  "textContent": "The present application discloses a device, method, apparatus and medium for short-circuit detection of a switching device and an uninterruptible power supply, for performing a short-circuit detection of a switching device connected between a positive electrode and a negative electrode of a battery within the uninterruptible power supply, so as to avoid failures in the uninterruptible power supply due to short-circuit of the switching device and to improve the reliability of the uninterruptible power supply. The uninterruptible power supply includes: a rectifying module connected between mains electricity and a busbar and comprising a first rectifying sub-module and a second rectifying sub-module, a battery, and a charge-discharge module connected between the battery and the busbar and comprising at least: a first switching device connected between the positive and negative electrodes of the battery, and a second switching device connected between the negative electrode of the battery and a negative electrode of the busbar; the positive electrode of the battery is connected with respective alternating-current ports of the first rectifying sub-module via relays, the negative electrode of the battery is connected with respective alternating-current ports of the second rectifying sub-module via relays; and a capacitor is connected between the positive and negative electrodes of the battery.",
