Preconditioning & charging planner

[sor]

Yeah, that I think is the source of the info people are quoting about a rebalance procedure. The document itself doesn't imply it's a self-service way to rebalance, but at least mentions that it can occur.

1. drain
2. let sit awhile (6.5 hrs), and it even states a rebalance can occur at low SoC
3.charge completely
4. let sit again

Yes, you absolutely can set a charging station as a destination. You can do that in the Navigation system as well.

Hi to All

Yes.

I do the same if / when I use the Porsche route planning app in the dashboard.

Provides route plan just like Google Maps, Waze, etc. but it also shows charge estimates at arrival at the charging venue and begins to pre heat the car battery (which of course consumes charge on the one hand but protects the battery from heat stress experienced when charging at a fast charging statio).

Yes. Doesn’t select the actual charger at destination charging venue as these are occupied or free based on actual traffic / other EV owners using location.

Nonetheless it works as expected noting that choosing a fast charging venue close to where we are located means the car battery won’t easily “preheat” to degrees (C/F) ideally targeted if the distance is near by.

When I travel 120 miles between two residences, the vehicle systems have plenty of time to warm up my battery. Otherwise short hops make time to heat too short.

Better than nothing though.

Had my usual business trip of 600 kms on highways with stops for fast charging along the way on Ionity 350kw chargers.

1) 10,5C outside, battery temp 16C after driving for 30 mins at 150kmh
2) battery temp started climbing to 26C about 20 mins before reaching the charger
3) at the charger (but before plugging in) the battery was at 34C and was at the upper range of optimal window - strange, there should be no need to go that high with preconditioning
4) charging started at 41% SoC and reached the peak of 188kw after one minute - strange, should be well over 200kw
5) the charging speed quickly started slowing down to 167kw at 56% SoC and went downhill from that - strange, the charging curve looked degraded due to battery temp as no fans were working
6) at the end I left the charger with 80% SoC and battery temp of 45C and ONLY THEN fans started working at full speed to cool the battery (after I disconnected the car from charging, they were silent during charging process)

This shows the software controlling this process is buggy and was not able to precondition the battery for maximum charging speed. The charger was empty, should easily provide 350kw.

Looks like:

1) it overheated the battery a bit during preconditioning
2) it did not run fans to cool down the battery during charging process which degraded charging speed
3) after disconnecting it engaged fans at full speed like trying to compensate for lack of cooling before

This is what I always get when I start charging at SoC higher than 20-30%. If this is the case I think given 3-4 charging sessions a week like this, the battery will start to degrade. Good it will not be my problem then

You can look at all the data below.

OMG that is rather bad.

Today I was at IONITY for the first time with my Porsche as I wanted to add a payment method, and the only way to do this is at the charger, only then you can add credit card …
Anyway that failed as plug and charge is active on my car and I did not even new that, I never set that one up, so it seems that was auto activated or I did activate it myself and never tested it and forgot about it.

Anyway I was at a to high charge at 50% but I never saw the 200kw … it was 130 as the battery was only 17C and reached 73% after 13 minutes and like 25C … 23% added

I hope the touch screens work as I needed to push start the second time I tried it as I was confused why the car started charging the first time (did not need to push start the first try)

So to add a payment method next time I will not connect the car …

Or can someone confirm I can use the Porsche app to scan the QR code to start the charging at IONITY?

Yes you can do that. I didn't try the QR code but did manage to start charging using the app (you go to nav -> chargers -> select charger -> select slot/port and there is an option to start charging).

Cool thanks, the reason I ask is that sometimes the touchscreens hang, but you can start charging via the App, good to know that you can start it via the Porsche app if for some reason the start button on the charger is not responsive ...

Just a sanity check will the charging with plug and charge start automatically? (as mentioned the first go I did not need to press start, but second time yes.)
