Road-powered electric vehicles (RPEV)

1) Sustainability problem: Battery cost, weight, and range have hindered widespread adoption of the EV Area: Energy

  • EV batteries pose the biggest hurdle in widespread adoption of EVs
  • They are bulky and expensive and have limited range
  • EVs need to be charged for far longer periods compared to gasoline-powered cars
  • The supply chain is risky as some of the critical elements required for the battery such as Cobalt and Rare earth elements come from either war-torn countries (DRC) or from monopolies (China)

2)  Technology

  • The network consists of 24 kilometers of road in the city of Gumi, South Korea, and for now, only the Online Electric Vehicle (OLEV) developed by South Korea’s Advanced Institute of Science and Technology (KAIST) can run on them.
  • Power delivered by cables that are 12 inches below the surface of the road, the power is transmitted via Shaped Magnetic Field in Resonance (SMFIR) also developed by the institute.
  • The underside of the OLEV bus is equipped with a pick-up coil that’s tuned to pick up that frequency, and thus AC electricity is produced via magnetic resonance.

3) Stakeholders

  • EV manufacturers
  • EV customers
  • Governments
  • Public Transit users

4) Deployment 

  • The technology will first have to be shown as viable in a commercial scale project.
  • Infrastructure policy needs to be developed in order for roads to be retrofitted with this technology
  • Bus and car manufacturers need to be mandated to use this technology.
