Tesla's battery acquisitions are paying off in spades, and giving rivals a lot of pain
There was a time, not too long ago, when Tesla skeptics questioned the company’s focus in designing and producing its own batteries with a dedicated partner like Panasonic and a facility like Gigafactory 1 in Nevada. Batteries, after all, are available off-the-shelf from companies like LG Chem, and it seemed pretty futile for Tesla to insist that it needs its own battery supply for its future business.
Fast forward to 2020, and Tesla’s extreme focus on battery development is paying off in spades. Over the years, Tesla has acquired multiple companies that have, in some way, enabled the company to accelerate or improve its products’ batteries. Included among these are Grohmann Automation, whose machines are the bread and butter in Gigafactory 1, Maxwell Technologies, and more recently, HIBAR systems.
At this point, Tesla’s batteries have pretty much become the gold standard for EVs, and the company appears to be well on its way towards releasing vehicles that have a range of 400 miles or more. The Plaid Model S and X will likely be the first of these, as well as the next-gen Roadster, which will have 620 miles of range. Even the reasonably-priced Cybertruck tops out at over 500 miles of range per charge. Massive battery developments are needed to achieve these, and Tesla seems to have done it, or at least is well on its way.
This does not appear to be true for other OEMs attempting to enter the electric vehicle market. As veteran companies unveiled their EVs, and as none have really managed to hold a candle to Tesla’s flagship Model S in terms of range, it is becoming evident that the electric car maker’s investments in batteries may have actually been the right strategy all along. Daimler, for one, seems to be feeling this inconvenient truth, with works council chief Michael Brecht explaining during a recent interview with Manager Magazin that Tesla’s battery-related acquisitions are actually having an effect on Germany’s EV efforts.
Daimler launched its first EV, the Mercedes-Benz EQC, in 2018, and it has not really lived up to the hype. Despite being dubbed at some point as a potential “Tesla Killer” due to its pedigree and excellent German build quality, the all-electric SUV has faced battery shortages and low sales. Registrations in Germany for the vehicle only show about 55 units sold to date despite all the ad campaigns dedicated to the SUV. Battery supply shortages have also forced Daimler to cut the annual production target of the EQC by 50% from 60,000 to just 30,000.
Quite interestingly, Brecht partly blames Tesla for some of the challenges facing the EQC today. Explaining his points to the publication, he argued that one of the reasons Daimler is struggling with battery demand is because Tesla bought Grohmann Engineering, which has valuable technology that could be used for battery-related developments and activities. Brecht also mentioned that Grohmann was actually hired by Mercedes-Benz to build up its own battery manufacturing capacity.
Brecht’s statements are notable since it is quite rare to see a veteran car manufacturer actually point the finger at Tesla to explain the dire condition of its own EV program. One can only hope that perhaps, the EQC would be a lesson that Daimler could learn from. After all, Daimler, among German automakers, would likely have no issues tapping into Tesla’s established technologies, batteries and powertrains alike, as the two companies have already worked together in the past. Elon Musk has stated that eventually, Tesla may be open to selling its batteries and powertrains with other OEMs. If this were to happen, it would be wise for Daimler to wait right in front of the line to avoid another EQC-sized flop.

Tesla Energy has introduced the Powerwall Lease in conjunction with Tesla Electric, making the service available in Texas. This new option delivers whole-home backup power using two Powerwall units for a net monthly cost of $35 after credits, accompanied by a low fixed electricity rate.
Under the lease terms, customers pay a one-time order fee of $100. The base lease payment for the two Powerwalls is approximately $122 per month during the first year, subject to a 3 percent annual escalator thereafter. Enrollment in a qualifying Tesla Electric Backup plan or Virtual Power Plant plan provides an $87 monthly credit.

This credit lowers the effective cost to roughly $35 per month plus applicable tax.
Installation of the standard system carries no additional charge. The package features Storm Watch for outage protection and allows complete management through a single Tesla application. The system supplies continuous whole-home backup capability.
The Powerwall system enables households to maintain electricity during severe storms that disrupt the utility grid. When outages occur, the batteries automatically provide seamless backup power to the home.

