Numerical study on a preheating method for lithium-ion batteries
It shows that Heating Mode II achieves a larger heat-up rate but a much worse temperature uniformity of the battery cell than Heating Mode I. During the process of heating up the battery from 253.15 K to 283.15 K, the temperature difference over the battery cell is as large as 30 K for Heating Mode II, while it is within 6 K for Heating Mode I.
