Part 1 of the diagnosis and repair of the Mitsubishi i-miev, Peugeot Ion , Citreon C-Zero, DC to DC converter failure, this seams to be a known issue with these vehicles, and can cost many thousands of dollars to replace, but with some basic mechanical skills, and some soldering of new parts, we managed to repair ours for just $20. the cost of 2 capacitors, and a fuse from Mitsubishi, the fuse was $15.
Part 2 when i recover the footage will cover the actual replacement of the capacitors.
When this fails, the car will fail to charge from AC power, though it will still drive and operate normally, only showing 2 errors on the instruments, 1 of the High voltage system, and the 12 volt system. i believe you can still charge from DC via the Chademo port, though i did not try this.

I saved much time doing the desoldering and soldering in the built in condition inside of the vehicle. It was helpful to have a goold soldering station and a de soldering vacuum pump. Undoing the DC Connection plug under the seat is a must in order to stay safe. There is no cooling liquid in the PCB area.

good to know there is no liquid cooling in the PCB area, at the time we had no idea what the failure modes were, or what we would find, and found it easier to work on a desk. we weren't expecting the repair to be so easy

Excellent video, thank you. Useful for other repairs involving the Charger - DC/DC converter box, too. We've got 4 i-MiEVs here on the Isle of Colonsay, Argyll, Scotland. Fabulous wee cars that we hope to keep going for as long as we can. Mitsubishi management should all be sacked for abandoning this design.

yes, ours is still going strong after all these years, though there is a company here that can refurbish the battery and bring up to 24kwh capacity which gives it about 300km range! Sadly it appears the DC-DC converters are the only real weakness in the car, but once fixed, seem to go on just fine.

it is necessary to remove the entire inverter from the car and you can not fix it in the car and solder new capacitors?

our local dealership followed a simple instruction sheet that was trial and error, they wanted to replace one thing after another until it was fixed. even after we told them what the problem was, they still started replacing parts that didnt need replacing, while we were paying for it.

Why do I need to drain the coolant before opening up the cover just to check if the capacitors are blown? Is there literal coolant in the OBC before I pop open the lid?
@SydneyEV
@SydneyEV 2 месяца назад
if you dont plan on removing the converter then i am assuming you should be able keep the coolant untouched.

Hey SydneyEV Thanks for the video, because of you guys i dared to do it my self. Now I followed everything you did and have replaced the fuse in the MCU also got the same resistors that you mentioned. Although the warning lights dissapared from the car I still cannot charge it. It makes a ticking sound from the fuse box in the front. Im lost, i have taken the OBC out 3 times now to checked everything tired to resolder again but nothing helps. Could it be that i ruined it? Or could there be something else. Anyone with any ideas?

Great couple of videos! I've actually got an iMiEV in NZ which struggles to charge on AC, but will still charge fine on DC Chademo. The AC charge will most likely fail if you start from a lower charge level, but may be ok if it's just a top up. It can randomly show various warnings like the tortoise and ev system while driving. Mitsubishi advise it needs a new battery, but I'm not so sure... what sorts of issues were you having with your imiev? Thanks

Such is the modern world... Oh well, I learnt a lot fixing mine. So I should be able to keep it in the road for a while. Starting to think I might need to repack the cells by the end of this winter though - starting to choose between heater and keeping up with traffic to get home on a charge.
@redcane0
@redcane0 5 лет назад
I think I'd be pushing my luck to get 90km, the last section goes up 500m of elevation. 70km commute. Usually get back with 0-4 bars on the gauge, but I've never hit turtle mode. The drivers seat heater is great, but doesn't work with passengers. I often only use 3 bars on the commute in, I think it's near all downhill. No fast chargers within 300km. Might have to get a slow charger near work.
@redcane0
@redcane0 5 лет назад
That is commitment! Any chance of charging at work? I think that is almost ideal - you can charge during the day when the sun is out. I bought the car accepting the idea that I'd only ever charge at home, and honestly it hasn't let me down yet. The only chargers within 150% of it's range from home are some Tesla destination (slow) chargers, and some (incompatible) Tesla superchargers. These are all really close to the start of the home journey though. I find it a little inconsistent - some days I get home with 2 bars shy of half a charge, other days I'll be on zero or one bars. I suspect colder days are worse (even if I don't use the heater). In any other respect it's such a convenient car though. I suspect that repacking the battery with new cells might cost more than a grey import leaf, but I think it might be worth it.

It seems like a can bus problem ! they will call me later to verify this and tell me the price ! Good news is that the PCBs inside this charger can be buy seperatly and not like in the past the complete charger !
