“…Interference with other materials of the e-bike has not been considered, as the prototype does not include this type of vehicle. A seriesresonant inductive system is proposed in [13] for a wireless charger. It also suffers from the same inconvenience as the previous approach because it includes an E-shape coil with ferromagnetic material.…”

“…Wireless chargers count on matching networks to make the system operate at resonance. The most simple topology is the Series-Series, as used in [13], but there are other multiresonant approaches. The work in [16] proposes the use of switched capacitors and coils on the secondary side to have a different circuit when the battery is charged in CC or CV mode.…”

Wireless charging is a convenient method of charging Electric Vehicles (EVs). Its application has been widely studied for electric cars but so far there have been limited experiments for electric bicycles (e-bikes). This paper addresses the design process and implementation details related to a wireless charger for a specific e-bike. Some issues such as the position of the secondary coil or the control algorithm prove to be crucial to the performance of the wireless transfer. Concerning the placement of the secondary coil, the paper proposes and validates a theoretical model to quantify the effects of the surrounding interfering materials. A CC-CV (Constant Current -Constant Voltage) control algorithm has been implemented to validate the theoretical results in these two charging phases. The control, the coils and the compensation networks have been designed to be simple and robust. The theoretical model, the charger and its control have proven to be effective in a real 84-W e-bike.INDEX TERMS Control, Coil position, Electric bicycle, Wireless charger.

“…This auxiliary power has to be injected into the direct current (DC) power supply system in order to obtain an annual output power payback, energy conservation, and emissions reduction [14,15]. Moreover, Becherif et al [16] presented the concept of an embarked power source using SCs that were charged by means of a combination of a roof-placed PV source and an aero generator, which supplied power to the DC link of the main traction drive.…”

Abstract:The growing interest in the use of energy storage systems to improve the performance of tramways has prompted the development of control techniques and optimal storage devices, displacement, and sizing to obtain the maximum profit and reduce the total installation cost. Recently, the rapid diffusion of renewable energy generation from photovoltaic panels has also created a large interest in coupling renewable energy and storage units. This study analyzed the integration of a photovoltaic power plant, supercapacitor energy storage system, and railway power system. Random optimization was used to verify the feasibility of this integration in a real tramway electric system operating in the city of Naples, and the benefits and total cost of this integration were evaluated.

Summary PV‐based and wired type of the electrical bicycles (e‐bike) battery charging stations widely is spreading because of the resonant network limitations and low efficiency of the wireless mode for these stations. The generated voltage of many of the PV panels such as JIYANGYIN HR‐200 W‐24 V at the maximum power point is around 36VDC. So, a step‐down converter with a PID controller for Maximum Power Point Tracking (MPPT) of the PV panels is considered between PV panels and boost converter in order to decrease this voltage and enhance the current values for the load side. A sliding mode controller (SMC) equipped with a non‐isolated DC‐DC boost converter with reduced voltage stresses on the power switch is presented. The step‐up converter increases the voltage to the utility level of the e‐bike with around 360 Wh amount of energy. The main concerns about the converters are the efficiency, voltage, and current stresses, number of active or passive components in the converter topology and simplicity. In comparison with a conventional step‐up converter, the selected converter has a lower dynamic loss in the input inductor that can give a proper efficiency by considering its higher voltage gain. The average state‐space model for the SMC is used and the main advantage of the controller is its independency to the inductor current or the amount of the load. The proposed SMC is compared with PID and Fuzzy Logic Controller (FLC) methods and based on the results, the robustness, overshoot, and damping factor of the controller are at an acceptable and better level. All mathematical, simulation and comparison results are presented. A 720 Wh circuit has been implemented for charging all types of the Li‐Ion or Li‐Polymer batteries with 36VDC and 10 Ah specifications.
