Battery package performance optimization of side pole impact on electric vehicle
The large deformation of the battery package internal core and cooling system were discovered in the side pole impact analysis of an electric vehicle,and this will have the risk of leakage fire and explosion.The causes were analyzed and the optimization schemes was put forward in this paper.Through the simulation analysis of vehicle collision,the deformation and intrusion of the vehicle is significantly reduced.The deformation intrusion of the battery core and the cooling system is obviously improved,and the force of the battery core and the cooling system is reduced from the original 10.8 kN and 9 kN to 4.8 kN and 3.5 kN,and they have no obvious deformation basically;The risk issue of battery package impact has been improved.
