Special Issue Information

Dear Colleagues,

Wireless power transfer (WPT) systems are one of the most promising electric vehicle (EV) charging technologies that can improve the overall charging process and also reduce the on-board battery systems required. Improving the overall battery charging process is very important and could happen by making it more user-friendly and by reducing the charging process and time in an innovative way, i.e., via static, stationary, and dynamic wireless power transfer concepts for electromobility. Technical solutions impact vehicle and grid side (EVSE) power electronics and control, materials, and energy use, magnetic coupling and mechatronics aspects, application performance and charging management strategies (e.g., for a fleet of electric buses), on-board energy storage requirements, cost and business models, vehicle–grid communication, smart-grid integration, etc.

This Special Issue is focused on the recent advances in wireless/inductive power transfer systems for electric vehicles that address the newest developments and go beyond the state of the art. Prospective authors are invited to submit original contributions/articles for review and for possible publication in this Special Issue. Topics of interest include (but are not limited to):

  • Wireless power transfer systems for EVs and PHEVs
  • Architecture optimization of EVs with WPT charging/powering
  • Modular power electronics for optimized charging systems
  • Novel WPT coupling concepts
  • WPT charging infrastructure
  • WPT coil design and magnetics
  • Emerging power electronics interfaces and their control algorithms
  • Multiple energy sources for EVs, including WPT
  • Energy management strategies for WPT EV
  • Design optimization for WPT for EVs
  • WPT vehicle energy storage optimization
  • WPT vehicle fleet use and management optimization
  • Vehicle-to-grid (V2G), vehicle-to-home (V2H), Grid-to-vehicle (G2V) with WPT
  • Environmental and socio-economical aspects of WPT electromobility (LCA, TCO)

This paper presents a thermal investigation of lightweight on-board receiver modules of wireless power transfer systems for electric vehicles. The studied modules are capable of receiving up to 11 kW at a resonance frequency of 85 kHz over a distance of 110–160 mm. The receiver modules were built as sandwich and space–frame concept to design stiff and lightweight structures. The high transmission power of automotive wireless power transfer systems combined with the multi-part assembly of receiver modules led to challenges in heat management. To address this, the physical behaviour of the proposed lightweight concepts were studied on component and system level using a hardware-in-the-loop testing facility for wireless power transfer systems. Special emphasis was laid on the validation of a thermal simulation model, which uses analytical calculated power losses taking into account their temperature dependency. The proposed simulation model is consistent with the experimental validation of the critical active components. The performed systematic studies build the basis for a more sophisticated thermal dimensioning of various constructions for wireless power transfer modules. Full article

This paper presents a novel inductive link for wireless power transfer (WPT) system of electric vehicles (EVs). The WPT technology uses an alternating magnetic field to transfer electric power through space. The use of the WPT technology for charging electric vehicle provides an excellent alternative to the existing plug-in charging technology. It has been reported that the inductive link using planar coils such as the circular and rectangular coil are capable of transferring a high power with high efficiency. However, they have a poor tolerance for lateral misalignment, thus their power transfer efficiency decreases significantly with the misalignment. Due to the poor misalignment performance of the planar coil topology, extensive studies have been carried out on the flux pipe topology due to their excellent misalignment tolerance. To address this, in this paper, a novel inductive link using double helix flux pipe topology is proposed. The performances of the inductive link using the proposed double helix flux pipe are analyzed and compared with inductive links using conventional flux pipe. The proposed model has excellent characteristics in terms of the power transfer efficiency and tolerance against misalignments. The proposed model is capable of transferring over 1.6 kW of power with a coil-to-coil efficiency of over 98.5% at a load resistance of 20 Ω. Full article

The main barriers to the wide acceptance of electric vehicles, such as the limited driving range or the high acquisition costs, are to be countered by various technology alternatives for the powertrain of the future. Promising developments include improved battery technologies, fuel cell technologies or a constant power supply of the vehicle while driving, for example through dynamic inductive charging. In this context, a holistic technology comparison would contribute to a comprehensive and understandable information situation by making the heterogeneous technological concepts comparable with regard to different evaluation criteria. Therefore, this work describes the basic assumptions of the proposed holistic comparison of alternative powertrain technologies for long-distance mobility. Relevant framework conditions are structured and a procedure for the evaluation of infrastructure expenditures is shown. Building on this, a selection of key performance indicators is defined and explained. The proposed KPI framework is applied to a passenger car in the economic area Germany. The results show that by using electrified roadways, ecological as well as economic advantages against other alternative powertrain designs can be derived. Full article
