Re-Gen Braking Charge Lower in Cold Weather?

[gmcjetpilot]

Never noticed but usually in "B" mode I get all FOUR green CHARGE Indication. Now in cold weather I am getting only 2 lights? Braking also seems less, mild. 2015 SV w/ less than 40K. My battery has 10 bars capacity.

Is this normal

In cold weather, yes.

Internal resistance of the battery is higher when the battery is cold, so less regeneration is allowed to avoid cell overvoltage. I first noticed it with my 2011 in December 2012 after dropping to 10 capacity bars. I noticed it with the 2015 in "winter" here in Phoenix after it dropped to 10 bars. In both cases, regeneration returned to normal when weather warmed up.
