Title:
BIDIRECTIONAL ENERGY TRANSMISSION APPARATUS, ON-BOARD CHARGER, AND ELECTRIC VEHICLE
Document Type and Number:
WIPO Patent Application WO/2021/196309
Kind Code:
A1
Abstract:
A bidirectional energy transmission apparatus (30), comprising: a controller (303) and a bidirectional energy conversion and transmission circuit (300), wherein a control end (303a) of the controller (303) is connected to a controlled end (300c) of the bidirectional energy conversion and transmission circuit (300); and the controller (303) is used for controlling the bidirectional energy conversion and transmission circuit (300) to be in a rectification working state, so as to convert a three-phase or single-phase alternating-current voltage input from a first port (300a) of the bidirectional energy conversion and transmission circuit (300) into a first direct-current voltage, and to output the first direct-current voltage from a second port (300b) of the bidirectional energy conversion and transmission circuit (300), or, for controlling the bidirectional energy conversion and transmission circuit (300) to be in an inversion working state, so as to convert the first direct-current voltage input from the second port (300b) of the bidirectional energy conversion and transmission circuit (300) into a three-phase or single-phase alternating-current voltage, and to output the three-phase or single-phase alternating-current voltage from the first port (300a) of the bidirectional energy conversion and transmission circuit. The controller (303) controls the bidirectional energy conversion and transmission circuit (300) to be in different working states, such that bidirectional conversion between a three-phase/single-phase alternating-current voltage and a direct-current voltage is realized; and configurations are flexible.
