Embodiments of this application provide an electric vehicle battery voltage regulation system and a control method and control apparatus therefor. The control method includes: controlling a first switch, a second switch, a third switch, a fourth switch, a fifth switch, a first leg, and a second leg set to turn on or off, to form in a first period a circuit loop for a charge/discharge module to discharge to a motor and to form in a second period a circuit loop for the charge/discharge module and the motor to charge a first electric vehicle battery group and a second electric vehicle battery group or form in the second period a circuit loop for the motor to charge the first electric vehicle battery group and the second electric vehicle battery group; or controlling the first switch, the second switch, the third switch, the fourth switch, the fifth switch, the first leg, and the second leg set to turn on or off, to form in a third period a circuit loop for the first electric vehicle battery group and the second electric vehicle battery group to discharge to the motor and to form in a fourth period a circuit loop for the first electric vehicle battery group, the second electric vehicle battery group, and the motor to discharge to the charge/discharge module or form in the fourth period a circuit loop for the motor to discharge to the charge/discharge module.
