Description and Operation

Description

Wireless Charging System

With the ignition in IG ON, battery voltage is supplied to the wireless charging system to transmit 5 W of power to the mobile phone.

Mobile phones certified to the WPC (Qi 1.2.4) wireless charging standard, or those used with an exclusive wireless charging case, can be used.

Wireless Charging System Block Diagram

  1. Vehicle power supply.

  2. Convert to AC. Generate an electromagnetic field in the 1st coil.

  3. Generate induced current in the power receiver by electromagnetic induction.

  4. Generate AC current in the 2nd coil.

  5. Convert to DC.

  6. Charge the battery.

System Configuration Diagram

  1. Instrument cluster: Mobile phone contact alerts.

  2. Wireless charging indicator: Displays the charging status.

  3. Wireless Charging (WPC): Mobile phone mishandling, Foreign Object Detection (FOD).

  4. Intelligent Body Control Unit (IBU): Stops charging during low frequency (LF) activation.

Wireless Charging System Basic Functions

  1. Charging Function

    1. Activation Method

      a.

      Close all vehicle doors.
      b.

      Turn the vehicle power to IG ON.
      b.

      Place the mobile phone with wireless charging function on the tray.

    2. Charging Status Display

      Mode Charging LED Display NOTE
      Charging Ready LED off
      Charging in progress Yellow LED on
      Charging complete Green LED on
      Charging Error
      (FOD / High Temperature)      		 Yellow LED flashing

      • The yellow LED flashes (500 ms on / 500 ms off).

      • FOD detection: Flashes 10 times and stops for 50 sec → rechecks FOD status.

      • High temperature: Flashes 10 times when not charged due to high temperature. The LED turns off until the ERROR message is cleared.

  2. Mobile Phone Left Behind Alert Function

    1. Activation Method

      a.

      Ignition is turned off while the phone is still charging.
      b.

      Check whether the phone is on the wireless charging pad.
      b.

      A warning message is displayed if the phone is left on the WPC charging pad and the driver's door is open, or if the phone is left for more than 1 minute.

  3. Overheating Prevention

    1. Activation Method

      a.

      If the thermistor temperature inside the wireless charging module rises above a set level (158 °F (70 °C)), charging stops to protect the mobile phone battery.
      b.

      After the thermistor temperature drops (LED off until the high temperature ERROR is reset), charging resumes.

  4. Foreign Object Detection

    1. Charging is interrupted if coins or other metal objects are present between the wireless charger and the mobile phone.

      [Foreign Material]

    2. When the system detects a foreign object and charging stops, wireless charging resumes immediately after the foreign object is removed.

  5. Low Frequency (LF) Interference Prevention of IBU

    This function prevents interference between the wireless charging frequency and the smart key frequency band.

    1. Wireless charging stops when the door is open or the IBU is in LF (smart key search) mode.

      For example, the wireless charging function stops if the driver carries the smart key out of the vehicle while the ignition is on.

    2. It returns to normal operation when the IBU LF mode ends.

  6. Turn the wireless charging function on or off using the USM.

    ※ The rear door is applicable to vehicle models equipped with wheels.

Wireless Charging System (WPC) Protection

Item Condition Status
Protects against low/high voltage Protects and stops charging when voltage is below 8.5 V or above 16.5 V. LED is off
(stops operation)
Charging from 9 to 16 volts
Protects against reverse voltage Protects and stops charging in case of reverse voltage LED is off
(stops operation)
Protects against overcurrent Protects and stops charging if 4 amperes is detected. Yellow LED flashing
Protects against overheating Protects and stops charging when the internal temperature sensor of the wireless charging module detects 158°F (70°C) Yellow LED flashing
Resumes when temperature is below 149°F (65°C)
Foreign object
(coins, paper clips, precious metals, etc.)		 Protects and stops charging when a foreign object is detected (overheating prevention) Yellow LED flashing
Prevents frequency interference Protects and stops charging by activating the IBU if a door or the trunk is open. LED is off
(stops operation)
Resumes 3.5 seconds after all doors and the trunk are closed and IBU operation is completed.
Mobile Phone Contact Warning If a smartphone is on the charging pad when a door is opened after the ignition is OFF. Displays a warning message on the instrument cluster (approx. 4 seconds).

※ The rear door is applicable to vehicle models equipped with wheels.

Repair Procedures

Inspection

  1. Body electrical system malfunctions can be diagnosed more quickly using the Kia Diagnostic System (KDS).

    KDS provides the following information.

    1. Self-diagnosis: Checks and displays diagnostic trouble codes (DTC).

    2. Data list: Checks the input/output values of the system.

    3. Active test: Checks the operating condition of the system.

    4. Additional functions: System option control, zero point adjustment, and other functions.

  2. To diagnose the vehicle with diagnostic equipment, select "Vehicle Model" and "Wireless Charger System" to be checked.

  3. To check the current input/output values, select "Sensor Data" from the menu.

    The input/output sensor values corresponding to the selected module can be checked.

  4. To forcibly activate the selected module input, select "Actuation Test".

  5. To determine the cause of a fault in each module using self-diagnosis, select "Diagnostic Trouble Code".
