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. L'invention concerne un circuit de commande (100), un ensemble carte de circuit imprimé, et un système parallèle de batterie (200). Le circuit de commande (100) est disposé entre une bat
