Limited regen going downhill

[PeterOT]

I tested this yesterday on slopes down hill from Big Bear. Starting at 68% soc, i set charge limit at 60%. First part down hill has actually quite a bit of up hill so soc reached 63% but all the way back down (some 25mi later) i had 70% in thr tank. So the notion that regen wont go past the charge limit setting seems incorrect.

Temps were around 45F when i started down hill and after 20m of driving regen limited light came on (outside was then 40F). Added a super charger destination to the nav to have batts conditioned/warmed up so regen would be restored. I Heard the conditioning starting and had that going on for 10m or so. Regen lim light stayed on and regen indeed felt soft. So the idea that overcoming the regen limit on with temporarily adding a charging desitination seems debunked also. Regen limited on changed on its own much later on the flats with env temp around 57.

Even with regen limited on, the truck was recharging the batteries though i can’t tell if that was at a limited level or not.

Thanks for doing this. This is exactly what I was experiencing. This seems to only happen with the Cybertruck (in my experience) and not any of my other Teslas. I'm hoping a future software update will cure this behavior.

I've never tested that before. So you are saying that if I charge my vehicle to 80%, and then put the charge down to 50%, head off down a steep hill, I will not have any regen? I can't imagine the software is set like that, but I have never tried to test it.

All the times in the Cybertruck when I have experienced this (not expected) lack of regen, I've been at a SOC well below whatever my set charge limit is.

It will regen. What you said I have also done. Charged up to say 70% and know I will be below 50% when I get home. So before I leave after I have unplugged I change it to 50% max SoC so I don’t have to mess with it when I get home. It will regen just fine no matter the max charge limit setting.

That is what I assumed, but good to hear that you have confirmed it with real world driving.

I have noticed that the Cybertruck does kick in the regen limit action sooner than your 2020 X on the same downhill sections that I have driven both on mean times. In my case it is the AWD. I wonder if the Beast is different.
