Why Your Charging Speed May Differ

The BYD Dolphin supports up to 88 kW DC charging. Le Plein chargers deliver up to 200 kW. Your car's maximum intake is the limiting factor here, capping speed at 88 kW even on a faster charger.

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

BYD Dolphin Charging Problems

BYD Dolphin Charger Won't Start? Quick Fix Guide

Your BYD Dolphin is plugged in but charging is not starting. The charger might show an error, the car might not respond, or you are stuck on the authentication screen. Most failed charging starts have a simple explanation. Here is how to work through it step by step.

Symptoms

  • Charger display shows error after plugging in the CCS2 connector
  • Dolphin charge port light stays off or shows a warning color
  • Car dashboard indicates no charging activity
  • Charger screen stays on authentication or welcome screen
  • Type 2 cable locks but no power flows

What to Do

  1. 1

    Read the charger display

    Check for error messages, prompts, or status indicators. If it asks for authentication, that is your next step. If it shows a fault, the charger is the problem.

  2. 2

    Unplug and replug the connector

    Remove the CCS2 or Type 2 connector completely, wait 10-15 seconds, and push it back in firmly. Listen for the locking click.

  3. 3

    Authenticate with the charger

    Tap your RFID card, start the session in the app, or use contactless payment. Try authenticating both before and after plugging in.

  4. 4

    Clean the charge port

    Inspect the Dolphin's charge port for debris, ice, or moisture. Wipe it clean with a dry cloth. In winter, gently remove any ice buildup.

  5. 5

    Check for charging schedules

    In the Dolphin's settings, look for any scheduled or delayed charging options. Disable them to allow immediate charging.

  6. 6

    Try a different stall or station

    If the charger is at fault, move to another stall or find an alternative station using your charging app.

BYD Dolphin Charging Payment Failed? Fix It Here

Your BYD Dolphin is plugged in and ready, but the payment is not going through. Whether it is an RFID card, an app, or contactless, payment problems are one of the most common reasons a charging session fails. Here is how to get it working.

Symptoms

  • RFID card does not register when tapped on the charger
  • Network app shows payment error or declined transaction
  • Contactless bank card rejected at the terminal
  • Charger asks for authentication but does not accept anything
  • Session starts then immediately stops due to payment failure

What to Do

  1. 1

    Check accepted payment methods

    Look at the charger for payment logos and instructions. Determine whether it accepts RFID, app payments, contactless cards, or specific network cards only.

  2. 2

    Try the network's app

    Scan the QR code or find the app in your phone's app store. Create an account, add payment, and start the session through the app.

  3. 3

    Switch payment methods

    Try a different card, a roaming provider (Plugsurfing, Shell Recharge, Chargemap), or a different app. Having multiple options increases your success rate.

  4. 4

    Check your bank for declines

    Open your banking app to see if a pre-authorization was blocked. Approve it or try a different card with a higher available balance.

  5. 5

    Try another stall

    The card reader on one stall may be faulty. Move to the next stall and try again.

  6. 6

    Find a nearby alternative

    If nothing works, search for a different station where your payment methods are confirmed to work.

BYD Dolphin Charging Slowly? LFP Cold Weather Tips

Your BYD Dolphin is not charging as fast as you expected. With a maximum DC speed of 88kW and an LFP battery, the Dolphin has some specific quirks. LFP chemistry is safe to charge to 100% daily, but it is more sensitive to cold temperatures than NMC. Without preconditioning, winter performance takes a real hit. Here is what affects your speed.

Symptoms

  • DC charging well below 88kW even on a capable charger
  • Extremely slow charging in cold weather, sometimes under 20kW
  • AC charging stuck below 11kW
  • Charging slows significantly above 60% SOC
  • First charge of the day in winter is much slower than subsequent ones

What to Do

  1. 1

    Check the outside temperature

    If it is below 10C, cold is very likely the primary issue. LFP batteries lose charging speed faster than NMC in cold. Below 0C, expect dramatically slower charging.

  2. 2

    Drive longer before fast charging in cold weather

    Without preconditioning, highway driving for 30-45 minutes before a DC stop is the best way to warm the Dolphin's LFP battery. A short city drive is not enough.

