Description and Operation

The wireless charging system receives battery voltage while in ACC or IG ON and transmits 5 W output power to a mobile phone. Mobile phones certified to the WPC (Qi 1.1.2) wireless charging standard or equipped with an exclusive wireless charging case are supported.
  1. Power receiver: Built into the secondary coil to receive induced current from the charging pad.
  2. Charging pad: Electric coils are wound inside a plastic cover.
  3. Coil: Rectangular and round coils generate various electromagnetic fields.
    A. Supply power to the charging pad to generate an electromagnetic field in the coil.
    B. The current induced by electromagnetic induction is directed to the power receiver to charge the battery.
  4. Instrument Cluster: Mobile phone contact warning
  5. BCM: Detects communication with the mobile phone
  6. Wireless charging indicator: Displays the charging status
  7. SMK unit: Stops charging during LF activation
  8. Charging Function
    1. Activation Method
      a. Close all vehicle doors.
      b. Turn the vehicle power to ACC or IG ON.
      b. Place a wireless charging-compatible mobile phone on the tray.
    2. Charging Status Display
      Mode Charging LED Display Notes
      Charging Ready LED off
      Charging in progress Yellow LED on
      Charging complete Green LED on
      Charging error Yellow LED flashing
      • Flashes 10 times over 10 seconds, then the LED turns off for 50 seconds (60 seconds total)
  9. Mobile Phone Contact Warning
    1. Activation Method
      a. Key OFF while charging the mobile phone.
      b. Checks whether the mobile phone is connected to the wireless charging unit.
      b. A warning message for mobile phone contact is displayed on the instrument cluster (approximately 4–5 seconds).
  10. Overheating Prevention
    1. Activation Method
      a. If the temperature of the thermistor inside the wireless charging module rises above a specified level (158 °F (70 °C)), charging stops to protect the mobile phone battery.
      b. If the thermistor temperature drops below a specified level (149 °F (65 °C)), charging resumes.
  11. Foreign Object Detection
    1. Charging stops if a coin or other metal object is between the wireless charger and the mobile phone. [Foreign Object]
    2. After the system detects a foreign object and stops charging the mobile phone, charging resumes approximately 60 seconds after the foreign object is removed.
  12. SMK Frequency Interference Prevention Unit: This function prevents interference between the wireless charging frequency and the smart key frequency band.
    1. Wireless charging stops when a door is open or the SMK unit is in LF mode (smart key search). For example, the wireless charging function stops if the driver takes the smart key out of the vehicle while the ignition is on.
    2. It returns to normal operation when the LF mode of the SMK is finished.
  13. Turn the wireless charging function on or off using the USM.
    ※ The rear door is applicable to vehicle models equipped with wheels.
