Title:
VEHICLE-MOUNTED CHARGING/DISCHARGING APPARATUS AND SYSTEM
Document Type and Number:
WIPO Patent Application WO/2020/258939
Kind Code:
A1
Abstract:
A vehicle-mounted charging/discharging apparatus (200) and a system. The vehicle-mounted charging/discharging apparatus (200) comprises: 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 used to convert a received first alternating-current voltage into a first direct-current voltage or convert a second direct-current voltage outputted by the bidirectional DC/DC conversion circuit (203) into a second alternating-current voltage. The unidirectional DC/DC conversion circuit (202) is used 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 used 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 a second direct-current voltage. The first component and the second component form the first direct-current voltage. The vehicle-mounted charging/discharging apparatus (200) and the system achieve charging and discharging.
