The preliminary results of simulated electric vehicle chopper controlled discharge of a nickel/zinc (NiZn) battery show delivered energy increases of 5 to 25 percent compared to constant current discharges of the same average current. The percentage-increase was a function of chopper frequency, the ratio of peak-to-average current, and the magnitude of the discharge current. Because the chopper effects are of a complex nature, electric vehicle battery/speed controller interaction must be carefully considered in vehicle design to optimize battery performance.
