So you mean it's not easy, but two separate ports does make it slightly easier?

I'll look into how the BMS wakes up when using CHAdeMO and report back, thanks!

Anyway, onto some other current issues with the VW Tesla Kombi.

It currently has DC charging via CHAdeMO and the Orion BMS, and 6.6kW AC charging via Mennekes Type 2 port. How hard would it be to swap the CHAdeMO over to CCS2 using the Focci board (or something else), and keeping everything else ...

Yes I did... here: viewtopic.php?t=2669

Could you please share your sdu board parameters?


Well... Short story is... the openinverter board fried my SDU so I wouldn't be using whatever parameters I had!

I had to replace the whole SDU and whilst doing so I upgraded to the T2C controller at the same time. Not without its own ...

Thanks for the confirmation that both can co-exist. I was fairly sure they could, but I'm struggling to find out how the Orion should be configured to have them both enabled.

Do you know what the Max Amperage When Charging is set to (in the Charge Limits tab)?
Do you know what the Max allowable ...

I have Orion with a J1772 and CHAdeMO plug that both work... but I'm not much of an expert so if you need any more info you'll probably need to spell out exactly what you want.

Can someone tell me what program is being used here, over the top of the Orion utility, to get the explanations of the CAN messages?

I'm trying exclusively on Tritium brand DC chargers as they are dominant here, plus I have friends that work there. They provided this useful graph of my charging session attempts, which leads me to the x102 which is causing the error.

Hi all,

I'm unable to charge on CHAdeMO and suspect there is something wrong with the x102 CAN message as I've been told that the car is sending an error flag on x102 to the charger which then stops the session proceeding.

My question is how do I interpret what the Orion BMS is sending on x102 ...

Thanks for confirming my worst fears :( Seems crazy that one little tap on the throttle can destroy an expensive motor, but that's what it is. I knew that the openinverter option came with inherent risks, and I have to live with it.

Are there any photos on the web or here of the IGBTs that are ...

Update from the conversion workshop after checking continuity:

it's zero resistance in one direction and around 50ohms in the other direction on one of the phases. All 3 have continuity but that's not exactly a dead short.

Is that repairable? If not does anyone sell just the inverter board or am ...

Shattered to hear that! It was a fairly innocuous fault / failure, just a slow hill start, not like I was mashing the throttle in a drag race or anything.

We started with all the default settings, then just adjusted a few to follow Catphish's setup, so that's why Tripmode 2 was set as it was ...

Hi all,

Getting my head around tuning the parameters for the first time in my VW bus. Today's test drive was going so well until a STOP - OVERCURRENT error occurred, and then after that I couldn't get the inverter to select a gear (D or R) to drive, so I had to get a tow truck home :(

Backstory ...

Firstly, I am in Australia and have requested assistance from Andrew at Orion but he hasn't been able to provide any help unfortunately (too busy and no access to his CHAdeMO test vehicle... :roll: ).

My 2nd EV conversion - a VW T2 bus with Tesla SDU and Orion BMS (link to project thread below ...

Any update on this amazing project??

It's been a long time since I updated this thread. The restoration of the '73 VW has been continuing alongside the Tesla swap conversion by Traction EV workshop here in Brisbane, Australia. It's been a long, expensive journey but I'm sure everyone is familiar with that.

Fitting 14 Tesla modules ...

I thought it was a hell of a job to modify Tesla modules? Would prefer to avoid that if possible.

Mainly want to know a definitive source of minimum operating voltage for a SDU?

HSR Motors website lists it as 240V...?

Hi guys

How would a vintage VW single cab truck go with a Tesla SDU and just 10 x 5.3kWh modules?

The intention is definitely non-performance, just light duties, etc. Does the SDU operate down to 200V?

Yes, width is a problem, hence my 2nd question in opening post about shortening a Tesla subframe.

The Pontiac's track width is 59" compared to the massive 67" on the Tesla.

I'll see if those Holden made suspension parts are available easily in Australia. But am a bit wary of lots of fabrication ...

The attachment points of the LDU and SDU are the same, the subframe is interchangeable. Do you want to have a rigid axle again or convert to IRS?


Contemplating options at the moment, though prefer to mount it in place of the rigid axle and convert to IRS. It's for a 1949 Pontiac Streamliner. So ...

Hi all

I have an LDU with no subframe, but wouldn't mind finding one - just wondering if I find one that had an SDU in it, would it fit the LDU?

Also, has anyone shortened a subframe before? If so any links to see how it was done?

For background, I'm planning a project to put an LDU in place of a ...

Amazing!! This is a real inspirational build for my '49 Pontiac fastback project that is waiting in the wings (after my current Tesla VW bus conversion project). I want it to be a low slung, stealth lead sled as well, but with a rough patina finish.

Did you design and build the whole new chassis ...

Great article! Is there a thread somewhere about the VW bus with 400km range?

alexbeatle wrote: ↑Thu Jan 28, 2021 12:43 am Mind sharing the pictures of the boxes? Looking for inspirations for my own conversion.

Here you go. Might be a bit hard to picture out of the bus.

We're starting to solder in the Openinverter board into the Tesla SDU now... exciting times.

Looks great looking forward to following this.
Have you any plans already for the battery box(s)?


Yes, the 3 battery boxes have been designed and fabricated to accommodate the 14 tesla modules - one under the belly and two in the rear engine bay. No loss of internal space for batteries. they've ...
