abstract

We present results of a math-based model of a battery electric vehicle (BEV) designed in MapleSim. This model has the benefits of being described in a physically consistent way using acausal system components. We used a battery model by Chen and Rinćon-Mora to develop a math-based model of a complete battery pack, and developed simple power controller, motor/generator, terrain, and drive-cycle models to test the vehicle under various conditions. The resulting differential equations are simplified symbolically and then simulated numerically to give results that are physically consistent and clearly show the tight coupling between the battery and longitudinal vehicle dynamics.
