So the charging to finish at the end of the timer makes sense from a cold climate point of view. But in case I would argue that only the time to leave is relevant. (Adding the start time to the UI just causes confusion for this use case)

To start immediately at the beginning of the timer is the more common use case to get take advantage cheaper night rate or solar at home.

Assume the following use case: one comes home early during the day from a road trip with an empty battery and solar at home. Because of the timer the car does not start charging until the very end of the tine window. It gets cloudy and solar efficiency is bad. Later that day some unplanned trip needs to happen (emergency, forgot something at the hotel etc.) so one gets to the car and it is not charged enough to make the trip.

So when I get frustrated it’s because the engineers tried to solve their problem during winter testing instead of solving (and in fact impairing) the common charing habits. This is not uncommon for engineers to do, it happens all the time in Software engineering.
The actual problem here is that this was not caught be the „release process“. Usually companies that are known for their user friendly experience and seamless „it just works“ architecture employ special UX designers and do focus testing to find these issues and feed the results back into the engineering process. This has not happened to a quality level that can and should be expected for a $100k+ car!

We also seem to agree that the preferred charging interval may be too short, and my assertion was that there is no way any user interface can go around that basic fact.
To be clear, I never placed a "value" - be it "good", "bad", or indifferent - on the length of any preferred charging interval or charging speed. I never assume it is sufficient or insufficient for a user. I am simply saying that if I want my car to charge ONLY during a specific timeframe, there is no way to program that. Timers don't do that, because there is no way to set the start time. I can ONLY set the end time. As you rightly point out, the car figures out the start time ASSUMING I don't mind when it starts. And I do mind. Lots of people seem to mind as evidenced by countless threads on the subject.

Bottom line... I should be able to tell the car "only charge between 12am and 6am" if that's what I want. They engineered it in a way that isn't even possible. Because there is no way to tell the car to charge only during a specific time, if I only wanted to charge off-peak, the only way to guarantee that is to manually plug the car in at the beginning of off-peak hours. If that's at 11pm (like it is during the summer on my utility's current rate plan), that's really inconvenient (considering I'm asleep then). Faster chargers and HEM and larger connections to the grid which are sometimes necessary in older homes to install a faster charger are all workarounds that many people have had to pay a lot of money to install just to make sure the timer doesn't start charging their vehicles prematurely at times they don't want.

Even if a driver owns a slow charger, they might be just fine charging only at night when rates are cheapest, because maybe eventually it's going to catch up (perhaps over the weekend?).... or maybe they also charge at the office... or maybe they take advantage of the three years of free charging at EA, or maybe they switch to driving a Prius when the SoC is too low. All of those use cases are not supported.

To me, a timer is a countdown - much like one you'd use on an oven. The charging interval is like a delayed start on a dishwasher (I apologize for the eye-roll-inducing analogies), and the combination of these two is meant to avoid the need for the user to do calculations of any sort (like energy needed etc. - imagine if you needed to calculate how much caloric energy needs to be dispensed for a roast to be ready when the guests arrive).
No disagreement on what a timer / countdown is. We totally agree on what a countdown is. I just DON'T WANT TO BE FORCED TO USE ONE that only has an end time on it. I don't want my car to count down to some imaginary "event" that never occurs. I want it to start charging immediately during the hours I set up and if it reaches 85% to stop. There is no way to do this.

Porsche's charging user experience sucks - that is all - kudos to those who can figure it out - it shouldn't be as hard as it is - and people are confused by it - these are not the hallmarks of good design.

So in your case you're "holding it wrong": set up a home profile with a minimum % set to whatever is a good safety margin for you - up to and including 100%. The car will start charging immediately upon being plugged in, and will stop when it reaches the minimum set in the profile.

So when I get frustrated it’s because the engineers tried to solve their problem during winter testing instead of solving (and in fact impairing) the common charing habits. This is not uncommon for engineers to do, it happens all the time in Software engineering.

It's got nothing to do with winter testing or preconditioning; nor is it related to lack of UX prowess. The previous paragraph tells me that it's more related to 'documentation' (as an euphemism for 'user education') - they took a bunch of user requirements*, and came up with what they (and me, for instance) thought was the best way to model it. Again, i fully get that what we (us two) may find 'useable' could be diametrically opposed.

