Abstract
In the next decades, the number of electric vehicles (EVs) for private use is predicted to increase considerably. Charging the EVs through wireless power transfer (WPT), i.e. wireless charging, has the potential to shorten charging duration of EVs batteries through dynamic charging and it would also improve the safety of static charging in case of wet weather conditions. From 2015, standards and regulations have been released such that common constraints can be defined. Therefore, it is essential to be aware of these regulations before designing an EV wireless charging system, such that it can become an actual application. This paper focuses on the available regulations and standards on EVs charging through WPT. These regulations are explained individually and then, they are compared and discussed mainly in terms of the electromagnetic compatibility (EMC) and exposure of humans to the radiated magnetic field limits. To gain a better understanding, a quantitative and qualitative interpretation of these limits is also given.
