Looking at the future passenger car market and the competition of vehicle technologies and fuels to reach European corporate fleet CO2-targets, total costs of ownership (TCO) are certainly an important indicator for customer acceptance, especially in the case of BEVs and PHEVs. With Vector21 (Vehicles Technologies Scenario Model), DLR started in 2007 with agent-based vehicle choice modeling. We will compare TCO with a more recent, utility based approach and we will give insight to scenario results for the German market.

In every electrification program, traction motor efficiency is paramount. Efficiency of electrical energy use is usually what is most discussed; however, there is another form of efficiency that is quite important: power density. This efficiency is carried out by maximizing performance and minimizing volume and weight. There are many aspects that impact power density. This presentation will investigate what the main drivers of power density. Designers will learn how voltage and/or current, cooling, winding selection and rotor speed can all impact electric motor performance. If the vehicle designer understands how these relate to one another and the impact they have on electric motor/generator performance, one can optimize and select the rest of the components in the powertrain to maximize power densities to reduce costs.

Current and angle sensors considerably influence the performance of electric drives. The sensors need to be safe and have limitations like limited bandwidth and signal processing delay times. Depending on the operating point, however, these effects may be more or less severe and have different effects, like torque ripple or lower efficiency. The presentation shows requirements, the impact and compensation methods for sensors parameters.

For a widespread adoption of Electric and Hybrid vehicles, a robust and convenient charging method is necessary. Economic cars in the near future will have limited electric driving range, and therefore will need frequent charging. Therefore, wireless automated charging will be most suitable for the widespread acceptance of electric and plug-in hybrid cars.

With the rising cost of semiconductors and limited space for power inverters in electric and hybrid vehicle applications, the demand for efficient power electronics is increasing. Greater efficiency has a direct impact on the required size of both the surface area of the semiconductors and the cooling system. Power electronics efficiency also has a great impact on other powertrain components like the battery capacity further increasing the need for higher efficiency. This presentation discusses the different solutions used today that allows improved IGBT switching losses and expresses the limitations of these solutions. The new Reflex Gate Driver Technology is presented with description on how it can significantly improve IGBT switching losses. Reflex gate driver technology allows up to twice as much output current from the same IGBT die surface area. Additional improvements are presented like the use of variable switching frequency and optimized control algorithms for better energy management.

The success of electric mobility is not only determined by the performance of the vehicles. From a customer perspective, the certainty to always be able to recharge the battery (private or public) is important. Solving the charging infrastructure issues turns out to be almost as challenging, since a vehicle is parked at very different locations during the course of a day and the still limited range requires more charging events. Different technical environments and customer expectations require very different solutions – from a basic cable with limited power and functionality to a fast charger with permanent communication skills between vehicle and grid. Based on our experience from multiple projects we will give an overview of the current situation in electric vehicle charging, describe the key challenges and provide insights for a successful way forward.
