Bye… Bye… Charging Stations Breakthrough Innovation: Toyota Trial Run Car Covered In Solar Panels

Future Electric Car

“Change is Inevitable”

The very appropriate word for the new innovation which is going to change the Electric Car market forever.

Toyota knows how to change the game when it comes to a new kind of innovation. Solar panels put together with great battery capacity. With years of experience in the car making, Toyota is ready to shake the market with this new beast.

With this innovation, the car becomes self-sufficient and self-propelled. It doesn’t require any charging stations.

Toyota Motor Corp., Sharp Corp., and the New Energy and Industrial Technology Development Organization of Japan, or NEDO, to test a Prius that could revolutionize transportation.

“The solar car’s advantage is that — while it can’t drive for a long-range — it’s really independent of charging facilities,” said Koji Makino, a project manager at Toyota.

Even if fully electric cars overtake petroleum-powered vehicles in sales, they still need to be plugged in, which means building a network of charging stations across the globe. The sun, on the other hand, shines everywhere for free, and when that energy is paired with enough battery capacity to propel automobiles at night, solar-powered cars could leapfrog all the new-energy technologies being developed, from plug-in hybrids to hydrogen fuel cell vehicles, in one fell swoop.

“This is not a technology we are going to see widely used in the next decades,” said Takeshi Miyao, an auto analyst at consultancy Carnorama. “It’s going to take a long time.”

A Prius plug-in hybrid that sells for more than ¥3 million offers solar panels as an option, but they only charge the battery when parked. The maximum amount of power for driving only lasts about 6 kilometers (about 4 miles), said Mitsuhiro Yamazaki, director at the solar energy systems division of NEDO.

Toyota has been testing a new solar-powered Prius since July, though it acknowledges that cars running nonstop without connecting to a hose or plug are still far away. Even so, the company said the research will pay off in other ways.

Indeed, there have been some breakthroughs, mainly due to advancements by Sharp. The prototype’s solar panel converts sunlight at an efficiency level of more than 34 percent, compared with about 20 percent for current panels on the market.

Because the solar cell being used by Toyota, Sharp and NEDO is only about 0.03 mm thick, it can be placed on more surfaces, including the curvy parts of the roof, hood and hatchback. The electrical system can charge the vehicle even when it’s on the move.

If the car is driven four days a week for a maximum of 50 kilometers a day, there’s no need to plug into an outlet, NEDO’s Yamazaki said.

Toyota’s bet on solar is one of many that Japan’s No. 1 carmaker is placing on the future of transportation. With Volkswagen AG and other auto titans facing uncertain futures as new technologies and business models ripple through the $2.23 trillion (¥240.8 trillion) global industry, they’re investing billions of dollars in cars powered by electricity and hydrogen to keep pace.

China has also explored efforts to tap the sun for transportation purposes. China tested an “intelligent highway” that buries solar panels, mapping sensors and electric battery rechargers under transparent concrete, with the photovoltaic cells generating enough electricity to power highway lights and 800 homes.

NEDO started the current project in 2016 with the goal of achieving an output of 1 kilowatt in vehicles by using a solar-battery module with a conversion efficiency of more than 30 percent. Sharp, one of Japan’s largest makers of solar panels, is developing the solar-cell technologies with NEDO funding, while Toyota is responsible for making the system to convert energy into driving power.

While the car’s greatest potential markets will be sunny climes, such as California and western China, NEDO will evaluate whether it’s also suitable for cities such as Tokyo, a key assessment for deciding whether to mass produce the vehicle, Makino said. The current trial is scheduled to run through March.

If the solar-powered Prius can be made, it could compete with established manufacturers such as Hyundai and startups Karma Automotive and Lightyear. The Lightyear One is a $170,000 luxury electric car that, according to its developers, can drive almost 500 miles on a single charge.

The startup, founded in 2016 by a group of Dutch engineering students, uses 54 square feet (5 square meters) of solar panels on the roof and hood that add more than 7 miles (11 kilometers) each hour to the car’s driving range. Production is planned to start in 2021, and more than 100 cars have been preordered, the company said.

Sharp’s solar cells more commonly are used for charging homes and satellites. Toyota’s demo car is covered by about 1,100 cells, each about the size of a business card, said Hiroyuki Juso, a senior manager at Sharp’s solar panel project. The expense of the cells makes mass production unlikely for now, he said.

“There is potential in this technology,” Carnorama’s Miyao said.
