Abstract:With the development of Electric vehicle and related industries, there is a great demand for battery charger. However, the nonlinear characteristics of lithium-ion battery charging increase the complexity of power supply controller design. In this paper, lithium-ion battery model is set up, corresponding parameters are evaluated, and constant current discharge method is adopted. Combining with the model of lithium-ion batteries, small signal model of charger was set up. Furthermore, appropriate charging control strategy and method are proposed. The simulation and experiment show that the system’s control parameters are robust and suitable for lithium-ion system.
