Why Your Charging Speed May Differ

The Hyundai Kona Electric supports up to 105 kW DC charging. Tesla Supercharger chargers deliver up to 250 kW. Your car's maximum intake is the limiting factor here, capping speed at 105 kW even on a faster charger.

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

Hyundai Kona Electric Charging Problems

Hyundai Kona Electric Charger Won't Start? Fix Guide

You have plugged the cable into your Kona Electric, but nothing is happening. No charging indicator, no progress on the screen. The Kona Electric's charge port is in the front, under a flap on the nose of the car. This unusual location sometimes causes cable reach problems. But the issue is usually authentication, a car setting, or the charger itself.

Symptoms

  • CCS2 or Type 2 cable plugged in but no charging indicator on the dashboard
  • Charge port LED stays off or flashes an error pattern
  • Charger screen shows an error or stays on the start screen
  • Bluelink app shows the car is not connected to a charger
  • Charging begins briefly then stops within seconds

What to Do

  1. 1

    Open the front charge port and check the cable

    The charge port is on the front of the car, under a flap. Press the flap to open it. If it is stiff, press more firmly. Insert the CCS2 connector straight in until you hear a click. The LED should light up.

  2. 2

    Make sure you are parked nose-in

    Unlike most EVs with rear charge ports, the Kona Electric needs to face the charger. If you backed in, the cable probably will not reach. Pull out and park nose-first.

  3. 3

    Authenticate with the charger

    Tap your RFID card, use the charging network's app, or try contactless payment. The Kona Electric does not have Plug & Charge, so you will always need to authenticate manually at DC fast chargers.

  4. 4

    Check for a charging schedule

    On the infotainment screen, go to EV settings, then Scheduled Charging. Disable any active schedule or tap 'Charge Now' to override it.

  5. 5

    Unplug, wait 30 seconds, and try again

    Remove the cable, wait 30 seconds, reconnect, and re-authenticate. This resets both the car and charger communication.

  6. 6

    Try a different charger

    If the session still will not start, the charger is likely faulty. Try another stall or station. Report the broken charger through the network's app.

Hyundai Kona Electric Charger Payment Failed at Station

You are at a public charger with your Kona Electric, the cable is in, but payment will not go through. The charger shows an error, the app is not cooperating, or your RFID card gets no response. The Kona Electric does not support Plug & Charge, so you always need to authenticate manually. Here is how to work through payment problems.

Symptoms

  • Charger screen shows 'payment failed' or 'authorization error'
  • RFID card tapped but the charger does not respond
  • Charging network app shows an error or hangs during payment
  • Contactless card payment declined at the charger terminal
  • QR code on the charger leads to a page that will not load

What to Do

  1. 1

    Try a different payment method

    If RFID failed, open the charging app. If the app failed, try contactless with a credit or debit card. Having multiple options is the fastest way past payment issues.

  2. 2

    Check your charging app account

    Open the app and verify your payment method is valid. Look for expired cards, low prepaid balances, or account restrictions. Update your card details if needed.

  3. 3

    Scan the QR code on the charger

    Many chargers have a QR code that opens a web-based payment page. This lets you pay without an account or app. Scan it with your phone camera.

  4. 4

    Try a different stall at the same station

    If one charger's payment terminal is broken, the next one over may work fine. Walk to the next stall and try the same payment method.

  5. 5

    Try a different charging station

    If all stalls at this location have payment issues, the entire station may have a connectivity problem. Head to a nearby alternative station.

Hyundai Kona Electric Charging Slower Than Expected

The Kona Electric supports up to 100 kW DC fast charging, which is solid but noticeably slower than the 233 kW that 800V Hyundai models can reach. If your Kona is pulling 30 kW at a charger rated for much more, something is off. In most cases, slow charging comes down to battery temperature, state of charge, or the charger not delivering its full rated output.

Symptoms

  • DC fast charging speed well below the 100 kW maximum
  • AC charging stuck at 3-4 kW instead of 11 kW on a 3-phase connection
  • Charging speed drops significantly above 60% state of charge
  • Session starts at low power and never ramps up to full speed
  • Charger screen shows a lower power output than the unit's rated capacity

What to Do

  1. 1

    Check the battery temperature

    Look at the charging information on the 12.3-inch touchscreen. If the battery is cold, use the preconditioning feature in the Bluelink app before arriving at the charger. Driving for 15-20 minutes also warms the battery naturally.

