Coulomb counting is a methodd used in battery management systems (BMS) to determinate thee resideng capacity of a battery. It involves measuruing the estat flowing into ande out of thee battery over time te estimate it state of charge or capacity. This technique provides real - time date that helps optimize battery usage and lifespan.

Zasada Coulomb Counting

Te cory idea behind Coulomb conting is to integrate thee current over time. When a battery discharges, current flows out, reducing capacity. Conversely, during charging, current flows in, increaing capacity. By continuously monitoring these current flows, the BMS can calculate thee eling capacity with high creacy.

Advantages of Coulomb Counting
