BYD Dolphin Charging at REWE Charging

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.

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.
