Regeneration is limited please use the brake pedal.m

[Peacsy]

1st Gen ZS EV which has 5 year service last week, they mentioned slight rusting on the brakes so turned kers down to 1 and tried to give them a little clean.

However since then and turning back up to 3 I've noticed when I start the car I get the "Regeneration is limited please use the brake pedal" message pop up, even though it feels like it's working once I set off?

Any ideas.

My MG4 does that when the battery is at 100%.

The battery level is around 90% currently, so it's not as if the energy doesn't have anywhere to go.

Our Niro gives the same warning at lower %ages than the MG, maybe its just part of the way the BMS is programmed, or just that at regen 3 it can put in a higher current that the BMS will allow.

It's odd that this has started happening since the service, as I had never experienced it previously, even when the battery was fully charged. Although I have tried balancing the battery since then, so maybe that's something to do with it? (told at service battery health was 90% and they suggested that might help).

Do you know if there's any way to monitor regen when driving?

On the MG4 it shows %age braking effort and the consumption screen 'should' show how much has been returned. Maybe a ZS owner will be able to help.

I think on this screen you will see moving arrows when you are driving, indicating the flow of electricity. Obviously I can't take a pic when I'm driving :-D

If you accelerate you will see the charge going one way, and a positive figure in the power% on the right. If you are in regen 3 and lift off the accelerator, the arrows will reverse direction and you will see a negative value in the power%.
As mentioned already, if the battery is close to 100%, there will be no regeneration. Not sure how much it needs to drop to start regerating, but I believe it does regerate at 90% on my car.
