感应电能传输（IPT）具有安全、高效、方便等优点，是沿着行驶的电动汽车（EV）充电和供电的可行方法。然而，这是一个苛刻的应用，因为动力需要在150- 200 mm的相对大的气隙上传递，同时允许车道宽度上有足够的水平公差，以使非导向车辆能够接收全部动力。电源轨道的设计对于大规模实施至关重要，以确保损耗和成本最小化，同时最大限度地提高水平公差。本文中使用的方法克服了早期轨道设计的局限性，并允许设计人员以最小的成本增加水平公差，使EV道路系统在未来被考虑。一个2.5米长的轨道被建造用于实验室测试，并与3D有限元模型进行比较，之后，通过仿真优化设计，以满足电动汽车的公差和功率要求。
Inductive Power Transfer (IPT) is a viable method for recharging and powering Electric Vehicles (EV) along a roadway since it is safe, efficient and convenient. This is however, a demanding application because power needs to be transferred over relatively large air gaps of 150–200mm while allowing sufficient horizontal tolerance across the width of the lane, to enable an unguided vehicle to receive full power. The design of the power track is critical to large scale implementation, to ensure that losses and cost are minimised while maximising horizontal tolerance. The approach used in this paper overcomes the limitations of earlier track designs and allows designers to increase horizontal tolerance with minimal cost, enabling an EV roadway system to be considered in future. A 2.5m long track is built for lab testing and compared to a 3D finite element model, after which, the design is refined via simulation to meet the tolerance and power requirements of an EV.