*Except for @AmpedUp 's scenario, which I'll address separately.

Now I finally get it - you don't really care about battery charging levels (so essentially the car's condition), your requirement is that "the car should only charge during this interval". And yes, you are correct, the modeling of the charging functionality does not solve for this case.

Even if a driver owns a slow charger, they might be just fine charging only at night when rates are cheapest, because maybe eventually it's going to catch up (perhaps over the weekend?).... or maybe they also charge at the office... or maybe they take advantage of the three years of free charging at EA, or maybe they switch to driving a Prius when the SoC is too low. All of those use cases are not supported.
It really is the same use case - time-based charging. If I were to speculate, I'm sure this must have come up as a scenario, and was rejected. If you think about it, the feature would essentially say "delayed start + time-bound charging irrespective of power". So you may get a 'sufficient' amount of energy delivered - or not, but that is irrelevant. I'm not sure how to reason about this - and I'd poke a bit further as to why is time-bound charging so important: are you avoiding peak consumption (avoid overload), or peak rates? Would a proper EVSE (not derated to 20A) solve the issue?

In either case, I honestly find the requirement a bit odd, as again the condition/state of the car is completely left out - and isn't that the point of charging at home?

I don't want my car to count down to some imaginary "event" that never occurs. I want it to start charging immediately during the hours I set up and if it reaches 85% to stop. There is no way to do this.
I'm committed to (try and) help :). You may have read reports from our UK members of an app that integrates the rate schedule of a (specific) utility provider with the car's charging programming model. You're right in that there is no set-once solution for your scenario, but for a given state of the car, you can totally use the profile + timer functionality to limit charging to a specific interval. The formula would be trivial, it's 'programming' the app that will take labor. And there may be a set of predetermined profiles and timers that should cover most starting points - I'll be thinking about this.

To answer one of your questions... what was my motivation? My off-peak rates are about 6.6 cents per kWh and on-peak is about 25 cents. So it cost 3-4 times as much to charge on peak. Also during peak hours, things like cooking, ironing, and air conditioning usually used up the capacity in the house anyway (more on the reasons below), so cost was only part of the reason.

Here was my specific scenario and solution:

My old house was built in the 1960s, and the entire house got 60 amps from the grid. That's for everything... oven, stove, water heater, heating, and cooling. Needless to say, there wasn't much spare capacity for adding an EV. Since I was only planning to live there for two years while my new house was gutted and remodeled, I simply wasn't willing to invest in upgrading the grid connection. The most I could use without blowing breakers was about 20 amps, so I had to make due with a slow charge speed and charge only when temperatures were cooler outside and the A/C, oven, and stove weren't all running at the same time. So overnight / off-pead is what worked.

My solution was to get a smart plug that would turn on only during off-peak hours, and then set the minimum charge to 85%. Every time the car got power (which was now only during off-peak hours) it charged. Once it hit 85%, it stopped, even if it had power. So the rule for me was ABC... Always Be Charging (but only off peak). I got dangerously low on charge from time to time, and once or twice opted to take my wife's car instead of mine, but it worked.

EDIT: And by the way, now I have 80 amps Porsche Wall Charger and life is glorious. But the first several months of ownership was a struggle trying to figure something out that wouldn't blow a circuit breaker because my wife decided to use the iron while something was in the oven.

I figured, and thanks for clarifying. I wish I had seen the edit a bit earlier, but here it goes anyway - for whomever may find this helpful. (And I do invite 'code reviews'.)(I think similar formulae were posted previously.)

let Cap=83kWh (battery capacity)
StartT = 0 (12am, start of interval)
EndT = 5 (end of interval)
P = 240V (voltage)
I = 20A (current at outlet/EVSE)
StartSoC, EndSoC -> things we care about.
(using .9 for power delivered to the car)

If StartSoC is known:
EndSoC = (StartSoC * Cap * 10 + P * I * .9 * (EndT - StartT))/10/Cap

If EndSoC is known:
StartSoC = (EndSoC * Cap * 10 - P * I * .9 * (EndT - StartT))/10/Cap

Then one would set the min in the profile to StartSoC (along with the preferred interval), and the EndSoC in the timer, set to fire at or after EndT. The car won't charge outside the desired interval.

