Calculation device calculating available capacity of secondary battery and method of calculating the same |
摘要 |
A method of calculating an available capacity includes the steps of: calculating a first estimated SOC from a value in voltage; calculating an integral of a value of a current and adding the integral to calculate a second estimated SOC; calculating a difference between the first and second estimated SOCs; calculating a first correction coefficient R( 1 ) from the value in voltage; calculating a second correction coefficient R( 2 ) to be smaller for the current having a smaller value; and adding the second estimated SOC to an correction term, or the dSOC multiplied by R( 1 ) and R( 2 ), to calculate a corrected SOC.
