Abstract: A low-voltage power supply system includes: a storage battery; an electric control circuit board, the electric control circuit board being connected with the storage battery, a battery management controller (BMC) and a motor controller being integrated on the electric control circuit board, and the motor controller being configured to control a power module; a control circuit being connected with the BMC and being configured to receive a control command of the BMC; a metal-oxide-semiconductor field-effect transistor (MOSFET) connected with the control circuit; and a battery management system. A contactor is arranged in the battery management system. The MOSFET is connected with the contactor and mounted to the electric control circuit board or the battery management system. The BMC is configured to control on/off of the MOSFET through the control circuit, to implement connection/disconnection between the storage battery and the contactor.

Abstract: An integrated controller includes: a box; a controller and a charging/discharging converter disposed in the box; and a high-voltage interface assembly including a high-voltage interface disposed on the box and a high-voltage connector disposed in the box. The high-voltage connector is connected with the high-voltage interface, the controller, and the charging/discharging converter to receive and distribute a high-voltage battery signal.

Abstract: The present disclosure relates to the technical field of vehicles, and provides an electric vehicle and an integrated controller and an integrated control system therefor. The integrated controller includes: a first control chip, including a first core and a second core, where the first core is configured to control an electronic control module to drive a motor, and the second core is used as a vehicle controller; and a second control chip, configured to control an on-board charging module, so that an external AC power supply realizes AC charging for a power battery, or the power battery realizes AC discharging to an external load through an AC charging and discharging port.

Abstract: A motor control system of an electric vehicle, a controlling method for the motor control system and an electric vehicle are provided. The motor control system includes: an IGBT module, connected with a motor of the electric vehicle; a detection module, configured to detect a motor speed; a drive module, configured to drive IGBTs in the IGBT module to turn on or off so as to control the motor to work or stop working; a first control module; a second control module communicated with the first control module; and a channel selection module, configured to select a channel of the second control module when the first control module has a fault. When the second control module is selected, it sends a second control signal to the drive module according to the motor speed at a predetermined time before the first control module has the fault, so as to control the motor to stop working.
