Abstract
A battery temperature estimating apparatus, the apparatus includes an alternating current (AC) power supply configured to apply AC power to a battery; a phase difference measurer configured to measure a phase difference between an AC current and an AC voltage of the battery; and an internal temperature estimator configured to estimate an internal temperature of the battery based on the measured phase difference and a state of charge (SoC) of the battery.
