On-Line Electric Vehicle (OLEV)
The OLEV system doesn’t need charging stations because the vehicle is charged wirelessly in real time while running on the road. Since its battery capacity also is reduced to 20% of that of a typical pure electric vehicle, the OLEV is regarded as an enabling technology to speed up the commercialization of electric vehicles.
The OLEV technology was successfully applied and demonstrated in Seoul Grand Park by installing about 400m of power cables on 2.2km circular track and operating an OLEV tram. Furthermore, KAIST Wireless Power Transfer Research Center has decided to launch the electrification projects in Park City, Utah, United States and Kuala Lumpur Airport, Malaysia.
Is this a possible answer to charging station problems with electric cars... don't have any?
Sure, it's going to require a massive investment in infrastructure but it at least addresses the issue of transportabilty of energy.
Clarkson pointed out that the Mercedes-Benz SLS AMG Electric, couldn't go very far on a charge but if it was constantly being charged whilst being driven - problem sorted.
