The inductive power supply systems provide electrical power transfer without sparking effects due to contact problems and the inductive power systems are rugged against dust and environmental conditions.
The inductive transfer of electric power to an electrical device is based on the use of an alternating magnetic field generated by a secondary coil inductively coupled to a primary coil. Thus, electrical power is wirelessly transferred to the secondary coil without moving parts.
Current inductive power systems do not include devices and methods for protecting the use of the inductive power supply system by non-registered and illegal users thereof. This can lead to the abuse of electrical devices which receive electrical power from an inductive power supply system.
The prior art device does not describe using a secure vehicle inductive power supply system for supplying electrical power to an electrical device located in the vehicle.
The present disclosure provides systems and methods for securely transferring electrical power inductively from an inductive power transfer system to an electrical device, in a motorized vehicle. The present disclosure includes, inter alia, a communications security system which is configured to establish a secure communications channel between the inductive power transfer system and the electrical device. The secure communications channel ensures that only registered and legal users of the motorized vehicle and/or the electrical device are enabled to transfer electrical power and confidential data, such as confidential business data and personal financial data, between the inductive power supply system and the electrical device. The secure communications channel prevents pirate and illegal users for transferring electrical power to the electrical device as well as obtaining access to the confidential data and misusing the data, which are stored in the electrical device.
Typically, the electrical device includes, inter alia, devices, such as a mobile communications device, a vehicle inductive power transfer container, a vehicle inductive thermal cup, a vehicle onboard fan, a navigation system, a hands-free microphone, a computing device, such as a laptop computer, a fluid cooling unit and any combination thereof.
In order to execute the transfer of electrical power and data, the communications secure system establishes a secure communications channel between the inductive power supply system and the electrical device by using a handshaking procedure. The handshaking procedure is typically performed by using a secure handshaking protocol, such as a Bluetooth protocol or a WiFi protocol.
The inductive power transfer system, which is electrically coupled to a vehicle power supply interface, provides electrical power to the inductive power transfer system. The inductive power supply system includes, inter alia, an inductive power outlet unit, which is associated with the vehicle, is inductively coupled to an inductive power receiver unit. The inductive power receiver unit is associated with the electrical device.
The inductive power outlet unit, which includes, inter alia, a primary coil and a driver unit of the power supply, is integrated to the vehicle charging frame. An inductive power supply unit including, inter alia, a secondary coil is inductively coupled to the primary coil of the power outlet unit upon activating the vehicle power supply interface. The vehicle power supply interface supplies electrical power to the inductive power transfer system which establishing an inductive magnetic circuit between the inductive power outlet unit and the inductive power supply unit.
Alternatively, the inductive magnetic coupling and the inductive magnetic circuit is established upon installing the electrical device in the vehicle charging frame.
In order to provide a secure communications link between the inductive power transfer system and the electrical device upon activating the inductive power transfer system, the communications security system initiates the handshaking procedure between the inductive power transfer system and said electrical device.
In order to perform the handshake procedure, Near-Field Communication (NFC) tags are associated with the inductive power supply system and the electrical device. A first NFC tag is associated with the inductive power transfer unit and a second NFC tag associated with the electrical device. The first NFC tag and the second NFC tag perform the handshaking procedure between said inductive power supply system and said electrical device.
In order to proceed with the handshaking procedure, typically, the first NFC tag performs a Bluetooth search procedure seeking a corresponding Bluetooth device in order to perform a pairing relationship.
If the handshaking procedure is successful, the communications security system establishes the secure communications channel between the power transfer system and the electrical device. The inductive power transfer system commences to supply electrical power to the electrical device. In addition, transfer data, such as confidential personal and financial, which are typically stored in the electrical device, are transferred between the electrical device and the vehicle. The data transfer is performed using a secure Bluetooth communications channel or a secure WiFi communications channel.
On establishment of the secure communications channel and the transfer of data between the electrical device and the power transfer supply system, a user and/or driver is enabled to perform various additional functions.

Optionally, the switching unit 52 is located on the dashboard of the vehicle 12 permitting easy operation of the power assembly 10 without distracting the driver's attention from driving the vehicle 12.
On activation of the activation unit 50 by the driver/user, the activation unit 50 forwards a commencement-of-operation signal 54 to the communications security system 14 via a communications link 56.
On reception of the signal 54 at the communications security system 14, the communications controller 28 initiates a handshake procedure 37 between the NFC1 30 and the NFC2 32 by forwarding a handshake protocol to the NFC1 30 and the NFC2 32 via the communications channels 19 and 34. A recognition protocol exchange 60 commences.
