TACC/AP and reduced regen

[MrBadger]

Started a trip today on high level of charge so much reduced regen.

Very noticeable when manually driving the car, but when I went on AP, I got the impression that it was much more lethargic in its braking - based on sample set of 2 AP experiences. Couple of times I thought about braking to override the lethargic speed reduction - almost as if it was using only regen which was greatly reduced.

So how much is TACC/AP affected when regen is low?

I've also noticed regen is limited at not-very-low temperatures, around 13ºc outside temp when the car has been sitting parked/off for 5 hours or so.

Yesterday, I had set charge to 70% overnight. When I set off, I noticed an alert on the screen saying regen was limited. After about 15 mins of driving, I noticed it had disappeared.

Was this because I had a charging limit set and it wouldn't regen until I'd used up some battery? I thought regen would add to my charge if it was under 100% even if I had a charging limit set.

no, it's just because the battery was cold. You get the same if it's warm and > about 95%, but in your case @ 70% it was because it was cold.

So does the reduced regen affect the effectiveness of TACC/AP braking ?

ah right... that'll be it. It wasn't charging prior to me setting off.

Well the car still has actual brakes it can use so probably not?

 

[MrBadger]

This was based on the car feeling a bit lethargic in its braking actions when on AP yesterday. Wondered if it not having access to regen due to its high state of charge was the cause or whether it was just out for a Sunday drive. ie its behaviour differs whether its using regen of brakes to slow down?

Well I doubt that the car would not compensate with use of the real brakes if regen was limited. Perhaps it was using the real brakes hence the difference in how it felt

..or it was letting limited reg do it;s job and waiting on real brakes as backup if needed? Speculation. By the time I get anywhere from home (in the depths of rural) to where its safe to use TACC my car has heated it's battery so i have no way to appreciate,
