Electrische wagens draadloos opladen de uiteindelijke oplossing?

[Micele]

Ik denk nu aan steden "met veel appartemenen" waar het wegdek en hun parkeerplaatsen sowieso regelmatig vernieuwd of opengebroken moeten worden (ook voor versleten of lekkende nutsledingen, meestal elec)

Of van traagladende slimme laadpalen in de buurt van appartementen en/of naar draadloos traagladend opladen via het lokaal wegdek of onder parkeerplaatsen. Dat kan ook langs de rijbaan zijn, vul maar in.
Beide gaat natuurlijk ook, kwestie van laadprijs en comfort (geen kabel meer te gebruiken maar voor dat comfort graag wat meer wil betalen...)

In de toekomst van nog meer overtollige groene stroom (van wind en zon) hoeft die stroom niet op het net geduwd te worden of opgeslagen te worden voor later.

In elk geval zijn er steeds meer pilootprojecten voor de efficiëntie te verbeteren. Zweden onder andere past het toe voor taxi's (bekijk het filmpje op volgende link). In Detroit hebben ze nu (alweer) een wegsegment van 400 meter afgewerkt (link eronder).

Electreon bvb, opgericht in 2013, heeft ondertussen 18 diverse draadloze wegprojecten uitgevoerd.

Electreon was initially founded in 2013, and the company currently has 18 different wireless EV charging roads across Europe and elsewhere. The projects wireless charging projects are actively happening in Sweden, Norway, Italy, Israel and a handful of other countries on the continent.

Wireless EV charging roads piloted in the U.S., Europe

By Zachary Visconti Posted on September 11, 2023

As the world transitions from gas cars to electric vehicles (EVs), many remain concerned about the lack of charging infrastructure that’s currently available. More charging stations are being built, though many companies are also studying electrified roads — which could allow EVs to charge wirelessly as they drive.

Israel-based company Electreon is one such company piloting wireless roads, as detailed in a report from CNBC on Monday. The company currently has pilots running in Sweden, Norway, Italy, and other European countries, and it has plans for an electrified highway in the U.S.

“This is really an approach that can charge vehicles in any type of shape, meaning vehicles that are both buses or vans or passenger cars or trucks — but it can also charge a vehicle while either driving or while standing still,” said Stefan Tongur, Electron’s VP of U.S. business development at Electreon, in an interview with CNBC.

One Electreon project in Sweden is set to connect the town of Visby on Gotland Island to a regional airport via a wirelessly charging electric roadway. The Swedish government helped finance the vast majority of the $10.5-million project, which Electreon calls a “pre-commercial demonstration project” of the electrified road concept.

In the U.S., the first electric road will land near Detroit, where the Michigan Department of Transportation (MDOT) has partnered with Electreon.

Announced last year by Michigan Governor Gretchen Witmer, the program was initially expected to establish a wirelessly charging road for EVs by this summer. CNBC says the road is now expected to be built within the next year or so in a partnership between Electreon, NextEnergy, Jacobs Engineering Group, and MDOT.

“We really are looking hard within this pilot project to look at the different use cases that are out there,” said Michele Mueller, senior project manager of connected and automated vehicles at the MDOT. “There are use cases for freight, transit, but then also passenger vehicles.”

The electric road solution is considered especially useful for fleet vehicles, public transit, and other automobiles driving on repetitive routes. For example, a wireless charger at a bus stop could help the bus stay charged throughout an entire service day. One company previously also shared a solution for wirelessly charging the Tesla Semi.

Another critical use case for wirelessly charging roads is in rural communities with few charging stations, as Purdue University professor of civil and biological engineering Nadia Gkritza points out.

“We don’t view 100 percent of roads being electrified, but we definitely see this technology being viable,” Gkritza says. “…financially and also essential in rural areas where we might not have a lot of charging stations, or we have what we call charging deserts.”