  2. 2

    Check your state of charge

    If you are above 70%, the slowdown is expected on the Kona Electric. For road trip charging, plan to arrive between 10-20% and unplug at 80% for the best time-to-range ratio.

  3. 3

    Check the charger's rated output

    Look at the charger's specs on its screen, on the unit label, or in the charging network's app. If it is a 50 kW charger, the Kona Electric is getting what the charger can deliver. Find a higher-powered CCS2 charger for faster sessions.

  4. 4

    Check scheduled charging and charge limits

    On the infotainment screen or in the Bluelink app, make sure scheduled charging is not delaying or limiting the session. Check that the charge current limit is set to maximum.

  5. 5

    Check if the charger is sharing power

    Look at the charger cabinet. If two cables come from the same unit and someone is charging on the other cable, you may be splitting power. Move to an unoccupied charger if available.

  6. 6

    Try a different charger or station

    If speed is still low after checking everything, the charger may be underperforming. Try another stall or a different station entirely.

Common Tesla Supercharger Issues

Non-Tesla vehicle cannot find the station in the Tesla app

You arrive at a Supercharger with your non-Tesla EV but the station does not appear in the Tesla app, or it shows as Tesla-only.

Symptoms

  • Tesla app shows the station but does not list it as open to other brands
  • Station appears on the map but the 'Start Charging' button is grayed out
  • App says 'This location is not available for your vehicle'
  • You can see other non-Tesla vehicles charging but the app will not let you start

How to Fix It

  1. 1

    Confirm the station is open to non-Tesla vehicles

    Not all Supercharger locations are open to other brands. In the Tesla app, look for stations marked with a label indicating non-Tesla access. If there is no such label, the station is Tesla-only.

  2. 2

    Update the Tesla app

    Tesla frequently adds new non-Tesla locations. If your app is outdated, recently opened stations may not appear as accessible. Update to the latest version.

  3. 3

    Check your Tesla account setup

    You need a Tesla account with a valid payment method added, even if you do not own a Tesla. Open the app, go to your account settings, and confirm a credit or debit card is saved.

  4. 4

    Try selecting the specific stall number

    After plugging in, open the Tesla app, select the station, and tap the stall number that matches the one you plugged into. The stall number is printed on the charger post.

  5. 5

    Restart the Tesla app

    Force-close and reopen the app. Location and station data sometimes fails to load correctly on the first attempt.

Payment hold is larger than expected

Tesla places a pre-authorization hold on your payment method when you start a Supercharger session. This hold can be surprisingly large and may temporarily reduce your available balance.

Symptoms

  • Bank notification shows a hold of 50 to 120 EUR before charging begins
  • Available balance on your debit card drops significantly
  • Multiple holds appear from previous sessions that have not been released yet
  • Hold amount does not match the actual charging cost

How to Fix It

  1. 1

    Understand that holds are temporary

    Tesla pre-authorizes a fixed amount to ensure payment. The actual charge replaces the hold once the session is complete. The hold typically releases within 1 to 5 business days depending on your bank.

  2. 2

    Use a credit card instead of a debit card

    Credit cards handle pre-authorization holds without affecting your available cash balance. Debit cards temporarily lock the held amount from your account.

  3. 3

    Check the Tesla app for final session cost

    After charging, the Tesla app shows the actual amount you will be billed. This is always less than or equal to the pre-authorization hold.

  4. 4

    Contact your bank if holds persist beyond 7 days

    If a hold has not been released after a week, contact your bank and provide the transaction reference from the Tesla app. Banks can manually release stale holds.

Session ends early or stops unexpectedly

Charging stops before reaching your target battery level. The car disconnects or the Supercharger stops delivering power mid-session.

Symptoms

  • Charging stops at 80% even though you set a higher limit
  • Session ends after a few minutes with no error message
  • Car shows 'Charging interrupted' or 'Check charge cable'
  • Supercharger light turns from green to red or flashing

How to Fix It

  1. 1

    Check your charge limit setting

    Tesla vehicles default to an 80% charge limit. Non-Tesla vehicles have their own limit settings in the infotainment system. Verify you have set the limit above where charging stopped.

  2. 2

    Reseat the cable connector

    Unplug the cable, inspect the connector and your vehicle's charge port for debris, and plug it back in firmly. A loose connection can cause the session to drop.

  3. 3

    Try a different stall

    Individual Supercharger stalls can have intermittent faults. Move to another stall, preferably one that is not paired with an active session (stalls sharing a power cabinet are usually labeled with paired numbers like 1A/1B).

