Mercedes-Benz EQS Charging at K-Lataus

Mercedes-Benz EQS Charger Won't Start a Session

You connected the CCS2 cable to your EQS's right rear charge port, but the Hyperscreen shows no charging activity. No power flowing, no progress. This is frustrating, especially in a flagship sedan where everything should just work. The cause is usually authentication, cable seating, or the charger itself, not the EQS.

Symptoms

• CCS2 connector plugged in but the Hyperscreen shows no charging activity
• Charger screen displays an error or stays idle after authentication attempt
• Plug & Charge does not authenticate automatically at a supported station
• Charge port LED does not illuminate or blinks an error pattern
• Mercedes me app shows the EQS as connected but not charging

What to Do

1. 1

   Remove and firmly reseat the CCS2 connector

   Pull the connector out of the right rear charge port. Check for debris or moisture. Push it back in straight and firm until you hear a click and see the charge port LED respond. The CCS2 connector is heavy, so support it with both hands to ensure proper alignment.

2. 2

   Authenticate manually if Plug & Charge failed

   Open the charging network's app and start the session by scanning the QR code or selecting the charger. If you have an RFID card for this network, tap it on the reader. Do not wait for Plug & Charge if it did not work within 30 seconds.

3. 3

   Disable scheduled charging in MBUX

   On the Hyperscreen, open Settings, then Charging. Turn off any departure time or scheduled charging window. At a public charger, you want charging to start immediately. Re-enable scheduled charging when you are back at your home wallbox.

4. 4

   Lock and unlock the EQS to reset the charge controller

   Use the key or Mercedes me app to lock the car. Wait 15 seconds, then unlock. This resets the charge port locking mechanism and the onboard charging communication module. Reconnect the cable after unlocking.

5. 5

   Try a different connector or charger at the station

   If the station has multiple CCS2 connectors, try a different one. If the entire station seems unresponsive, use MBUX navigation to find another nearby charger. Report the faulty charger through the network's app.

Mercedes-Benz EQS Payment Failed at Charging Station

You are standing next to your EQS at a public charger and payment will not go through. Plug & Charge did not activate, the app shows an error, or your card was declined. Payment failures are one of the most common reasons charging sessions do not start. With the EQS, you have multiple authentication options to try before giving up.

Symptoms

• Plug & Charge does not authenticate when the CCS2 cable is connected
• Contactless card declined at the charger's payment terminal
• Mercedes me Charge or the network's app shows a payment error
• RFID card not recognized by the charger reader
• Session starts but stops immediately with a billing-related error

What to Do

1. 1

   Try Plug & Charge by connecting the cable

   Plug the CCS2 connector into the EQS's right rear charge port. Wait up to 30 seconds for Plug & Charge to authenticate. Check the Hyperscreen for a charging confirmation. If nothing happens after 30 seconds, Plug & Charge is not working at this station.

2. 2

   Use the charging network's app to start the session

   Open the app for the charging network shown on the charger. Scan the QR code or enter the charger ID. Start the session through the app. Verify your payment method in the app is valid and not expired.

3. 3

   Try contactless payment at the charger terminal

   If the charger has a contactless payment terminal, tap your bank card, Apple Pay, or Google Pay. If the first card is declined, try a different one. Some terminals accept only certain card brands.

4. 4

   Verify your Mercedes me Charge account

   Open the Mercedes me app. Go to Charge settings and check that Plug & Charge is enabled and your payment method is current. If you recently changed your payment method, it may need time to sync. Try restarting the Mercedes me app.

5. 5

   Try a different RFID card or roaming provider

   If you carry multiple RFID cards, try another network. Roaming providers with broad European coverage (Chargemap, Maingau, Shell Recharge) can fill gaps where Mercedes me Charge does not reach.

6. 6

   Find an alternative charger nearby

   If payment fails on this charger entirely, use the Hyperscreen to find another station nearby. A different charging network may accept your payment method. Filter by the networks you know work with your cards.

Mercedes-Benz EQS Charging Slower Than Expected

You plugged in your EQS at a 300 kW charger expecting close to 200 kW, but the Hyperscreen shows 50 kW. Or your home wallbox is stuck at 3.6 kW instead of 11 kW (or 22 kW if you have the optional upgrade). The EQS has a huge 118 kWh battery that can take a while to warm up. Slow charging is almost always temperature, state of charge, or the charger, not a defect.

