'''Getting Vehicle Road Legal'''

Comment on DIY Electric Car Forum 20th April 2020;

"contacted MIRA and have had it confirmed a certificate of compliance with R100.01 will cost around £5K i and have been given a provisional form to fill then a phone call which has obviously moved on since i contacted them before - not sure I'm really ready yet but it seem a more formal process is in place."

Would seem to make the following comment out of date;

"Convert the vehicle, insure it, get an MOT, inform DVLA of the fuel type and tax class change. Take vehicle for an inspection and wait."

"contactors get extremely hot from 12v power when closed for extended periods of time" ([https://openinverter.org/forum/viewtopic.php?f=10&t=738&p=10661#p10657 here])

Testing suggests that Tesla contactors require economizer circuits and it's important to note that the Open Inveter boards do not currently implement this functionality.

GIGAVAC publish an application note on how to use contactors ([https://www.gigavac.com/sites/default/files/AN-016-Driving-Contactors-w-External-PWM.pdf here])

Information provided by Anne Kloppenborg founder New Electric Group (http://www.newelectric.nl/)

"Converting vehicles to road legal EV in the Netherlands:

To apply for a vehicle to be inspected by the RDW for approval, first there must be documented proof the installed system is EMC compliant to UN R10 rev. 5 standard.

This can be done by a certificate holder (like New Electric who has 3 full compliant systems) who declares the system has been installed with their permission and according to the same standards as during the testing process.

Alternatively, one can apply for waiver of the the rule. by showing all system components come from a single mass produced EV car that has full type approval within the EU (a Model S, a Leaf, etc.)

This second route is not foolproof and can lead to protracted 'discussion' with the authorities, but there is precedent of successful and licenced conversions.

Once the EMC bump has been navigated the car can come in for inspection and road testing at RDW facility in Lelystad. There they test for compliance under ECE R100 rev.01 (electric safety in road vehicles). We advise anyone that is doing a conversion to read and understand this standard throughout as there are gotchas and details that need to be be navigated.

Finally the inspection will check if the converted vehicle still complies with the original type approval (weight, weight distribution, braking straight line, dynamic braking). If a weight increase is such that it needs to be updated in the vehicle registration then they will fully load vehicle with max occupancy weight and do full lange change testing.

If all the above is passed and document revision shows no anomalies, then the car fuel type will be updated to E!

pro tip: if at all possible, get a full fresh 'APK' (MOT) report and certified axle weight report on the car before conversion. Document the weight of components coming out and try to have weight increase distributed such that you stay within about 10 - 15% of the original front/back distribution."

Lexus GS450h Drivetrain

2020-04-01T21:42:49Z

Kevin Sharpe: /* Dimensions */

[[File:Inverter connector.png|thumb|GS450h inverter external connector|187x187px]]
The Lexus GS450h VCU is an open source project to repurpose 2006-2012 Lexus GS450h inverters for DIY EV use. It consists of a circuit board and programming that communicates with the original logic board in the inverter and allows independent control of it without communicating with a GS450h ECU.

Note that the Toyota Camry hybrid (US market) uses a similar inverter with the same logic board, which is functionally identical to the GS450h unit.

== GS450h Inverter ==

The Lexus GS450h is a hybrid vehicle. Their inverters are suitable and attractive for DIY EVs because of:
* Good availability and price - an inverter and "transmission" can generally be purchased for less than £/€1000.
* Durability. Toyota engineers appear to have made the inverters foolproof, many inputs and outputs gracefully handle fault conditions.

* Respectable performance. Rated for a combined 250kW output.
* Ease of repurposing. Emulating the original ECU seems reasonably feasible. The transmission is a similar size and layout to many RWD transmissions.
The Lexus GS450h (2006-2012 model years) has a variety of useful components inside the inverter package:
[[File:Toyota Camry Inverter external connector.png|thumb|204x204px|Toyota Camry Inverter external connector]]
[[File:Inverter connections.png|thumb|GS450h internal inverter connections]]
* 2 high power inverters, for the 2 motors MG1 capable of handling X(?) amps, and MG2 capable of handling Y(?) amps.
* A boost module to boost the 288v battery pack up to 650v

== GS450h Converter ==
A buck/boost converter lives within the inverter housing, originally this is used to step up the 288V battery pack in the GS450h to the 650V for use in the inverter. For those using a 600+V battery pack, this converter can be used to step the voltage down to a more reasonable level to interface with charfgers, DCDC converters, heaters, AC compressors, and other components which can be found in "regular" EV's (Tesla, Leaf, Volt, etc).

