Abstract: A high-voltage charging arrangement (2) is provided for charging a traction battery (20) of an electric vehicle at a DC charging station (4). The DC charging station (4) has a first voltage (Vin) and the traction battery (20) has a second voltage (Vout). At least one DC-DC converter (10) has a first conduction path (12) with a converter (16) for transforming the first voltage (Vin) into the second voltage (Vout) and a second conduction path (14) has a bypass (18) for bypassing the converter (16). A control device (26) communicates with the DC charging station (4) is possible. An input element (28) is provided for selecting a conduction path (12, 14) and is connected to the control device (26) for control purposes. A method also is provided for performing a charging process for a traction battery (20) of an electric vehicle at a DC charging station (4).

Abstract: A method of generating flow data indicative of speeds of travel within a navigable network in an area covered by an electronic map is disclosed. The electronic map comprises a plurality of segments representing navigable elements of the navigable network. Live vehicle probe data is obtained indicative of the average speed of travel for the current time with respect to distance along a link, the link being predetermined by reference to the electronic map. The link is sectioned to provide a plurality of sections along the length thereof. The sectioning is carried out based on the data indicative of the current average speed of time along the link. Where a differential in the current average speed exceeds a threshold, a new section is created.

Abstract: A method and system for identifying a lateral deviation in the course of a road segment is described. Positional data is collected from a plurality of vehicles travelling along a road stretch. A map matching error associated with the position data is used to determine an average map matching error and average absolute map matching error for travel along the road stretch. A lateral deviation in course is identified when the average map matching error measures are both above a given threshold, and where the detected deviation is of a given minimum length. Other indicators of deviation can be considered including a direction of the possible deviation, and impact on travel in the opposite driving direction. Data relating to the determined deviation is generated, including a speed of travel through the deviated region, and used to enhance traffic information.

Abstract: A method of verifying and/or improving a message indicative of an event affecting traffic flow on at least a portion of one or more navigable segments is described. The method involves obtaining positional data relating to the movement of a plurality of devices along a navigable stretch including a navigable stretch identified by the message as being affected, and using the positional data to verify and/or improve the message. The positional data is live data and is used to obtain data relating to the speed of travel of the devices along the navigable stretch including the stretch identified by the message. The speed data can be used to determine a spatial extent of the affected stretch and/or an expected speed of travel along the stretch.
