Tesla improves access to third-party charging stations
Tesla
Tesla has made significant strides in improving access to fast chargers around the world. This is an important development, not only for the company but for the future of sustainable transportation. Tesla aims to make charging an EV as convenient and practical as driving an internal combustion vehicle.
Tesla continues to improve the charging experience in a variety of ways. In addition to continually expanding its own Supercharger network, Tesla is also partnering with companies like EVgo in the U.S. to install Tesla connectors at their charging stations. Tesla has also recently opened up access to its own charging connector and charge port, allowing other companies to use Tesla's tech free of charge.
Tesla opening up its charging connector is a generous move but also a clever, strategic play. There is no doubt that electric vehicles are here to stay. The question is, what will the nozzle be on the gas pump of the future? With more private companies getting into the EV charging game, this move makes it easy for them to add the Tesla connector to their equipment. Tesla has already been in discussions with some of those companies. Tesla states, "network operators already have plans in motion to incorporate NACS at their chargers, so Tesla owners can look forward to charging at other networks without adapters."
Part of the Tesla experience is having access to its vast charging infrastructure that is as reliable as it is fast. Unfortunately, not all fast chargers are as reliable, which has prevented Tesla from displaying other charging options in their vehicles.
However, Tesla will now display select third-party charging stations that meet Tesla's performance and reliability standards.
Tesla will first roll out this update across Europe and Israel, allowing Tesla owners to find third-party charging stations directly in the vehicle's navigation system. This will not only allow users to easily find and navigate to compatible chargers but also allow the vehicle to preheat its battery to maximize charging speed.
Charger Criteria
For a charging station to be added as a 'Qualified Third-Party Charger' and appear in Tesla's navigation system, it must meet these conditions over a 60-day period:
At least one compatible charging connector
Frequently used by Tesla drivers at least once every four days
Average charge success rate is 90% or higher
Stations will be removed from Tesla’s navigation system if any of the following conditions are met over a 14-day period:
No charge sessions detected
Average charge success rate falls below 70%
Tesla's efforts to improve access to third-party fast charging will make it easier and more convenient for Tesla owners to charge their EVs, ensuring a smooth charging experience. By expanding its network of charging stations and making it easier for drivers to access and pay for charging, the company is making it more practical for drivers to own and use their electric vehicles.
Expect this improvement to Tesla's navigation system to expand to additional regions in the future as Tesla tests and evaluates its software and additional charging stations.
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 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.
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.
