Abstract: Required
by electric vehicle system simulation, two equivalent circuit battery
models named GNL model and CR model are proposed. To validate these two
models, a comparison study between five models including another three
often used models named Rint model, Thevenin model and PNGV model are
conducted. Model parameters of five models are all obtained by
performing a multiple linear regression on the hybrid pulse test data of
an 80 Ah Ni-MH battery pack with 320 cells in series. Current input
models in vehicle simulation environment of these five models are
realized by MATLAB/ Simulink with the obtained model parameters. A 26.67
A constant current discharge test and a 1 372 s FUDS test are used to
validate and compare models’ performance. Compared with voltage error
between simulation result and test data, it is concluded that PNGV model
and GNL model are more suitable for electrical vehicle system simulation
and GNL model done better.
