Tesla battery longevity is better in colder climates, new study shows
While colder weather negatively affects the range of Tesla electric vehicles and electric vehicles in general, it may actually be good for the long-term longevity health of EV battery packs, according to a new study.
Recurrent, which has access to data from over 12,500 Tesla vehicles in the US through its software service, has been releasing interesting new looks into Tesla batteries based on that data.
Last month, we reported on the data showing that Tesla battery longevity is not negatively affected by frequent Supercharging – putting to rest a long-standing myth about EVs.
Now, the firm is using its data to show how different climates can have an impact on battery longevity.
Recurrent assigns a “range score” to each battery it tracks; it is basically the percentage of range retention. For example, a Range Score of 90 would mean that the battery pack has retained 90% of its original range.
The firm has found that Tesla vehicles in colder and coastal climates have, on average, a better Range Score than Tesla vehicles in hotter climates in the US:
Extreme cold negatively affects the range of electric vehicles as active thermal management spends a lot of the pack’s energy to regulate the temperature. That’s well known.
But it’s new information, for me at least, that for the longevity of the battery pack, colder temperatures might actually be good – or at least slightly better than hotter climates.
Recurrent gives us a vague explanation as to why that might be:
Batteries are a lot like people – always aging. We can do things to reduce these effects, like exercise and sleep, or things that accelerate them, such as smoking and tanning. The same is true of batteries, and being exposed to heat is a lot like smoking cigarettes. Environmental heat contributes extra energy to the electrochemical reactions in the battery, which can accelerate unwanted chemical reactions that age the battery prematurely. The generally accepted threshold for accelerated battery degradation is around 30 degrees C, or around 86 degrees F.
Hopefully, this information could be useful to some Tesla owners.

EV charging company ezVOLTz has partnered with Driivz, the EV software arm of Vontier, to make its “Charging as a Service” platform even smarter and more reliable for fleets, businesses, and state and local governments across the US.
If you’re not familiar with ezVOLTz, it’s a full-service EV charging provider. It handles everything, from installing hardware-agnostic chargers to managing the backend with its software platform, ezCONNECT. Now, ezVOLTz is plugging into Driivz’s charging and energy management tech to help run things even more smoothly.
With Driivz’s help, ezVOLTz plans to keep its network humming with 24/7 monitoring and real-time issue detection. Driivz’s Alert Management System can auto-fix up to 80% of charger hiccups remotely without sending a tech on-site. That means more uptime and fewer headaches for drivers and site owners.
“EV adoption is surging, and drivers and the companies and entities that serve them need smart, connected, and reliable charging options,” said ezVOLTz CEO Sam Malhotra. “The Driivz team and their smart charging and energy management solutions are a natural fit in bolstering our services.”
The partnership also gives ezVOLTz new tools to grow its network. Driivz’s software tracks usage patterns and charger performance, helping pinpoint the best spots for new installations. Driivz will also support the ezVOLTz app, letting users plan road trips and find chargers nationwide.
“Reliability and ease-of-use are two of the most important considerations for EV drivers,” said Andrew Bennett, CEO of Driivz. “We’re proud to partner with ezVOLTz in delivering seamless and reliable charging to their customers.”
As more businesses, fleets, and municipalities plug into EVs, partnerships like this one aim to make sure the charging experience keeps up.

The Subaru BRZ may live on as an EV after all. Subaru wants its share of the sports car market, and an electric BRZ could hit the sweet spot.
Is Subaru launching an electric BRZ?
Subaru discontinued the BRZ in Europe in 2020 after the first generation. Although its twin, the Toyota GR86, was sold until the 2024 model year, the BRZ was released as a US-only model.
In its third generation, it could return as an EV. Speaking with Autocar, Subaru’s European head, David Dello Stritto, said, “Our options are open,” hinting that the BRZ could make a comeback in electric form.
Subaru’s global EV product boss, Inoue Masahiko, confirmed an electric version of the sports car “was under consideration.” He added that Subaru has extensively looked into an EV version of the BRZ with its partner, Toyota.
Masahiko explained that “We did consider electrifying the BRZ and GR86, but the win-win relationship is more important.” So far, “We can’t get the kind of benefits from both sides,” he added.
Subaru is already launching several new electric vehicles in Europe, including the new Uncharted, E-Outback (known as Trailseeker in the US), and an updated Solterra SUV.
Stritto said that an electric sports car will depend on the success of these models first, especially the Uncharted. According to Subaru’s European boss, the Japanese automaker feels “very positively about Subaru enthusiasts, but we need to see how Uncharted does first.”
As for an “electrified” powertrain, or hybrid, Masahiko said the vehicle’s packaging “would make it difficult,” adding an EV version would be “easier” to create.
The comments come after Stritto told Autocar last week that a new entry-level EV could also be in the works. However, that will also depend on how well the Uncharted sells.
For those in the US, don’t worry – Subaru is not planning to discontinue the BRZ. If it did launch as an EV, would you consider one? It would go up against the new Hyundai IONIQ 6 N and Tesla Model 3 Performance.
