Charging Fault error.

[BEC]

Interesting seeing what’s inside.

We got our Soul EV back this afternoon - so repair diagnosed, OBC acquired by the dealer and installed from Thursday afternoon to Monday afternoon. I saw the service invoice....the OBC was priced at something like $2290. They also performed a couple of other updates: SA 297 Battery Management Logic Improvement and SA 306 OBC update/inspection. It was probably doing this latter that confirmed my OBC was kaput.

The new one is version P14.1R (made 20170427). The old one was version V12.2R (made 20151214)

I wasn’t feeling well and was resting when they called, but after I listened to the voice mail and was able to verify the state of charge at 98% via the UVO app it was clear they’d gotten it done.

I plugged it in a little while ago and it’s now full again, so things appear to be working.

The only cost to me was putting $22 of gas in the 2017 Soul loaner before taking it back (well, and the time, of course). Driving that gas Soul sure made me miss the EV’s quiet strong responsiveness where the 1.6L engine/6-speed automatic was noisy, hard to control smoothly and nowhere nearly as responsive.

So - all smiles again now. I still hope against hope that the 2020 Soul EV will be in the Seattle area in September of this year (and with this OBC failure mode designed out). If not....we may wind up in a Niro EV. We shall see.

I repaired my OBC.
The problem in capacitors 1mkf

Thanks for posting this - and am glad someone has posted a do it yourself fix.

But a faulty OBC has been opened up before and that simple to swap faulty capacitor wasn't seen. I think there is more than one way for these to fail.

The OBC fix was done at Véhicules électriques Simon André. This is the (first) used EV repair shop in Quebec. So it's not a Kia dealership. As the car was bought in the US, the warranty does not apply here so that's why they were on their own to change the OBC. They took the opportunity to open the OBC case to check if something is broken and repairable.

I'm glad to hear Kia of Puyallup got the job done in a reasonable amount of time. I'm sure I'll be there at some point. I wonder if they'll give me a loaner since I didn't buy the car there?

I expect you will have to call and ask that.

Hey guys. My OBC broke and it has no warranty , so i'm trying to fix it myself. Would anyone might know what these components are?

Well "Rxxx" generally means it's a resistor of some sort. That is good news as resistors are cheap and simple components. Is there any writing on them to indicate spec? You could also use a multimeter to test the resistance across the two sides of them to measure it (ones that aren't fried, obviously).

I'd take the board to an electronics repair place they should have no trouble fixing it.

Agreed that Rxxx should be a resistor. Normally I'd expect surface mount resistors to look like the smaller components above R478 - R481 but these might be high power versions, google "Panasonic ERJ" to see some examples.

My concern is that resistors don't usually burn up. I wonder if some power transistor has died and put too much power through them to cause that kind of damage.

Agreed. Something else must have failed to overpower the resistors.

The resistors R475, R476 and R477 are in series and connected in parallel with the series resistors R472, R473 and R474.

If any of the resistors in the series fails with a short, the others will be carrying more current and likely fail.
Cooling liquid could cause a short, if it were to enter the board.

I suspect that all resistors are of the same value, so if any one is still OK, the measured resistance of that one could be used for all replaced resistors.

Still getting occasional posts about this error -

Not charging, clicking then off

Although it seems that Kia must have fixed the problem because people who have had the replacement aren't posting any more.