Huh? That’s how I had my car set up for the first year. It had a start time and target SOC. I now have it set up to simply have a target SOC and it will start as soon as I plug it in, whatever time that is,

Unless I’m misunderstanding your post, you might need to do some additional reading (and it is admittedly quite a weird / sloppy experience even if you understand it).

I think you understand my post (at least in terms of my desired functionality). However, I don't think you understand how the charging function works. Yes, if you program a preferred charging window, the car will charge immediately to the minimum and then during your preferred charging times, continue to charge to 100%. If you don't want it to charge to 100%, you can set a timer with a target state of charge for a certain point in time and it will start charging whenever it calculates it needs to start. For many people, this works fine, because the calculated start time is always or at least often after the preferred charging timeframe begins, AND they don't mind the delayed start due to the timer. For example, if your preferred hours are 10 hours a day and your charging time is typically 6-8 hours, it will charge within your preferred timeframe to your preferred SoC. However, there are two problems with the way they set it up.
- If I want to ensure it won't charge off-peak hours (other than getting to your initial minimum charge), you can accomplish that by not setting a timer. However, without a timer it will charge to 100%, because there is no "maximum charge" setting, or anything else telling it to stop.
- If I want to limit the target state of charge to - for example - 85% to optimize the battery life, I can set a timer set to 85%, which will limit the charge to that. However, with the timer function set, it will calculate the required start time, and if that start time is before my preferred charging hours, it will start charging during peak-rate hours regardless.

So the first issue with the way it is set up is that it forces the driver to choose... do I want to limit the target charge to less than 100% but potentially charge during the hours I don't want, or do I want to only charge during off-peak but potentially charge my car up to 100%?

The second issue with the way it is set up is that with the timer function set, the car delays charging. Could you imagine if you had to set a timer on your phone to say "Be charged at 6am"? And your phone is sitting at 25% charge at 10pm, so you set it on the charger and the damn thing wouldn't charge because of the timer? "Charging is on a timer and will start at 4:39am" it tells you. Or imagine you get an emergency phone call at 3am and need to leave the house, but your phone is nearly dead because the timer has delayed the charge. No... you want it to start charging right away so it is ready for use!

Obviously, I don't care if my cell phone charges during peak hours because it consumes hardly any electricity. But for my car I do care. And when it is plugged in and it is off-peak hours, I want the thing to start charging immediately when off-peak starts, not at 2am. During certain times of the year, off peak starts at 8pm. I might still need to go out for ice cream with my kids at 9pm, or go to the midnight showing of a new movie on the day it comes out, or drive my sick kid to the emergency clinic at 2am when it calculates it should start. So instead of waiting, why can't my car start charging at 8pm so it's that much more ready for me to drive at 9pm or 11pm, or 2am when I might want to use it? Because of a stupid timer that is counting down to 5am, which has no correlation AT ALL to when I actually might drive my car next. It only correlates to when my electricity rates increase.

The frustrating part of all this is the simplicity of the fix. Just separate the timer function (which readies the car for driving at a prescribed time... primarily useful for cold climates) from the charging function (set a minimum, maximum, and allowed charging times). This would continue to provide for the people that the current setup works well for, AND would solve the issues facing people like me. It would also be far more intuitive. Right now, it only works for people that don't care when the car charges, or don't want the car to stop charging at a particular SoC. For people that care about BOTH, it doesn't work.

