State of Charge definition

State of Charge means the operating parameter that represents the quantity of physical energy stored (measured in units of megawatt-hours) in an Energy Storage Resource Model Participant in proportion to its maximum State of Charge capability. State of Charge is quantified as defined in the PJM Manuals.
State of Charge. (SOC) means the available electrical charge in a REESS expressed as a percentage of its rated capacity.

Examples of State of Charge in a sentence

  • Because the battery with a limited storage capacity is fully charged after a long period with high frequencies and vice versa, there is a need of control algorithm to keep the State of Charge within certain limits.

  • The BMS monitors the battery, ensures a safe and correct functionality, calculates the actual State of Charge (SoC) and State of Health (SoH) and balances the SoC of the single units [1].

  • Wolstenholme, Conductance measurements in Relation to Battery State of Charge from the proceedings of Intelec 1999, section 18-3.

  • After every updated measurement, it sends the current data to the CAN queue and updates the BPS’s State of Charge.

  • Since the BESS can be fully charged or dis- charged after a short period, there is a need for control algorithms to keep the State of Charge (SoC) in between certain limits to guarantee the full availability for primary frequency control [4],[5],[6].1.2 Related Work‌Different possible applications for battery energy storage systems are analyzed in [2].
