Mercedes-Benz EQS Charging at ChargePoint

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.

App shows "Available" but the charger is physically broken

The ChargePoint app shows a green status for a charger, but when you arrive, the unit is visibly damaged, has a blank screen, or displays an out-of-service message. This happens because ChargePoint's availability status depends on the charger reporting its own state, and a broken charger sometimes cannot report that it is broken.

Symptoms

• App shows the charger as available with a green icon
• Charger screen is blank, cracked, or showing an error message on site
• The connector is physically damaged or the cable is severed
• Other drivers at the station confirm the charger has been broken for days

How to Fix It

1. 1

   Check the other chargers at the same station

   ChargePoint stations often have multiple units. If one is broken, another unit nearby may work fine. Use the app to see all connectors at the location.

2. 2

   Report the broken charger in the ChargePoint app

   Open the station detail in the ChargePoint app, find the specific charger, and report the issue. Select the most accurate problem description. This updates the status for other drivers and alerts the station operator.

3. 3

   Check recent driver reports in the app

   The ChargePoint app sometimes shows recent check-ins or reports from other drivers. Before driving to a station, scroll down on the station detail page to see if anyone has reported issues recently.

4. 4

   Find the nearest alternative station

   In the ChargePoint app, tap "Find nearby" or zoom out on the map. Filter for DC fast chargers if you need speed. You can also check Google Maps or A Better Route Planner for non-ChargePoint alternatives.

RFID tap not registering

You tap your ChargePoint card on the reader and nothing happens. No beep, no screen change, no session. The RFID readers on ChargePoint stations can be finicky, especially on older European units.

Symptoms

• Tapping the RFID card produces no response from the charger
• The charger beeps but then shows "Authentication failed"
• The card works at some ChargePoint stations but not this one
• The RFID reader area is hard to locate on the charger

How to Fix It

1. 1

   Find the correct RFID reader location

   On ChargePoint stations, the RFID reader is sometimes in an unexpected spot. Look for a small RFID symbol, usually on the front face of the charger or near the screen. On some European units, it is on the side panel.

2. 2

   Hold the card flat and steady for three seconds

   Do not tap and pull away quickly. Press the card flat against the reader area and hold it still for a full three seconds. Some readers need this extra time.

3. 3

   Remove your card from any wallet or phone case

   If your ChargePoint card is in a wallet with other RFID cards or near your phone, interference can prevent the reader from detecting it. Hold the card alone against the reader.

4. 4

   Start the session from the ChargePoint app instead

   Open the ChargePoint app, find the station, select the specific charger, and tap "Start." This sends a start command over the network and does not rely on the physical RFID reader at all.

5. 5

   Check if your card is activated

   New ChargePoint RFID cards need to be activated in the ChargePoint app or on the website. Go to Account, then Cards, and verify your card is listed and active.

Session auto-terminates at 80%

Your charging session stops automatically when your battery reaches around 80%, even though you did not set a limit and wanted to charge further. Some ChargePoint stations, particularly those operated by local CPOs, have a configuration that ends sessions at 80% to free up the charger for the next driver.

Symptoms

• Charging stops at exactly 80% state of charge
• The ChargePoint app shows the session as "Complete" at 80%
• No error message on the charger, it simply stops
• Your car is still ready to accept more charge

How to Fix It

1. 1

   Check if this is a station policy

   Some station operators set an 80% cutoff on DC fast chargers to maximize charger availability. This is not a fault. Check the station detail in the ChargePoint app or look for signage at the station explaining time or charge limits.

2. 2

   Start a new session

   After the session ends at 80%, you can often start a new session on the same charger to continue charging. Unplug, wait 10 seconds, plug back in, and authenticate again.

3. 3

   Check your car's own charge limit

   Some EVs have a default charge limit set to 80% in the car's settings. Check your car's infotainment system under charging settings. If the limit is set to 80%, the car itself is stopping the session, not ChargePoint.

