Thermal management technique is one of the key techniques for the vehicle application of LiMn2O4-based lithium-ion power batteries. A three-dimension thermal model for the battery was established to analyze the influences of current, surface convective heat transfer coefficient and battery cell shell thermal conductivity on the heat dissipation capability of the battery. The investigated results show that the heat dissipation capability of the battery is improved by reducing the working current, increasing surface convective heat transfer coefficient and battery cell shell thermal conductivity;the difference of influences of cases on heat dissipation capability between the metal and the aluminium plastic film is not large.
