Abstract
The objective of the research was to develop and integrate a computerized mathematical simulator of an electrochemical energy storage system into the ELectrically Peaking Hybrid (ELPH) vehicle computing environment. The ELPH simulation package is an interactive computer simulation environment that has been developed for the prediction and evaluation of performance of electric vehicles (EVs) and hybrid electric vehicles (HEVs). A battery simulator was developed that conforms to the ELPH computing environment restrictions and a variety of standards to interface properly with the other vehicular component simulators such as the engine, transmission, power electronics, and motor drive. Numerous historical and published battery models were studied and the most applicable and desirable characteristics were noted in each of them and were used in the development of the simulator. The simulator is based on empirically derived parameters and electrical equations, and employs a voltage time rate of change correction factor for voltage tracking accuracy during small time steps. Simulator results are compared to actual vehicle data acquired in Texas A&M University's Electorsource Horizon-based hybrid electric vehicle. I