  4. 4

    Check for idle fees

    If you reached your charge limit and did not unplug promptly, Tesla may have ended the session and started idle fees. Check the Tesla app for notifications.

  5. 5

    Restart your vehicle

    For non-Tesla vehicles, turn the car off completely, wait 30 seconds, and turn it back on. Then plug in again. Some vehicles need a restart to clear communication errors with the Supercharger.

Reduced charging speed due to power sharing

Your charging speed is significantly lower than the station's advertised maximum. This often happens because Supercharger stalls share power with a paired stall.

Symptoms

  • Charging at 60 to 80 kW at a station rated for 250 kW
  • Speed dropped when another vehicle plugged in at a nearby stall
  • Speed is much lower than you got at the same station previously
  • One stall charges fast while the paired stall is very slow

How to Fix It

  1. 1

    Move to an unpaired stall

    Tesla Supercharger stalls are paired (for example, 1A and 1B share a power cabinet). If someone is using 1A, stall 1B will be slower. Choose a stall where neither paired unit is occupied.

  2. 2

    Look at the stall labels

    Paired stalls usually share a number with A/B suffixes, or are directly adjacent. At V3 Superchargers (250 kW), power sharing is less of an issue than at older V2 stations (150 kW).

  3. 3

    Check your battery temperature

    Tesla vehicles precondition the battery automatically when navigating to a Supercharger. If you did not use Tesla navigation (or you drive a non-Tesla), the battery may be cold and limiting charge speed on its own.

  4. 4

    Arrive with a lower state of charge

    Charging speed decreases as the battery fills. For the fastest stop, arrive between 5 and 20% if you can do so safely. The difference in charge speed between arriving at 10% versus 40% is significant.

Non-Tesla vehicle CCS2 connector issues

At Supercharger stations open to non-Tesla vehicles, the CCS2 connector may not work correctly with your car. In Europe, open Supercharger stations have native CCS2 cables, so no adapter is needed.

Symptoms

  • The CCS2 connector does not lock into your vehicle's charge port
  • Session starts but drops after a few seconds
  • Tesla app does not recognize your vehicle after plugging in
  • The connector fits but no power is delivered

How to Fix It

  1. 1

    Make sure you are using the CCS2 cable, not the Tesla connector

    Open Supercharger stations in Europe have separate CCS2 cables alongside Tesla connectors, or dedicated CCS2 posts. Use the CCS2 cable for non-Tesla vehicles.

  2. 2

    Push the connector in firmly until it clicks

    CCS2 connectors need a firm push to fully seat and lock. If the connector is loose, the charger cannot communicate with your vehicle.

  3. 3

    Start the session through the Tesla app

    Select the correct stall number in the Tesla app and start the session. The stall number is printed on the charger post. It must match exactly.

  4. 4

    Try a different stall

    Individual stalls can have faulty connectors. Move to another stall, preferably one that is not paired with an active session.

  5. 5

    Check vehicle compatibility

    Not all non-Tesla vehicles work perfectly at every Supercharger station. If your vehicle repeatedly fails to connect, check Tesla's website or app for your vehicle's compatibility status.

Tesla Supercharger App Tips

  • Non-Tesla drivers can use the Tesla app to start charging. At newer V4 Supercharger stations, contactless card payment is also available directly at the charger.
  • Use the Tesla app's map filter to show only stations open to non-Tesla vehicles. This saves you from driving to a Tesla-only location.
  • Start your session through the app by selecting the stall number printed on the charger post. The stall number must match exactly or the session will not start.
  • Enable notifications in the Tesla app. You will be alerted when charging is complete, if the session is interrupted, or if idle fees are about to start.
  • Check session history in the Tesla app under 'Charging.' You can see energy delivered, cost, and duration for every past session.

Payment Tips

  • At older Supercharger stations, the Tesla app is the only payment method. Newer V4 stations also accept contactless card payments. No RFID or roaming apps are supported.
  • Non-Tesla vehicles typically pay a higher per-kWh rate than Tesla vehicles at Superchargers. Check the rate in the Tesla app before starting.
  • Pre-authorization holds can be 50 to 120 EUR. Use a credit card to avoid temporarily losing access to cash in your bank account.
  • Idle fees apply if you remain plugged in after charging completes and the station is busy. The fee per minute is shown in the app. Unplug promptly to avoid charges.
  • Tesla Supercharger pricing varies by location and time of day. Some stations have peak and off-peak rates. The current rate is displayed in the app before you start.
