  "textContent": "This application provides a battery assembly and an energy storage system. The battery assembly includes a control unit and a DCDC converter. 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. 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; and/or the control unit is configured to: after a power supply encounters a power failure, control a discharge capability of the battery assembly to be greater than a maximum nominal discharge capability of the battery assembly, and supply power to a first load and a second load by using a DCDC converter; and after the first load is powered off, control the discharge capability of the battery assembly to be restored to the maximum nominal discharge capability, and supply power to the second load by using the DCDC converter. In this way, breakdown of the energy storage system including the battery assembly is avoided.",
