Numerical study on a preheating method for lithium-ion batteries …
However, the temperature uniformity of the prismatic battery cell heated by wide-line metal film heating methods is very poor [20]. In addition, the safety of preheating system with pure heating elements could be worse than the coupled system combining both heating elements and PCM since the PCM can prevent overheating. Therefore, in this study, we propose a …
