Dynamic wireless charging refers to the ability to charge a vehicle while it is in motion using resonant inductive power transfer. This is achieved by embedding source coils in the road and including a pickup coil inside the vehicle, these coils are coupled to get the maximum power transfer. From the point of view of the vehicle, dynamic wireless charging systems theoretically solve the Electric Vehicle (EV) battery problem by delivering unlimited range and making it possible to use smaller batteries, which reduce the cost and weight, however the implementation will be limited by the availability of the charging infrastructure, which in turn is limited by its cost. This paper presents a literature review on the recent advancements of stationary and dynamic wireless power transfer used for EV charging addressing power limitations, electromagnetic interference regulations, communication issues and interoperability, in order to point out the technology challenges to transition from stationary to dynamic wireless charging and the implementation challenges in terms of infrastructure.

Dynamic Wireless Power Transfer (WPT) is a developing technology which provides wireless extension of the power supply of an electric vehicle while it is in motion, allowing extending its range. Therefore, the communication between the roadside controller (RSC) and the onboard controller (OBC) needs to be wireless too. In order to support the deterministic behavior needed for WPT real-time control loops, the network needs to provide resource reservation for critical data streams via configuration, management, and/or protocol action, in addition to mobility. These characteristics cannot be addressed with the current networking solutions. Hence, a change in network design framework is required. This paper presents the characteristics of the communication system that need to be considered when designing WPT communication protocols and system architecture that supports realtime in-motion control applications and highlights the path to standardization of protocols for communication for real-time control loops.
