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 lands regulatory green light for Robotaxi testing in new state
This will be the third state in total where Tesla is operating Robotaxi, following Austin and California.
Tesla has landed a regulatory green light to test its Robotaxi platform in a new state, less than three months after the ride-hailing service launched in Texas.
Tesla first launched its driverless Robotaxi suite in Austin, Texas, back on June 22. Initially offering rides to a small group of people, Tesla kept things limited, but this was not to be the mentality for very long.
It continued to expand the rider population, the service area, and the vehicle fleet in Austin.
The company also launched rides in the Bay Area, but it does use a person in the driver’s seat to maintain safety. In Austin, the “Safety Monitor” is present in the passenger’s seat during local rides, and in the driver’s seat for routes that involve highway driving.
Tesla is currently testing the Robotaxi platform in other states. We reported that it was testing in Tempe, Arizona, as validation vehicles are traveling around the city in preparation for Robotaxi.

Tesla is also hoping to launch in Florida and New York, as job postings have shown the company’s intention to operate there.
However, it appears it will launch in Nevada before those states, as the company submitted its application to obtain a Testing Registry certification on September 3. It was processed by the state’s Department of Motor Vehicles Office of Business Licensing on September 10.

It will then need to self-certify for operations, essentially meaning they will need to comply with various state requirements.
This will be the third state in total where Tesla is operating Robotaxi, following Austin and California.
CEO Elon Musk has stated that he believes Robotaxi will be available to at least half of the U.S. population by the end of the year. Geographically, Tesla will need to make incredible strides over the final four months of the year to achieve this.
Tesla is set to improve a critical feature that has not been present in older vehicles with a new update.
Tesla vehicles feature a comprehensive suite of driver assistance features, some of which aid in driving itself, while others support the vehicle’s surroundings.
One of those features is that of Driver Visualization, and with the rollout of a new update, owners of Intel-based Tesla vehicles are receiving an upgrade that will come with a simple software update.
Tesla plans to use Unreal Engine for driver visualization with crazy upgrade
The update will provide new visualizations while Intel-based vehicles are in reverse, a feature that was not previously available, but will be with Software Update 2025.32.2.
The improvement was spotted by Not a Tesla App via TheBeatYT_evil:
Noticed something new in 2025.32.2 on my Intel MCU + USS car with FSD.
When shifting into reverse, the full FSD visualization now stays on instead of switching to the old plain autopilot visuals.

Previously, vehicles Tesla built were equipped with Intel-based processors, but newer cars feature the AMD chip, which is capable of rendering these visualizations as they happen. They were capable of visualizations when driving forward, but not in reverse, which is what this change resolves.
It is a good sign for those with Intel-based vehicles, as Tesla seems to be paying attention to what those cars are not capable of and improving them.
This was an undocumented improvement associated with this particular update, so you will not find any mention of it in the release notes that Tesla distributes with each update.

Tesla looks to make a big splash with Robotaxi in a new market
Tesla has been transparent that it is prioritizing safety, but it believes it can expand to basically any geographical location within the United States and find success with its Robotaxi suite. CEO Elon Musk said it could be available to half of the U.S. population by the end of the year.
Tesla is looking to make a big splash with Robotaxi in a new market, as the company was spotted testing validation vehicles in one region where it has not yet launched its ride-hailing service.
After launching Robotaxi in Austin in late June, Tesla followed up with a relatively quick expansion to the Bay Area of California. Both service areas are operating with a geofence that is expansive: In Texas, it is 173 square miles, while in the Bay Area, it is roughly 400 square miles.
Tesla has been transparent that it is prioritizing safety, but it believes it can expand to basically any geographical location within the United States and find success with its Robotaxi suite. CEO Elon Musk said it could be available to half of the U.S. population by the end of the year.
There have been plenty of reports out there that have speculated as to where Tesla would land next to test Robotaxi, and Nevada, Florida, Arizona, and New York have all been in the realm of possibility. These regions will need to approve Tesla for regulatory purposes before Robotaxi can officially operate.
Tesla is still testing and performing validation in several regions, and in Tempe, Arizona, things are moving forward as a Model Y with a LiDAR rig was spotted performing ground truth for the platform:

With the LiDAR unit, many followers of the self-driving and autonomy space might wonder why Tesla uses these apparatuses during validation, especially considering the company’s stance and vision-based approach.
LiDAR is used for “ground truth,” which is basically a solidification or confirmation of what the cameras on the car are seeing. It is a great way to essentially confirm the accuracy of the vision-based suite, and will not be used on Robotaxi units used within the ride-hailing suite.
The Robotaxi platform was made available to the public earlier this month, as Tesla launched its app for iOS users.
