Re: Under the Cover--an Inside Look at a 2018 On-Board Charger (OBC2)

i think if you were to proactively replace the 20A MCU fuse as a maintenance item, then your old OBC would work just fine for a good long time. i'm still doing research on the failure modes. i'm struggling to understand how the MCU fuse could experience an over-current condition and blow, without ta...

Under the Cover--an Inside Look at a 2018 On-Board Charger (OBC2)

i just got kiev back today with the new style On-Board Chargger, calling it OBC2. It has a date code of 2018.05.17 and is quite different from the 2012 version.

Re: On-Board Charger (OBC) Warranty Extended!

ten days and it's done! The dealer called and said it was ready, so i just got my car back with the newer style OBC (9481A171, serial # 00007) . It does not have the little external AC filter box on top. Date code is 2018.05.17 Img/Img No cost to me. Img/Img The biggest delay they said was waiting f...

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

Howdy Jiri, Sorry to hear of your problem, failure of OBC is happening all to often. Christophe was never able to repair or fix his original problem--he bought a used charger that was also failed, but was able to replace the Output snubber capacitors and get it working. His original board was failed...

Re: Citroen c zero not charging and blowing fuse

The little blue capacitors are rated for 2500 Volts and provide a snubber function for damping out momentary spikes on the high voltage output of the OBC. i have replaced those with larger sized caps rated at 6000 volt. The fat black capacitor is rated 310 VAC and provides filtering on the AC input ...

Re: my 2013 Peugeot iOn will not charge :(

The holes are plated thru in the circuit board. There are components on the bottom surface and above the waffle plate that are inaccessible without removing the plate, hopefully nothing fails there or within the plate. The snubber caps are connected in parallel across the output of the diode rectifi...

Re: my 2013 Peugeot iOn will not charge :(

Take a look at page 39-40 of the troubleshooting the OBC thread. i have some extra 6kV caps if you need some. You seem to know your way around circuit boards, so i'll let you know that i used a small gage wire with crimp lugs to replace the fuse for testing purposes only. i have a blown diode within...

Re: my 2013 Peugeot iOn will not charge :(

Good work on getting it opened up, That looks promising for repair since only one snubber has split and no other signs of damage in the doghouse. It may be that these snubber capacitors are the components that triggered the recent warranty extension by Mitsubishi. Take a look at Mouser, digikey, etc...

Re: On-Board Charger (OBC) Warranty Extended!

i got that letter today also, and just in time since one of my OBCs has failed. Awesome service by Mits to offer refunds for folks who paid to replace theirs. Now i just have to wonder which capacitors could be the culprits to which they refer? Big electrolytic or the blue snubbers? But why doesn't ...

Re: I-miev charging problem/ won't charge

Welcome to the forum, sorry to hear of your charger issue. Unfortunately too many folks have experienced this same exact problem. Most of the time the 20A fuse inside the MCU has blown, and this damages some snubber capacitors or more within the chargger unit. See the troubleshooting thread for deta...
