Abstract: Example backup power boxes and control methods for the backup power boxes are described. In one example method, a backup power box includes a plurality of backup power ports, a multiphase wire, a plurality of relays, a first switch circuit, and a controller. The controller controls the self-locking circuit to output a control signal that controls the first switching transistor to switch to a turn-on state. When the first switching transistor is in the turn-on state and the controller is incapable of controlling the self-locking circuit to output the control signal, the self-locking circuit continuously outputs the control signal to maintain the first switching transistor in the turn-on state.
