Re: my Miev will not charge

MIKEDUFFY: I just took the EV-ECU that came from Chris's IMIEV and swapped it with the one in the Wrecked IMIEV Testbed. It started in READY No problems, then took it for a short drive, then put in on charge just to make sure no errors came up while in charge mode. All worked great, never even came ...

Re: Troubleshooting and repair for On-board Charger (OBC), DC-DC Converter

mikeduffy: It sounds like you had the charger replaced under warranty, but are are still having issues at the dealership? I sent you a PM, and I might have spare parts that could be used to trouble shoot EV-ECU issue. Is it possible for you to get your hand on / keep the original broken charger? I w...

Re: my Miev will not charge

Mikeduffy: Just came across this thread and that your car is still at the dealer. It appears that on the report when you first took your car to the dealer, one of the items listed is re-programming the EV-ECU. Now it sounds like they want to replace the EV-ECU. I think the first fault was the Charge...

Re: Troubleshooting and repair for On-board Charger (OBC), DC-DC Converter

Hi Kiev , Coulomb: I might get a chance to work on another IMIEV Charger. I got a call last week that another member of the AEVA (Australian EV Association) has a IMIEV that is causing problems when plugging into the Bollards at the University of WA to charge, and so far it has caused two of the Bol...

Re: Troubleshooting and repair for On-board Charger (OBC), DC-DC Converter

ChristophER: 4.7R at 5watts is a probably not good enough, as the original was a 7 watt rating. Try looking for the 7 watt or or 10 watt versions on Digikey. When you test the relay, you might want to try opening and closing it 20 or 30 times and see that it goes to zero ohms each time. with micro p...

Re: Troubleshooting and repair for On-board Charger (OBC), DC-DC Converter

ChristopheFR: In this picture, the resistor on the left is the faulty resistor that I removed from the charger that I fixed. It appears to have a 7 watt rating. The resistor in the middle is a close equivalent that I found and purchased from DIGIKEY online and shipped from the USA. The setup on the ...

Re: Troubleshooting and repair for On-board Charger (OBC), DC-DC Converter

Great news Electronpusher It is now looking like the majority of faults on these chargers are not major "power train" issues I'm starting to think that either there is a power surge, or like KIEV says, a low 12v aux supply which puts the chargers controller into a destructive state. If the...

Re: Troubleshooting and repair for On-board Charger (OBC), DC-DC Converter

Hi Electronpusher: I agree with Coulomb on his suggestions on both the heat sink compound and the potting. For the potting, I would definitely stay away from epoxy mix, as if you ever need to re-work again in the future, there would be a lot more drama's digging through a hard epoxy rather than a ru...

Re: Troubleshooting and repair for On-board Charger (OBC), DC-DC Converter

ChristophFR: I'm still not sure that you are on the correct test point for your green wire on the right of the photo. I had a look at the photo again, and it looks like you have the green wire shoved into the female blade connector on the white wire, but its not clear what do you have the other end ...

Re: Troubleshooting and repair for On-board Charger (OBC), DC-DC Converter

ChristoferFR: It's a good thing Coulomb pointed out that you have the battery polarity wrong. Connecting it the way you show, will blow the diode, and that particular diode is a bit hard to identify. I think we might suggest putting a resistor in series with the battery in future documentation on th...
