In this paper, a multi-stage TETS charging system of the PNGV model of lithium-ion battery is proposed based on on the analysis of the equivalent circuit model of lithium-ion battery and the existing charging method. Using this system, the charging speed is increasing while the polarization and the temperature rising is suppressed. Taking into account the charging quality of the the lithium-ion battery, the actual charging curve is closer to the optimal charging curve in this system. Combining MATLAB and SIMPLORERMAXWELL multi-platform, the effectiveness of the scheme is verified by joint simulation. The simulation results have theoretical research and practical application value for the establishment of TETS charging system platform for lithium-ion battery.
