Abstract

The lithium-ion power battery is widely used in energy management system of electric vehicles. Our study proposed an adaptive optimal charge strategy based on multi-objective particle swarm optimization algorithm. The basic principles of multi-objective algorithm are introduced and the physical performance of lithium-ion battery based on different charge mode is discussed. In our research, the internal charge resistance and charge capacity value are analyzed under different charge current. The simulation model of our new method is established and the parameters are calculated. The experiments are operated to verify the influence of the charge stage number, cutoff voltage and inertia weights. The results indicate that our new charge strategy can be applied to the field of grid energy storage and expand the application scope of lithium-ion power battery.
