How to Fix / Troubleshooting
Note: Metering faults affect billing and reporting accuracy but may not always stop charging, depending on configuration.
- Check app readings: Compare the EVBox energy readings with the household meter or another reference to confirm inaccuracy.
- Power cycle: Turn the charger off for 1 minute and back on to reset the meter module.
- Inspect connections (qualified): With power off, open the unit and locate the internal meter module (often a small PCB or DIN‑rail device). Ensure its communication cable to the main board is firmly connected.
- Firmware check: Update firmware if a known metering bug is documented by EVBox.
- Replace meter module: If E017 persists and readings are clearly wrong, replace the internal meter module and re‑calibrate if required by EVBox procedures.