Following a successful handshake procedure 37, a secure link 62 is established between the inductive power transfer system 18 and the electrical device 20 by the communications link 17.

The secure communications channel 134, the secure communications channel 146 and the secure communications channel 148 ensure that all communications between the inductive power transfer system 118 and the electrical device 204 are secure in accordance with a secured protocol, such as a Bluetooth protocol. Thus, misuse of the vehicle inductions power assembly 110 by pirate users is prevented.
The secure communications channel 116 is a Bluetooth communications channel and the handshaking procedure 136 uses a secure Bluetooth protocol. Alternatively, the secure communications channel 116 and a corresponding protocol are selected from the group consisting of a WiFi communications channel, a LAN network channel and an Ethernet network channel.
The communications security system 114 also includes a data-transfer signal generator 138 for generating requisite signals for operating the inductive power transfer system 118, as described below. In addition, the data-transfer signal generator 138 generates a data-transfer commencement signal 140, a data-transfer proceeding signal 142 and a data-transfer termination signal 144, which are displayed to the user of the power transfer system 118 by at least one peripheral display device 170, as described below.
The vehicle induction power assembly 110 includes an activation unit 150 for activating the power transfer system 118. The activation unit 150 is activated by the user of the power assembly 110 by operating a switching unit 152. The switching unit 152 includes an input device, such as an electro-mechanical switch, a keyboard, a keypad, a mouse, a touch screen, a pen device a character recognition device, an optical recognition device, a voice recognition device and any combination thereof.
Optionally, the switching unit 152 is located on the dashboard of the vehicle 112 permitting easy operation of the vehicle induction power assembly 110 without distracting the user attention from driving the vehicle 112.
On activation of the activation unit 150 by a user, the activation unit 150 forwards a commencement-of-operation signal 154 to the communications security system 114 via a communications link 156.
On reception of the signal 154 at the communications security system 114, the communications controller 128 initiates a handshake procedure 137 between the NFC1 130 and the NFC2 132 by forwarding a handshake protocol to the NFC1 130 and the NFC2 132 via the communications channels 119 and 134. A recognition protocol exchange 160 commences.
Following a successful handshake procedure 137, a secure link 162 is established between the inductive power transfer system 118 and the electrical device 120 by the communications link 117. The communications controller 128 instructs the data-transfer signal generator 138, via a communications link 139, to generate a data-transfer commencement signal 141 for forwarding to the inductive power transfer system 118 via the communications channel 154 to the activation device 150.
Upon receiving the data-transfer commencement signal 141, the activation device 150 forwards an operation-commencement signal 164 to the vehicle power supply interface 158, via a communications channel 166 and the vehicle power supply interface 158 provides electrical power 168 to the inductive power transfer system 118 for operation of the power transfer supply system 118. The power transfer system 118 proceeds to supply electrical power to the inductive container 200.
Concomitantly with the generation of the data-transfer commencement signal 141, the generator 138 also generates a further data-transfer commencement signal 140 for forwarding to the peripheral display device 170.
In order to terminate the operation of the power transfer supply system 118, the user deactivates the device 150 by appropriately operating the switching unit 152. The switching unit 152 forwards a stop-supply signal 159 to the vehicle power supply interface 158 and the supply interface 158 ceases to apply electrical power to the power outlet unit 123 and the supply of electrical power to the container 200 terminates.
Additionally or alternatively, termination of the supply of electrical power to the container 200 is achieved by a safety monitoring device 153 continually monitoring the operation of the power transfer supply system 118. If the monitor 153 senses that the electrical and/or temperature safety features of the system 118 are exceeded, the monitor device 153 ceases the operation of the power transfer supply system 118 by means of a communication link 149. In addition, the monitor 153 forwards an appropriate visual/audio warning signal 147 to the display unit 212, via the communications link 149 of the container 200 as well as to the display device 170, via a communications link 174.
Furthermore, termination of the supply of electrical power to the electrical device 204 is achieved by the user removing the platform 202. The removal of the electrical device 204 is detected by a contact sensor 207, located on the platform 202. The container 200 forwards a break-contact signal 163 to the data-transfer controller 128 via the communications link 165. The communications controller 128 instructs the data-transfer signal generator 138 to generate a data-transfer termination signal 145. The generator 138 forwards the signal 145 to the activating device 150, via the communications channel 154. On reception of the data-transfer termination signal 145, the activating device 150 instructs the vehicle supply interface 158 to cease applying electrical power to the power outlet unit 123 and the power supply interface 118 ceases operation. The generator 138 also forwards a termination signal 144 to the display 204 and the peripheral device 170.

