Document Type and Number:
WIPO Patent Application WO/2022/121588
Kind Code:
A1
Abstract:
Disclosed in the present application are a charging and discharging apparatus and a power transmission method thereof, relating to the field of battery power. The charging and discharging apparatus comprises: a communication module, the communication module being communicatively connected to a BMS and being used for performing first communication with the BMS on the basis of a universal charging protocol when in a first energy transmission mode and in the case that the BMS does not support a specific discharging protocol; and a conversion module, one side of the conversion module being connected to a battery and the other side of the conversion module being connected to an alternating current-side connecting structure, and being used during the first communication for converting direct current provided by the battery into alternating current and transmitting the alternating current to the alternating current-side connecting structure, the first energy transmission mode being a mode in which the battery transmits power to the alternating current-side connecting structure of the apparatus. By means of the embodiments of the present application, discharge of the battery can be implemented in the case that the BMS does not support a specific discharging protocol.
