Are we going to get a standards war in the EV space? I doubt it, but things are heating up between Tesla and CharIN, the association leading the CCS standard.
It’s awkward because Tesla is also part of the association.
The automaker is challenging the J1772/CCS combo connector, which has been adopted by virtually all other automakers selling vehicles in North America, in the hope that its sleeker and more powerful design will win by force of sheer numbers.
Tesla dominates the EV market in America to such a degree that even though all other automakers currently selling EVs on the market are using the J1772/CCS connector, there are still more EVs in North America using the Tesla connector, now known as the North American Charging Standard (NACS).
The Supercharger network is also undoubtedly the best and most extensive DC fast-charging network in the market.
These are good points for Tesla and NACS, but the automaker still faces an uphill battle to get the connector actually adopted as a standard, and now CharIN is entering the battle.
CharIN, or Charging Interface Initiative, is “an association with nearly 300 international members dedicated to promoting interoperability based on the Combined Charging System (CCS) and the Megawatt Charging System (MCS) as the global standard for charging vehicles of all kinds.”
Tesla, which has adopted CCS in Europe, is a member of the association – that is why it was sort of a surprise that after 10 years of selling cars with its own proprietary connector in North America and recently announcing that it will let non-Tesla CCS EVs on its Supercharger network, Tesla decided to now open its connector as a standard.
CharIN has now issued a statement about Tesla’s move to open the connector, and the association is clearly not happy with its member:
In response to Tesla’s announcement on November 11, 2022, to publicly release the North American Charging Standard (NACS), the Charging Interface Initiative (CharIN e.V.) and its CharIN North America Chapter (operating as CharIN Inc.), would like to issue the following statement. CharIN is the largest global association focused on the electrification of all forms of transportation based on the seamless and interoperable charging experience enabled by the Combined Charging System (CCS) and the Megawatt Charging System (MCS). CCS and MCS are the global standards for charging vehicles of all kinds.
The association started out by congratulating Tesla for using DIN 70121 and ISO 15118-02 communication standards for the NACS and the company’s general contribution to electrification.
But it quickly scolds Tesla for moving away from CCS:
However, we encourage stakeholders to investigate ways to focus on market acceleration rather than the creation of yet another form factor alternative, which will lead to further consumer confusion and delay EV adoption. CCS has gone through many years of rigorous standardization processes, which is a required activity for any new standard proposal. After a decade of collaborative work, the domestic and international EV industry has aligned around CCS.
They added to the statement a list of reasons why the industry is backing CCS (I added some counterpoints in parentheses):
Nearly 300 domestic and international CharIN members are using or investing in CCS.
The majority of major domestic and international automakers are using and supporting CCS, including Audi, BMW, Daimler, Ford Motor Company, General Motors, Honda, Hyundai/Kia, Lucid, Lotus, Mazda, MAN, Mercedes-Benz, Navistar, New Flyer, Nikola, Nissan, PSA Groupe, Proterra, Renault, Rivian, Scania, Stellantis, Subaru, Suzuki, Tata Motors, Tesla, Toyota, Volvo, and Volkswagen.
In the US, CCS is used in over 50 passenger vehicle models. (Yes, but Tesla with NACS outsells all of them combined with 4 models.)
The Combined Charging System can connect to all AC charging stations without an adapter via the J1772 standard (NACS has the same connector for AC and DC).
Worldwide, there are 61,000 DC fast chargers using the CCS connector, compared to 40,000 Tesla Super chargers according to data published by CharIN and Tesla. (That includes both CCS 1 and CCS 2, which are different connectors, nor should it be relevant anyway because vehicles rarely move continents.)
In North America (including the US and Canada), there are 18,880 CCS connectors compared to 18,405 Tesla Super charger connectors and 178,926 J1172 connectors compared to 15,529 Tesla destination connectors, according to recent Plugshare data (includes public and restricted use). (The fact that Tesla almost has deployed as many Superchargers as all other charging networks combined is kind of crazy actually. Also, I’d note that power-wise Tesla is probably higher since many of those CCS stations are capped at 50 kW, and also many of those stations are located at car dealers, which are ideal locations for DC fast-charging.)
CharIN also suggests in its response to Tesla’s NACS that it will have difficulties passing the standard through standard bodies:
At a minimum, the Tesla proposal will have the hurdle of passing through an established standardization process via standards bodies, such as ISO, IEC, and/or SAE.
The association basically ends its statement by asking Tesla to come back into the fold with CharIN and CCS.
Electrek’s Take
I have doubts about Tesla really thinking that it can make it happen at this point. I think Tesla only wants a few automakers to adopt the standard, and Aptera already did, and that will fulfill the requirement for the federal charging infrastructure funding.
If Tesla had tried to do this five years ago and stuck to it until now, it might have worked, but not now.
Even though Tesla still dominates the EV market in North America by a wide margin, and therefore the NACS connector dominates, there are now too many major EV programs for other automakers using CCS in the works to make a change in my opinion.
But again, I think Tesla knows that.

