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

Hopefully that is the case; but doubtful as Mitsu seemed totally surprised. Wasn't there a poll to tally with year info ? I believe kiev started. I've been charging DCQC almost exclusive for a year now. But during the recent multi days power shutdown in California due to wind&fire; I used the iM...

Re: 12 kW chademo charging

Looks like that Sunny Boy Storage inverter is finally coming to the US market this summer. http://www.freecleansolar.com/SMA-Sunny-Boy-Storage-3-8-Battery-Inverter-p/sbs3.8.htm $2500 for 3.8 kW solar and 2 kW backup from a 360V battery pack. I'm picturing that with a Chademo cable on the Sunny Boy ...

Re: Battery Capacity Testing

https://photos.app.goo.gl/S5aaTvQkqG96dP716 hope the photo link can be viewed. It's the Canion Ah history screen of my 2014 since Dec 2018. I've been QCDC charging almost exclusively (to around 80% SOC) , trying to save the onboard charger. The Ah decline line worried me a bit, but it seems to corr...

Re: Supplemental cooling for the charger.

I am sure there is a 12v source back there somewhere but I don't have access to the drawing. I've been thinking of tapping into the coolant pump 12v, which runs intermittently while charging, so then the cooling fan would only run when the pump is running. My thinking is just to duct the flow to get...

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

So it seems a weak 12v aux may not be a culprit then ?

Also, perhaps we should take preemptive action to deal with the marginal fuse contact integrity ?

Re: Battery Capacity Testing

By "calibration charge", I meant to charge from the blinking 1-2 bars to 100%. My understanding is that when the guessometer hits 2 and below bars, the BMS goes into some sort of integration mode to reset the available Ah. In fact, I don't understand how does the software calculates and re...

Re: 12V battery BCI Size?

I happen to have a couple of those UPS 7A LiFe lying around unused, and no I would not pay the extra $ just to get them. It just bugs me that the EV manufacturers are still using lead for the aux, and in particular Mistu because of the potential harm to the charger/inverter. In general, EVs are so &...
