Abstract

A composite energy management algorithm for extended-range electric bicycles was established on the basis of traditional constant power and tracking power control strategies. With the calculation results of driving power demand and state of charge (SOC) value of battery, the algorithm can optimize the start-stop and the specific operating point of the range extender, improving the entire fuel efficiency and keeping the right SOC level of battery. A dynamic model of extended-range electric bicycle was also built with AVL CRUISE. The driving conditions of extended-range electric bicycle with the proposed energy management algorithm were then simulated and analysed. The results show that the range extender can be reasonably started and stopped according to the current SOC level of battery, and the operating point of range extender can be always maintained in the relative higher-efficiency region once started. In addition, the SOC of battery in the simulation always changes as expected of light charging and discharging. This will protect the battery as much as possible and help to prepare for the next power grid charging.
