Abstract:
Disclosed are an active discharge system for an electric vehicle and an electric vehicle comprising the system. The system comprises a power battery (10), a bus capacitor (CO), a charge-discharge socket (20), a two-way DC/DC module (30), a drive control switch (40), a two-way DC/AC module (50), a motor control switch (60), a charge-discharge control module (70), and a controller module (80). The controller module (80) is connected to the drive control switch (40), the motor control switch (60) and the charge-discharge control module (70), and the control module (80) is used for controlling the drive control switch (40), the motor control switch (60) and the charge-discharge control module (70) in accordance with the current operating mode of the active discharge system. The active discharge system can achieve high-power alternating-current (AC) charging to the electric vehicle using a civil or industrial AC power grid so that users can perform a quick charge at high efficiency, anytime and anywhere. In addition, suitable batteries have a wide range of operating voltages, thereby saving space and costs.
