HI all.
I am building extra battery for my Nissan Leaf as well, reading this tread gave me a lot information to think about.
My battery will be small, only 8.5 kwh. And build on 18650 cells. So problem with over current during rapid charging and discharging actual for me as well.
As we know, BMS of original battery can send commands to limit power of motor inverter - during discharge, or send signal to rapid charger to limit charging current.
So idea is to sens current to additional battery, and when necessary send canbus command to limit charge or discharge.
What you think, how possible it will be?
Another option, to false original BMS to think that battery to hot, and it will automatically will limit current from rapid charger, or to motor inverter.
