Every time I write about solar vehicles, I get the same thing from people in the comments and on social media, like:

“That’s a stupid gimmick that’ll add like a mile a day.”

“What a joke. That can’t even run the air conditioning.”

While these statements have been true for decades, solar technology and EV efficiency have slowly been chipping away at the problem. Now, vehicles like the “never charge” Aptera and the Sono Sion are proving that solar can power at least a good chunk of people’s driving — but can it work for larger vehicles?

The answer isn’t a hard “No” like it once was. The amount of “Yes” is on the rise, even for people who don’t want to drive a “clown truck.”

Earlier this month, Sono Motors worked with ARI to add solar to a 458 “Box Body” truck. While not a full-sized truck, or even a normal-sized truck, it’s still an incredibly useful little beast. In cities, at airports, or just for the last mile of package delivery, the 458 Box Body can carry almost 1200 pounds (531 kg) and up to 2.8 cubic meters (about 100 cubic feet) of cargo. It can go a maximum of 80 km/h (about 50 MPH) and has a range of 75–300 miles on a charge.

At full throttle, the 458 Box Truck uses only 7.5 kW of electric power, but most driving would be with far less current. So, it’s really an ideal platform to experiment with solar drive power.

Sono took the stock 458 Box Truck and added solar modules made with ultra-thin, chemically-stressed front glass to provide up to 450 watts of energy at peak performance. Under normal conditions in Munich, they figure that it will add 20 km of range daily without plugging in, and up to 45 km of range under more ideal conditions like you’d find in the US Southwest.

“Sono Solar — Sono Motors’ B2B unit — is a one-stop-shop for vehicle integrated photovoltaics (ViPV) and our aim is to make every vehicle a solar vehicle. The Intersolar exhibition is the perfect platform to show our proprietary technology and services and we are very pleased to be able to present existing partnerships and prototypes like the electric ARI transporter,” says Mathieu Baudrit, Sono Solar Group Lead at Sono Motors.

Fraunhofer Is Testing A Larger Solar Truck

When it comes to cargo trucks, Justin Hammer was right. Size does matter. Don’t let anyone tell you differently. In ‘Murica, we need a big 9,000 pound truck just to go to the store and buy kitty litter. Don’t believe me? Ask GM about the Hummer EV. Clown cars like the 458 Box Truck might be useful for the city parks and recreation department to drive around the baseball fields, or for the airport to stuff tiny meals into planes with, but don’t expect to see them on the road.

When it comes to doing a real man’s man work, we want to be like Rubber Duck in the 1978 movie Convoy. “My daddy always told me to be like a duck. Stay smooth on the surface and paddle like the devil underneath!” If we can’t push 80,000 lb down the road while strung out on caffeine and modafinil (among other things) while eating an echo-modded radio microphone and saying “Breaker one nine!” on 27.185 MHz AM with an illegal 600-watt linear amplifier that makes the lights go dim when you key it up, it’s just not good enough.

I’m kidding about most of the above, of course. While the Hummer EV does weigh in at 9,000 pounds, and we really do love our big vehicles, almost nobody even knows what most of the last paragraph even means. You’ll just have to watch the YouTube video and hang out at truck stops a little more to see if I’m making stuff up.

Many reasonable, sane people who wouldn’t ram the New Mexico State Police or the Illinois National Guard out of the way, and who want to carry cargo for an honest living, do really need a larger vehicle than the 458 Box Truck. Where’s the solar panel for us “Rubber Ducks?”

Fortunately, the industry is working on giving even the biggest trucks some juice from the giant thermonuclear fireball in the sky. Fraunhofer has an electric truck driving on German roads right now with 3500 watts of solar power on the trailer. Sure, it’s no 18-wheeler, but 18 tons GVWR is nothing to sneeze at either. The 3.5 kilowatts of power only takes care of 5–10 percent of the electric truck’s energy needs.

“By successfully putting our high-voltage photovoltaic system into operation, we have achieved our goal of demonstrating the feasibility of vehicle-integrated photovoltaics for heavy-duty electric utility vehicles. The technical components integrated into the truck function as we expected,” said Christoph Kutter, project manager at Fraunhofer ISE.

There is one small safety risk, though. To directly charge the truck’s traction battery, the panels are wired in series, and put out that 3500 watts of power at over 400 volts. In the event of an accident, that’s a lot of juice to be randomly flipping around in the face of emergency workers and good Samaritan types. Fraunhofer thought ahead and installed an automatic disconnect that cuts every solar panel off from the whole system, reducing the voltage down to safe levels.

