• 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.
1)Connect power to the charging pad to generate electromagnetic fields in the coil.
2)Current induced from electromagnetic induction phenomenon is sent to the power receiver to charge the battery.
1.Instrument cluster : Alerts about contact with mobile phone
2.IBU unit : Determines contact with mobile phone
3.Wireless charging lamp : Displays the charging status
4.SMK unit : Stops charging during the activation of LF
1.Charging Function
(1)Activation method
a.Close all doors of the car.
b.Switch vehicle power to ACC or IG ON.
c.Place the wireless charging-enabled mobile phone on the tray.
(2)Charging status display
Mode | Charging LED display | Remarks | |||
Stand by for charging | LED turned OFF |
| |||
Charging in process | Amber LED turned ON |
| |||
Charging completed | Green LED turned ON |
| |||
Charging error | Amber LED blinks |

2.Alert for contact with mobile phone
(1)Activation method
a.Key OFF while the mobile phone is being charged.
b.Checks if the mobile phone is placed on the wireless charging unit.
c. Alert message for contact with mobile phone is displayed on the instrument panel (for about 4 - 5 seconds).
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.
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 : 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.
(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.
5.SMK unit LF frequency interference preventionThis 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.
(2)It will return to normal operating status when the LF mode of the SMK unit is completed.
