摘要
Abstract
The selection of the open circuit voltage was optimized based on Thevenin model,for the dynamic hystersis characteristics of Ni-MH power battery open circuit voltage.The relationship between open circuit voltage and the historical direction of charging or discharging was optimized on simulation model.Hybrid pulse power characterization test was done on Ni-MH power battery,and RLS was used for model parameter identification.Simulink was used to build classical Thevenin model and the optimized model,and then simulation was done with a input of variable current on the model.The simulation results were shown that the error of average output voltage was 10 mV.For the actual condition of EV,the characteristics of the battery were reflected better by optimized model.关键词
