Could someone help me figure out this HONDA BMS?

Post by Offroader » Sep 19, 2017 12:37 am

This is from a Lithium titanate Honda FIT EV car. I have the 30 volt pack with attached BMS.

The BMS doesn't seem to be doing anything, I charged and discharged cells by 1 amp hour and they just stay unbalanced. All cells were balanced by .002 when I opened the pack up.

Some ideas:
Does the BMS need to be powered through the 6 pin connector or connected to the car to work? Does the BMS need to be charged or discharged at the pack level for it to work?

If anyone has any idea on what I could do to get this to balance, thanks.

Pictures below will be cut off, so you will have to right click over picture and use "open image in new tab" and then scroll left and right. Or save image to hard drive and view it.
