model of charging and discharging of the battery is validated experimentally with a traction battery used in EV / HEV. An interesting feature of this model is the simplicity for extracting of the dynamic parameters of technical specifications of the battery. Only two points on the curve for the discharge of the battery in the steady state are required to obtain the necessary parameters. The model of the battery is included in the simulation using the LabJack U12 in the programming environment LabVIEW2012 for EV / HEV applications. The results show that the model can accurately represent the dynamic behavior of the battery during use of EV / HEV vehicles.
