Citroen e-C4 Charging at REWE Charging

Citroen e-C4 Charger Won't Start? Step-by-Step Fix

Your Citroen e-C4 is connected to the charger but nothing is happening. No power, no progress, and maybe an error flashing on the charger screen. This is a common problem at public charging stations and it usually has a straightforward fix.

Symptoms

• CCS2 connector inserted but no charging session begins
• Charger screen shows an error code or connection failure
• The e-C4's charge port indicator does not light up or blinks red
• Charger starts to initialize but disconnects within seconds
• Type 2 connector locks in at an AC station but no power flows

What to Do

1. 1

   Complete the authentication step

   Tap your RFID card, start a session in the charging app, or use contactless payment. Follow the charger's on-screen instructions. Some networks require authentication before plugging in, others after.

2. 2

   Unplug and firmly reseat the connector

   Pull the CCS2 or Type 2 connector out completely and reinsert it straight into the charge port with a firm push until it clicks. Keep the cable aligned and support its weight.

3. 3

   Disable scheduled charging on the touchscreen

   Open the charging settings on the e-C4's central touchscreen. Turn off any scheduled or deferred charging mode so the car accepts power immediately.

4. 4

   Clean the charge port

   Check the charge port on the left rear for dirt, salt, or ice. Wipe the contacts with a dry cloth. In freezing weather, gently clear any ice from the port opening and door.

5. 5

   Lock and unlock the vehicle to reset

   Use the key fob or the MyCitroen app to lock the car, wait 10 seconds, then unlock it. This resets the charge port controller. Try plugging in again.

6. 6

   Try a different charger

   Move to another stall at the same station or find a nearby alternative. Some charger faults affect only one unit while others at the same site work fine.

Citroen e-C4: Charger Payment Failed? Quick Fixes

Your Citroen e-C4 is plugged in, but the payment is not going through. RFID rejected, app error, or bank card declined. This is entirely a charger and payment issue, not a car problem. Here is how to sort it out and start charging.

Symptoms

• RFID card rejected with an error beep or message
• Charging network app shows a payment error or session failure
• Contactless bank card declined at the charger terminal
• Pre-authorization hold appears but no charging session starts
• Charger starts briefly then stops with a billing error

What to Do

1. 1

   Check accepted payment methods on the charger

   Look at the charger's display and body for logos showing which RFID networks, apps, or card payment options are accepted.

2. 2

   Try a different payment method

   Switch from RFID to the network app, or from the app to a contactless bank card. Always carry at least two options.

3. 3

   Check your bank card balance

   Open your banking app and confirm you have enough available balance for a pre-authorization hold. Some chargers hold up to 80 EUR upfront.

4. 4

   Update or restart the charging app

   Check for updates, close and reopen the app, and look for any stuck open sessions. Log out and back in if the problem persists.

5. 5

   Use the charger's built-in card reader

   Look for a contactless card reader on the charger. More European stations now offer direct bank card payment, which bypasses RFID and app issues.

6. 6

   Call the support number on the charger

   Every public charger displays a support number. The operator can sometimes start a session remotely or diagnose the payment issue from their end.

Citroen e-C4 Charging Too Slow? How to Fix It Now

Your Citroen e-C4 can charge at up to 100 kW on a DC fast charger, but you might be getting far less. The 50.8 kWh NMC battery sits on the Stellantis e-CMP platform, and its charging behavior has some known limitations. Here is what holds back your speed and how to work around it.

Symptoms

• DC charging power stays well below 100 kW even at a high-power station
• Charging speed drops steeply before reaching 50% state of charge
• AC charging at home maxes out at 3.6 kW instead of 11 kW
• The touchscreen shows an estimated time much longer than expected
• Cold weather charging sessions take nearly twice as long as summer sessions

What to Do

1. 1

   Drive at highway speed for 15-20 minutes before fast charging

   Since the e-C4 has no battery preconditioning, active driving is the best way to warm the battery. Highway driving before your charging stop makes a meaningful difference in cold weather charging speeds.

2. 2

   Arrive at the charger between 10% and 20%

   The e-C4 charges fastest at low state of charge. Plan your stop so you arrive around 10-15% to take advantage of peak speeds. The difference between 10% and 50% arrival can be 30-40 kW.

3. 3

   Pick a charger stall that is not sharing power

   Check if two CCS2 cables come from one cabinet. Choose the stall where the other connector is free. This ensures you get the full power output from the charger.

4. 4

   Verify your home AC setup

   Check the power reading on the e-C4's touchscreen during a home AC charge. If it shows about 3.6 kW, you are on single-phase power. A three-phase upgrade unlocks the full 11 kW.

5. 5

   Monitor the charging screen

   During DC charging, watch the current power on the touchscreen. If it starts low, the battery may be warming up. Give it 5-10 minutes. Power should gradually increase as the battery temperature rises.

6. 6

   Stop DC charging at 80% on road trips

   The last 20% takes disproportionately long. On longer drives, unplug at 80% and drive to the next charging stop. You will save significant time overall.

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.
