Why Your Charging Speed May Differ

The BYD ATTO 3 supports up to 89 kW DC charging. Ionity chargers deliver up to 350 kW. Your car's maximum intake is the limiting factor here, capping speed at 89 kW even on a faster charger.

  • Charging slows down above 80% state of charge on most EVs, including the BYD ATTO 3.
  • Cold weather reduces charging speed. Preconditioning may not be available on all BYD ATTO 3 variants.
  • If multiple cars share the same Ionity station, power may be split between stalls.

BYD ATTO 3 Charging Problems

BYD ATTO 3 Charger Won't Start? Fix It Step by Step

Your BYD ATTO 3 is plugged in but charging has not started. The charger might be blinking, showing an error, or completely unresponsive. This happens to every EV driver eventually. Walk through these steps to figure out whether the problem is the charger, the car, or something in between.

Symptoms

  • Charger display shows an error code after plugging in
  • CCS2 connector is inserted but the ATTO 3 does not respond
  • Charging port indicator light stays off or flashes a warning color
  • Charger screen says 'waiting for vehicle' indefinitely
  • Type 2 AC cable locks in but no power flows to the car

What to Do

  1. 1

    Check the charger screen for instructions

    Read any error messages or prompts on the charger display. It will tell you if authentication is needed, if there is a fault, or if it is waiting for the vehicle to respond.

  2. 2

    Remove and reinsert the connector

    Pull the CCS2 or Type 2 connector out completely, wait 10-15 seconds, and push it back in firmly until you hear the locking click.

  3. 3

    Authenticate with the charger

    Tap your RFID card, open the network's app to start the session, or try contactless payment. If one method fails, try another.

  4. 4

    Check the charge port for obstructions

    Look inside the ATTO 3's charge port for debris, dirt, water, or ice. Clean it gently if needed. Make sure the flap is fully open and not interfering with the connector.

  5. 5

    Lock and unlock the car

    Use the BYD app or key to lock and then unlock the ATTO 3. This can reset the charge port locking mechanism and communication system.

  6. 6

    Try a different charger

    If nothing works, try another stall or station. If another car can charge at the same stall, the issue may be specific to your ATTO 3 and worth a service visit.

BYD ATTO 3 Charging Payment Failed? Quick Fixes

You have your BYD ATTO 3 plugged in and ready, but the payment will not go through. Card rejected, app error, or you simply cannot figure out how to pay at this charger. Payment problems prevent more charging sessions than most people realize. Here is how to solve it.

Symptoms

  • RFID card tap gets no response from the charger
  • Charging app shows payment declined or error
  • Contactless bank card rejected at the charger terminal
  • Charger prompts for payment but nothing you try works
  • Session starts then terminates within seconds due to billing failure

What to Do

  1. 1

    Check accepted payment methods on the charger

    Look for payment logos, QR codes, and instructions on the charger unit. This tells you which RFID cards, apps, or bank card types work here.

  2. 2

    Download and use the network's app

    Scan the QR code or search for the network's app. Create an account, add your card, and start the session through the app. This often works when RFID fails.

  3. 3

    Try a different payment method

    Switch between RFID card, app payment, and contactless bank card. If you have a roaming provider, try that. Having multiple options greatly increases your chances.

  4. 4

    Check for bank holds or declines

    Open your banking app to see if a pre-authorization was attempted and declined. Contact your bank if needed, or try a different card with sufficient available balance.

  5. 5

    Try another stall at the station

    If the card reader is broken on one stall, the next one might work fine. Try the adjacent stall before leaving.

  6. 6

    Find a nearby alternative station

    Use your charging app to find another station nearby where your payment methods are known to work. Filter by network if possible.

BYD ATTO 3 Charging Slowly? LFP Cold Tips Inside

Your BYD ATTO 3 is charging much slower than the 89kW you expected. The ATTO 3 uses an LFP battery, which is great for longevity and safe to charge to 100% daily, but LFP is significantly more sensitive to cold temperatures than NMC chemistry. Without preconditioning, cold weather hits especially hard. Here is what is going on and what you can do.

Symptoms

  • DC charging power well below 89kW on the charger display
  • Extremely slow charging in cold weather, sometimes under 20kW
  • AC charging not reaching 11kW
  • Charging speed drops sharply above 60-70% SOC
  • First charge of the day in winter is dramatically slower than summer

What to Do

  1. 1

    Check the outside temperature

    If it is below 10C, your LFP battery is likely too cold for fast charging. Below 0C, expect significantly reduced speeds. This is the most common cause of slow charging on the ATTO 3.

  2. 2

    Drive longer before charging in cold weather

    Since the ATTO 3 has no preconditioning, drive for at least 30-45 minutes, ideally on a highway, before stopping at a DC charger. This warms the LFP battery through use.

  3. 3

    Check the charger's rated power

    Verify the charger can deliver at least 89kW. A 50kW charger limits your speed regardless of battery temperature. Look for chargers rated 100kW or above.

  4. 4

    Arrive at a lower SOC

    The ATTO 3 charges fastest between 10-50% SOC. On road trips, plan to arrive at each charger between 10-20% for the best speed.

  5. 5

    Choose a stall without power sharing

    Pick a stall where the adjacent one is empty to avoid power sharing. Some stations label which stalls share power output.

  6. 6

    For AC, use a 3-phase Type 2 connection

    The ATTO 3 supports 11kW AC charging. Ensure your cable and charger are both 3-phase capable. A single-phase connection limits you to about 3.6kW.

Common Ionity Issues

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.

Ionity App Tips

  • Download the Ionity app before your trip. You need an account to start sessions at stations where contactless payment is not available or not working.
  • Enable push notifications in the Ionity app. You will get alerts when your session ends or if charging stops unexpectedly.
  • Use the Ionity app's filter to show only stations along your route. The app integrates with Apple Maps and Google Maps for navigation.
  • Check real-time stall availability in the app before driving to a station. Tap the station pin to see which individual chargers are free, occupied, or faulted.
  • If you have an Ionity subscription, always start sessions through the app to make sure you get the subscription rate. Contactless payment defaults to the ad-hoc price.

Payment Tips

  • Ionity offers subscription plans that significantly reduce the per-kWh price compared to the ad-hoc rate. Check the Ionity app for current plans and pricing. Worth it if you use Ionity twice a month or more.
  • Contactless payment pre-authorizes up to 100 EUR on your card. The actual charge appears later and the hold is released within a few days.
  • Check if your car brand offers an Ionity deal. Hyundai, Kia, BMW, Mercedes, VW Group brands, and Ford all have discounted Ionity access through their own charging apps.
  • Ad-hoc (pay-as-you-go) rates at Ionity are among the highest in Europe. If you do not want a subscription, roaming through Shell Recharge or Chargemap is usually cheaper than paying ad-hoc.
  • Ionity invoices are available in the app under your account. You can download PDF receipts for expense reports.
