Will my car charge tonight?

[Miketaycan]

I understand you are trying to help and that it may work as intended for you.

I want to only charge in off peak over multiple nights. Thats what profiles do and did perfectly for 9 months. Im not sure you have read this thread or manual either so its a bit patronising to ask me to do so.

Anyway - As reported further up this appears to have been acknowledged as an issue by Porsche - profiles don’t work as intended after the update. So you don't need to tell me im wrong again.

I'm waiting to hear from my dealer.

Good luck with that but the rest of us use as indicated.

Setting the minimum SOC works as ever, and is not the issue here.

Profiles have definitely been broken by the software update. Profiles do not now work as they used to, nor how they should. Porsche have confirmed this to me and said a software patch to fix the problem will be forthcoming but they dont know when.

In the meantime the “official” Porsche work-around using timers sort of works.You set the timer for a departure time which is end of your cheap nighttime rate . For many users this works fine and is the way they charged before the update anyway, so they notice no difference.

However the work-around does not work in a couple of circumstances;-

1. If you want to charge until the end of your nighttime rate (say 4.30am for Octopus users), then stop charging, then later start warming the car for a (say) 8.00 departure.

2. If your SOC is below a level where the car can charge to your desired SOC in one night. Here the work-around will start the Timer charging early (at peak rate) to hit the arbitrary departure time.

I just want to plug in and know the car will charge on cheap rate as much as it can, and no more. You cant do this simply any more.

I use a work around, for the “official” work around, whereby, if my SOC is low enough to need a multi-night charge, I manually reduce the target SOC in the Timer each night, so that it reaches the target SOC at the end of cheap hours and then stops.

The fact that I am even talking about a work-around for the work-around, is nonsense for a £100,000+ car. The profiles should be fixed

Point 1 can be achieved by having 2 timers where the second one simply manages the preheat / pre-cool.

I am having problems with my charger too. Had the car a week and no idea if it's going to charge or not. Even in direct charge I am getting the red error constantly - with the wall charger (EV Sync) flashing blue (waiting instructions) instead of flashing green if it's waiting on a timer.

Then suddenly and randomly (if I am lucky) it starts working again on direct charge.
Same on both ports.

But never during Octopus Go schedule.

No idea if it's the car or the charger (or compatability of the two).

Neighbour has got a Tesla and we are going to switch cars over today and see what happens.

Also the Porsche charger on trickle worked OK, so suspecting it may be charger related.

It's not the charger - the charger is in the car not the wall box (sorry, I know I sound like a long playing record).

Since you've proven the car can charge from a 13A 3-pin plug supply then (I assume this is your PMC+ / PMCC?) it does look like a conflict between the car and your wall box / charge point. If you have any profiles or timers then remove these and use the controls of your wall box for management. Equally try the opposite if you have wall box settings controlling the session remove these and use the timers and profiles on the car instead.

If none of this works and given you mention your Direct Charge works randomly then it could be a potential issue with your AC charge port (one of mine failed and disabled both - so it is possible) - but that doesn't explain the success of your 13A 3-pin session.

W1NGE to the rescue ?

I am working my way through the various car / wallbox options to see if I can get any kind of pattern.

I have watched the YT video for setting up timers and profiles and have even removed all these from both car and charger and still get a red error using direct charge, then randomly may go green.

The app on both car and wallbox have really long lag and don't agree with what the car says.

Yesterday the car went on charge on 45%. Car app said at finish 61%, Sync EV app said no charge delivered that day. Get in car and its on 80‰ (General profile)!

PMC+ was tried and worked fine on 3 pin as a test.

Will try on neighbours charger today (and him on mine) and see what happens.

Will update.

We all like a challenge!

Have you tried these obvious ones too:

1. Power off the Wall Box (leave it for a few mins)?
2. Check the manufacturer's website for firmware / software updates?
3. Is the Sync EV earthered correctly?

Interested to know what the fix ends up being.

 

[Fish Fingers]

So we try my Taycan on the neighbours wall box. All fine both ports.

Tried his Tesla on my Sync EV. All fine no issues.

Try my car on my wallbox... Turns green (both ports) and works like a dream!

No idea. But glad it's started to work again.

Next step will be to see if I can get it to use Octopus Go hours.

Obviously realised that it should behave itself when talking to a Porsche after being temporarily dumped' for a Tesla!

Perhaps it cleared some cache / buffer down during the shenanigans.

I had downpowered the 'charger' system a couple of times and rebooted it.

The app was up to date.

 

[mandoyoda]

FWIW, I’ve got the General profile applied to the Taycan to charge to 80%, whilst the EO Mini Pro 2 is scheduled to provide juice between 12:30am to 4:30am to match Octopus Go. It’s worked flawlessly so far.

 

[W1NGE]

I would still suggest using either the car or the non-Porsche charge point to manage any and all scheduling rather than mix and match.

Porsche profiles and timers work as advertised and at the end of the day it is the car which controls the charging and not the charge point / wall box.

I have a PMCC at home and access to a non-Porsche wallbox (was previously installed by a Tesla owner so not sure on make or brand) at my other 'home' location. My location based profile kicks in automatically as does the associated timer and has been trouble-free since the get go, so I'm confident the Porsche profile & timer controlled software is agnostic to any charge point / wallbox.

Whatever works but to simplify future troubleshooting, one or the other.

There is clearly an issue here.
The car correctly calculates that

-to go from 33 to 85% charge
-at 6.3kw,
-stopping at 0700 and
-starting again at 22.15

the battery will be charged at 23.55 tomorrow.

The issue is the charge won’t stop at 0700 as it should.
Nor did it wait until 22.15 to start.

 

[W1NGE]

SOC is 33% at start
Profile has minimum set to 85%
Logically charging starts immediately until the target is reached

To control the end time you must add a departure timer of 07:00.

I have adopted this approach since day 1 as this is how I interpreted the instructions.
