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.

Tesla has launched a new Vehicle-to-Load (V2L) Outlet Adapter for Premium Model Y vehicles in the United States, meaning you can now power devices like laptops or light strings with your vehicle’s battery.
It appears the capability will be available for any Model Y Premium trim, including those that were purchased prior to the Adapter being launched. It will also only impact Juniper Model Y vehicles, so the first-gen owners will unfortunately not have access to this capability.
If your Model Y was purchased before Tesla renamed the trim levels to “Premium” and “Standard,” it does not seem to be compatible. My Model Y is technically a Premium build, as it is the Long Range All-Wheel-Drive. However, Tesla says it is not compatible with my vehicle.
🚨 Tesla has launched the Outlet Adapter for Model Y Premium in the U.S., enabling V2L capability for all Premium trims (that’s what it appears to be as it is available for purchase with all Premium trims)
It’s available for $80. 2.4kW max power and rated for 120v, 20A pic.twitter.com/lDxlVIk5s8

For $80, you can now utilize your car as a portable charger for small appliances or devices. This is perfect for things like tailgates, concerts, or camping, as you can now plug in devices that you might use. Those string lights for camping? That laptop for the other games that are on at the tailgate?
-
They’ll both utilize energy from your Tesla’s battery to be powered. This is the first time Tesla has expanded the capability to vehicles outside of the Model Y Performance and Cybertruck. However, this feature has been highly requested by owners for an extended period of time.
Tesla launched the Outlet Adapter in China last year:
Tesla China rolls out Model Y L V2L adapter, and it’s free for early owners
You will need the Mobile Connector to operate the Outlet Adapter: the Outlet Adapter will plug into the main housing of the Mobile Connector, where the appropriate adapter to charge your vehicle will plug in.
It is rated for 120 volts and 20 amps, and has a max power rating of 2.4kW.
You can buy it here from Tesla for $80.

Tesla is nearing its long-awaited unveiling of the all-electric Tesla Roadster, a new report from The Information claims, as the company has said several times this year that the event would take place “soon.”
Now, it appears there is movement on Tesla’s end regarding when it will happen.
The report says that Tesla will unveil the Roadster as soon as this month with a SpaceX version that will utilize cold-gas thrusters to help the vehicle float for a short period of time. This is something CEO Elon Musk has talked about with the Roadster for years.
🚨 The Information is reporting this morning that Tesla is ready to unveil the “flying” Roadster as soon as this month
It’s almost here, folks. pic.twitter.com/IdL4atsucQ

Additionally, due to the delays, Tesla explored “a variety of designs” for the Roadster, potentially planning to abandon the design it showed off for the first time in 2017 and adopting an entirely new aesthetic.
-
According to The Information, Tesla considered utilizing a repurposed Model S Plaid and even wanted to upgrade the look to something like a Lamborghini Countach.
We’ve heard all of these things before, including teases about the date and how “soon” the Roadster will finally be ready to be shown off to the world (for the second time). Musk said that the event would occur in April, then May, then Chief Designer Franz von Holzhausen continued to say it would be coming “soon.”
We do expect to see the Roadster by the end of the year, and now with this new report swirling, it appears it could be sooner rather than later.
The wait has been incredibly long, but there is likely a good reason for it. Tesla’s desire to make the Roadster the craziest vehicle on the road was non-negotiable, and it likely took a lot of time and resources to develop and perfect into something that was safe and suitable for a vehicle like this.

Tesla finally got its Nevada Robotaxi Permit but with a few catches hard to miss
Nevada granted Tesla’s robotaxi permit, but capped the fleet at just ten vehicles for now.
Tesla has received its robotaxi permit in Nevada, more than two months after regulators closed the public comment period on the company’s application. News of the approval surfaced Wednesday night when Tesla investor and longtime company watcher Sawyer Merritt posted a copy of the interim order, and the Nevada Transportation Authority’s own carrier registry now lists the permit, AVNC Permit 002 under Docket 26-05015, as active for Tesla Robotaxi, LLC.
Tesla asked Nevada in June for authority to run up to 5,000 vehicles in Clark County within a year, however the permit the NTA issued is initially capping Tesla at ten fully autonomous vehicles and confines them to a defined geofence along the Las Vegas Strip corridor. Any expansion of that operating area, or any increase to the fleet size, requires the NTA’s approval first.

The order also sets rules that look more restrictive than what Tesla runs in Austin. Rides are barred on roads with posted speed limits above 45 miles per hour, pickups are off limits within a quarter mile of Harry Reid International Airport without separate authorization, and every vehicle has to carry visible “Robotaxi” markings while notifying riders before each trip that no one is driving. The order also requires “appropriate human supervision”, language that suggests Nevada isn’t ready to let Tesla offer the rides without a safety monitor that it has run in parts of Austin since January. As with standard protocol with robotaxi services, Tesla must report any accident, system failure, or vehicle that becomes stranded on a Nevada road within five business days.
Tesla is entering a market Nevada already knows well. Zoox, the Amazon owned robotaxi company, has run its own autonomous vehicle permit in the state since last year, building up to roughly 100 vehicles and 350,000 rides along the Strip. That history likely explains why the NTA started Tesla at ten cars rather than the fleet size the company asked for. The agency has a template for scaling a permit up once a company proves out its safety record.
-
Tesla’s Nevada application first surfaced in June, when the company filed for the permit alongside plans for a maintenance hub in southwest Las Vegas. The company has said it won’t meaningfully scale its robotaxi fleet anywhere until FSD v15 ships, expected in late 2026 or early 2027, which makes the ten vehicle cap less of a constraint today than it might look on paper. For now, Tesla has the legal right to start Nevada rides. Whether it starts before FSD v15 arrives is a separate question the permit doesn’t answer.
