Question on regen …

[ColdCase]

Air

Like in a lightning bolt? Or like a high power radio or radar that will jam everything nearby if not cook pedestrians? Or is there a new physics I'm not aware of.

Perhaps the software simply applies the brakes when you lift the throttle to provide the one pedal feel.

Not sure that's the case. When HV battery has a high state of charge recuperation is (logically) limited and the energy lost as heat. This does not mean that the motors don't provide braking and only under emergency braking would the rotors come into play.

I'll cite the following article in support of my take on this...
Porsche Newsroom article on Powerful latest-generation PSM motors

Here's the relevant quote:

Recuperation offers further efficiency benefits. Recuperation at up to 240 kW (Macan: 200 kW), depending on the level of brake pedal actuation as well as the temperature and state of charge of the battery (SoC), among other factors. This corresponds to a deceleration of around 4.3 m/s², which is about 40 per cent of the maximum braking power. This means that up to 98 per cent of the total braking energy can be recovered, under everyday driving conditions. If the desired deceleration is greater than the power that can be absorbed via recuperation, the hydraulic brakes are applied. The fine balancing of the braking force via the blending function is imperceptible to the driver.

If you think about it, what would be the reason to place wear and tear (excess heat) on the hard-to-repair/replace motors when you can have the brakes (which are designed to be serviced with replaceable parts) do that work?

I don’t think recuperation generates any more heat than torque generation (driving) does. The motor simply functions as a generator.

Precisely - this refers to hard (emergency) braking ) deceleration and not routine braking.

Late to the party on this topic, being as I'm referring to some of the much earlier comments, but for anyone struggling to find the on/off for recuperation, or many of the other settings Porsche has chosen to hide beneath eleventy-twelve layers of menu - just ask the car. I couldn't find the setting in the menu but 'Hey Porsche, turn on/off auto recuperation' did the job. I actually first called it auto regeneration, not recuperation, and that still worked - the car just corrected me lol

Good call! I had assumed Hey Porsche only controlled media/phone/navigation/climate. Now I wonder what else "she" can manage. Cameras? Windows/sunroof/locking? Cruise control settings? Some experimentation is now in order.

I imagine potentially lots of on/off setting options, but perhaps nothing as grand as the sunroof. Let us all know how you get on

There's a list of commands on the Taycan forum but don't expect the earth - no cruise, locking, etc - heating (its cold or too hot in here works), audio / music, / volume contact calling etc generally yes.

I periodically use it but when simple things like "Hey Porsche, what time is it?" results in "I'm sorry, I did not recognise that command" I give up on it (repeated attempts will get a response).

9 / 10 it's quicker to make the request yourself.
