i wonder if there might be a Boot pin on the JTAG interface on the BMU board? There seems to be 2 approaches to modification of the battery capacity for upgrading or replacing the pack with larger cells, either spoof it with a CAN bridge (man in the middle) or change/reprogram the value in the BMU. ...

I've just joined the forum and have had my i-MiEV for a few months now, and am looking to see what I can upgrade, in particular the on board charger, perhaps to a 11 kW or 22 kW unit.

How would you provide for cooling of the charger and pack with the higher power charging?

take a look at the github/dkotin/can_2515 folder for examples and details, schematic, etc.

drcat put the exact site link in his video above.

My guess is that the OBC only gets powered up during charging so there is no CAN buss activity during READY.

To test this you could just unplug the connector to the OBC and see if it goes to READY or not and throws a code. If it works then you could proceed with the plumbing bypass.

There is a thread about the circuits on the CMU boards, take a look here for a photo of the board with the parts identified;

The LTC chip is a battery management chip, read cell voltages and turns on the balancer bleed-off transistors, etc.

Howdy Mickey, i would guess that the CMU board has a defect, such as power supply, loose connection or some other issue that is causing false readings. The car thinks that one cell is nearly full so it won't allow charging; the 3 errant temp readings are 3 different sensors on the CMU board--not lik...

Hello. I am from Ukraine, from the Dnieper. I am looking for boards - CMU modules, since one is completely out of order, one is non-working and two with data flow errors. Thank you all for your help

i found a picture and description for the MAB-066 at an Australian parts shop that shows the stepped taper in the rubber ends such as what i saw on my 2012. https://auto-parts.com.au/mab-066-rear-arm-bushing-front-arm.html [Also found on AU ebay site: https://www.ebay.com.au/itm/263133879170 ] https...

Where is AC circuit breaker B16 located? i'm not familiar with B16 and don't understand. If you have tried 3 OBCs in this same car, then i suspect you have an external problem such as with the EVSE or AC Mains voltage supply or wiring, etc. You will need to get to the root cause of that problem befo...
