Hyundai IONIQ 5 Charging at REWE Charging

Hyundai IONIQ 5 Charger Will Not Start a Charging Session

You have plugged the cable into your IONIQ 5's charge port on the right rear fender, but nothing is happening. No power flowing, no charging animation on the cluster. This is frustrating, but it is rarely the car. Most failed charging starts come from the charger, the app, or a setting on the vehicle. Here is how to work through it.

Symptoms

• Charge port light does not turn on or blinks red after plugging in
• Charger screen shows an error or returns to the start screen immediately
• Charging app shows session failed or authentication error
• Cable is plugged in but the IONIQ 5 does not recognize the connection
• Charge port door will not open, especially in cold weather

What to Do

1. 1

   Open the charge port door

   Press the button on the charge port door on the right rear fender. If it will not open in cold weather, try pressing and holding the unlock button on your key fob, or gently warm the edges with your hands or lukewarm water. Do not force it open or use sharp tools.

2. 2

   Check for scheduled charging

   On the center touchscreen, go to EV settings and check if a charging schedule is active. You can also check in the Bluelink app under the charging section. Disable the schedule temporarily to charge immediately.

3. 3

   Unplug and reconnect the cable firmly

   Remove the cable completely, wait 10 seconds, and plug it back in. Push the CCS2 connector in until it clicks into the charge port. Make sure both the upper (AC) and lower (DC) sections are fully seated.

4. 4

   Re-authenticate at the charger

   Tap your RFID card again, restart the charging app, or try a different payment method. If the charger supports Plug and Charge and your IONIQ 5 has it enabled, try unplugging and replugging to re-trigger automatic authentication.

5. 5

   Try a different charger or stall

   If the session still will not start, the charger may be faulty. Move to a different stall at the same station. If all stalls fail, try a different charging station entirely.

6. 6

   Restart the car if needed

   In rare cases, the IONIQ 5's charging system needs a reset. Unplug the cable, sit in the car, press the start button to turn the car on, wait 30 seconds, turn it off, and try plugging in again.

Hyundai IONIQ 5 Charger Payment or Authentication Failed

You are at the charger, cable in hand, and the screen says payment failed or authentication error. Your IONIQ 5 is ready to charge, but the charger will not let you start. This is almost always a charger-side or app-side issue, not a car problem. Here is how to get charging.

Symptoms

• Charger screen shows payment declined or authentication error
• RFID card is not recognized when tapped on the reader
• Charging app shows session failed to start or payment error
• Contactless bank card is declined at the charger terminal
• Plug and Charge does not auto-authenticate after plugging in

What to Do

1. 1

   Check your charging app account

   Open your charging app and verify that your payment method is valid, your balance is sufficient (for prepaid accounts), and there is no stuck session from a previous charge. Update your payment method if the card on file has expired.

2. 2

   Try a different authentication method

   If your RFID card failed, try the app's QR code or start-via-app feature. If the app failed, try tapping your RFID card. If you have a contactless bank card, try that. Having at least two methods available saves time.

3. 3

   Check if Plug and Charge is enabled

   On the center touchscreen, go to EV settings and look for the Plug and Charge option. Make sure it is turned on. Then check if the charging network supports Plug and Charge. If both are set up, unplug the CCS2 cable and plug it back in to re-trigger authentication.

4. 4

   Restart the charger if possible

   Some chargers have a reset option on the screen or a physical button. If the charger seems stuck from a previous session, restarting it can clear the error. Check the charger screen for a reset or cancel option.

5. 5

   Move to a different charger

   If authentication keeps failing on one charger, try a different stall at the same station. Charger hardware varies even within the same location, and another unit may process your payment without issues.

6. 6

   Contact the charging network's support

   Most chargers display a phone number or support contact on the screen or on a sticker. Call or message the network's support to report the issue. They can sometimes remotely start a session or clear a stuck charger from their side.

Hyundai IONIQ 5 Charging Slower Than Expected at DC or AC

Your IONIQ 5 has one of the fastest charging architectures on the market. 800V, up to 233 kW, 10-80% in roughly 18 minutes. So when the screen shows 50 kW at a fast charger, something feels wrong. In most cases, slow charging on the IONIQ 5 is not a defect. It is usually the battery temperature, the charger's actual output, or a setting worth checking.

Symptoms

• DC fast charging speed well below the 233 kW maximum
• AC home or destination charging stuck at 3-4 kW instead of 11 kW
• Charging speed drops sharply after reaching 60-70%
• Charging session starts at low power and never ramps up
• Instrument cluster shows much lower power than the charger's rated output

What to Do

1. 1

   Check the battery temperature on the cluster

   Look at the charging information on your 12.3-inch instrument cluster or center touchscreen. If the battery temperature is low, consider driving for 15-20 minutes before your next charging stop, or use the built-in navigation to trigger battery preconditioning automatically.

2. 2

   Confirm the charger supports 800V

   Check the charger's specifications on its screen or the charging network's app. If it is a 400V charger, the IONIQ 5's multi-charging system will still work, but speeds will be lower than on an 800V unit. No adapter needed.

3. 3

   Check your state of charge

   If you are above 80%, the slowdown is expected. For the fastest road trip charging, plan stops so you arrive between 10-20% and unplug at 80%.

4. 4

   Check scheduled charging and charge limits

   Open the EV settings on the center touchscreen or in the Bluelink app. Make sure scheduled charging is not active (it can delay charging start) and the charge current limit is set to maximum.

5. 5

   Verify the charger is not sharing power

   Look at the charger unit. If two cables come from the same cabinet and someone is using the other one, you may be splitting power. Move to an unoccupied charger if available.

