Hardware-in-the-Loop Validation of Different Power Train Topologies’ Models in Electric Vehicles: A Plug-and-Play Capability

Abstract

This study presents a novel modelling methodology for electric vehicle power train. This covers both Front Wheel and all-wheel drives. The simulation is built in PSIM and verified in Typhoon's hardware in the loop (HIL) solution. HIL technology is used for real time verification. The approach is highly attractive due to characteristics of rapid prototyping which allows quick and easy adjustment in simulation in real time. Thus, avoiding the high costs associated with physical prototypes. The paper presents results (dynamic responses of various vehicle components) and the effects of adjusting various vehicle parameters. The results obtained from simulation is successfully verified in the HIL platform. The result from this study proves the robustness of the simulation and HIL model and control algorithms. This methodology saves costs and lead time to build and design a physical hardware. Additionally, the results from the modeled vehicles agree with data provided by the manufacturer. Finally, the design is simulated in a modular way such that they can be used for various propulsion setups and schemes
