Dilbert: /* Toyota Inverter Connectors */

This page is dedicated to use of Toyota inverters (Lexus / Camary / Gen3 Prius / Auris / Yaris) unmodified via the serial protocol (REQ, CLK, HTM, MTH). This page also contains wiring and connector information for the various models of Toyota Inverters.

== Toyota Protocol ==

* REQ Request line from hybrid controller to Inverter
* CLK Clock signal from hybrid controller to Inverter (Constant 500KHz)
* HTM Hybrid controller to Inverter data frame
* MTH Inverter to Hybrid controller data frame

A landing page to start adding references to Toyota/Lexus and their suppliers part numbers and what vehicles that you might find them in.

The table below shows the part numbers of inverter units as labelled and as referenced by Toyota in their parts catalogue. Assembly part numbers may include a hyphen in the part number on some records. Label part numbers on the Lexus items are based on the lowest assembly part number. Links to part details are to the US sites for Toyota and Lexus.

Toyota Prius Gen3 Board

2020-01-23T16:17:52Z

Dilbert: added Auris part number to the list of Gen3 inverters

[[File:Prius Gen3 Inverter Control v2.jpg|thumb|Prius Gen3 Control Board v2]]

The Toyota Prius Gen3 Board is an open source project to repurpose 2010-2015 Toyota Prius inverters for DIY EV use. It consists of a circuit board and programming that replaces the original logic board in the inverter and allows independent control of it without communicating with a Prius ECU.

Note that there is also a [[Toyota Prius Gen2 Board]] for the 2004-2009 model years.

== Prius Inverter ==
The Toyota Prius is a hybrid vehicle. Their inverters are suitable and attractive for DIY EVs because of:
* Large part availability. Priuses have been made in large numbers for 20 years.
* High affordability. Prius inverters are available for around $150 from scrapyards everywhere.
* Durability. Toyota engineers appear to have made the inverters foolproof, many inputs and outputs gracefully handle fault conditions.
* Respectable performance. Rated for 50kW output, but tests indicate they can tolerate as much as 300kW
* Ease of repurposing. Emulating the original ECU seems reasonably feasible.

The Gen3 Prius (2010-2015 model years) has a variety of useful components inside the inverter package:
* 2 high power inverters, for the 2 motors MG1 (starter) capable of handling X(?) amps, and MG2 (drive motor) capable of handling Y(?) amps.
* A DC-DC converter to provide 12v power supply to the automotive systems and accessories.
* A boost module to boost the 200v battery pack up to 500v, which looks to be able to function as a battery charger (wish list for future development)
* See this video for a thorough disassembly and explanation of the Gen3 Inverter (Timestamp ???? ): https://www.youtube.com/watch?v=Y7Vm-C4MsW8

== Control Board ==

The current version as of Jan 20, 2020 is v2.

As designed by Damien Maguire, the open source hardware for the control board can be purchased as both partially populated and fully populated and tested boards on his website:

[https://www.evbmw.com/index.php/evbmw-webshop/toyota-partially-built-boards-copy/prius-gen-3-inverter-logic-board-partial Prius Gen3 Partial]

[https://www.evbmw.com/index.php/evbmw-webshop/toyota-built-and-tested-boards/prius-gen-3-inverter-built-tested Prius Gen3 Prius Gen3 Full & Tested]

The control board is a physical replacement for the OEM Prius Gen3 inverter logic board inside the inverter. Remove the old one and replace it with the new one.

== Development History ==

V1 - This board was sold tested but also as a bare logic board requiring purchase of your own components and SMD placement and soldering skills. https://www.evbmw.com/index.php/evbmw-webshop/toyota-bare-boards/prius-gen-3-inverter-bare-logic-board

V2 - A new board source was found to be both high quality and low cost. The boards were redesigned around the inventory of parts available from this supplier. In particular the high cost of populated and soldered boards (10x the price) from the source used to make the v1 boards is so significantly lower on the v2 that there are likely no savings by building and soldering the board yourself. The circuit now has hardware to support repurposing the MG1 inverter as a battery charger, though as of Jan 20, 2020, software is still in development.

== Assembly Notes ==

The Prius Gen3 Board is suitable to control any (please add: motor types here) motors.

Note: Early versions of the board have a few mistakes. (Add details)
