ABSTRACT:
The method of calculating rechargeable battery charge capacity of this invention has steps to temporarily interrupt charging and calculate battery internal impedance, to calculate a no-load battery voltage by subtracting the product of internal impedance and charging current from the battery voltage when charging current is supplied, to calculate charging power by multiplying no-load voltage and charging current, and to repeatedly perform the charging power calculation integrating that charging power result to compute battery charge capacity.