Symptoms

• DC fast charging speed well below the 200 kW maximum shown on the Hyperscreen
• AC charging stuck at 3-4 kW instead of 11 kW or 22 kW
• Charging speed drops sharply after reaching 50-60% state of charge
• Charging session starts at reasonable speed but slows within minutes
• The 118 kWh battery takes significantly longer to charge than expected

What to Do

1. 1

   Route to the charger using MBUX navigation

   Enter the charging station as your destination on the Hyperscreen or MBUX. This activates automatic battery preconditioning for the 118 kWh pack. The EQS will display a preconditioning notification. Given the large battery, start routing at least 20-30 minutes before arrival for maximum benefit in cold weather.

2. 2

   Check your state of charge before expecting peak speed

   The EQS reaches 200 kW only at lower state of charge levels. For the fastest DC charging, arrive between 10-20%. If you are above 60%, the speed reduction is normal. With 580 km of range, you often do not need to charge above 80% on road trips.

3. 3

   Verify the charger can deliver the speed you expect

   Check the charger's rated output on the unit itself or in the charging app. A 50 kW charger will never give your EQS more than 50 kW. Look for chargers rated 150 kW or higher to take advantage of the EQS's capabilities. Avoid stalls paired with another vehicle.

4. 4

   Check AC charging settings and wallbox compatibility

   Open the charging settings in MBUX. Confirm the charge current is set to maximum. If you have the optional 22 kW onboard charger, verify your wallbox is 3-phase 32A. For the standard 11 kW charger, you need at least 3-phase 16A.

5. 5

   Check if Plug & Charge negotiated the correct power

   The EQS supports Plug & Charge. Occasionally, authentication issues cause the charger to default to a lower power tier. Unplug from the right rear charge port, wait 30 seconds, and reconnect. Check MBUX for any authentication errors.

6. 6

   Try a different charger

   If the speed is still low after checking all settings, try a different charger. Some chargers degrade over time. Use MBUX navigation or the Mercedes me app to find a high-power charger (150 kW+) nearby.

Session fails to start or charger shows an error

The charger does not begin charging after you plug in and authenticate. This can happen due to communication issues between your vehicle and the charger, or a problem with authentication.

Symptoms

• You plug in and authenticate but the charger displays an error
• The charger screen stays on the welcome screen and does not proceed
• The app shows 'session starting' but nothing happens at the charger
• The connector locks but no power flows

How to Fix It

1. 1

   Unplug, wait 30 seconds, and try again

   The initial communication handshake between your vehicle and the charger sometimes fails. Unplug the connector, wait at least 30 seconds, and reconnect. The second attempt often works.

2. 2

   Try starting the session from the K-Lataus app

   If RFID authentication is not working, open the K-Lataus app, select the station and charger, and start the session through the app instead.

3. 3

   Try a different charger unit at the same station

   If the station has multiple charger units, switch to another one. One unit may have a hardware issue while the others work fine.

4. 4

   Check that your vehicle is ready to charge

   Make sure your vehicle is not in a state that prevents charging, such as a charging schedule being active, the charge port not fully engaged, or a vehicle-side error. Check your vehicle's dashboard for any warnings.

Setting up the K-Lataus app for the first time

K-Lataus has its own dedicated app. First-time setup requires a K-Group account and a payment method linked specifically to the K-Lataus service.

Symptoms

• You are not sure which app to use for K-Lataus charging
• Your K-Group login works on the K-Group website but not in the K-Lataus app
• You cannot find a way to add a payment method for charging
• You cannot find the K-Lataus app in your app store

How to Fix It

1. 1

   Install the K-Lataus app

   Search for 'K-Lataus' in the App Store or Google Play and install it. This is the dedicated app for K-Lataus EV charging. K-Ruoka is for groceries, not for charging.

2. 2

   Log in with your K-Group credentials

   Use the same K-Group username and password you use for other K-Group services. If you do not have a K-Group account yet, you can create one in the app.

3. 3

   Add a payment method in the K-Lataus app

   Go to payment settings in the K-Lataus app and add a credit or debit card. The K-Lataus app manages its own payment methods separately from other K-Group services.

