In this paper, a methodology for improving vehicle-level radiated electromagnetic interference (EMI) in electric vehicle (EV) is proposed. This methodology predicts vehicle-level radiated EMI by using the multiport network theory, based on analyzing the contribution from each electronic component to find out the main EMI source. To validate its effectiveness, the proposed methodology is applied in an actual EV for low-frequency radiated emissions. Simulation in a commercially available electromagnetics software and measurement in the EV are combined to predict the vehicle-level emissions, and then the electronic component with the greatest EMI that causes failure to meet the EMC standard is identified. After improving this component, the vehicle-level radiated emission is reduced to comply with the EMC standard, proving that the presented numerical method is effective. The proposed methodology can also be used in other EMC issues, regardless of the amount of interference sources and sensitive equipment.

The popularity of the electric vehicle (EV) brings us many challenges of electromagnetic compatibility (EMC). Automotive manufacturers are obliged to keep their products in compliance with EMC regulations. However, the EV is a complex system composed of various electromagnetic interferences (EMI), sensitive equipment and complicated coupling paths, which pose great challenges to the efficient troubleshooting of EMC problems. This paper presents an electromagnetic topology (EMT) based model and analysis method for vehicle-level EMI prediction, which decomposes an EV into multi-subsystems and transforms electromagnetic coupling paths into network parameters. This way, each part could be modelled separately with different technologies and vehicle-level EMI was able to be predicted by algebra calculations. The effectiveness of the proposed method was validated by comparing predicted vehicle-radiated emissions at low frequency with experimental results, and application to the troubleshooting of emission problems.

This paper describes the development and validation of a control-oriented drivability model for a power-split hybrid-electric vehicle (HEV). The HEV model is capable of identifying drivability issues under critical conditions such as pedal tip-in tip-out, change of operating modes, and gear shifting. The model is useful for the design, improvement and calibration of control strategies. The model is implemented in Simulink® and is validated using data collected from a test vehicle.


In this paper a SEPIC-ZETA power factor correction converter is introduced with fuzzy control for better performance. The controller of the converter is updated with 49 rule base fuzzy interface system with 7 membership functions in each input variable. The novel proposed converter operating modes are observed with change in switching states. For application a three-phase induction machine with inverter is connected to the proposed circuit. The characteristics of the converter and the machine are studied using MATLAB Simulink environment.

Abstract This paper describes the development of the Low Storage Requirement (LSR) Hybrid Electric Vehicle (HEV) Vehicle System Controller (VSC). It defines the LSR configuration and discusses the advantages of this particular configuration. The main focus of this paper is the hybrid operating strategy for this vehicle and the details of the hybrid operating modes. This hybrid vehicle was developed as a part of the U. S. Department of Energy (DOE) Hybrid Propulsion Systems Development Program that was conducted under a cost-shared subcontract funded equally by Ford and DOE through the Midwest Research Institute which manages and operates DOE’s National Renewable Energy Laboratory in Golden, CO.
