Tesla Model S Charging at K-Lataus

Tesla Model S Charger Will Not Start a Session

You plugged in your Model S and nothing is happening. No green light on the charge port, no animation on the 17-inch touchscreen, just silence. Whether you are at a Supercharger, a third-party CCS2 station, or a home wallbox, there are a handful of common reasons the session will not begin.

Symptoms

• Charge port LED stays white or flashes red after plugging in the connector
• 17-inch touchscreen shows no charging animation or displays an error message
• Supercharger stall makes a click but does not begin delivering power
• CCS2 connector at a third-party station locks in but charging never starts
• Tesla app shows 'Not Charging' even though the cable is connected

What to Do

1. 1

   Check the charge port LED color

   Walk to the left rear of the car and look at the charge port light. White means ready but not connected. Blue means communicating. Green means charging. Red or amber means there is a fault. If it is white with the cable plugged in, remove and reseat the connector firmly.

2. 2

   Unplug and replug the connector

   Remove the connector completely, wait five seconds, then reinsert it until you hear the latch click. On CCS2 connectors, make sure both the top (AC pins) and bottom (DC pins) sections are seated properly.

3. 3

   Check for scheduled charging on the touchscreen

   On the 17-inch touchscreen, go to Controls, then Charging. If scheduled charging is active, you will see the planned start time. Tap to disable it or select 'Charge Now' to override the schedule.

4. 4

   Authorize the session at non-Tesla chargers

   At third-party CCS2 stations, check whether the charger requires you to start the session through an app, RFID card, or contactless payment. Plug & Charge works at supported stations, but many still require manual authorization.

5. 5

   Try a different stall or charger

   If you are at a Supercharger, move to a different stall. If you are at a third-party station, try the other connector. A faulted charger looks identical to a working one from the outside.

6. 6

   Restart the touchscreen

   Hold both scroll wheels on the steering wheel for about 10 seconds until the 17-inch touchscreen goes black and reboots. This resets the charging controller and fixes some communication glitches. The car stays on during the reboot.

Tesla Model S Payment Failed at Charging Station

You are plugged in and the charger is waiting for payment, or the Supercharger session will not start because of a billing issue. Payment problems are one of the most common reasons drivers get stuck at chargers, and the Model S has multiple ways to pay depending on where you are charging.

Symptoms

• Supercharger session will not start and the Tesla app shows a payment error
• Third-party CCS2 charger displays 'Authorization failed' after tapping your card
• RFID card is not recognized by the charger's reader
• Plug & Charge does not activate at a supported station
• Contactless bank card is rejected by the charger's payment terminal

What to Do

1. 1

   Check your Tesla account payment method

   Open the Tesla app on your phone. Go to Account, then Payment. Verify your credit card is current and has not expired. If the card was replaced, update the details. Supercharger sessions will not start without a valid payment method on file.

2. 2

   Try a different payment method at the charger

   If your RFID card failed, try contactless with your bank card or phone. If contactless failed, try the charger operator's app. Having at least two payment methods gives you a backup when one does not work.

3. 3

   Scan the charger QR code for browser payment

   Most public chargers have a QR code on the unit. Scanning it with your phone opens the operator's payment page in your browser. You can usually pay with a credit card directly without downloading their app.

4. 4

   Check your banking app for blocked transactions

   Open your banking app and look for flagged or declined transactions. Some banks require you to approve the charge manually. Approve it and retry the payment at the charger.

5. 5

   Try Plug & Charge by replugging

   If the charger supports Plug & Charge, unplug the CCS2 connector from your Model S, wait a few seconds, and replug. Payment should authorize automatically through the cable. This only works if your Tesla account has Plug & Charge enabled and the charger supports ISO 15118.

6. 6

   Move to a Supercharger or a different station

   If you cannot resolve the payment issue, find a Tesla Supercharger using the nav on the 17-inch touchscreen. Supercharger billing is handled entirely through your Tesla account, bypassing third-party payment systems.

Tesla Model S Charging Slower Than Expected at Charger

You pulled into a Supercharger expecting 250 kW and the 17-inch touchscreen shows 80 kW. Or your home wallbox is crawling at 3 kW instead of 11 kW. The Model S has one of the fastest charging curves on the road, but reaching peak speed depends on battery temperature, state of charge, and a few settings you can check in under a minute.

Symptoms

• DC fast charging power well below 250 kW on the touchscreen despite a rated charger
• AC home charging stuck at 3-4 kW instead of the expected 11 kW on 3-phase
• Charging speed drops sharply after 40-50% on the touchscreen during DC fast charging
• Supercharger shows significantly lower kW than neighboring stalls
• Non-Tesla CCS2 charger delivers far less power than its rated maximum

What to Do

1. 1

   Check if the battery was preconditioned

   On the 17-inch touchscreen, tap the charging icon. If you see a snowflake icon or a message about conditioning, the battery was not warm enough when you arrived. Next time, navigate to the charger using Tesla nav at least 20-30 minutes before arrival so preconditioning kicks in automatically.

2. 2

   Check your current state of charge

   If you are above 50%, the slower speed is expected on the 95 kWh NCA pack. Peak power happens roughly between 5-30%. For the fastest charging stops on a road trip, arrive between 10-20%.

3. 3

   Move to an unpaired Supercharger stall

   Look at the stall numbers. If they are labeled in A/B pairs (3A/3B, 4A/4B), pick a stall where the paired stall is empty. At V3 or V4 Superchargers with the Magic Dock or the new V4 cable, this is not a concern.

4. 4

   Check the AC charge current limit on the touchscreen

   Go to Controls, then Charging on the touchscreen. Look for the charge current setting. Make sure it is set to the maximum amperage. This only affects AC charging at home or destination chargers, not Supercharging.

5. 5

   Try a different charger or stall

   If speeds remain low, the charger hardware may be degraded. Try another stall at the same location. On non-Tesla CCS2 stations, check the charger display for error codes or reduced power notices.

6. 6

   Check for a Tesla software update

   Go to Controls, then Software on the touchscreen. If an update is pending, install it. Tesla has adjusted charging curves through over-the-air updates in the past, sometimes improving peak speeds.

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.
