Can you help me understand “85% min”? If I want to charge to 85% maximum, why do they call it “minimum”?

I can understand the “immediately charge to a minimum level” to help preserve battery health (you don’t want to keep a battery with low state of charge low for an extended period of time). So “charge immediately to 25%” makes sense.

But “85% min”?
As I stated in the first post, I think a lot of confusion comes from wanting to set a max…and having no way to do it. 🤷‍♂️

The minimum setting is just what is says, a minimum.

If you are using preferred times, the car will charge to the min setting first regardless because it’s the min, and then charge to 100% during the preferred times. Note that this can exceed the min if the min is less than 100%; therefore it is not a max. ✅

If you have have both a profile and a timer setup, the car will charge to the min first, and then to the timer target charge. Note that this can exceed the min if the min is less than the timer target charge; therefore it is not a max. ✅

So, the setting is not a maximum. It is the minimum value to charge to immediately.

So, why did I suggest that setting if you clearly asked for a max?

Because if you have the active profile set and nothing else telling the car to charge more, then it only charges to the min and does nothing else (because it’s not being told to do anything else).

In this case, it behaves like a maximum setting (which also adds to people’s confusion). But it’s not a maximum setting. It’s a fake. A phoney. A fraud.

It is, as I said, a minimum. It’s just that, in that case, nothing else is telling it to go higher.

So, you want a maximum, but that doesn’t exist. So, I offer you a knockoff instead.

But, as Dave said, there may be additional problems with the smart EVSE.

I don’t normally use the preferred charge times, but I did test everything to confirm my understanding of the manual.

During my testing, the car charged to the minimum and then waited until the preferred time to continue charging.

Maybe post more pics? That usually helps more because I can see what’s actually happening. 🙂
Thank you, the situation is simple:
The charging is paused with the hint as attached. But there is no departure timer set. See 2nd picture.

......the Taycan can be thrown off by EVSE’s that have variable charge rates because the Taycan attempt to accomplish “just in time” - departure time - charging - in order to do that it has to estimate the total time rquired to charge and it can only do that if the charge rate is static - if the charge rate is varible - the car will miscalculate the charging time because it only starts to charge when it thinks it needs to, in order to meet the depature time - well if the charge rate is variable - that will confuse Porsche’s software and again you will have to spend time figuring out why the car didn’t charge overnight…
How does the Taycan do with EVSE's that do "load sharging" for mulitple cars? If you have, for example, a ClipperCreek HCS-D50 that is plugged into a 14-50, and provides 20A each to two cars, then ups it to 40A for the second car once the first car gets charged? That seems like a variable rate EVSE.

Based on this (limited) information, I would guess it’s just a bug and report it to Porsche, but there may be more I am missing. Sorry. 🤷‍♂️

Did it do anything any differently today?

Sorry I wish I could share more. I didn’t use the car it is still fully charged. I’ll share more soon. Are you aware of a self-learning algorithm determining an assumed departure time? Thank you for hanging in there.
