Summary form only given, as follows. This panel will discuss the importance of close collaboration between suppliers and automotive OEMs to develop successful electric vehicles. Some of the aspects that will be discussed in this panel include: Electrified Propulsion Vehicle Requirements; Electrified Powertrain Architecture; Regulations; Torque Security, Vehicle Safety, Communication (V2V, V2I), Entertainment...
In this paper, the control of the inverter output current for the wireless power transfer system that responds to the load changes is presented. The wireless power transfer system is composed of the high frequency inverter for power conversion, power cable on the ground, and on-board pick-up to produce the power by electro motive force that reacts to the magnetic field of the power cable on the ground...
Reliability of Power inverter in an Electric Vehicle is of great importance as it is one of the most critical components of the electric powertrain. The failure rate prediction model (parts count method) is utilized to calculate reliability of Power inverter topologies. It is found that paralleling the switching devices increases the reliability of the Power inverter but the reliability saturates...
This paper presents the design, transient finite element analysis, and prototyping of a line start permanent magnet motor in two cases: with solid rotor, and with a composite rotor. In the composite rotor, the solid rotor is coated with a thin layer of copper. The thickness of the thin layer of copper is about 0.05 mm. Results of finite element analysis show that with the composite rotor, both starting...
In order to be aligned with new emission standards for heavy duty transportation systems, there is a strong demand for alternative fuel buses. Pure electric buses are a possible solution; however, due to the average daily range requirement of 120–140 miles per day, the battery systems required for such vehicles significantly reduce its performance and increase its costs. One method to address this...
Most experts foresee more demand for electric and plug-in electric vehicles. This demand is triggered by environmental concerns, energy dependency, and unstable fuel prices. Available vehicle routing algorithms are designed for fossil-fuelled vehicles. These algorithms optimize for the shortest distance or the shortest travel time between 2 points. Dijkstra or Dijkstra-like algorithms are mostly used...
Due to marketability issues of the Hybrid Electric Vehicle (HEV) compared to the conventional vehicle, simultaneously optimizing the energy storage system (ESS) cost-a main contributor to overall cost- and Fuel Economy (FE) of the HEV is necessary. A Pareto Frontier of ESS cost and FE is a valuable design information which offers entire optimum designs, proportional to the customer requirements. The...
This manuscript presents a powertrain model with two propulsion machines and a battery-ultracapacitor based hybrid energy storage system (HESS). A two-propulsion machine powertrain can take the best advantage of the limited space under the hood of high performance electric vehicles. One of the major challenges in this architecture is to effectively split the load power demand between the two propulsion...
Electric vehicles are gaining more popularity. Governments from both developed countries and of high-pollution developing countries are pushing towards more research for such vehicles. Marked by their zero carbon footprints, environmental groups strongly support these vehicles. For these reasons sales have been increasing steadily in the past few years. Due to that fact that it's still a new field,...
University of Michigan, Dearborn (UMD) and Underwriters Laboratories (UL) LLC have partnered to help further the commercialization of safe and reliable EV wireless charging technology. In this work, the optimized design of a 3.3 kW wireless EV charger is introduced. The predictive modeling is used as a tool for analyzing the system power sensitivity in terms of the horizontal misalignment. The modeling...
