Communication system, management device, and non-transitory computer readable storage medium

A management device includes:

• an electronic fuse control unit that is configured to control an operation of an electronic fuse for switching between a conduction state in which a power supply path is conducted for supplying electric power from a power source to a first control device and a cutoff state in which the power supply path is cut off;
• a communication unit that is configured to perform data communication with a second control device connected to the first control device so as to be able to perform data communication with the first control device;
• and
• a power source cutoff notification unit that is configured to perform at least one of:
• a pre-cutoff notification process of transmitting power source pre-cutoff notification information to the second control device notifying that electric power supply from the power source via the electronic fuse will be cut off before turning off the electronic fuse to cut off the electric power supply from the power source to the first control device;
• and a post-cutoff notification process of transmitting power source post-cutoff notification information to the second control device notifying that the electric power supply from the power source via the electronic fuse has been cut off after the electronic fuse has been turned off to cut off the electric power supply from the power source to the first control device.

A non-transitory computer readable storage medium comprising instructions being executed by a computer, the instructions causing the computer to function as:

• an electronic fuse control unit that is configured to control an operation of an electronic fuse for switching between a conduction state in which a power supply path is conducted for supplying electric power from a power source to a first control device and a cutoff state in which the power supply path is cut off;
• a communication unit that is configured to perform data communication with a second control device connected to the first control device so as to be able to perform data communication with the first control device;
• and
• a power source cutoff notification unit that is configured to perform at least one of:
• a pre-cutoff notification process of transmitting power source pre-cutoff notification information to the second control device notifying that electric power supply from the power source via the electronic fuse will be cut off before turning off the electronic fuse to cut off the electric power supply from the power source to the first control device;
• and a post-cutoff notification process of transmitting power source post-cutoff notification information to the second control device notifying that the electric power supply from the power source via the electronic fuse has been cut off after the electronic fuse has been turned off to cut off the electric power supply from the power source to the first control device.
