Abstract: This paper presents a novel power management scheme to achieve high performance and cost reduction in an electric vehicle for short profile fleet application. The measured drive cycle of an internal combustion engine meter-reading vehicle has been analyzed for the optimization of the EV system design and power management. Zinc Bromine batteries will be employed to provide the continuous power for normal driving while ultracapacitors will be employed to provide peak power demand during acceleration and to take regenerative braking energy efficiently during deceleration. The EV motor operates in constant torque mode at motor speeds below the base speed and in constant power mode at motor speeds over the base speed for high efficiency and low cost.
