Lordestown Endurance Conversion into Custom EV
I purchased a chassis from a never driven Lordestown Endurance EV truck. It has the VCU, battery management unit, motors, wheels and batteries and charging tech. No cab or heads up display or other electronics.
I am attempting to reverse engineer the software for the VCU and use for a custom VCU. The included VCU is a m560 from OpenECU. I attempted to obtain flashing software (NewEagle.net) to re-write the VCU, but was told they only sell $9K a year commercial license, no individual or hobby license and wasn't interested in helping.
I will be using either a custom VCU i will make using a Teensy 4.1 or buying a ZombieVerter VCU or similar. That is not the hard part. The part I am stuck at is the Power Control Unit interface. It comes with a E-Powertrain Technology Co, Ltd and is manufactured from LgMagma but they have no public info about their units as they usually make custom ones for EV manufacturers. This means the CAN Protocol and commands are likely proprietary and not easily found. It must follow some CAN specific commands for diganostics and such, but there is no info on the pinouts, or nothing. I have contacted LG, but you can guess where that will likely get me.
Lastly, I will need the CAN messages and commands to interface with the motors. They likely work through the PCU but may have a Motor Control Unit separate.
How would you go about finding the commands for the PCU to charge, sleep, etc. Motor commands, etc?
