BYD Dolphin Charging at Ionity

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.

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.
