Title:
CIRCUIT SYSTEM AND FOLDABLE TERMINAL
Document Type and Number:
WIPO Patent Application WO/2024/045698
Kind Code:
A1
Abstract:
A circuit system and a foldable terminal, relating to the technical field of terminals, and being used for reducing the impedance of a jumper wire of a power supply path between two circuits applied to different panels and related to system charging and discharging in the foldable terminal, thereby reducing the path power consumption during charging and discharging. The foldable terminal comprises a first panel and a second panel, and the circuit system comprises a first circuit applied to the first panel and a second circuit applied to the second panel, the two circuits being coupled by means of a power supply path wire in a hinge connecting the two panels; the first circuit comprises a fast charging circuit, a non-fast charging circuit, a first control switch, a first power switch and a second power switch, and the second circuit comprises a second control switch; by controlling the turning-on and turning-off of the four switches, the fast charging circuit can perform series charging on a first battery corresponding to the first panel and a second battery corresponding to the second panel, and the non-fast charging circuit can perform parallel charging on the first battery corresponding to the first panel and the second battery corresponding to the second panel.
