State of the Art in Inductive Charging for Electronic Appliances and its Future in Transportation

Inductive charging is a method of moving power wirelessly. A power generating source system is placed near a power storing or power transferring system. An electromagnetic field is generated between the two objects and power is moved from one system to the other. Inductive charging is a way of moving power from a main system to a subsystem such as moving the power from the power grid to a local transformer. It is applied to a wide variety of systems from small hand-held devices to robotic platforms and electric vehicles. In this study, the working principle, advantages, disadvantages and limitations of inductive charging mats/pads used for electronic devices are discussed. The new advancements in inductive charging for transportation are also reviewed in this study.
