The Ampere-hour counting method, called Coulomb counting, calculates the state of charge (SOC) by integrating the battery current over time. It measures the total charge that flows into or out of the battery, considering the current direction, and accumulates it over a specific time interval.
The algorithm was validated by charging/discharging a lithium-ion battery through fifty complete cycles and evaluating the error in the estimated state of charge. The result shows a mean absolute error of 0.35% in the estimated state of charge during the test.
A data-driven coulomb counting method is proposed to estimate state of charge (SOC) of lithium-ion battery. The incremental capacity analysis method without filtering process is applied to calibrate the initial SOC value. The Gaussian process regression (GPR) method is used to calibrate the actual capacity.
To estimate the battery SOC by the Ah counting strategy, the cumulative charging capacity and cumulative discharging capacity during charging or discharging are calculated according to the battery charging and discharging conditions, and then the increase and decrease of SOC during the process are calculated.
