This is not a battery temperature or state of charge issue. Those possible affects have been eliminated in discovering this.
A number of model 3 owners have found that once they’ve installed winter tires, the regenerative braking has disappeared at higher speeds. It only kicks in at about 30km/h. Prior to that, manually braking is required.
IF this problem has affected you, and you have ruled out a cold battery or too high of a charge, would you post the winter tires you went with and rims. Also, if anyone with a model S or X has this issue, please post too. I’ve only read it affecting the model 3 and have seen it first hand with replika rims and continental SIs. I have read others have it with OEM rims, Xice and the Nokians.
Here is a post form someone that went to Tesla about it:
Just got my Model 3 RWD back from TESLA Service Center. Had literally no Regen...akin to coasting...had to use breaks all the time. The TESLA Technician and I , both sent info in “Technical Bulletin” form of why I had practically zero Regen.
Just before we (GTA area, Ontario) got an unusual hot spell (28C temp), I had swapped rims ‘n tires from “All Season” to “Winters”. Continental Winter ContactPro SI Tires, to be exact. These tires are rated highly for roadhandling, ice and snow traction and really short stopping distances.
After exhaustive tests by TESLA Tech, it was decided to switch back to All Season Tires and Regen test again.
Hey Presto, back came full Regen. So in a nutshell, the winter tires composition I.e. higher content of silicone to keep rubber pliable and not stiff in cold temperatures, makes the same composition advantage, a disadvantage if you drive in warmer weather....too much stiction affecting a Regen module sensitivity.
So, for all us Canadians that drive down south at winter onset, we’ll have practically zero Regen, once we hit Alabama/Georgia and on the way back, get full Regen once in Illinois, Ohio and Michigan...or whatever states you drive through, that are in the northern hemisphere.
Cheaper winter tires with poorer roadholding, will tend to give you better Regen but less safer driving.
Let’s see how widespread this is and whether Tesla can do something about it.
