ELECTRIC AUTOMOBILE SYSTEM INTEGRATING CHARGING AND DRIVING FUNCTIONS, AND CONTROL METHOD THEREFOR

An electric automobile system integrating charging and driving functions. The system is mainly characterized by comprising a high-voltage interlocking device. The high-voltage interlocking device comprises a charging cover (2), a locking latch device and a detection switch (6). External three-phase alternating current is input through an input connector. The input connector is covered by the charging cover so that a high-voltage terminal on the input connector is not exposed. The locking latch device is used for locking the charging cover (2) when the charging cover (2) is closed. The detection switch (6) is used for detecting the opening or closing state of the charging cover and transmitting a signal to a driving/charging switching controller. Also provided is a control method for the system. The control method is mainly characterized in that: two conditions must be satisfied before entering the charging procedure, namely, 1) the charging cover (2) is opened first, and the detection switch used for detectin
