Re: Not Charging. Main Inverter Fuse blown

Can you find out the trouble code(s) and post it up here--there will likely be both an EV-ECU code and a Charger code, if that was where the problem occurred.

When you said 72 units, did you mean cars or MCUs or Charger dc-dc units?

Have you found info on any business that is repairing components, we would all be interested to know

Antaris, thank you for posting. Clarification - is that 72 replacement fuses or 72 inverters? Either way, an average of 12/year in one dealership is a frightening number!

kiev, nice cottage business for you if you can suss out the problem.

Purely speculating, inadequate IGBT protection in the design? Google "IGBT Protection Methods" for tons of hits. Would that blow the fuse?

Edit: Been thinking about this, and the numbers simply don't add up. 72 fuse/inverter replacements in six years nationwide would be an unacceptable failure rate, IMO, out of 2108 i-MiEVs sold in the US. (number sold came from InsideEVs.com).

Sorry I should have been more clear.
The dealership where I took my I-miev, claim they have sold 72 units.
That is over a number of years and maybe it is only the 2012 models
that might develop the problem.

The P0A09 code points to the 360V -to- 12VDC Converter error. The diagnostics include checking the wiring, relays and connectors, and testing the operation of the cooling system actuator components (pump, radiator fan, etc)


PROBABLE CAUSES
Damaged wiring harness or connector(s)
Malfunction of system cooling
Malfunction of the DC-DC converter
Malfunction of the EV-ECU

I just talked with the service manager and he says the on board charging unit has failed.
I said from what I have read they are quite expensive.
He said yes, about $4000.00 cdn.
Waiting now to see if Mitsu Canada will give any help, as that part is off warranty.

Perhaps I'm repeating myself, but can the unit be repaired/remanufactured? Replaced with an open source unit?

Or made the subject of an open source project to create something a lot less expensive?

I just posted in "Driving the I-Miev" . The onboard charger has been replaced and Mitsubishi will be able to do post mortem on the failed part. The other I-Miev with the exact same problem was on warranty so that tells me the sickness is not just with 2012 versions. I hope I don't jinx myself, as they are charging the car over night at the dealership and I pick up tomorrow.

Good to know, and the 'post mortem"?
