This paper proposes a residual capacity estimator with higher accuracy for lead-acid batteries. The calculation method is using different discharge capacity rate of a battery in different discharge current to calculate state of charge. Therefore, curve fitting state of charge estimation has the ability of revising value of state of charge with the changing of lode, and this improves Coulomb state...
