E46 EV conversion design parameters and engine is out

As of right now I have decided to go for Hyper 9 HV motor with 48S 160Ah LFP. According to AI, this would give around 100km of range. Current battery placement plan is for 20 cell in the engine bay and 14+14 distributed between two sides where the gas tank used to be. This would make the front end lighter compared to original ICE car, also would help in steering effort since the power steering would be deleted.

For wheels, I’m going for style 53 due to the low weight and narrow tires. This should reduce rolling resistance and increase aerodynamic. TPMS will be added to ensure optimum tire pressure.

On to some pictures, Eid break was spent by pulling the engine out and detaching the transmission.

E46 EV conversion started

Our local transport department allow EV conversion to be registered properly for road use. So since I still have the E46 with broken engine, it is the perfect platform for this project. And as I know from years back when starting the project for the E30. The bell housing for the gearbox is the same. I spent the new year break preparing for engine removal.

As of now, the plan is to mate the gearbox with Hyper 9 motor. I’ll keep this blog updated.
