Mer Charging Guide

First Time Charging with Mer?

Here is what you need to know before your first session.

• Download the Mer app or have a contactless bank card ready. Payment options include app, RFID, contactless.
• Check which connector your car uses. Mer stations have CCS2 connectors.
• Plug in first, then authorize. Most Mer chargers require you to connect the cable before starting the session.
• If the screen shows a message you do not understand, the EVcourse app can read it for you. It works with any charger screen, any language.

Understanding Mer Pricing

Charging network pricing is more complex than it looks. The per-kWh rate shown in the app or on the charger is not always the full cost. Here is what to watch for.

Extra Charges to Watch For

The per-kWh price is not always the full picture. These additional fees can add up, especially on short sessions or when you forget to unplug.

• → Idle fees. Many DC fast chargers charge per minute once your battery is full but the car is still plugged in. This can be €0.10-0.50 per minute. Set a reminder to move your car when charging is done.
• → Session start fees. Some networks charge a flat fee (€0.50-2.00) just to start a session, on top of the per-kWh rate. This hits harder on short top-up sessions.
• → Per-minute billing. Some chargers bill per minute instead of per kWh. If your car charges slowly (cold battery, high state of charge, or an older model), per-minute billing is much more expensive. Check the billing model before you plug in.
• → Time-of-day pricing. Some networks charge more during peak hours (daytime) and less at night. If you have flexibility, charging off-peak can save money. For example, some networks have an idle fee only during business hours.

How to Pay at Mer

Mer supports the following payment methods. Availability may vary by location.

• Mer app. Download the app, create an account, and add a payment method. Start and stop charging sessions from your phone.
• RFID card. Tap a registered RFID card on the charger to start. These need to be ordered in advance from Mer or a roaming partner. Most drivers use the app instead.
• Contactless payment. Tap your bank card or phone (Apple Pay, Google Pay) directly on the charger. No account needed. The simplest option, but sometimes at a slightly higher rate.

Tips for Charging at Mer

• Mer accepts app, RFID, and contactless payment. Contactless is the quickest way to start if you do not have the app installed yet.
• Many Mer locations are at retail sites, hotels, and business parks. Check the app to see if there are AC chargers alongside the DC fast chargers at your destination.
• If you use an RFID card from another provider, verify roaming compatibility before arriving. Not all third-party cards work at every Mer station.
• Mer stations are powered by renewable energy. If green charging matters to you, this is one of the networks that backs it up with actual energy sourcing.
• The Mer app shows live availability and pricing per location. Prices may vary between countries and station types.

Common Issues with Mer

• Station density is limited compared to larger networks, so Mer works better as part of a multi-network strategy for longer trips.
• Some older Mer stations may have lower power output than the 300 kW maximum. Check the station specs in the app before counting on top speed.
• RFID roaming can be unreliable at certain locations. Keep the Mer app as a backup payment method.
• In the UK market, some drivers report confusion between Mer-branded and legacy-branded stations that have been rebranded.

Charger Not Working?

If a Mer charger will not start, charges too slowly, or gives an error, check our Mer troubleshooting guide for network-specific fixes. Or see the general troubleshooting guide for step-by-step help with any charger.

You can also report the issue through the Mer app. Reporting broken chargers helps the network fix them faster and helps other drivers avoid the same problem.
