CHARGING CONTROL SYSTEM, CHARGING STATION, AUTONOMOUS TRAVELING WORK MACHINE, AND CHARGING CONTROL SYSTEM CONTROL METHOD

A charging control system 100 includes a lawn mower 2 that includes a battery 17 and performs a lawn mowing work while traveling autonomously, and a charging station 3 for charging the battery 17. The lawn mower 2 includes a superimposing unit 203 for superimposing, on a charging current JB, a current indicating period information DP for defining a shutoff period PC of supply power PS to be supplied from the charging station 3. The charging station 3 includes a current detector 311A for detecting the charging current JB, an information acquisition unit 311B for acquiring period information DP based on a detection result of the current detector 311A, a switch 312 for shutting off the supply power PS, and a shutoff controller 311C for controlling the operation of the switch 312. The shutoff controller 311C releases the shutoff of supply of power to the lawn mower 2 based on the period information DP acquired by the information acquisition unit 311B. Therefore, the power consumption of the lawn mower 2 can be reduced.
