Embodiment Construction

[0101] figure 1 The use of a wireless power transfer arrangement according to the invention for charging a traction battery 11 of a vehicle is shown. In this example, the vehicle is a forklift 10 electrically driven by an electric motor 13 .

[0102] The primary side of the wireless power transfer arrangement comprises a wall box 1 and a primary pad 2 . The wall box 1 is mounted on a wall 7 of a house 5, such as eg a garage, car port, charging station, parking area or the like. The wall box 1 is connected to the electricity supply network 6 of the premises 5 from which the wall box 1 receives energy to be delivered to the vehicle. The primary pad 2 is mounted on or near another wall 8 of the house 5 and is connected to the wall box 1 by means of a fixed cable 3 . The primary pad 2 may be partially or fully integrated into the wall 8 so that it will require less or no additional space near the wall 8 . The primary pad 2 can also be mounted on the same wall 7 as the wall box...

Abstract

A wireless power transfer arrangement (20) for a wireless power transfer across an airgap (9) by inductive coupling, for example for charging the battery (31) of an electric vehicle, includes a primary side (21) with a primary pad (22) for generating a magnetic field (28) into the airgap (9) and a secondary side (24) arranged on the other side of the airgap (9) that picks up the magnetic field (28) and provides the energy received through the magnetic field (28) to the battery (31). The primary side (21) is for example installed at a charging station and the secondary side (24) is comprised by the electric vehicle. In order to control the charging process during the power transfer, a wireless communication channel (38) is provided between the primary (21) and the secondary (24) by means of two wireless transceivers (35, 36). According to the invention, the wireless transceivers (35, 36) are adapted such that their communication range is less than twice a largest spatial extent of the primary pad. In this way, the communication between the charging station and the vehicle may not be received by other charging stations or vehicles located at the same charging area. And if the other vehicles and other charging stations of the same charging area are adapted according to the invention as well, their communication does not interfere with each other or otherwise disturb each other in another way such that a complex and laborious pairing process may be avoided.

Description

technical field [0001] The invention relates to a wireless power transfer arrangement for wireless power transfer across an air gap by inductive coupling for charging an energy storage device of an electric vehicle, wherein the wireless power transfer arrangement comprises a primary unit comprised by the electric vehicle A secondary unit and a controller for controlling power transmission, the primary unit includes a wireless transceiver and a primary pad for inducing a magnetic field into the air gap, the secondary unit includes a wireless transceiver and a A secondary pad for power, a wireless transceiver includes an antenna for transmitting and receiving communication signals and is adapted to provide a wireless communication link between the primary unit and the secondary unit. Background technique [0002] Electric vehicles (EVs) have become increasingly popular. The term electric vehicle may for example include motor vehicles such as cars, trucks, motorcycles, trains,...
