If you'll read pack temps directly off the sensors you'll find that the car's temperature behavior doesn't always follow what the car's display is seemingly telling you. My observations are that when driven in moderate-to-hot ambient temps, the pack temp will generally stabilize (stop climbing...

Just passed 10,000 miles on my 2022 AWD Model 3. Per the maintenance interval spec, I took an hour yesterday and rotated the tires for the first time. Just curious... what kind of tire life should I expect? The OEM tires are a Michelin "Green," whatever that means. 18" wheels. Tire size...

Just a single data point... I'm on 2022.36.5 as of today. That release installed on 10/22/2022. No delay in downloading or installing. Just the typical 20-25 minutes that I've seen on every one of the 21 software updates I've had since picking up the car last March. My internet at my car is...

Depth of discharge is also a factor in Lithium-ion battery degradation. The typical ICE routine of periodically filling up, drawing down fuel over a few days, then filling up again when you're down to 1/4 tank isn't optimum for EV pack health.

The updated Energy app delivered in 2022.36.x neatly tabulates all energy usage. Works a peach!

Our Tesla's are far more like iPhones with wheels than they are like traditional, what-they-built-at-the-factory-is-what-you-get cars. And since any complex software always has bugs, waiting for "everything to be fixed" is a never-to-be-achieved fantasy. New bugs will be created even as old...

FYI, 2022.36.2 has a bug whereby it fails to ignore Sentry Mode at those locations (Home, Work, etc.) where it can be directed to do so. That doesn't directly affect you (OP), since you note that you keep Sentry Mode on at work. But since the bug involves the behavior of Sentry Mode, it would...

Why a new 12v battery would fail that quickly is hard to say. It certainly shouldn't. First question I'd have is the source where you purchased the battery. Online? A local shop? And if it was local, was it a place that specializes in automotive parts? Who installed it? All that relates...

I'm really liking 2022.36.2. Dropped a number of cool features on us. I especially like the enhanced Energy app. One bug of note in my 2022 Model 3 is that Sentry Mode is not ignored at Home. I was out blowing leaves near my car and Sentry Mode triggered. "No worries." I figured the update...

LOL. @KenC is definitely rocking that pack of his!

LOL. No, although I get that sometimes. :cool: You gotta use another vowel…

Roger that. No doubt NZ has its own electrical regulations. I was speaking more to the physics of electrical delivery, than regulation. "Continuous, sustained load" is going to behave the same everywhere in the world. I view that 80% usable as a physical property that NEC has simply observed...

A 15-amp circuit, which equates to a 12-amp continuous load, is far from ideal. But it should work just fine since NZ is on a 230v standard. Just a bit slower than a higher amperage circuit would be. I have my Tesla Wall Charger connected to a 240v/20-amp circuit, which gives me 16 amps. I'd...

There's a very long thread on the forum here (How I Recovered Half of my Battery's Lost Capacity) which discusses the whole question of charging patterns and how they affect both real pack capacity and capacity as reported via the BMS. As you might expect, most of the sources for the...

Lots of up and downs. That's what you'd expect with a trip like that. Short trips like a trip to your local school aren't going to tell you much. You're stopping and starting and accelerating from low speeds... actions which consume great gulps of energy. And, yes, if your normal use of the...

Your new charging regimen is much healthier for your pack than your old charging habit.

The 400+ Wh/mi over the last 4-5 miles is much, much too small a sample distance to draw any conclusions from. If you had a way to observe actual power output on a moment-by-moment basis, you'd see an astonishing variety, bouncing all over the place. You'd suddenly see that 1% grade on that...

There's no doubt that a major reason for Tesla's pre-heating of your battery while en-route to a Supercharger is to promote faster charge sessions, improving the user experience and getting you out of the stall as quickly as possible so it's free for the next person. But it's also true that the...

UPS dropped off my CCS adapter today. I had previously set up an account with Electrify America, but have never stopped there. Figured I ought to test it. Unlike Tesla's Supercharger network, which knows instantly who you are when you plug in and just automatically bills the card you've got...

All rechargeable batteries have an inherent useful life, typically stated in full cycles from 100% SOC to 0% SOC. Extending my earlier example of a 20% daily battery consumption, someone who charged their car to 100% and then let it slowly bleed down to 0% before recharging would consume one...

Could not agree more. Since the OP has access to his/her CanBus data, I'll just point out that the car collects and stores data that is much more useful for evaluating battery health than any over-the-road test could ever be.

Great question. Much of what we might do to preserve pack life involves balancing competing elements such as this. Although the general rule of thumb with SOC is that lower is almost always better, it's also true that it's the very upper end that causes the most cell stress. If someone was...

Beyond what's already been said, I'll just add that the degradation you (the OP) have experienced to date will probably be leveling out soon, if it hasn't already. There's also a hint that your charging habits may not have been your friend. Notwithstanding how cool road trips in an EV are, and...

Not all "grounds" are created equal. Part of that relates to things like the inherent soil resistivity at your home, moisture, temperature, building design - things you can't control. But part of it has to do with wiring/infrastructure topology, quality of materials used (wire, connectors...

Belay this earlier post of mine. I just awakened my car - not driven and not plugged in over the last 24 hours - and it's still at 56%... did not drop any. It's probably worth reiterating that cabin temp, as reported in the car or via the mobile app, is a "coarse" measurement. Rounded up or...

My original reason for wanting Cabin Overheat Protection was because the Owner's Manual suggests that when HVAC cooling is triggered, it also cools the battery (under Climate Control Operating Tips: "In addition to cooling the interior, the air conditioning compressor also cools the Battery.")...

