My 2014 ED stopped taking a charge in June, but we didnt bring it in to the dealership until a week ago or so. They tell me it needs a $6000 battery charger control unit - part N83. Apparently there are no used parts for this and paying $6000 is my only option. Does anyone have any information on this? It seems like a design flaw for the battery charger for an electric car to go bad and to have to pay that much to fix it or else junk the car.

I just moved your thread to this forum which is where it belongs. Lots of info on battery problems similar to yours. Not a good situation, but do some reading of owners who have experienced the same problem. Good luck. Keep us in the loop and ask questions as they come up.

Recently an ED owner responded to this problem by getting a salvage charger unit, installing it himself and reported here that it works.

$6k will go a long way today toward purchase of a Chevy Spark_EV in good condition. Similarly if your battery was the culprit that $12,600 would buy a beautiful condition BMW i3 which is on Craigs now locally. You could then tow your car to an auction site and avoid having to deal with listing & selling it.

Just buy a used parts, installed it and it will work. Second hand charger cost about 500$-1500$

after installing you will need to write key and vin number to that unit. It can be done with Mercedes star diagnosis or a program Vediamo

My batteries have been dead since June. That means they are probably bricked now, doesn't it? I am sure the car didn't get the 2016 update since I bought it from a non Mercedes/Smart dealer in October 2016.

Yes, probably dead BUT what exactly did MB say regarding "part N83" (not a smart part #?) "battery charger control unit" and a $6,000 estimate???

Too many variables, unanswered questions. Does the dash light, what messages? What level was the HV battery when last read? 12V dead?

They didnt tell me much. I need a "Battery Replacement: Systems Battery", which I am assuming is the separate 12V battery and "Control Unit: N83 control unit. Charger is faulty". The car was completely dead since early June. No response, no lights, no charging. Neither Smart service center was anywhere near where we could get it without renting a truck, car dolly and transporting it ourselves so it sat until I realized I could use a AAA tow. I don't want to buy a new 12V battery and a used charger if the batteries are also toast.

I'm planning to part out a ED with a bad cell in the HV battery pack. Charger should still be good. $600 shipped. Let me know if you're interested.

The high voltage battery replacement used to be around $6000.00US but now is 12,500.00US. THAT is probably what MB Dealer is diagnosing here.
