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.
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.
In this paper, a network of 37 fiber Bragg grating (FBG) sensors is proposed for real-time, in situ, and operando multipoint monitoring of the surface temperature distribution on a pack of three prismatic lithium polymer batteries (LiPBs).

In this paper, the quantitative connection of the mapping characteristic vectors between the surface points of and the internal nodes of the battery is characterized by a relevance degree matrix and the internal temperature field is reconstructed directly by way of exploiting the temperature measurements on battery surface.
However, in the presence of a large temperature gradient under high-rate operations, merely using the bulk temperature cannot provide comprehensive information about battery thermal state since the internal temperature gradient cannot be captured and the maximum temperature is likely to be underestimated [99, 100, 106, 110].
Nevertheless, merely relying on these thermal models to monitor the battery thermal state according to the input measurements (i.e., current, voltage, and ambient temperature) has limitations. One of the issues is that such open-loop estimations are susceptible to uncertainties of thermal models, measurements, and initial conditions .
