Effects of Winter on Tesla Battery Range and Regen

Winter conditions has begun to set in here in New England with temperatures not exceeding the 20’s. Thankfully I’ve already prepared my winter wheels and tires in advance so I’m not overly worried about the potential for snow, however I’m quickly learning the effects of winter on the battery and overall energy efficiency.
Cabin Temperature
The first order of business is making sure I’m comfortable when I get into the car each day. This means preheating the Model S cabin temperature through the Tesla App (if I happen to remember to) or, better yet, have it scheduled to automatically preheat via the VisibleTesla app.
My daily schedule looks something like this: VisibleTesla preheats the car 30 minutes before I enter and while it’s still plugged in from my overnight charge. This ensures I enter a warm car every morning with no affect on my range – the best of both worlds!
Leaving for work at the end of the day, however, is a bit more erratic so I usually use the Tesla App to preheat on an ad-hoc basis. I realize that this preheating will eat into my overall battery range, but I’m not overly concerned because I have plenty of range to spare even with a 100 mile commute each day. It’s well worth it for a little more comfort.
I enjoy turning on the air conditioner during the summer months but getting into a warm car in the dead of winter is even better!
Limited Regenerative Braking
Prior to the winter, the only times I have experienced limited regenerative braking (regen) was directly after performing range charges in anticipations of my Tesla road trip adventures. The Tesla battery does not have the capacity to receive additional energy (when at a 100% state of charge) thus it disables regenerative braking all together.
Winter months, however, bring a completely different experience with regen. When the Model S is cold it limits the ability to regen since the batteries need to be at an optimal temperature before it receives any additional charge.
A dashed yellow line appears on the center display indicating that regenerative braking is limited. If you’ve been accustomed to driving with regen on, this new behaviour (with regen disabled) will feel and drive very differently.
I found myself quickly rolling towards the cars in front of me as I instinctively ignored the brakes and assumed that the car would just come to a gradual stop by letting go of the accelerator pedal. That obviously didn’t happen with regen limited. You’ll need to use your brakes so be careful not to “over press” it as you quickly adjust to driving with brakes again.
This winter-induced form of limited regeneration lasts for a very long. I wasn’t sure if the lack of regen was isolated to the weather conditions for that particular day so I decided to log my results over a larger sample of several days.
Here’s what I noticed about the effects of winter on Tesla’s regenerative braking:
- There appears to be a linear easing off of the “regen cap” through the first 30 minutes. At 0 miles, when the car is just started, the amount of regen is capped at 20 kW.
- 25 minutes into my drive, the regen cap is loosened to 40 kW.
As you can see from some of my data points, it took me over 45 minutes of driving (30 miles covered) before the regenerative braking behavior was back to normal — that’s almost my entire drive home!
I’ve been experimenting with various approaches to avoid the regen capping. One of which is timing my overnight charge so that it completes right at the time I’m about to leave for work. This ensures that the batteries are at a good temperature, by the time I begin driving, and with no regen cap in place. Timing it perfectly can be tricky.There’s been a few occasions where my charge completed earlier than expected and as a result the batteries cooled off before I got to drive.Here again VisibleTesla can help, but it’s an area that I wish Tesla would address directly —
add a feature to allow users to specify the END time for a charge as opposed to the start time. The Model S should calculate when charging begins based on the set end time.
I’ve been experimenting with ways to reduce the after-work limited regenerative braking occurrences but since there’s no charging infrastructure at my work, I can’t pre-warm the batteries. I’ve even tried warming up the cabin temperature in advance to see if this would have an impact on regenerative braking but unfortunately it doesn’t.
Higher Energy Use
Cold weather definitely affects energy use on the Model S. My tires, while great for winter, are less efficient — they’re not the low rolling resistance tires that came with the Model S. I’m also using extra energy for warming the cabin (despite my chilly 66 F year-round cabin temperature setting). The Model S is also using extra power when managing the battery temperature.
Prior to winter my average energy consumption was around 300-315 kWh/mi but now I’m averaging 350-365 kWh/mi or approximately 16% more energy used than summer months. I’m also using my brakes more during the winter, as a result of the limited regenerative braking, so that will also introduce more wear and tear.
One piece of advice from Tesla is to use seat heaters to warm yourself up over cabin heat. The seat heaters apply heat directly to your body and thus a more efficient use of energy. If you have your cabin temperature set at 72 F , try reducing it to 68 F and use your seat heaters to warm yourself up.
I’m sure I’ll be uncovering a lot more tips and interesting findings over the next few months especially as the snow storms start blowing in and temperatures dip into single digits! Stay tuned!

