Max Charge in Consumption Display

I recently bought a 2017 W213 4Matic. Really enjoy it.

I have a question about the Consumption Display. (See photo). Even though my car is not a hybrid, the display has a "Max Charge" indicator. It turns green when I'm decelerating. What does it really mean in a non-hybrid car?

Perhaps it is regenerative braking. I don't have that element the consumption display on my W213.

I have it on my GLE and someone once addressed in that forum. I don’t remember what it was, but maybe if we look in the W166 forum it will tell us.

I have been trying to figure this out myself since I bought my car. It is not in the manual... The closest I have come to understand is that it shows the charge of the ECO start/stop auxiliary battery level (needs to be >80% charge). Hopefully someone can correct me if this is not the case.

At least in my 2018 E400, and I think all current vehicles (with exception of the new inline 6 with 48 volt battery); there is only one 12 V battery; there's no special power source for ECO start/stop, and no separate auxiliary battery as found in older MBs. The bar graph you see is indicating 'mild regenerative braking' being used to charge main battery. BMW also introduced this a few years ago. I'm not sure if they recover energy from the braking system, or more likely somehow switch the alternator so that more power is sent to the battery. The bar regularly switches to full green when I take my foot of the gas pedal and the car starts to decelerate; it does not come on when I decelerate gently at a low speed using the brakes.

No Batteries anymore it was replaced with a Capacitor which is a good thing.

The power of the generator is ramped up in rolling phases and in phases of the engine brake in order to charge the battery. In return, the power of the generator is reduced when engine power is used to relieve the load on the engine. This specific form of battery management requires AGM batteries (which the 213 has) to cope with these currents.

So coming back to the original question about the gauge... How is this quantified and represented on the meter? Mine appears to be always green and full.

Thanks.

It will show green if you decelerate (extra generator power) and it will show nothing if you accelerate or maintain speed with normal gas.But it is a very rough indication.

I have a GLE350 with no ECO. I have the "charge" indicator in the MFD. So the charge indicator is not strictly related to ECO function. I am interested in the answer to the OP's question.

It has nothing to do with ECO or fuel consumption. It's just an indicator that lights up green when the battery is charged to the max.
