This means the hardware I will probably want to electrify my service van will become readily available. It’s curb weight is 6200 pounds. I bet at least 2000 pounds come off when I remove the engine, transmission, cooling system, and fuel tank. I have a two ton problem.
How far, how fast? 20 mile (32 km) maximum radius. Most trips are less than 5 km. 55 mph (90 km/h) would be nice, but I could certainly live with 45 mph (70 km/h). Though again, the maximum speed for most trips would be under 60 km/h, and not for the entire trip.
I’m leaning towards a three motor configuration. One to drive the rear axle, and one for each of the front wheels. I don’t need four wheel drive, that’s just a side effect. Whatever my total power requirements (P) are, I think it will be easier (and probably cheaper) to split that total needed between the two front drive motors (P/4) and rear drives (P/2) with smaller motors. One big motor of power output P might be too hard to get.
I’ll have the volume of space formerly occupied by engine/fuel tank/other stuff available for battery storage. Little concerned about how to power the steering and braking systems.
A lot of problems to solve. But, I have the luxury of time.