Florida man charged after trying to hit Tesla protestors with car
Tesla protestors were nearly struck with the man’s car, though authorities say no one was injured.

A man in Florida has been charged with assault after attempting to drive into protestors outside of a Tesla store over the weekend, coming as the latest in ongoing protests and vandalism against CEO Elon Musk.
On Saturday, 44-year-old Andrew Tutil attempted to drive into protestors with his Nissan Pathfinder at the West Palm Beach Tesla store, although no one was injured, according to a report from Palm Beach Daily News. The store had around 150 protestors outside around 1:00 p.m., and Tutil reportedly drove slowly into the crowd before parking on the sidewalk and getting out.
“He drove into a crowd of senior citizens,” said Mark Offerman. “Everybody was able to move out, but two older women were really almost clipped. We immediately called the cops.”
After parking on the sidewalk where protestors had to jump out of the way, Tutil, a retired U.S. Army Captain, civil engineer, and supporter of Donald Trump, claimed that he was an employee of the Tesla store and that his brakes and electronics had malfunctioned, according to Offerman.
Palm Beach County records show that Tutil was later arrested and charged with first-degree felony aggravated assault with a deadly weapon without intent after police questioned Tutil and surrounding witnesses and reviewed photos and video footage.
The news comes as a wave of protests, acts of vandalism, and some violent encounters such as this one have been increasingly targeting Tesla stores in recent weeks against Musk and the Trump administration. Additionally, Musk’s work with Trump’s newly created “government efficiency” division has been a central theme in protests at Tesla stores, as federal workers have expressed criticism for the administration’s approach to “eliminating fraud and waste.”

The widespread protests began in January, after Musk performed what many said looked like a Nazi salute at Trump’s inauguration ceremony, and after he spoke at a campaign event for the far-right German party Alternative for Germany (AfD). During the rally, Musk said that there was “too much of a focus on past guilt and we need to move beyond that,” which many claimed was in reference to Nazi Germany.
The so-called “Tesla Takedown” movement launched over the past several weeks is targeting around 500 separate protests across 277 stores around the U.S. The Palm Beach protest on Saturday was just one of a handful in Florida alone, including those in Gainesville, Jacksonville, Merrit Island, and Sarasota, to name a few.
One protestor at a Tesla store in Colorado earlier this month told Teslarati that she was protesting Musk because she was “highly concerned that our Constitution is being ignored,” adding that “it’s dangerous to have power rest in a handful of ultra-wealthy people.”
Others at the event highlighted Musk and Trump’s attacks on queer, trans, and non-binary people, as well as the administration’s recent controversies with Ukraine President Volodymyr Zelenskyy, and claims that the President is aligning with Russia President Vladimir Putin, as a few of the major reasons they were protesting at the Loveland Tesla store.
Musk has mostly deflected and made light of claims of his alignment with Nazis, while the public has been polarized on defending or condemning these and other actions.
The Tesla CEO was defended by Israel Prime Minister Benjamin Netanyahu, who said he was being “falsely smeared” immediately following the inauguration event. While the Anti-Defamation League (ADL) also went on to defend the action as an “awkward gesture,” the group has since condemned some of Musk’s more recent posts making light of genocide.
Earlier this month, Musk reposted then deleted a screenshot shared by X user Rothmus claiming that “Stalin, Mao and Hitler didn’t murder millions of people,” but that “their public sector workers did.”
“It is deeply disturbing and irresponsible for someone with a large public platform to elevate the kind of rhetoric that serves to undermine the seriousness of these issues,” the ADL wrote in a response on X.

In addition to what have largely appeared to be peaceful protests at Tesla stores, a number of acts of vandalism, including graffiti, arson, and some even more violent assaults involving weapons, have been targeting the automaker’s locations around the world.
Multiple people were taken into custody following repeated arson and graffiti at a Tesla store in Colorado within the past few weeks, while multiple Tesla vehicles have been set on fire at stores, and one Tesla store has been shot at. Owners of Tesla’s vehicles have also been targeted in public, with some being captured on Sentry Mode keying or tagging the vehicles.
The Trump administration has also started labeling such attacks against Tesla as “domestic terrorism,” and the Federal Bureau of Investigation (FBI) has started investigating several of the events, including one involving two Cybertrucks that were set on fire in Seattle and another at a store in Oregon that was shot at twice in a few weeks.

