Determination of the temperature rise/distribution inside battery-pack allows placement of thermal sensors in locations where the temperature rise is at the highest during operation. In this example, thermal modeling is used for determining such locations in order to minimize design time and ensure product safety and reliability.

Thermal modeling can be used to determine temperature rise and distribution inside a computer battery pack that is providing 50 watts constant power at 45°C ambient.

Comparison of experimental and modeling data are shown, and also the region of interest was temperature of the location around electrical connectors (77°C).
