Looking at converting an '03 325 to all-electric, but there are some technical problems I can not figure out.
I'll be using a 350 VAC electric motor with 530nM torque, so a tranny is not needed. The motor would essentially go where the tranny used to be.
I do however, need to gear down the rear-end to around 9:1 or 10:1. Where in the world would I get parts to do this?
Eliminating the tranny means I lose my parking pawl and speedo. How can I fabricate a decent parking brake? Standard parking brakes these days are no good. I need to provide something that'll hold the car on a hill.
And where to put the speedo cable? On the bouncing driveshaft? Where to get gears for it? What is its ratio?
Does anyone know exactly how the overdrive works? On my Jeep, overdrive is an add-on module at the back of the tranny, and it would be nice to have overdrive on the electric motor. Does it require pressurized hydraulic fluid to operate? Exactly how does it work? My '99 Jeep's OD is electronically controlled. I wonder if the newest OD units need pressurized hydraulic fluid?
{sigh} no one ever said it'd be easy...
