Hey guys, bit of an update. I have been trying to find an OBC for Keivan and eventually calling around lots of places Graham from Suzi Auto in QLD put me onto Mark from EV Canberra. Both awesome guys. Mark has a wrecked iMiEV and me clutching at straws, got the OBC from the iMiEV to try putting it into the MiEV. Andy from Victoria has been helping me out a whole lot and I don't think they are interchangeable.

If anyone has any contacts with people in Japan who might be able to locate a OBC for a 2012 MiEV that'd be amazing. I'm really in a bit of a pickle. I can't keep charging Keivan from the fast charge stations forever. There is another concern though as well, even if I do get an OBC for Keivan. There is no guarantee the issue that happened before won't happen again to the new OBC. I've tried reading the MyiMiEV thread about fixing the current OBC but it's like learning a new language with all the acronyms and circuit maps etc. Unfortunately I'm in over my head here

If anyone would be able to sift through the 64 pages with me that'd be really great. I'm happy to learn and /or even pay someone to help to fix the current OBC. I really don't know what else to do or who to speak to.

Thank you and I hope I can help others like me in the future,

- Liam

For those outside Australia, QLD (Queensland) and Canberra are in Australia.

Liam, where are you located? I'm a bit stretched at the moment, but it might be a quick fix if you are located near Brisbane.

Edit: Oops, I see from your nearly identical post in the AEVA that you are from Melbourne.

Hello, I bought a favorable Peugeot Ion in 2011, with a defective home charger. His reach was 30km. I managed to restore filling at 100% with a quick charger in lidl. I could only charge up to 70%. In the charging process I disconnected the 12V battery and the charger displayed a fault at 44% charging, then I returned to 12 battery and jumped to 64% on the charger. The range jumped from 30km to 65km. I accidentally accidentally managed something that no mechanic could discover 2 years. :D

I don't want to remove waffle board (but I can - it just takes time), so I will try to reach resistor contacts by soldering iron or may be I will try to cut bad resistor to reach his legs. Also I checked diode voltage drop and it looks fine.

I repaired charger. I changed resistor-fuse and disappeared capacitor.

Hi everyone in this forum,
First I like to say shame on the manufacturer Mitsubishi that build cars with secrets expensive problems! They have no honor and they are like eligible thieves!
If the charger goes bud they do not repair it and neither provides you with the boards that is in this charger like Toyota is doing! They charger cost 4200 euro and that is a lot of money for this car if you consider that in view years you must give (until yet) 10.000 Euros for the battery!
I buy this car for economy reason but this car is more expensive to drive than a regular diesel car if you consider charger and battery cost!
But I have it now and I like to make the best of it!
Some time ago I had a problem with the car. The car after a full charge starts and drives ok in the morning. Then I plug in the fast charger (220 Volt) and I hear the integrated blower started for a 2 second like always it did and then nothing! Not indication at the dashboard and no charging indication on the 220V outside voltage checker!
I open the Charger on the car to see if I can see something but nothing suspicious!
So I contacted Peugeot and take it to them! 6 month they are trying to figure out what is wrong with the car! They told me that the Peugeot France cannot communicate with the on board charger. And the thing the top board has an issue but they don t sell it separately. So the change all the charger for 4200 Euros and the car work again! So now I have a Charger on the car that work and the car is fine again but I also have a defective charger outside the car that I can compare both and is easy to fix the second !
My question here is can I safely change the boards and see witch board is not function and with little help from here to fix it?????

Howdy Matheos, and welcome to the forum, sorry to hear that you had OBC issues with such expenses.

For sure that is the reason for this thread, to help determine what has failed and how to repair it.

There are 3 boards inside the OBC/DCDC Converter; 2 for the OBC in the upper chamber, and 1 for the DCDC in the lower chamber. You can see pictures and many details of failed parts on the first page of this thread to help you get started.

It is so many where to begin and where to end! I am a Pc technician and electronic guy, so I have some experience with boards but I have no similar issues like the fellows here! at least I think so because I have no trouble codes!
But the question is is it safe to interchange the borts between the new one and the old one to find the trouble? I am sure they have the same vin code ! suggestions? :?: :!:

And 1 more think, It will be easier to track the problem if everybody at the and tell what did they do to fix the charger!
With few word! Problem …..>solution!
Another solution that I suggest is, that the charger has 3 motherboard so what defective parts has been changed until yet in the first board in the second, and in the third! So it will be easily for the new ones to spot the defective parts and replace them! So simple! Now you must go from side to side 65 especially, searching for your specific problem! If we Exclude this 2 blu high voltage capacitors everyone else I don t think they have find a solution!
