1. A battery assembly, comprising:
a control unit; and
a DCDC converter, wherein
the control unit is configured to: when a first load is short-circuited in a process in which the battery assembly supplies power to the first load, control the DCDC converter to output a first current; and
the first current is greater than a maximum nominal discharge current of the battery assembly, is used to break an electrical connection between the first load and a busbar, and is less than a short-circuit protection current of the battery assembly; the maximum nominal discharge current of the battery assembly is a maximum current allowed when the battery assembly is normally discharged; and the short-circuit protection current of the battery assembly is a current that can be used to break an electrical connection between the battery assembly and the busbar.
