Why are Tesla Superchargers Only for Long-distance Travel?
Liquid-cooled Tesla Supercharger in Mountain View, CA
Before going on vacation around July 4th holiday, PlugInsights sent a short survey to me with questions about Tesla supercharging procedures and also about recent comments by Elon Musk. About half way into the short survey, it delves into Elon Musk’s supercharging “overuse” comment regarding some daily Tesla commuters relying on the free charging stations in southern California.
My first thought, this again. Musk’s comments made some waves last month but why dredge this issue to the surface in the form of a survey from PlugInsights, a division of RECARGO.
Is something afoot at Tesla? Why is the company worried enough to conduct a survey about this topic and especially Musk’s comments at the annual shareholders meeting. One question from the survey actually discusses the actual comments by Musk. “Before today, were you aware that Mr. Musk recently made these statements?”
Below are Musk’s comments at the recent annual shareholders meeting held in June:
(paraphrased via the survey)…”that superchargers are meant for free, long-distance travel” and “that drivers who aggressively use the network for local charging may receive an email reminder that it’s ‘cool to do this occasionally but it’s meant for a long-distance thing.’
So why did Elon Musk comment on this relatively small issue? Ashley Vance recent biography on Elon Musk points out that Musk usually doesn’t get involved in PR, unless an issue threatens one of his companies. So how could this threaten Tesla Motors? My speculation is the very real possibility of battery capacity loss and drastically reduced range with multiple instances of DC fast-charging on a daily basis.
Could these patterns lead to drastically reduced battery packs ranges by year three or four of ownership and possibly lead to Tesla replacing a lot of battery packs, due to their warranty coverage?
My speculation centers around 120 kW of DC energy flowing into the battery pack on a daily basis. Did Tesla test battery packs for multiple, daily DC-charging usage? Maybe not.
Musk mentioned at the annual shareholder meeting that fast charging was intended for destination traveling and implied it wasn’t for daily use by commuters.

The Idaho National laboratory conducted a study on DC fast-charging and its effects on battery packs some years ago and released findings in 2014. Using 2012 Nissan Leafs, the study compared the effects of different types of charging: level 2 charging (3.3 kW) and DC fast-charging (50 kW).
The study revealed after 40,000 miles of testing that there was little loss of initial capacity and that the DC-fast charging battery pack had only lost 3 percent more than the other Nissan Leaf using level 2 battery charging.

However, Tesla Superchargers are dishing out 120 kW DC versus the Idaho study of 50 kW, more than 2x the amount of electricity coming into battery pack. That’s a lot stress on the battery management system to keep heat levels down, plus these car owners are supercharging daily, maybe doing it twice a day?
Many automakers have said that DC fast charging is fine on the battery pack, as long as it’s not done excessively. It seems twice a day could be considered excessive and cause concern for Tesla execs. This could be leading up to some proviso with excessive supercharging and the battery pack warranty, hence the PlugInsights survey on usage and expectations.
What about you, any other thoughts on why this is such an issue for Tesla?
** My other mild theory is Tesla’s rising electricity costs for owners employing supercharging only mode. The results of PlughInsights survey showed that 26% of Model S owners polled have used Tesla Superchargers as a free local alternative to home charging.

On Friday, Tesla launched the Outlet Adapter that enabled Vehicle-to-Load (V2L) energy transfer, meaning owners could essentially utilize their cars as a power source for things like laptops, electric grills, or string lights.
However, even owners of some of the newest builds of the Model Y are finding out that their cars are not compatible with the new $80 accessory, stirring up a new complaint among members of the community.
Tesla launches V2L Outlet Adapter for Premium Model Y in the U.S.
Upon the release of the Outlet Adapter on Friday, I signed into my Tesla account to order the accessory. However, I was met with the dreaded “This product is not compatible with your 2026 Model Y” message at the bottom of the screen.
Some said their accounts also displayed the same message, but they ordered anyway. However, they might be surprised to find that this is no mistake; some of the newest Model Ys do not have the appropriate Power Conversion System (PCS). Mine, which was ordered on this day last year and delivered on August 31, has the old 48A, single-phase PCS.
Vehicles with the new, two-piece PCS are able to utilize V2L features on their cars:
🚨 Looks like you can hit the Parts Catalog and enter your VIN and check to see if your Model Y will be able to use the adapter for V2L.https://t.co/QA9zRk7n2k
h/t to @SawyerMerritt for finding this out.

Obviously, it’s disappointing. Many owners have taken delivery this year and still can not utilize the Outlet Adapter because their cars feature the old PCS:

It looks like if you have one of these older PCS units, you can upgrade, but the parts alone are $1,750, and that’s before Tesla adds labor for installing. It is honestly more logical to get some kind of portable power supply or power station at that point.

It is great that Tesla has enabled V2L for Model Y vehicles, but it is also unfortunate that vehicles that are less than one year old are not able to take advantage of this awesome new feature.
With that being said, it truly is a first-world problem; can you really complain when Full Self-Driving is available, maintenance is incredibly inexpensive, and the car has been so good through a year of ownership?
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

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.
