Abstract:
The present application relates to the detection of moving vehicles and other objects, in particular though not exclusively for the application of switching stationary charging pads for moving electric vehicle charging. There is provided an electric vehicle detecting apparatus for switching a charging pad for charging a vehicle transmitting a locating signal, the apparatus comprising two sensors separated in the direction of travel of the vehicle, and a detector arranged to detect the vehicle by comparing the locating signals received by each of the two sensors.
Abstract:
An apparatus comprising a charging unit and comprising a vehicle for inductive charging, in which the charging unit comprises a primary coil, and the vehicle comprises a secondary coil in order to transmit electrical power from the primary coil to the secondary coil during a charging operation, wherein the vehicle comprises a camera system, the vehicle comprises a camera control device, the camera system captures at least one image of the charging unit on increasing proximity to the charging unit, at the beginning of a charging operation and/or during a charging operation, and the camera control device digitally processes the at least one captured image in order to identify a foreign body located on the charging unit.
Abstract:
Apparatus, having a charging unit and having a vehicle, for inductively transmitting power from the charging unit to the vehicle, in which apparatus the charging unit comprises a primary coil and the vehicle comprises a secondary coil, and in which apparatus the primary coil generates a magnetic transmission field in a transmission region between the primary coil and the secondary coil, wherein the vehicle has a sensor unit for monitoring the temperature in the transmission region, the charging unit comprises a control apparatus, and the transmission power can be controlled (3) by the control apparatus during a charging process depending on a result of the temperature monitoring process.
Abstract:
This disclosure provides systems, methods and apparatus for wireless power transfer. In one aspect an apparatus for wirelessly transferring power from a charging power source to a device is provided. The apparatus includes a first strand wound in one or more turns and operationally coupled to the charging power source and a second strand wound together with the first strand in one or more turns and operationally coupled to the charging power source. The apparatus further includes an inductor circuit connected to the first strand and disconnected from the second strand. The inductor circuit is further configured to reduce a current difference between a first current flowing through the first strand and a second current flowing through the second strand.
Abstract:
Die Erfindung betrifft ein Verfahren (42) zum Betreiben einer drahtlosen Energieübertragungsanordnung (10) mit einem Primärglied (18) und einem Sekundärglied (20), die induktiv koppelbar sind, um elektrische Energie von dem Primärglied (18) auf das Sekundärglied (20) zu übertragen, wobei eine einstellbare Lastimpedanz an das Sekundärglied (20) gekoppelt ist, wobei elektrische Ersatzgrößen für ein elektrisches Modell (34) der Energieübertragungsanordnung (10) ermittelt werden, wobei das elektrische Modell (34) ein elektrisch leitfähiges Objekt (32) in einer Übertragungsstrecke (28) zwischen dem Primärglied (18) und dem Sekundärglied (20) berücksichtigt, wobei ein Impedanzwert der Lastimpedanz auf der Grundlage der elektrischen Ersatzgrößen und einer ermittelten elektrischen Verlustleistung des in der Übertragungsstrecke (28) angeordneten Objekts (32) bestimmt wird, und wobei die Lastimpedanz auf den Impedanzwert eingestellt wird.
