Legalities

• Legalities around conversion projects

Basics

There's a variety of methods of repurposing these OEM components. Methods here are generally chosen with future proofing in mind , reducing chances of firmware or software updates from the manufacture "bricking" or blocking the open source control efforts. such efforts include:

• Mainboard/brain replacement
• CANBUS/LINBUS
• Sync serial
• FlexRay
• PWM

Glossary of Terms

It is recommended you read the Glossary of Terms before you begin. Often you'll find TLAs (three letter acronyms) peppered through the support forum and on this wiki, take the time to familiarise yourself with them before hand, remember this exists, or bookmark/favourite it so you can referent back to it.

Open Inverter Projects

Open Inverter (Core Project/s)

	Description / Notes
ZombieVerter VCU ZombieVerter VCU Web Interface OEM component compatibility	Designed around a matched pair of Inverter and Motor taken from the original OEM vehicle the ZombieVerter is there to make those two components believe they are still in the original vehicle and are fed necessary commands to act as if they still are and interpret and responses back from the equipment for feedback (regen / rpm / etc)
Open Inverter Hardware Hardware Theory of Operation Schematics and Instructions - for the "vanilla" inverter kit. Mini Mainboard Foccci (CCS interface) Main Board Version 3 Main Board Version 2 Main Board Version 1 Sense Boards Gate Driver Legacy Sensor Board OEM Repurposing	Quite flexible in its application. The Open Inverter can be used to build a custom inverter itself where you supply the high power and high voltage components to create your own inverter, or to be used as the basis to take over control of OEM inverters so that they can drive nearly any attached motor to that inverter.
Open Inverter Software Using FOC Software Downloads Features Web Interface Battery Charging Errors CAN communication Parameters (Tune your inverter) Configuration Files Software Theory of Operation Open Inverter Testing	Two of the more important software aspects to master are below.
	CAN communication Common across boards is the ability to communicate with a CAN Bus, which is a 'control area network' or a technical way of saying how various components, sensors, controls, etc communicate with one another within the car. Read more about CAN Communication There is also a project to standardise the messages across the various control boards, read more
	Parameters The openinverter firmware uses a set of about 70 parameters to adapt it to different inverter power stages, motors and position feedback systems. Also it lets you calibrate the throttle pedal, change regenerative braking settings and so on. Parameter definitions can be found here: Parameters Working parameter sets can be found in the openinverter parameter database

Open Inverter Related Projects (Control Boards/VCUs)

Project	Description / Notes
Tesla Small Drive and Large Drive Units:	Commonly there is a large drive unit and small drive unit available from the Model S. These combine the inverter and motor into a single package. The control boards for these replace the existing control board within them.
Lexus GS450h Drivetrain:	The GS450h contains a gearbox (where the motors are located). Using the ZombieVerter VCU, the inverter and the gearbox itself provide a powerful set up suitable for rear wheel drive set ups, replacing the existing longitudinally mounted gearbox.
Prius Generation 3 Inverter:	A cheap available inverter from the popular Prius hybrid, this board goes inside that inverter and allows you to control the features of it.
Auris/Yaris Inverter:	Similar to the Prius board, there's subtle differences between them and therefore the need for a separate board.
Nissan Leaf Gen2 Board	Replaces the nissan OEM logic board with a rev 3 openiverter main board
Ford ranger ev board	openinverter kit for the ford ranger ev
