Powered by 990 A123Systems Nanophosphate cells, the KillaCycle set the new world record for the fourth time in two days at the All Harley Drag Racing Association (AHDRA) event at the Firebird Speedway in Chandler, AZ on 31 March 31 2007.
The 165 lb (74.8 kg), 375 V, 7.5 kWh battery pack powers the KillaCycle from 0 to 60 mph in less than 1.5 seconds. The A123Systems Nanophosphate cells are next-generation Automotive Class Lithium-Ion batteries designed for power, safety and life.
The KillaCycle is a great example of how our battery technology enables electric drive automotive applications to experience a new level of battery performance. We look forward to working with Bill Dube’ and his team to continue to push the limits in racing and can offer these same improvements to others within the automotive market.—Jonah Myerberg, senior engineer at A123Systems
Denver CNC designed the custom battery management controls. A Café Electric Z2K Motor Controller converts the battery energy to motive power. The controller can handle currents up to 2,000 amps and 400 volts.
Hi-Torque Electric provides two modified 6.7 inch Model L-91 Advanced DC Motors that pull a direct chain drive to the rear wheel.
According to the KillaCycle team,
The KillaCycle uses about $0.05 worth of electricity for each run down the strip. The bike only uses ~300 W-hr/mile, including the burn-out.
Including burn-outs, the KillaCycle could make 6 or more runs on one charge (not at max performance.)
The pack recharges in as little as 12 minutes. (Limited by charger. Battery can be recharged in 5 minutes.)