4. 4

   Switch to a different station if you need to charge above 80%

   If the 80% cutoff is a station policy and you need more charge, find a station without this restriction. AC chargers at destinations are usually a better choice for topping up above 80% because DC charging is very slow above that level anyway.

Waitlist feature not working

ChargePoint offers a waitlist feature that is supposed to notify you when a busy charger becomes available. In practice, the notifications are unreliable, especially at European stations.

Symptoms

• You joined the waitlist but never received a notification
• The notification arrived long after the charger became available
• The waitlist button is not available for some stations
• You received a notification but the charger was already taken by someone else

How to Fix It

1. 1

   Enable push notifications for the ChargePoint app

   Go to your phone's notification settings and make sure ChargePoint notifications are allowed. On iOS, check Settings, then Notifications, then ChargePoint. On Android, check App Info, then Notifications.

2. 2

   Stay within a reasonable distance of the station

   The waitlist is most useful when you are nearby, at a shop or restaurant within a few minutes of the charger. By the time you drive 15 minutes back to a station, the charger may already be taken again.

3. 3

   Do not rely solely on the waitlist

   Treat the waitlist as a nice-to-have, not a guarantee. Check the app manually every few minutes for availability updates, or look for an alternative station while you wait.

4. 4

   Check if the station supports the waitlist feature

   Not all ChargePoint stations have the waitlist enabled, particularly CPO-operated stations using ChargePoint hardware. If you do not see a waitlist option on the station page, the feature is not available there.

App interface confusing for European users

ChargePoint's app was designed primarily for the US market. European users sometimes encounter US-centric defaults, unfamiliar terminology, or features that do not apply in Europe.

Symptoms

• App defaults to miles instead of kilometers
• Pricing displayed in unexpected formats or currencies
• Filter options include connector types not used in Europe, like NACS
• Station details reference US-specific payment methods or loyalty programs
• Map loads centered on the US instead of your actual location

How to Fix It

1. 1

   Set your region and units in the app settings

   Open the ChargePoint app, go to Account or Settings, and look for region, language, or unit preferences. Set distance to kilometers and currency to your local currency.

2. 2

   Filter for CCS2 connectors

   When searching for stations, use the filter to show only CCS2 (the European DC fast charging standard). This hides US-only connector types from your results.

3. 3

   Check the station detail for European pricing

   Tap on a station to see the pricing breakdown. European ChargePoint stations typically show pricing in EUR, SEK, NOK, or GBP per kWh, sometimes with an additional per-minute fee after a certain duration.

4. 4

   Ignore US-specific features

   Features like ChargePoint Home integration or certain fleet management tools are designed for the US market. If something in the app does not seem relevant, it probably is not meant for European users.

CPO-operated station behaves differently than expected

Some stations use ChargePoint hardware and appear in the ChargePoint app, but they are owned and operated by a local charge point operator. These stations may have different pricing, access rules, or session limits than ChargePoint-owned stations.

Symptoms

• Pricing at the station does not match what you expected from ChargePoint
• Your ChargePoint account works but the session has unexpected restrictions
• The charger looks like ChargePoint but has another company's branding on it
• Customer support refers you to a different company for this station

How to Fix It

1. 1

   Check who operates the station

   In the ChargePoint app, the station detail page usually shows the operator or network name. If it says something other than ChargePoint, the station is CPO-operated and may have its own rules.

2. 2

   Read the pricing and terms on the station detail page

   CPO-operated stations set their own pricing. Check the ChargePoint app for the exact per-kWh rate and any time-based fees or session limits before you plug in.

3. 3

   Try the CPO's own app if ChargePoint authentication fails

   Some CPO stations accept ChargePoint cards but work more reliably with the operator's own app or RFID card. Look for the operator's name on the charger and download their app.

4. 4

   Contact the station operator for site-specific issues

   For problems like broken hardware, pricing errors, or access restrictions at a CPO-operated station, contact the operator directly. Their contact information is usually on the charger or in the station detail in the ChargePoint app.
