I have an unused Nissan Leaf 2017 and I attempted to run the drive system outside the car to do some tests for possible future conversions. I simply extended all wires of the drive system (HVB, PD module, and Inverter) to the inside of my garage with around 6.5m extended length.
I've done a single phase version of it for the Gen2 inverter: https://github.com/jsphuebner/stm32-island It uses phase 1 and 3 and also the boost converter to keep DC link voltage constant. So it requires a battery voltage lower then mains peak, say below 300V.
I was wondering if anyone has tweaked Damien Prius Gen 3 Inverter Logic Board yet to run home appliances that work with 220v single phase. And what is the possibility of running a workshop with 400v 3-phase power out of the Gen 3 inverter.
Before being overly hopeful, if something like this ...
