Description

technical field

[0001] The present disclosure relates to the technical field of charging, and in particular to an electronic device, a charging method thereof, and a readable storage medium. Background technique

[0002] At present, in the process of charging a battery in an electronic device, it is necessary to detect the real-time voltage and current of the battery, and further adjust the charging strategy based on the real-time voltage and / or current. Taking voltage detection as an example, the detection point of the battery voltage is usually the battery connector on the electronic device. The voltage detection circuit needs to be connected to the battery through the battery connector, the flexible circuit board (FPC) of the battery, and the battery protection board. Due to the flexibility of the battery The circuit board (FPC), battery protection board, and even the battery have certain impedances, which cause the voltage detected by the voltage detection circuit on the...
