Description and operating principle
| Description and Operation |
Wireless Power Charger System
During ACC or IG ON, battery voltage is supplied to the wireless power charger
system to transmit an output of 5 W to mobile phone.
Mobile phones certified with the wireless charging standard WPC (Qi 1.1.2) or
equipped with an exclusive wireless charging case can be used.
| •
|
WPC : Wireless Power Consortium
|
| •
|
Qi 1.1.2 : refers to certified product with the capability to
transmit power of up to 5 W and detect metal and other impurities
to prevent heating.
|
|
|
1. |
Power receiver : embedded with the secondary coil designed to receive
the induced current from the charging pad.
|
|
2. |
Charging pad : electrical coils wound inside the plastic cover.
|
|
3. |
Coil : Rectangular and circular coils generate diverse electromagnetic
fields.
| A. |
Connect power to the charging pad to generate electromagnetic
fields in the coil.
|
| B. |
Current induced from electromagnetic induction phenomenon is
sent to the power receiver to charge the battery.

|
|
|
|
3. |
Overheating prevention
|
(1) |
Activation method
|
a. |
If the thermistor temperature inside the wireless charging
module rises above a certain level (158 °F (70 °C)),
charging will stop to protect the mobile phone battery.
|
• |
The amber LED of the charging display
lamp blinks 10 times for 10 seconds,
and then it is turned off for 50 seconds
(total 60 seconds).
|
|
• |
The process is repeated for every 60
seconds.
|
|
|
|
b. |
If the thermistor temperature falls below a certain
level (149 °F (65 °C)), charging will restart.
|
When the charging function is restarted, the
amber LED of the charging display lamp will
be turned on.
|
|
|
|
|
4. |
Foreign matter detection
|
(1) |
Charging will be stopped if there is a coin or other metallic
object between the wireless charging unit and the mobile phone.
[Foreign matter]
|
• |
Foreign matter : All metallic objects such as
coins, clips, and precious metals
|
|
• |
The amber LED of the charging display lamp blinks
10 times for 10 seconds, and then it is turned
off for 50 seconds (total 60 seconds).
|
|
• |
The process is repeated for every 60 seconds.
|
|
|
Be careful as touching the foreign matter by hand may
cause burns.
|
|
|
(2) |
After the system has detected foreign matter and stopped charging
the mobile phone, the charging will resume in about 60 seconds
once the foreign matter has been removed.
|
When the charging function is restarted, the amber LED
of the charging display lamp will be turned on.
|
|
|
|
5. |
SMK unit LF frequency interference prevention
This function prevents interference between the wireless charging frequency
and smart key unit frequency band.
|
(1) |
Wireless charging is stopped when the door is open or the SMK
unit is in LF mode (searching for smart key).
e.g. Wireless charging function is stopped if the driver carries
the smart key out of the vehicle during IG ON.
|
Charging will stop and the amber LED of the charging
display lamp will turn off.
|
|
|
(2) |
It will return to normal operating status when the LF mode of
the SMK unit is completed.
|
|
|
6. |
Turn the wireless charging function ON/OFF with USM.
※ Tailgate applies to RV vehicle models.

R-1. Check the wireless power charger system operation
|
1. |
If the placement of a mobile phone is not detected
|
(1) |
If the internal temperature of the mobile phone battery is high,
the mobile phone itself turns "OFF" the power.
|
The temperature at which the power is automatically
turned "OFF" differs by mobile phone model.
|
|
|
(2) |
If the mobile phone was placed outside the charging range
|
|
(3) |
If the mobile phone was placed by its LCD side on the charging
pad surface (if the phone was placed upside down)
|
|
(4) |
If the mobile phone was turned 180°
|
|
|
2. |
Check that the amber LED of the wireless charging lamp turns on when
the mobile phone is in normal condition and is correctly placed.
|
R-2. Check for overcurrent, overheating and foreign matter
|
1. |
Overcurrent : Charging stops in overcurrent of over 4.5 A
|
(1) |
The overcurrent error status will be reset when the current
falls under 4.5 A or when ACC is turned off and on.
|
|
|
2. |
Overheating : The unit will be automatically turned "OFF" when the internal
temperature of the wireless charging unit is over 158°F (70°C).
|
(1) |
The error status will be reset when the internal temperature
of the wirelss charging unit falls under 149°F (65°C).
|
|
|
3. |
Foreign matter : When metallic objects such as coins, clips and precious
metals are detected, charging will be stopped to prevent overheating.
|
(1) |
Error status will be reset when foreign matter is removed.
|
|
• |
The amber LED of the charging display lamp blinks 10
times for 10 seconds, and then it is turned off for
50 seconds (total 60 seconds).
|
|
• |
The process is repeated for every 60 seconds.
|
|
• |
Turning ACC OFF/ON resets the error status and returns
