Building an Electric Car - EV Parts - Open Source Inverter Wiring

After giving a high level overview of the EV wiring in our Electric Porsche 911 wiring in a previous video, there were quite a few comments asking for more detail, both of the wiring and the components.

I have yet to find software for drawing up wiring diagrams that I enjoyed using, so I have gone for the freehand approach.

the main components I used are
Precharge Relay - Omron G9EJ-1
12Vdc Coil - 15A - 400V switching
High Voltage Relays - Omron G9EA-1-NP
12Vdc Coil - 60A 400V switching
Precharge Resistor - Wirewound resistor
150R - 100W
12V Relay - Generic JD1914
12Vdc Coil - 40A 14V switching
Software controlled relay - arduino relay block clone
5Vdc Coil - 50mA drive - 10A 30V Switching

Alternative Relays
Precharge - Panasonic AEV52012, Panasonic AEV31012
Main Contactor - Tyco Kilovac EV200, Panasonic AEV14012

The board I have chosen is the "Open Inverter" logic board with a Nissan Leaf adaptor board. Full details of this open source inverter can be found here:
https://openinverter.org
And the boards are available to purchase through the shop.
There is also a community growing around these and associated boards built on the same architecture and software here.

I have no association to this other than liking the design and simplicity of the product and I will let you all know how I get on with the boards in future videos.

I haven't given up on the goal of controlling the inverter using CAN commands, however I know if I spent too much longer on it there was a risk that the project could stall as I end up focussing on that. I still want to be able to control the inverter this way, but I will pick that back up once I complete this build.

We do builds and projects with electric motors and on electric vehicles, with a focus on electric car conversions. The automotive world is moving towards electric cars at a great pace, but a lot of these are focussed on the mass market or are very expensive performance vehicles.

We want to see what can be done to create our own performance electric cars using the currently available components. We'll take you through every step of our projects (both successes and failures.)

Please come and join us on this journey.

A note on this channel.
While we try to make these videos as informative as possible, these are not instructions or how to videos. Working with high voltage electrical components is very dangerous and can injure, maim or kill. The same goes for working on cars and motorbikes. If these videos have inspired you to take on an EV project of your own, and we hope they have, we would encourage you to undertake the necessary study, education, training and/or investigations to familiarize yourself with tasks you are undertaking. Thanks for watching and we hope you have enjoyed the video.