Tesla Megapack project in NSW reaches $260M financial close
The latest Tesla Megapack project to be announced in Australia, with a $260 million financial backing.

Partners involved in yet another Tesla Megapack project in Australia have reached a financial close, as the upcoming site also begins construction.
On Monday, renewables provider Equis Australia announced closing on the $260 million deal for 138 two-hour Megapack units in Tamworth, New South Wales (NSW), set to back a 250MW/500MWh battery energy storage system (BESS). Dubbed the “Calala” BESS, Equis says the project will store enough power to supply electricity for as many as 115,000 homes during peak usage.
The Calala project is expected to become fully operational by 2027, and it will be constructed in two independent project phases, bringing 100MW and an additional 150MW online in sequence. Located about 5.8 kilometers (~3.6 miles) to the southeast of the Tamworth town centre, the Calala battery will be connected to the NSW grid using an underground cable leading to Tamworth’s 330kV Substation.

The BESS is also expected to create around 170 new roles during construction, and as many as seven ongoing positions upon launching operations. The first 100MW portion of the Calala project will be devoted to supplying a partnership with provider Smartest Energy, while Tesla’s Autobidder real-time trading and control platform will be used to manage and oversee energy transactions to make the 150MW project a merchant BESS.
The financial deal includes the sale of $260 million in non-recourse debt financing package from lenders Westpac, Societe Generale, and the Sumitomo Mitsui Banking Corporation. The agreement will also include a Voluntary Planning Agreement (VPA) for the Calala project to contribute a total of $2 million to the Tamworth Regional Council over time.
Equis Australia also has several other BESS projects, primarily located near its headquarters in Melbourne, along with those scattered around the Sydney and Brisbane areas. The company’s Australia branch says it has 16 BESS projects in its portfolio, along with 11 onshore wind projects, together which total 9.6GW of renewable energy capacity.
The renewable provider is also nearing completion of a massive 600MW/1,600MWh BESS outside of Melbourne sporting 444 Tesla Megapack units, which is expected to become operational later this year.
Currently, Tesla produces most of its Megapacks in Lathrop, California, though the company recently shipped its first units from a new Megafactory in Shanghai, China to Australia. The manufacturer has also begun building a third Megafactory in Waller County, Texas, just a couple of hours east of Tesla’s Gigafactory Texas.

Tesla Model Y inventory is going fast, selling out in many U.S. states

Tesla Model Y inventory is apparently moving pretty quickly as the legacy version of the best-selling car in the world is now sold out in many U.S. states.
With the introduction of the new Tesla Model Y, the legacy version of the vehicle is now no longer being produced. The units that are available are the final ones that Tesla will produce as it is sunsetting the old look of the all-electric crossover.
As production has stopped on this specific version of the Model Y, Tesla is offering some great deals on the vehicle…that is, if it is still available for delivery in your area.
Since the new Model Y has started production and deliveries, 29 U.S. states have now sold out of the old vehicle’s look:
NEWS: New Tesla Model Y inventory is now completely sold out in Texas, Michigan, Ohio, Illinois, Georgia, Utah, Virginia, Alabama, South Carolina, North Carolina, Tennessee, Mississippi, Arkansas, Kansas, Missouri, Kentucky, Oklahoma, Indianapolis, Iowa, Nebraska, Hawaii,… pic.twitter.com/hTZgDexgmE

Tesla is offering over $5,000 off of some of these Model Ys in an effort to move inventory and make room for the new Model Y at its showrooms across the country.
For what it is worth, the legacy Model Y is still a fantastic vehicle, and picking it up through inventory is still a great idea, considering it holds a lot of great tech and is now being offered at a great price.
In the United States, Tesla is still only offering the new Launch Series version of the Model Y, which comes with the company’s Full Self-Driving suite, some exclusive badging, and premium interior, among other things.
Until those lower-cost trims arrive, sales figures for the new Model Y will be restricted to the Launch Series trim. We likely won’t see a launch of Rear-Wheel-Drive or All-Wheel-Drive configurations of the new Model Y until the inventory of the previous version starts to dwindle down a tad more.
Launching those trims now would cannibalize the legacy Model Y vehicles, as most consumers would rather have the new vehicle with the upgrades than the older version — even if it means a substantially lower price.
