Re: BMW E46 Coupe Conversion
You're right they look very familiar. Good Lord makes my version of how to control the motor look pedestrian. Actually, its just JBs simple circuit on page 3 and 4 that's controlling the motor. The rest of it is IO, sense checking and a micro to run the Prius DC to DC convertor and provide CAN mess...

Re: BMW E46 Coupe Conversion
Hi, sorry for not replying sooner. A few distractions here! I've not posted the files on GitHub as I've found a few problems which I was going to sort out before doing so. If you want to have a look, I've posted the schematic in the following repo: https://github.com/andymartell/Prius-DC-Motor-Conto...

Here's a screen grab of what we have so far. The boards are on their way from China after Chinese New Year.

Re: BMW E46 Coupe Conversion
Hey Jack,
A bit slow I'm afraid. Working outside so sometimes the weather gets the better of me. Trying to get things together to do a road test. Just putting the battery pack together. I was thinking today that an estate would be better than a coupe!

Re: Rev 3 main board now fully open source!
Hey Johannes,
No need for KiCAD for 3D, Eagle and Fusion360 can do it. Some of the parts need models, but quite a lot is already there:

Re: 4-channel BMS with daisychain bus
I realised there was a mistake on the Huebner BMS wiring diagram I made. The connections on the 1st isolator module connector JP2 were reversed. Also I swapped the position of JP2 and JP3 on the diagram to match the actual PCB: Huebner BMS Wiring Diagram.jpg I've updated the version earlier in this ...

That's great news. In the meantime, I think there was a plan for a high level linux computer (RPi, beagle board) front end. Is there something available to try out?

Re: 4-channel BMS with daisychain bus
For anyone building their own version of the Huebner BMS, I've just corrected a couple of errors in the Isolator BoM (RS485 Version). The crystal should be 11.0592MHz and the processor should be an ATMEGA88P.

Re: Toyota Gen 3 inverter charger
Hi arber,
The part number on my inverter is G9200-47190. The control PCB was F1759-47070/05. The 05 is in a white square and looks like the revision number. It came from an Auris according to the breaker.

I've created this wiring diagram for Johannes' BMS and added it to the Wiki as well. Huebner BMS Wiring Diagram.jpg This diagram has been edited. The connections on the 1st isolator module connector JP2 were reversed. Also swapped the position of JP2 and JP3 on the diagram to match the actual PCB

Hey arber, Looks like an interesting project! I've made a DC motor drive board from Damiens Prius design (not yet published as there are a couple of mistakes I want to correct beforehand). There were a few things I discovered which may be useful to you. When my inverter arrived, the board was not th...

At that sort of price, the blue pill might be a candidate for the CAN version of Johannes' BMS Isolator board.

Ah, yes good point. I got all excited that it was actually working! I think the next thing is to build up the HV Junction Box and where to fit it.

Re: BMW E46 Coupe Conversion
Another couple of steps forward over the past few days.
Started putting the firmware together for the controller. Can signals up and running and contractor control working.
Just done the first low voltage test run using a 12V battery and starter motor. It works!

Re: NLG513 charger profiles
Yep saw it. I've currently got a 'garage floor' test rig setup with the relay box from my leaf battery in it. The contractors are connected to switches so I can manually bring them in, including the pre-charge relay.
