While I applaud these efforts to create a repairable EV, I believe there is a better way. I would like to see an electric motor assembly that is somewhat tubular, small enough to occupy the driveshaft hump of any rear wheel/differential driven car. The motor body can be long enough to contain as many electric motors in a line as needed for good to excellent performance, all turning the same shaft. If these motors are all turning a splined shaft, any single motor could be replaced easily (cheaply) if it ever fails. The rear of the motor would mate directly to the differential, using adapter plates specific to that car. The motor shaft connects to the differential pinion gear with a conventional U-joint.The front end of this tubular motor assembly would be attached to the car frame in a conventional supporting assembly, designed to carry the motor torque and mass. Front wheel drive cars could also be converted, although the drive axles would simply mate into a motor assembly that replaces the current engine/transmission. In many cases, the existing transmission case shell might be reworked (by CAD/CAM processes) to accept electric motors, as many as needed for acceptable performance. One Lynch pancake motor for each front wheel might do the job, but better motors may be available by now. Discard the ICE, transmission, clutch, and driveshaft. Retain the radiator, only if the new motor assembly needs liquid coolant. A coolant pump would be added, then. Add battery banks and their attendant electrical controls. The bottom line here is a "universal" electric power system to fit almost any compact car, using a minimum of added hardware. I can imagine commercial chains of "conversion shops" doing this work for any customer who comes in with a suitable rolling chassis. The economies of scale would keep the conversion costs low. Any rolling chassis could then become an EV, with no extra bodywork or crash testing needed. Most commuter cars with a blown ICE or wrecked transmission are essentially worthless to the owner now. Just a thought . . . 😎
