I have seen a Qualcomm technology report on wireless charging of electric vehicles. I wonder if I can also try to design a wireless charging electric car. The main design idea is to embed the electric energy receiving equipment on both sides of the car body, and embed the electric energy transmitting equipment on the road guardrail whose mileage has been calculated, so that the electric vehicle can be dynamically charged at the least cost, so that the vehicle can be charged when driving. As a result, the defects of electric vehicles such as short cruising range, long charging time, and inconvenient installation of charging piles are effectively improved. This idea applies not only to electric passenger cars, but also to electric commercial vehicles such as electric buses and electric trucks.
