Abstract

Modeling the dynamic characteristics of the battery pack for EV during charge and discharge is an important aspect in the modeling for the battery pack. The dynamic characteristics of the Li-ion battery pack´s loaded voltage were analyzed by means of pulsed-charging and pulsed-discharging the battery pack. A mathematic model was produced to describe variation process of the battery pack´s loaded voltage during charge and discharge. Emulations on the simulated operation mode and on the testing of the roadway were carried out. It is showed that the produced model can track the true loaded voltage with small errors and the model can suit the wide and frequent variation of the battery current on the electric vehicle.
