6 7 Cummins Battery Saver Mode

2017 ram 2500 6.7 Cummins
What is battery saver mode ?

Battery saver mode started coming on when the temps outside started getting below freezing.
My older cummins and other diesel trucks didn't have this on it and I'm looking to find an answer and see if something is going bad or if this is a normal process for these newer trucks.
Any info is helpful.
