wall mounted charger

[Shug]

Others may correct me here but I'm not aware that the app knows about cheaper electricity outside the cheap window, such as when Octopus schedules a charge. To show "estimated" cost the app just works works with the normal times. I believe you'll need to check your bill to be sure.

Perhaps I am not being clear tophamn.

I plug the Taycan in

Octopus sometimes recognises, sometimes not, but when it does recognise the Taycan is charging, a shedule is created - example below.

The following day you can look at your electricity charges in the Octopus app and check the number of kW charged off-peak and peak, where it is very easy to see if the off-peak number matches the charge % increase and also if the peak charges are aligned with other days in the week.

As a rule of thumb every kW charged by Octopus should provide somewhere between 0.9 kW and 0.95kW to the Taycan battery.

The usable capacity of my larger 93.4 kWh Taycan 4S battery is 83.7 kWh, so for every kWh charged by Octopus, you get around 1.19% of additional charge at the Taycan battery.”

So much as it may surprise you that I am sometimes charged peak rate when charging my car, I can assure you that is my reality when checking in the Octopus app.

You _are_ being clear and thanks for the extra information - I wasn't aware that the app was clever enough to know when cheaper charging had been scheduled outside the usual hours. I've checked my own usage and see it clearly - so as they say: "every day's a school day".

I can't be sure but I suspect you're suffering from the effects of the poor communication between Octopus and the car. When I set up Octopus to contol the car I regularly experienced missed messages leading to either failed charging or a failure to stop charging. Have you been able to correlate the charging schedule provided by Octopus with the time the car is actually charging? - do they match?

 

[Shug]

It is sad to say that there is no correlation between the schedule that appears in the Octopus app and what happens at the car.

The times displayed in the Octopus app are I believe when they may charge the car, not that they actually will.

I also experience charging when the app advises there will be cheap electricity and I am charged at full rate.

I either need to go back to the old way charging which involved setting an off-peak timer and a preferred charge time profile in the Taycan app or car, or switch to OVO and experience the satisfaction that W1NGE describes.

Here's the issue i have with no start time available on my taycan. If i plug in my taycan to my andersen charger, the taycan starts to charge right away. If i set a schedule on the andersen to charge from 23.30-5.30, the app flags an error. It will not charge at all. I have to cancel the schedule, and plug in the taycan when i want it to charge.
Andersen is recommended by Porsche in the uk.
You'd think the apps would talk to each other.

That's fine - ignore the error and the car will charge when the wall-box provides power.

You have to use the EVSE / charger in dumb mode with no programming enabled whatsoever otherwise the Taycan will object.

Which model year is your Taycan <= 2024 or current 2025 onwards?

Please share images of your charging settings from the PCM.

What is your minimum charge level set to and typically what is the car's state of charge when you typically plug it in to charge at home?

Remember that the car controls the charging session and not the EVSE (actual charger is in the car) and so programming via PCM is key to avoid the errors you are seeing.

Totally understand the concept you have explained, as it matches my experience.
I generally charge when the car's reserve drops in to double digits. I then set the departure time for 5.30am which is the end of the off peak period. I usually set the car to charge to 100% and then plug in around 11pm ( off peak begins at 11.30pm) The car starts charging and the pcm will estimate a new final charge state depending on how low the original charge state is.
It charged to 90% this morning from a charge state of around 25%. Cost was less than £5.00!
If i had a long journey ahead, I'd plug in earlier, to enable a full 100% charge.
It's a minor inconvenience not to be able to plug in, and set a start time . Ok, the standard rate for power is 4x the off peak rate, but that figure is a third of what you pay on the road.

Btw, it's a 2025 CT 4s

Given you have a J1.2 Taycan (facelift) then the concept of the 'profile' has been consumed into the overall 'Departure Timer' and subsequent advanced settings otherwise I'd be advising to use a location based profile, minimum charge of 25% and a target charge of 85% between the hours of your off peak. Providing that there are no other profiles or timers active OR programming set on your Andersen then it should just work like everyone elses.

