“…Considering the control scheme without wireless communication for the power converter on the vehicle side had been well analyzed in [32], and this paper focuses on grid integration of DWPT where the power conversion circuit and battery module are considered as an equivalent resistor to simplify the model. To alleviate the power fluctuation from the varying mutual inductance between the transmitter and receiver coils, a double synchronous exciting method [33]- [35] is adopted in which two adjacent transmitter coils near the receiver coil are energized, and the other transmitter coils are open-circuited.…”

“…Each EV in the traffic flow is charged from one specific charging pad. e.g, if 20 pads are required to be turned on, the system will automatically calculate the serial number of them: 1,6,11,16,21,26,31,36,41,46,51,56,61,66,71,76,81,86,91,96, as shown in FIGURE 5. Then the sensors at both ends of charging pads and the EV will be activated.…”

Dynamic wireless charging for Electric Vehicles (EVs) can promote the take-up of EVs due to its potential of extending the driving range and reducing the size and cost of batteries of EVs. However, its dynamic charging demand and rigorous operation requirements may stress the power grid and increase carbon emissions. A novel adaptive dynamic wireless charging system is proposed that enables mobile EVs to be powered by renewable wind energy by taking advantages of our proposed traffic flow-based charging demand prediction programme. The aim is to cut down the system cost and carbon emissions at the same time, whilst realising fast demand prediction and supply response as well as relieving the peak demand on the power grid. Simulation results show that the proposed system can adaptively adjust the demand side energy response according to customers' welfare analysis and charging price, thereby to determine the power supply method. Moreover, due to the prioritised use of renewable energy, EV charging system requires less electricity from the power grid and thus the overall carbon emissions are reduced by 63.7%.

“…More importantly, WPT facilities including power supply system and WPT transmitting system are required to be economically [15,16] constructed along the lane, forming a DEVWC roadway. In practice, the DEVWC roadway is often split into a number of individual segments [3,10,13,14,[17][18][19][20][21][22][23]. Power converters and bus switches are connected to each segment so that its function state and current can be freely controlled.…”

In practical dynamic electric vehicle (EV) wireless charging applications, the charging roadway is segmented and the segments are switched on and off along with the passing-by EVs, which often causes output power pulsations. Here, the decoupling characteristics of two general inductively coupled coils are investigated. Based on which, an easy-implement switching strategy to minimise the output power pulsation in the repeatedly occurring segmental switches is proposed. Each segment is to be switched on when a coming EV passes the entry-end decoupling point of that segment, and to be cutoff when the vehicle passes the other decoupling point as it leaves from the other end. Practical issues regarding to the coil dimensions have also been studied to investigate the compatibility of the proposed method. Dynamic charging and segmental switching experiments on a predesigned 2.5 kW dynamic wireless charging prototype were conducted to testify the proposed method. Smooth transition with zero output power pulsation and noticeable improvement on the systematic efficiency over the transition zone were achieved.
