The impact of SOC on flow battery efficiency

How does a battery affect the accuracy of SOC estimation?

As a battery ages and its SoH decreases, the accuracy of SoC estimation can be affected. This is because the battery’s capacity and voltage characteristics change over time. Capacity fade: As the maximum capacity decreases, the same amount of charge represents a higher percentage of the total capacity, leading to SoC overestimation.

What is state of charge (SOC) in battery management?

State of Charge (SoC) is a critical parameter in battery management that describes the current charge level of a battery relative to its maximum capacity. It provides valuable insights into the available energy and performance of the battery at a given point in time.

What does SoC mean in a battery?

The percentage of a battery’s maximum possible capacity that remains is known as its state of charge or SOC. Battery SOC performs a function akin to that of a gasoline-powered vehicle’s fuel gauge, indicating the remaining energy in a battery that powers an electric vehicle.

What are the performance measures of a redox flow battery?

These performance measures include State of Charge (SoC), various efficiencies, and energy density. Efficiencies covered herein were Coulomb, energy and voltage efficiencies. Energy density of the redox flow battery is examined in substantial detail to let the reader understand some of the intricacies of evaluating this important measure.
