Article Preview

Abstract:

To reduce the influence of heat temperature conditions on performance, reliability and safety of lithium-ion battery pack for pure electric vehicle, and then on the vehicle performance. This article selects the heat temperature field of lithium-ion battery pack as the research object. Firstly, the heat temperature condition of the battery is analyzed , and the distribution of the heat temperature field is determined ; Secondly, the heat model and the heat rate model are set up, and the thermal model of the thermal physical parameters and definite solution conditions are determined; Finally, the heat of battery pack is analyzed by CFD, including using Fluent module in ANSYS software ; Through the simulation analysis of heat temperature field of lithium-ion battery, theoretical guidances of reasonable design to the heat management system are provided.
