As electrification is constantly on the rise, electric vehicle charging is a problem that is looking for a solution and a concern for those who own an electric vehicle or those who are thinking about purchasing one. Although there are few charging points in Greece today, as in Europe, efforts are being made every day to increase the number of points in order to ensure a smooth transition to electrification.

Now the cable has become a symbol of the automotive industry. But this symbol does not cease to be a reality, which is an annoying process for the driver. For many years, attempts have been made to get rid of the cable. The only way is inductive charging. That is, charging an electric car without using cables. This requires pre-processing both on the side of the energy source and on the side of the final receiver. The distance between the two devices should still be only a few centimeters so that there is no loss of electricity. Of course, efforts have been made lately to increase the distance without great losses.

Today’s accelerated power transfer rates are low and low power, comparable to those of small fast chargers. But things will change in the future and we will see inductive charging with more power.

There are two types of inductive charging. Statics and dynamics. The first refers to a transmitter of electrical energy placed at a fixed point, usually at road level, and a receiver on the underside of a vehicle. For charging to take place, the car must be parked directly above it and remain stationary for as long as it takes to charge. The second case is for a car that has a receiver on the underside of the car, but can receive electricity while driving over several transmitters in series on the pavement. Thus, the car can be charged while driving without necessarily stopping. This case is of great interest to companies working in this field, as they want to move to the next stage of electric vehicle charging. Lots of experiments and tests. Today, they can only achieve dynamic charging over a short distance. Those in charge of the work realized that there must be a section between the testing of asphalt materials and magnetic materials so that large surfaces can be built, providing electricity over long distances. Such a thing will have unconditional application in taxi companies, even on some sections of highways.

This form will give complete freedom to the driver of an electric car, who will see that he receives all the necessary energy without stopping. This will mainly help professional drivers, such as taxi drivers, who will get some of the electricity from the taxi ranks without having to stand in long queues. Of course, this method is supposed to be applicable in other cases, when the route of vehicles will be specific and predetermined, as well as on some sections of roads. But that’s much later…
