Mathematical modelling of a hydraulic accumulator for hydraulic hybrid drives
Mathematical and Computer Modelling of Dynamical Systems, 2016 ABSTRACTHydraulic accumulators are used as energy storages in a wide area of applications. In particular, in automotive hybrid drive-trains, this type of energy storage is an interesting alternative to today’s common strategies like chemical batteries or flywheels.
