Vehicle | Still looking for a donor vehicle for the wheels & suspension. The front wheel & suspension of a full-size motorcycle stack up too high for good visibility with a low rider position so I'm looking into scooters and subscale motorcycles |
Motor | Perm Motor PMG-132 Permanent Magnet DC |
Drivetrain | Preferably a belt, but a chain will do, and the width is in a critical spot. |
Controller | Alltrax AXE 4865 650 Amp, 24-48 V |
Batteries | 160, 48.00 Volt, Lithium-Ion 16s10p 2.2Ahr, 3.6V cells from disassembled DeWalt 36V batteries, unless I can get the cells directly from them. I'll probably have a separate 12v Li-Ion battery for accessories so I can distribute the battery weight and avoid a DC/DC converter. |
System Voltage | 48 Volts |
Charger | Soneil 48V |
Heater | probably just garage pre-heat |
Instrumentation | real-time bar graphs of each cell voltage, combined with overvoltage protection and cell balancing. Design done and prototype parts on order... |
Top Speed | 85 MPH (136 KPH) |
Acceleration | projected, 0 to 60 MPH in 6.5 Seconds. Using series/parallel dual ETEKs is tempting |
Range | 48 Miles (77 Kilometers) projected, Assuming 20 Ahrs of batteries, which is all I would need for my commute. There's room for more, though. |
Watt Hours/Mile | 30 Wh/Mile projected, The plan is to use a fully enclosed fairing to make this the world's most energy efficient commuter vehicle. The world's fastest human powered vehicle (varna diablo) has achieved 80 mph on about 450 watts using a very compact aerodynamic fairing. I'm shooting for about 1600 battery output watts at that speed. |
Seating Capacity | 1 adult |
Curb Weight | 230 Pounds (104 Kilograms) Motor, batteries and controller will be about 70. Hoping for about 160 lbs for the rest. |
Conversion Time | probably 300 hrs planning in the last 5 months so far. Still to go: about 1.5-2 years of evenings and weekends |
Conversion Cost | estimating about $10k |
Additional Features | F1-style composite safety cell for the rider. 5-poit racing harness 21" step-over sill to get in. Spring-loaded doors for feet. Winglets enclose the rear view mirrors, headlights, and turn signals. |