4. 4

   Find a station and start your first session

   Use the map in the K-Lataus app to find a nearby station. Plug in your vehicle, then tap Start in the app or use an RFID card to begin charging.

Parking time limits at grocery store locations

K-Lataus chargers sit in K-Citymarket and K-Market parking lots, which often have monitored parking with time limits. You may get a parking notice if you stay too long.

Symptoms

• You see parking time limit signs (e.g. 2 or 3 hours) in the parking lot
• You received a parking notice even though you were charging
• Your charging session takes longer than the allowed parking time
• Camera-monitored parking is active in the lot

How to Fix It

1. 1

   Check the parking rules when you arrive

   Most K-Citymarket and K-Market parking lots have posted time limits, often 2 to 4 hours, enforced by camera monitoring or a parking operator. These rules apply to EV charging spots too.

2. 2

   Use a parking disc if required

   Many Finnish parking lots still require a parking disc (pysäköintikiekko). Set the arrival time and display it on your dashboard, even if the lot also has camera monitoring.

3. 3

   Set a phone timer to move your car

   If you are shopping while charging, set an alarm so you can return before the parking limit expires. A DC fast charger at 200 kW should get you a substantial charge well within a 2-hour window.

4. 4

   Unplug when charging is complete

   Do not leave your vehicle occupying the charging spot after it finishes. Other EV drivers need the spot, and some parking operators treat finished-but-still-connected vehicles as overstaying.

New stations not appearing in third-party apps

K-Lataus is expanding its network, but newer stations sometimes take weeks to appear in third-party apps and aggregators like PlugShare or Google Maps.

Symptoms

• The K-Lataus app shows a station that does not appear in PlugShare or ABRP
• You planned a route using a third-party app and it skipped a nearby K-Lataus station
• A station listed as 'coming soon' in the K-Lataus app is actually already operational
• Google Maps does not show K-Lataus chargers at a location where you know they exist

How to Fix It

1. 1

   Use the K-Lataus app as the primary source for station locations

   The K-Lataus app is always the most up-to-date source for K-Lataus stations. Third-party apps rely on data feeds that may lag behind actual station openings by days or weeks.

2. 2

   Cross-check with the K-Lataus website

   The K-Lataus website also maintains a station map. Check it if the app is not giving you the information you need or if you want to plan ahead on a larger screen.

3. 3

   Report missing stations to third-party apps

   If you use PlugShare or ABRP regularly, you can add missing stations yourself. This helps other EV drivers find K-Lataus locations that are not yet in the database.

4. 4

   For route planning, combine K-Lataus with other network apps

   When planning a longer trip, check the K-Lataus app alongside ABRP or a similar route planner. The K-Lataus app shows the latest stations, while the route planner optimizes your overall charging stops across all networks.

Slow charging or failed sessions at older units in winter

Some older K-Lataus charger units perform less reliably in extreme cold. Winter in Finland brings temperatures that can affect both the charger hardware and your vehicle's battery.

Symptoms

• The charger takes a long time to initialize in freezing conditions
• Session fails with a generic error after a long handshake attempt
• Charging speed is much lower than expected at a 200 kW station
• The charger screen is slow to respond or displays incorrectly in cold weather

How to Fix It

1. 1

   Precondition your battery before arriving

   If your vehicle has a battery preconditioning feature (most newer EVs do), activate it before arriving at the charger. A warm battery accepts power faster and communicates more reliably with the charger during the initial handshake.

2. 2

   Try unplugging and reconnecting

   In cold weather, the initial handshake between your vehicle and the charger can time out. Unplug, wait 30 seconds, and try again. Sometimes the second attempt connects cleanly.

3. 3

   Try a different charger unit at the same station

   If the station has multiple charger units, one may be more reliable than the other. Older units can have more cold-weather issues than newer installations.

4. 4

   Report consistently problematic chargers

   If a specific charger unit fails repeatedly in cold weather, report it through the K-Lataus app. This helps K-Group identify hardware that needs maintenance or replacement.

5. 5

   Accept that cold weather reduces charging speed

   Even when everything works perfectly, a cold battery charges slower. This is a physics limitation, not a charger fault. The first 10 to 15 minutes of a session may be slower until the battery warms up from the charging current itself.
