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

Cutting-edge power electronic systems today find place in a wide array of industrial applications ranging from personal computers, portable electronic devices, home appliances, automobiles and motor controllers that utilize electric energy for their operation and involve some form of energy processing through a power electronic system
The DC bus voltage is fed by the bidirectional converter from the battery side and it is equal 754 volt in Fig. 13 to feed the 3-phase inverter connected to the Permanent Magnet Synchronous Machines (PMSM)
The hardware in the loop (HIL) results are in good agreement with the initial PSIM simulation
Summary
Cutting-edge power electronic systems today find place in a wide array of industrial applications ranging from personal computers, portable electronic devices, home appliances, automobiles and motor controllers that utilize electric energy for their operation and involve some form of energy processing through a power electronic system. The authors in [20] propose a blended HIL approach for a built test bench for electric vehicles, whereas our enhanced approach uses PSIM at first for evaluation directly links the power circuit of PSIM together with the HIL controller in Typhoon to analyze and compare the results. In the event, both environments give the same set of results, which ensures that the design is verified, and it becomes worthwhile to build by the industry. This is done for several types of electric vehicle to prove the versatility of the proposed models
