During the Q2 2021 Earnings Call Update Letter released in late July, Tesla revealed that the Semi program would be delayed once again due to battery cell constraints and supply chain bottlenecks. However, developments regarding the Semi’s charging system still move forward, and one document from Ideanomics subsidiary WAVE proposes an extreme fast-charging system that would provide speeds of 500 kW and 1 MW. It would be void of cables, wires, and implanted directly into the roadway, providing power without having to plug in.

WAVE, an acronym for Wireless Advanced Vehicle Electrification, is owned by NASDAQ-listed company Ideanomics. WAVE develops high-power inductive charging solutions, but not for things like cell phones. They develop these charging systems for medium and heavy-duty vehicles, and the Tesla Semi may be one of the first vehicles to utilize the technology.

In the document, WAVE shares that extreme fast-charging systems are a sub-category of the company’s primary 250 kW business. However, it aims to develop 500 kW and 1 MW-capable wireless electric vehicle chargers for large-scale commercial vehicles using a primary coil embedded in the roadway and a receiving coil within the truck. Power would then be transferred using magnetic fields that are created by using a resonant inverter to create high-frequency AC currents to energize a charging coil. The energy from the coil underground would transmit energy to the truck, providing a charge without plugging in.

WAVE specifically mentions the strengths of the system and how it could benefit the Tesla Semi, in particular. The document states:

“The current state-of-the-art drayage truck charging features primarily conductive chargers. The recently announced Tesla Semi concept design has the largest advertised range of 500 miles with a target 80% charge in 30 minutes. The battery pack is estimated to be at least 800 kWh (likely much higher to cover full load and all conditions) and must have a target charge rate of at approximately 1.5 MW. The system under development via the US DOE contract of charging an electric drayage truck at extreme fast-charging power levels will be the fastest charger by a significant margin.”

This will be possible through WAVE’s recently-developed wireless charging system that can transfer up to 250 kW for bus charging at a distance of 250 millimeters, or 10 inches. “This is achieved by using a scalable modular approach. For this project, WAVE will increase the power level to 500 kW.”

WAVE can achieve the increased power level by increasing the power rating and density of the electronics and the coil design. Uses for the idea can be applied to “a number of urban applications,” and WAVE indicates that it won’t be a technology exclusive to Class 8 vehicles.

Tesla has been developing the Megacharger for the Semi for several years and has achieved some impressive specs ahead of the vehicle’s release. In 2017 at the Semi’s unveiling event, CEO Elon Musk said that Tesla would install a global network of solar-powered Megachargers that could provide 400 miles of range in just 30 minutes. An output of over 1 MW would make this possible, but to avoid potential dangers due to high energy output, Tesla filed for liquid-cooled charging connectors. Tesla uses something similar in its V3 Superchargers.

Yesterday, WAVE was awarded a contract to develop wireless inductive charging solutions by government organization Sourcewell.

Elon Musk echoes worries over Tesla control against activist shareholders

Elon Musk has spoken on several occasions of the “activist shareholders” who threaten his role at Tesla.

Elon Musk continues to raise concerns over his control of Tesla as its CEO and one of its founders, as activist shareholders seem to be a viable threat to the company in his eyes.

Musk has voiced concerns over voting control of Tesla and the possibility of him being ousted by shareholders who do not necessarily have the company’s future in mind. Instead, they could be looking to oust Musk because of his political beliefs or because of his vast wealth.

We saw an example of that as shareholders voted on two separate occasions to award Musk a 2018 compensation package that was earned as Tesla met various growth goals through the CEO’s leadership.

Despite shareholders voting to award Musk with the compensation package on two separate occasions, once in 2018 and again in 2024, Delaware Chancery Court Judge Kathaleen McCormick denied the CEO the money both times. At one time, she called it an “unfathomable sum.”

Musk’s current stake in Tesla stands at 12.8 percent, but he has an option to purchase 304 million shares, which, if exercised, after taxes, he says, would bump his voting control up about 4 percent.

However, this is not enough of a stake in the company, as he believes a roughly 25 percent ownership stake would be enough “to be influential, but not so much that I can’t be overturned,” he said in January 2024.

Musk’s concerns were echoed in another X post from Thursday, where he confirmed he has no current personal loans against Tesla stock, and he reiterated his concerns of being ousted from the company by those he has referred to in the past as “activist shareholders.”

Elon Musk explains why he wants 25% voting share at Tesla: “I just want to be an effective steward of very powerful technology”

The CEO said during the company’s earnings call in late July:

“That is a major concern for me, as I’ve mentioned in the past. I hope that is addressed at the upcoming shareholders’ meeting. But, yeah, it is a big deal. I want to find that I’ve got so little control that I can easily be ousted by activist shareholders after having built this army of humanoid robots. I think my control over Tesla, Inc. should be enough to ensure that it goes in a good direction, but not so much control that I can’t be thrown out if I go crazy.”

