Electric vehicles (EVs) often get a bad rap for range loss in cold climates, but a new study of Teslas shows that cooler regions may actually be better for an EV’s battery over the long term.
On Monday, Recurrent Auto shared results from a study showing that Tesla vehicles owned and operated in cold climates had better average range scores than those in hot climates (via electrek). The study looked at over 12,500 Tesla vehicles in the U.S., using data Recurrent has access to through its software.
While the study found this to be true amongst multiple Tesla models and model years, the results were most prominent in the Model Y. In particular, Model Y units with the 2020 model year averaged range scores of 95 in colder climates and 92 in warmer climates, as can be seen in the following infographic.

Researchers gave the Teslas range scores to capture how much of a given EV’s range was still expected at the time of the study. A Tesla vehicle with a range score of 90, for example, would still have 90 percent of its initial range. Additionally, the study was conducted using the U.S. Department of Energy’s “hot,” “cold,” and “marine” climate designations.
As for why the study only included Teslas, Recurrent notes that they are the most common EVs available, garnering the most data. They also cite Tesla’s battery thermal management system, which they say offers great protection against environmental damage to the battery’s long-term health.
According to Recurrent, heat from the environment contributes additional energy to an EV battery’s electrochemical reactions, accelerating unwanted chemical reactions that cause the battery to age. It also says 86 degrees Fahrenheit (30 degrees Celsius) is the generally accepted threshold for accelerated battery degradation.
While range loss may occur in colder climates due to energy consumption from keeping the cabin warm, Recurrent says this is short-term. Because it does not have the same electrochemical effect as heat on an EV battery, the battery’s range will return once it becomes warmer.
Recurrent provides additional details on heat and long-term battery degradation here, and about the short-term effects of environmental heat here.
Despite the results, there are a handful of things Tesla owners in warmer climates can do to protect the longevity of their batteries. For one, parking in the shade or in a garage can help prevent the battery from heating up as much. When you need to park in the sun, Recurrent recommends charging only to about halfway, as the battery is a little more stable at that level.
Whether buying new or used, buyers may also want to consider newer lithium iron phosphate (LFP) batteries, as they tend to be more resilient in hot climates. Anyone purchasing a used EV should consider how that vehicle was stored and used during previous ownership.
Lastly, the researchers highly recommend owning a car with an active thermal management system, which owners should leave plugged in when not in use. According to Recurrent, this lets the vehicle initiate battery cooling at lower temperatures than when they’re unplugged.

WATCH: SpaceX attempts Starship’s tenth test flight after two delays
This evening, SpaceX has already stated that conditions appear to be approximately 45 percent favorable for launch. This is ten percent less than last night, when the mission was eventually scrapped around 7 p.m. local time.
SpaceX is set to launch Starship tonight, provided the weather cooperates and everything with the ship goes smoothly.
This is SpaceX’s third attempt to launch Starship for its tenth test flight, with Sunday’s and Monday’s attempts both being scrapped due to a leak and unfavorable weather conditions on the respective days.
This evening, SpaceX has already stated that conditions appear to be approximately 45 percent favorable for launch. This is ten percent less than last night, when the mission was eventually scrapped around 7 p.m. local time.
Propellant load of the upper stage and Super Heavy booster is already underway, and the launch is expected to occur at 6:30 p.m. in Starbase, Texas.

Tesla one-ups Waymo once again with latest Robotaxi expansion in Austin
Tesla’s new Robotaxi geofence measures roughly 171 square miles of Austin’s downtown and suburbs. This is more than double the size of Waymo’s geofence, which measures 90 square miles.
Tesla’s expansion of the Robotaxi geofence on Tuesday morning was a one-up on Waymo once again, as the automaker’s service area growth helps eclipse its rival in an intense back-and-forth.
A lot of conversation has been made about Tesla’s rivalry with Waymo in terms of the capabilities of its driverless ride-sharing service in Austin, Texas.
The two companies have sparred with one another, answering each other’s expansion, and continuing to compete, all to the benefit of consumers in the region.
Tesla expanded the geofence of Robotaxi once again this morning, and it is another growth that catapults it past Waymo’s service area in Austin — this time by a considerable margin.

Tesla’s new Robotaxi geofence measures roughly 171 square miles of Austin’s downtown and suburbs. This is more than double the size of Waymo’s geofence, which measures 90 square miles.
On July 14, Tesla officially overtook Waymo in terms of service area in Austin. But just a few days later, Waymo had responded with a bold statement, expanding from 37 square miles to 90 square miles.
Sarfraz Maredia, Global Head of Autonomous Mobility & Delivery at Uber, said the move “unlock[ed] another key milestone in Austin as our operating territory with Waymo expands from 37 to 90 square miles, which means that even more riders can experience Waymo’s fully autonomous vehicles through the Uber app.”
Tesla did not respond immediately, but it took its time with validation vehicle testing in the Austin suburbs, as we reported yesterday:
Tesla looks to expand Robotaxi geofence once again with testing in new area
Today’s expansion is perhaps the biggest step Tesla has taken in its efforts to continue to grow its Robotaxi platform. This is not only because the company has significantly expanded the size of the geofence, but also because it has ventured into suburban areas and even included Gigafactory Texas in its service area.
Waymo could come up with another timely response as it did when Tesla expanded in late July. We’ll wait to see what it comes up with, as this awesome competition between the two companies is accelerating innovation.

Tesla Robotaxi geofence expansion enters Plaid Mode and includes a surprise
Now, on August 26, the Robotaxi geofence has expanded once again, and is estimated to be about 130 square miles.
Tesla has expanded its Robotaxi geofence in Austin for the third time since its launch in late June, and the company added a big surprise with this new service area.
After launching on June 22, Tesla’s driverless Robotaxi service has been expanded three times. Its initial launch was about 20 square miles in size. The first expansion occurred on July 14 and was roughly 42 miles large, more than double the initial geofence size.
The second expansion occurred on August 3 and brought the total service area to roughly 80 square miles.
Now, on August 26, the Robotaxi geofence has expanded once again, and is estimated to be about 170 square miles.

The expansion of the Robotaxi geofence seemed to show the company’s focus on getting the service to the areas East and West of downtown was an utmost priority.
We reported on the Bee Cave region of the Austin suburbs being a place where Robotaxi validation vehicles were spotted testing in recent days.
Bee Cave is included in the new geofence.
However, that is not the biggest addition to the geofence, and it’s not even close. Tesla added a major area to the new geofence, one that fans of the company will absolutely love: Tesla Gigafactory Texas.

The big question that remains is whether Tesla is expanding the size of its fleet of Robotaxi vehicles in Austin. There have been many questions about the expansions of the fleet and not necessarily the geofence, and while the latter is certainly considered progress, Tesla will need to enable more Robotaxi into the vehicle population to handle the additional rides.
Tesla has been planning to do so, but is still prioritizing safety and does not want to rush any part of the Robotaxi process.
Tesla is also looking to expand to new cities altogether. It is currently moving toward a Robotaxi launch in Florida, Arizona, and Nevada, and has also opened up job postings for Robotaxi operators in New York.
