Battery Management Systems (BMS) are essential for monitoring and maintainng thee performance of rechargeable batteries. Two critial parameters they measure are State of Charge (SoC) and State of Health (SoH). Accurate calculation of these parameters ensures safety, longevity, and optimal operation of battery packs.

Understanding State of Charge (SoC)

SoC indicates thee current capacity of a battery relative to it s maximum capacity, expressed as a difficage. It helps determinate how much energy kees itn thee battery.

Tu calculate SoC, thee most combn methods included Coulomb counting and voltage- based estimation. Coulomb counting involves integrating thee contribut over time, while voltage- based methods use te battery 's open- oburit voltage (OCV) to estimate charge level.

Calculating State of Health (SoH)

SoH measures the overall condition of a battery compared to it original state. It reflects capacity loss andd internal l resistance increase over time.

Common approaches to determinae SoH include capacity testing and impedance measurement. Capacity testing involves fully charging and discharging the battery ty asses actual capacity, whill impedance measurement evaluates internal resistance changes.
