Abstract

For the dynamic wireless charging (DWC) system of electric vehicle (EV) with short transmitter coil structure, the connection and driving modes of transmitting coil are various, which increases the complexity of system design. In addition, the uncertainty of the number of EV also puts higher requirements on charging control strategies. This paper proposes an integrated circuit design method based on ground-side switching control and resonance compensation. Furthermore, the design and control method of the ground-side circuit of the DWC system for multiple EVs with parallel transmitter coils are developed, which can greatly reduce the cost and volume of the system hardware. Then, the power control and efficiency optimization strategies based on the vehicle-side controllable rectifier circuit are proposed by analyzing the output characteristics of the DWC system for multiple EVs with parallel transmitter coils. Finally, the effectiveness of the proposed method is verified by simulation. The experimental results of 330W show that when adopting the ground-side integrated circuit control strategy and power control method proposed in this paper, the output power fluctuation of the system is only 1.23% when multiple loads are connected. The proposed efficiency optimization strategy can increase the output efficiency of three electric vehicles during charging from 86.97% to 88.81%.

短段发射线圈多辆电动汽车动态无线充电系统的充电控制策略

对于具有短发射线圈结构的电动汽车动态无线充电系统，发射线圈的连接方式和驱动方式多种多样，增加了系统设计的复杂性。此外，电动汽车数量的不确定性也对充电控制策略提出了更高的要求。提出了一种基于地侧开关控制和谐振补偿的集成电路设计方法。在此基础上，提出了多车并联发射线圈DWC系统地侧电路的设计和控制方法，大大降低了系统硬件的成本和体积。在此基础上，通过分析并联发射线圈的多辆电动汽车DWC系统的输出特性，提出了基于车侧可控整流电路的功率控制和效率优化策略。最后，通过仿真验证了所提方法的有效性。330W的实验结果表明，采用本文提出的地侧集成电路控制策略和功率控制方法时，多负载并网时系统输出功率波动仅为1.23%。所提出的效率优化策略可使三辆电动汽车在充电时的输出效率从86.97%提高到88.81%。
