US people and Canadians are all (North) Americans and friends too, but it doesn't mean they have identical car regulations.

They make exceptions all the time, check out North American cars, or even US vs. Canadian cars. Some of those are not even just software (e.g. Canadian vs. US seatbelt latches).

Or the UK regulators just think the same as EU regulators, or perhaps just using a lazy approach - copy someone else's work and still get paid. I guess EU regulators have not thought to copyright their regulations. We have a state here in the US which copyrights its own laws, so if you want to...

OP is in the UK, no EU overlords dictating car features (including which side of the road to drive on, or which seat should have the steering wheel ;)). This must be the local UK regulations.

I wasn't suggesting using timers on DC, just DC charge while battery still hot, then park at your hotel, set a timer to preheat the car in the morning (from battery), then drive to DC charger to top off if you need max range. If you set a departure time, it will start early enough to preheat -...

The main mitigation for cold weather EV driving is to plan ahead and preheat your car and its battery from shore power prior to departure. Shore power can either be AC EVSE or DC charger. That's what departure timers are for. This will extend your range as the car starts with an already warm...

Perhaps reach out to YouTubers/reviewers to get some more exposure to it, they even be able to get an official response from Porsche.

Good luck! I am genuinely curious how far you can get with this with PCNA.

It might seem like just a red herring, but consider thisL a 3 phase connected EU Taycan with an upgraded onboard charger can charge at 22kW, but in NA on a single phase only 19.2KW. 2.8kW difference between EU and NA, on a 22kW the difference you are seeing is exactly half (11kW-9.6kW = 1.4kW)...

If that someone is the guy who sized the charge port wiring for NA cars, it's not easily fixable.

That is what's going to be your biggest obstacle. Most of Porsches support/service chain has very little understanding of EV charging. Add to that the many engineering silos and suppliers involved in each Porsche design and marketing, and you'll have a hard time even tracking down who set the...

Hardwired is usually cheaper (proper NEMA 14-50 is ~$80+tx), so you probably saved money. AWG6 wiring it typically used to both 50A and 60A circuits (for most length installs in a conduit it's actually rated for slightly above 60A). The only way this costed you a little more is if the breakers...

Perhaps they'll remind you that you they sold you your Taycan with 9.6kW advertised maximum, but the Taycan was able to charge at 11kW. Now they sold you one that advertised 11kW but only charges 9.6kW. Maybe they'll call it even? :CWL:

What you describe is called a "split phase". US households get a single phase 240V, but with a transformer mid tap to allow you so split it into two 120V, 180 degrees out of phase, split phases. 80% limit comes from electrical safety code, it applies to any sustained load (including the...

It's not a matter of maybe, they have to put a different harness for NA Macans purely because the charging port has less pins in the NA than the rest of the world. There is no way (for a typical user) to connect 3 phase to a NA Macan - no pins in the charge port. There are some CCS1 chargers...

It might be a setting, assuming the onboard charger is programmable (remember how enabling PnC required replacing the entire onboard charger on Taycans?). Furthermore however, remember that >9.6KW in Europe is only achievable with 3 phase AC connection. This means there are no single phase wires...

The 40.7A was shown on Dave's Porsche EVSE, so it was end-to-end Porsche environment, meaning we're dealing with some sort of German precision example (either measuring or actually consuming). Perhaps they need some Swiss watchmakers on their team to improve their precision? ;)

Could be all new V4 cabinets. V4 is supposed to have the Magic Dock as standard equipment.

It would be easier to hook it up to OpenEVSE and sweep the pilot duty cycle while measuring current and voltage and noting the car's power display. How much time you got, or how determined are you? ;)

I looked a little deeper, it might be possible, or it might just drop to the next lowest, so might signal 40A. Below is a slide from this slide deck (which by the way is a good overview of the J1772 signaling). It shows discrete steps for the duty cycle. What is unclear however, is whether the...
