In wireless electric vehicle charging systems, misalignments between ground-assembled transmitter and vehicle-assembled receiver are undesirable but inevitable, which may cause efficiency deterioration even thermal risks. The recognition of horizontal misalignment, including that in the longitudinal lateral direction, has been made gradual progress by previous works. While yaw angle, with rare attention, can also degrade performance, especially for those employing non-centrosymmetric...

Metal object detection (MOD) is indispensable for wireless electric vehicle charging (WEVC) systems safety concerns. Most recently, interests are growing in MOD by electromagnetic (EM) sensing. However, current works based on EM sensing rarely target the with DD coils, a promising coil type commercialization. Additionally, schemes mostly derived from mindset, viz., cooperation between two coils to obtain voltage difference as criterion. Hence, undesired out-of-phase incident becomes an...

Metal object detection (MOD) is crucial for the safe operation of ground-assembled wireless electric vehicle charging (WEVC) systems. Electromagnetic sensing by passive coils a reliable MOD method high-power applications, such as WEVC. Previous designs are mainly targeted at systems with unpolarized (e.g., circular coils). However, they not suitable those DD-coil-coupling engaged due to fundamentally different field pattern. To fix this problem, in article, field-oriented design proposed,...

A series theoretical models were established to explore the characteristics system, and experiments carried out verify characteristics.

Wireless charging systems (WCSs) are considered very appropriate to recharge underwater surface vehicles (USVs) due their safe, flexible, and cost-effective characteristics. The small depth of immersion USVs allows a WCS operated at an mm-level distance using dock. Resultant tight coupling between the transmitter receiver is conducive high power, yet faces challenge alleviating misalignment sensitivity. In addition, considering USVs’ endurance, weight should be strictly limited. this paper,...

Concerning thermal safety, the surface of ground assembly (GA) is deemed as most critical part wireless charging device for electric vehicles (EVs). As a result accumulated losses in process, its temperature gradually climbs, which may lead to dermal injury children and ignition combustible debris. In practice, it very usual that GA vehicle (VA) are not perfectly aligned, wherein rise will be even higher penalty efficiency deterioration. However, rarely attracts attention safety hazard. This...

Faced with the increasingly severe issue of greenhouse effect, wind power represents a sustainable solution.
