Nissan Leaf Knowledge

For those interested in getting a gen1 or gen2 nissan leaf motor/inverter hacked into your vehicle of choice, there are a few things to know.

The motor controller can be used with this CAN based controller from Thunderstruck EV.

And there is one controller by Johannes Hübner that I can't find. The Paul and Sabrina leaf module replaces the logic board in the inverter with their own design. The features look imoressive!

Looking into the max power out from the inverter, it is set by the power side. 72S is needed for full output power, still unsure of max voltage. Inverter uses 1A at 12V to operate, not terrible.

The DC/DC converter located on top of the motor controller or part of the PDM (Power Distribution Module) can be reused. According to the below, 10V PWM signal running at about 9 HZ on pin 1 and pin 3 goes to +12V to enable. Changing the frequency changes the voltage out, no clue on the relationship there (just don't do 470VDC).

This is the fuse that came with the Nissan Leaf battery disconnect. It is the 225A one. Looking at the current vs time chart, it looks like it can handle 450A without ever blowing, at 500A it takes 30 seconds, and at 650A it would take 8 seconds.
