Why Your Charging Speed May Differ

The Smart #1 supports up to 150 kW DC charging. K-Lataus chargers deliver up to 200 kW. Your car's maximum intake is the limiting factor here, capping speed at 150 kW even on a faster charger.

  • Charging slows down above 80% state of charge on most EVs, including the Smart #1.
  • Cold weather reduces charging speed. The Smart #1 supports battery preconditioning, which helps.
  • If multiple cars share the same K-Lataus station, power may be split between stalls.

Smart #1 Charging Problems

Smart #1 Pro Plus Charger Will Not Start a Session

You plugged the connector into your Smart #1, but the charger is not responding. No charging indicator, no session starting, nothing happening. This is almost always a charger-side or authentication issue, not a problem with the car. Let us work through it.

Symptoms

  • The CCS2 or Type 2 connector is in but nothing happens
  • The charger screen shows an error or stays on the welcome screen
  • The Smart #1 dashboard does not show a charging session
  • You hear the connector lock but charging does not begin
  • The charging app shows the charger as available even though you are plugged in

What to Do

  1. 1

    Authenticate with the charger first

    Tap your RFID card, open the charging network app, or use contactless payment on the charger. Wait for the charger screen to confirm the session before plugging in.

  2. 2

    Remove and reinsert the connector

    Unlock the connector (press the button on the charger handle), remove it fully, wait 10 seconds, then push it back in firmly until it clicks and locks.

  3. 3

    Lock and unlock the car

    Use the key fob or Smart app to lock the car, wait 15 seconds, then unlock it. This can reset the charging system if it is in a fault state.

  4. 4

    Check the charge port for ice or debris

    Open the charge port flap on the rear left of the Smart #1 and inspect it. In winter, warm the port gently with your hands or use lukewarm water if ice is present. Never use hot water.

  5. 5

    Restart the infotainment system

    Press and hold the power button on the center screen for 10 seconds to restart the system. Wait for it to boot fully, then try plugging in again.

  6. 6

    Try a different charger

    If the session still will not start, the charger is likely faulty. Move to another charger at the station or a different location.

Smart #1 Pro Plus Payment Failed at Charging Station

You are ready to charge your Smart #1, but the payment will not go through. The RFID card does not register, the app gives an error, or your bank card gets declined. This is a charger and payment issue, not a car issue. Here is what to do.

Symptoms

  • RFID card tap does nothing at the charger
  • Charging app shows a payment or authorization error
  • Contactless bank card is declined
  • Charger displays a payment error code
  • Session starts but stops immediately with a billing message

What to Do

  1. 1

    Check which payment methods the charger accepts

    Look at the stickers and screen on the charger for accepted networks, apps, and card types. If your payment method is not listed, you need to try something else.

  2. 2

    Switch to a different payment method

    Try a different RFID card, a different charging app, or a contactless bank card. Having multiple options is essential for public charging in Europe.

  3. 3

    Check your available balance

    Open your banking app and verify you have at least 80 EUR available to cover the pre-authorization hold. If not, use a card with a higher balance.

  4. 4

    Hold the RFID card steadily

    Place the RFID card flat against the reader and hold it for 2-3 seconds. Do not tap and remove quickly. Some readers are slow to respond.

  5. 5

    Cancel and retry the session

    If a previous attempt is stuck, cancel it through the app first. Wait a minute, then start a fresh session from scratch.

  6. 6

    Try the other charger unit

    If the payment hardware is faulty on one unit, the neighboring charger at the same station may work fine.

Smart #1 Pro Plus Charging Slower Than Expected Speed

Your Smart #1 should charge at up to 150 kW on DC and 22 kW on AC, but the numbers on the screen tell a different story. Maybe you are stuck at 40 kW on a fast charger, or your wallbox is only delivering 7 kW. Here is what is going on and how to fix it.

Symptoms

  • DC fast charging well below the 150 kW maximum
  • AC charging stuck at 7 or 11 kW instead of 22 kW
  • Charging speed drops sharply after 50-60% state of charge
  • The dashboard shows lower power than the charger rating
  • Charging from 10% to 80% takes much longer than the advertised 30 minutes

What to Do

  1. 1

    Use navigation to activate preconditioning

    Set the DC charger as your destination in the Smart #1's built-in navigation. This activates battery preconditioning, warming or cooling the battery to the ideal temperature before you arrive.

  2. 2

    Check your state of charge

    If you are above 60%, the slower speed is expected. For the fastest DC charging, arrive between 10-20% and charge to 80%.

  3. 3

    Verify the charger's actual output

    Check the charger display for its rated power. If it says 50 kW, that is your maximum regardless of the Smart #1's 150 kW capability. Look for chargers rated 150 kW or higher.

  4. 4

    Check if the charger is shared

    If another car is using the adjacent connector on the same charger unit, you may be sharing power. Move to a charger with no other user if possible.

  5. 5

    For AC, verify three-phase connection

    To get 22 kW AC, your wallbox must be wired for three-phase at 32A. Check with your electrician. If you only have single-phase, the maximum is about 7.4 kW.

  6. 6

    Try a different charger

    If speeds are still low after checking everything, the charger may be degraded. Try another charger at the same station or a different location.

Common K-Lataus Issues

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.

K-Lataus App Tips

  • Install the K-Lataus app separately from K-Ruoka. They share your K-Group login but serve different purposes. K-Lataus is specifically for EV charging.
  • The K-Lataus app shows real-time charger status. Check availability before driving to a station, especially at popular K-Citymarket locations.
  • New K-Lataus stations appear in the K-Lataus app first, often weeks before they show up in third-party apps. Use it as your primary source when planning stops at K-Group locations.
  • Your charging history in the K-Lataus app shows energy delivered, duration, and cost per session. Use it to track your charging patterns and costs over time.
  • Make sure your K-Lataus app is updated regularly. K-Group adds new stations and features, and an outdated app may miss the latest additions.

Payment Tips

  • The K-Lataus app is the most reliable payment method. Open the app, select the charger, and tap start.
  • You can also use a compatible RFID card. Check the K-Lataus app or website for supported RFID options.
  • K-Lataus pricing is per kWh. The app displays the current rate before you start each session. No surprise charges.
  • Make sure you have a payment method saved in the K-Lataus app before you arrive at the charger.
