In addition, temperature measurements are essential to prevent dangerous situations and to maximize the performance and cycle life of batteries.
Monitoring battery temperature is important for Li-ion battery management and can be done accurately and fast using impedance-based temperature estimation. The existing literature predominantly focuses on single battery cells, often under laboratory conditions.
To the best of the knowledge of the authors, there have not yet been any studies that have investigated the applicability of impedance-based temperature estimation to battery packs since the existing literature focuses predominantly on impedance-based temperature estimation for single battery cells, typically under laboratory conditions.
The optimal operating temperature range for these power batteries was found to be between 25–40 °C, and the ideal temperature distribution between batteries in the battery pack should be below 5 °C . Sato pointed out that when the battery temperature is higher than 50 °C, the charging speed, efficiency, and lifespan are reduced.
Contactless temperature monitoring of battery packs during charging using thermal imaging to enable universal chargers that work with batteries from different manufacturers. The thermal imaging sensors are placed near the battery packs to measure their temperatures without contact.
