Abstract :
This paper presents a new power flow control strategy for a variable speed engine-generator based series hybrid electric vehicle. The specific fuel consumption map of the internal combustion engine (ICE) has been obtained by off-line experiments to achieve optimal fuel efficiency. The proposed power flow controller makes it possible that the ICE operates at its optimal fuel efficiency points without degrading desired dynamic performance. Experimental results of the actual vehicle test as well as the laboratory based load test are shown to verify the proposed power flow control strategy.
