Abstract: Provided are a control circuit (100), a circuit board assembly, and a battery (200) parallel system. The control circuit (100) is disposed between a battery (200) and a busbar (300), and the control circuit (100) comprises an acquisition unit (1), a control unit (2), and a current-limiting circuit (3). The control unit (2) is used to start timing when the current of a positive electrode of the battery (200) is greater than a preset threshold, and after the duration of the voltage of the positive electrode of the battery (200) greater than a first preset threshold is greater than a preset time, reduces the current of the positive electrode of the battery (200) by means of controlling the current-limiting circuit (3), until the current of the positive electrode of the battery (200) is less than or equal to the preset threshold.
