Mercedes-Benz EQB Charging at Iberdrola

Mercedes-Benz EQB Charger Won't Start: Quick Fixes

You have connected your Mercedes-Benz EQB to a public charger, but the session will not start. MBUX shows nothing, the charger sits idle, and you are wondering what is wrong. This is one of the most common complaints at public chargers, and it is usually fixable on the spot.

Symptoms

• The charger screen stays on 'waiting' or 'connect vehicle' after plugging in
• MBUX does not show any charging activity
• The EQB's charge port LED does not illuminate
• The charger returns an error code after you connect
• The CCS2 connector does not click into place

What to Do

1. 1

   Unlock the EQB and open the charge port

   Ensure the car is unlocked. Press the charge port flap to open it. On some EQB models, you can also open it through the Mercedes me app.

2. 2

   Insert the connector firmly

   Push the CCS2 or Type 2 connector straight into the port until it clicks. The charge port is on the right side of the EQB. A locked connector triggers the charging protocol.

3. 3

   Authenticate at the charger

   Tap your RFID card on the charger reader, start the session in the network app, or tap your bank card on the contactless terminal. The charger needs authorization before sending power.

4. 4

   Disable scheduled charging in MBUX

   In MBUX, navigate to EV settings, then charging. If a schedule is set, switch to immediate charging so the EQB does not wait for a timer.

5. 5

   Disconnect and retry

   Unplug the cable, wait 15 seconds, and reconnect. This forces a fresh handshake between the EQB and the charger.

6. 6

   Try another charger

   If the charger remains unresponsive, it is likely out of service. Move to a different stall or station and report the faulty unit through the network's app.

Mercedes-Benz EQB Charging Payment Failed: Fix Now

You have connected your Mercedes-Benz EQB to a charger, but the payment will not go through. RFID not recognized, app error, or bank card declined. This is a charger-side issue, not an EQB problem, but it still blocks your session. Here is how to get charging.

Symptoms

• The charger displays 'authentication failed' or 'payment declined'
• Your RFID card tap produces no response
• The charging app returns an error when starting a session
• Contactless bank card payment is declined
• The charger asks for payment but no method works

What to Do

1. 1

   Try an alternative payment method

   Switch from RFID to the charging app, or from the app to a contactless bank card. Having multiple options ensures one failure does not strand you.

2. 2

   Check your account status

   Open the charging app and verify your payment method, balance, and subscription status. Fix any issues before retrying.

3. 3

   Verify the charger supports your network

   Look for provider logos on the charger. If yours is not there, you need ad-hoc payment via QR code or a different provider.

4. 4

   Scan the QR code for ad-hoc payment

   Most European chargers have a QR code that opens a browser-based payment page. Pay with any bank card, no app needed.

5. 5

   Cancel and restart the session

   If payment seemed to go through but charging did not start, cancel in the app and try again with a fresh authorization.

6. 6

   Contact the network's support

   The charger should display a phone number. The operator can sometimes authorize sessions remotely or troubleshoot payment issues.

Mercedes-Benz EQB 350+ Charging Slow: How to Fix It

Your Mercedes-Benz EQB 350+ supports up to 102kW DC fast charging, which is moderate for its class. If the MBUX display is showing far less than that, every charging stop takes longer than it should. Here is what affects the EQB's charging speed and how to improve it.

Symptoms

• DC charging power shown on MBUX is well below 102kW
• Charging the 70.5kWh battery takes significantly longer than expected
• Speed drops noticeably above 70% state of charge
• AC charging is stuck below 11kW at a faster station
• MBUX displays a battery temperature warning or conditioning indicator

What to Do

1. 1

   Check charging power in MBUX

   Open the charging status screen on MBUX. It displays current kW, battery temperature, and estimated completion time. This tells you whether the car or charger is limiting speed.

2. 2

   Precondition the battery before arriving

   Enter the charging station as a destination in MBUX navigation. The EQB will precondition the battery to optimal temperature while you drive. This is the single most effective step in cold weather.

3. 3

   Find a charger rated at 100kW or more

   Use the Mercedes me app or a charger map to locate high-power stations. Ionity, Fastned, and some Shell Recharge stations offer 100kW+ chargers.

4. 4

   Avoid power-sharing stalls

   Choose a charger pair where the adjacent stall is empty. This gives the EQB the full output of the charger.

5. 5

   Charge between 10% and 80%

   Plan stops to arrive between 10% and 15% and leave at 80%. This keeps you in the EQB's fastest charging window.

6. 6

   Check for software updates

   Mercedes releases over-the-air updates that can improve charging behavior. Check MBUX under Settings for available updates.

App defaults to Spanish

The Iberdrola app opens in Spanish regardless of your phone's language setting. Finding the language switch can be confusing if you do not read Spanish.

Symptoms

• All app text is in Spanish after installation
• Language setting is not obvious in the menus
• Error messages and charger instructions appear only in Spanish
• Switching your phone's language does not change the app

How to Fix It

1. 1

   Open the app settings and look for 'Idioma'

   'Idioma' means 'Language' in Spanish. It is usually under the profile or settings menu (gear icon). Tap it and select English or your preferred language.

2. 2

   Check the profile or account section

   Some versions of the Iberdrola app place the language selector inside the user profile rather than in general settings. Look for your name or account icon at the top of the screen.

