The invention relates to the technical field of electric vehicle integrated controllers, and discloses an integrated control circuit, an integrated control assembly and an electric vehicle, the integrated control circuit comprises a low-voltage storage battery, an integrated controller and a power battery, and the integrated controller comprises a DC/DC converter and a driving motor controller; a B + binding post of the low-voltage storage battery is connected with the DC/DC converter through a B + cable, the DC/DC converter is connected with the driving motor controller, and the power battery is connected with the integrated controller. Therefore, when the power supply of the low-voltage connector is lost and the main contactor is disconnected due to the collision of the vehicle, the driving motor controller is backed up through the existing low-voltage storage battery based on the B + cable without the help of an additional high-low voltage backup power supply, so that the safe operation is realized.
