Free QuoteState of Charge (SOC) is a fundamental parameter that measures the energy level of a battery or an energy storage system. It is expressed as a percentage, indicating the proportion of a battery's total capacity that is currently available to carry out the required function.
SOC is monitored and managed by the Energy Management System. For example, if a battery has an SOC of 80%, it means that 80% of its total energy capacity remains available for use. Conversely, an SOC of 20% implies that 80% of the energy has already been consumed, leaving only 20% of the capacity remaining.
In this blog, we will explore these critical aspects of energy storage, shedding light on their significance and how they impact the performance and longevity of batteries and other storage systems. State of Charge (SOC) is a fundamental parameter that measures the energy level of a battery or an energy storage system.
SOC is a crucial metric because it helps users determine when to charge or discharge a battery. SOC is monitored and managed by the Energy Management System. For example, if a battery has an SOC of 80%, it means that 80% of its total energy capacity remains available for use.
2. Depth of Discharge (DOD) Depth of Discharge (DOD) is another essential parameter in energy storage. It represents the percentage of a battery's total capacity that has been used in a given cycle. For instance, if you discharge a battery from 80% SOC to 70%, the DOD for that cycle is 10%.
The SOC identification results of the reference battery are used to estimate the ∆SOCi, ∆Ri and the CDi max.
