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 CEO Elon Musk confirms time spent with DOGE will drop ‘significantly’
Musk said he will likely remain with DOGE until the end of President Trump’s term, but would scale back his work ‘significantly’ to focus on Tesla.

Tesla CEO Elon Musk confirmed today during the company’s Q1 2025 Earnings Call that his time allocation to the Department of Government Efficiency (DOGE) will drop “significantly,” as he will now turn more of his attention back to the automaker.
“I believe the right thing to do is to fight the waste and fraud and get the country back on track…I think it’s critical work,” Musk said on the call, before stating that his time allocation to DOGE would drop back considerably in May.
Musk said that just one or two days per week would be spent tending to government affairs. The remainder of his time will be dedicated to Tesla’s efforts, which, in the near term, include the launch of the Cybercab, a Robotaxi platform in Austin, and several affordable models that will be available in the first half of the year.

Musk clarified that he would likely remain on the DOGE team for the remainder of President Trump’s term, but he will be significantly less focused on the government, and more attention will be spent toward Tesla.
It’s a big sigh of relief for Tesla investors and analysts, as many, including Wedbush’s Dan Ives, said that a move needed to be made or the company could continue to feel the significant ramifications of Musk’s lack of attention.

LIVE BLOG: Tesla (TSLA) Q1 2025 Company Update and earnings call
The following are live updates from Tesla’s Q1 2025 earnings call.

Tesla’s (NASDAQ:TSLA) Q1 2025 earnings call comes on the heels of the company’s Q1 2025 Update, which was released after the closing bell on April 22, 2025.
Tesla’s Q1 2025 Results:
- Total Revenues: $19.3 billion
- Total automotive revenues: $13.967 billion
- Total GAAP gross margin: 16.3%
- Gross Profit: $3.15 billion

The following are live updates from Tesla’s Q1 2025 earnings call. I will be updating this article in real time, so please keep refreshing the page to view the latest updates on this story.
16:20 CT – Hello, and happy earnings day to everyone! While Tesla missed the Street’s expectations, the stock has not shown its typical volatility at all. That being said, this earnings call is quite interesting due to the upcoming “Company Update.”
Tesla also reiterated its section about new vehicles that “remain on track for start of production in the first half of 2025” in its Update Letter. What are these vehicles? Just variants of the Model 3 or Model Y? Was the Cybertruck LR RWD one of them already? Or are they actually new cars that we’ve just never seen before?
Either 10, ten minutes and counting.
16:27 CT – Now I’m just curious if the Company Update will be a video. The thumbnail Tesla is using on X and YouTube shows an “Audio Webcast Only” graphic though. Three minutes and counting.
16:28 CT – And there’s the music. Wonder if it’s going to be on time.
16:34 CT – Annd we’re now on the Elon time threshold. Tesla stock is actually up 4% in after-hours today. Pretty nutty considering that the Q1 earnings are a miss.
16:36 CT – The earnings call is formally starting. Here we go.
Elon Musk takes the stage. “There’s never dull moment these days,” he said. He admits to the blowback from his work with DOGE. He also admitted that those against DOGE are bound to attack him and his companies, such as Tesla. Musk reiterates his belief that it’s important to fight waste and fraud. “I think it’s critical work,” Musk said.
16:40 CT – Musk discusses the protests against Tesla. He alleges that the protests are not organic. “The actual reason for the protests is that those who are receiving the waste and fraud want to continue receiving the waste and fraud,” he said.
Musk notes that starting next month, in May, his time allocation for DOGE will drop significantly. He will continue to spend a day or two on government matters or as long as the U.S. President wishes him to. “Starting next month, I will be allocating more of my time with Tesla,” Musk stated.
16:43 CT – Musk noted that Tesla is no stranger to challenges, but Tesla has been through the ringer several times in the past. “We’re not on the ragged edge of death….not even close,” he said.
He also highlighted that Tesla is on the cusp of autonomous cars and autonomous humanoid robots. Musk expects unexpected bumps this year, but he remains confident on the future of Tesla. The idea of Tesla potentially being the most valuable company in the world by far was reiterated. “Maybe as valuable than the next five companies combined,” he said.
“We expect to be selling fully autonomous rides in June in August,” Musk stated. He also stated that autonomy in cars will affect the bottom line by mid-2026.
16:47 CT – Musk discusses Tesla’s supply chain, highlighting that Tesla is the least affected automaker by the Trump tariffs. That being said, Tesla has been working to localize its supply chains for years. He admitted that tariffs are tough on companies where the margins are so low. Musk also clarified that he continues to advocate for lower tariffs, but that’s all he can do. Trump has the decision.
“The tariff decision is entirely up to the President of the United States. I will weigh in on the decision, but its primarily up to the President. I continue to advocate for lower tariffs rather than higher tariffs,” Musk said.
16:50 CT – Musk noted that he would now explain why he is very excited for Tesla’s future. He noted that Tesla is laser-focused on bringing autonomy in June in Austin, Texas. He highlights Tesla’s general approach to autonomy.
“We have a general solution (to autonomy) rather than a specific solution,” Musk said.
He also noted that Tesla expects to use thousands of Optimus robots in its factories this year. He expects Optimus’ ramp would be one of the fastest. By 2030, or 2029, a million Optimus per year is plausible.
16:52 CT – Musk highlighted that the Tesla Energy unit is doing very well. “We expect the stationary energy storage to scale to terawatts per year,” he said.

Tesla (TSLA) releases first quarter 2025 earnings results
Tesla’s quarter-end cash, cash equivalents and investments stand at a healthy $37 billion.

Tesla’s Q1 2025 earnings were released in an Update Letter, which was posted on the company’s Investor Relations website after markets closed today, April 22, 2025.
Tesla Q1 2025 Deliveries
Tesla’s first quarter vehicle deliveries fell short of expectations, with the EV maker delivering a total of 336,681 vehicles, comprised of 323,800 Model 3/Y and 12,881 other models, worldwide. Vehicle production was at 362,615 units in the first quarter, comprised of 345,454 Model 3/Y and 17,161 other models.
Tesla Energy continued its momentum in Q1 2025, with the division deploying 10.4 GWh of energy storage products during the quarter.
What Wall Street Expects
As noted in a Forbes report, expectations are high that Tesla will report a gain of $0.35 per share on $21.85 billion in revenue, though whisper numbers suggest that the company will only post a gain of $0.31 per share. Analysts polled by FactSet expect Tesla to see an EPS of $0.41 per share on revenues of $21.27 billion, as noted in an Investors’ Business Daily report.
Tesla’s Q1 2025 Results In a Nutshell
Following are highlights of Tesla’s Q1 2025 update Letter:
- Total Revenues: $19.3 billion
- Total automotive revenues: $13.967 billion
- Total GAAP gross margin: 16.3%
- Gross Profit: $3.15 billion
- EPS non-GAAP: $0.27 per share
- Free cash flow: $664 million
Key Updates:
Tesla’s total revenue decreased 9% YoY to $19.3 billion YoY. This was due to a decline in vehicle deliveries, in part due to the new Model Y changeover and reduced vehicle average selling price (ASP), among other factors.
Tesla is still profitable, though operating income decreased 66% YoY to $0.4 billion. This also resulted in a a 2.1% operating margin. Tesla’s profitability in the first quarter was affected by reduced vehicle ASP, a decline in vehicle deliveries, and an increase in operating expenses driven by AI and other R&D projects partially offset by a decrease in SG&A, among other factors.
Tesla’s quarter-end cash, cash equivalents and investments stand at a healthy $37 billion. The sequential increase of $0.4 billion was primarily the result of positive free cash flow of $0.7 billion.
