Picture 1: System configuration
System overview
Wireless charging controller <LP, MP> – System for charging mobile phones wirelessly in-vehicle using electromagnetic induction between coils
- After inputting IGN1 power, the reception coil (cell phone RX Coil)
- Confirmation of non-mobile NFC mounting via NFC Multi Tagging <MP + NFC>
- (TX side charging pad: wireless charger side) Current flows in the transmission coil
- The magnetic field generated by the current of the transmission coil is guided to the receiving coil and induction current is generated in the receiving coil
- The charging current starts to be charged through the PMIC (Power module IC) of the mobile phone
NFC Communication Controller <MP + NFC> – Vehicle start, key registration, and vehicle information transmission/reception device through mutual communication with NFC (near field communication) installed in mobile phone and ECU.
- After inputting B + power put Smart Phone on top of ECU
- When charging C_WPCNFCCmd = 0x01 (NFCSearchingOnHCE) from the authentication unit, stop wireless charging && NFC Start
- PhoneKeyAuth Mode (SmartPhone ↔ WPC ↔ IAU AUTH certification)
- RTC SYNC MODE (RTC synchronization)
- CertificateChain SYNC MODE (Certificate Synchronization)
- PhoneKey Sync MODE MODE (Synchronize PhoneKey and Spare Key)
- When C_WPCNFCCmd = 0x02 (NFC Searching Off) is input from the authentication unit NFC Mode Stop && When IGN1 is ON, Wireless charging Start

FCC warning statement:
15.19
λ. This device complies with Part 15 of the FCC Rules. Operation is subject to
the following two conditions:
(1) this device may not cause harmful interference, and (2) this device must
accept any interference received, including interference that may cause
undesired operation.
15.105
This equipment has been tested and found to comply with the limits for a Class
B digital device, pursuant to part 15 of the FCC Rules. These limits are
designed to provide reasonable protection against harmful interference in a
residential installation. This equipment generates, uses and can radiate radio
frequency energy and, if not installed and used in accordance with the
instructions, may cause harmful interference to radio communications. However,
there is no guarantee that interference will not occur in a particular
installation. If this equipment does cause harmful interference to radio or
television reception, which can be determined by turning the equipment off and
on, the user is encouraged to try to correct the interference by one or more
of the following measures:
- Reorient or relocate the receiving antenna.
- Increase the separation between the equipment and receiver.
- Connect the equipment into an outlet on a circuit different from that to which the receiver is connected.
- Consult the dealer or an experienced radio/TV technician for help.
15.21
- Any changes or modifications not expressly approved by the party responsible for compliance could void the authority to operate the equipment.
- This device and its antenna must not be co-located or operating in conjunction with any other antenna or transmitter.
- End-users and installers must be provided with antenna installation instructions and transmitter operating conditions for satisfying RF exposure compliance.
FCC/ IC RF Radiation Exposure Statement:
This equipment complies with FCC/ISED radiation exposure limits set forth for
an uncontrolled environment. This equipment should be installed and operated
with a minimum distance of 15cm between the radiator & your body.
This device complies with FCC/ ISED radiation exposure limits set forth for an
uncontrolled environment.
IC warning statement:
RSS-Gen Issue 4 8.4
This device complies with Industry Canada’s license-exempt RSSs. Operation is
subject to the following two conditions: (1) This device may not cause
interference; and (2) This device must accept any interference, including
interference that may cause undesired operation of the device.
