ARB6 - is your battery limited

[BigBob]

But I am pretty sure you have to select no timers or profiles (ie direct charge) to start with for the charge anytime app to be able to control the charging.
When I get my Taycan back from the body shop - they insisted on a full wheel alignment and can't get the car to go into the correct mode at their workshop to do it so far - I will do a bit more nerding on it.

Nerd away!

My general profile was definitely unticked so shouldn't have been active given the ovo thing. But changing it (and leaving unchecked) did seem to make the difference. Odd.

The best I get on my Turbo S CT with offroad-design-package ist 390 km at 100%.
Don't get that very often though...driving the car like a Porsche wants to be driven. ?‍

Where can I check which ARB is active?

Your Porsche dealer or a DM to ever helpful @ct14garage may reveal this. Regulator/government and the external Porsche systems are unreliable, the internal Porsche system is the authoritative source.

I tried over night last night and the charge - set to 85% in Ovo anytime - only went to 80%.
Looking at the Porsche app direct charging was off - I think this is perhaps how the ovo app sets when it charges.
I will try switching off direct charging before the timer gets to its target and see if it continues to 85%.
I am sure I have woken and checked early how it is getting on with a 100% charge - I only do tis infrequently - noticed direct charging was off, switched it back on and it did continue but too late to get to 100% I seem to remember.
I'll pay more attention next time

So I tried again last night.
I started off with direct charging set in the car 85% set in OVO anytime to be complete by 9:00 when I looked at 7:00 the car had had direct charging switched off, was reporting "charge process completed" but a line on the display at 80% and it had only charged to 80% during the off peak period and direct charging had been switched off.
I switched direct charging back on from the app but it was switched off again at 81% when I looked later so I switched direct charging off again with the app, we will see if it gets to 85% by 9:00

It didn't.
Probably as soon as the link between the Porsche app and the OVO app happened the hard line on the battery display re-appeared in the Porsche app and direct charging was switched off - presumably this is entirely coming from Porsche.

So, it no longer is a recommandation in UK to limit charging to 80%, but an actual imposed limit?

I would asssume some of you would qualify for a full warranty replamcent of battery now; 20% gone and battery degradation should bring it to below 70%.

Very interesting. Are you able to check what profile/timer settings arrive in your car when you make changes in the OVO app? - I'm wondering if Porsche is modifying the settings before they're delivered to the car.

I would also imagine (I am no lawyer) that it is now time for some legal action - in that the car is no longer fit for purpose and doesn't perform as per the contract made at point of sale.

I sat in the car and went through a few menu items this afternoon.
The car had a location dependant profile set at 80% for my address. I don't remember setting this myself (but that is no guarantee that I didn't) so I switched it off and we will see tomorrow morning if anything happens.
Since my last service I have been unable to switch the LCA, lane change assist, on since it no longer appears on the list of assistance items in either the left tube or the assistance menu.
Ironically I can still change the LED brightness in a different menu but the option itself has gone and certainly isn't working.

I had my scraped bodywork repaired and got the car back on Wednesday, just now it seemed like rear wheel steer wasn't working when I parked - more checking needed but it seems Porsche latest adjustments at the service changed my settings, with the 80% charge at my home address being perhaps one of them.

So this morning it stopped at 80% again despite me making sure there were no limits set in the car before I plugged it in.
There is a black line at 80% on the charge bar and direct charging has been switched off, presumably by Porsche.

So whatever I have tried OVO anytime does not charge above 80% and the means by which it happens seems to be by the software switching off direct charging when the charge level gets to 80% - I can confirm no profiles or timers are set in the car. If I switch direct charging off again in the Porsche app before the OVO target time is reached it does start charging but after 1 or 2% have been delivered it stops again with direct charging switched off again.

It is unlikely to be the energy company creating the limit.

I had thought the 80% was advisory and had used more a couple of times for long journeys but now can't find a way to charge at home for a long trip.

I am annoyed.

Weird isn’t it. I did manage to get mine going by changing things around. I think it was via changing the general profile to 85% and leaving it unchecked.

@BigBob @f1eng

I don’t recall how the OVO App works. But in the similar Octopus one, if you turn off ‘Smart Charging’, your Porsche App/PCM settings ‘take back control’.

To the same end, you may be able to just delete your charging parameters from the OvO app.

When I switched from OVO to Octopus a while back, OVO didn’t immediately stop trying to control the car’s charging. For a period of about a week both fought with each other to control the car’s charging.
I found smart charging has too many unreliable external dependencies so switched if off a while ago and just rely on the Porsche App/PCM.

Do you have a cheap night-time tariff? That is what I was going to go for but OVO don't offer one.
It would suit us fine, we have 2 plug in hybrids as well as the Taycan.

Hiya,
I'm in UK, MY22 CT Turbo, using Podpoint home charger and Eon Next Home (6.9p / KWh overnight). I have a long journey today and have charged to 100% overnight with no issues, so I'm guessing Porsche not limiting charge - hope this helps ?

Sorry, can’t avoid a long off topic answer.

On the surface Octopus Intelligent and OVO Anytime seem little different. I found their ‘intelligent‘ and ‘anytime’ offerings and their support for them both equally unreliable. With Octopus, if you find their scheduling unreliable you can turn off Smart Charging and control everything yourself. I don’t know if OVO allows you to do the same.

If you find OVO Anytime is unreliable and can’t switch off the ‘smart‘ part, OI does allow you to dumb down and ‘take back control‘ while keeping the cheapest rate.

Octopus Intelligent (OI) and OVO Anytime cheap rates are the same, 7p including VAT. OVO used to be higher but brought their price down to match Octopus (after I had switched, and after OVO said they wouldn’t match OI).

With OI you have to complete a 10 min Car integration test with Smart Charge turned on in their App but can then immediately switch it off and use their fixed 7p schedule, 23:30 to 05:30. You rather than them then control then control scheduling, using the Porsche App, PCM or your charger App. I’ve found the Porsche branded dumb charger in conjunction with the Porsche Appbut/PCM completely reliable. You just complete the Octpus set up quoting that you’re using a 32a commando socket - no Charger integration.

If OI smart charging is switched on, their systems will control the scheduling period to meet your target SOC and completion time. In theory you could end up with a longer cheap period than the standard 23:30 - 05:30 period. That could suit you if you need more cheap hours to charge more cars (depending upon on the size of your usual nightly refill. Also worth noting that whenever EV charging is cheap your whole household supply is also cheap - which also makes other battery storage or running other appliances off peak options - if you can be bothered.

Smart Charging needs reliable end to end connectivity between the Car and OI or OVO systems. Those systems also need to integrate reliably with a Porsche API (which is what could be influencing the max SOC). I found there were too many potential points of failure. After waking to find the SOC I needed had not been fulfilled too many times, I switched off the Smart Charging set up. At the time the Octopus (and before them, OVO) support team‘s advice was also unreliable. They tend to badge their systems as ‘beta’ - even after a long period of operation.

If you find OVO Anytime is unreliable and can’t switch off the ‘smart‘ part, OI does allow you to dumb down. You could timeshare charging across multiple cars, setting a series of charging schedules. Some dual connection chargers do similar by splitting their output, or if you can get more than 32a, you could use multiple chargers. Your 2 hybrids may have a lower charge rate and will have a lower battery capacity anyway.
