      <title>Review and Study of Dynamic Wireless Power Transfer Technology for In-road Charging of Electric Vehicles</title>
      <link>https://rip.trb.org/View/2507249</link>
      <description><![CDATA[Electric vehicles offer tremendous opportunity to reduce emissions and save fuel and maintenance costs. However, significant challenges, centered around range and supporting charging infrastructure, remain in the pursuit of widespread adoption of electric vehicles. The emerging inductive Dynamic Wireless Power Transfer (DWPT) technology offers a promising solution to address these challenges. By charging electric vehicles in road using inductive DWPT devices, power can be brought to the vehicles where they drive. This will lead to smaller and longer-lasting batteries on vehicles, making electric vehicles less expensive to purchase and operate than their fossil fuel counterparts. In-road charging using inductive DWPT will also enable unlimited electric vehicle range and a seamless charging experience for drivers of electric vehicles. These improvements will help accelerate widespread adoption of electric vehicles.
In the past few years, multiple in-road charging pilot projects have been completed or launched in the United States. For example, the nation’s first inductive wireless charging road was opened in Detroit, Michigan in November 2023, which spans a quarter mile on 14th Street, between Marantette and Dalzelle streets. The road is equipped with inductive DWPT devices that can charge electric vehicles as they drive on the road. Another pilot project was launched on U.S. Highway 52 in Indiana this year, which aims at testing wireless charging for electric vehicles, particularly heavy-duty electric trucks, traveling at highway speeds. These early projects provide useful information for the planning, design, and implementation of the pilot in-road charging system to be installed in the I-80 6-line, Seward to Pleasant Dale project. However, the adoption of in-road charging infrastructure using the inductive DWPT technology is still in very early stages. Many questions and issues remain in the pursuit of widespread adoption of the DWPT technology for in-road charging of electric vehicles.]]></description>

      <title>Inductive Vehicle Charging</title>
      <link>https://rip.trb.org/View/2406647</link>
      <description><![CDATA[The Biden Administration has made the transition from fossil fuel-powered vehicles to electric vehicles (EVs) a priority in the
United States, and as a state transportation agency with one of the nation’s mobility hubs, the Michigan Department of
Transportation (MDOT) is tasked with making EVs more accessible to the public. One major challenge for EVs’ broad acceptance
is “range anxiety,” which describes an EV user’s worry that the car battery will run out before they can reach a charging point.
MDOT is aiming to be the first in the nation to ease range anxiety with a new innovative solution: inductive vehicle charging. This
technology allows EVs to wirelessly charge in motion while driving over a road with embedded charging coils. The proposed
research will evaluate, analyze, and validate the effectiveness of this technology and identify ideal locations for implementation.
Researching this system in Michigan allows this technology to be tested in a variety of weather conditions and potentially prove
its usefulness to the public. If proven effective this technology could be expanded across the country for the benefit of the public.]]></description>

      <title>Transportation Infrastructure Electrification Certificate Program</title>
      <link>https://rip.trb.org/View/2381671</link>
      <description><![CDATA[The future of electrified transportation infrastructure operates at the nexus of several critical industries (such as Transportation, Building, Power/Energy, Information Technology, Data Science, and Economics) that have historically operated independently, and the ever-increasing overlap among them has little to no strategic coordination. A coherent understanding of these complex interactions is required to capture and harness convergence across these industries and scientific communities and to reshape forever the future. The Transportation Infrastructure Electrification Certificate Program will be a collaborative effort pulling domain experts from the aforementioned disciplines and to train graduate students by applying knowledge from across numerous domains to tackle one of the most significant social issues of our time, preparing them to adapt to an increasingly interdisciplinary world, as well as increasing awareness of the many system-level impacts issues permeating life in the U.S. and elsewhere.

The program’s vision is to create entirely new lines of thinking on how city, highway, electric grid infrastructures are designed, how vehicles and operators interact with those systems, and how to integrate private sector partners and public resources in the human interface of planning, economics, and policy.]]></description>

      <title>SPR-4856:  Receiver, Vehicle, and Roadway Systems for a Dynamic Wireless Power Transfer Roadway Testbed</title>
      <link>https://rip.trb.org/View/2253923</link>
      <description><![CDATA[This project will support the installation of a one-quarter mile long dynamic wireless power transfer (DWPT) testbed on northbound US-231 in West Lafayette. At the end of this project, INDOT will have a fully functional pilot DWPT constructed and key testing of the performance of the system will be performed.]]></description>

      <title>Wireless Power Transfer Research Topic</title>
      <link>https://rip.trb.org/View/2175604</link>
      <description><![CDATA[In the context of the growing electrification of transport vehicles, wireless power transfer (WPT) appears as an appealing alternative technology as it enables road powered electric vehicles (RPEVs) to charge while driving and without any mechanical contact (i.e., overhead cables or rails in the ground). Although the technology dates from the end of the 20th century, recent advances in semiconductor technologies have enabled the first real demonstrations. It is within this context that the Florida Department of Transportation has requested a white paper and preliminary literature review and state of the practice assessment on this technology]]></description>

      <title>In-Road Electric Vehicle Charging for Parked Vehicles</title>
      <link>https://rip.trb.org/View/2122522</link>
      <description><![CDATA[The global electric vehicle (EV) market is forecasted to grow by 24.3% till 2028 constantly. However, the development in charging infrastructure is still lagging behind that, hindering the EV's widespread application, i.e., 30 million chargers are still needed to support the existing EV demand. The project's objectives are (1) design a wireless charging station that allows charging multiple autonomous electric vehicles (AEVs) in the parking lot to increase efficiency, eliminate the need for individual charging wires for each EV, turn the passive parking time into a productive time, and increase the autonomy of charging process, (2) design the communication system between charging stations and AEVs (charger reservation system), the interaction between charger and AEVs, and safety. The main goal of this project is to design an inductive charging station for a fleet of automated shuttles.   ]]></description>

      <title>SPR-4607: Full-scale Dynamic Wireless Power Transfer and Pilot Project Implementation</title>
      <link>https://rip.trb.org/View/1862992</link>
      <description><![CDATA[The objectives of this project are: (i) develop a better understanding of pavement/ dynamic wireless power transfer (DWPT) system interaction, including DWPT reaction to environment and traffic loads and pavement materials responses to operational DWPT; and (ii) support the design and installation of a 215 kW DWPT system pilot for heavy-duty vehicles on an existing INDOT roadway. The pilot project will help develop construction techniques and provide a real-world testbed for optimizing the pavement/DWPT system.
