Method to Support Lithium-Ion Batteries' Operation at Low Temperatures

A method for supporting the operation of 18650 lithium - ion batteries at low temperatures is presented. The developed method is applicable to other types of lithium-ion batteries, providing the same power for electric heating of all batteries in a battery pack. The results showed that the developed heating method ensures the lithium-ion batteries to reach in just a few minutes the recommended temperature range for their safe operation, even at very low $\mathbf{(below~ \text{-}20^{\circ}C)}$ ambient temperatures.
