Hi All,
I just wanted to create a thread for my upcoming project. I hope to modify a VX220 (Opel Speedster) using a Tesla SDU, with a focus on light weight, fun, and open source where possible.
The parts I currently intend to use:
- Vauxhall VX220 2.2L NA
- Tesla SDU
- Openinverter Tesla SDU controller
- LG Chem 16S packs (96s2p total)
- 6.6kW 400V+ charger with CAN (brand undecided)
- DIY central controller to link together inverter, charger, BMS slaves, EVSE, and OEM Vauxhall gauges
- Appropriate replacements to power the cabin heating system and brake assist / ABS.
I have obtained the car, and fingers crossed, the Tesla SDU will fit. I will be getting professional assistance with the mechanical fitment, as my expertise is with electronics rather than mechanics, but hopefully I will be learning the latter as I go along.
I hope to program my own controller to link everything together, using CAN where possible. My main question for now is about how I will integrate the battery modules (whether I can use the LG OEM BMS slave modules, or whether I'll have to replace them). I hope to update this thread as I progress in the coming weeks (months?!).
Any advice on the general setup would be welcome, and any information about the LG Chem BMS slave protocol would be greatly appreciated.
