Can't wait for the youtube comments when they see me working away with bare hands, no flash suit and no $$$ orange tools :) I believe it goes "Damien, you're doing it wrong"... Funnily enough, I'd just posted about PPE on the DIY Electric Vehicles Facebook page with the obligatory link to...

I had another thought, is auto-tuning of a motor possible, if the motor and resolver parameters are known? Like an automated FOC tuning process like in the recent videos by yourself and Damien, but using sensor feedback to know when the tune is correct?

Assuming that vehicle weight and wheel diameter are factors that would effect the tune, is it worth including that, or is there another calculation for that? Final drive ratio for RWD or AWD (if a motor with reduction gear is centre mounted, in place of a transfer case) may also be a factor.

Do you think it would be possible to add CHAdeMO to a Renault Zoe ZE40?

Hi, I've been considering buying a Renault Zoe ZE40, as Renault are dropping the Zoe from their lineup here in Australia, and new old stock or dealer demo models are selling for around 30% off the standard list price (List is $52,860 AUD including on road costs, most for sale are $36,990 AUD includi...

Did you find anything useful in the OpenDBC link I posted above? I suspect it also won't have any HV data, but it may be worth a look.

Here's another source for DBC information for the Model 3 (I assume US version?) - https://github.com/joshwardell/model3dbc

Has a DBC file been created for the Open Inverter CAN signals?

BMW have issued a recall on a number of their PHEV models, due to the potential of contamination within the packs, which may cause a short. It's worth checking them carefully before use.

-IF AMERICAN: an app to covert kW to Freedom Units (HP) so you can understand/communicate power levels :) ROFL! After I've stopped chuckling about your Freedom Units, I'd like to thank you for adding to the list. I forgot about the HV battery isolation and quite a few other bits. Thank you. I'm sur...

While the components may be covered in detail in the EV conversion hardware thread in General (https://openinverter.org/forum/viewtopic.php?f=9&t=335), it would be great to get a basic list of what components are required to do an EV conversion. There are the obvious items such as: - Motor (stan...

If I find any similar resources, I'll add links to them.

Is there an appropriate section of the Wiki to link from? Should pages be created for each OEM and then tables for models?

That is cheap! I may have to talk to some freight forwarders...

This spawns an idea. What if you had a button on the web interface saying "Post my parameters to openinverter". It would then ask things like motor model, inverter model, nominal battery voltage as metadata to go along with the parameters. On the server side I'd set up a small database th...

The inevitable travel down the rabbit hole has begun. It seems that each manufacturer has DBC files to define what each CAN message means, to put them in a more human readable format. There seems to be a fair bit of work out there to reverse engineer CAN messages to build the DBC files. George Hotz'...

We'll just have to keep watching...

Reusing existing EV and Hybrid components is a great idea, and the work that the Open Inverter project has done, is great, but for new players, it can be difficult to know which inverter to get that one of the Open Inverter brain boards will work in. Using the Toyota inverters as an example, which s...

The "mad man" has a new video out. He has aspirations to create a new type of EV.

light update: Asked my wrecker for another Leaf "engine assembly" since they're SO cheap. Just to have around for a possible future project. How cheap is SO cheap? They seem to be in the $1500 AUD ($1055 USD) to $2000 AUD ($1407 USD) range for the drive pack (motor/inverter/charger for th...

Hi, One topic that always seems to be big and scary in the EV conversion world is Can bus. Since I've discovered the Open Inverter project, I have learned that it's not as scary as people make out, but there is still a lot to learn and when converting a modern vehicle there are many potential concer...

There was a guy in Sydney who did a conversion of a Mk 1 MR2 a few years ago - http://www.evalbum.com/1759

Thanks for the info. I guess it depends on which vehicle is being converted and who's doing the work to know which option would be the best choice. In regards to the vacuum pumps, it would be good to compile a list of manufacturer part numbers, so they're easy for people to find. I had referenced th...

Yes, the newer motors are Bosch SMG 180/120's, good for around 100 kW, used in the rear of the Peugeot 508 Hybrid, the Fiat 500e, and others.

So no one succeeded in getting the old motor to run? If they did the ballyhoo would be overflowing fer sure. [sadface] Thanks much, now I know what is in this rat's nest: I'm not aware of anyone getting it running, but I haven't done much research. It looks like you've got the lot with that haul. I...

Hi, I've been researching electric brake boosters, preparing for my first conversion project.
