Auto Regen vs Off

[Fletch]

I’m surprised how much i like auto regen. I love coasting but it’s nice that it knows not to just coast right up to the car in front of you. All in all it’s smart enough to behave exactly as you would expect it to, especially if you watch the little triangle on the left ‘tube’.

I could be wrong but it seems to me that the savings on brake replacement would be for more significant than the savings in kWh.

Unless you are breaking relatively hard, you might be on 100% regen and 0% brake pads. Which has gotten me used to a very un-Porsche like driving of braking early and not too strongLy.

When I was in Germany, I thought Auto-Regen was very effective automatically looking ahead whilst on the Autobahn.

It's my understanding that when it comes to coasting, auto regen (recuperation) = off mode - auto braking (with the help of inno drive and/or radar cruise control).

Up till internal braking is applied (by inno or radar cruise), auto mode coasts as same is off mode.

When it comes to braking and turning (convert) that kinetic energy into electrical energy, I prefer auto. System is optimized to recoup energy without applying mechanical braking . The moment mechanical braking is used , kinetic energy to then converted to friction / heat.

Auto can be unreliable due to various external dependencies - was flakey before uPdate but seems better post uPdate.

Marginal recuperation gains with what is overrun recuperation. More energy recuperated when using the brake pedal.

If I use it I prefer manual recuperation especially around town.

Mechanical braking energy doesn't get converted to electrical. Rather lost as friction/heat

I just switch it to 'auto' as soon as I get in the car, using the steering wheel button.

I have just got used to it now, especially auto braking when traffic slows.

Mine only allows on and off from steering wheel control.

Is yours 4s?

If you hold press the button for ~2s, it will go to auto.

?? Thank you ! Very useful

Eh no,.not on a Taycan. 95% braking is via the electric motors + I'm 2 years in and know how this works....

Mechanical (hydraulic) braking always uses friction regardless Taycan or not. My point being, when a driver takes control on braking (not leaving to Taycan's system to decide and apply), and when apply in tradition way, aka full braking , sudden braking etc, it must use friction to slow down or stop the vehicle (electric motor acts as generator won't be sufficient). In such cases, recuperation is not achieved. And recuperation has been in engineering fields for many years. Electric trains does the same.

Brake recuperation is the predominant force for adding energy back into the battery (this is always available shortly after start up) and is preferable to overrun recuperation (analogous to lifting your foot off the throttle in and ICE vehicle without applying the brakes) when this has been user enabled (manual or auto).

The motors perform much of the braking force to the extent that in most driving scenarios the brake discs and pads are rarely used.

The most telling aspect of this (apart from the obvious lack of feeling the pads and discs whilst depressing the brake pedal) is the significant lack of brake dust collecting on the wheels rims and brake calipers (I have standard brakes and so this is very obvious).

I've recently had the uPdate applied to my MY21 car and for 2.5 weeks (a few hundred miles) no brake recuperation was available whilst the re-learning took place (same scenario when car is first new). It was obvious this was occurring and could be felt through the brake pedal as well as being audible not to mention the noticeable collection of brake dust as per an ICE vehicle.

In emergency braking situations the discs and pads most definitely come into play.

After uPdate , no change for my 21CT:1,2 miles slightly descending (not 2,6 weeks…) before recuperation works …

More generally,the discs pad are active only if deceleration is stronger than 0,4 g An Extremely Detailed Look At The Porsche Taycan's Engineering Designed To Take On Tesla (jalopnik.com)
