Embodiments of this application disclose an in-vehicle charge and discharge system and control method. The system includes: an alternating current interface, an isolating transfer switch, a first converter, a second converter, a high-voltage battery interface, a low-voltage battery interface, and a controller. The controller is configured to: control the isolating transfer switch to switch to a first conducting state, so that the alternating current interface is conducted with the high-voltage battery interface by using the first converter and the second converter that are connected in series; and control the first converter to work in a PFC mode or an inverting mode, and control the second converter to work in a DCDC isolating conversion mode. The controller is further configured to: control the isolating transfer switch to switch to a second conducting state, so that the low-voltage battery interface is conducted with the high-voltage battery interface by using the first converter and the second converter that are connected in series; and control the first converter to work in a DCDC conversion mode, and control the second converter to work in the DCDC isolating conversion mode. This structure can reduce a size of the in-vehicle charge and discharge system.
