Improving temperature monitoring of a battery pack for electric vehicles to quickly and accurately detect and locate temperature increases in individual cells. The solution is using a common infrared matrix sensor positioned near the cells with a view encompassing the cell surfaces. This allows capturing thermal images of the cells.
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.
Early detection of thermal events in battery cells of an electric vehicle to prevent propagation and mitigate thermal runaway. The method uses optical pyrometers inside the battery module to detect increased shortwave radiation emitted by a cell reaching a critical temperature.
During vehicle operation, the initial battery state and first operational data are used along with the model to estimate the internal temperature. Feedback corrections are made to improve accuracy. This allows estimating the battery's internal temperature in real-time when external sensors fail.
The longer-term implications of embedding instrumentation within a battery are also evaluated with cell performance evaluated after a period of calendar and cyclic ageing. Our study demonstrates the importance of internal temperature monitoring during cell operation by comparing internal and surface temperatures measurements.
