A quick update on this project. It's not dead!
Most of last year was spent trying to source a BMS system, which proved to be tricky with the chip shortage. I then spent the first few months of the year testing the BMS system and the charging setup of the Prius Inverter. Using the Prius Inverter to charge from the mains is pretty highly experimental, there are 2 or 3 other people in the world that I know of also trying it. Turns out it's not really that ideal, the setup is far more complicated than using a traditional in car charger and has the potential to short lots of things. Which is what I did, killing my Arduino based VCU in the process. So I decided to switch charging to an Outlander Charger and DC-DC converter. This runs from Canbus and I got it running in a weekend pretty flawlessly.
The BMS system is also being changed out to use Tesla Model s slave boards and an open source BMS system called SIMP BMS that enables communication and control of OEM BMS slave boards.

So allot of months delay but that is the nature of experimenting with new ideas, sometimes they don't go anywhere.

I also decided to change the battery pack location after hearing about the DVLA getting really picky on modifications. If I had to go down the IVA route I would need a certification on my battery box costing around £6,000. So I decided to weld the spare tyre compartment back in and leave the front alone. Instead the battery box will bolt into the passenger seat mounts. Not ideal as it's now a single seater, but that's better than potentially writing the whole project off after it's all finished.

Currently the battery box is installed, all the car wiring is complete. Most of the car is reassembled. Just waiting on a replacement board for the one of Tesla BMS board and then I can complete the High Voltage wiring.
What's left is minor things, brake bleed, suspension refill, bumpers to go back on and a little bit of inverter tuning.
I'm expecting spinning wheels in the next week or so, with MOT shortly after.