Tesla Storm Watch monitors weather forecasts and ensures the units are fully charged ahead of anticipated severe weather events so that power remains available throughout the disruption, keeping lights, refrigeration, and other essential systems operating without interruption.
Availability is restricted to select Texas locations where retail electric choice exists. Participants must lease exactly two Powerwall units and maintain continuous enrollment with Tesla Electric. Solar panels cannot be included under this particular lease arrangement.
The monthly credit activates automatically once the system is installed, receives permission to operate, and enrollment is confirmed. To retain the credit, customers are required to stay enrolled in Tesla Electric and fulfill all program conditions.
Nonstandard installations that involve electrical upgrades or special permitting may lead to extra expenses and might impact eligibility for the credit, so be sure to check with either your installer or Tesla to ensure you will still qualify.
Elon Musk continues to tease the unveiling event for the Tesla Roadster, a continuing trend that has grown into a bigger game of “When” for fans who have been waiting years for the car to finally enter production.
A video shared on X of the Joe Rogan Experience podcast that Musk appeared on last year, teasing the Roadster unveiling, was shared once again on the social media platform. The poster said the Roadster event will be “unforgettable.”
Musk agreed:
Yes

The timing is interesting because just yesterday, Musk said that we will be getting flying cars, and for years, Tesla has hinted that it could develop a SpaceX cold gas thruster package that would help the car float or fly for a short period of time.
It would be reasonable to assume Tesla’s major delays with this unveiling event are likely caused by the company’s need to break the rules and push the envelope on nearly everything. Last July, Lars Moravy, Tesla’s VP of Vehicle Engineering, said:
“Roadster is definitely in development. We did talk about it last Sunday night. We are gearing up for a super cool demo. It’s going to be mind blowing. We showed Elon some cool demos last week of the tech we’ve been working on and he got a little excited.”
The latest updates that Tesla has given us are that the Roadster is in design development, and it did have several potential dates for an unveiling event this year, including April. It was then pushed to August.
However, there are no clues as to when Tesla will be ready, and fans are certainly getting frustrated with the delays.
For what it is worth, Franz von Holzhausen told Jay Leno this week that the event would be “very soon.”
We sure hope.

Tesla’s driverless Cybercab just passed a big test with State Governor
Florida’s governor rode Tesla’s Cybercab at a closed test track and called the experience impressive.
Florida Governor Ron DeSantis rode in a Tesla Cybercab on a closed test track this week and came away impressed, posting on X that the vehicle “successfully navigated all hazards — a kid running into the street, a crash with police stopping traffic, a Model S cutting us off, etc.” He called the ride “impressive.”
The stop was part of a broader event Monday at SunTrax, a 775 acre state owned proving ground in Auburndale that Florida built specifically to test autonomous and connected vehicles before they reach public roads. Standing next to a gold Cybercab, DeSantis described the car in plain terms: “You go in there and you just sit. You have a screen. There’s no steering wheel, no pedals. Clearly these things could be very beneficial.”

DeSantis paired the praise with a caveat that has followed autonomous vehicles since the category existed. “You don’t want to be in an autonomous vehicle and it drives you into a ditch. That would not be good,” he said, framing safety validation as the gate before wider deployment.
SunTrax, the 2.25 mile oval which the state calls the only high speed autonomous vehicle test track in the Southeast, can simulate rain, pedestrian crossings, hills and crowded urban conditions at highway speeds, letting companies push a car past what an early public rollout would risk. Tesla, Waymo and Beep all use the facility, and Florida’s regulatory approach, among the most permissive for autonomous vehicles in the country, doesn’t require a human operator inside a fully autonomous car.
Tesla has reason to want the blessing of Florida and states beyond, as the Cybercab entered volume production at Gigafactory Texas this spring and has since self certified as SAE Level 4 under Texas law. Public road testing so far has kept a safety monitor in the passenger seat, and Florida is where Tesla has been expanding its existing Model Y based Robotaxi service instead, adding Miami in July and then Orlando and Tampa two weeks later. A closed track endorsement from a sitting governor doesn’t change any of that, but it does put Tesla’s newest hardware in front of a state that has already shown it will move fast on rules.
