Embodiment Construction

[0043] exist figure 1 In , a vehicle 1 is located at a charging station 2 using a wireless power transfer system 3 . The wireless power transmission system 3 includes a transmitter 4 arranged on a floor 5 and a receiver 6 arranged in the vehicle 1 . Such transmitters may be arranged on or in the floor or ground. Furthermore, the receiver 6 is preferably arranged on the underside of the vehicle 1 . The transmitter 4 has a primary coil for generating an electromagnetic field, and the receiver 6 has a secondary coil for interacting with the generated electromagnetic field to enable power transmission from the primary coil to the secondary coil by electromagnetic induction. The power input 7 to the transmitter 4 can be wirelessly transmitted from the transmitter 4 to the receiver 6 to enable a power output 8 from the receiver 6 . The wireless transmission of energy is schematically indicated by arrow 11 .

[0044] In the example shown, the transmitter 4 is powered by a power s...

Abstract

The invention relates to a device (20) for a wireless power transfer system. The device (20) comprises a housing (21) and a coil (22) arranged inside the housing. The coil comprises a first conductorwire (23) forming a first sub coil (24) having a plurality of windings (25) and a second conductor wire (26) forming a second sub coil (27) having a plurality of windings (28). The housing (21) comprises a first holder (30) for accommodating and holding the first sub coil (24) and a second holder (31) for accommodating and holding the second sub coil (27). The first holder and the second holder are attached to each other such that the first sub coil (24) and the second sub coil (27) together form the coil (22) being arranged between the first holder (30) and the second holder (31).

Description

technical field [0001] The present invention relates to a device for a wireless power transmission system and a method for manufacturing the device for a wireless power transmission system. Furthermore, the invention relates to a vehicle comprising such a device. Background technique [0002] Electric vehicles and plug-in hybrid vehicles can be charged wirelessly through induction coils. Typically, a first coil of the transmitter is arranged on the floor or ground beneath the vehicle and a second coil of the receiver is arranged under the vehicle. There are many different coil topologies that can be used to transmit power. In addition to efficiently transferring power, small size coils and coils that allow large positioning tolerances between the transmitter and receiver coils are generally preferred. This in turn complicates the manufacture of the coil and its assembly into the housing. As the power transferred through wireless charging continues to increase, more coils...
