Title:
CIRCUIT FOR CONTROLLING CELL, AND ELECTRONIC DEVICE
Document Type and Number:
WIPO Patent Application WO/2022/036667
Kind Code:
A1
Abstract:
A circuit (100) for controlling a cell, and an electronic device (200). The circuit (100) comprises a first charging path (110), which is used for matching a customized adapter for charging, and comprises a first SC converter (1221) that can support voltage conversion in a fixed ratio; and a second charging path (120), which is used for matching a non-customized adapter for charging, and comprises a first switching conversion circuit (1220) and a second SC converter (1223), wherein the first switching conversion circuit (1220) supports a buck mode, and the second charging path (120) can realize voltage conversion in a variable ratio, thereby supporting a charging mode that requires current stabilization. The circuit (100) may be compatible with customized adapters and non-customized adapters, thereby improving the flexibility and management efficiency of controlling the charging and discharging of the cell.
