Abstract

This paper proposes an approach to optimize the effect of air-cooling heat dissipation structure for electric vehicle lithium-ion battery pack through CFD simulation and Genetic Algorithm. A 3D model of air-cooling heat system of battery pack is calculated and built through CFD, and the proxy model of battery pack structure parameters and function is established by BP neural network. Then based on this proxy model and genetic algorithm, the three structural parameters with lower maximum temperatures and temperature differences are calculated.
