BrydoMotorway driving reduces ev range but how effective is brake regen when driving in the city or on short stop start journeys?

I’ve no experience of it myself but I think it’s pretty proven tech from F1 down?
I also like the one pedal driving possibilities that the various reviewers talk about when it’s on its highest setting.

CarlI have test driven several electric vehicles and the brake regen has been outstanding on all, I particularly liked the soul eV with different grades of regen that you could change during the drive.

BrydoIt takes driving down to one pedal like driving a dogem car ??
January 9, 2021 at 9:54 am #135296When i test drove the soul i loved it on max setting, you could quite easily drive with one foot and holding the left paddle holds the car on a hill similar to hill hold which the car also has but annoyingly you have to enable each time you start it. So really you only need one foot for go 🙂

January 9, 2021 at 12:05 pm #135318My brake regen doesn’t work at all when the SoC is 100% which is disconcerting, but after a few miles it comes in & works just like engine braking on an ICE car.
There’s also a “B” setting which is what you’d use for lots of town driving, the regen is pretty harsh & gets close to “one pedal” but not quite.
It’s also possible to turn off regen completely whilst decending long motorway hills & no-regen in neutral is kinda terrifying. Remember that it’s not a real neutral, the motor is still turning but with next to no magnetic resistance at all.
So, I drive it in the drive mode all the time & it regens as if it was engine braking. Putting the foot on the brake increases the regen level dramatically, and if you really jump on the brakes it does eventually engage the brake discs.
Regen is efficient enough in drive & if you want it much harsher in town you can use “B” mode, it does use upto about 50kW of regen power from what I can tell (vs 100kW of accelerating power). Going down a long hill does affect the miles/kWh figures noticably.
January 9, 2021 at 12:27 pm #135325Ours being a PHEV the SOC needs to be below 80% before the energy regeneration engages, once the SOC is below 50% the regeneration is more efficient. In standard D mode it is set at B2, you can manually adjust it use the paddle shift to B0 or up to B5. On a PHEV which ever B mode you use it just adjust the throttle position, not sure if it the same on an EV.
We just leave our in B5 it saves me using the brakes, I have now got it down to an art, previously the missus was complaining I was stopping a bit short.
I have to admit I am guilty of being obsessed with energy recovery.

Clipped wingsStarter/ generators ie motor/generators have been around on aircraft for many decades. The variable generator energy input control introduced for electric cars. Yet to drive one but see the Tiguan start stop now has an element of regeneration. See the vw iD3/4 have rear drum brakes so regeneration energy transfer must be highly effective.
