ENERGY STORAGE RESERVOIR

摘要

An energy management system includes an energy storage reservoir (100) and a fluid pump (412). The energy storage reservoir (100) includes a fluid reservoir (104) configured to contain varying quantities of a fluid and to isolate the fluid from the ambient environment. The fluid reservoir (104) has a top surface (112), a bottom surface (116), a flexible member (124), and at least one opening (128) for filling or for emptying the fluid reservoir (104). A pressing mass (108) of solid material is positioned above the fluid reservoir (104) with a weight sufficient to press the fluid reservoir (104) and empty the fluid reservoir (104) of the fluid when the fluid reservoir opening (128) is open. The pressing mass (108) is supported by the fluid reservoir (104) when the fluid reservoir (104) contains fluid and the fluid reservoir (104) is closed. The flexible member (124) is disposed around the fluid reservoir (104) to seal the fluid and to facilitate vertical motion of the pressing mass (108) as the fluid reservoir (104) is filled and emptied. The fluid pump (412) is configured supply fluid to the fluid reservoir (104) via the at least one opening (128).
