Why Your Charging Speed May Differ

The Tesla Model 3 supports up to 175 kW DC charging. K-Lataus chargers deliver up to 200 kW. Your car's maximum intake is the limiting factor here, capping speed at 175 kW even on a faster charger.

  • Charging slows down above 80% state of charge on most EVs, including the Tesla Model 3.
  • Cold weather reduces charging speed. The Tesla Model 3 supports battery preconditioning, which helps.
  • If multiple cars share the same K-Lataus station, power may be split between stalls.

Tesla Model 3 Charging Problems

Tesla Model 3 Charger Won't Start a Charging Session

You have plugged in your Model 3, the charge port light is doing something weird, and nothing is happening. This is one of the most common frustrations for EV drivers. The good news is that it is almost always fixable on the spot. The cause is usually authentication, the charge port latch, or the charger itself.

Symptoms

  • Charge port LED flashes amber or red after plugging in the CCS2 connector
  • Touchscreen shows an error message instead of the charging screen
  • Charger display says 'Waiting for vehicle' or 'Authentication failed'
  • Charge port will not open when pressing the button on the connector
  • Supercharger session does not start automatically after plugging in

What to Do

  1. 1

    Unplug and replug the connector firmly

    Pull the connector out completely. Wait 5 seconds. Push it back in firmly until you hear a click and the charge port LED turns green or starts pulsing. On CCS2, the lower DC pins need to seat fully.

  2. 2

    Check the touchscreen for error messages

    Look at the charging screen on the touchscreen. It will tell you if there is an error, if scheduled charging is active, or if the car is waiting for something. If Scheduled Charging is delaying the session, tap 'Charge Now' to override it.

  3. 3

    Authenticate with the charging network

    At non-Tesla chargers, open the network's app (Ionity, Shell Recharge, or whichever network). Start the session through the app, or tap your RFID card on the charger. At Tesla Superchargers, this step is automatic.

  4. 4

    Try the manual charge port release if the port is stuck

    If the charge port will not open, try tapping your Tesla key card on the B-pillar and pressing the charge port door. You can also open it from the touchscreen under Controls. In freezing weather, pour lukewarm water around the port to melt ice. Never force it.

  5. 5

    Restart the touchscreen

    Hold both scroll wheels on the steering wheel for about 10 seconds until the Tesla logo appears. This restarts the infotainment system and can clear communication errors between the car and the charger.

  6. 6

    Try a different charger or stall

    If nothing works, the charger may be faulty. Move to a different stall or station. At Superchargers, the Tesla app shows stall availability in real time.

Tesla Model 3 Payment Failed at the Charging Station

You plugged in, everything looked fine, and then the charger says payment failed. Or the session will not start because authentication did not go through. Payment problems are different at Tesla Superchargers versus non-Tesla CCS2 chargers, so the fix depends on where you are.

Symptoms

  • Charger display shows 'Payment failed' or 'Transaction declined' after tapping a card
  • Tesla Supercharger session will not start and the Tesla app shows a billing error
  • Non-Tesla CCS2 charger shows 'Authentication failed' after scanning RFID or using an app
  • Contactless payment terminal on the charger does not respond to your bank card
  • Charging starts but stops after a few seconds with a payment-related error on the charger screen

What to Do

  1. 1

    Check if this is a Tesla Supercharger or a non-Tesla station

    At Tesla Superchargers, payment is automatic through your Tesla account. At non-Tesla CCS2 chargers, you need to authenticate separately. The fix is completely different for each.

  2. 2

    For Superchargers: update your payment method in the Tesla app

    Open the Tesla app, go to Account, then Payment. Check that your card is current and not expired. Add a new card if needed. Then try the Supercharger again. The session should start automatically after plugging in.

  3. 3

    For non-Tesla chargers: authenticate through the network app

    Open the charging network's app (Ionity, Shell Recharge, Virta, or whichever network runs the charger). Select the charger, start the session, then plug in. Make sure the app shows your payment method is valid.

  4. 4

    Try a different payment method at the charger

    If the contactless terminal failed, try the network's app instead. If the app failed, try an RFID card. If you do not have the network's app, some chargers accept ad-hoc payments through a QR code on the charger.

  5. 5

    Call your bank if repeated transactions are declined

    If your card keeps getting declined at chargers, your bank may be blocking charging transactions. Call the number on the back of your card and let them know you are making EV charging payments. They can whitelist these merchants.

  6. 6

    Move to a different charger if the payment terminal is broken

    If the charger's payment terminal is physically unresponsive, try a different stall. Report the broken terminal through the network's app so they can fix it.

Tesla Model 3 Charging Slower Than Expected at Charger

You plugged in your Model 3 expecting 175 kW and the touchscreen shows 50 kW. Or your home wallbox is stuck at 3 kW instead of 11 kW. Slow charging on the Model 3 is almost never a defect. It is usually the battery temperature, a charger limitation, or a setting you can fix on the touchscreen in under a minute.

Symptoms

  • DC fast charging power well below the 175 kW maximum shown on the touchscreen
  • AC home charging stuck at 3-4 kW instead of the expected 11 kW
  • Charging speed drops sharply after reaching 50-60% on the touchscreen
  • Supercharger shows lower kW than the stall is rated for
  • Touchscreen charging animation shows a slow trickle instead of rapid charging

What to Do

  1. 1

    Check the battery temperature on the touchscreen

    Tap the charging icon on the touchscreen. If the battery is cold, you will see a snowflake icon or a message about reduced charging speed. To fix this, use the Tesla nav to route to a Supercharger. The car will automatically precondition the battery during the drive.

  2. 2

    Check your state of charge

    If you are above 80%, the slower speed is expected. For the fastest DC charging, arrive between 10-20%. The Model 3 LFP hits peak power in the 10-50% range.

  3. 3

    Move to an unpaired Supercharger stall

    Look at the stall numbers. If they are labeled in pairs (1A/1B, 2A/2B), pick a stall where the paired stall is empty. At V3 or V4 Superchargers, this is not an issue.

  4. 4

    Check the AC charge current limit

    On the touchscreen, go to Controls, then Charging. Look for the charge current slider or setting. Make sure it is set to the maximum value. This only affects AC charging, not Supercharging.

  5. 5

    Try a different charger or stall

    If speeds are still low, the charger may be degraded. Try a different stall at the same location. On non-Tesla CCS chargers, some stations deliver less power than advertised.

  6. 6

    Check for a software update

    Go to Controls, then Software on the touchscreen. If an update is available, install it. Tesla occasionally adjusts charging curves through software updates.

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.
