“…A few years later, the Wireless power transfer transmission for EVs evolved, which can overcome the disadvantages of wired chargers and remove specific barriers to vehicle electrification and long-term mobility [13]. Aside from being more convenient than wired chargers, WPT allows for substantial reductions in the size of the onboard EV battery [14]. Also, electric buses were considering the stationary WPT charging method.…”

WPT system performances highly depend on the misalignment scenarios of the transmitter or the receiver coil. In this contribution, the authors analyze the effect of the misalignment influencing factors of the integrated WPT-PLC system receiving coil on the system performances. The simulations and experimental analysis are based on power efficiency and channel capacity metrics. The simulations are performed using finite element calculations in COMSOL Multiphysics and Advanced Design System (ADS) from Keysight technology. By analyzing the results, maximum transferred power is reached under resonance conditions. For instance, the calculated efficiencies versus the misalignment cases of the WPT-PLC system varies (η = 86% to 60%) when d = [3 cm to 7 cm], s = [3 cm to 9 cm], and for a tilt angle θ ≤ 20 deg, while the optimal data rate C(bps) is achieved while appealing different data access points and under reasonable SNR value.

This paper analyses the conceptual application of a wireless power transfer (WPT) system with multiple resonators supplying outdoor sensors using a mobile charger. The solution is based on the idea of using sensors, located in open space, to monitor environmental parameters. Instead of the typical two-coil WPT with a single charger, energy transfer is realized simultaneously, using a group of identical planar coils as transmitters and receivers connected to the independent power supply circuits of each sensor and microcontroller. By isolating these charged circuits, a higher reliability and powering flexibility of the weather station can be achieved. The concept of the proposed system was discussed, and it was proposed to include the main devices in it. A theoretical analysis was performed considering all mutual couplings and the skin effect; hence, the system is characterized by a matrix equation and sufficient formulae are given. The calculations were verified experimentally for different frequencies, two possible distances between the transmitters and receivers, and equivalent loads. Both the efficiency and load power are compared and discussed, showing that this solution can provide power to ultra-low-power devices, yet the efficiency must still be improved. At the small distance between the transmitting and receiving coils (5 mm), the maximum efficiency value was about 40%, with a load resistance of 10 Ω. By doubling the distance between the coils, the efficiency of the WPT system decreased by three times.
