Are Solar Panels the Future of Electric Vehicles?

As electric cars go mainstream, the auto market has mainly attained the consensus that the future big issue is no lengthier about eliminating gas engines, but discovering the most effective technique to deliver electric power to power automobiles. Some businesses, which includes Tesla, concentrate on perfecting the by now well known lithium-ion batteries some others just take the threat to check out new battery tech these kinds of as hydrogen gas cells and reliable-condition batteries.

But several have pursued an different energy resource that dominates elsewhere: photo voltaic electrical power.

What is stopping EV businesses from earning a automobile wrapped in photo voltaic panels that can automatically demand by itself up when it is sunny outside and then have adequate juice to hit the street the following early morning? The concept seems basic sufficient and completely environmentally friendly.

In truth, there were being some early tries at harnessing the sun’s strength for automobiles. In 1955, a Normal Motors engineer built a tiny, 15-inch-extensive photo voltaic car or truck, dubbed the Sunmobile, to exhibit the choices of photo voltaic power. Regretably, they have been unable to construct out the prototype into a completely photo voltaic-driven vehicle owing to limits in electrical power performance, storage and (clearly) climate. And considering the fact that, engineers have arrive to the summary that no photo voltaic panel can create sufficient power to assist a car’s standard use while getting smaller plenty of to be carried about by a motor vehicle.

But Laurin Hahn, the founder and CEO of German startup Sono Motors, thinks that the idea is however truly worth discovering. His strategy is intuitive: making use of solar at greatest by wrapping an complete car in solar cells.

“People will generally say it’s a gimmick. But it is not. Solar provides down prices and makes EV extra reasonably priced without sacrificing the ease,” Hahn explained to Observer in an job interview very last thirty day period.

At this year’s (digital) Purchaser Electronics Clearly show in January, Sono unveiled its newest prototype SEV (photo voltaic electric auto), a passenger car referred to as Sion. The corporation also showcased a trailer outfitted with Sono’s solar human body panels to exhibit the technology’s prospective to be integrated into other cars.

At 1st glance, Sion doesn’t glimpse significantly unique than any other black compact car roaming the streets in European metropolitan areas. But on closer inspection, it gets clear that the car’s exterior is manufactured up of hundreds of solar cells molded into polymer. These solar cells (which complete 248 in all) transform sunlight into electricity, which is then saved in the vehicle’s battery. Dependent on ordinary climate in Munich, solar cells on a Sion can crank out up to 1.2 kilowatts a working day, which interprets into 21 miles of driving variety. That alone is adequate for most commuters in Europe, who on typical travel 11 miles a working day.

In The united states, men and women travel a bit additional (average 30 miles a day), but also very likely are living in spots that have extra sunny days than Munich.

Still, it is nonetheless not quite a entirely photo voltaic-electric power automobile. Merged with its crafted-in lithium-ion battery, a Sion can previous for 155 miles on a one charge at a most speed of 140 km/h (87 mph).

But Sono’s solar panels aren’t built to exchange conventional charging techniques in any case, Hahn pressured. Alternatively, it’s meant to be a energy complement to minimize a battery car’s reliance on charging infrastructure. In Germany, for instance, the place commuters travel 10 miles each day, solar integration in the Sion motor vehicle extends the need to have to plug in from once a 7 days to once a month.

The much larger function is to integrate the engineering into the rest of the transportation field. “We have a two-fold aim: to establish an cost-effective mass-market SEV and to make this know-how out there to other battery-run vehicles, trains, boats, essentially any moving point that consumes electric power,” Hahn spelled out.

“We have enormous desire from refrigerated vans, for case in point,” additional Thomas Hausch, Sono’s chief working officer. “The trailer business has huge strain to go towards zero-emission. And we have identified a alternative for them that’s feasible and economical.”

In January, Sono struck a offer to license its photo voltaic know-how to EasyMile, a French business earning electrical autonomous shuttle buses. Not disclosing names, Hahn said the firm is in talks with quite a few U.S. automakers “that have a ton of vehicles on the highway,” and “they are hugely interested.”
