  • Method for estimating depth of discharge of battery
    Patent number: 11899072
    Abstract: A method for estimating DoD of a battery includes obtaining voltage Va at a first electric charge rate A(Ia) and voltage Vb at a second electric charge rate B(Ib) by checking a voltage-DoD table based on DoD of an experimental battery respectively; measuring voltage V of the experimental battery; substituting Ia, Ib, Va, Vb and V into an expression to calculate an estimated current lest; and using a Coulomb counter to update the voltage-DoD table and estimate the DoD of the experimental battery.