This unit is rated at 30kW, making it unsuitable for traction power, but good for auxiliary devices.

Details on how to control the converter are here: https://openinverter.org/forum/viewtopic.php?f=14&t=538

== GS450h Transmission ==
[[File:Inverter.png|thumb|213x213px|GS450h inverter]]
The transmission contains two "Motor-Generator" units. MG1 sits at the front of the transmission, and interfaces with the internal combustion engine through a planetary gear set. For this reason, to obtain torque from MG1, the input shaft of the transmission must be locked in place. This is usually done using a splined coupler, which is then welded onto the transmission front mount.

The input shaft on the transmission has 21 splines, with a 28mm major diameter. It is believed that there are several Toyota clutches which will have this in their centre. The original GS450h flywheel and coupler also contains the appropriate slined centre, of course.

The fluid fill port is the banjo bolt for the upper transmission cooler hose. The specified fluid is "Toyota WS" ATF.

It is a good idea to replace the two bearings in the electric oil pump before fitting a used transmission. There is a guide [http://carlthomas66.blogspot.com/2016/03/lexus-gs450h-transmission-oil-pump.html here]. Bearing part numbers are 61900-2Z and 608-2Z, you will need one of each.

The shift position lever on the right-hand side of the transmission engages the parking pawl when in the "all-the-way-back" position. All other positions disengage this pawl. The R, N, D, M positions only affect the output of the shift position sensor.

Note the following when purchasing the transmission:
[[File:Shift position.png|thumb|154x154px|GS450h shift position sensor]]
* It is recommended to purchase one which has the electric oil pump fitted - these are a costly item as the bearings in them often fail, in some cases they cost more than the transmission.
* It is recommended to purchase a transmission which includes the wiring harness, or at least off-cuts of the connectors. Some connectors may be unavailable for purchase. There is a thread [https://openinverter.org/forum/viewtopic.php?f=14&t=271 here] which covers the connectors on this transmission.

=== Dimensions ===
Overall height (oil pan to top of bellhousing) is 39cm. Bell housing is full height, i.e. 39cm diameter, when the transmission is sitting on its oil pan (as it is on my bench), the bellhousing still just about touches the bench.

Widest point is 40cm, includes a bump for a starter motor which I don't believe the GS450h even has. Likely leftover to mate with the 2GR engine.

Overall length including tailshaft, output flange, and pilot shaft, is 82cm.

Transmission is tapered quite heavily, the width and height is closer to 25cm after the bellhousing, but hard to gauge due to various outcropping parts (motor cables, oil pump, PRNDL selector, etc)

Weight 128kg.

== Wiring Harness Connectors ==
Here are a list of connectors required for the GS450h transmission & inverter if you need/wish to build the harness for your build. (It is a good idea to find components with at least the connectors to build on. As some of the connectors are impossible to obtain)

==Control Board==
An open-source VCU, designed by Damien Maguire, can be purchased as both partially populated and fully populated and tested boards on his website:

[[File:Oilpump.png|thumb|163x163px|Oil pump]]
The VCU is an external unit that will not fit within the GS450h inverter housing. It does not replace the GS450h inverter control board, instead it interfaces with it over USART.

For those who have purchased the fully built board, the mating connectors for the VCU are Molex parts:
* 33472-2002 (Left side, grey in colour)

* 33472-2001 (Right side, black in colour)
* 33012-2002 (Crimp terminals)
These parts are available from many electronics distributors.

==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/gs450h-bare-pcb

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. Software is still in development.
==Vendors==
There are currently no vendors who offer support on any aspects of the GS450h VCU.
