I'm not fully familiar with UK options, but as far as the 0GBP cables that I see in the UK configurator, that depends on what the plug in the wall in your home looks like. I don't see the Porsche Mobile Charger Connect is an option anymore in UK (believe there is a stop sale), but you shouldn't get it either way. Very expensive and doesn't provide any additional charging speed or functionality vs. the free charger cable. Also has some issues with overheatingThat’s an interesting post Whan, thanks. To clarify, are you saying that the cabling options are a waste of money? I’m based in the U.K. where we don’t have many super fast chargers and the Porsche cabling options are very expensive.
The "On-board" charger and converters are not cabling, they are modules inside the car that allow for additional charging capability. One is for fast charging at 400V stations (That is the 150kw DC-DC converter), and the other is for increased charging rates at home (22kw on-board charger). In UK and Europe, I've heard there are far more 400V charging stations than in the US. Also Tesla has opened up their network in much of Europe to non-Teslas. I would get this option, living in the UK. It is also not that expensive at only 294GBP
The 22kw on-board charger is only useful if your house/residence can provide 22kw. It allows your Taycan to receive charge at max rate of 22kw, vs. the standard 11kw. With the usable large battery being 83.7kwh, it takes ~4hrs to charge from 0-100% at 22kw (83.7/22) and ~8hrs at 11kw (83.7/11).
In the US, the common appliance outlet that is also used for EV charging is typically 240V and 50Amps, which is 12kw (240*50, kw = Volts*amps) maximum (in practice usually only 40Amps for safety, so 9.6kw). In this circumstance, increasing the home charging cap from 11kw to 22kw is useless since the house can't provide much above 11kw anyhow. I know in the US in order to add capability to 22kw, there is significant infrastructure work needed, and for many homes it's not even possible as it's constrained by the power lines. I have heard in Europe it is more common / more possible, but still perhaps uncommon.
In general I think the 22kw charging isn't that useful anyhow. The use case is pretty limited. The scenarios of you driving 250-300 miles in a day (6-8 hours), using all the battery, then returning home and needing to charge as fast as possible to head back out, are minimal. Most people will fully charge at night, so there will already be 8 hours of charging time available just from that.
