What is a battery state of charge (SOC)?

The Battery State of Charge (SoC) is the ratio of the current charge in the battery to its maximum possible charge. It is like a fuel gauge for batteries. SoC indicates how much charge remains in the battery and is usually displayed as a percentage. For example, 100% means the battery holds a full charge, and 0% is empty.

What does SoC mean on a battery?

SoC indicates how much charge remains in the battery and is usually displayed as a percentage. For example, 100% means the battery holds a full charge, and 0% is empty. SoC can also be shown using voltage levels; a higher voltage indicates a higher SoC. 1. Coulomb Counting Coulomb counting is a common way to measure SoC.

Why is SoC prediction important for EV battery management?

Among all the functions, SOC prediction plays the crucial role. SOC of the battery is defined as the amount of charge present in the battery to its nominal capacity under the same operating environment. Determining battery SOC is critical for EV battery management systems to ensure safe, reliable, and efficient operation 13.

What is SOC in lithium ion batteries?

SOC is a significant parameter of lithium-ion batteries and indicates the charge level of a battery cell to drive an EV 4, 5. SOC estimation of lithium-ion batteries is compulsory for the safe and efficient operation of EVs. An accurate SOC estimation method improves the battery lifespan by controlling overcharge and overdischarge states 6.

Why is SoC important in battery management?

SOC is a critical parameter in battery management, represents the available energy reservoir within a battery, expressed as a percentage. Despite its significance, accurate SOC determination is challenging due to battery complexity influenced by chemistry, temperature, and usage patterns. Traditional SOC Estimation Methods :

How PDAEs based battery electrochemical models are used in battery SoC?

Uses PDAEs based battery electrochemical models to battery SoC. Electrochemical models completely describes the battery reactions that determines the battery charge and discharge behaviours and estimates the battery capacity fading, due to which the SoC estimation results are relatively accurate but involves complex mathematical equations.
