Korea Constructs Road That Wirelessly Charges Moving Electric Buses

People often think of switching to battery operated vehicles, but it becomes a nightmare for the drivers to look at the low battery sign on the dashboard with no means to recharge it again.

Maybe there is a way to release this fear. What if battery-operated electric cars work far better and don’t have to lug around huge and expensive batteries?

The researchers at Korea’s Advanced Institute of Science and Technology have developed a technology to solve both the conundrums. They have created first-of-its-kind on-line electric vehicle (OLEV) system, that can recharge electric cars or buses while they are on the go.

In the city of Gumi, South Korea, a seven-and-a-half-mile stretch of asphalt roadway has been constructed with power sources periodically embedded in the road. As a bus approaches and leaves, these power sources connect to the grid and are turned on and off selectively. According to KAIST, only 5% to 15% of the already existing road needs to be rebuild to make it a wireless charger.

The batteries used in the buses are almost third the size of a normal electric car battery, yet the buses don’t need to stop for charging and are more cost effective. This technology being eco-friendly can curb the increasing carbon level, hence solving many pollutions related health issues.

These roads will charge cars as they drive
by Ivana Kottasova and Alanna Petroff

Electric cars are cool. Running out of juice -- not so much.

The British government is getting ready to test out new road technology that would allow electric cars to charge as they drive. The goal is to help drivers with electric and hybrid cars avoid frequent stops to recharge their vehicles.

Most electric cars get charged via plug-in chargers at home or while parked on the streets. Wireless power charging "pods" are also available, but they too require the car to stop to get more juice.

The new charging roads proposed by the U.K. government will work kind of like wireless phone chargers, using magnetic induction technology.

The initiative is slated to begin later this year, and engineers will install wireless technology in test vehicles and place special equipment under the roads.

Cables buried underneath the highway would generate electromagnetic fields that could be picked up by a receiver in the car and transformed into electric power. The system would include a communication system, so that the roads can detect that a car is coming and start the process.

For now, the trials will be restricted to test areas where regular drivers aren't allowed. The government is committing £500 million ($779 million) to the project over the next five years.

"Vehicle technologies are advancing at an ever increasing pace and we're committed to supporting the growth of ultra-low emissions vehicles on England's motorways," said the government's chief highways engineer, Mike Wilson.

The government will also expand the number of charging stations available in the country, so there is a plug available every 20 miles.

Similar technology is already used in the South Korean city of Gumi, where shuttle buses covering distances of up to 15 miles get their juice from underground power cables.

This tech is effective for city roads. @Levina @thesolar65

Cool isn't it?
The biggest disadvantage of a battery operated car was the number of recharging hours (4-6hrs usually) and stopping for recharging.

he batteries used in the buses are almost third the size of a normal electric car battery

Should it mean the bus's battery is 1/3rd the size of a car? Is that possible?

I think India should also try its hand at constructing such roads, in not so populated cities like Chandigarh (may be?).

It means that the buses using wireless charging has much smaller batteries than even a standard electric car, as it is continuously charging itself while running on the road. @Levina

Batteries in electric vehicles are very costly, it will cut down that cost also..

How efficient is it?

South Korea has an abundance of energy production. We do not. Unless we build more power sources and fast - this will not become a viable option.

But this IS the future. Fossil fuels WILL end one day.

Gotcha!

Ah!

A kilo?

I do come here from time to time. Not as frequent though.

A kilo?

Yep. Kashmiris are called Kilos- a pet name given by our commandos.

Okay. :/

A problem of batteries is batteries dissipate electricity when they are not charged. After putting your mobile phone in your pocket for a few hours, nearly all the electricity is dissipated.

A problem with electromagnetic charging is the waves will cause cancer and sterility. All electromagnetic waves in the air cause cancer and sterility. Half of people already have trouble conceiving children.

Fossil fuels is the most healthy, the most natural, the most environmentally friendly.

These are great news, thanks for posting.

Oh, man, this statement suits your profile picture perfectly So, when can we get the oil price back to $40?
