Summary:

Model based development is an approach pursued to obtain an advanced insight into powertrain and vehicle development. This approach enables the ability to trace errors early on, thereby reducing the dependence on field testing and saving cost and time involved in the development process. The purpose of this study is to develop a system level battery electric vehicle model using GT-Suite as modeling platform, for Light Heavy Duty applications. The outcome of this study is electric range estimation, performance analysis, component sizing and optimization for inverter-motor and battery components. The model has been developed using a map-based approach. Hence, the simulation time is faster than real-time, requires less input data and can be used for preliminary range and performance estimation. The model fidelity has been validated against performance, acceleration, deceleration and coast-down data obtained from field testing. Apart from field data, standard EPA drive cycles and customer usage based drive cycles have been used as target to the model. Energy efficiency (Wh/mile) and MPGe calculations have been performed as part of model validation. The applications of this study are to observe and study the effect of parameters such as motor power, air conditioning, battery capacity et cetera on range and performance
