Tesla Semi battery weight criticisms are rooted in outdated ideas: EV expert
A good number of skeptics critical of battery-electric long-haulers like the Tesla Semi typically argue that the weight of the vehicles’ batteries makes them ineffective against competitors that are powered by diesel or hydrogen. As noted by an electric vehicle veteran and expert recently, however, these ideas are rooted in outdated ideas about battery weight. And if one considers more recent battery tech, electric Class 8 trucks may not only be feasible; they may actually be closer than expected.
In a recent piece on Bulk Distributor Magazine’s November/December 2020 issue, Auke Hoekstra, Senior Advisor for Electric Mobility at the Eindhoven University of Technology, noted that contrary to popular belief, long-haul trucks would not be the last vehicles to become battery-powered. This is in no small part due to the advancement of battery technology. Hoekstra noted that within five years, he believes that “electric trucks will become the logical choice for many bulk transporters” And within 10 years, vehicles like the Tesla Sei will likely dominate new sales.
The stunning progression of battery technology could be seen in just how much batteries have gotten better and cheaper over the years. Hoekstra noted that myths about electric trucks being too heavy were true 20 years ago, but not today. If electric long-haulers existed 20 years ago, they would likely be powered by lead-acid batteries, and assuming a battery size of 1 MWh, such a vehicle will require a pack that will likely weigh about 25 tons. That’s more than the entire payload of the truck. This is, of course, not the case today.
Hoekstra noted that when he wrote his first book about electric vehicles for the Dutch Ministry of Road Transport 13 years ago, lithium-ion batteries had started to emerge. Lithium-ion batteries offered reductions in weight, resulting in a 1 MWh pack weighing only about 10 tons. Today, this is even better, with modern electric cars having batteries that weigh about 5 kg per kWh or 5 tons per MWh. “I expect that with five years, that weight will be down to 3.5 tons. And it doesn’t stop there,” the EV veteran wrote.
Class 8 trucks like the Tesla Semi, which are designed from the ground up to be electric, will likely offer even better weight advantages. Hoekstra estimated that Tesla would see further weight reductions of about 2.5 to 3 tons due to the vehicle’s all-electric platform. “The electric motor is lighter, and you can get rid of the diesel tank and exhaust treatment. Then you place the electric motors between the wheels and lose the differential, driveshaft, and a host of other components,” he wrote.
What’s particularly interesting is that these estimates don’t even take into account the innovations that Tesla unveiled in its Battery Day event. Once Tesla’s 4680 tabless cells and structural battery packs enter the equation, the Semi becomes an even more compelling alternative to diesel-powered trucks. Hoekstra estimated that Tesla’s structural battery packs could save another ton to the Semi’s overall weight, seeing as the battery would practically displace the steel beams that give traditional Class 8 long-haulers their rigidity. With this in mind, the EV veteran noted that “battery weight will soon be a problem of the past.”
There are other advantages to electric trucks that were highlighted by Hoekstra in his piece, such as the cost savings that will result from the use of a fleet of electric trucks. This is something that Tesla has highlighted in the past, with CEO Elon Musk stating during the vehicle’s unveiling that the Semi will vastly undercut diesel-powered rivals when it comes to operating costs. Couple this with the low maintenance requirements of EVs, as well as the fact that batteries now last much longer, and trucks like the Tesla Semi will likely become very attractive options for operators in the very near future.
Lucid CEO Silvio Napoli responded to rumors of an imminent bankruptcy that was reportedly being mulled after a report stated the automaker was working with the firm AlixPartners to iron out its next steps.
The company felt a massive loss on Wall Street yesterday, as the report essentially pushed the stock down as much as 55 percent on Tuesday.
The report, published initially by Eletric-Vehicles.com, claimed Lucid was essentially in dire straits and was told by AlixPartners, a commonly used restructuring advisor, to either take shares private or file for Chapter 11 bankruptcy protection.
