I'm building a kitcar with good old petrol engine, but I'm looking ahead to convert it to electric. My idea is to use rear Mitsubishi PHEV motor + dif.
What else would I need? I wanted to make a kind of shop list...
1) rear inverter: this is controlled via CAN bus (I found the CAN messages around, 1 CAN message with torque request + 3-4 others and that's it?
2) charger: someone said this will mate with the inverter, any special CAN message for it?
3) DCDC: Does that go all together with charger and inverter? Is this needed to generate 13.5V? Does it need CAN messages?
4) VCU: is this the board that does all the CAN messages, torque requests, etc?
5) batteries: I'm mostly interested in this one! Which way to go? is it possible to dismantle a full battery pack into cells, rearrange and/or add more cells of same type, put a new BMS and have more power?
Summary: get rear axle + inverter + charger + DCDC + VCU to build a package, get a couple of batteries + rearrange + new BMS to have more KWh.
Or perhaps I'm completely lost

Thanks!
