Abstract
A remaining battery life measuring device may include a first estimator configured to estimate a state of charging of a battery using an open circuit voltage of the battery; a second estimator configured to estimate the state of charging of the battery using charge, discharge, or charge and discharge currents of the battery; a correction unit configured to generate a correction value on the state of charging estimated by the second estimator, based on the state of charging estimated by the first estimator or an output state of charging; and/or a state of charging (SOC) processing unit configured to calculate the output state of charging using the state of charging estimated by the second estimator and an accumulated correction value. The accumulated correction value may be generated based on the correction value.
