Study finds that using Superchargers frequently doesn't cause a significant difference on battery life
It has long been believed in the industry that frequent DC fast charging for your Tesla or any EV is terrible for battery longevity. However, a new report from Recurrent, which analyzed data from over 12,500 Tesla vehicles in the US, clearly shows little to no difference in battery degradation between frequent and rare fast charging.
Recurrent studied fast charging on thousands of Tesla vehicles in the US to learn if the software and safety mechanisms in the battery management system (BMS) prevent damage to the battery. With Labor Day travel coming up, this is the perfect time to share what is fact and fiction when it comes to fast charging.
The Recurrent Study: A Comprehensive Analysis
Your electric vehicle battery uses direct current (DC) power. However, the electricity from the grid (or from an outlet) is alternating current (AC). In-home charging, which is AC charging, the car’s onboard charger converts the AC electricity to DC and then sends it to the battery. The onboard charger has a built-in limit on how quickly it can do this. The maximum speed is usually around 11 kW, so AC charging can generally add 20-40 miles per hour, depending on the vehicle.
On the other hand, DC charging happens when the conversion to DC energy happens outside of the car. This is almost exclusively reserved for public charging stations and Tesla Superchargers. Since the electricity going into the car bypasses the onboard converter, it can refill the battery much faster. One of the biggest concerns with fast charging is that it can, theoretically, damage the battery by pushing too much energy into the battery too quickly. This would lead to irreparable, long-term range loss.
Key Findings: No Significant Impact on Battery Degradation
Will fast charging hurt my EV battery? The short answer is that occasional fast charging is fine. The study compared cars that fast charge at least 90% of the time to cars that fast charge less than 10% of the time. In other words, people who almost exclusively fast charge their car and people who rarely fast charge.
The results show no statistically significant difference in range degradation between Teslas that fast charge more than 90% of the time and those that fast charge less than 10% of the time.
Initial analysis by the team at Recurrent suggests that the study findings can be applied across Tesla models and other EV manufacturers. However, detailed research is being conducted on other popular vehicles Recurrent supports. In short, the robust thermal, voltage, and battery management systems that EV makers have invested in protect their batteries from damage with routine fast charger use.
Tesla specifically does an excellent job regulating power to and from the battery based on the temperature of the battery pack, its state of charge (charge percentage), and other environmental factors such as external temperature.
When Fast Charging Can Cause Damage
When is fast charging more likely to cause damage? There are several times when fast charging may impact your EV battery more. Avoid fast charging in extreme heat without preconditioning your battery. Preconditioning is when the car’s thermal management system pre-cools or heats the battery to accept a higher charge rate.
Typically, the battery will be preconditioned if you set your car’s navigation to a fast charge station. Similarly, precondition the battery before fast charging in extreme cold. Driving a bit before fast charging is often enough to warm up the battery or get to the fast charger using your car’s navigation. Avoid fast charging your EV at very low states or very high states of charge since battery resistance will be higher.
Overall, this study adds to the growing body of knowledge regarding EV battery longevity and charging practices. Nonetheless, being mindful of battery health during extreme temperatures is still encouraged.

Tesla has added a new menu to its app that organizes various settings
Today, Tesla has updated its app to introduce a new menu that reorganizes vehicle, home energy, and account settings in a more logical and more discoverable manner.
Tesla updated its app to version 4.30 back on February 15th for iOS and followed suit with an Android update shortly thereafter. The app update included some significant changes such as a new Home Energy demo, Wall Connector charging charts, and a better view of your last Supercharger session.
However, the addition of the new menu arrived today thanks to under-the-hood changes Tesla had already made.
The changes in the latest Tesla app don't require an app update
The main change in the app is the new menu which replaces the user's profile picture.
Since this area was already used to change Tesla account and app settings and Tesla product preferences, the menu icon is more intuitive than an avatar.
However, after tapping into the menu, the user is greeted with a completely reorganized section. Instead of featuring horizontally scrolling tiles for different products and features, which was getting fairly long, Tesla has consolidated the features and now presents them vertically.
In the new profile section, Tesla has grouped lumped in account information and app settings. This includes personal information, order history as well as app settings, including calendar sync and app notifications.
Charging is now a top-level feature instead of being buried in the Account section. This section highlights your most recent Supercharger charging session which was redesigned during the 4.30 app update. It also lets you manage your payment method and view your Supercharger history.
My Products is the new way to add or remove Tesla products from your account. It now nicely displays all of your existing Tesla products and lets you dig into each one. By diving into each product, you're able to give access to another user, remove the product from your Tesla account if applicable, rename the product, or jump into the product view.
Vehicle and Home Screens
If you have a Tesla vehicle and a Home product, such as Solar or a Wall Connector, the way to switch between products is to swipe to the side. However, this wasn't very intuitive and Tesla has now added a dropdown next to the Home or Vehicle name that brings up a quick menu that lets you jump to other products.
If you already have app version 4.30, there's no need to update your app, just open the existing app and you should see the new menu in the top right. However, if you're still on Tesla app 4.29.5 or earlier, head over to the app store and upgrade to the latest Tesla app to see these new features.
