Can we talk, for a moment, about profiles?

[dnanian]

I have to say, I find the whole Profile concept in Connect quite confusing. Not so much about how to select them, but rather, what they're trying to do.

First, rather than setting a maximum charge, you seem to be setting a "minimum" charge. If the Taycan is at or above minimum... it does not charge. I left it overnight: no charge.

So, if you set a "home" charging profile at your house, and set it for, say, 80%, it'll charge to 80% and stay there.

That isn't a "minimum". That's basically a charge target - a ceiling, not a floor as defined. What they say is:

So that that, at that point, the charging process "can be optimized", but it's not clear what they mean. Are they optimizing the charging? Do we do so by "activating additional charging settings"? What settings? Direct? Because that would just charge to 100% immediately.

Unless it's not doing it because the charge setting is set to "Optimized". Now, "optimized" does a bit of handwaving:

So, it seems to want to interact with other things to "optimize" charging, but...how? When left overnight, it did not charge. Should it have done so?

I find the whole thing vaguely baffling.

To set a Maximum, you need to set a Timer with a "Target" charge.

In Posche-Speak the word Target = Maximum.

Step 1: Learn German
Step 2: Move to Germany and live there for 10 years
Step 3: Profit (ie: understand the German ways so you can understand your car)

@dryii I think you are on to something.

The Charging in the Taycan is not easy to understand. The optimised Charging seems only to work with an extra installation in your house, Porsche Home Energy Manager. From the documentation I have seen for that you can set cheap rates of electricity and charge at non peak times. But quite an expensive add on.

The Taycan seem to set a minimum charge at anything between 25% and above. As you say the car will charge up to that level and pause the charging cycle. You need then to set a time setting when the car will need to be ready for use. Assume you set that time to 07.00 every day of the week and you can also set the level it should charge to at that time. You make an input via a slider. And then activate that profile. It works fine that way. If you need a charge during the day you can simply click on direct charge and it will charge up to 100% or wstop it and unplug.
Cumbersome way of programming charging I think.

I assume, I can just set the minimum charge to 80% for normal short journey days, then let’s say I’ve got a long trip tomorrow. I can set the minimum at 80% but set the charge timer to 100% for 7am. That way my car will charge to 80%, then at 4am kick in to top me up to 100% at 7am. ??? If it does that it is perfect for me. As I don’t want the battery sitting all night at 100%!

Yes, I recognize I can set a target charge for a given time. But given a profile, it suggests quite strongly that it'll manage the charging process, ensuring that you have "at least" a given amount, and past that it will be "optimized", "responsive" and "automatic".

Given their "Default" profile is 25%, they can't possibly expect people will "only charge to 25%" (and if they do, then that is an actual target - even though it's a floor.

So, that suggests that it'll charge over that amount sometimes. But it can't mean "only if there's a timer" - because there's no mention of that behavior.

It almost seems like this stuff doesn't work unless there's a Porsche Home Energy Manager involved. It certainly feels incoherent, and not because of a bad translation.

I don't even think it's available in the US. But it certainly mentions that we set "tarriffs" (aka rates) but there's no where to set those. (Here in MA we don't have peak and off-peak rates.)

Yeah - but you'd think those features woudl be explicitly linked, or at least referenced. The relationship between them, and the fact that there's no charging that will occur past the Profile floor unless one is set.

If this isn't fully redesigned (and it should be, but won't be), I would probably (read: definitely) have a section of the page that indicates not just what profile is selected and what timer, but exactly what to expect.

Cumbersome way of programming charging I think.

You're a master of understatement.

Yes, you set the "Profile" in this case to 80% (eg a "Home" Location profile). It'll basically charge to 80% all the time - and above that is controlled either by turning on "Direct charging" (no idea why this is a slider, but it basically means "fill 'er up"), or by establishing a timer and a target above the floor set by the profile.

Lots of unknowns with charging etc. I don’t have my car yet but I’ll probably create a you tube channel with short videos etc. Be something to keep me in the car!! Lol

What I think it is:
It's a general charging profile with a max charging level (25-100%) on any location and with the possibility of changing at certain times (for electricity at a cheap rate) or let the Home manager control it.
Just leave it unchecked if you don't want a minimum level (actually it's a maximum level).

I prefer to use a timer without a profile attached to it (unchecked).

What I did was set a "Home" location based profile with an 80% "minimum" charge. We don't have peak/off-peak here, so there's not much to "optimize". That way I'm always at 80% if I plug in.

Of course, another way to do it would be to set the floor/minimum to whatever you think is your "true" minimum (rather than your "working" charge), like 35% or whatever you're comfortable with as a "this is what I need at least" value, and then set a timer so that you're always "full" in the morning. But I'd rather control that by either plugging in or not plugging in. (This way I don't have to mess around to charge at a L2 charger outside the house, too.)

It'd be different with, say, some sort of automatic "plug connection" or an inductive mat, where I couldn't control the "connection".

That will get 100% always. It will immediately go to 80% minimum and keep going until 100%.

Unless you set a Timer with a Target (Maximum).

That's not what it's doing, though. It goes to 80% and immediately stops and stays there. No timer.

Do you have a "preferred charge time" set?

If your preferred time is set for 2200-0600 or something like that, it will immediately charge 80% (your minimum) then pause... until it calculates if it starts charging again, it will be done at 0600. So, maybe it will start charging again at 0430.

 

[Dambo]

There is a lot of talk about charging at home or at a station to 80-85% as opposed to 100%. Is there a simple reason for this:
1. Does it help maintain the condition of the battery?
2. Is it slower to charge the last 15-20%?
3. Does it proportionally cost more to charge the last 15-20%?
