EV Charging Troubleshooting Guide ​

This page covers common EV charging issues and easy steps you can try before contacting support. It also includes simple explanations about charging speeds and how AC home chargers work.

⚡ Common Charging Issues & Quick Fixes ​

Charging Too Slow ​

  • Ensure the cable is firmly plugged into both the EV and the charger.
  • Check the TerraFuse app to confirm the session is active.
  • Charging naturally slows after 80% to protect the battery.
  • Your vehicle’s AC charging limit is the maximum speed you will get on any AC charger.
  • Try another charger if available to rule out hardware issues.

Cable Not Detected ​

  • Unplug and reconnect the cable on both ends.
  • Check for dust, dirt, or moisture in the charging port.
  • Ensure your car has unlocked the port (some EVs auto-lock it).
  • Restart your charging session in the app.
  • Try a different cable or charger to identify the cause.

🔄 Booking & Session Notes ​

Accidental Double Booking ​

If you accidentally make an extra booking, don’t worry —
It will automatically cancel after 15 minutes if no charging activity begins.

This helps keep chargers available for others and avoids unnecessary charges.

📘 Why Charging Speeds Can Vary ​

AC vs DC Charging ​

AC Charging (Apartment / Home Chargers)

  • Slower, steady, and safer for daily charging
  • Limited by your car’s onboard AC-to-DC converter
  • Gentler on the battery and electrical system
  • Typically ranges from 3.6 kW to 22 kW, but your car decides the actual speed

DC Fast Charging (Public Fast Chargers)

  • Very fast charging
  • Bypasses the onboard converter and sends DC power directly to the battery
  • Best for long trips, not for everyday home use

🔍 Example: Why Your Speed May Be Lower Than Expected ​

Even if an AC charger is rated for 22 kW, you might only get:

  • 7 kW, because that is the maximum AC speed your car supports, or
  • 11 kW, if your car has an 11 kW onboard converter

Your EV’s onboard converter acts like a “speed limit” for AC charging.

This is normal and depends on the model of your electric vehicle.

🕒 Expected Charging Time Example ​

If your car limits AC charging to 7 kW, then:

  • A 21 kWh battery would take about 3 hours
  • A 50 kWh battery would take around 7 hours
  • Topping up from 50% to 80% may take only 1 to 2 hours

These numbers vary by battery size and charging conditions.

🌙 Tip: Use Overnight Charging ​

Most EV owners prefer to charge after 10 PM, because:

  • Charging is safer when electrical load is lower
  • You don't need to wait—just plug in and sleep
  • It helps maintain good battery health with slower, steady charging
