Part Wanted Wanted BEV EME inverter

[3rigel]

I'm looking for a BEV EME, if anyone finds one surplus to requirements please let me know.

Even a faulty one would be considered if yours went faulty and was replaced I'd still be interested in the faulty unit.

Try ebay

Thanks, yes I have been looking on a regular basis. It seems they're all rex version or the later ones unfortunately. I need something 2013 to 2016 to stand a fighting chance.

[email protected] I have been to there Office and yard they had lots of i3s the most I've ever seen at a breakers yard and there prices are good , I found them really honest and very helpful and know lots about the i3 they actually also do HV battery upgrade and coding, worth knowing hope they can help you Regards Royston

Thanks oldsparks, I followed your advice and picked one up.

The fun then started getting it cleared and then programmed to the car.

I found a guy on ebay that could do the upgrade while the unit was on the car over the Internet. Its only just been done so I'll report back once tested.

Prerequisites were an additional power supply to hold the battery up as the traction battery does not support the 12v while being progranmmed. Your Internet connection needs to be reasonably fast and stable. I had lots of problems with it dropping out. I went ethernet connection from router to pc, ethernet from pc to car to smooth it out as much as possible. You cannot have it dropping out mid process. I had success with 50Mbps. The power supply was my other car with some good quality jump leads.

A lot of time was spent checking and sorting the connection out for me but the actual process is probably under 30 mins.

The down side of this route is you are handing over control of your pc to someone you haven't even met. Luckily i have a dedicated Car laptop with only the usual BMW software. I also dug out an old router not normally used for good measure.

Ill report back with an update in a while but this process although rocky for me could be a route to getting the job done for someone.

A forum member reported increasing the integration level of his i3 without using a 12 V power supply to maintain the 12 V battery's charge level. Instead, he left his i3 in drive ready state so that the DC-DC converter could power the 12 V system. However, the DC-DC converter is in the EME, so that might not work when the EME is being programmed. Correct?

Yes, i assume on the first try that having it powered on would do the trick but i was wrong. In my case once the ignition was on my battery voltage increased to about 14.7v but once the programming starts the EME is controlled via the OBD2 port and it seemed to change state (from supported to not supported by the traction battery) a couple of times during the process. Dropping immediately to about 13.8v and working its way down to about 13.6v im my case. My other cars battery (the power supply) started the process at 14v. I initially tried just a battery charger to maintain battery voltage but this could not keep pace with the current draw.

So, you made a breakthrough... excellent, yeah, the power supply is a tricky one. I learned it when AA tried to "jump start" the car, and connected their trusted jumper kit to my REX. The guy said they usually use it to start trucks, and my little i3 just drained it in a couple of minutes, without even starting up (I mean booting up). So programming, I bought a 100A@12V power supply which worked great when I tried to sort out my issues...