For your car I would set the following:

New Departure Timer:

1. Ready by 08:00 (or whatever)
2. Daily repeating timer (doesn't matter if you don't plan to charge each day)
3. Extended settings --> Optimised Charging set to ''Manual'
4. Preferred time period --> 23:30 - 05:30 (your off peak period)
5. Set target charge level - 85% (or whatever)
5. Save location (call it 'Home')
6. Enable the timer (disable any other active ones)

Sample video (doesn't show preferred times) - https://player.vimeo.com/progressiv...90e5e2fb126a1f37fe617457945179e3c47e998c1f0aa

I used the Ovo Charge Anytime tariff and didn't make use of the My Porsche App for charging configuration as Ovo provide their own (really simple). The difference here is that Ovo will communicate with you car (PCM) directly, EVSE agnostic and will automatically create, enable / disable timers as required to meet your target charge (£0.07 / kW). Requires a smart meter to be in place.

If none of this works then it can only be a software issue and unfortunately a dealership visit. Aside from that try a different EVSE (even a public AC EVSE and play with the timer controls to verify that you can control the start time etc.) If either of these work then it does suggest something conflicting with your Andersen (shame as they are one of the best).

Depending on what your minimum charge is set to the car will invoke charging regardless either to reach that minimum first OR pause the charging session (flashing blue charge port light) once it registers that the car is either at the minimum or above until the next timer event and then start either at that time or somewhere between that time and the end of your preferred window (it will calculate based on the power supply from your Andersen what these times will be). Going to 'pause' mode may take several minutes during which the charge port light will flash green so be sure to wait a wee while before assuming charging is active.

appreciate you taking the time to explain all this. I'll follow your advice , which I'm sure will work perfectly.
Thanks again.

Bingo!

OK - so I'll preface this with this will be my firs EV (and therefore obviously my first Taycan!) ........... so I may get some of the words wrong (and definitely ask daft questions!!)

I'm picking up my (used, version 1) 4S Cross Turismo on Saturday. I'll have a Andersson A2 charger installed at home (work was paying so "went for something nice"!). However - for a variety of reasons, I can't get this installed for about 6 weeks.

The Taycan I'm buying (from an OPC) comes with a Type 2 cable but nothing else. Putting aside my short-term home charging gap, my feel is it's wise to have a portable charger that can plug into a UK 3-pin socket (and bonus if it can plug into other types of sockets as well!) for when I'm out-and-about. Assuming this is the case - what mobile charger do people recommend? From reading here it would seem, whilst the Porsche Mobile Connect may meet my needs, a lot of people don't rate it

3 pin charging (13A) is good for 0.1 miles of charge per minute and so is "glacially slow". Single phase 32A dedicated supply will do the job nicely overnight with up to 7.4kW and 0.3 miles of charge per minute.

Your car would have been supplied originally with a Porsche Mobile Charger Plus (PMC+) at a minimum and would be ideal for home charging - ask the dealer where it is for starters.

Bear in mind that the noise on the forum re PMC+ or PMCC is just that - mainly from North America where there was an issue / recall of the PMCC (not in UK). I have a PMCC and flawless in 4.5 years. All will charge at the same rate and rely on the car to manage the charging process (not the PMC+ or and EVSE for that matter) so ignore the bells and whistles you might get with an EVSE model as 9/10 you will disable these features and let the car manage the charging process. Check also which provider you are using - OVO / Octopus - some of these may dictate the EVSE to use so that their service works with it if it can't communicate directly with the car (PCM connectivity). OVO can and I think Octopus can too (check the forum) but may need some settings enabled / disabled to avoid programming conflict.

Andersen A2 is a nice unit but the company is now believed to be unstable and has poor reports of customer service. Search this forum.

Personally I would skip anything interim until you get your home eco system in place unless charging locations are sparce in your area. Alternatively, source a PMC+ on e-bay (genuine bargains there) ensuring that is comes with all cables - crucially 2 supply cables - 32A / 16A and 13A 3-pin UK plug. If you follow this path then you really don't need the Andersen and really don't need to occupy precious luggage space with the EVSE and all related cables (just keep the public Type 2 in the underfloor compartment as many AC units aren't tethered (no cable).

Always DC charge when out and about as the stress of glacial charging will drive you insane. J1.1 Taycans are slower to charge (older battery chemistry) which is likely only noticable when DC charging and AC should not be any different.
