I think I'm still slightly confused...bear with me...I'm new at this...this should clarify it...but on an EV, you always use regen to bleed off speed before friction brakes, because to do otherwise is simply daft.
Now I think about it, this explains something. A few days ago I was sat with the car parked on my drive trying out various features/controls/options as I read through the manual and when I came to the regen part of the manual I drove the car around the garden (possibly at about 10mph) trying out the regen and it seemed quite odd to me that there seemed to be no distinguishable difference between even positions 0 and 3, it was like the regen just did nothing. I tried it out today at different speeds (30-45mph mostly) and the different between 0 and 3 is quite a lot. 3 is really like pressing on the brake.Because you can't use regen at very low speed, friction brakes are mixed with regen as speed decreases, with purely friction below a certain speed, somewhere below 10mph. Doing an emergency type stop varies between cars. Some go max regen and friction, but making abs work properly when you have a motor also braking is hard so below a certain speed, it'll be friction only.
I think all modern cars can exceed 20kW regen capacity, which is equivalent to quite aggressive braking. This can lead to a situation where brakes discs end up corroding due to no wear. Something manufacturers are presumably trying to address. See the MG comment above!
Thanks. The screen you are showing in the jpeg, does that correspond to this one in the centre of the car where the radio controls are? This is a photo I just took of my car. What buttons should I press or what should I do starting from the below picture in order to find "EV" , the first thing I need to find to follow those instructions?
You need to go to the settings page for 3 driving modes and it should be there.

If you are slowing down and the road is uneven, if the wheels start bouncing then the car may switch from regen to disc. Potholes will do it.When is regen is 0, you can press the brake pedal quite hard and it still regenerating. @Ralkbirdy when you say "the brakes will jump to discs especially on regen 0", can you define that a little more? If slowing down gracefully, I can't see why the disc brakes would be used much, if ever?
On my photo you have the home page with navigation map and EV icon, also under those buttons is a separate EV button at the bottom of the picture, this is mk1 28kW version.What buttons should I press or what should I do starting from the below picture in order to find "EV" , the first thing I need to find to follow those instructions?
