Dynamic Simulation Model of a Hybrid Electric ATV

Abstract

The application of electric vehicles has its own disadvantages which can influence the critical performance of the vehicles such as the limited capacity of the battery that play a major role in the range of mileage covered. Hence, a hybrid electric All-Terrain-Vehicle (HEATV) is a best solution as the addition of gasoline-powered engine and electric generator can extend the range covered by an electric ATV. In order to determine the effectiveness of the hybrid configuration, a dynamic simulation model need to be developed by Energetic Macroscopic Representation Method (EMR) to analyze the performance of the ATV. The EMR method involve the causal ordering graph and action-reaction principle together with Inversion-based Control to develop a control structure of a HEATV. The simulation test will be run on the original and modifications of the ATV where the original one only depends on EM to drive the vehicle whereas the modified vehicle include the ICE and electric generator for charging process. The simulation results of the original ATV show the decreasing trend in terms of battery state-of-charge. However, after the modifications have been done the battery state-of-charge show the increasing trend and thus, extend the range of mileage covered by an ATV.
