Dynamic Wireless Charging: A Game-Changer for Electric Vehicles

By Muhammad Zakir Satti | April 18, 2024

Introduction

Dynamic wireless charging is a revolutionary technology that has the potential to change the way we power our electric vehicles (EVs). With dynamic wireless charging, EVs can charge as they drive on specially equipped roads, eliminating the need for traditional charging stations and reducing range concerns. This technology has the potential to significantly reduce greenhouse gas emissions, improve air quality and reduce our dependence on fossil fuels.

How Does Dynamic Wireless Charging Work?

Dynamic wireless charging uses magnetic inductive power transfer to transfer energy from the roadway to the vehicle. The roadway is equipped with a series of power charging couplers that are connected to the power supply. The vehicle is equipped with a receiver that picks up energy from the couplers. The energy is then transferred to the vehicle’s battery, which is charged as the vehicle moves.

Dynamic wireless charging can work on a variety of road types, including asphalt and concrete. It can be used for both slow and fast charging. The ENRX Electric Roadway’s unique patterned technology has demonstrated an overall efficiency of over 90 percent and a proven continuous charging capacity of 180 kW.

Benefits of Dynamic Wireless Charging

Dynamic wireless charging has several advantages over conventional charging methods. First, it eliminates the need for traditional charging stations, which can be expensive to install and maintain. Second, it reduces range anxiety, as EVs can charge while driving, ensuring they always have enough power to reach their destination. Third, it can reduce the required capacity of the onboard battery, which can reduce the weight and cost of EVs.

Dynamic wireless charging can also contribute to reducing greenhouse gas emissions and electrifying road transport. Integration of this technology into smart grids can help manage electricity demand and optimize the use of renewable energy sources.

Challenges of Dynamic Wireless Charging

Although dynamic wireless charging has many advantages, there are also challenges in the design and implementation of dynamic wireless charging systems. First, the design of the power charging coupler and compensation network can be complex. Second, foreign object detection systems are essential to ensure that objects on the road do not interfere with the charging process. Third, economic factors, such as installation and maintenance costs, need to be considered. Fourth, microgrid-integrated DWPT systems need to be designed to optimize the use of renewable energy sources.

Implementation of Dynamic Wireless Charging

Dynamic wireless charging has already been implemented in some places around the world. In Israel, ElectReon, a world leader in dynamic wireless power transfer technology, has successfully tested the wireless charging of a long-distance electric truck driving on a public road in Tel Aviv. The company installed 700 meters of dynamic charging segments on a road in Ramat Aviv, and a wireless charging system was used to charge the truck as it drove at varying speeds of 60 km/h, with an average transfer rate of 70 kW. . Road to receivers and truck battery. The system reached stable operation with consistent results, and testing confirmed that ice and snow did not affect wireless charging capabilities.

In the United States, Kansas City International Airport (KCI) has implemented a first-of-its-kind EV wireless charging system that uses inductive charging to extend the range of electric buses without an above-ground charging station. Is. Plug-in infrastructure.

Conclusion

Dynamic wireless charging is a promising technology that has the potential to significantly reduce greenhouse gas emissions, improve air quality and reduce our dependence on fossil fuels. Although there are challenges involved in the design and implementation of a dynamic wireless charging system, the advantages of this technology make it a worthwhile investment. With continued research and development, dynamic wireless charging has the potential to change the way we power EVs and contribute to a more sustainable future.
