Abstract:

In recent years, due to the rapid increase in the number of vehicles in the world, the traditional vehicles using gasoline or diesel as energy have led to serious air pollution and energy depletion. It is urgent to develop practical clean energy vehicles. The performance of electric vehicle depends on the power battery pack. The working temperature of the battery pack has a great impact on the performance of the battery, so it is necessary to carry out thermal management on the battery pack. Taking a lithium-ion battery as the research object, the temperature field of the battery pack in the charge and discharge state is simulated and analyzed by using CFD simulation software in the way of air cooled heat dissipation, so as to understand the influencing factors of uneven temperature field. At the same time, the development trend of battery temperature can be well predicted through simulation, so as to provide theoretical basis for the design of battery pack.
