N2 - The performance, life and security of the lithium-ion power batteries used in electric vehicles are closely related to battery temperature, and at present researches pay more attention to cooling rather than heating the batteries. In order to improve the performance of the lithium-ion power batteries at low temperature, simulation and experiments are conducted. The PTC heating method that the single cells are heated by the heating aluminum plate twined by PTC resistance wire is adopted. Firstly, the heating model of battery modules is established in the software of finite element analysis and the results are calculated. Secondly, the experiment is conducted using the PTC method, which shows that this method greatly improves the performance of lithium-ion power batteries at low temperature.