3. 3

   Update the app to the latest version

   Iberdrola has been improving multi-language support. Older versions may not have your language available. Update from the App Store or Google Play.

4. 4

   Use a roaming app as a backup

   If the language barrier is too frustrating, roaming apps like Chargemap, Shell Recharge, or Electropass work at many Iberdrola stations and offer broader language support.

Contactless payment session timeout

After tapping your card on an Iberdrola charger, there is a short window to plug in the cable and start charging. If you take too long, the session times out and you need to tap again.

Symptoms

• You tapped your card but by the time you connected the cable, nothing happened
• Charger screen shows 'Session expired' or returns to the start screen
• You were charged a pre-authorization but no energy was delivered
• The charger seemed ready but then went back to idle

How to Fix It

1. 1

   Plug in the cable first, then tap your card

   At Iberdrola stations, connect the cable to your vehicle before tapping your contactless card. This gives the charger the best chance to start immediately after authentication.

2. 2

   Tap your card again and act quickly

   After the tap, you typically have 60 to 90 seconds to complete the connection. If you missed the window, tap again. The pre-authorization from the first attempt will be released.

3. 3

   Use the Iberdrola app instead

   The app does not have the same time pressure. You can connect the cable, open the app, select the charger, and start at your own pace.

4. 4

   Check your bank statement for ghost charges

   Failed contactless attempts may show a pre-authorization hold. These are not actual charges and typically release within 3 to 7 business days. Contact your bank if they persist.

Confusing signage at gas station locations

Some Iberdrola chargers are located at gas stations (Repsol, Cepsa, or others). The EV charging area may not be clearly separated from the fuel pumps, and signage can be confusing.

Symptoms

• You cannot find the EV chargers at the gas station
• GPS directs you to the fuel pumps instead of the charging area
• Signage points to 'carga' or 'recarga' but the direction is unclear
• The charging spots are behind the gas station building or in an overflow lot

How to Fix It

1. 1

   Look for the charging area separate from the fuel pumps

   EV chargers at gas stations are almost always in a dedicated area away from the fuel pumps. Look for tall charger cabinets (about 2 meters high) rather than fuel dispensers.

2. 2

   Drive past the fuel pump area

   The charging area is often behind the main building, in a side lot, or at the far end of the property. Drive through the station slowly and look for the Iberdrola or charging network signage.

3. 3

   Ask the gas station attendant

   If the station has staff, ask where the electric charging points are. In Spanish, 'Donde estan los cargadores electricos?' gets the point across.

4. 4

   Check the Iberdrola app for station photos

   The station detail page in the Iberdrola app sometimes includes photos or access instructions that help you find the chargers within a larger gas station complex.

Mix of slow and fast chargers at the same station

Some Iberdrola stations have both AC chargers (7 to 22 kW) and DC fast chargers (50 to 350 kW) next to each other. It is easy to plug into a slow charger by mistake if you are not paying attention.

Symptoms

• You expected fast charging but your dashboard shows only 7 or 22 kW
• The charger you plugged into looks smaller than the others at the station
• You used a Type 2 cable instead of a CCS2 connector
• The charging session is going to take hours instead of minutes

How to Fix It

1. 1

   Check the charger label for power output

   Iberdrola chargers display their rated power (e.g., 50 kW, 150 kW, 350 kW) on the unit. Look for this label before plugging in. AC chargers (7 to 22 kW) are typically smaller and have Type 2 sockets.

2. 2

   Use the CCS2 connector for fast charging

   The CCS2 connector is the large combined plug for DC fast charging. If you used the smaller Type 2 plug (round with pins), you are on AC and will charge slowly.

3. 3

   Check the Iberdrola app for charger details

   The app shows each charger unit's power level at a station. Before plugging in, confirm which unit is the high-power DC charger.

4. 4

   Unplug and move to the fast charger

   If you accidentally started an AC session, stop the session in the app, unplug, and move to the DC fast charger. You will not be charged a penalty for a short session.

Power delivery varies by time of day

Some Iberdrola stations deliver noticeably less power during peak grid hours (typically early evening). This is due to grid constraints, not a charger fault.

Symptoms

• Charging speed is significantly lower in the evening than the same station delivered in the morning
• Speed starts high but drops during peak hours even at low battery levels
• Other vehicles at the station also show reduced speeds at the same time
• The charger does not reach its rated power despite your vehicle supporting it

How to Fix It

1. 1

   Check your battery level first

   The most common reason for reduced charging speed is a battery above 60 to 80% state of charge. Your vehicle limits the charging rate at higher battery levels regardless of the charger's capability.

2. 2

   Try charging during off-peak hours

   If your schedule allows, charge during late evening (after 10 PM) or early morning. Grid demand is lower and the station can deliver its full rated power.

3. 3

   Check for power sharing between chargers

   If multiple chargers are in use at the same station, they may share a grid connection. Charging when fewer vehicles are plugged in can improve your speed.

4. 4

   Try a different station nearby

   Not all Iberdrola stations have the same grid connection. A station a few kilometers away may have a better power supply and deliver higher speeds during peak hours.

5. 5

   Accept the reduced speed if you are above 60%

   If your battery is above 60%, the speed reduction is mostly from your vehicle's battery management, not the grid. This is normal and protects your battery's long-term health.
