According to some embodiments, a rail transport vehicle electric energy storage and charging system is presented. The system may include an energy storage sub-system and a charging system having a charging rail which only charges a vehicle when the rail is covered. The system may also include a battery-powered rail vehicle having a rail-contacting charging shoe.

A train includes: a body, a pantagraph current collector and an ice scraper, wherein the pantagraph current collector is provided on the body; and the ice scraper is mounted on the pantagraph current collector, and the ice scraper is in contact with a power supply rail, so as to remove ice on the power supply rail during the movement of the body. Thus, it is ensured that the pantagraph current collector can be in effective contact with the power supply rail during the running of the train, and normal power supply of the train is ensured. The problem in the conventional art in which the current receiving performance of a current receiver of a train is greatly reduced when a power supply rail is frozen or suffers from heavy snow is solved.

A system includes a phase break input unit, one or more vehicle location detectors, and one or more processors. The phase break input unit is configured to obtain phase break location information indicating a location of a phase break along a route to be traversed by a vehicle. The one or more vehicle location detectors are configured to obtain vehicle location information indicating at least one of location of the vehicle or movement of the vehicle. The one or more processors are configured to determine an estimated arrival time of the vehicle at the phase break using the phase brake location information and the vehicle location information, and send a phase break control signal to a control system of the vehicle responsive to the estimated arrival time satisfying a threshold.

A charging device for a vehicle including an electric storage arrangement. The charging device is arranged to be mounted to a portion of the vehicle, the charging device including a movable contacting element for electric contact with a stationary contacting element for electric charging of the electric storage arrangement. The charging device further includes an actuator for moving the movable contacting element between a retracted position and a protruded position, the charging device being arranged so that, while the vehicle is in a charging position in relation to the stationary contacting element, the stationary contacting element can be reached by the charging device, while the movable contacting element is in the protruded position, for the electric contact between the movable contacting element and the stationary contacting element, wherein a protective element arranged to restrict access to the movable contacting element and the stationary contacting element when the movable contacting element and the stationary contacting element are in the electric contact with each other.

In a local cart traveling system, a frame track includes first and second metal rails each with an L-shaped cross section and facing each other. A local cart is within the frame track, and includes a first electricity receiving tire and a second electricity receiving tire to travel on horizontal travel surfaces of the rails. A voltage supplier supplies an AC voltage to the travel surfaces, so that the first metal rail and a first electricity receiving tire define a first capacitor and the second metal rail and the second electricity receiving tire define a second capacitor. The local cart includes a power receiver to receive AC power, and a travel motor that receives power after the AC power is rectified. The frame track includes a connecting plate as an electrical insulator covering portions of the surfaces of vertical walls of the first metal rail and the second metal rail.

The invention relates to a method and an arrangement for inductive positioning of a current collector (14; 24) on a vehicle relative to a stationary current conductor (13; 23; 33; 43; 53). The invention involves transmitting a signal having predetermined phase characteristics using a signal transmitter (37; 47; 57) arranged along the longitudinal direction of the current conductor (13; 23; 33; 43; 53); detecting the transmitted signal using a signal receiver on the vehicle, which signal receiver comprises at least one vertical antenna (30; 40; 50a, 50b); detecting the phase characteristics of the signal induced in the at least one vertical antenna (30; 40; 50a, 50b), indicating the relative location of the vertical antenna (30; 40; 50a, 50b) and the signal transmitter (37; 47; 57) in the transverse direction of the vehicle; and controlling the positioning means (25, 26) in dependence of the received signals.
