Title:
BIDIRECTIONAL CHARGING CIRCUIT AND APPARATUS
Document Type and Number:
WIPO Patent Application WO/2023/015720
Kind Code:
A1
Abstract:
The present disclosure relates to a bidirectional charging circuit and apparatus. The bidirectional charging circuit comprises a first transmission module, a main control module, a power source module, and a logic control module, wherein the logic control module is used for outputting a first detection signal to the main control module when it is detected that the first transmission module is connected to an external electronic device; the first transmission module is used for being connected to the external electronic device or a power adapter, and outputting a second detection signal to the main control module when it is detected that the first transmission module is connected to the power adapter; the main control module is used for outputting a first control signal to the power source module according to the first detection signal, or outputting a second control signal to the power source module according to the second detection signal; and the power source module is used for supplying electric energy to the external electronic device via the first transmission module according to the first control signal, or for receiving, according to the second control signal, electric energy input by the power adapter via the first transmission module so as to supply electric energy to the main control module. In the present disclosure, a first transmission module is added to perform bidirectional charging on a power source module, thereby reducing resource waste.