Capable of delivering up to 1,200 kW of power to get electric commercial trucks back on the road in minutes, the new ABB MCS1200 Megawatt Charging System is part of an ecosystem of electric vehicle supply equipment (EVSE) that ABB’s bringing to this year’s ACT Expo.
ABB E-mobility is using the annual clean trucking conference to showcase the expansion of its EVSE portfolio with three all-new charger families: the field-upgradable A200/300 All-in-One chargers, the MCS1200 Megawatt Charging System for heavy-duty vehicles shown (above), and the ChargeDock Dispenser for flexible depot charging.
The company said its new product platform was built by applying a computer system-style domain separation to charger design, fundamentally improving subsystem development and creating a clear path forward for site and system expansion. In other words, ABB is selling a system with both future-proofing and enhanced dependability baked in.
“We have built a system by logically separating a charger into four distinct subsystems … each functioning as an independent subsystem,” explains Michael Halbherr, CEO of ABB E-mobility. “Unlike conventional chargers, where a user interface failure can disable the entire system, our architecture ensures charging continues even if the screen or payment system encounters issues. Moreover, we can improve each subsystem at its own pace without having to change the entire system.”

The parts of ABB’s new EVSE portfolio that have been made public so far have already been recognized for design excellence, with the A400 winning the iF Gold Award and both the A400 and C50 receiving Red Dot Design Awards.
New ABB chargers seem pretty, good

ABB says the systemic separation of its EVSE enhances both reliability and quality, while making deployed chargers easier to diagnose and repair, in less time. Each of the chargers’ subsystems can be tested, diagnosed, and replaced independently, allowing for quick on-site repairs and update cycles tailored to the speed of each systems’ innovation. The result is 99% uptime and a more future-proof product.
“The EV charging landscape is evolving beyond point products for specific use cases,” continued Halbherr. “By implementing this modular approach with the majority of our R&D focused on modular platforms rather than one-off products … it reduces supply chain risks, while accelerating development cycles and enabling deeper collaboration with critical suppliers.”
Key markets ABB is chasing

PUBLIC CHARGING – with the award winning A400 being the optimal fit for high power charging from highway corridors to urban locations, the latest additions to the A-Series All-in-One chargers offer a field-upgradable architecture allowing operators to start with the A200 (200kW) with the option to upgrade to 300kW or 400kW as demand grows. This approach offers scalability and protects customer investment, leading to Total Cost of Ownership (TCO) savings over 10 years.
PUBLIC TRANSIT AND FLEET – the new Charge Dock Dispenser – in combination with the already in market available HVC 360 – simplifies depot charging with a versatile solution that supports pantograph-, roof-, and pedestal charging options with up to 360kW of shared power and 150m/490 ft installation flexibility between cabinet and dispensers. The dispenser maintains up to 500A output.
HEAVY TRUCKS – building the matching charging infrastructure for commercial vehicles and fleets represents a critical innovation frontier on our journey to electrify transportation. Following extensive collaboration with industry-leading truck OEMs, the MCS1200 Megawatt Charging System delivers up to 1,200kW of continuous power — 20% more energy transfer than 1MW systems — providing heavy-duty vehicles with purpose-built single-outlet design for the energy they need during mandatory driver breaks. To support other use cases, such as CCS truck charging, a dual CCS and MCS option will also be available.
ABB says that the result of its new approach are chargers that offer 99% plus uptime — a crucial statistic for commercial charging operations and a key factor to ensuring customer satisfaction. The new ABB E-mobility EVSE product family will be on display for the first time at the Advanced Clean Transportation Expo (ACT Expo) in Anaheim, California next week, then again at Power2Drive in Munich, Germany, from May 7-9.

