Unfortunately, it is almost impossible to do this now (RU).

Impossible to change the software now? How come?

I modified the firmware of the BMS unit of all generations of Liaf, chip 70F3236 70F3382, in order to expand the range of their operation to the required battery parameters, the most popular CATL 115Ah 120Ah 180Ah..., there is an example of standard BMS30 firmware adapted for BMS24 (3NR4C_BLINK ...

Reprogramming the unit is necessary, otherwise the factory firmware will only process 22KWh, and this is in the case of a wear data reset.
BMS 40KW sees a maximum of 115Ah, and requires a different current sensor.

Is it possible to change firmware and the sensor on a 24kWh BMS so that it can see ...
