So some of you might already know about my E31 conversion as it's been going on 3 years now! Currently running a Siemens 1pv5135 motor and DIY inverter and 6 speed manual gearbox. Has been running very well the last few months but with the Tesla components becoming available and my work on the open source control boards progressing nicely I've decided to convert the E31. Again.

I had originally thought to use the small high efficiency drive unit but decided to go all in and put in the Large rear unit for 450hp+ :D

Going to be getting some help and the use of a workshop and vehicle lift for the drive unit install as it will need some serious work done to the rear subframe and boot floor. Once the drive unit is in then I can start putting some batteries into that nice big empty engine compartment. Should make quite a fun car and test bed for the open source control board. Stay tuned:)

that is going to give you plenty of Kw, but not alot of KwH.

You planning on using multiple packs?

You ofcourse forgot to mention all of this testing is being done on closed race course. :D

Any plots of what the battery sags to?

It is starting too look real good.
Great update on Patreon (here) :D

"That one pull bent a grade 8 12mm bolt about 10 degrees in the front motor mount."
So, some news. On the 18th June I'm taking the Panzer to a track day at Mondello Park.

The organisers of the event are providing me with 3 phase power for charging so if this doesn't blow the drive unit nothing will:)


My plan is to use it as tuning session to dial in the parameters for different driving styles and requirements and of course post these on Github for people to use.



there will be lots of video and maybe even a live stream or two:)

How you going to be switching that three phase? Got a contactor or are you going to use the switch and serial monitor? :)
Big charge point :)
Lots of stuff to get done. 30 days and counting :

Need to find a tyre sponsor:)
Please do take some logs then :)

Wondering what the 'Thermal Power Limits' do, specifically will the modules back off them shelves when they get hot.