Feeding 5–10% of the vehicle’s needs from solar might seem sort of silly, but Fraunhofer plans to run the truck hauling real loads for a year on German roads to collect data. By collecting the data on how much solar power ends up being generated, used, and replaced, they can get a much better idea of how to build better solar vehicles in the future as the technology improves.

After all, solar panels are getting better all the time, and it will eventually be possible to take care of a significant portion of the truck’s power. Plus, trucks operating in cities and trucks that spend a lot of time sitting during the day will benefit even more from this technology.

So, fear not, Rubber Ducks. The power of the sun will soon be yours!

Tesla now distinguishes cars by battery suppliers for tax credit eligibility

Tesla now distinguishes cars by battery suppliers for tax credit eligibility

Tesla is now distinguishing its cars between battery suppliers in order for people who are eligible for the tax credit to get it.

Electric vehicle manufacturers in the US are still adapting to the increasingly more stringent rules of the $7,500 federal tax credit for electric vehicles.

The increased requirements for more battery material and component sourcing have shuffled the eligibility of some vehicles, and for Tesla vehicles, it can change depending on the trim.

We recently noted that Tesla managed to get its Model 3 Long Range to get access to the full tax credit. Prior to that, its generally more expensive Performance variant would cost less due to access to the tax credit.

Now, Tesla has come up with an interesting solution to optimize the use of the cells so that more people can get access to the credit.

On its inventory page, Tesla has now added a new toggle for ‘Tax Credit Eligible Vehicles’:

Screenshot

What this toggle does is distinguish vehicles with Panasonic cells, which are eligible for the tax credit, rather LG cells, which are not.

This makes sense because the vehicle and the buyer need to be eligible. The eligibility criteria for buyers are $150,000 in individual income or $300,000 for dual filers.

If you don’t fit those criteria, it makes sense to get a car that doesn’t have those cells since you won’t get the credit anyway.

Electrek’s Take

This is a great idea to optimize access to the tax credit. However, it leaves people who are not eligible with a choice because, technically, the Panasonic cells are a little more desirable even without the credit.

They are known to charge a little faster than the LG cells.

It’s not a huge difference, but it’s something that people should at least know about before buying.

Rivian (RIVN) talks R2, cost-cutting, and more during 2024 Investor Day: Here's the latest

At its first Investor Day on Thursday, Rivian gave several insights into the EV maker’s future. CEO RJ Scaringe explained how Rivian’s software-defined EVs, built from the ground up, and other in-house tech are evolving for its next-gen vehicles.

Check out the latest from Rivian’s 2024 Investor Day below.

The next growth stage

Rivian held its first Investor Day on Thursday. In a Tesla-like presentation, Scaringe outlined Rivian’s roadmap to profitability.

A Rivian is not just any other vehicle. Rivian’s Adventure Vehicles were built from day one to improve over time. “On day 300, it’s a better vehicle,” Rivian’s CEO said during the event.

Perhaps, more importantly, Rivian is learning to build them at a “significantly” lower cost, passing the savings onto buyers.

After building an authentic luxury EV brand, Rivian is making its vehicles more accessible. Rivian shut down its Normal, IL plant in April to improve efficiency. Scaringe said the updates and supplier negotiations have resulted in “significant cost improvements.”

The company cut out 100 steps from its battery-making process, over 50 components from the body shop, and 500 parts from the design.

Its focus on a scalable, flexible platform, built from the ground up, is paving the way for its future EVs.

Rivian outlines R2, future plans during 2024 Investor Day

Rivian introduced its smaller, cheaper R2 electric vehicle in March. Starting at $45,000, Rivian’s R2 is nearly half the cost of the R1S and R1T models.

After scoring over 68,000 reservations in less than 24 hours, Rivian’s R2 is expected to significantly expand its market.

Rivian’s R1S is already one of the top-selling EVs. Through the first three months of 2024, Rivian’s R1S was the fourth top-selling EV in the US, behind only Tesla’s Model Y, Model 3, and Ford’s Mustang Mach-E.

According to Scaringe, it’s also the top-selling large vehicle in California, electric or gas. The tech and features driving demand will translate to a lower price point in the R2, R3, and beyond.

