Constant pressure hydraulic energy storage through a variable area piston hydraulic accumulator
Applied Energy, 2013Abstract Hydraulic accumulators are used in a variety of applications to minimize the pressure variation in hydraulic circuits and to store energy. Conventional hydraulic accumulators suffer from two major limitations, the hydraulic system pressure varies with the quantity of energy stored and the energy density is significantly lower than other ...

Influence of Hydraulic Accumulator Performance on the Hydraulic Hybrid Powertrain
ASME/BATH 2019 Symposium on Fluid Power and Motion Control, 2019Abstract Owing to its high power density, hydraulic hybrid is considered as an effective approach to reducing the fuel consumption of heavy duty vehicles. A gas-charged hydraulic accumulator serves as the power buffer, storing and releasing hydraulic power through gas.
