Pack Voltage versus SOC graph or table ?

i was searching for a graph, chart or table of this data--seems like someone posted this before but i can't seem to find it using the search. Just a simple table of battery pack voltage at 10% SOC increments would be helpful. i know that 100% SOC is about 360 Volts but didn't have a feel for the res...

Re: my Miev will not charge

... I'm a bit worried that it is not actually the problem, and will result in another couple of months delay without making any progress, even if I don't need to pay for it. If the car runs and drives then some pieces of the EV-ECU have to be working, so it is puzzling. Maybe the section that contr...

Re: Decyphering iMiEV and iON CAR-CAN message data

i can't help with the python code, but here is the CAN buss frame format, if that would help you. The PID is found in the arbitration field, the number of data bytes is 4 bits in the control frame, followed by the actual data bytes and a checksum.

Re: Is my battery dying ?

... Yes I understand that, I was just wondering what scenario would cause the car not to charge to 100%. In my case i had a lagging cell. It somehow discharged below the level of the others and would never come back up. So it was the first to hit the bottom and limited the driving range, and it nev...

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

Howdy skylogger, At first i wouldn't think this possible, but then you noted that these were home-built evse units that failed--so we don't know what they are doing within with respect to the charging protocol, ground checks, communications, etc., and i think you have a good theory. i hope you get t...

Re: Is my battery dying ?

Does the car charge to "Full", i.e. 16 bars on the fuel gauge? Failure to reach full is one criteria for pack replacement under warranty.

What does the canion graph look like when the pack is fully charged using your home EVSE? How much is the peak difference in cell voltage?

Re: my Miev will not charge

Obviously the car won't go to READY with the service plug disconnected. Coulomb wanted you to remove the MCU fuse and see if the car would start with the OBC/DC converter power connection to the pack removed, i.e. the temporary fuse removed. As a safety concern, there will be HV on the big capacitor...

Re: my Miev will not charge

Just a note, from what I've seen of the service manual, there is no mention of the fuse - the troubleshooting flow chart suggests replacement of the EV-ECU and charger/DC-DC after checking the wiring harnesses and relays. It seems like quite an oversight in the troubleshooting process. i think all ...

Re: my Miev will not charge

In Skylogger's first repair there was also a displaced resistor on the bottom board that prevented operation of the OBC. Maybe he could help you look if yall are nearby in WA. (is anything nearby in WA?) The trouble codes might provide a clue if you have a way to extract those, e.g. MUT readout by d...

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

.... On this one we can see the fused resistor. I did not see last time. We also see that the rubbery potting has boiled. Questions: 1) should I change the capacitor as a precaution? I have not found a supplier in Europe for the Okaya capacitor, do you think that one is correct? https://content.kem...
