I'Ve noticed a green Charge Display Bar in the dashboard when viewing the instantaneous fuel consumption gauge.

Does the car recharge the car's battery when coasting?

 

what does the manual say about this?

 

Nothing ... I'll also try asking in the benzworld.org forum.

 

Yes please, I keep meaning to ask this question myself

 

I found it once, now can't find it again. It has something to do with the electrical system recharging from braking. If you brake, some charge goes into the battery rather than from the alternator. You'll see that bar fill in when you brake.

 

 

Thanks !!

I guess coasting recharges the car's regular battery, then, since it's not a hybrid.

I wonder how this works ...

 

I guess they are looking to put less strain on alternator thus reducing gas although this is probably so insignificant but who knows.

 

When I first say it, I just assumed its for the plug in Hybrid when it comes out next year.


The Eco circular graphic gives you bonus range which is sort of interesting. You can earn in any Agility mode

 

bmw has been doing this for a few years now. Indeed it just reduces the strain on the alternator, which thus reduces gas consumption

 

I saw a testdrive/review on Youtube for the Active Tourer where they mention this...I think they quoted a reduction of 3% in fuel consumption thanks to this.

 

Not accidentally raising this thread from the depths, I just googled this display indicator (have been meaning to since last March) and wanted to say thanks for posting the information. Now I know one more thing about my car.

 

I asked the service department about this display when I first got the vehicle. They had no idea.

 

It is in the manual, where it describes On-board computer and Displays; Menus and Sub-menus(p.244).
"Recuperation display = shows you if energy has been recuperated from the kinetic energy in overrun mode(see Eco mode description) and saved in the battery."

 

This charging get green when you lift the throttle. It will then charge the AGM battery. The AGM battery is only 80%-85% fully charged because the rest is needed for the kinetic energy.

 

It helps charge the secondary battery which runs the stop/start system.

 

At least in a C 200 model there is only one battery which is 60Ah.
The AGM battery is developed for start/stop system.

 

Sorry, but all W205 have nly 1 battery right ? The auxiliary battery has been changed for a big capacitor ?

 

Yes. (Probably a set of capacitors.)

 

It's regenerative braking. When you let off the gas the alternator goes to full charge, which will slow the engine and make you decelerate faster while charging the battery. It's a fuel conservation measure.

 

Is the bar supposed to build up to show u how much u have charges or just a guide?
