Piezoelectric Roads System with Wireless Electric Vehicle Charging

The sustainable energy-based electric vehicle (EV) charging system presented in this study combines static wireless power transmission with piezoelectric road energy collection. In order to capture mechanical energy produced by vehicle movement, the suggested system makes use of piezoelectric sensors buried beneath road surfaces. The piezoelectric effect transforms this mechanical stress into electrical energy. A localized energy storage system is created by rectifying, regulating, and storing the produced electrical energy in a rechargeable battery. The stored energy is then utilized to run a wireless charging station that uses inductive coupling between transmitter and receiver coils to charge electric cars in a static state. This increases durability, safety, and convenience by doing away with the necessity for direct physical connections. The need for effective and environmentally friendly charging infrastructure is rising quickly due to the growing popularity of EVs. While this technology uses renewable energy from otherwise wasted mechanical vibrations of traffic, conventional charging systems rely largely on grid electricity. Despite the relatively low power output of piezoelectric sensors, the system may be used for auxiliary support and low-power charging applications, helping to build intelligent, sustainable, and energy-efficient transportation infrastructure.
