A system and method of charging an electric vehicle uses a modular ground transceiver station (GTS) having at least two ground transceiver assemblies (GTAs). Each GTA is adapted to align with a vehicle transceiver assembly (VTA) of the electric vehicle, and a guideline extends from at least one of the GTAs a predetermined distance for guiding the electric vehicle to the GTAs. The GTS is selected based on an active GTA configuration of the GTS and a VTA configuration of the electric vehicle. The electric vehicle is guided along the guideline for alignment of at least one VTA of the electric vehicle with at least one of the GTAs in response to at least one signal radiated by the guideline. Wireless charging is initiated upon verification of alignment of the at least one VTA of the electric vehicle and the at least one of the GTAs.

A contactless charger system for charging a power storage unit of an electrically driven vehicle, such as an e-bike. The contactless charger system has a power transmission part with a primary coil around a primary magnetic circuit part including two primary pole faces, and a power receiving part with a secondary coil around a secondary magnetic circuit part having two secondary pole faces (8). In operation, the two primary pole faces and the two secondary pole faces are aligned such that the primary and secondary magnetic circuit parts form a closed magnetic circuit. The secondary magnetic circuit part is an integral part of an electrically driven vehicle stand.

A server manages plural vehicles each configured to be able to participate in a DR. A first vehicle is able to transmit power through a power cable. A second vehicle is able to transmit power in a non-contact manner while being stationary. A third vehicle is able to transmit power in a non-contact manner while traveling. The server includes a communication device and a processing device. The communication device is able to transmit a DR signal to each of the vehicles. The processing device selects a target vehicle, to which the DR signal is to be transmitted, from the vehicles in accordance with the priority degree for participation in the DR. The processing device sets the priority degree of the first vehicle to be higher than that of the second vehicle, and sets the priority degree of the second vehicle to be higher than that of the third vehicle.

The invention relates to a coil apparatus for an inductive receiving apparatus, including a first coil with a plurality of first turns and a second coil with a plurality of second turns, wherein the first and the second coils are connected to one another in series and are wound in opposite directions relative to each other, wherein each turn includes an internally arranged conductor section and an externally arranged conductor section. With the objective of improving the interoperability of the coil apparatus, a portion of the first and second turns include respectively the internally and externally conductor section arranged such that the first and second turns respectively lie in one plane or span one plane, wherein these planes diverge with respect to one another in the direction from the first coil to the second coil or vice versa, depending on whether the conductor sections are in the portion of the first turns or of the second turns.

A wireless charging power supply system during operation of electric vehicles and industrial equipment while operating is described. The withstand voltage problem on the power supply line was solved by the capacitor provided in the inverter, and the power supply line and common line arrangement. This makes it possible to extend the wireless power supply line and the economical problem of the wireless charging system is greatly improved. In the prior art, compatibility was maintained with various wireless charging pick-up pads installed in the vehicle by using a plurality of inverters. In this system, compatibility is satisfied at a lower cost by utilizing the relay present in the inverter. The EMI of the power supply line is reduced by maximizing the magnetic field cancellation effect by using the structure of the common line and the shielding tube.

An on-travel power supply system is provided to include (i) a power supply facility including a plurality of power supply apparatuses arranged along a traveling road, and (ii) an electric vehicle including a power reception apparatus configured to receive power supply from the power supply apparatuses and charge a battery while traveling on the traveling road. The electric vehicle is configured to acquire, from the power supply facility, a failed road segment in which power supply is disabled from the power supply apparatuses along the traveling road. The electric vehicle is further configured to calculate a required energy amount required for the electric vehicle to pass through the failed road segment, and secure the calculated required energy amount before the electric vehicle reaches the failed road segment.
