Happy to try things. The more we dig at one point I would hope that it leads to a solution for us all.
Wonder if the before update behavior is the same.
I don't think this blows your theory. In fact, my bet is that you are essentially correct, meaning that the reason for whatever change was made with this update was to protect the OBC or some other aspect of the charging system, meaning to restrict the total power going to the car. In that case, it wasn't exactly a mistake, but the effect was more subtle than anticipated. One would think it would be possible for the car to check the voltage, and then limit the amperage to suit, but maybe that's too complicated. It's conceivable, as you implied, that there is an interaction between voltage detection and ambient or battery temperature also which would make the effect that much more difficult to diagnose. Nevertheless, someone wrote the code to do this and presumably it was reviewed and tested. It's conceivable that the testing phase was not comprehensive enough.
you are too kind and I agree with your analysis - and you hit the nail on the head and a line of reasoning I was thinking about anyways…
How low are you dropping the voltage and which regulator did you go with. I am able to get this to work 100% of the time
I’ve dropped it to as low as possible before getting the low voltage error on the charger. I believe it’s right around 80. I’m using the Vevor auto variable transformer, linked above.
They were telling me they needed to rule out external influences for a while. I had an electrician come to my home, I had my hydro provider come to my home and they installed a transformer to lower voltage coming into my home as well, and other cars are able to charge at my home as well. It's just my car that can't charge. I also can't charge at my neighbour's house who also owns a Taycan. For me I haven't been able to charge for 3 months now. You're lucky you have a lemon law where you are, because I think consumers in Canada are shit out of luck. I don't know what type of leverage I have to get them to replace my vehicle with a different one that won't crap out on me with a software update.
I'm being told my ticket is already with Germany and it's on high priority. But even so, I am still waiting for a fix.
My dealership hinted that there will loss on both sides. Which means, they're not going to just replace the car for you at no cost. What they'll do is basically take your car back at market value, and sell you another vehicle, which to me is unacceptable. Because I wouldn't have to think about changing cars so soon, and that's an extra expense I wasn't planning on taking on so soon. My guess is I will either have to suck it up and live with this, or cash out and never buy Porsche again.
I purchased a Grizzl-E mini connect charger which allows me to change the current limit in Amps by using their app (Highest 40a/Lowest 7a), and also you can set it manually using the dip switch inside the charger (which would require me to open it up and restrict it). I have tried the app route so far, and no matter how low I set it to, the car still won't charge. I haven't done the manual restriction yet because it's a pain in the ass to do
I'm a tiny lady at 5'2" tall, and my outlet is so high up I need to carry a heavy ladder over from the opposite side of the garage over a couple of steps because my car is in the way.I'm a little confused about how you guys are doing this. The transformer you guys shared uses a 120V 3-prong plug. But the Porsche Mobile Charger is a Nema-14-50 and there's no adapter to change its plug to fit the 120V outlet. So how are you able to plug a charger to your car? maybe I'm missing something here.