Lucid’s head of Communications, Nick Twork, immediately challenged the report and stated the company “has sufficient liquidity to carry its operations well into next year.”
Now, the company’s CEO is chiming in as well, stating that the report is “so far from the facts that they require a direct response.”
Napoli said:
“Lucid is not considering bankruptcy or a transaction to take the company private. Those reports are false. The Board did not explore either scenario. Period.
As disclosed in our most recent quarterly filing, Lucid has sufficient liquidity to fund its operations well into next year.
We work with outside advisors to improve operational performance and execution. They are not advising Lucid on a take-private transaction or bankruptcy, and any suggestion that they have recommended either course of action to management or the Board is false.
My priority is clear: turn this company around. That is where the leadership team and I are focused.
I look forward to providing a full update during our quarterly earnings call on August 4th.”

It seems pretty clear that Lucid is confident things will be okay, and, to be honest, they should not have much to worry about, especially considering the company has been backed by the Saudi Public Investment Fund (PIF) for years. It has solid financial backing, and its sales, while weak, are pretty much right on par with a company of this age.
Lucid also sent a Cease & Desist letter to the publication for their report.
Lucid shares have rebounded nicely and are up nearly 21 percent at the time of publication. As soon as the company dispelled the rumors of bankruptcy yesterday, the stock began to climb back toward more reasonable levels.
Tesla has once again demonstrated strong customer focus by swiftly addressing and fully refunding a bizarre Supercharger pricing glitch that affected drivers in Atlantic Canada.
The issue surfaced earlier this month when the Tesla app began displaying dramatically inflated per-minute charging rates at stations in Prince Edward Island and parts of New Brunswick.
One widely shared screenshot from a Charlottetown, PEI Supercharger showed rates reaching ridiculous levels: $6.00 per minute for the 180-250 kW tier, along with $3.57/min for 100-180 kW and $2.29/min for 60-100 kW.
Correct pricing will be going live at midnight tonight. All fees since July 2nd 2026 will be waived.

These figures were several times higher than normal Supercharger pricing in the region.
To put the error in perspective, charging at the highest incorrect rate would have been shockingly expensive.
At 250 kW, a common charging speed at Superchargers, a vehicle pulls roughly 4.17 kWh per minute. Under the glitch, a driver spending just 10 minutes at peak power would face a $60 bill. A typical 20- to 30-minute session to add meaningful range could have cost $120 to $180 or more, before any congestion fees.
Tesla gets another layer of gamification with Free Supercharging on the line
By comparison, standard Canadian Supercharger rates usually fall between $0.25 and $0.60 per kWh, making a similar session cost roughly $15–$40. The erroneous per-minute structure, combined with the inflated numbers, turned what should be a convenient stop into a potential financial shock.
The glitch appears to have started sometime around early July, and quickly drew attention on social media as owners questioned whether Tesla had implemented steep hidden increases. Some drivers even reported seeing $0 charges in their history, indicating broader billing confusion.
Tesla’s official Charging account on X stated that correct pricing would roll out at midnight on July 13, so the fix is already in effect. More importantly, the company announced it would waive all fees for every Supercharger session since July 2. This blanket waiver covers the entire affected period without requiring users to file individual claims, with automated refunds expected soon. The decision affects stations in PEI and nearby areas in New Brunswick and Nova Scotia.
It’s a classy move, and rather than issuing partial credits or forcing owners to submit support tickets, Tesla simply absorbed the cost of the system error and made drivers whole. In an industry where hidden fees and bill disputes are common, Tesla’s proactive, no-questions-asked approach reinforces owner trust and highlights the company’s commitment to service excellence.
The incident, while disruptive for a short time, ultimately showcases Tesla’s ability to own mistakes and prioritize customer satisfaction. Atlantic Canada Tesla owners can now charge with confidence again, knowing the company has their back when technology glitches occur.
In an era of complex EV billing, such transparency and generosity are refreshing and set a positive example for the industry.
