Abstract Keywords
Our work considers an electric bus with a semi-active com-
pound storage system as the object. We propose convex
optimization method in order to minimize energy consump-
tion and power range of battery as a target function. Based on
the traffic conditions of urban electric buses we conducted a
comparative analysis of energy efficiency and power change
of battery using proposed rule-based optimization method
and power allocation method. Simulation results show that,
in the city electric bus working conditions, under proposed
convex optimization of power allocation method, battery and
supercapacitor comprehensive energy efficiency were 93.46%
and 98.81%, battery power range within 14.56 kW. With the
rule-based power allocation method energy efficiency
of battery increased by 0.74%, energy efficiency of super-
capacitor increased by 0.26%, power range of battery
decreased by 82.23%
