“…The WPT systems used for the wireless charging can be divided into the following three categories with respect to the state of motion of the EV, With the SWPT, a stationary EV is charged using the WPT. When compared to the plug in wired charger, the SWPT is different only in the wireless transfer of energy [85]. The SWPT is efficient in urban areas where the stations may be installed for EV charging.…”

“…In contrast to conventional CPM designs with a high robustness and stiffness, this paper presents a novel ultrathin CPM design, which allows moderate deflections caused by mechanical bending loads. In this respect, the spatial and functional integration of the transformer components into the plastic composite of the underbody cover combined with the externalization of the power electronics enabled a significant reduction of the z-dimension [6]. The proposed design is schematically illustrated in Figure 6.…”

The functional and spatial integration of a wireless power transfer system (WPTS) into electric vehicles is a challenging task, due to complex multiphysical interactions and strict constraints such as installation space limitations or shielding requirements. This paper presents an electromagnetic–thermal investigation of a novel design approach for an ultrathin onboard receiver unit for a WPTS, comprising the spatial and functional integration of the receiver coil, ferromagnetic sheet and metal mesh wire into a vehicular underbody cover. To supplement the complex design process, two-way coupled electromagnetic–thermal simulation models were developed. This included the systematic and consecutive modelling, as well as experimental validation of the temperature- and frequency-dependent material properties at the component, module and system level. The proposed integral design combined with external power electronics resulted in a module height of only 15mm. The module achieved a power of up to 7.2 kW at a transmission frequency of f0=85kHz with a maximum efficiency of 92% over a transmission distance of 110mm to 160mm. The proposed simulations showed very good consistency with the experimental validation on all levels. Thus, the performed studies provide a significant contribution to coupled electromagnetic and thermal design wireless power transfer systems.

This paper presents a systematic design approach to the development of functionally integrated mechanical-electrical lightweight systems. The development of these systems requires the end-to-end consideration of all product domains involved, aspects of lightweight design and their mutual interdependencies. To manage this complexity, a specialized approach is developed, which extends the V-model of VDI 2206 problem-specific and purpose-oriented. In line with the proposed approach, this work presents the conception and evaluation of three functionally integrated on-board receiver units of automotive wireless power transfer systems for electric vehicles. These concepts provide a significant reduction of the vertical dimensions, which significantly increases the applicability and transferability of wireless power transfer systems.
