The plug-free way to fill the world with e-vehicles

Umer Anwer stops on the street near Tesla Inc’s Brooklyn showroom and grabs his smartphone. He is looking for a spot to charge his electric car and the Tesla charging plugs do not work with the Nissan Leaf he is driving.

In fact, he would prefer not to bother with a plug at all.

Hevo Inc, the wireless-charging start-up where Anwer is chief technology officer, aims to overturn the burgeoning industry that is busy building out a global infrastructure to provide power to electric cars through public plugs.

There were about 582,000 public charging outlets worldwide at the end of last year, according to a report by Bloomberg NEF (BNEF), and that number is forecast to grow by nearly 30 percent this year.

Virtually every one of these charging locations uses plugs.

Anwer eventually maneuvers his electric car over a device that looks like a white plastic panel, then presses a button on a smartphone app.

After pulling into the parking space, blue dots flash under the windshield to indicate that power is flowing into his battery.

There is about 15cm of empty space between the charger and the car, which has been modified to receive power through an electromagnetic field.

This could represent the future of car charging. Suburban driveways, public spaces, parking lots and highway rest stops could all be tricked out with wireless ports to serve the tens of millions of electric cars expected to be on the roads over the next two decades.

Wireless charging, if it catches on, might provide a solution for one of the main questions hanging over electric cars: How can cities accommodate the infrastructure needed without cluttering up streets with posts and wires?

In cities like New York, London and Hong Kong, where parking is scarce, it is difficult to imagine where extra space can be made to accommodate idle cars while they recharge.

Hevo has raised US$4.5 million to date in a bid to solve that problem, with funding evenly split between venture capital and government grants.

After wrapping up 10 pilot projects across four countries and four US states, the seven-year-old start-up is now moving into manufacturing.

The company has set up shop in a factory in New York, where it plans to soon crank out its first 25 wireless chargers.

Hevo founder Jeremy McCool, a former US Army captain, spent 14 months in Iraq witnessing the consequences of energy geopolitics before enrolling in Columbia University to study sustainable development.

Hevo grew out of a school project.

“I started the company with no team, no technology and US$800,” McCool said in an interview. “Probably the worst and more naive way to start a company, by all means.”

The company plans to make thousands of devices in the next 18 months, the volume necessary to make good on the supply agreements he has signed with automakers and utilities.

Electric vehicles are projected to undergo explosive growth in the coming years.

The International Energy Agency has projected that the number of plug-in and hybrid cars on the roads would triple to 13 million by the end of the decade.

More than a quarter of all new cars sold annually would be electric by 2030, according to forecasts by BNEF, with the global ranks of electric cars reaching 30 million by then.

Of course, as things stand today, virtually all of these cars would need to be plugged into a socket before they could be charged. Before the world can adopt wireless charging, cars already on the road would need a retrofit and automakers would ultimately need to tweak their designs.

“The equipment on the vehicle is cheaper and more lightweight than existing plug-in charging equipment by a factor of five to 10 times,” McCool said. “We’re also future-proofing for autonomous electric vehicles. If you don’t need a human to park the car, you shouldn’t need to a human to charge the car.”

This technology could also potentially provide a solution to the issue of how to charge electric cars in densely populated cities.

Today, most drivers of the plug-in cars on the road almost always charge up at home. That requires a garage or a driveway.

Installing Hevo’s devices in apartment building parking lots and along residential streets could help open up new markets, from New York to Tokyo, where access to plugs can prove difficult.

“Wireless charging technology has improved steadily and can definitely make charging at home more convenient,” said Colin McKerracher, head of advanced transportation analysis at BNEF. “The most promising near-term applications are en-route charging for buses. For widespread adoption, several major automakers would need to fully back the technology.”

Brooklyn-based Hevo is working with three automakers, two top auto parts suppliers and three energy companies.

BMW AG is already selling a car with wireless charging capability:The 530e hybrid has been available in Germany since May.

Daimler AG, the maker of Mercedes-Benz cars, presented the technology as a charging solution when it launched its S-Class plug-in hybrid and Daimler spokesman Christoph Sedlmayr said the company would introduce it as soon as it is “technically fully developed.”

Wireless charging might threaten the conventional electric-vehicle charging industry that has already millions of US dollars.

Investment into companies building charging networks last year rose 165 percent to US$345 million, according to Cleantech Group.

Oil companies have made moves into charging to allay concerns about losing customers at gas stations.

Several European utilities, from Fortum Oyj of Finland to Innogy SE in Germany, are installing thousands of chargers in garages, parking lots and next to highways across the continent.

If it can be commercialized, technology like Hevo’s might some day shake up these plans.
