The invention provides a charging system used for an electric automobile. The charging system comprises a power battery, a charging and discharging socket, a bidirectional DC/DC (direct current to direct current) module, a drive control switch, a bidirectional DC/AC (direct current to alternating current) module, a motor control switch, a charging and discharging control module and a controller module, wherein the controller module is connected with the drive control switch, the motor control switch and the charging and discharging control module; and the controller module is used for controlling the drive control switch, the motor control switch and the charging and discharging control module according to the current working mode of the charging system. The charging system can be used for carrying out high-power alternating current charging on an electric automobile by using a civil or industrial alternating current power grid, so that a user can charge efficiently and quickly anytime and anywhere, the working voltage range for the battery is wide, and space and cost can be saved. The invention also provides the electric automobile.
