Abstract:

Energy Saving and New Energy Vehicle Technology Route (version 2.0) puts forward new requirements for vehicle energy saving technology. Traditional vehicles with internal combustion engine (ICE) can only add secondary energy storage devices to recovery of part of braking energy. The Ragone diagramm shows that flywheel energy storage (FES) has many merits such as higher power density, higher efficiency, fast response, environmental-friendly performance and long cycling using life, which becomes an ideal secondary energy storage technology for traditional ICE vehicles. Despite some progress, there is no systematical review on the recent progress of flywheel energy storage system in the automotive industry. The FES is retrieved based on CNKI database, Engineering Village database and Web of Science database, and highlights on the analysis of application of FES technology in the automotive industry. Comprehensive databases show that FES technology has been exploring in the past twenty years. For two typical hybrid electric and mechanical energy storage and power delivery system, the exploration, research and verification process of the hybrid mechanical energy storage and power delivery system in vehicles is emphatically introduced. Meanwhile, the researches elaborate on the basic structure, characteristics, research status and development trend of this system. The comprehensive analyses show that the mechanical hybrid delivery system, through the pure mechanical connection between the flywheel and vehicle powertrain, not only solves the problem of insufficient power and energy-saving effect caused by the power limitation of the electric drive system, but also improves the energy conversion efficiency of the flywheel hybrid powertrain.
