This disclosure provides systems and methods for charging a vehicle. A vehicle and charging station can be designed such that an electric or hybrid vehicle can operate in a fashion similar to a conventional vehicle by being opportunity charged throughout a known route.

Disclosed is a method of and control system for operating a circuit arrangement, in particular a circuit arrangement of an electric vehicle for inductive power transfer to the vehicle. The circuit arrangement includes at least one phase line with at least one field receiving arrangement and at least one compensating arrangement with a variable reactance, wherein at least one current-dependent cost function is evaluated, wherein the reactance is varied such that the cost function is optimized.

This invention relates to a vehicle power coupling apparatus for a vehicle. The apparatus has a pickup coil arrangement for receiving an alternating magnetic field applied to the vehicle for generating power to operate the vehicle. The apparatus further has a shield for shielding a region including the pickup coil arrangement from an interior of the vehicle where a user of the vehicle may be present when the vehicle is in operation, and the shield includes at least one hole therein for providing access to one or more components of the vehicle for working on the one or more components. Additional aspects of the invention relate to receiving an alternating magnetic field and converting the alternating magnetic field into electrical power for recharging a vehicle and/or for providing motive power to the vehicle.

A power line system is provided for efficiently using excess electrical energy produced by electric vehicles in a generation mode. A power line detector on the vehicle senses the power line to determine if voltage ripples are present before supplying excess electrical energy from the vehicle to the power line. First voltage ripples are generated on the line by a substation providing power to the power line. Second voltage ripples are also generated on the power line by a ripple generator to allow excess energy from the vehicle to be supplied to the power line in order to charge an energy storage system.

An apparatus comprises a first induction section comprising a first core and a first coil on the first core. A second induction section comprises a second core and a second coil on the second core. The first core comprises rail extensions, where at least two of the rail extensions extend from opposite ends of the first core. The second core comprises shoe portions located at respective ones of the rail extensions, where a gap is provided between each of the rail extensions and respective ones of the shoe portion. The second induction section is configured to move relative to the first induction section in a path along the extensions. The first induction section is configured to induce current in the second induction section, including when the second core moves relative to the first core along the extensions, to provide a contactless induction coupling between the first induction section and the second induction section.