FWIW, I updated to 2022.24.8 a day ago on my 2022 Model 3. After seeing this thread, I just awakened my car and found it has dropped two percent (from 58% to 56%) over about 12-14 hours. That's unusually high for me (for reference, a week ago I was away on a motorcycle trip and left my Model 3...

You can also awaken your car via the remote app on your phone. Just open the app and it will awaken the car (sometimes takes a minute).

I wouldn't jump to the conclusion that COP is the cause of your unexplained electric usage. My car spends several hours a day out in direct sun (no garage) and routinely triggers COP during the summer. I can't say that I can tell when COP fires up and when it doesn't (a cloudy day, for...

I have to laugh at the notion that watching rated miles is somehow predictive of whether I'll make it somewhere or not. Between the idealized EPA test suite that determined that rating, and the multitude of environmental factors that affect it out in the real world... and "rated miles" ends up...

I don't usually encourage 3rd-party apps - Tesla owners can decide for themselves what, if any apps they want to add. But in your (OP) situation, I would highly recommend Scan My Tesla. That app, in conjunction with the required OBD Bluetooth adapter, would allow you to monitor a variety of...

When choosing between two less-than-optimum charge requirements, I'm inclined to favor a high SOC level (90 or 100%), obtained with a Level 2 charger, than Supercharging. DC fast charging raises pack temperature considerably, and unless you're in an area with cold ambient temps, which will help...

Given that the 12v battery is likely to cause more difficulty if it dies in a Tesla than in an ICE car, it kinda makes sense to keep an eye on it. You (the OP) can proactively replace the battery (on your dime - the 12v battery is a consumable item and no one would expect Tesla to replace it...

Heat is probably the worst thing there is when it comes to accelerating degradation of Lithium-ion batteries. But that's a long-term factor and isn't going to manifest itself over a very short span of time. @dansev, it's much more likely that your change in driving pattern this summer is part...

Actually, I don't have central air. But, no, I was referring to people cooling (and heating) the rooms in their home when they are, in fact, there. The bedroom you sleep in, but then sits empty and vacant for the next 16 hours. The guest room. The dining room which gets used a handful of...

Roger that. Except that people do it all the time. It's called "central air conditioning."

I'd also add to what @jjrandorin posted... pretty much all of us who own, or are contemplating owning, a Tesla live in societies in which our individual carbon footprint is, relatively speaking, huge. Critiquing the "wasted" energy use of something like Sentry Mode or Cabin Overheat Protection...

Run SMT while you're pre-conditioning, on the way to a SuperCharger. And then again while you're actually at the SuperCharger. Hint: Tesla wants your Supercharging experience to be as quick and painless as possible. And most users, not knowing any better, think they want the exact same...

Your 12v AGM is a sealed lead acid type chemistry and is very different from the Lithium-ion HV pack the powers your car. Unlike Lithium chemistries, lead-acid chemistries LIKE full charge. And those aren't "charge cycles" (not complete ones, the kind we usually mean when we discuss them)...

I have the same issue as the OP. No garage. My TWC is mounted on the outside of a shed 100' from the house. I think some sort of awning is all that is needed. If you're not too worried about aesthetics, a piece of shower curtain material - the flexible cottony type - draped down over the...

Have you taken actual pack temp measurements? I've seen scant evidence that the BMS is actively cooling the pack at the temps likely generated with L2 charging. What I'll observe - on the Model 3 pack, at least - is that during the summer pack temps rise rapidly when the car is driven; and...

Your cost is going to be dictated by the length of the run and the difficulty of the run. And those will be dictated by what paths are available to you or an electrician. Do you have a crawl space? An attic? An unfinished basement? A finished basement but with removable ceiling tiles or...

Road trips in a Tesla are a joy! Completely agree with those who suggest letting your route and schedule dictate what you do. A single road trip, no matter what you do, isn't going to have a measurable effect on long-term battery health. That said - since you asked - shallower, more frequent...

Tesla does, indeed, regulate pack temperature. But not efficiently. And it makes no pretense about maintaining pack temperature at a level that is optimum (~20-25C) for pack longevity. My observations from frequent monitoring of actual pack temps, in a 2022 Model 3, during summer in the...

Aye, you'd think 12v battery test/replacement would be high on the list of things roadside/mobile service could provide. The benefits of lithium-ion over lead acid battery chemistries are well known. That said, I've always been kinda surprised when an automaker replaces their lead acid 12v...

I think it's important to remember that EVERYONE does some amount of "harm" to their EV battery pack. We charge to too high SOC, we Supercharge, we preheat before Supercharging, we use too much of the battery between charges, we park our car outside in the sun and/or in ambient temps that are...

Well, Tesla's own sensors capture several measurements along that line... Nominal Full Pack, Nominal Remaining, Full Pack When New (82.1 kWh in current Model 3's), and Calculated Amp-Hour Capacity. You'll need the Scan My Tesla app and and OBDlink device to be able to access your car's can...

Roger that, @jjrandorin. It's a dilemma, for sure. You see it on every single Internet forum, of every conceivable interest. Certain topics just naturally beg to be talked about... and so they pop up daily, if not hourly. If you pull them all into a single, coherent thread, that thread soon...

With all due respect to the author of Stats, he is a software developer focused on the very small subset of sensor data that Tesla chose to expose in the API they built for their remote app. And since that remote app was intended to operate a very few basic functions, by ordinary users, I would...

Glad you had a good trip. Road trips in a Tesla are the best! For your next trip, if - once you've plugged a destination into the Nav system - you'll bring up the Energy graph, you'll find it much more accurate than the default (EPA) numbers used by the Nav system and displayed at the top of...
