2014 Smart ForTwo Electric Drive won't charge

the car is not charging there’s a mulfunction noted on the display my battery shows totaly drained on the display wish someone give me solution on this issue

These things sold in such low numbers finding someone else who has one is really going to be difficult. All you can do is call Mercedes dealers and see if they have a clue . Also there might be Smart Car forums out there on the web. Even a large golf cart dealership might be worth a call .
If you get it running I say sell it while you can because they have pulled out of the US market if that is where you are.

Due to the rarity of these cars, I suspect you will have to take it to the dealer.
