EV News (AUG.6,2013): World's First Road Embedded Wireless Electric Bus Network Opens

Two cordless rechargeable Hyundai battery electric buses have been put in service this week in a pilot program in Gumi, South Korea.

The Online Electric Vehicle (OLEV), developed by the Korea Advanced Institute of Science and Technology (KAIST), is an electric vehicle that can be charged while stationary or driving, thus removing the need to stop at a charging station. Likewise, an OLEV tram does not require pantographs to feed power from electric wires strung above the tram route.

Two OLEV buses will run an inner city route between Gumi Train Station and In-dong district, for a total of 24 km roundtrip. The bus will receive 20 kHz and 100 kW (136 horsepower) electricity at an 85% maximum power transmission efficiency rate while maintaining a 17cm air gap between the underbody of the vehicle and the road surface.

OLEV is a groundbreaking technology that accelerates the development of purely electric vehicles as a viable option for future transportation systems, be they personal vehicles or public transit. This is accomplished by solving technological issues that limit the commercialization of electric vehicles such as price, weight, volume, driving distance, and lack of charging infrastructure.

OLEV receives power wirelessly through the application of the "Shaped Magnetic Field in Resonance (SMFIR)" technology. SMFIR is a new technology introduced by KAIST that enables electric vehicles to transfer electricity wirelessly from the road surface while moving.

Power comes from the electrical cables buried under the surface of the road, creating magnetic fields. There is a receiving device installed on the underbody of the OLEV that converts these fields into electricity. The length of power strips installed under the road is generally 5%-15% of the entire road, requiring only a few sections of the road to be rebuilt with the embedded cables.

OLEV has a small battery (one-third of the size of the battery equipped with a regular electric car). The vehicle complies with the international electromagnetic fields (EMF) standards of 62.5 mG, within the margin of safety level necessary for human health.

The road has a smart function as well, to distinguish OLEV buses from regular cars—the segment technology is employed to control the power supply by switching on the power strip when OLEV buses pass along, but switching it off for other vehicles, thereby preventing EMF exposure and standby power consumption. As of today, the SMFIR technology supplies 60 kHz and 180 kW of power remotely to transport vehicles at a stable, constant rate.

After the successful operation of the two OLEV buses by the end of this year, Gumi City plans to provide ten more such buses by 2015.

EV News (AUG.1,2013): Renault makes a silent arrival at the château de Versailles

In the XVIIth century, carriages were the only vehicles on the avenues of the Château de Versailles… In 2013, as we celebrate the 400th anniversary of the birth of André Le Nôtre, the gardens he designed have become havens of calm once again thanks to Renault’s electric vehicles. A partnership combining an environmental focus with the comfort and safety of visitors.

To mark the 400th anniversary of the birth of André Le Nôtre, the King’s gardener, the château de Versailles wished to restate its concern for the environment and its commitment to sustainable development. One solution came naturally to mind when looking for a mobility solution that could be used for the monitoring of the 43 km of gardens, the upkeep of the 350,000 trees in the grounds, and the planting of 300,000 flowers: only all-electric vehicles could ensure the absence of nuisance in the gardens while respecting visitors.

Renault is the only manufacturer to market a range of all-electric vehicles, from a quadricycle to an LCV, a saloon and city car. For this reason, Renault and the château de Versailles have decided to develop a partnership that will protect the environment of the gardens and safeguard the comfort and safety of 12 million annual visitors.

Twenty-three zero-emission (Z.E.) vehicles will meet the many and varied needs of the domain of Versailles. Three ZOE vehicles are used by service staff to get around the grounds or travel between the national domain of Versailles and Marly; ten Kangoo Z.E. vans, maxi glazed or extended cab versions, are used by the gardeners and curators to carry rare objects, statues, plants and tooling, while ten Twizy quadricycles are used by security staff who appreciate their agile performance in accessing narrow alleyways or when immediate action is required.

Around thirty charging stations have been installed around the national domain of Versailles, as part of a careful layout that respects the architectural integrity of the chateau and grounds, i.e. under the lower windows of the Grande Ecurie stables, in the Trianon domain, at Marly and in the Orangery gardens.

As a nod to history: curious visitors will be able to see a Twizy that is a little bit special: the “Twizy carriage” featuring the decoration found on the carriage owned by the Dauphin or heir to the throne, the future Louis XVII.

EV News (AUG.1,2013): Panasonic to make more lithium-ion batteries to meet robust US automotive demand

Panasonic will increase domestic production of lithium-ion battery used for automobiles to meet robust demand in the United States, company officials said on Thursday.

The electronics maker will resume operation of idled lines at the Suminoe Plant in Osaka Prefecture, which produces batteries for U.S. automaker Tesla Motors Inc., as early as next January, while another factory in Kaizuka City in the prefecture, which the company has suspended its operation since March, will reopen by the end of next fiscal year, Panasonic spokesperson Megumi Kitagawa said.

She also said that the company will add some manufacturing lines at the Kasai plant in Hyogo Prefecture, which produces batteries for domestic automakers, by the end of the current fiscal year through next March.

In June Panasonic announced that shipments of its automotive-grade lithium-ion battery cells for Tesla Motors’ premium, all-electric Model S sedan surpassed 100 million units.
