- Dynamic Charging, meaning supplying electric energy to electric vehicles while moving and also referred to as Electric Road Systems (ERS), can be implemented in a number of different ways. In Sweden, no less than four different technologies are being developed and/or demonstrated. This is, in an international comparison, unique. This paper represents an effort to describe these different technologies and their known and expected properties.

- Electric Road Systems (ERS) are analysed here as a feasible solution for the electrification of heavy traffic, where the predominant approach for passenger cars based only on batteries and a network of fast-charging stations combined with slower overnight charging becomes unrealistic due to the large amount of batteries required. Nonetheless, this study shows that in most cases, building such ERS so that they can be used by both types of vehicles results in added value to society.

- A mild hybrid electric-diesel powertrain for personal vehicles is modeled with respect to longitudinal vehicle dynamics in real-world recorded drive cycles. The potential in terms of fuel consumption reduction in an ideal P0 and P2 mild hybrid electric system is evaluated in order to define the outer boundaries of how much the hybrid topologies can offer. The results are compared with logged data from real-world driving with a prototype vehicle in rural/highway and city drive cycles. The near-ideal powertrain model based simulations offer higher fuel consumption reductions than the prototype vehicle due to the ability of aggressively shutting off the combustion engine during low power requests. The largest reduction of fuel consumption calculated is 41% for a P2 configuration in city driving with a micro hybrid topology as reference. While quantifying the potential gains from an ideal P2 system, the resulting load profile for the traction assist electric machine is also extracted, giving valuable information for the detailed design process of a such machine. Fast cranking of the combustion engine is a key feature for mild hybrids, torque and energy requirements for this procedure is quantified: 1.1 kJ is needed in a 300 ms time window, which is also verified by measurements.
