Abstract
This paper presents an Electric Vehicle simulator to aid in Electric Vehicle Education. There has been an exponential surge in demand for developing new generation of vehicles using electric-technology. That has caused rapid shift in design paradigm from mechanical to electrical. Such a paradigm shift requires developing new technology educational programs in electric vehicles. The EV-simulator presented in this paper will be helpful for such programs. The simulator is written in Visual C++/MS Visual Studio .NET 2007. It is called LAMAR-EVSim1 after Lamar's first Electric Vehicle Lamar-EV1. The tool is primarily tailored for educational use. Input data to the simulator is presented through a set of input data files including specifications of: the vehicle, the electric-elements, and the environment. The simulator estimates output parameters hierarchically from the tire, gear-box, motor, battery-pack, and finally at vehicle-level. The estimated output parameters include: various drag forces, torques, currents, voltages, RPMs, powers, top speeds, and mileages. Unlike other ev-simulators, this simulator embeds dynamic equations & algorithms context-sensitively so that the output simulation trace are self-instructive.
