Citroen e-C4 Charging at Ionity

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.

Session won't start after contactless payment

You tap your card, the reader beeps, but the charger never begins delivering power. This is one of the most reported issues at Ionity stations.

Symptoms

• Contactless reader shows a green light but nothing happens
• Screen says 'Initializing' for more than 60 seconds
• Card is charged a pre-authorization hold but no energy is delivered
• Error message appears after the tap but disappears too quickly to read

How to Fix It

1. 1

   Unplug the cable and wait 10 seconds

   This resets the charger's session state. Plug the cable back in firmly until you hear the locking click.

2. 2

   Try a different payment method

   Open the Ionity app and start the session from there instead. If you have an Ionity subscription, use the app. App-initiated sessions bypass the contactless reader entirely.

3. 3

   Check your card's contactless limit

   Some banks block contactless transactions above a certain amount. Ionity may pre-authorize up to 100 EUR. If your bank flags this, the session fails silently.

4. 4

   Move to another stall at the same station

   Individual charger units can have faulty card readers while the rest of the station works fine. Try the next available stall.

5. 5

   Check for a pending hold on your bank statement

   If a hold was placed but no session started, it typically releases within 3 to 7 business days. You will not be charged for energy you did not receive.

Plug & Charge pairing fails

Your vehicle supports Plug & Charge (ISO 15118) but the Ionity station does not recognize it. The charger asks for payment instead of starting automatically.

Symptoms

• Charger prompts for app or card payment instead of starting automatically
• Screen shows 'Vehicle not recognized'
• Plug & Charge worked at this station before but stopped working
• Pairing completed in the Ionity app but the station still asks for payment

How to Fix It

1. 1

   Verify Plug & Charge is enabled in your vehicle settings

   Some vehicles (like Porsche Taycan, BMW iX, Mercedes EQS) have a toggle in the infotainment system. If it was turned off during a software update, the charger cannot identify your car.

2. 2

   Re-pair your vehicle in the Ionity app

   Go to the Ionity app, navigate to Plug & Charge settings, remove the existing pairing, and set it up again. This refreshes the digital certificate.

3. 3

   Check that your Ionity subscription is active

   Plug & Charge on Ionity requires an active subscription. If your subscription lapsed, the auto-start will fail even if the pairing is intact.

4. 4

   Try unplugging and re-plugging slowly

   The ISO 15118 handshake happens in the first few seconds. If you plug in too quickly or the connector is not fully seated, the handshake times out and the charger falls back to manual payment.

5. 5

   Start the session via the app as a fallback

   Plug & Charge issues are often caused by backend certificate mismatches. You can still charge at Ionity subscription rates by starting the session through the app while the issue is resolved.

Charger screen frozen or unresponsive

The charger display is stuck on a loading screen, shows garbled text, or does not respond to touch. The hardware may still work even if the screen does not.

Symptoms

• Screen shows a logo or loading animation that never progresses
• Touch inputs on the screen do nothing
• Screen is completely black but the charger lights are on
• Screen shows an error code that does not clear

How to Fix It

1. 1

   Try plugging in and starting via the app

   The screen and the charging hardware are separate systems. Many Ionity chargers will still deliver power even with a frozen display if you initiate the session through the Ionity app.

2. 2

   Unplug completely and wait 30 seconds

   Sometimes unplugging triggers a soft reset of the charger unit. Wait, then try again.

3. 3

   Try a different stall

   Ionity stations typically have multiple charger units. A frozen screen on one unit does not affect the others.

4. 4

   Report the charger in the Ionity app

   Open the Ionity app, find the station, and report the specific charger as out of order. This helps Ionity dispatch maintenance faster.

App shows station available but charger is faulted

The Ionity app shows green (available) status for a station, but when you arrive, the chargers display errors or are physically out of service.

Symptoms

• App shows 'Available' but charger displays 'Out of Order'
• All stalls at the station are faulted despite the app showing availability
• Charger has a maintenance sticker or barrier but the app has not been updated
• You drove to a station specifically because the app said it was free

How to Fix It

1. 1

   Refresh the station status in the app

   Pull down to refresh the station view. Status updates can lag by several minutes, especially after a charger was recently reported or rebooted.

2. 2

   Check individual charger status, not just the station

   Tap into the station details in the Ionity app. Even if some stalls show faulted, others at the same station may still work.

3. 3

   Try plugging in anyway

   Occasionally a charger shows a stale error on its screen from a previous session but works fine for the next user. Plug in and attempt to start via the app.

4. 4

   Plan a backup station

   Before driving to an Ionity station, check if there is an alternative station within 10 to 15 minutes. Ionity stations along highways sometimes have another Ionity or competitor station at the next exit.

5. 5

   Report the discrepancy

   Use the 'Report a problem' option in the Ionity app. Accurate reports help Ionity fix status sync issues and prioritize maintenance.

Unexpectedly high ad-hoc price

You charged without an Ionity subscription subscription and the per-kWh price is significantly higher than you expected. Ionity's ad-hoc rate is one of the most expensive in Europe.

Symptoms

• Invoice shows 0.75 EUR/kWh or higher
• Total cost for a short session is much higher than expected
• Price displayed on the charger screen was not noticed before starting
• You assumed the price would be similar to home charging or other networks

How to Fix It

1. 1

   Check if Ionity subscription would save you money

   Ionity offers subscription plans that reduce the per-kWh price significantly. Check the Ionity app for current plans and rates. If you charge at Ionity more than once or twice a month, a subscription usually pays for itself.

2. 2

   Check your vehicle manufacturer's charging plan

   Many EV manufacturers (Hyundai, Kia, BMW, Mercedes, Volkswagen Group, Ford) offer bundled Ionity pricing through their own apps. You may already have access to a discounted rate through your car brand.

3. 3

   Look at the charger screen before starting next time

   Ionity displays the per-kWh price on the charger screen before the session starts. The ad-hoc price is always shown.

4. 4

   Consider roaming providers for occasional use

   If you do not want a subscription, some roaming apps (like Shell Recharge, Chargemap, or Maingau) offer lower Ionity rates than the ad-hoc price.

Charging speed much lower than 350 kW

The station advertises 350 kW but your vehicle is charging at a fraction of that speed. This can be normal or it can indicate a problem.

Symptoms

• Dashboard shows 50 to 100 kW at a 350 kW charger
• Charging started fast but dropped sharply after a few minutes
• Other vehicles at the same station seem to charge faster
• Speed is lower than what you normally get at Ionity

How to Fix It

1. 1

   Check your battery level

   Charging speed drops significantly above 60 to 80% state of charge on most vehicles. This is normal battery behavior, not an Ionity issue. For the fastest stop, charge from 10 to 80% and move on.

2. 2

   Check the battery temperature

   Cold batteries charge slowly. If your vehicle supports battery preconditioning, set the Ionity station as your navigation destination. The car will warm the battery on the way there.

3. 3

   Verify your vehicle's max DC charging speed

   Not all EVs can accept 350 kW. Many popular models top out at 100 to 150 kW. The charger delivers only what the vehicle requests.

4. 4

   Try a different stall

   Individual charger units can occasionally have hardware limitations or faults that reduce output. Moving to another stall at the same station can sometimes restore full speed.

5. 5

   Check for power sharing

   Some Ionity stations share power between adjacent stalls. If the neighboring stall is also in use, both vehicles may receive reduced power. Try a stall that is not next to another active session.
