A Novel Asymmetrical Quadrupolar Coil for Interoperability of Unipolar, Bipolar, and Quadrupolar Coils in Electric Vehicle Wireless Charging Systems

The unipolar, bipolar, and quadrupolar coils used in an electric vehicle wireless charging system are not interoperable with each other. Thus, there would be interoperability issues when the transmitting and receiving coils are not the same. To solve this issue, this letter proposes an asymmetrical quadrupolar coil that can be interoperable with the four conventional coils at the same position for efficient wireless power transfer, namely the unipolar coil, the bipolar coil along two perpendicular directions, and the quadrupolar coil. Large coupling coefficients can be achieved for the proposed coil with the four conventional coils when perfectly aligned. The misalignment performance with the four conventional coils is also investigated. An experimental prototype is developed to compare the conventional symmetrical quadrupolar coil and the proposed asymmetrical quadrupolar coil for validation of interoperability. The proposed asymmetrical quadrupolar coil achieves a maximum coupling coefficient of over 0.10 and a maximum dc-dc efficiency of over 85% with the four conventional coils.

Automation in electric vehicle futures

In this article we consider how people will live with the automated features of electric vehicles (EVs) in possible futures. We complicate dominant industry and government narratives which: envisage EVs as part of future fully automated systems - involving remote or wireless EV charging, vehicle-to-grid and vehicle-to-home electricity systems; and see these moves as driving a transition to decarbonisation, renewable energy and environmental sustainability and planetary health. We argue instead that the roles of automation in people’s everyday lives with EVs in the present and possible futures are shaped by the particularities of life itself, and the places and localities in which it is experienced. Our research shows that how people live with automation is likely to pivot on everyday values of care and safety, and implies a future life where people remain in control of automated features, rather than signing up for fully automated systems. To understand the future of EV automation therefore, we must look to how people navigate such values and how they apply everyday creativity and innovation in possible, future contingent circumstances. To develop this we draw on our analysis of industry materials, online ethnography, documentary filmmaking and futures workshops.

Inner Resonance and Outer Current Based Control Strategy for Inductive Power Transfer System Used in Wireless Charging for Electric Vehicles

The wireless charging for electric vehicle is getting popular due to the absence of sophisticated cable connection and associated issues with the actuators in field for connected charging. The major challenges in inductive power transfer (IPT) systems are the control of the resonance converter and synchronisation in communications with the vehicle and power supply. In IPT system, the dynamic nature of load as well as system demands extra care for the existing charging architectures. This work proposes a unique control algorithm to charge the Li-ion battery under coupling coefficient and load variations. The developed control algorithm is validated in MATLAB simscape platform. Further, the control logic is validated using the Texas C2000 Delfino controller in 1 kW IPT system.

New-generation electronic appliances and cardiac implantable electronic devices: a systematic literature review of mechanisms and in vivo studies.

Cardiac implantable electronic device (CIED) functions are susceptible to electromagnetic interference (EMI) from electromagnetic fields (EMF). Data on EMI risks from new-generation electronic appliances (EA) are limited. We performed a systematic literature review on the mechanisms of EMI, current evidence, and recently published trials evaluating the effect of EMF on CIEDs from electric vehicles (EV), smartphone, and smartwatch technology and summarize its safety data. Electronic databases, including PubMed and EMBASE, were searched for in vivo studies evaluating EMF strength and incidence between CIEDs and commercial EVs, new-generation smartphones, and new-generation smartwatches. A total of ten studies (three on EVs, five on smartphones, one on smartphones, one on smartphones and smartwatches) were included in our systematic review. There was no report of EMI incidence associated with EVs or smartwatches. Magnet-containing smartphones (iPhone 12) can cause EMI when placed directly over CIEDs - thereby triggering the magnet mode; otherwise, no report of EMI was observed with other positions or smartphone models. Current evidence suggests CIED recipients are safe from general interaction with EVs/HEVs, smartphones, and smartwatches. Strictly, results may only be applied to commercial brands or models tested in the published studies. There is limited data on EMI risk from EVs wireless charging and smartphones with MagSafe technology.

Analysis and experimental verification of efficiency parameters affecting inductively coupled wireless power transfer systems

Wireless power transfer (WPT) provides a safe and independent transfer of energy without the constraints of cables. The most suitable method for wireless charging of Electric Vehicles (EVs) is magnetic resonance coupling, which transfers energy in the near field. In this study, the effect of quality factor on the wireless charging system of an EV is investigated. After determining 85 kHz frequency, 20 kW power and 150 mm inter-coil distance, the design of the WPT system was realised according to the quality factor. It was observed that the quality factor affects the efficiency, critical air gap and voltage stress on capacitors. As the quality factor increases, the critical air gap increases and longer distances can be transmitted efficiently. However, as this factor increases, the voltage stress on the capacitors also increases. In this study, the critical air gap was determined according to the quality factor. Although high quality factor increases efficiency at high air gaps, it decreases efficiency in applications where air gaps are close. In fact, increasing the quality factor by increasing the inductance means increasing the internal resistance and this has been observed to reduce the maximum efficiency. In this study, the effects of Q factor on transmission power and transmission efficiency are investigated through experimental study and simulation.

A Dual-Band Coil Array With Novel High-Order Circuit Compensation for Shielding Design in EV Wireless Charging System

For the wireless power transfer (WPT) system in electric vehicle (EV) applications, a serious concern lies in the leakage electromagnetic field (EMF) emission. In order to address this issue, this article presents a dual-band coil array (DB-CA) with novel high-order circuit (HOC) compensation. The most attractive feature of DB-CA is that both the first and third harmonics of leakage EMF can be reduced simultaneously, while the system still resonates at the same frequency. A detailed mathematical model is established to intuitively reveal the relevance between impedance design and shielding performance, as well as the constraints to achieve resonance. In addition, the novel HOC compensation is employed to decouple the shielding design at each harmonic. Both simulated and experimental results verify the effectiveness of DB-CA, and a 1-kW WPT prototype operating at 85 kHz is established. By applying DB-CA, the leakage EMF can be reduced by 3.88 dB at 85 kHz and 1.84 dB at 255 kHz, respectively. Meanwhile, the system resonant frequency still locates at 85 kHz, and the achieved zero phase angle condition is independent with load condition. It can provide significant guidance to the design of shielding configurations in EV Wireless Charging System.
