  • Electric vehicle and active discharging system for electric vehicle
    Patent number: 9290105
    Abstract: An active discharging system for an electric vehicle and an electric vehicle including the same are provided. The active discharging system includes a power battery; a bus capacitor; a charge-discharge socket; a bidirectional DC/DC module; a driving control switch; a bidirectional DC/AC module; a motor control switch connected with the bidirectional DC/AC module and a motor; a charge-discharge control module connected with the bidirectional DC/AC module and the charge-discharge socket; and a controller module configured to control the driving control switch, the motor control switch and the charge-discharge control module according to a current operation mode of the active discharging system, to control the bus capacitor to continue charging the power battery after a charge is finished, and to control the bus capacitor to continue discharging after a discharge is finished until a voltage across the bus capacitor is less than a first predetermined value.
