Abstract
After an initial capacity setter (,) sets the initial residual capacity immediately after the application of power as 100%, a full-charge voltage corrector (,) sets the full-charge voltage as the estimation voltage Vn,of a battery (,) immediately after a load change, this full-charge voltage Vno being used to determine the residual capacity SOC immediately after the change. After charging is interrupted midway, if the load is changed, a full-charge voltage estimator estimates the full-charge voltage responsive to the estimation voltage immediately after the load change, this estimated full-charge voltage being used to determine the residual capacity.
