Abstract :
With excellent performance, LiFePO4 cathode material for lithium ion batteries attracts more and more attention on HEVs. In this paper, the dynamic characteristics of the batteries are investigated over different current profiles. A dynamic equivalent circuit model is proposed to describe the dynamic characteristics of the batteries. Simulation results over different tests show the dynamic equivalent circuit model can represent the output characteristic of the batteries accurately.
