The application provides a bi-directional DC/DC converter, a control method and apparatus thereof, and a storage medium. The control method includes: obtaining a first voltage value output by a first rectifier module in a current control cycle; obtaining a second voltage value output by a second rectifier module in the current control cycle; calculating a theoretical voltage control quantity of the bi-directional DC/DC converter in the current control cycle based on a preset reference voltage value and the second voltage value; and setting an actual output voltage of the bi-directional DC/DC converter in a next control cycle based on the theoretical voltage control quantity and the first voltage value. In this way, a voltage tracking error in the next control cycle may be reduced. Moreover, because PI parameters are not required for control, an output theoretical voltage control quantity is no longer a frequency but a switching signal, which may avoid frequency hopping during switching.
