80% to 100% how long

[Attica]

2023 model y long range how long does it take to charge at home using A tesla wall connecter set to 48 amps before going on a trip
specifically from 80% to 100% I haven’t take a road trip in it yet but soon will be
Should i charge beyond what the car recommends at a supercharger

If you are trying to limit time the battery is at 100%, I use the off-peak charge scheduling to finish about 30min before my departure. Let’s the car manage when to start charging in order to finish at 100% right before you leave.

For your question about the super charger - car charges faster when at a lower charge state, so going above like 70% makes your charge stops a lot longer. More frequent stops with short charges would be faster.

80-100% on L2 will take the same amount of time as 60-80%. On 48 amps that’s probably about an hour and a half.

You can just set your charge limit temporarily to 20% higher than your current state of charge while it’s charging and see how long it estimates.

But as previous poster said, if you’re trying to time it and make it finish by a certain time then just use the scheduled departure and off peak charge setting both set to 15-30 min before you want to leave and the car will figure it all out for you.

2023 model y long range how long does it take to charge at home using A tesla wall connecter set to 48 amps before going on a trip
specifically from 80% to 100%

The car will charge at roughly 43-44 miles per hour, depending on your specific voltage where you charge at home

=======================================================



Vehicle Charging Speeds
For the fastest home charging, install Wall Connector with a circuit breaker that matches your vehicle’s onboard charger capabilities. To view the max amperage of your Tesla vehicle, tap the lightning bolt icon on the touchscreen. To determine the max amperage of your non-Tesla electric vehicle, refer to your vehicle manufacturer’s guidance.
For unique power situations or when power may be limited, Wall Connector can also be installed with lower amperage circuit breakers to support almost any existing electrical system.
Refer to the following table for Tesla vehicle charging speeds for each power level option:

Wall Connector Technical Details	Charge Speed Max Miles of Range per Hour of Charge*
Circuit breaker (amps)	Maximum output (amps)	Power at 240 volts (kilowatt)	Model S (mph)	Model 3† (mph)	Model X (mph)	Model Y† (mph)
60	48	11.5 kW	41	44	35	44
50	40	9.6 kW	34	37	29	37
40	32	7.7 kW	27	30	23	30
30	24	5.7 kW	21	22	17	22
20	16	3.8 kW	14	15	12	15
15	12	2.8 kW	10	11

====================================================

Assuming your model Y has the max range listed (329, 330) that would mean at 80% is roughly 264 miles showing on your car. Thats 66 miles of range to replenish, or, as @E90alex pointed out far more efficiently, in less words:

On 48 amps that’s probably about an hour and a half.

The rest of the advice already provided I will just +1, to save on more words (lol).

I gotta say, I disagree with a lot of the posts here. In my limited experience, that last 2% from 98 to 100% will take much longer than usual(even longer than usual L2 speeds). That said, unless you are really in need of those last six miles of range, who cares?

And others are right, in that on a roadtrip, you really want to be arriving at superchargers at a very low SOC(state-of-charge), like 10%, and charging up to 70% or somesuch, to get the fastest charge speeds and overall shortest trip time.

I have only charged to 100% a few times, but sometimes it can take a long time at 100% to "balance the cells" (although it wont say that, it just appears stuck at 100%), and sometimes it can finish right away at 100% if it determines it doesnt need to do that. I have charged to 100% maybe 6-7 times total over my 5 years of ownership, and a couple times it "stuck' at 100% for up to 45 minutes, while others it finished like like 5 minutes after hitting 100%.

For myself, I determined that if I was going to charge to 100% anyway, I might as well let it finish, so I timed it so that it would be done about an hour before I wanted to leave.. but I also dont think any of this is something someone must do, since they really only need enough to hit the first supercharger stop + "a buffer they are comfortable with".

Well, OK. I think there's kind of a perception difference of what people mean by "finishing" charging. At that very end, when it switches to the mode of balancing the cells, yeah, that can take some very long and unpredictable amount of time, like another hour or two hours. But during that balancing time, it's not adding any more range, so that's where most people would say it's already effectively done filling up, even though it won't show the message "Stopped Charging" on the screen for a while yet.

It will take SIGNIFICANTLY longer to charge from 80-100% than 60-80%. Somewhere after 90% it will drop the amperage down from 48. I've seen it take about 1.5 hours for 90-100% alone.

Unless you really need that extra 10%, I wouldn't bother. Whenever I do a road trip where I know I will supercharge along the way, I don't bother as that extra 10-20% (unless needed to make it to the first stop) just means I'll be pulling into the supercharger with a higher state of charge which will equal slower charging and a longer stop required. I typically do 90% on my first leg of a road trip and then never above 80% (if that) for the rest of the road trip.

When leaving for a road trip I charge to 90% the night before, and when I wake up in the morning, set it to 100% and let it charge to whatever it can whilst I am getting ready for the trip, and do not worry about it any more than that.

For daily driving I charge to 70%, which for my needs is more than enough. I usually wait until the car is down to <40% to charge unless I know I am going to be driving a lot the next day. Tessie says my MXP Tessie has 6.2 degradation in 23,000 miles and 17 months.

I've never gone to 100%, and I normally charge to 80%. When I head up to Flagstaff from Phoenix (120 miles, 5000 feet elevation gain), I have been charging to 95% the morning I leave. Let's say I leave at 9am. I get up at 7am, start charging from 80 to 95%, and it's done before 9. I have been surprised that the A/C charging time doesn't seem any slower up to 95. 100 is another story. DC fast charging is definitely another story.

With your wall charger set for a 60A breaker (48A charging) on a standard 240V circuit (as opposed to the less common 208V), L2 charging of our Y LR is roughly 50 minutes for every 10% of battery charging. L2 charging stays extremely linear at that rate until you reach around 98%, then starts tapering back quite a bit. The last 2% or so can take quite a while (roughly an hour sometimes). So 100 minutes for 80-100% is a good rough estimate, knowing you won't quite reach that 100% due to the slowdown for the last couple percent. We charge ours to 90% the night before a road trip, then turn it to 100% when we awake in the morning and use the app to schedule departure an hour later: within an hour (enough time to load the car and eat breakfast), we're near 100% with a warm cab and warm battery. After 5 years of ownership using this approach and a couple road trips per month, we averaged 1% battery degradation per year (great!)

I always charge beyond the recommendation at a supercharger, making sure we arrive to each destination with at least 20% or we have enough charge to reach at least 2 different supercharger locations. We used to follow the supercharger recommendation. However, we live rural, 60 miles up a mountain road, and had a situation where there was a SWAT team blocking the road with only ten miles remaining, so we were forced to turn back. That was a fingernail biter where we barely had enough charge to reach a destination charger at a casino 50 miles back down the same road. I charged for 1.5 hours at a pathetic 30A/208V chargepoint charger while my spouse went in the casino and came back out $200 ahead, 1.5 hours later. That gave us enough charge to get to the next supercharger - and we were $200 in the positive, so not a bad day after all, but now I like a little extra cushion whenever we supercharge just in case. After 5 years of road trips, a little extra charge has been a 'lifesaver' a few times when things went wrong, like the SWAT team, an exit to a supercharger was closed, or all the superchargers at a location were all failing one day (happened only once in 5 years). So following the supercharger recommended charge percent really depends on how much you believe in Murphy's law...
