An electric locomotive includes a first control line and DC buses laid between couplers, a power storage device connected to the DC buses, and a DC/DC converter that executes charge and discharge control with respect to the power storage device. A non-powered vehicle includes DC buses connected to the DC buses via a coupler, a second control line, a power storage device connected to the DC buses via a circuit breaker, and a BMU that manages the power storage device. The DC/DC converter executes power accumulation control with respect to the power storage device and power accumulation control with respect to the power storage device. When having determined abnormality of the power storage device, the BMU controls the circuit breaker to be turned off, thereby cutting off electrical connection between the power storage device and the DC buses.

In a method of operating a motor vehicle driven electrically, at least temporarily, on a roadway, the motor vehicle is moved fully autonomously by a control unit in response to a command for automatic operating mode. After a charging arm of the motor vehicle has been extended, a lateral control of the motor vehicle is executed to bring the extended charging arm into electric contact with a charging line arranged at or on the roadway. As a result, electric energy provided from the charging line to the charging arm is used for charging an energy accumulator of the motor vehicle and/or operating a drive device of the motor vehicle for moving the motor vehicle. A longitudinal control of the motor vehicle is executed to thereby maintain a predefined longitudinal speed of the motor vehicle until a distance of the motor vehicle reaches a predefined minimum distance to a leading vehicle.

A moving body includes: a first body including at least one wheel, an electric motor and a first secondary battery; and a second body attachable to and detachable from the first body and including an electric power load and a second secondary battery. When the second body is mounted on the first body, at least one of the second secondary battery and the first secondary battery is allowed to be charged in a charging mode including at least one of a first charging mode and a second charging mode. In the first charging mode, the second secondary battery is charged using electric power output from the first secondary battery. In the second charging mode, the first secondary battery is charged using electric power output from the second secondary battery.
