1. An electronic device comprising:
a CPU; and
a memory storing a program which, when executed by the CPU, causes the electronic device to perform:
a first detection of detecting that a cable is connected to the electronic device;
a second detection of detecting a temperature of the cable connected to the electronic device;
a communication of receiving cable information including information related to the cable from the cable connected to the electronic device;
a first setting to set a threshold temperature to a second threshold temperature being preset and representing an upper limit value of a permissible temperature of a typical cable to be connected to the electronic device, in a case where the first detection has detected that the cable is connected to the electronic device;
a second setting to set the threshold temperature to a third threshold temperature representing a temperature value indicated by the cable information, in a case where the communication has received the cable information from the cable and the third threshold temperature is higher than the second threshold temperature; and
controlling a power supply device to stop supplying power from the power supply device to the electronic device via the cable or controlling the electronic device to stop receiving power from the power supply device via the cable, in a case where a temperature of the cable detected by the second detection is higher than the set threshold temperature.
