Abstract

Embodiments of the present invention relate to a battery control device (12) and a short-circuit detection method thereof. The battery control device (12) may include: a first battery control unit connected between an external load (20) and a first battery module (11) and configured to control an electrical connection between the external load (20) and the first battery module (11). The first battery control unit may include: a first switch (SW11) electrically connected between a positive terminal (B+) of the first battery module (11) and the external load (20), a second switch (SW12) electrically connected between a negative terminal (B-) of the first battery module (11) and the external load (20), and a first controller (121) configured to control opening/closing of the first (SW11) and second switches (SW12). The first controller (121) may detect a short-circuit accident between the external load (20) and the first battery control unit, according to a voltage between both ends of the first switch (SW11) detected when the second switch (SW12) is in a closed state and the first switch (SW11) is in an opened state.
