An on-board charging and discharging apparatus (200) and a system are provided. The apparatus includes: a bidirectional AC/DC conversion circuit (201), a unidirectional DC/DC conversion circuit (202), and a bidirectional DC/DC conversion circuit (203). The bidirectional AC/DC conversion circuit (201) is configured to convert a received first alternating current voltage into a first direct current voltage, or convert a second direct current voltage output by the bidirectional DC/DC conversion circuit (203) into a second alternating current voltage. The unidirectional DC/DC conversion circuit (202) is configured to convert a first component of the first direct current voltage into a third direct current voltage. The bidirectional DC/DC conversion circuit (203) is configured to convert a second component of the first direct current voltage into a fourth direct current voltage, or convert a received fifth direct current voltage into the second direct current voltage. The first component and the second component constitute the first direct current voltage. The on-board charging and discharging apparatus (200) and the system are configured to implement charging and discharging functions.
