There may come a day when topping up your EV’s battery is as simple as driving down the road.

In the meantime, Israeli startup Electreon is making progress toward introducing wireless EV charging to what its leaders see as the best segment to lead the way on this emerging tech: commercial fleets.

The state of Michigan recently announced an expansion of its wireless charging partnership with Electreon to provide charging solutions to a UPS fleet in Detroit. As Tech Brew previously reported, Electreon started testing its tech on a quarter-mile portion of road on the Michigan Central campus in Detroit, with support from the state, about a year ago.

Electreon will integrate its charging tech into an electric van assembled by commercial EV manufacturer Xos, according to a news release, and the companies will install stationary, cable-free charging equipment at a UPS facility.

The project stakeholders said in the release that this deployment could help prove out wireless charging tech’s “potential to lower the total cost of ownership in the electrification of commercial truck fleets.”

“We’re excited to demonstrate how Electreon’s technology can optimize electric fleet usage and showcase the seamless integration of wireless charging into daily fleet operations, minimizing downtime and enabling charging across time and location,” Stefan Tongur, Electreon’s VP of business development for the US, said in a statement.

No wires needed: The idea behind wireless (or inductive) charging is essentially to make charging a forgettable experience: Drivers don’t have to worry about plugging in and can even boost their range on the go.

Stakeholders like Tongur also have noted advantages like potentially being able to reduce battery sizes—which make up a significant portion of the cost of EVs—because drivers wouldn’t need as much range if they’re able to charge while they’re literally on the road (the tech has skeptics, too, who point to challenges like the massive investment and coordination it would require to rebuild portions of roadways).

For Electreon’s pilot project in Detroit, copper coils were installed under the road surface. The coils attach to a receiver that’s built into the vehicle. A magnetic field enables the roadway to transfer electricity to the vehicle’s battery.

The project was touted as the first public wireless charging roadway in the country. The aim was to determine whether it’s feasible to equip public roads with wireless charging capabilities, as part of a five-year agreement the startup has with the state.

Tongur said at the time, though, that Electreon’s near-term focus would be on commercial applications of its technology until it’s scaled up enough to support projects that would serve the mass market.

“We’re not going to the private passenger cars yet, because fleets are predictable in their behavior of where they drive,” he told Tech Brew previously. “They represent for us a very good go-to-market segment. That might be buses, heavy-duty trucks, last-mile delivery vehicles, shuttles.”

Businesses and fleet operators face a different calculus than retail consumers about making the electric switch. It has to make financial sense from the jump and deliver total cost-of-ownership benefits, even as businesses navigate shifting regulations. Fleet operators also are heavily focused on factors like where and how they’ll charge EVs and which commercial EVs make the most sense for their businesses.

“By doing those kinds of target segments first and getting those users’ fleets on board, we’ll also get the vehicles on board,” Tongur told us earlier this year. “We get the policymakers on board. We get the DOTs on board. And then we can scale this” to other use cases.

EV range anxiety could be a thing of the past thanks to Mercedes’ new solar paint – which promises thousands of free miles a year

  • Mercedes has unveiled a series of future innovations during workshops
  • Its ‘solar paint’ contains no rare earths and no toxic materials
  • Aerodynamic braking and power converters aim to improve EV efficiencies

The utopian dream of solar-powered motoring might not be so distant, as Mercedes-Benz recently opened the doors to some of its most forward-thinking engineering laboratories – and it turns out photovoltaic surfaces are very much on the agenda.

During a number of workshops in its home city of Stuttgart, Germany, Mercedes-Benz lifted the lid on how it has been working on a new kind of solar surface that could generate enough electricity for folks in sunnier climates to cover their daily commuting requirements.

According to the German marque, the ‘solar modules’ measure just five micrometers in thickness – significantly thinner than a human hair – and weigh just 50 grams per square meter. They can be applied to almost any substrate, with applications of future vehicles likely coming in the form of a “wafer-thin layer of paste” that will cover most of the body work.

Mercedes-Benz has past experience with solar panels and the impact they can have on the electric range of EVs, as the company’s record-breaking EQXX concept (the rolling lab that drove more than 620 miles on a single charge) used a small solar panel on the roof that added around 30km (18 miles) of additional range during one of its long distance record attempts.

But the breakthrough in photovoltaic surface treatments means much more of a vehicle could be covered, equating to a much greater increase in additional EV mileage.

Taking a fairly standard mid-sized SUV like the marque’s EQS as an example, Mercedes engineers claim the 11 square meter surface area and the 20% solar efficiencies of the technology would be enough to generate around 7,400-miles of motoring per year in somewhere sunny, like Los Angeles.

Nanoparticle-based paint would also allow 94% of the sun’s energy to pass through to the solar coating, meaning future EVs won’t necessarily have to look like giant solar panels.

Studying the daily driving habits of EV owners in Stuttgart, Germany, those close to the project found they cover an average of 52 kilometers (around 32 miles) a day. Around 62% of this distance would be covered using solar energy, the company says, despite the often poor weather conditions.

Again, if you live somewhere with plenty of excess sunshine, the ‘always-on’ nature of a photovoltaic surface means the vehicle could effectively be charging, even when parked.

As a result, LA owners could cover 100% of their driving distance on average by solar energy. Any surplus achieved could be fed directly into the home network via bidirectional charging, in theory.

Braking down inefficiencies

Alongside pondering the state of future cities and speeding up AI decisions with neuromorphic computing, Mercedes-Benz also touched on the fact that it is also working on an EV braking system that removes the need for standard discs, drums and pads.

Effectively ridding the world of harmful particles emitted in the form of brake dust, Mercedes’ innovation is integrated into the electric drive unit at the front or rear axle, negating the need for in-wheel brakes.

Not only would this be subject to minimal wear and take up less space, it would also mean the company could look at much lighter wheel and tyre combinations, reducing the overall mass of an EV, as well as exploring fully-enclosed rims for optimized aerodynamics, as openings for brake cooling would no longer be required.

Plus, the company’s research into electrical inverter systems could see the integration of micro-converters directly at battery-cell level, which would allow for greater control over individual cells.

It is complicated stuff, but it would result in more efficient battery performance, increased the longevity of battery pack lifespans and greater freedom when it comes to packaging – allowing engineers to use varying cell designs throughout the vehicle.

All of these advancements are still a long way from making production, but it is good to see Mercedes-Benz busy exploring innovations that offer its future customers real-world value.
