How to Schedule Charging at Home with a Standard Charging Station (Non-Porsche)

[tonysmart]

I need some clarification on how to schedule charging at home using a standard charging station (not Porsche).

If I want my car to charge only between 12:00 AM and 6:00 AM, it seems impossible to set this up via the Porsche app. Based on my experience, even if I configure these hours, the car will still charge outside this window to try to reach the target charge by the set time. This means it may start earlier or continue charging beyond the set window if the target charge hasn’t been reached.

Am I missing something?

Now, a charging station can instead be set to supply power only during the desired window (from 12:00 AM to 6:00 AM).

The question is: I’ve read in multiple places that this method is not recommended and that the car should always control when power is drawn and interrupted. Is this true? Could it actually damage the car? And if so, why are charging stations programmable?

Sounds like you need to set up a minimum charge to the Profile. See this video. To me, I'm still confused on the logic of the Profile, but this combo with a Timer works to achieve your desired effect.





I've never heard of damage of you like your smart home charger control the timer, it doesn't make sense why it would damage the car.

Lastly, using the Timer, I find it frustrating that the car does not begin the charge until the latter part of the Profile timeframe. It should charge at the beginning, then pause charging until any departure pre-climate settings is triggered that induces further charge. This allows the car to be ready sooner. Therefore, I have to set another departure Timer in between the time frame in the scenarios that I need to leave earlier. My prior BMW PHEV was not this complicated

Try this:

The following are my current settings for charging - Profile and Timer. I’ve been using this since the car was delivered and it charges to 85% by 0700 each day:

This has worked for almost two years of ownership.

Try this:

yeah this is exactly what I do but, looking at your setting, if I plug the charger in, let s say, at 8pm it starts charging right away and it does not wait 1am. This is my point. If in your case it works it means (i think) that you can deliver enough power (kwh) to allow the car to reach the required charge by 7am starting at 1am which is not my case unfortunately

This looks awesome! I would have never thought about all of this myself… I ll give it a try, Thanks!!!!

Ah - understood. I didn’t read your post properly. Hopefully the video helps.

Yes, you are missing something. You need to understand how car based scheduling works by design. First, make sure Direct Charging is OFF and that you are using built in General Profile that is Location independent as the baseline configuration. Then when the General Profile with Preferred Charging Window is setup with a value of 85% as an example, the car will behave as follows. It will start charging as soon as you plug in to 25% if the SoC at the time is below that, then it will pause, and wait to charge during Preferred Window. There is no way to overcome the immediate charge to 25% regardless of the settings. Try this out and let us know if you still have issues.

All right gents, I did exactly what the video says and it looks like it is working out as expected!
Thank you all!!!

That video is the ticket. I use a tesla wall charger with a j1772 adapter set up like this video and charge btw 10pm and 5am when its the cheapest and have the cor set to be ready at 8am. Works perfectly!

...There is no way to overcome the immediate charge to 25% regardless of the settings...

And this is why it's absolutely bonkers.

If my charge is below 25% and I want to charge in a cheap electricity perod, I either have to control the settings via my charger app / energy provider app, or wait until the cheap electricity period time before i plug-in.

Madness. Why don't Porsche allow the minimum charge to be lower?

We have been asked this question since day one. However, Porsche's view is that you need an emergency minimum of 25% before any other charging occurs to your liking controlled by Profiles or Timers.

I've been driving EV's since 2014 (Tesla, VW, BMW) and none of them are anywhere near as complex, confusing and unintuitive than Porsche. I don't understand how their software is so bad.
