Charging Stopped. Check the AC charger
Hyundai Charging Stopped. Check the AC charger: car AC fault
Risk level
Medium
Proceed carefully and stop if the check is unclear.
Urgency
Medium
Quick answer
On a Hyundai EV (Kona Electric SX2 EV, Ioniq 5, or Ioniq 6), 'Charging Stopped. Check the AC charger' means charging stopped because of an external charger problem or a damaged charging cable. Check the external charger and connector connection without touching the metal contacts.
Safety first
Stop and check this first
- Never touch the charging connector of the charging cable or the charging inlet of the vehicle, and immediately stop using any cable or plug that shows external damage or overheating.
- When using the portable charger (ICCB), match the charging current setting (6 A, 8 A, 10 A, or 12 A by holding the control box button for more than 2 seconds until it blinks and waiting 10 seconds to save) to the outlet output current (8-9 A for 6 A up to 14-16 A for 12 A).
Safe checks you can perform
- Check the external charger display or the ICCB 2-digit error code (E1-E9, F1-F8)
- Unplug and reconnect the charging connector until you hear a click
- Check Scheduled Charging settings and test with another authenticated charger
Leave these tasks to a qualified professional
- Do not attempt this professional task: Inspection of the vehicle charging inlet, lock actuator, and control pilot circuit
- Do not attempt this professional task: Testing or replacement of the genuine Hyundai portable charger (ICCB)
What a technician must be able to justify
Technician visit
These are the steps they must carry out and show you. Tick them as they work: if steps are skipped, do not accept a part swap.
These are not instructions for opening or handling the equipment yourself. They are the checks that should support a technical conclusion.
Inspection of the vehicle charging inlet, lock actuator, and control pilot circuit
What they doThe authorized Hyundai dealer inspects the charging inlet for external damage or foreign substances, tests the connector lock mechanism, and verifies control pilot communication with an authenticated charger.
They must show youthe condition of the charging inlet terminals and a live charging session running without interruption.
In writingthe charging inlet inspection findings, any stored vehicle fault codes, and verification with an authenticated charger.
Testing or replacement of the genuine Hyundai portable charger (ICCB)
What they doIf the portable charger (ICCB) continues to blink FAULT in red with error codes (E1-E9 or F1-F8) after resetting and matching the current level (6 A, 8 A, 10 A, or 12 A), the dealer tests the ICCB control box and temperature sensors.
They must show youthe ICCB error code diagnosis and normal charging operation with a verified genuine Hyundai portable charger.
In writingthe ICCB error code (E1-E9 or F1-F8), the tested charge level (6 A to 12 A), and the repair or replacement performed.
Before accepting a part or repair
Nothing has been shown yet. Do not accept a part swap based on the code alone.
Follow these steps
Note: Follow the documented order. An error code identifies the affected system, but it does not prove by itself which part has failed.
Check the external charger display or the ICCB 2-digit error code (E1-E9, F1-F8)
- Who:
- you, looking at the AC/DC charger screen or the portable charger (ICCB) control box.
- How:
- check whether POWER is green and FAULT blinks red on the ICCB (or CHARGE blinks due to plug or internal temperature limiting) and note any 2-digit code from E1-E9 or F1-F8; remember that after more than 1 minute with no status change, the ICCB enters power saving mode and turns off the display light.
- Result that matters:
- identify whether charging stopped because of the wall outlet, the external charger, or an internal ICCB error.
- If the ICCB shows F2 (poor grounding), E4/E5 (plug temperature), or E1/E2 (current leakage):
- reset the portable charger by disconnecting and reconnecting the power plug, then pressing the control box button for more than 2 seconds.
- If the same error or codes E3, E6, E9, F1, F3, F4, F5, F6, F7, or F8 recur after resetting the ICCB:
- stop using it and have the vehicle and charger inspected by an authorized Hyundai dealer.
- Evidence to keep:
- photo of the ICCB control box showing the 2-digit code or the external charger error screen.

Unplug and reconnect the charging connector until you hear a click
- Who:
- you, with the vehicle turned off in P (Park) and the Electronic Parking Brake (EPB) applied.
- How:
- if the connector lock is set to Always or While Charging, unlock the door with the smart key or driver's door button (or to stop charging immediately, press the door lock/unlock button and within 15 seconds press and hold the charging button inside the charging door for more than 2 seconds), inspect for damage or dust, and push the connector handle all the way in until it clicks.
- Result that matters:
- rule out a loose or drooping connector or a pressed unlock button.
- If you find dust or contaminants on the connector or inlet:
- clean them using an air gun without ever touching the charging connector or charging inlet contacts.
- If you see external damage on the charging cable, connector, or inlet:
- do not charge and visit an authorized Hyundai dealer.
- Evidence to keep:
- photos of the charging connector, charging inlet, and instrument cluster warning message.

Check Scheduled Charging settings and test with another authenticated charger
- Who:
- you, via the infotainment screen and at a second authenticated charger.
- How:
- check Electric Vehicle > AC Charger > Scheduled Charging (or hold the charging button inside the charging door for more than 2 seconds to charge immediately) and test charging with another authenticated AC charger or a genuine Hyundai portable charger.
- Result that matters:
- determine whether the fault is isolated to the first charger or stays with the vehicle.
- If the vehicle charges normally with another authenticated charger:
- contact the first charger manufacturer to resolve the station issue.
- If the vehicle still does not charge with another authenticated charger or genuine Hyundai portable charger:
- have the vehicle inspected by an authorized Hyundai dealer.
- Evidence to keep:
- photo of the Scheduled Charging screen and the charging test result at the second charger.

What it means
In the Hyundai Kona Electric (SX2 EV) owner's manual, the instrument cluster displays 'Charging Stopped. Check the AC (DC) charger' when charging stops due to a problem with the external AC or DC charger, because the external AC charger stopped charging, or because the charging cable is damaged; if the connector is not seated properly or its unlock button is pressed, 'Charging Stopped. Check the cable connection' appears. On the portable charger (ICCB), the FAULT lamp blinks red with a 2-digit code (E1 to E9 or F1 to F8). The message alone never proves whether the fault is in the charger, the cable, or the vehicle inlet.
Warnings and stop conditions

Symptoms and causes
Probable causes · in order
- External AC or DC charger fault, charger stop, or household outlet problemCommon
Hyundai's manual states that this message appears when there is a problem with the external AC or DC charger or the external AC charger stopped charging; on the portable charger (ICCB), FAULT blinks red with codes such as F2 (poor outlet grounding), E1/E2 (current leakage), E4/E5 (plug temperature), E7 (overcurrent), or E8 (charger overheating).
Evidence: Hyundai Kona Electric (SX2 EV) 2025 owner's manual: checking electric vehicle driving information · Hyundai Kona Electric (SX2 EV) 2025 owner's manual: using a portable charger (ICCB)
- Charging connector not properly connected to the inlet or unlock button pressedCommon
If the charging connector is not pushed into the inlet until it clicks, droops or vibrates, or has its unlock button pressed, charging stops with 'Charging Stopped. Check the cable connection' or ICCB control pilot voltage errors F5/F6.

- Damaged charging cable or active Scheduled Charging settingPossible
External cable damage or dust in the inlet interrupts charging; also, if Scheduled Charging is set under Electric Vehicle > AC Charger > Scheduled Charging, the cluster shows 'Waiting to charge at scheduled time' instead of starting immediately.
