Vestel Wallbox Firmware Update _top_ -

To update the firmware on a Vestel Wallbox (specifically the EVC04 series), you can use the Web User Interface (Web UI) for manual updates or wait for Over-the-Air (OTA) updates if your device is connected to the internet. 1. Manual Update via Web User Interface (Web UI)

Alternative Method: USB Firmware Update (For Offline or Failed Updates)

If your wallbox is in a garage without Wi-Fi, or if the OTA update fails repeatedly, Vestel supports USB manual flashing. vestel wallbox firmware update

  • Stable Internet Connection: Do not rely on mobile hotspot. Use a stable 2.4GHz Wi-Fi connection (Vestel wallboxes are sensitive to 5GHz channels).
  • Power Stability: Ensure your home’s electrical supply is stable. Do not perform the update during a thunderstorm or when grid voltage fluctuates.
  • No Active Charging: Disconnect any EV from the wallbox. The update process will interrupt the charging relay.
  • Charge Phone/Tablet: The update might take 10–20 minutes. Keep the device running the app above 50% battery.
  • Record Current Settings: Take screenshots of your load balancing, schedules, and RFID user list. Rarely, updates reset configurations.

⚠️ Critical Prerequisites

  1. Do not unplug the car: Ensure no vehicle is charging during the update.
  2. Stable Connection: If updating via Wi-Fi, ensure the signal is strong. If updating via USB, do not remove the drive until finished.
  3. Correct File: Installing firmware meant for a different hardware revision (e.g., loading EVC04 firmware on an EVC11) can "brick" the device. Check your serial number sticker before downloading.

5. Compliance with Grid Regulations

In regions like Germany, the UK, and the Netherlands, grid operators require wallboxes to support specific reactive power control or frequency-based shutdowns. Regulatory updates are delivered via firmware. To update the firmware on a Vestel Wallbox
