Abstract

본 발명은 2차 전지의 충전량을 충전 전력으로서 정확하게 산출하기 위한 것이다. 본 발명은 2차 전지의 충전량을 산출하기 위한 방법이며, 먼저 2차 전지 B로의 충전 전류의 공급을 중단해서 2차 전지 B의 내부 임피던스 R을 산출한다. 그리고, 2차 전지 R로의 충전 전류의 공급시의 전지 전압으로부터 내부 임피던스 R가 충전 전류 Ic와의 적을 감산해서 무부하 전압 Vo를 산출한다. 이 무부하 전압 Vo와 충전 전류 Ic와를 승산해서 충전 전력 W를 산출한다. 이렇게 해서 산출된 충전 전력 W를 산출하므로써, 2차 전지의 충전량 Wsum을 산출하는 것이다.The present invention is for accurately calculating the charge amount of a secondary battery as charging power. The present invention is a method for calculating the charge amount of a secondary battery, and first, the supply of charge current to the secondary battery B is stopped to calculate the internal impedance R of the secondary battery B. The internal impedance R subtracts the product of the charging current Ic from the battery voltage at the time of supply of the charging current to the secondary battery R to calculate the no-load voltage Vo. The charging power W is calculated by multiplying the no-load voltage Vo and the charging current Ic. The charging amount Wsum of the secondary battery is calculated by calculating the calculated charging power W.
