State of Charge (SOC) definition

State of Charge (SOC) means the available electrical charge in a REESS expressed as a percentage of its rated capacity.

State of Charge (SOC) means the available electrical charge in a tested device expressed as a percentage of its rated capacity.

State of Charge (SOC) means the density ratio of hydrogen in the CHSS between the actual CHSS condition and that at NWP with the CHSS equilibrated to 15 °C. SOC is expressed as a percentage using the formula:

Examples of State of Charge (SOC) in a sentence

• Adjust the State of Charge (SOC) with discharge to [50 %] before starting the vibration test profile.

• The following test can be conducted with the RESS [or with module(s)] of the RESS.[If tests are performed on module basis, evidence shall be provided that the results are representative for RESS.]Adjust the State of Charge (SOC) with discharge to [50 %] before starting the vibration test profile.

• The "State of Charge" (SOC) is commonly defined as the instantaneous ratio of electric quantity of energy stored in a device (compare also definitions in UN Global Technical Regulation No. 20 and UN Regulation No. 100).

• State of Charge (SOC) for the REESS testing: At the preparation of the test, the SOC shall be adjusted to a value in the upper 50% of the normal operating SOC range for the tests for which the change of SOC is not aimed.

• For vehicles operable in "RESS only mode." verify the RESS is at 100% SOC in accordance with the requirements of ETA-TP08, “RESS Charging Procedure.” For vehicles operable in "normal operation mode," verify the RESS is at an Initial State of Charge (SOC) achieved by operating the vehicle for at least 5 miles (8 kilometers) at a constant speed of 35 mph (56 kph).

• The technical standards should have only a limited and guiding role in a reformed planning system that will allow greater flexibility and adaptability to local situations and demand.

• The battery shall be capable of being recharged to 90% State of Charge (SOC) from the fully discharged condition (1.75V/cell) within 8 hrs.

• If tests are performed on module basis, evidence shall be provided that the results are representative for RESS.] Adjust the State of Charge (SOC) with discharge to [50 %] before starting the vibration test profile.The RESS shall be applied to the shock levels and durations described in Table 5 and 6 in both positive and negative directions.

• While the rated power of a combustion engine is a well-known and determinable parameter, the hybrid systems power can differ with test time depending on parameters like Rechargeable Electric Energy Storage System (REESS) size, peak power capability, State of Charge (SOC) level, thermal restrictions of components and so on.

• For a specific pattern of State of Charge (SOC) (vector X), equivalent half or full cycles can be found, and an equivalent degradation cost can be obtained with the equation:f cyc(X) = Ccyc(dj) = ∑ Lj Cini dkp (16)j∈Ωn100 j where Ω is the set of DoDs at which each cycle occurs and Cini is the initial cost of the battery.
