Abstract: A processor-implemented method to detect a battery fault includes obtaining first states of detection targets in a battery, generating a representative state based on the first states, generating second states by applying the representative state to each of the first states, generating one or more third states by amplifying at least a portion of the second states, and detecting for a fault of the battery based on the one or more third states.

Abstract: A method to control a battery temperature includes: determining state difference information of a first battery, among batteries, based on state information of the first battery and average state information of the batteries; calculating a first output value of a first converter corresponding to the first battery based on the determined state difference information; and controlling a charging and discharging process of the batteries to cause the first converter to generate a power flow based on the calculated first output value.

Abstract: A battery operating apparatus, an auxiliary battery unit, and a battery control method are provided. The battery operating apparatus includes a master battery manager (BM), a fixed battery unit configured to supply a fixed power to a load, the fixed power remaining unchanged over time, and a removable auxiliary battery unit configured to supply a variable power to the load, the variable power varying over time, wherein the master BM is configured to control the fixed battery unit to supply the fixed power among a power needed by the load, and to control the auxiliary battery unit to supply the variable power among the power needed by the load.
