Tesla Opens Superchargers in the U.S. to Other EVs: Price and Membership

Tesla officially opens up select Superchargers in the U.S. to all EVs

Not a Tesla App

Tesla has officially opened up select Superchargers in the U.S. to all compatible electric vehicles. This comes on the heels of news that Tesla has been retrofitting various Superchargers with its Magic Dock solution that allows Tesla to easily support the standard CCS connector in addition to Tesla's own NACS connector.

Europe

Tesla has previously opened up Superchargers in several countries around the world, although that was significantly easier for Tesla since Tesla uses the standard CCS connector in most countries outside the U.S. and Canada. In the U.S. Tesla needed to retrofit Superchargers with provide a solution that would support multiple connectors.

Magic Dock

Tesla needed to develop a solution to be able to continue to support their own NACS connector in addition to the CCS connector. The Magic Dock does that in an elegant and simple way. The Magic Dock houses a CCS adapter inside that locks onto the Tesla plug only when needed. Tesla owners will be able to continue charging at these stations without any changes.

Cost for Non-Teslas

Non-Tesla vehicles charging at Superchargers will pay a slight premium over their Tesla counterparts. An early look at Superchargers that Tesla has opened up reveals that Tesla is charging about $0.10 more per kWh to charge other EVs. This is about a 25% premium over Tesla's standard rate, although Supercharger prices vary by station and time of day.

Membership

Tesla is also offering a monthly membership option for non-Tesla owners who wish to reduce their price per kilowatt hour. For $12.99/month, non-Tesla owners can subscribe to lower their charging rate to be the same as Tesla vehicles.

There are currently no other benefits to the membership and non-Tesla owners are limited to the same Superchargers whether they have a membership or not.

The membership is only open to non-Teslas and will not lower the charging rates for Tesla owners, although that could be an interesting option if Tesla decides to consider it.

Idle fees

Tesla charges idle fees for vehicles that stay in a Supercharging spot after their vehicle has finished charging. The idle fees vary depending on how full the station is and they're waived if the station is at less than 50% capacity.

Tesla is charging the same idle fees for Teslas and non-Tesla vehicles.

Compatible EVs

If your EV uses CCS, or you have an adapter for your vehicle that can connect to a CCS1 connector then you'll likely be able to use Tesla's Superchargers. The only other physical requirement is that your vehicle's charge port has to reach Tesla's Supercharger cable without blocking access to others.

Congestion

While Tesla owners are right to be concerned about issues such as Supercharger congestion and dock blocking, Tesla is doing everything it can to minimize these issues.

Tesla has no plans to open up all of its Superchargers. Tesla told the U.S. government that it was going to open up 7,500 Supercharger stations to all compatible electric vehicles. This number includes current and future Superchargers.

The most popular Tesla Superchargers will likely remain exclusive to Tesla vehicles as Tesla doesn't want to make congestion worse at its most used locations.

However, non-Tesla vehicles will bring additional traffic to smaller Superchargers that are solemnly used, resulting in additional profit for Tesla, which will allow them to further expand their Supercharger network.

In fact, without Tesla opening up Superchargers to other EVs, some Supercharger locations may not be possible. When Tesla decides to open a new charging location one of the things they're looking for is the number of vehicles that will take advantage of the Supercharger and how long it will take Tesla to recoup the cost of opening the location.

Dock Blocking

Dock blocking is going to be a new term that we're unfortunately going to hear and experience more often. The term refers to vehicles in Supercharger locations taking up more than one spot and blocking access to other vehicles.  Tesla's Superchargers feature very short cables to reduce damage and risk. This works well for Teslas since their charging ports are all located in the same location.

However, not all EVs have a charge port that can easily reach the end of a Supercharger cable. Depending on the vehicle, this could lead to a vehicle taking up two spots, or going over the line to be able to reach the Supercharger's cable.

Stations Opened

Tesla appears to have opened up about eight stations across the U.S. yesterday. These stations are in various parts of New York and California but expect Tesla to open more stations soon.

In typical Tesla fashion, Tesla rolls out changes slowly as it gathers feedback. If Superchargers are working as expected Tesla will slowly open up more Superchargers as it retrofits old locations with its Magic Dock.

Although many Tesla owners may be worried about a worse experience at Superchargers, this is a big win for not only Tesla but for sustainable transportation. Tesla provides some of the faster and most reliable charging stations in the world and this change will help convince more vehicle buyers into choosing an EV.

Tesla LFP Batteries Can Now Be Warmed up While Supercharging Using Innovative Feature

Not a Tesla App

Tesla’s been on a roll with Supercharger improvements lately, from the 325kW charging update for the Cybertruck, to 500kW with V4 Superchargers coming next year. While those improvements have been limited to the Cybertruck, Tesla didn’t put all their focus on their new flagship vehicle, but looked at their more affordable vehicles as well.