The X post from Thursday said:

There is a concern that Musk could eventually put his money where his mouth is, and if politicians and judges are able to limit his ownership stake as they’ve been able to do with his pay package, he could eventually leave the company.

The company’s shareholders voted overwhelmingly to approve Musk’s pay package. A vast majority of those who voted to get Musk paid still want him to be running Tesla’s day-to-day operations. Without his guidance, the company could face a major restructuring and would have a vastly new look and thesis.

People are already finding value in Tesla Robotaxi services

Tesla initially launched its Robotaxi service in Austin, though the company more recently launched it in the Bay Area.

Tesla’s Robotaxi service is still in its earliest days, but some consumers are already finding surprising value in the autonomous ride-hailing system. 

This was hinted at in recent comments on social media platform X. 

Robotaxi Ramp

Tesla initially launched its Robotaxi service in Austin, though the company more recently launched it in the Bay Area. Tesla’s geofence for its Robotaxi service in the Bay Area is massive, covering several times the area that is currently serviced by rival Waymo. 

As noted by the EV community members on social media, going end-to-end in Tesla’s Bay Area geofence would likely take over an hour’s worth of driving. That’s an impressive launch for the Robotaxi service in California, and considering Tesla’s momentum, its California geofence will likely grow substantially in the coming months.

Secret Advantage

As noted by Tesla owner and photographer @billykyle, the Tesla Robotaxi service actually has key advantages for people who travel a lot for their work. As per the Tesla owner, using a Robotaxi service would give back so much of his time considering that he gets about 5-7 shoots per day at times.

“I’ve been reflecting on how much of a game changer this is. As a photographer that runs my own business, servicing clients all around the Philadelphia area, I could ditch having a car and let an autonomous vehicle drive me between my 5-7 shoots I have per day. This would give me so much time back to work and message clients,” the photographer wrote in a post on X.

The Tesla owner also noted that the Robotaxi service could also solve issues with parking, as it could be tricky in cities. The Robotaxi service’s driverless nature also avoids the issue of rude and incompetent ride-hailing drivers, which are unfortunately prevalent in services such as Uber and Lyft. Ultimately, just like Unsupervised FSD, Tesla’s Robotaxi service has the potential to reclaim time for consumers. And as anyone in the business sphere would attest, time is ultimately money.

Tesla Robotaxi and Supercharger Diner are killing a dreaded consumer tradition

Tesla is still just charging strictly for its services–while asking for zero tips.

Tesla’s Robotaxi service and its newly launched Supercharger Diner are killing a longtime but increasingly dreaded consumer tradition in the United States. Based on videos taken of consumers using the Robotaxi service in the Bay Area, Tesla is still just charging strictly for its services–while asking for zero tips.

Tesla Services with Zero Tips

When Tesla launched the Robotaxi pilot in Austin, users quickly noticed that the company was not allowing riders to leave a tip for the service. If one were to try leaving a tip after a Robotaxi ride, the app simply flashes an image of Tesla’s meme hedgehog mascot with a “Just Kidding” message. 

At the time, this seemed like a small tongue-in-cheek joke from the electric vehicle maker. The initial Robotaxi pilot in Austin was rolled out on a small scale, after all, and some social media users speculated that tipping may eventually just be introduced to the service.

But upon the opening of the Tesla Supercharger Diner, consumers also observed that the facility does not allow tipping. Tesla’s notice is simple: “Gratuity: Tesla covers tipping for staff.” This means that employees who work at the Tesla Diner make enough to not rely on gratuities from consumers. 

And with the launch of the Robotaxi service in the Bay Area, users observed once more that Tesla is still not allowing tipping. This was highlighted by longtime Tesla owner @BLKMDL3, who shared a video of the Tesla Robotaxi app also briefly displaying the hedgehog mascot with a “Just Kidding” message when he tried leaving a tip.

Out of Control

As noted in a report from The Guardian, tipping has been a longstanding business practice in the United States, were service workers typically make less than the federal minimum wage. With this system in place, service workers end up relying on gratuities to make ends meet. This was understandable, but after the pandemic, tipping culture ended up going out of control.

On platforms such as Reddit, users have also complained about services like Uber asking for large tips for using their services. Consumers have also shared shocking experiences involving some services that ask for tips. These include self-checkout counters, drive-throughs, hotdog stands, drug stores, a bottled water stall at a jazz festival, an airport vending machine, a used bookstore, a cinema box office, and a children’s arcade, among others.
