Tesla Model S Charging at Helen

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.

Charging section buried in the Helen app

The Helen app handles electricity contracts, energy consumption, and EV charging in one place. Finding the charging features can take a few taps if you are used to dedicated charging apps.

Symptoms

• You opened the Helen app but cannot find how to start a charging session
• The app shows your electricity bill but no charging options
• You found a station list but cannot figure out how to initiate charging
• The charging feature seems to disappear after app updates

How to Fix It

1. 1

   Look for the EV charging or e-mobility section

   In the Helen app, EV charging is usually under a dedicated menu item like 'Charging' or 'E-mobility.' It is not on the main dashboard with your electricity contract. Tap the menu icon and scroll through the options.

2. 2

   Make sure EV charging is activated on your Helen account

   If you are a Helen electricity customer, EV charging may need to be activated separately. Check your account settings or the Helen website. You may need to accept additional terms for the charging service.

3. 3

   Update the app to the latest version

   Helen occasionally reorganizes the app layout. If the charging section has moved after an update, check the main menu, bottom navigation, or any new tabs that appeared. The latest version will have the current layout.

4. 4

   Try the Helen Charging web portal as a backup

   If the app is giving you trouble, Helen also offers a web-based portal for starting sessions and viewing history. Search for 'Helen lataus' in your browser.

RFID card registration through your Helen energy account

To use an RFID card at Helen chargers, you need to register it through your Helen energy account. This is different from networks where you simply order a card and it works.

Symptoms

• You received a Helen RFID card but it does not start the charger
• Your third-party RFID card is not accepted at Helen stations
• The charger shows 'Card not recognized' when you tap
• You are not sure how to link your RFID card to your Helen account

How to Fix It

1. 1

   Register your RFID card in the Helen app or on helen.fi

   Log in to your Helen account (app or website) and navigate to the charging or RFID section. Enter the card number printed on your RFID card. The registration may take a few minutes to activate.

2. 2

   Wait 10 to 15 minutes after registration

   The card activation is not always instant. After registering, wait at least 10 minutes before trying the card at a charger. If it still does not work after 30 minutes, contact Helen support.

3. 3

   Check if your RFID card is from a compatible roaming network

   Helen accepts some third-party RFID cards through roaming agreements, but not all. Cards from Virta-connected networks are more likely to work. If your card is from a network without a roaming agreement with Helen, it will be rejected.

4. 4

   Use the Helen app to start the session as a workaround

   While you sort out the RFID issue, the Helen app can start a session directly. Select the charger on the map, tap start, and the session begins without needing a physical card.

Plugging into an AC charger when you expected DC fast charging

Helen operates both AC chargers (11 to 22 kW) and DC fast chargers (up to 200 kW) in the Helsinki area. Some locations have both types side by side, and it is easy to plug into the wrong one.

Symptoms

• Charging speed is only 11 kW or 22 kW at a station you expected to be fast
• The connector is Type 2 instead of CCS2
• Your vehicle's dashboard shows AC charging, not DC
• The charger unit looks smaller and simpler than a typical fast charger

How to Fix It

1. 1

   Check the charger type before plugging in

   DC fast chargers are larger units with thick CCS2 cables. AC chargers are smaller, often wall-mounted or on a slim post, with a Type 2 connector. If the connector is Type 2 only, it is an AC charger.

2. 2

   Use the Helen app to identify charger types at each location

   The app shows whether a station offers AC, DC, or both. Filter for DC fast chargers if you need a quick charge. Station listings should indicate the maximum power output.

3. 3

   If you need speed, unplug and move to the DC unit

   If you accidentally plugged into an AC charger and need faster charging, stop the session, unplug, and move your vehicle to the DC fast charger at the same location (if available).

4. 4

   AC charging is fine if you have time

   If you are parked for several hours (shopping, at work, overnight), an AC charger at 11 to 22 kW will add meaningful range. AC charging is also gentler on your battery than frequent DC fast charging.

Parking time limits at urban charging locations

Some Helen chargers in Helsinki are installed in areas with parking time restrictions. You may get a parking fine if you exceed the posted limit, even while charging.

Symptoms

• You see a parking time limit sign near the charger (e.g. 2 or 4 hours)
• You received a parking fine despite being plugged in and charging
• Your charging session takes longer than the posted parking limit
• You are not sure if the parking limit applies while charging

How to Fix It

1. 1

   Read the parking signs before plugging in

   Check the parking signs near the charging spot. In Helsinki, many on-street and parking garage spots have time limits (often 2 or 4 hours). These limits typically apply regardless of whether you are charging.

2. 2

   Set a timer on your phone

   If there is a time limit, set a phone alarm so you can move your vehicle before the limit expires. Even if charging is not complete, a parking fine is not worth the extra kWh.

3. 3

   Use a parking disc if required

   In Finland, many time-limited parking areas require a parking disc (pysäköintikiekko) displayed on your dashboard. Set the arrival time and place it visibly.

4. 4

   Choose locations without time restrictions for longer sessions

   If your vehicle charges slowly on AC and you need several hours, use the Helen app to find chargers in locations without strict parking time limits, such as certain parking garages or less restricted areas.

Limited coverage outside Helsinki metropolitan area

Helen's charging network is concentrated in Helsinki, Espoo, and Vantaa. If you are traveling outside the capital region, Helen chargers become scarce or unavailable.

Symptoms

• The Helen app shows no stations along your route outside Helsinki
• You assumed Helen would have chargers at your destination but there are none
• The nearest Helen charger is 50 km or more away
• You planned a road trip relying on Helen and now need alternatives

How to Fix It

1. 1

   Check coverage before you travel

   Open the Helen app or website and zoom out on the map. Helen's stations are clustered in the Helsinki metropolitan area. If your destination is outside this zone, you will need another network.

2. 2

   Install backup charging apps for other networks

   For travel outside Helsinki, install apps for networks with broader Finnish coverage like K-Lataus, ABC-lataus, Virta, or Recharge. Having multiple apps ready means you always have options.

3. 3

   Use a roaming RFID card for multi-network access

   A roaming RFID card from Virta or PlugSurfing lets you access chargers from multiple networks without installing each network's app. Roaming rates may be slightly higher, but the convenience is worth it for occasional use.

4. 4

   Plan charging stops using a multi-network route planner

   Apps like A Better Routeplanner (ABRP) show chargers from all networks. Enter your vehicle model and destination, and the app will suggest optimal charging stops regardless of which network operates them.
