WORK MACHINE CONTROL METHOD, WORK MACHINE CONTROL PROGRAM, WORK MACHINE CONTROL SYSTEM, AND WORK MACHINE

A hydraulic excavator as a work machine includes a battery that stores electric power, a connector to which a charging cable used to charge the battery is connected, and an electric motor that is driven by electric power supplied from the battery. A method of controlling the hydraulic excavator includes detecting a connection state between the charging cable and the connector, and performing a suppression process of suppressing an action of the hydraulic excavator while permitting the action of the hydraulic excavator based on the connection state in a case where the electric motor is in a rotatable state.
