Unlike most electronic integrated circuits and microchips in electric vehicles, which operate best at -40˚C to 85˚C or higher, the optimal temperature range for li-ion battery packs is quite narrow and varies depending upon cell supplier, charge and discharge mode and other factors.
Most lithium-ion batteries operate safely between -30°C and 55°C, but pushing beyond that means reduced lifespan, power drops, or worse — thermal runaway. This post breaks down exactly how lithium-ion battery temperature limits affect real-world performance and how you can shop smarter, especially in cold weather.
The temperature difference across the battery pack in a practically significant range of variables was from 2 to 16°С. At the same time, the characteristic temperature exceeded in a number of cases its regulated limit value, which created the risk of the battery’s thermal runaway.
This study performs a numerical analysis of the thermal conditions in a Li-ion battery pack at moderate values of external factors affecting the thermal runaway and typical discharge rates for this type of CCS. Thermal resistance between Li-ion battery and the battery pack case was found to greatly reduce heat exchange with the environment.
Thus, it can be concluded that in the natural convection mode with heat exchange rate close to maximum possible (α = 10 W m –1 K –1), elevated ambient temperature creates conditions for thermal runaway of the lithium battery due to its thermal resistance (technological air gap) that reduces the battery heat exchange with the environment.
