B-Class Electric Drive
C-Class Hybrid EvAccess App

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.

C350e
Not fully functional

Hi,

After my first trip i am still not able to see the electrical consumption of the car. Also the screen showing how economical i drove is not available.
In the main page i can see the status of battery and fuel tank but the charging power is way to low. Our charger should charge with 230V 16A which is about 3.7KW but it shows only 1.4KW.
The estimated time when the battery is full is equal to the current time instead.
Looks like you either get no access to all the data of the C350e or some fixes are required.
I am happy to help you with fixing this.
Below screenshots with the missing/faulthy data.


I hope this helps.

I'm not sure why the electrical consumption is not working. The data may be different between the pure electric cars and the hybrids. Do you see this value correctly in the Mercedes Me site?

The charging power is an estimate that is calculated using the estimated charging duration and the battery size. I think I have the wrong battery size for C-Class (4.4kWh). The correct size should be 6.2kWh?

C350e
The new version (v5.11) is working correctly now.
I see the usage of the fuel correctly now.
Also the charging power looks OK now on my C350e.
Keep up the good work.
