My C350e will only charge up to 22kms charge.

I thought it was supposed to go to 31kms.

This means I am losing out on 30% of its electrical capacity.

Has anyone else had these problems?

Your car will give you a range estamation based on historical usage. It is possible to drive 31km with that charge but you have to drive very economical.
I managed 33km once but normally mine also indicates around 22km. So nothing to worry about.

JIMSHANN

What I am saying is that it will not charge enough to show 31kms. It will only fully charge to 22kms.
This means that, actually, I only get a true kilometre usage of around 15kms.

GerritKw

Your battery is still fully charged. You can check that in the center display under travel. Or the center display under your car menu. It still is an estimate.
In winter your mileage is less due to energy required by heating the interior and possibly the chairs.
In summer it will get better though.
But under normal conditions 15 km in winter and 20 km in summer is my average.

JIMSHANN

You have to realise that it is mid summer with temps over 30C in Australia and I still only get a maximum of 15kms, no matter how carefully I drive.

To me it's like having an 80 litre fuel tank and only being able to use 40 litres of the fuel.

Maybe you need more electricity to go into your battery.. try jumper cables

JIMSHANN

I think you are missing the point here. I am talking about the charge of the Hybrid Electric Motor. I doubt that jumper leads would work. It's a 240 volt charging system with very heavy duty cables.

GerritKw

It is clear that the 31km is at optional conditions. It's winter here now and I do about 15km's.
The mileage depends heavily on the weight of your right foot
Did you get any instructions from MB on how to use the plugin?

JIMSHANN

The Mercedes dealer had never sold a C350e before, so, had no idea of the Hybrid details and couldn't give me any more information.

I guess I'll have to visit the MB main dealer in Sydney and ask them.

I've driven the car very carefully just to see what happens. I have driven it, without the petrol motor having to start (i.e. 0 litres/100kms) but I cannot manage more than 15kms.

If I drive an actual 3kms it says I have used 5 kms worth of electricity. I can just accept that, since all the electrics are operating from the Hybrid battery.

However, I still cannot understand why it will only fully charge to 22kms when it should be 31 kms.

GerritKw

When I drove the 33 km i hardly touched the brakes.
Braking recuperates energy, but still it is less efficient than letting the car coast as much as possible. My speed did not pass 60kmh. At higher speeds the electrical engine is less efficient. Also, You probably are using the air-conditioning, which requires more energy.

Sometimes the batter gets low because of the cold weather and can't fully change.. try going to a heated garage

JIMSHANN

I don't need a heated garage!! The temperature is plus 30 Centrigrade!! (90 + Fahrenheit)

I understand and agree with most of the comments.

What I cannot understand is "When the battery is fully charged, it only shows 22km range". Why won't it charge to give me the claimed 31km?

Shadwell

Go to the dealer.......
if they don't know it's their responsibility to find out...

Gungaslow

90deg F!!!! Well there's the problem... it's too hot... maybe it will get better when it cools down a little

GerritKw

The range it shows is an estimate based on your historical usage.
It works exactly the same as the estimated range for the fuel tank.
You can reset this by a reset of the distances in the travel/trip menu. Don't know where exactly.
After that it will show you 31km for one time and then after a couple of trips you are back on 22 again.

JIMSHANN

Sounds daft to me. I'll try to give it a go and see what happens.

ManiacGT

surely this is just the same argument with petrol as it is battery? IE the estimated total driving range is dependent on the way you drive, traffic, weather etc?

JIMSHANN

You may be right. However, from day one I have never been able to get more than an indicated charge of 22kms whereas it's supposed to be 31kms.

30% difference!

GerritKw

If you don't hit the brakes but use coasting and accelerate slowly you can get 31km and more.
Did you ever have the eco meter on 3 times 100%?

Hi guys, I've developed an Android app called EvAccess that is a substitute for the mycclass.mbusa.com or Mercedes Me web site/app. It was originally created for the B-Class Electric Drive and Smart ED, but I've added support for the Mercedes hybrid vehicles as well. I'm looking for some feedback from C-Class owners. You can get is from the Google Play Store, search for EvAccess.

GerritKw

Got it installed and it looks nice.
Still some values (trip data (last and after reset)) are showing 0. Will check this out after my first drive.
It has the capability to set the time for the climate control. Something the Mercedes Me app is lacking, so that looks great.
Missing some other things though. The maintenance info in the Mercedes Me app is more comprehensive and it also shows the locking state of the doors and windows.
I will do some testing and let you know.

jwarcd

Thanks for the feedback!

I've created a new thread to talk about the EvAccess app so I don't interfere with this thread.

i have worst! 100% show 18km, real around 10km..any solutions?

GerritKw

What was the outside temperature when you drive it?
Did you drive in Eco or Comfort mode?
Did you use the pre-conditioning function?
The heating of the car consumes a lot of energy. With a normal combustion engine the heating is fine with waste heat of the engine.
My electrical driving range varies a lot at some cases. today i had a cold day and i did 2 short trips of 4 km. It had to heat the car twice. I was at 30% when i got home.
The temperature of the batteries have a big influence also. I therefore try to charge the car before i leave. The temperature is a bit higher then because of the charging. All tiny bits help.

i stay in penang, malaysia, temperature 26-33°, both eco and comfort mode, same result, full charge at 18km, actual around 10km.. feeling depress
