Looks good Mr Bauer!

I was also thinking maybe we could get BT functionality into Johannes' BMS at some point. The TorquePro app looks quite good.

Oh its counting your SOC :D

Coding is still a bit basic, there is no drift for miss counting except at the very top end.
Wonder how close the SimpBMS is to your other system.

I just found out i still have some code from Dimitri that is using BT with Torque pro. If you like you can program your chip with it and try to use torque :).

I use USBASP programmer with AVRDUDE software. There is 6 pin header on the board, I use pogo pins, but you can solder pin header or whatever you want. I use these command lines as example, first one unlocks security bit and sets fuses, second flashes code and locks it

avrdude.exe -F -Cavrdude.conf -v -patmega328p -P usb -c usbasp -e -Ulock:w:0x3F:m -Uefuse:w:0x05:m -Uhfuse:w:0xDA:m -Ulfuse:w:0xFF:m

avrdude.exe -F -Cavrdude.conf -v -patmega328p -P usb -c usbasp -Uflash:w:SOC_Gauge_V4_TQ_450V.hex:i -Ulock:w:0x0F:m

There are two codes in rar file. one is normal AT serial code, the other is TQ code.

Also my board is set to max 350Vdc so i use external 500K trim pot set at 325K and i get correct voltage.

Fabulous article in SpeedHunters magazine 8-)

Converted: The Tesla-Powered BMW 8 Series (here)

When I asked Damien if there was any advice he would give to others who are also interested in going electric, he said this: “This is all stuff that you can do in your shed or at home as safely as wiring a plug or working on a high pressure fuel system. You still get your hands dirty. They’re still cars.”

That's a great quote.

Thanks folks. I'm still in quite a bit of shock about it. The article was originally supposed to appear in Performance BMW magazine but I guess the grinder cut, mig welded mild steel didn't exactly spin their turbine. Having it on Speedhunters feels like winning the lottery:)

The comments offer an interesting insight into the pervasive myths that still surround conversions. "Informed ignorance" I call it. Goes like this :
" I know xxx about ev conversion, therefore I have no reason to test to see if xxx is actually true".
Sort of like an anti scientific method:)

Bit of an eye opener this video!!! Thanks for sharing. Glad to hear we're going to see more of the Panzer soon though, this is the car that started me on my conversion journey, all 113 panzer youtube videos over two weeks (nearly got evicted for it) :D and great to see it in the flesh at the conversion course

Scary stuff! Glad to see it resulted in minimal damage. As you said, very lucky indeed. Looking forward to v2, and how it's put together with the current options available.

Wait you just had them under the car and not enclosed? Must have been corrosion or something into the plug wiring.

Wow, sorry to hear what happened but yes so lucky you were there to catch it, have you considered reconfiguring the ampera pack for additional solar storage?
