battery hot and cold detection]

Why is the temperature of a lithium-ion battery important?

The temperature of the lithium-ion battery is a crucial measurement during usage for better operation, safety and health of the battery.

How can surface temperature imaging be used to diagnose lithium ion?

The use of surface temperature imaging to determine the thermal state of lithium-ion can serve as a supplement to existing diagnostic methods. Machine learning algorithms can automatically process large amounts of data and adaptively adjust them by analyzing the relationships between the data, which is applied in the field of batteries.

Is temperature a critical internal state of a lithium ion battery?

Existing literature attempts to include temperature as one of the critical internal states of LIBs and referred to it as the state of temperature (SOT) in order to reflect the thermal state of batteries [57, 59, 60]. However, there is no clear specification about which temperature value should be used as the SOT.

Do lithium-ion batteries have thermal behavior?

A profound understanding of the thermal behaviors exhibited by lithium-ion batteries, along with the implementation of advanced temperature control strategies for battery packs, remains a critical pursuit.

How does a lithium battery affect the temperature zone?

Jilte et al. observed that the localized temperature zone within lithium battery cells is influenced by the module’s position. In certain specific areas of the battery, temperature increases of up to 7 degrees Celsius were recorded, leading to the formation of a temperature gradient and compromising thermal uniformity within the battery cell.

Why do lithium ion batteries need a real-time electrode temperature monitoring?

Temperature rise in Lithium-ion batteries (LIBs) due to solid electrolyte interfaces breakdown, uncontrollable exothermic reactions in electrodes and Joule heating can result in the catastrophic failures such as thermal runaway, which is calling for reliable real-time electrode temperature monitoring.