Along with Tennessee Tech, Tennessee-based ultralight aircraft company Whisper Aero has secured a $500,000 grant to help advance the company’s innovative electric jet motor concept off the drawing board and onto the testing phase.
Earlier this month, the Tennessee Department of Economic and Community Development (TNECD) announced plans to award $500,000 to Tennessee Tech and Whisper Aero through the Transportation Network Growth Opportunity (TNGO) initiative.
“We look forward to using these award dollars to place students in internships working directly with Whisper Aero leaders,” said Tennessee Tech President Phil Oldham. “By learning from an electric propulsion innovator like Whisper Aero, our students will gain invaluable perspective and can take what they have learned in the classroom and apply it right here in Tennessee.”
The grant will see a Whisper Aero glider fitted with a pair of the company’s eQ250 electric-powered jet “propulsors” for UltraQuiet flight. Tennessee Tech faculty and students will carry out copper-bird ground testing to ensure the safe integration of engines, batteries, and controllers, and kickstart Tennessee Tech’s new Crossville Mobility Incubator.
Whisper Aero’s main claim to fame is its innovative UltraQuiet WhisperDrive (above). It’s effectively an electrically spun ducted fan jet engine that uses a large number of stiff composite fan blades inside a lightweight, acoustically treated duct. With so many blades, the Whisper Aero propulsor can push more air than a conventional prop while spinning much more slowly. As such, the “blade passage frequency” moves up to more than 16,000 Hz – outside the range of most human hearing but not, supposedly, high enough to freak out the beagles.
The Whisper Aero ultralight is effectively an Aériane Swift3 glider fitted with a pair of Whisper’s eQ250 propulsors, each capable of up to 80 lbs. of thrust. The Ultralight has a wingspan of over 40 ft with a maximum L/D of 35:1 and can be stressed to a design loading of +6/-4g, making it capable of some pretty impressive acrobatic feats.
The Swift3 glider is designed for a low speed, low power cruising speed of 45–55 knots with “just” 6.5 hp. Power-off glides from a few hundred feet showed a low sink rate, and a climb rate of 1,250 ft/min with full self-launching power (in other words: the Whisper glider doesn’t have to be towed by a launch vehicle, like a conventional ultralight glider).
Quiet cool
Dual WhisperDrive fans deliver ~160 lbf of thrust; via Whisper Aero.
Range under full power is about 109 miles with current battery tech, but it’s expected that range under the latest EPiC 2.0 energy batteries would rise to nearly 170 miles.
Nathan Millecam, CEO of Electric Power System, said, “EPiC 2.0’s leap in energy density and thermal performance has enabled a significant increase in range, a clear validation of our next-gen cell technology. We are impressed by what the Whisper team continues to achieve in advancing electric aviation.”
The press release concludes explaining that flight tests are expected to show that the Whisper Aero glider can be flown, “a few hundred feet away from neighborhoods without any disturbances, while carrying a 220 lbs. payload with full range,” which is all kind of ominous in today’s political climate, but still pretty neat from a purely tech perspective.
With support from TNECD’s Transportation Network Growth Opportunity (TNGO) initiative, Tennessee Tech University and Whisper Aero are partnering to advance next-generation propulsion technology in the aerospace industry. This collaboration will enhance aerospace research and workforce development, ensuring Tennessee remains a leader in cutting-edge mobility solutions.

A Tesla Cybertruck owner believed Elon Musk’s claims that the Cybertruck would be able to “act as a boat” and “cross rivers”, and he got his $100,000 stuck because of it.
Elon Musk has often made claims about how Tesla vehicles could float and briefly serve as a boat in the past.
We have never been taken too seriously because Tesla’s warranty states something different about taking the vehicle into water.
However, the CEO doubled down on the claim specifically for the Cybertruck.
Cybertruck will be waterproof enough to serve briefly as a boat, so it can cross rivers, lakes and even seas that aren’t too choppy.
The CEO added that the goal is for a Cybertruck to be able to cross the water between SpaceX’s Starbase and South Padre Island in Texas, which is about 360 meters (1,100 feet).
We have been taking the Cybertruck more seriously with water because we learned that Tesla built a ‘wade mode’ for the truck to be able to go into the water. Tesla says the mode increases the ride height to the max and temporarily “pressurizes the battery pack.”
The problem is that it is activated through the off-roading mode, which is not covered under Tesla’s warranty – so we are taking everything with a grain of salt.
Whenever Tesla’s warranty contradicts what Musk says, it is better to follow to the warranty.
A Tesla Cybertruck owner in Truckee, California, appears not to have received this sage advice since they activated the wade mode and attempted to get into the water.
The Cybertruck owner quickly got stuck. The local California Highway Patrol (CHP) shared some pictures of the aftermath (via Facebook):
CHP Truckee helped with the recovery and commented on the incident:
Cybertruck activated “Wade Mode”… and waded a bit too far… We’re all for testing boundaries… but maybe not the waterline. Remember folks, “Wade Mode” isn’t “Submarine Mode.” If your plans include exploring the great outdoors, make sure to know your limits and the terrain.
There’s no detail on the damage to the Cybertruck, if any.
At the risk of stating the obvious, this is clearly more of a user error than a Cybertruck problem.
I think the verdict is clear: Cybertruck is far from the best electric pickup truck for off-roading.
However, in general, you shouldn’t expect a truck to get out of water on a muddy bank.
I think a lot of Cybertruck owners are new to trucking and off-roading, and they are making the truck look worse than it is at off-roading.
If you want to take your Cybertruck off-road, I recommend to first go with an off-roading guide that can help avoid some simple mistakes like this.
Also, in general, don’t take Elon Musk’s claims at face value when he says that Tesla vehicles can do something that sounds like an exaggeration. It probably is an exaggeration.