Rivian is consolidating ECUs, harness length, and electrical parts to cut costs. In addition to supplier negotiations and more efficient manufacturing, Rivian is confident R2 will help drive profits.

Rivian plans to begin R2 production in Normal in early 2026. Although initially Rivian planned to build R2 at its new GA plant, the move will help save $2.25 billion. More importantly, it will help get R2 to market earlier.

The new partnership with Volkswagen shows the flexibility of Rivian’s platform. Rivian’s head of software, Wassym Bensaid, said the platform can be scaled up or down for more variants.

Bensaid explained how Rivian is focused on getting its software and hardware into more EVs globally. With software at the heart, Rivian’s vehicles will continue improving over time.

Since launching, Rivian has rolled out more than 30 OTA updates, adding over 500 features. It continues to take feedback to add new features like Snow Mode and Launch Mode.

Rivian’s platform enables continuous improvement and can be used for new functions, like autonomy. Using AI and machine learning, the software constantly takes in information, analyzes it, and improves via OTA updates.

Scaringe explained how Rivian’s new Enduro and Ascend drive units, built in-house, are driving down costs while improving performance.

The new Ascend motor is paving the way for future improvements for the R2 and further generation vehicles.

Maximus, or “Enduro Gen 2,” the drive R2 and R3 drive units, is focused on cost savings with less labor and parts. The side-mounted inverter optimizes packaging.

Rivian has also significantly reduced the number of parts to support lower costs. For example, the R2 has 65% fewer parts than the R1S.

Despite its cheaper price point, the EV maker promises that R2 will still have the essence of a Rivian.

The EU has revised its proposed tariffs on Chinese EVs… but only in the slightest

The EU has revised its proposed tariffs on Chinese EVs... but only in the slightest

A new report states that the European Union has slightly tweaked its proposed tariffs on imported EVs from certain Chinese automakers after those companies divulged more details of their businesses. The tariff cuts are marginal but could offer a shred of hope that the EU is still willing to negotiate said duties before they are imposed next week.

Another week, another chapter in the ongoing bluster of a potential trade war following proposed tariffs by the EU on Chinese-built EVs entering the region.

You probably know the backstory by now. The EU Commission opened an anti-subsidy probe into Chinese EV imports, deeming them unfair in competition, threatened new tariffs, the US imposed tariffs of its own quadrupled to 100%, etc.

Last we reported, Canada had joined the fracas, mulling tariffs on Chinese EVs to align with its US and EU trade partners. Meanwhile, China’s Ministry of Commerce had criticized the EU Commission’s anti-subsidy probing, claiming the requested details from foreign automakers were “unprecedented” and compared the probe to spy-like levels of inquisition.

Earlier this month, China’s Ministry of Commerce met in Beijing with several automakers subject to the EU probe, including state-owned SAIC and BYD. The meeting also included European automakers like BMW, Volkswagen, and Porsche, who have tried to help find a solution to avoid the Chinese government’s threats to “adopt firm countermeasures” and raise a provisional tariff on imported gasoline cars from the EU.

In a recent report, the EU has eased its proposed tariffs for some Chinese EV automakers, but only by mere percentage points.

China tariffs

EU reduces proposed tariffs for SAIC and Geely

According to a recent Bloomberg report, the EU has reduced some tariffs on Chinese EVs after receiving more information from automakers as part of its anti-subsidy probe. The news comes from someone familiar with the matter who spoke under the condition of maintaining anonymity.

Per the report, the following Chinese automakers will see reduced duties on EVs imported into the European market:

  • SAIC: 37.6% (Previously 38.1%)
  • Geely Automobile Holding: 19.9% (Previously 20%)

As you can see, the reduced tariff percentages are marginal but better than nothing, we suppose. The revised proposed tariffs will add to the existing 10% duty in the EU and apply to the other Chinese automakers—those who cooperated with the anti-subsidy and those who didn’t. Those proposed tariffs are an additional 20.8% (weight average duty) and 37.6% levy, respectively.

Rising EV automaker Build Your Dreams (BYD) was also mentioned in the EU tariff reduction report but will see no change to its proposed duties, which will be 17.4% if and when those tariffs take effect next.

Both China and the EU are reportedly still in talks at the negotiating table, and it appears the former is now settling for a bartered compromise rather than a complete abolishment of the new tariffs. We will keep a close watch on this ongoing story as the EU’s proposed tariffs are scheduled to initially go into effect on July 4 before definitive duties kick in this fall.
