Do I really need to stick to recommended charging range of 20-80% ?

[SanJoseNinjya]

Got my first Tesla 2 weeks ago. The efficiency is not bad at all, 358Wh/m during the first 300miles(driving very slow tough). but its very inconvenient if I follow 20-80 rule. basically range is ony 150miles.
question is what will happen if I do 10-90? i know it might damage battery, but how much? any data ?

Before a road trip you are fine to charge to 100% and use to 10%, although be careful about running out of range before you get to the next charger.
150 miles of range is................tough to live with

For the longest time I charged my Model 3 to 90%. I’ve dialed it back to 85 or 80, and sometimes 90. Running down to 10% is fine.

Okay, now as a practical matter, I’d never start my day around town with less than high 20%. If you want to take advantage of Sentry Mode (security) or remote A/C or heat, you’re going to need battery power for it. That’s one of the perks of the EV is the ability to do those other things. It takes battery (and thus range) to do it. There’s just no practical benefit to running it that low on a day in day out basis (Unless you were having to go to a public charger as opposed to your garage).

Unless you’re towing something or driving very fast AND in very cold weather, you’re very unlikely to only get 150 miles of overall range on a nonstop drive if you’ve charged all the way up. Possible, but not likely, unless you’re on a lower range Tesla.

unless you’re on a lower range Tesla.

Compared to most models Tesla sells, the Cybertruck is a lower range vehicle.
If the OP is charging from 20-80% they are going to get 150 miles in good/average conditions, they will get less than 90 miles of range when towing, and could get under 100 if cold or driving on the highway.

You can go down to 0% if you’ve got the nerve hahaha. That won’t damage the pack.

Degradation is accelerated by spending time at high SoC, so charge above 80% when you’re going to immediately depart.

Really we are at a no one knows on this cell tech yet. So anyone quoting stats is 18650 or 2170 talking. Not the new batteries. Yes Tesla recommends

So do the standard till we know. Try to limit charge state high for extended period, and if you can try to time departure shortly after achieving high charge state.

So if one is going to 90 or a 100. Try to time with departure. Lower charge state is not a problem with the above mentioned cells. @akee at the other forum would be glad to give anyone a primer on why lower charge state isn't bad. Please tell him I sent you. He lives in Norway and is smarter than a ....

As other notes pour in. It really doesn't matter how you drive. Sure you could do better, but the question here is the battery. Lets not get into two different conversations.

Can the OP go from 90-10 and not worry about it? As he/she/it is concerned about damage to battery. The OP's Wh/mi is not relevant.

I’m an unabashed fan of these cars (and now truck), but I’m also a fair critic. It’s simply not true that the Cybertruck as a whole is a lower range vehicle. Just not true. Sure you can get a Model S with ~400. Other than that, if you have all season tires, then the AWD Cybertruck is the 2nd highest range. Maybe I missed a trim in there for one of the other models, but it’s certainly fair to say that the majority of the trims have less range than an AWD Cybertruck. And sure, right now you can only buy it with A/T tires, but that doesn’t mean that the truck itself is a lower range vehicle.

OP didn’t ask about towing. I qualified my point about towing or very cold weather.

To get back to the OP question, day in day out, there’s just no benefit to ending the day in the 20’s percent-wise and not charging it up unless you don’t have access to a charger. I’d say the same for going above 80. Why do it? That’s why I’ve dialed mine down to 80 from 90. But keep in mind, Tesla used to recommend 90. And 85. And 80. As they learn stuff, they update their materials and that’s a benefit.

OK, so looks like its important not to keep over 90% status in any circumstance for high side. Then I will keep min 20% for my next road trip to Tahoe where its cold.

Real world experience — The Model X I still have from 2016 maxed out at 256 miles of range when new. Now it maxes out at 184 miles. Never followed any charging recommendations. Charged to 100% every time, because yolo but really because you never know when you need to go somewhere in an emergency. Having the car sit both unplugged and also plugged in at 100% charge on that X saved me more times than I can count. It’s worth it. Nearing 200k miles on it. Planning to treat the CT the same.

I think battery technology was different between the ‘16 X and the ‘18 M3, so this isn’t a completely fair comparison, but charging to 80-90% and only once to my knowledge having it sit at 100% for more than a couple hours, my range maxed at 310 brand new and it’s now able to max at 286 (per the Stats app right now). It had dropped into the high 270s, but it’s back up to mid 280s again.

I would prefer to refrain from the words not. I have dozens and dozens of charges to 100%, and my car has 275k on it. 11%. degradation. Charge to 90%, but I drive over a hundred miles every day. My car never sits a high charge state too long.

Long and short of it. If one can keep the charge state as low as you can as one uses. So if you need 80% most days use 80%. If it is 90% on a regular basis 90% it shall be. Just try not to charge it to 90% if you only use like 10 or 15% a day. If one uses very little 50% should be a great spot, as one's truck is basically a garage queen.

Many fret about using the lower third of the battery, but stats don't back it up. Tesla's BMS does plenty fine. Again the AKEE fellow will tell you its calendar ageing along with state of charge.

Now lets circle back and again say with the new 4650's we don't exactly know, but one can assume similar behavior. So use the truck and you will be fine.

If you’re worried about range charge to 120%.

When Thor used lightning on Iron Man, I thought “wow, that must be killing his range”

I think it's a bit silly to worry about when it comes with a 150,000 mile/8 year powertrain warranty that includes early death of the battery.

Just charge it as high, and drain it as low, as your daily needs require. It goes 0-100% for a reason.
