I noticed at on my 320i's dashboard there is this battery logo (see pictures below) when the engine is on, I often assume that it just means my battery status is OK.

I also noticed that when driving and I am not accelerating and breaking, sometimes that battery logo will be gone and a small car logo with the same blue colour (just below that number '90') will be shown, and as soon as I break/accelerate it will disappear.

Is this the 'regenerate breaking' people were talking about? I simply can't find anything Driver's guide (app) regarding neither of these indicators.