It is appreciated that the visual display system 178 operates asynchronously or concomitantly with the audio notification system 180.
In order for the user to be informed of the required information, such as the operational status of the power assembly 110, the user activates the requisite key or keys on the switching unit 152. Upon the user selecting the appropriate key or keys, the communications security system 114 establishes the secure communications channel 171 between the container 200 and the communications notification device 176.
In accordance with the user's instructions, the multiplexer 183 selects the appropriate member and/or members of the communications notification device 176.

The inductive power transfer unit 318 includes at least one primary inductor 321 and at least one driving unit 322 associated within an inductive power outlet unit 323. The power outlet unit 323 is associated with a vehicle charging frame and is inductively operable to generate a varying electrical potential across the at least one primary inductor 321 so as to inductively couple 324 the at least one primary inductor 321 with a secondary inductor 326 of an inductive power receiver unit 327. The inductive power transfer unit 318 is coupled to a thermoelectric unit 328 associated with the thermal cup 314 by means of an electrically conductive link 330. The power unit 318 provides electrical power to the thermal cup 314 for heating/cooling of a beverage 332 contained in the beverage container 316, which is placed in the thermal cup 314.
The vehicle induction power assembly 310 includes an activation unit 350 and a switching unit 352 for activating the power transfer system 318. The activation unit 350, which is associated with the vehicle 312, is activated by the user of the power assembly 310 operating the switching unit 352. The switching unit 352 includes an input device 351 for activating the unit 350. The user selects on the activating unit 350 the required operation of the thermal cup 314, either heating the beverage 332, cooling the beverage 332, maintaining the beverage 332 temperature at a required beverage temperature and/or maintaining the beverage 332 at its current temperature.
Optionally, the activation unit 350 and the switching unit 352 are located on the dashboard of the vehicle 312 permitting easy operation of the thermal cup 314 without distracting the user attention from driving the vehicle 312.
A visual/audio notification device 351 is connected to the activation device 350 and is Optionally located on the dashboard of the vehicle 312. The device 351 notifies the user of the operational status of the thermal cup 314, the temperature of the beverage 332 or whether the heating operation, the cooling operation or the temperature maintaining operation was selected.
On activation of the activation unit 350 by a user, the activation unit 350 forwards a commencement-of-operation signal 354 to a vehicle power supply interface 358 to commence supplying electrical power 368 to the inductive power transfer system 318. The power transfer system 318 proceeds to supply electrical power to the thermoelectric element 328. A thermostat 329 located between an inner wall of the thermal cup 314 records the temperature of the beverage container 316, adjusts the recorded temperature for the heat transfer across the beverage container 316 and forwards this information to the user notification device 351.
If the recorded temperature is compatible with the user required temperature, the device 351 forwards an appropriate signal 357 to the activation unit 350. The activation unit 350 forwards a stop-supply signal 359 to the supply interface 358 and the supply interface 358 ceases to apply electrical power to the power outlet unit 323 and the supply of electrical power to the thermal cup 314 terminates.
The thermostat 329 continually checks the beverage temperature. If the recorded temperature changes from the required temperature, the thermostat 329 forwards an appropriate signal to the activation device 350. The activation device 350 forwards a further commencement-of-operation signal to the power interface 358 and the heating/cooling process recommences. The activation device 351 appropriately notifies the user thereof.
The power transfer system continues to supply electrical power to the thermal cup 314 until the recorded temperature is compatible with the selected temperature.
Alternatively, the user deactivates the device 350 by appropriately operating the switching unit 352 and the device 350 forwards a stop-supply signal 359 to the vehicle power supply interface 358.
Additionally or alternatively, termination of the supply of electrical power to the thermal cup 314 is achieved by a safety monitoring device 353 which continually monitors the operation of the power transfer supply system 318. If the monitor senses that the electrical and/or temperature safety features of the system 318 are exceeded, the monitor device 353 ceases the operation of the power transfer supply system 318 and forwards an appropriate visual/audio warning signal 347 to the activation unit 350 as well as to the display unit 351.
Furthermore, termination of the supply of electrical power to the thermal cup 314 is achieved by the user removing the beverage container 316 from the thermal cup 314. The removal of the beverage container 316 is detected by a contact sensor 367, located on the inner wall of the thermal cup 314. The cup 314 forwards a break-contact signal 363 to the activation device 350 and the notification unit 351 notifies the user thereof. The activation device 350 generates and forwards the stop-supply signal 359 to the vehicle supply interface 358 to cease supplying electrical power 368 to the power outlet unit 323 and the power supply interface 318 ceases operation.
