    Abstract: The present disclosure discloses an integrated controller, an electric drive assembly, and a vehicle. The integrated controller includes: a box; a control unit and a charging/discharging conversion unit that are arranged in the box; and a high-voltage interface assembly, including a high-voltage interface arranged on the box and a high-voltage connection member arranged in the box, the high-voltage connection member being connected with the high-voltage interface, the control unit, and the charging/discharging conversion unit to receive and distribute a high-voltage battery signal. The integrated controller may cancel arrangement of a high-voltage distribution box, which reduces a demand for a high-voltage wiring harness, reduces costs, and saves vehicle space.
