  • HYDRAULIC ENERGY ACCUMULATOR
    Publication number: 20110041490
    Abstract: Example energy storage systems (20, 20?, 20?) comprises a fluid circuit (22, 22?, 22?) and an electrical unit (24, 24?, 24?) configured to operate as a motor in a first phase of operation and to operate as a generator in a second phase of operation. The fluid circuit (22, 22?, 22?) comprises a first fluid container (30, 30?, 30?) situated so content of the first fluid container experiences a first pressure level; a tank (32, 32?, 32?) having its content at a second pressure level (the second pressure level being less than the first pressure level): and, a first hydraulic motor/pump unit (34, 134, 34?) connected to communicate a first working fluid between the tank and the first fluid container. In the first phase of operation electricity is supplied to the first hydraulic/motor unit (34, 134, 34?) whereby the first hydraulic/motor unit transmits the first working fluid from the tank into the first fluid container (30, 30?, 30?).