  3. 3

    Check the charger's power rating

    Verify the charger is rated at 100kW or higher to access the Dolphin's full 88kW capability. A 50kW charger is the max you will get regardless of conditions.

  4. 4

    Charge at a lower SOC

    Arrive between 10-20% for the fastest charging speed. Avoid stopping when you are already at 60-70%, as the taper means much slower speeds.

  5. 5

    Pick a stall without power sharing

    Choose a charger where no adjacent car is charging. Power sharing can cut your speed in half.

  6. 6

    For AC, ensure 3-phase connection

    Use a 3-phase Type 2 cable on an 11kW charger to reach the Dolphin's full AC speed. Single-phase limits you to about 3.6kW.

Common Le Plein Issues

App and charger interface only in French

The Le Plein app and the charger screen interface are primarily in French. If you do not read French, navigating menus and understanding error messages takes extra effort.

Symptoms

  • The app menus, buttons, and instructions are entirely in French
  • The charger screen shows an error message you cannot read
  • You cannot find the 'start session' button because the labels are in French
  • Support articles and FAQ in the app are in French only

How to Fix It

  1. 1

    Learn the key French charging terms

    A few words go a long way. 'Démarrer' means start, 'Arrêter' means stop, 'Brancher' means plug in, 'En charge' means charging, 'Disponible' means available, 'Hors service' means out of order. With these, you can navigate most screens.

  2. 2

    Use your phone's translation feature on the charger screen

    Most smartphones can translate text from a photo. Point your camera at the charger screen and use Google Translate, Apple Translate, or a similar app to read the message. This works well for error messages you do not recognize.

  3. 3

    Set up the session flow before you arrive

    Open the Le Plein app at home and familiarize yourself with the session flow: find station, select charger, start session. Once you know where the buttons are, the French labels matter less.

  4. 4

    Use your phone's built-in app translation if available

    On Android, you can translate app interfaces using the system translation feature. On iOS, you can take a screenshot and translate it. This helps with menus and settings you need to navigate once.

RFID card ordering process through the app

Le Plein RFID cards can only be ordered through the app. There is no option to buy one at a station or from a retail location. The ordering and activation process has a few steps that can trip people up.

Symptoms

  • You want an RFID card but cannot find where to order it
  • You ordered a card but it has not arrived after the expected delivery time
  • Your RFID card arrived but does not work at the charger
  • The app says your card is active but the charger does not recognize it

How to Fix It

  1. 1

    Order the card through the Le Plein app account section

    Open the Le Plein app, go to your account or profile settings, and look for an RFID card or badge option. Follow the ordering flow, which will ask for your delivery address. Delivery takes several business days within France.

  2. 2

    Activate the card in the app after it arrives

    When the card arrives, you may need to activate it in the Le Plein app by entering the card number or scanning it. Check the instructions that came with the card. An unactivated card will not start a session.

  3. 3

    Make sure your payment method is valid

    The RFID card charges sessions to the payment method saved in your Le Plein account. If your saved card has expired or been declined, the RFID card will not work even though it is activated. Update your payment details in the app.

  4. 4

    Use the app to start sessions while waiting for the RFID card

    You do not need the physical RFID card to charge. The Le Plein app can start sessions directly. Use the app until your card arrives and is activated.

Station coverage concentrated in certain French regions

Le Plein's network does not cover all of France equally. Some regions have good coverage while others have very few or no stations. This can be a problem on longer trips.

Symptoms

  • The app shows no Le Plein stations along a section of your route
  • Stations are clustered around certain cities but absent in rural areas between them
  • You planned a trip assuming Le Plein coverage and found a gap
  • The nearest Le Plein station is far from your destination

How to Fix It

  1. 1

    Check Le Plein coverage along your entire route before departing

    Open the Le Plein app and trace your route on the map. Look for gaps where there are no stations for long stretches. Identify these gaps before you leave, not when your battery is low.

