Re: 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 So naturally, the first thing you did was to rip the covers off :D These will be much easier to repair-- no Waffle Plate™, all the high power diodes and transistors can be seen along the bottom board edges. This is indeed great news. S...

kiev wrote: i took my car to the dealer yesterday to request a new chargger under the extended warranty letter. They said OK, no charge, we'll get it ordered.

I think a collective thanks is in order for Kiev's presumed part in making this happen! :ugeek:

Re: Blown Diode in the Waffle Plate

Now to consider how this plays for OBC failure-- And also how to repair an IGBT in the Waffle Plate™. Layout (for minimizing inductance and maximizing heat sinking) is probably too important to have something external grafted on. Plus, the IGBT probably failed shorted, and so needs to be removed fr...

Re: EV-ECU Reverse Engineering

use mmcflash to read this ecu Alas, the MH8106F chip seems rather mysterious. I haven't found a single datasheet for it as yet. This chip seems to often be used for vehicle ECUs, so I suspect that the lack of data is intentional, to make reverse engineering harder, so people can't do dangerous thin...

Re: Wrecked i-MiEV Battery Pack Discussion

The manuals are online at this Russian site:

http://mmc-manuals.ru/Mitsubishi_i-MiEV/en

I hope that's the sort of manual you mean. It may take a while to find here the information you want is "filed under". It's worth persevering as the detail, when you eventually find it, is good.

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

Kiev,

re the temporary fuse: what's the thinking there? I'm really uncomfortable with a piece of wire to protect a 360 VDC circuit, even temporarily.

Especially when you've just been poking around and changing things.

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

Kiev, re the photo with the saw: nice "hacking" (almost literally :D ). Would it not be possible to suck the solder from the holes from above with a desoldering station, and solder in the new parts from above? I guess many people don't have access to a desoldering station, but patient use ...

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

I followed the advices and the on-board Charger worked again. Well done! After a few days, Eek. But tragically short-lived. while my car was being charged, the fuse of our house was triggered by our high pressure cleaner and from this moment, the Charger does not work anymore. :shock: Well, that' m...

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

I will check the 12 V battery and the 14.6 V in the ready state , but i think it must be in good condition, as it drives the other electic parts such as, e-windows ... It would seem that way, but in fact an auxiliary battery seems to need more than just enough oomph to operate windows etc. Before o...

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

I thought I’d take the $25 gamble. I didn’t try charging but went instead to ‘ready’ where my hopes were dashed with an audible pop from the rear of the car. Huh. So that's evidence that some of the problems happen after the fuse goes open circuit. But I'd like to be clear on the exact sequence of ...
