Abstract

A wireless security device and method and a battery pack may be provided. The wireless security device comprises: a plurality of antennas associated with a battery management system, BMS; an angle-of-arrival estimator configured to estimate an angle of arrival from a signal received through at least one antenna among the plurality of antennas and calculate a reliability index for the angle of arrival; a beam forming controller configured to calculate a beam forming weight and control a phase and an amplitude of the signal based on the beam forming weight; a channel estimator configured to estimate a channel state of the signal and calculate a channel change rate based on the channel state; and an anomaly detector configured to perform anomaly detection for the signal based on the channel state, the channel change rate, the angle of arrival, and the beam forming weight.
