[North American] - my feedback for enhancements with future software…

[daveo4EV]

I provided the following feedback to my dealer and Porsche customer feedback:

Team,

Having completed a 2675 miles road trip I wish to congratulate you and Porsche on the release of a stunning vehicle - I’m deeply impressed with the product and pleased with the purchase. The feedback below may seem trivial but it is a serious request and I sincerely hope we can get this in front of the proper people at Porsche in the hopes for a future software update…I know you can not promise and I can not demand update, but please serious consider it and do your best.

Two requests:

#1 and most important in my mind : the minimum charge behavior when the vehicle is plugged in must have an option to abide by and respect the optimized charging schedule - the feature as currently implemented forces me to charge my vehicle at peak rates…which is costly/frustrating - I am requesting any adjustment to this feature - lower the minimum charged to 15% instead of 25% or allow me to not have minimum charge because of peak billing rates…any sort of accommodation to this feature will be an improvement because it costs me actual money to plug in if I’m below 25% - and this is very very frustrating…

#2 - the new AR HUD is a fantastic option - and the integration with the Porsche Navigation system is excellent and fantastic - one of the greatest feature of the Porsche navigation in the Macan is the vehicle’s navigation can estimate battery % at destination - so I put in that I’m driving to Steven’s creek porsche - I’m at 80% battery - and the PCM navigation reports that the estimate is 67% battery when I arrive - this is a _FANTASTIC_ feature and critical planning tool for the 2,675 mile road trip I just completed…my request is that this specific piece if information be mirrored in to the AR HUD!! It would be an excellent driving aid to have the % battery @ destination in the AR HUD along with the other excellent navigation information.

So two requests:

#1 - minimum charge behavior needs to respect the optimized charging schedule
#2 - PCM Navigation battery estimate displayed in the HUD

If I could _ONLY_ have one thing for Christmas/future software update #1 is most important - cause it costs me actual money when I plug in my Macan - and this adds up to a lot of money over time

The long and gory analysis of the monetary cost of the “minimum” charging feature is noted below

Thank you in advance - I know _IF_ any of these requests were to happen it would take some time and a software update that may never come - but I'd really really really like these two requests and I believe so would other Macan Customers…

Gory Gory Gory details and analysis of the actual “cost” of the minimum charge feature as currently implemented!!

First feedback and the most important - because it’s costing me actual money and it’s a pain in the ass…

As noted in the Manual for the Macan EV




As soon as the Vehicle is plugged in at home - it charges to 25% - the owner has _NO CONTROL_ over this behavior other than to not plug in!!!

This is awkward, frustrating and costly!!

My California Pacific gas and electric EV rate plan charges a signification premium for mid-peak and peak rates - https://www.pge.com/en/account/rate...-rate-plan/electric-vehicles.html#ev2adetails






Coming home at 6 pm plugging in and going into my house - if the Macan is below 25% it will start to charge immediately - let’s say I come home at 12% battery - charging to 25% is approximately 13% - 13% of 95 kWh is 12.35 kW - let’s call it 13 kWh

To charge to 25% will require 13 kwh + charging overhead - so 15 kWh on my electrical meter for the vehicle at peak rates is $9.60 to top the vehicle up to 25% vs. waiting for off-peak rates of $4.65 - so this little feature of 25% minimum charge is costing me $5.25 to plug in and walk away

If this happens twice a week for 52 weeks/year - that’s an incremental cost of $546 annually - or $3,276 over a 6 year ownership period.

Request (demand) #1: please advise Porsche I need/require the minimum charge rate to respect the optimized charging schedule!!! It’s costing me actual money because of this frustrating feature!

My $.02 on this is the idea of the minimum immediate charge is not a bad one; it's just that 25% is arbitrary (as would 15% be, for that matter). IMHO this should just be a user-defined setting (i.e. you can set the minimum for yourself).

 

[daveo4EV]

my guess is it's bad to let the battery sit too long at too low a percentage - I get that and if true I would "accept" a minimum charge

but the question here is "what is too long" below a minimum…I doubt less than 24 hours is "too long"

I don't care that's it 25% - I care that is can't even wait less than 24 hour to rectify the "problem"

leave it at 25% - and ok - if it's not going to charge "on it own" in the next 72 hours - charge to the minimum value - but if I plug in at 6:27 pm when I get home from work, could you maybe wait until 11 pm the same day when rates are lower to charge…

there has got to be some way to address this…but charging at $0.64/kWh is simply not my goal.

This is a known flaw in the Taycan charging setup protocol as well. Blows my mind that they still have not learned from the current owners that this is bad design and just carried it over to Macan EV. I do not see them fixing it, since they have not already.

I am lucky I have a fixed rate of 12 cents per kWh so that does not impact me but if I would be paying 64 cents which is more than public charging here, I may have to get up in the middle of the night to plug in when rates are cheaper, because this is just wrong.

That would be nice, but still not allowing to simply tell the car to only charge during off peak time frame is ridiculous.
