Abstract: A communication system includes: a first control device receiving electric power supply from a power source via an electronic fuse; a second control device connected to the first control device for data communication; and a management device connected to the first and second control devices for data communication and controlling the electronic fuse. The management device performs at least one of: transmitting power source pre-cutoff notification information to the second control device notifying that the electric power supply will be cut off before turning off the electronic fuse; and transmitting power source post-cutoff notification information notifying that the electric power supply has been cut off after turning off the electronic fuse.
