ENGINE MANAGEMENT FOR HYBRID ELECTRIC VEHICLES
A hybrid electric vehicle comprising an internal combustion engine and a battery bank as sources of power is being investigated. In this study, the conversion of mechanical work from the engine to electrical power using an alternator and phase converter is investigated. The unique characteristics of the three components above are analyzed to identify the corresponding limitations. More importantly, the favorable range of operation of these units operating together is identified.
An experimental van using the hybrid concept is constructed and its starting and control modes are described. An analysis of engine, alternator and converter is performed to formulate a control strategy. Special attention is given to the converter and its algorithm due to its important interface role between the alternator and battery bank.
