Abstract: An electronic device according to various embodiments comprises: a UWB communication circuit including at least one antenna for acquiring signals from an external electronic device; a processor operatively connected with the UWB communications circuit; and memory operatively connected with the processor. The memory may store one or more instructions which, when executed, cause the processor to: obtain at least one signal from the at least one antenna; determine a phase-difference-of-arrival of the at least one signal; obtain information related to the state of the electronic device; obtain a calibration value corresponding to the obtained state information of the electronic device from the memory; and determine the angle-of-arrival of the signal on the basis of the phase-difference-of-arrival of the signal and the calibration value.

Abstract: A power generation voltage of an alternator capable of supplying a charging current to a battery is boosted (Step 104). A determination is then made as to whether or not a condition in which the charging current supplied to the battery equals or exceeds a predetermined threshold has been established continuously for a predetermined time after the power generation voltage of the alternator is boosted (Step 112). The battery is determined to be in a low state of charge condition, in which a state of charge of the battery is equal to or smaller than a predetermined state of charge, when it is determined that the condition in which the battery charging current equals or exceeds the predetermined threshold has been established continuously for the predetermined time (Step 114).