Last week, a new study was released analyzing EV charging infrastructure in each U.S. state and Europe. Researchers ranked the involved countries and U.S. states based on several factors related to the density of EV chargers in those areas.

First wireless charging road in the U.S. completed in Michigan

By Zachary Visconti Posted on December 4, 2023

Talk of wireless charging roads for electric vehicles (EVs) has been underway for the past several years, but the first U.S. project to feature the technology has now been completed. The wireless charging road is set to continue construction through the end of the year, with testing set to follow early next year.

After the state of Michigan pledged in 2021 to complete a wireless charging road by this year, Israeli startup Electreon has finished installing the EV charging road, according to a press release shared by the company last week. While it isn’t yet open to the public, the city plans to open the road to the public in the next few years after a testing period.

Electreon says it plans to begin extensive testing of the inductive charging road in early 2024, using a Ford E-Transit equipped with its proprietary receiver.

“For more than a century, Detroit has been known around the world as the leader in transportation innovation,” Detroit Mayor Mike Duggan said in the release. “We are the birthplace of the auto industry, and the home of the first mile of concrete road and the first three-way traffic signal. Today, thanks to Gov. Whitmer and our partners at Michigan Central and Electreon, we can add the nation’s first wireless charging public roadway to that list of innovations.”

The road is located in the former Book Depository Building in the Michigan Central district, on a quarter-mile stretch of Detroit’s 14th Street. The tests will focus on the road’s charging efficiency and will be used to evaluate the EV charging road’s potential for long-term public transportation use.

“If this was easy, it would have already been done,” said Todd Bettison, Detroit deputy mayor, at a recent event (via Automotive News). “We’re in competition across the world … in electrification. This will be our own proving ground in the city of Detroit.”

The concept of wireless EV charging is expected to be particularly useful for vehicles using repetitive routes, such as buses, taxis, and freight vehicles, though they’re also expected to be available to passenger vehicles in the future.

The wireless EV charging technology works through electromagnetic induction using embedded copper coils within the pavement. These coils create a magnetic field that the Electron receiver can garner energy from, then the receiver transfers that energy to an EV’s battery and motors.

The project was partly funded by a $1.9 million investment from the Michigan Department of Transportation (MDOT). It also comes alongside an additional goal for the state to build a 40-mile “connected corridor” for EVs and self-driving vehicles, running from Detroit to Ann Arbor.

Electreon was initially founded in 2013, and the company currently has 18 different wireless EV charging roads across Europe and elsewhere. The projects wireless charging projects are actively happening in Sweden, Norway, Italy, Israel and a handful of other countries on the continent.

The road’s completion comes amidst debate about whether wireless EV charging will be a practical solution over the long term. Some have expressed that it may simply be more affordable for taxpayer money to go toward the expansion of regular EV chargers, while others have aired concerns around subjects like maintenance and efficiency of the roads.

Tesla sells wireless charging unit firm Wiferion, but keeps its engineers: report

En een ggl-vertaald stukje:

Het concept van draadloos opladen van elektrische voertuigen zal naar verwachting vooral nuttig zijn voor voertuigen die repetitieve routes gebruiken, zoals bussen, taxi's en vrachtvoertuigen, hoewel de verwachting is dat ze in de toekomst ook beschikbaar zullen zijn voor personenauto's.

De draadloze EV-oplaadtechnologie werkt via elektromagnetische inductie met behulp van ingebedde koperen spoelen in de bestrating. Deze spoelen creëren een magnetisch veld waar de elektronenontvanger energie uit kan halen, waarna de ontvanger die energie overbrengt naar de batterij en motoren van een EV.

Het project werd gedeeltelijk gefinancierd door een investering van $ 1,9 miljoen van het Michigan Department of Transportation (MDOT). Het gaat ook gepaard met een extra doel voor de staat om een ‘verbonden corridor’ van 64 kilometer te bouwen voor elektrische auto’s en zelfrijdende voertuigen, die loopt van Detroit tot Ann Arbor.
