A current collector for the load has at least one sliding contact for contacting the profiled conductor section of the conductor strand of the conductor line and at least one antenna for transmitting data to a conductor line signal transmission device, which moves in the longitudinal direction. A conductor line system includes such a conductor line and current collector. An aim is to allow a compact and material-saving design as well as a good fault-tolerant transmission. This is achieved by a conductor line in which the signal transmission device and the profiled conductor section are designed as one component, by a current collector in which the sliding contact and the antenna are designed as one component, and by a conductor line system including such a conductor line and such a current collector.

Example embodiments of systems, devices, and methods are provided for electric vehicles that are subject to intermittent charging, such as rail-based electric vehicles, having one or more modular cascaded energy systems. The one or more modular systems can be configured to supply multiphase, single phase, and/or DC power to numerous motor and auxiliary loads of the EV. If multiple systems or subsystems are present in the EV, they can be interconnected to exchange energy between them in numerous different ways, such as through lines designated for carrying power from the intermittently connected charge source or through the presence of modules interconnected between arrays of the subsystems. The subsystems can be configured as subsystems that supply power for motor loads alone, motor loads in combination with auxiliary loads, and auxiliary loads alone.
