Re: my Miev will not charge

Yes, I am grateful for it. It goes a long way to making up for the unhelpful attitude from the organisation when the car developed problems. I think it's just one of those things - I now know that the while the car was off the road several months while I was trying to repair it, there was a working ...

Re: my Miev will not charge

So after being pretty dirty that the charger I got as a recall replacement only lasted 18 months in service, I got a phone call yesterday from the local dealer. They've done a clean out of their storage and discovered my original 2010 charger unit! They were going to throw it out, so now I have spar...

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

Hola Barbagris, I think the first place to check is the fuse for the on board charger, located in the motor inverter. This is under the cargo space in the back. This can contain hazardous voltages, but can be checked with a multimeter. Most likely the "snubber" capacitors in the charger ar...

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

Nice theory, and we've seen at least one pre-charge resistor blow, but most of the time, it seems that they don't. Once that resistor is toast the car even with a healthy 12v battery will no longer start or charge. It could explain a lot of the "won't go to ready" problems. [ Edit: In oth...

Re: my Miev will not charge

Our imiev is now fully charged.

In the end, without the additional work we created for ourselves, we only actually needed to replace the snubber capacitors and fuse in the MCU.

Re: Wrecked i-MiEV Battery Pack Discussion

I took the pack out of my imiev (with help from friends). Were the buss bars painted or coated with something--they appear white in the pictures and look like the surface has cracked in some of the bends? We found ours coated in a grey rubber. In the third picture of the previous post there is a con...

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

That message from the icarsoft means it is not connected properly. I see a similar message if I don't have the car on.

Our vacuum pump is still operating even though the car does not go ready, and there is no voltage at the motor control unit.

Re: my Miev will not charge

Yes, we get pack voltage on the chademo port when forcing the QC contactors to close. Given you have no voltage on chademo port, and a failure to go ready, the only shared circuitry is in the battery pack. There is the main 280A high voltage fuse, and the service plug. Then there are all the cells. ...

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

My understanding is these are only powered through the main (and pre charge) contactors, so they are isolated when the car is not in "ready"?