LFP Battery Heating

Tesla’s Superchargers can now heat LFP Batteries - those that are in the Model 3 and Model Y Rear Wheel Drive variants. This applies to Long Range and Standard Range models, which saw a limited run. This is another update included as part of the 2024 Tesla Holiday Update - which really arrived with a lot of unannounced new features and capabilities.

The change is pretty interesting - Superchargers of the V3 and V4 variety can now pre-heat batteries for Model 3 and Model Y vehicles equipped with LFP battery packs. That means those vehicles are able to get back on the road faster when it's extremely cold. Of course, Tesla still advises you to precondition before you arrive, saving drivers time and money.

Max de Zegher, Tesla’s Director of Charging, also commented on the new feature. Essentially, Tesla is inducing an AC (alternating) ripple current through the battery to warm it up. Keep in mind that Superchargers are DC charging. That means it is possible to get a cold-soaked LFP vehicle on the road 4x faster than before, assuming that it didn’t precondition at all and that it is in the worst-case scenario (below 0ºF).

In essence, Tesla is using some engineering magic to turn the circuits inside the LFP battery into an electric heater - and powering that heater through the Supercharger. An AC ripple current is a small oscillation in the DC charging current that generates heat through electrical resistance, warming up the battery. Those ripples are a byproduct of converting AC to DC and back - so Tesla is using the onboard charger to induce those ripples to warm up the battery. Definitely an innovative technique that’s really only possible with the versatility of the NACS connector.

We’re hoping Tesla can implement this across their full lineup of vehicles, but we’ll have to wait and see how it is trialed across LFP vehicles first and if it is even possible on vehicles with 2170 or 4680 battery packs.

Tesla Included FSD V12.6.1 and V13.2.4 in the Same Update: What Caused This and What It Means

Not a Tesla App

Tesla launched two FSD updates simultaneously on Saturday night, and what’s most interesting is that they arrived on the same software version. We’ll dig into that a little later, but for now, there’s good news for everyone. For Hardware 3 owners, FSD V12.6.1 is launching to all vehicles, including the Model 3 and Model Y. For AI4 owners, FSD V13.2.4 is launching, starting with the Cybertruck.

FSD V13.2.4

A new V13 build is now rolling out to the Cybertruck and is expected to arrive for the rest of the AI4 fleet soon. However, this build seems to be focused on bug fixes. There are no changes to the release notes for the Cybertruck with this release, and it’s unlikely to feature any changes when it arrives on other vehicles.

While this update focuses on bug fixes, Tesla’s already working on bigger features for FSD V13.3, which we have already confirmed to include improvements to highway following and speed control.

FSD V12.6.1

FSD V12.6.1 builds upon V12.6, which is the latest FSD version for HW3 vehicles. While FSD V12.6 was only released for the redesigned Model S and Model X with HW3, FSD V12.6.1 is adding support for the Model 3 and Model Y.

While this is only a bug-fix release for users coming from FSD V12.6, it includes massive improvements for anyone coming from an older FSD version. Two of the biggest changes are the new end-to-end highway stack that now utilizes FSD V12 for highway driving and a redesigned controller that allows FSD to drive “V13” smooth.

It also adds speed profiles, earlier lane changes, and more. You can read our in-depth look at all the changes in FSD V12.6.

Same Update, Multiple FSD Builds

What’s interesting about this software version is that it “includes" two FSD updates, V12.6.1 for HW3 and V13.2.4 for HW4 vehicles. While this is interesting, it’s less special when you understand what’s happening under the hood.

The vehicle’s firmware and Autopilot firmware are actually completely separate. While a vehicle downloading a firmware update may look like a singular process, it’s actually performing several functions during this period. First, it downloads the vehicle’s firmware. Upon unpacking the update, it’s instructed which Autopilot/FSD firmware should be downloaded.

While the FSD firmware is separate, the vehicle can’t download any FSD update. The FSD version is hard-coded in the vehicle’s firmware that was just downloaded. This helps Tesla keep the infotainment and Autopilot firmware tightly coupled, leading to fewer issues.

What we’re seeing here is that HW3 vehicles are being told to download one FSD version, while HW4 vehicles are being told to download a different version.

While this is the first time Tesla has had two FSD versions tied to the same vehicle software version, the process hasn’t actually changed, and what we’re seeing won’t lead to faster FSD updates or the ability to download FSD separately. What we’re seeing is the direct result of the divergence of HW3 and HW4.

While HW3/4 remained basically on the same FSD version until recently, it is now necessary to deploy different versions for the two platforms. We expect this to be the norm going forward, where HW3 will be on a much different version of FSD than HW4. While each update may not include two different FSD versions going forward, we may see it occasionally, depending on which features Autopilot is dependent on.

Thanks to Greentheonly for helping us understand what happened with this release and for the insight into Tesla’s processes.
