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.
Abstract:
An apparatus (1) for charging an electric vehicle(3), a communication apparatus (2) and an electric vehicle (3) are provided. The apparatus (1) includes: dual charging guns (10), each having a communication wire; a first carrier module (12), connected with a first terminal of each communication wire(101,102); a first control module (13), connected with the first carrier module (12) and the first terminal of the each communication wire(101,102), and configured to control the first carrier module (12) to output an obtaining information signal when obtaining charging connection signals of the dual charging guns (10), in which the first carrier module (12) is configured to obtain a carrier signal, to decode the carrier signal to obtain a decoded carrier signal, and to send the decoded carrier signal to the first control module (13); and a power source(GND) configured to provide power to the first carrier module (12) and the first control module (13).