6. 6

   Try a different charger or station

   If the speed is still low after checking everything, the charger itself may be degraded or throttled. Try another stall at the same location, or head to a different station entirely.

Charger occupied by non-charging vehicles

You arrive at the REWE charger and a car is parked in the charging spot without being plugged in. This is common at supermarket locations where shoppers treat EV spots as regular parking.

Symptoms

• Charging spot is occupied by a car with no cable connected
• ICE vehicle parked in the EV charging bay
• Car is plugged in but session has clearly ended and the driver is inside shopping
• All charging spots taken despite the app showing the charger as available

How to Fix It

1. 1

   Check if the other car is actively charging

   Look at the charger display or connector. If the session has ended and the car is just parked, REWE cannot remotely move it. The app status reflects the charger, not the parking spot.

2. 2

   Ask at the REWE customer service desk

   REWE staff can sometimes make a store announcement asking the vehicle owner to move. This works more often than you would expect.

3. 3

   Wait briefly or shop first

   At supermarket chargers, turnover is high. Most shoppers leave within 30 to 45 minutes. Do your shopping and check again.

4. 4

   Check for additional REWE locations nearby

   Many German cities have multiple REWE stores with chargers within a short drive. Check the app for the next closest option.

Contactless card reader not responding

You tap your debit or credit card on the reader but nothing happens. The reader does not beep, does not show a light, or shows an error briefly before resetting.

Symptoms

• Card reader shows no response when you tap
• Reader beeps but the screen shows an error
• Card works at the REWE checkout inside but not at the charger
• Contactless symbol is visible on the reader but it seems inactive

How to Fix It

1. 1

   Hold your card flat against the reader for 3 to 5 seconds

   Some REWE charger readers are slower than store payment terminals. Hold the card still and wait for the full processing time.

2. 2

   Remove your phone and other cards from the area

   If you hold your wallet with multiple contactless cards near the reader, it may detect interference and reject the transaction.

3. 3

   Try the charging app instead

   If contactless is not working, start the session through the REWE charging partner app. This bypasses the physical card reader entirely.

4. 4

   Check if the reader is physically damaged

   Supermarket chargers are exposed to shopping carts, weather, and heavy foot traffic. If the reader looks cracked or the screen is damaged, report it to REWE staff inside and try another stall if available.

Session ends due to maximum stay time limit

Your charging session stops before the battery is full because REWE enforces a maximum parking time at the charging spot. This exists to keep spots available for other shoppers.

Symptoms

• Charging stops after 60 to 90 minutes even though the battery is not full
• App notification says session ended due to time limit
• You return from shopping to find the charger disconnected
• Charger screen shows session completed despite low battery level

How to Fix It

1. 1

   Check the posted time limit before you start

   REWE typically allows 60 to 120 minutes depending on the location. Look for signage near the charger or check the app for time restrictions at that specific store.

2. 2

   Plan your charge around your shopping time

   At up to 300 kW, most EVs can gain 150 to 250 km of range in 30 to 45 minutes. A normal grocery run is usually enough time for a meaningful charge.

3. 3

   Move your car if you need more time

   If you need a longer session, move your car to a regular parking spot after the time limit and start a new session if the charger is free when you return.

4. 4

   Use REWE chargers for top-ups, not full charges

   Supermarket chargers work best for adding range while you shop, not for charging from 10% to 100%. If you need a full charge, plan for a dedicated fast charging station.

Poor mobile signal in underground or garage parking

Some REWE stores have chargers in basement or covered parking areas where mobile signal is weak. This can prevent the app from starting a session or processing contactless payments.

Symptoms

• App shows 'No connection' or spins without loading
• Contactless payment times out during processing
• You cannot scan the QR code on the charger because the page will not load
• Session starts but the app loses connection and cannot show charging status

How to Fix It

1. 1

   Connect to REWE store WiFi if available

   Many REWE stores offer free WiFi that may reach the parking area. Check for a REWE network in your phone's WiFi settings.

2. 2

   Walk closer to the garage entrance to start the session

   If you need the app to start the session, walk toward the exit where signal is stronger, start the session remotely, then return to your car.

3. 3

   Use contactless payment instead of the app

   Contactless card payments are processed through the charger's built-in connection, not your phone. If the card reader works, you do not need mobile signal.

4. 4

   Pre-load the app before entering the garage

   Open the app and navigate to the station page while you still have signal. Some apps cache enough data to start a session even with intermittent connectivity.

Charger unavailable outside store hours

You arrive at a REWE charger outside store opening hours and the charger is inaccessible or powered down. Some locations gate their parking areas or shut down chargers when the store closes.

Symptoms

• Parking area gate is locked and you cannot reach the charger
• Charger screen is dark and does not respond
• App shows the charger as available but the physical location is closed
• Barrier arm blocks entry to the parking lot after closing time

How to Fix It

1. 1

   Check store hours before planning a charge

   REWE stores in Germany typically close between 20:00 and 22:00 on weekdays and earlier on Saturdays. Most are closed on Sundays. If the charger is behind a gate, you cannot access it outside these hours.

2. 2

   Verify 24/7 access in the app

   Some REWE charging locations offer 24/7 access even when the store is closed. Check the station details in the app. If it does not mention 24-hour access, assume it follows store hours.

3. 3

   Leave the parking area before the store closes

   If you are charging and the store is about to close, make sure you can exit the parking area. Some locations lock the barrier after closing, which could trap your car overnight.

4. 4

   Find an alternative nearby charger

   Use a multi-network app like Chargemap or the EVcourse charger finder to locate a 24/7 charger nearby. Dedicated charging stations along main roads usually operate around the clock.
