What is SoC & how does it affect battery performance?

As the SoC is one of the most important states to be known to optimise the battery performance and extend the lifetime of batteries, several SoC estimation approaches has been reported in the literature .

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.

What is SOC in battery management?

SoC is defined as the rate of the remaining percentage of battery capacity. The monitoring and regulation of the states of batteries are management. It includes, among others, algorithms to determine the battery’s more critical states.

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

Understanding State of Charge (SOC) : 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.

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 are battery state space model based SoC estimation techniques?

The battery state space model based SoC estimation techniques are being developed considering the online estimation of battery SoC such as KF, EKF, UKF and EnKF and H-infinity SoC estimation approaches.
