charge energy: the amount of primary energy crossing the test boundary during the charge interval. charge inten,al: the time duration during which the charging process operates.
charge loss rate: the change of the state of charge during a standby interval, expressed as kilowatt-hours per hour. charge power: the rate at which charge energy crosses the test boundary; the charge energy divided by the charge interval. charge power rating: a charge power designated in a test plan (such as maximum, minimum, nominal, or guaranteed) that may be derived from contracts, specifications, nameplates, guarantees, or other sources.
charge process: the means by which primary energy is transformed into increased internal energy of the storage medium. charge start-up interval: the time duration of transition from the standby state to the charge power rating. discharge depth: a fraction or percentage equal to 1 minus the minimum state of charge at which the ESS can operate, which may be qualified as maxim um, rated, normal, or guaranteed, and/or be referenced to the discharge power rating. discharge energy: the amount of primary energy crossing the test boundary during a discharge interval. discharge inerval: the time duration during which the discharge process operates.
discharge power: the rate at which discharge energy crosses the test boundary; the discharge energy divided by the discharge interval.
dischar,qepowerrotin,q: a discharge power indicated in a test plan (maximum, minimum, nominal, guaranteed. etc.), which may be derived from contracts, specifications, nameplates. guarantees. or other sources.
discha rge process: the means by which internal energy of the storage medium is decreased and transformed Into primary energy.
discharge start-up interval: the time duration of the transition from the standby state to the discharge power rating. energy loss: the amount of energy leaving the test boundary from the storage container, which decreases the internal energy of the storage medium.
energy storage system (ESS): a system that consumes primary energy to increase the internal energy of a storage medium and releases the stored energy at a later time as primary energy.
exhaust energy: the amount of nonprimary energy leaving the test boundary of the ESS during the charge interval or discharge interval.
fuel energy: the amount of energy crossing the test boundary during a storage cycle in the form of combustible mass, i.e.. the fuel rate multiplied by the higher heating value.
fuel heat rate: the fuel energy divided by the discharge energy during a storage cycle, expressed as British thermal units per kilowatt-hour (kilooules per kilowatt-hour).
fuel rate: for solid and liquid fuels, the mass of fuel fired per unit of output. For gaseous fuels, it is defined as cubic feet ofgas at 59°F and 14.696 psia (cubic meters at 15°C and 101.325 kPa) per unit of output. Fuel rates should be qualified by reference to the unit of output.ASME PTC 53 pdf download.
