Vehicle1993 Honda CBR 1000F
MotorHPEVS AC-15 3-Phase AC
ControllerCurtis 1238-7501
Batteries24 CALB/Skyenergy CALB 100AH, 3.20 Volt, Lithium Iron Phosphate
Oh yeah. 7.2 KW of power on board.
System Voltage72 Volts
ChargerDelta-Q Technologies Quiq 72
Fits on board under the gas tank.
DC/DC ConverterVicor V72B12E250BL
Compact, rugged chip design, capable of
putting out 250 watts of power for the 12v
system. Ample for handling the lights and
the 12v requirements of the BMS and
instrumentation.
Top Speed100 MPH (160 KPH)
Estimated 100 mph based on current
gearing. Current batteries are not
capable of pushing the bike to that
speed. Other AC-15s used in racing are
hitting 125+. This bike is being
optimized for range rather than top
speed.
AccelerationThe original motor in the CBR put out 76
ft/lb of torque at 8500 RPM. This motor is
capable of 95 ft/lb of torque. At zero
RPM.
Range75 Miles (120 Kilometers)
Won't know my full limit for a while. It's
getting cold now and I'll have to put a
few cycles on the pack before I can get an
accurate range estimate. Hoping for 70+.
EV Miles
Current:45 Miles (72 Kilometers)
Seating CapacityCapable of two-up, but ridden solo.
Curb Weight500 Pounds (227 Kilograms)
Original wet weight was about 520.
Conversion TimeAbout 100 hours for Phase 1, 150 hours for
Phase 2, mostly spent in fabricating the
battery housing.
Conversion CostApprox $10K including bike, motor,
controller, BMS, and batteries.
Experience? Priceless.
Additional FeaturesMy next steps will be to incorporate the battery display,
the spyglass meter, and a GPS into the dash, replacing the
now non-functional analog gauges.

I also plan to build an interface between the BMS and the
charger to use the high voltage cutoff signal to shut down
the charger.
A total blast to build and fun to ride, too! Can't wait to
get a few cycles on the batteries so I can get the full
benefit of the new lithium pack.

Video of my first ride is here:
