How to use charging timers

[ct4s]

I guess you had Octopus controlling the car - I too found it very unreliable so reverted to have Octopus control my EVSE (MyEnergi Zappi - installed by Octopus). The benefit here is the car doesn't automatically start charging when plugged in - the charging window is controlled by Octopus so I always get the cheap rates. I then have a single profile where the "minimum" charge level is treated as maximum, and no timer set.

Yep, that's basically I do it. (I have a Hypervolt charger.)
Though I set the Octopus app to 100% and each car (Taycan and a Kia) is used to set the max charge %.

I never had an issue with a profile and a recurring timer - it just worked and was always 100% reliable.

When I switched to OVO Charge Anytime I then ditched the location based profile and associated timer for my main home and relied exclusively on the OVO app for controlling charging sessions. At my other location I continued to use a profile and timer.

Profiles on their own 100% never worked for me for whatever reason and that was on 2 Taycans both J1.1s.

... Eg, the ability to throttle charging speed (great for extending the 5p electric window to benefit the whole house when using a smart charge)...

I'm going to be "that guy" but you do realise this sort of thing is why Octopus are throttling back on the additional cheap windows they allocate? Basically people gaming their system.

I'd like to think other suppliers will step in to keep the market competitive, but with energy prices being what they are, that seems unlikely. So gaming it will kill it).

Agree somewhat. But ...

I only started "gaming" the system once they capped the cheap rate to 6 hours a day.
Before they announced the change, I mainly did overnight charging once or twice a week. Now I mainly do daytime charging for a little each day because I think about when and I how I use electricity more carefully.

Where will it end up - is someone gaming the system and will be banned from using a slow granny charger?

They evidently don't have the tech for that. Hence the sledgehammer to crack the nut and limiting everyone now.

It's a shame because for EV drivers it was a good deal. But people taking the piss with granny chargers (/throttling back EVSEs ) has forced their hand, it seems.

I guess they could have done something s/w wise... They know what car/EVSE they are connected to, and likely its capability...but they'd just be forever chasing the gamers, so why bother with the hassle. Nobody else offered this sort of thing AFAIA so not going to lose customers because of that ultimately.

Yes! Charging is working perfectly to 85% now! Thanks for the tips.

Now a new question popped up regarding charging. I drove today with PIRM and home was 3 km further than the batterylimit I set so of course I skipped the DC charging ( 1 minute!) that popped up in the trajectory.
At home put her on the wallbox. My battery temp was at 43 degrees Celcius and all the vetilators were maxing out to cool down the batterypack. I had expected the battery to precondition for the planned charging in PIRM but it didn’t. Is it a setting somewhere that I didnt find yet? I thought it would by default precondition if charging is planned in PIRM.

What is PIRM?

What is PIRM?

Porsche intelligent range manager. The system that calculates charging on your navigation route. This was the first time that I got to charging en route in the short time I own this car
It’s also the system that apparently has a lot of issues I see in this forum. So far, it never crashed on my Taycan though

I am in the same country as OP (never mind the flag ) and use homey now with great results.
Profile is set to 35%. So I know I can always drive 120-150km.
When there is a solar surplus (or in your case, dynamic prices are low), homey sets the Taycan charging to direct mode.
That means it instantly starts charging to 100%. Of course we dont want this so there is some logic in there as well that when the car reaches 85% or more it turns off direct mode and stops.

Now only thing is: I want this logic to work always, but sometimes I have to go somewhere more then 120km as well, even on cloudy days.
I just set a timer! Tell the car I need it at 1600 at 85%.
Now it charges on solar whenever possible, but it will regardless of solar power surplus be at 85% at 1600.

Homey plug in was made by a forum member here @IdleOverboost.

Generated 1.8 MWh last month, 69% went used right away, I’m guessing about 50% of that went right in the car because of this homey logic. Without any human intervention. Lots of cheap km.

Timer honestly is now the number 1 reason for me to pay for Porsche connect…
“22 J1.1

I would look into homey, or a smart charger that enables you to charge during cheap hours.
Make sure it’s MID for the ERE certificates

The timers are perfectly fine in my case. The tips and tricks got me exactly there. My wallbox is MID itself

But the second question that arose is about the battery preconditioning. It didn’t last night, am I missing something? See #36

Preconditioning is only for DC charging where the EVSE is 50kW or more.

Given you skipped the PIRM nominated charging location and not clear whether an AC or DC was the target I suspect the cooling wasn't optimised if indeed it was needed. When you got home and powered off the car logically the battery fans would kick in to cool the battery as needed.

No other settings for PIRM needed. Normally leave it enabled all of the time.

It always amused me how Porsche managed to complicate something that has been solved by others before the first Taycan was ever sold. Almost every other EV has it solved so that it's intuitive for customers to use, only Porsche decided to be different. That is not to say other EV's haven't screwed up other UX, but on charging, I think Porsche has the industry's worst charging settings UX, be it somewhat improved in J1.2 Taycans (from what I read).

I don’t believe the battery would heat up so much in 3 km’s of 50km/h roads.
On top of that. When I arrived home the nav was still redirecting me to the DC station so it should have been preconditioned in any way.
i’ll keep an eye on it.

Porsche nav is funny. On my 3,500 miles drive home from the dealer picking up my car I used Porsche navigation, so that it would preheat as needed. On one of the legs Porsche nav determined that I didn't have sufficient range to reach the intended DC charger, so it added a stop 6 feet (2m) earlier, at a slower (50kW instead of 350kW I selected), and it made nav all happy showing I will arrive at the 350kW charger with decent reserve - what it wouldn't show me is that I might not make the 50kW charger at all!

 

[CaptainJorg]

When I precondition it on long road trips, it often goes 40+ degrees.
What makes you think it was not preconditioned? If the temp was 12* I would agree. 43 sounds a little high but not unexpected.
