GENERIC BATTERY MODEL FOR ELECTRIC AND HYBRID VEHICLE SIMULATION PERFORMANCE PREDICTION.

The importance of battery models for predicting Electric and Hybrid Vehicle (EHV) performance is pointed out. The term ″generic″ is described as it pertains to battery models and computer simulation. A battery polynomial equation is formulated that provides the main hypothesis for several generic battery models. Temperature compensation is factored into the polynomial and the baseline fractional utilization battery model is explained. The JPL/PURDUE model, used in the DOE funded ELVEC EHV Computer Simulation Program is described. This model is a generic modification of an algorithm developed at Purdue University. The relationship between this model and the fractional utilization model is illustrated, and the accuracy of the model is compared to actual vehicle and laboratory tests.
