Possible Causes

Loose control wiring to contactor coil, Marginal pilot signal due to damaged cable, Overheating causing thermal cutback, Firmware bug causing session reset

How to Fix / Troubleshooting

Safety first: Intermittent faults can be heat‑related. If you notice excessive warmth on the enclosure, isolate power and allow it to cool.

  • Monitor pattern: Note whether interruptions occur at similar times (e.g., after 30–60 minutes) or at high current levels; this can indicate thermal issues.
  • Check cable and plug: Inspect the tethered cable or socket and plug for damage or excessive heat during charging. Replace any discolored or deformed components.
  • Inspect internal terminations: With power off, tighten all control and power terminals, especially those on the contactor and PCB.
  • Update firmware: Use the EO app to ensure the charger is running the latest firmware, which may address known intermittent issues.
  • Contact EO support: If the problem persists, log timestamps and conditions of failures and share them with EO support; a PCB or contactor replacement may be required.
