The electric roads that charge your car as you drive

Electric roads, also known as electrified or smart roads, are a concept in transportation infrastructure designed to charge electric vehicles (EVs) as they drive on the road. The idea behind electric roads is to provide a continuous source of power to EVs, eliminating the need for frequent charging stops and extending their range. There are several ways this concept can be implemented:

Inductive Charging: One common method for electric roads is inductive charging. This involves embedding coils in the road's surface, which generate electromagnetic fields. When an EV equipped with a compatible receiver drives over these coils, it induces an electric current, which is then used to charge the vehicle's batteries. This technology is similar to wireless charging used for some smartphones and electric toothbrushes.

Overhead Charging: Another approach is to install overhead power lines or conductive rails above the road. EVs equipped with the necessary technology can make contact with these overhead lines, drawing power from them as they drive. This method is sometimes referred to as "catenary charging" and is similar to how some trams and trolleybuses are powered.

Dynamic Wireless Charging: Dynamic wireless charging systems involve transmitting power to EVs while they are in motion. These systems typically use magnetic resonance or other wireless power transfer technologies to transmit electricity to a receiver on the vehicle as it moves along the road. Dynamic wireless charging is still in the experimental stage but holds promise for future applications.

Benefits of Electric Roads:

Extended Range: Electric roads can significantly extend the range of electric vehicles by providing continuous charging w
