The closer your battery is to 50% at all times, the better. So for daily driving, I plug in below 45% and charge to 60% (I rarely go more than 10 miles away and work from home). BUT certain features like launch control only work above something like 75% SoC, so if I'm going for a spirited drive...

Buy this. It will handle ALL J1772 extension situations, no matter what kind of pigtail you have attached to your charger. The alternative would be buying extension cords for each and every plug you need one for. Buy this and you're covered no matter where you are trying to AC charge...

I have the Porsche Wall Charger and it is fantastic and at a surprisingly good price for a Porsche branded product. It doesn't suffer from the quality issues of Porsche's mobile chargers. Software updating when I first installed it was difficult, but later firmwares (that it probably ships with...

Yes, UK and US have differing voltages. Here in US we have 240V most places. Except some locations have 208V. Not sure about UK. My stats were for my location. Just illustrates the importance of OPs location in this discussion, which I hadn't considered.

8.7 kW is indicative of 40 amps (50 amp breaker) with about 10% loss typical from the EVSE to the car. 7.4 kW is indicative of closer to 35 amps, which is a very odd number (could not get that from 32 amps for sure). The 5.8 kW suggests that the issue is not the charger being set to 50%, because...

Well? What was the outcome? Do you still need help?

As previously posted, I found my solution with the Home Assistant integration. It just took a simple script and it works exactly as I want. No calculations required!

@WasserGKuehlt @Alfa @laua - I found a solution. There is a Porsche Connect Home Assistant integration. Check this out...

My thermostat has a savings slider on it. It has five savings settings for time-of-use peak hours. - Maximum (4 degrees pre-cooling, 3 degrees setback) - Enhanced (4 degrees pre-cooling, 2 degrees setback) - Balanced (3 degrees pre-cooling, 1 degree setback) - Basic (2 degrees pre-cooling, 0...

Yup, exactly, does not solve the problem. The reason I want it to start right away is because I want my car charged ASAP (subject to charging with off-peak rates). Maybe a pair of scenarios will illustrate why this matters: Scenario 1 (not desirable, way it works now): Charges based on timer...

Yes, that's what setting a minimum charge will do. The problem is that when set up this way the car starts charging immediately. If that is during peak rates, I don't want it to do that. I want it to wait until peak rates begin at 11pm.

I have good news for you... it's in navigation settings under charging plan.

The simplest fix would be to add a "maximum charge". Then you wouldn't even need a stupid timer to define when you want it to finish if what you want is "ASAP!!!". Then, using the existing minimum, it will charge to that right away, then wait for preferred charging hours to start, and charge to...

That's exactly what I would expect it to do. Because you don't have a charging timer set on the weekends, there is nothing telling it to charge past 85%. That's exactly how it's designed to work. And it charges to 85% as soon as you plug in because that is your minimum charge.

Optimized charging requires other external hardware and software... which I believe is Home Energy Manager and/or an integration with your utility. Otherwise, it has no effect on charging behavior. If you read the manual it says it works "in conjunction with suitable charging equipment" it can...

Ok, I agree with you that if I set the minimum to 25%, it won't start charging right away. But I believe without a charge timer, it will start charging at 11pm and charge all the way to 100%. Otherwise, how would it know I wanted to stop at 85%? In fact, there would be nothing even set at 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...

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...

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...

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...