  2. 2

    Install backup charging apps for other French networks

    France has several other charging networks, including Ionity, TotalEnergies, Fastned, and local operators. Having apps for two or three networks ensures you always have a fallback when Le Plein coverage runs out.

  3. 3

    Use a roaming RFID card for multi-network access

    A roaming card from Chargemap or another aggregator can access chargers from multiple French networks. This is especially useful in areas where Le Plein has no presence.

  4. 4

    Plan with a multi-network route planner

    A Better Routeplanner (ABRP) or Chargemap show stations from all networks. Enter your vehicle and destination to get charging stops that work regardless of the operator.

Charger screen errors you cannot decipher

When something goes wrong at a Le Plein charger, the error message on the screen is in French. If you do not understand the message, you cannot tell whether to retry or move on.

Symptoms

  • The screen shows an error code or message in French after you plug in
  • The charger stopped mid-session and the screen displays a French message
  • You see 'Hors service' or 'Erreur' but do not know the specific problem
  • The screen shows instructions you cannot follow

How to Fix It

  1. 1

    Photo-translate the error message

    Take a photo of the screen and use Google Translate's camera feature or Apple Translate to read it. This gives you the specific error, not just a guess.

  2. 2

    Know the most common French charger errors

    'Hors service' means out of order, do not wait. 'Erreur de communication' means a communication error between charger and vehicle, try replugging. 'Session en cours' means a session is already active, possibly from a previous user who did not end it. 'Veuillez patienter' means please wait.

  3. 3

    Try unplugging and reconnecting

    Many charger errors clear themselves when you unplug, wait 30 seconds, and plug in again. This resets the communication between your vehicle and the charger.

  4. 4

    End any stuck session in the Le Plein app

    If the charger thinks a session is still active from a previous user, you may not be able to start a new one. Check the app to see if there is an active session on that charger. Sometimes you need to wait for it to time out.

  5. 5

    Move to another charger if the error persists

    If the same error appears after two or three attempts, the charger likely has a hardware or software issue. Try another charger at the same station, or drive to the next Le Plein or alternative station.

Support phone line in French only

Le Plein's support phone line is staffed by French-speaking agents. If you need help at a station and do not speak French, communication can be difficult.

Symptoms

  • You called support and the agent speaks only French
  • The automated phone menu is in French with no language option
  • You cannot explain your problem over the phone
  • You need urgent help at a station but cannot communicate effectively

How to Fix It

  1. 1

    Try the app's support or help section first

    Written support through the app (email, contact form, or chat) gives you time to use a translation tool. Type your question in English, translate it to French, and paste it. This is often more effective than a phone call.

  2. 2

    Prepare a few key phrases in advance

    If you may need to call, have these ready: 'La borne ne fonctionne pas' (the charger is not working), 'Le câble est bloqué' (the cable is stuck), 'J'ai besoin d'aide' (I need help), and the station number or location name.

  3. 3

    Use a real-time translation app during the call

    Google Translate's conversation mode can translate speech in both directions. It is not perfect, but it helps bridge the gap. Open it before you call.

  4. 4

    Ask a nearby person for help if available

    If you are at a station and someone nearby speaks both French and your language, asking for a quick translation assist is perfectly reasonable. Most people are happy to help.

Le Plein App Tips

  • Familiarize yourself with the Le Plein app at home before your first charging session. Walk through the menus so you know where to find stations, start a session, and check your history.
  • The app shows real-time charger availability. 'Disponible' means available. 'Occupé' means occupied. 'Hors service' means out of order.
  • Screenshot or save the station details (address, charger ID) before you start driving. If you lose signal at the station, you still have the information you need.
  • Check the app for your charging history and receipts. Each session shows energy delivered, duration, and cost.

Payment Tips

  • The Le Plein app is the fastest way to pay. You can start a session in the app without waiting for an RFID card to arrive.
  • RFID cards must be ordered through the app and shipped to a French address. If you are visiting France temporarily, use the app for payment instead.
  • Make sure your saved payment card supports international transactions if you are from outside France. Some banks block foreign pre-authorization charges unless you notify them.
  • Le Plein pricing is per kWh. The rate is displayed in the app before you start. Check it, as rates can change.
