  "textContent": "This application relates to the field of charging management, and provides a method for detecting impedance of a charging cable, an electronic device, and a power supply device, to more accurately detect impedance of a charging cable. The method includes: receiving, by the electronic device, first electric energy from the power supply device through the charging cable, and obtaining a first source voltage detection value of the first end of the charging cable and a first final voltage detection value of the second end of the charging cable, where a voltage of the first electric energy is constant, and a current of the first electric energy is a first current value; receiving, by the electronic device, second electric energy from the power supply device through the charging cable, and obtaining a second source voltage detection value of the first end of the charging cable and a second final voltage detection value of the second end of the charging cable, where a voltage of the second electric energy is the same as the voltage of the first electric energy, and a current of the second electric energy is a second current value; and calculating, by the electronic device, an impedance value of the charging cable according to the first source voltage detection value, the second source voltage detection value, the first final voltage detection value, the second final voltage detection value, the first current value, and the second current value.",
