Regenerative Braking Reduced

[SoMa]

Regenerative Breaking on my Model Y (2021) has significantly reduced sine fall of year. I right it was the cold weather in the northeast. As the weather recently warmed up, the performance is still low. I AM using my brake most of the time while driving around town.

Any help would be greatly appreciated. Thanks

Cold temperature. It will take more than around the town driving to warm up the battery to get the full Regan performant

I would be curious to see if the battery state of charge display contains a blue stripe and a snow ice flake icon
when you encounter such reduced regenerative breaking?

What's your definition of "warm"?
If it's still less than 60 degrees F, then your battery is still too cold for full regen.

I live on a hill, and have reduced regen when it's less than 60 degrees. It's much better when you use scheduled departure.

I should had mentionned in my previous posting #3,
I suspect it was around 50 F (10 C).

I parked in a garage, near San Francisco, and it was around 5 am.
Next time I will check the ambiant temperature.

Its normal as others have said. You need sustained periods of temps >70F and a state of charge of 85% or below for full regent at the start.

Keep in mind the battery has a lot of mass and can take considerable time to warm up after it has been cold-soaked overnight or for a period of days.

It's very difficult to determine why your regen 'breaking' is lessened with knowing where you live, what your typical SOC is when you experience it, whether or not you precondition prior to driving, etc.