StartSoC, EndSoC -> things we care about.
(using .9 for power delivered to the car)

If StartSoC is known:
EndSoC = (StartSoC * Cap * 10 + P * I * .9 * (EndT - StartT))/10/Cap

If EndSoC is known:
StartSoC = (EndSoC * Cap * 10 - P * I * .9 * (EndT - StartT))/10/Cap

Then one would set the min in the profile to StartSoC (along with the preferred interval), and the EndSoC in the timer, set to fire at or after EndT. The car won't charge outside the desired interval.
Yes, by checking the start and end times for off-peak, charge rate, rough estimate of efficiency loss, and my start SoC, I could manually calculate the percentage I could reach if I charged during all available off-peak hours. If that day it was more than my targeted SoC of 85%, then I could just set a timer for 85% at the end of off-peak hours. Then the car would start charging sometime overnight and complete at 85% as desired. If the percentage it could reach was less than my desired SoC, then I could modify the timer set for what it could reach by the end of off-peak hours, rounding down to the nearest 5% (since you can only do 5% increments). Let's say I calculate it could only reach 78%. Then I could set a timer for 75%. Then the car would start charging soon after off-peak rates begin and stop charging at the end of off-peak rates finishing at 75%. It would work... but obviously this is a high-effort workaround. It also still won't start charging immediately at the beginning of the timeframe (because of the rounding down of target SoC you'd need to do), though the time delay would be small. It also would cause a small percentage of the possible charging to be missed (e.g., 75% instead of 78% it could have reached).

If they would just add "maximum", then you could use the existing "minimum", "preferred charging hours", and new "maximum" to do exactly what you wanted immediately during preferred hours. I would use that and skip the timer altogether if a maximum was available.

I’ll be honest that I didn’t read beyond your first couple of paragraphs because you’re still saying something I know to be false. ? I have literally set my car up BOTH ways you’ve mentioned and it works. Is it horribly unintuitive? Yeah for sure, but I promise you it works. If I get out there later I’ll take a screen shot of my settings and post it here.

If you can get it to work, hats off to you!

Right now, super-off-peak starts at 11pm and ends at 5am. I want it to stop charging at 85%. Tell me how to program it such that all the following conditions are met:
- It will never charge before 11pm or after 5am
- It will start charging immediately at 11pm if below the desired 85%
- It will stop charging at 85% or 5am (whichever comes first)

If you post proposed settings, I will gladly try them and post my results. I'm 99% certain it doesn't work the way you think it does. I know from experience.

Right now, super-off-peak starts at 11pm and ends at 5am. I want it to stop charging at 85%. Tell me how to program it such that all the following conditions are met:
- It will never charge before 11pm or after 5am
- It will start charging immediately at 11pm if below the desired 85%
- It will stop charging at 85% or 5am (whichever comes first)

If you post proposed settings, I will gladly try them and post my results. I'm 99% certain it doesn't work the way you think it does. I know from experience.
On my phone so excuse the poor formatting. Here are my settings. It’s all about the minimum charge on the Charge ProTo achieve what you’re desiring, I believe you can have the same settings except for:

On this page, you’ll want to select Preferred Charging Period (11pm start & 5am end for you).

On the timer page, you SHOULDN’T need any changes but can select additional charging timers if needed. I simply have it set to run my AC and have the car pre cooled by the specified time.

If you have these set already and it’s still not doing what you want, then maybe I’ve glitched mine out by toying with it enough that it just gave up and happens to work as expected now. ?

The way I charged BEFORE getting our Rivian (thus adding a second EV) is exactly as described above, and so I’d plug it in and it would sit without charging until 10pm, and end at 6am (super low rate).

Now, with two EVs, I took off the time requirement so if I need to charge, I just plug it in. We changed to fix cost to avoid having to really baby it. I plug it in, starts charging for however long it takes to get to 85%.

I appreciate you taking the time to attempt to help. Unfortunately, it did not work. I tried the following with no timer...

And because of the 85% minimum charge, it started charging right away, at 5:30pm.

So I tried again but this time added a timer WITHOUT charging selected as you suggested just to see if that changed the behavior. I set the timer to 4:55am because it sometimes takes a couple of extra minutes to finish in my experience.

Again, the car started charging right away. The only difference this time is that it planned to have my A/C ready at 4:55.

I'm telling you, there is no possible way to get the car to start charging immediately at 11pm and stop at a specific percentage. The only way I found was by using a smart plug that made it impossible for the car to start charging until I provided power to the EVSE.
