A charge control system for an electric vehicle and an electric vehicle are provided. The charge control system includes: a charge-discharge socket (20); a three-level bidirectional DC-AC module (30); a charge-discharge control module (50); a filtering module (70); and a control module (60) connected with a third terminal of the charge-discharge control module (50) and configured to control the charge-discharge control module (50) to turn on, to sample an output voltage of an external grid by using a connection midpoint of filtering capacitors in the filtering module (70) as a reference point, and to control the three-level bidirectional DC-AC module (30) according to the output voltage of the external grid so as to control the external grid to charge the power battery (10), when the external grid is in an angle connection mode and the electric vehicle is a charge-discharge mode.
