Blink EV charger displays E18 and may indicate a time-out or session control error.

Safety first: No internal work should be done live. Turn off power before opening the unit.

Steps to troubleshoot:

• Reboot charger: Power cycle at the breaker and attempt a new session.
• Check cable and connector: Ensure the J1772 handle seats firmly in the vehicle and that the latch engages fully. A loose connection can cause pilot interruptions.
• Network latency: For networked Blink chargers, verify that the internet connection is stable and not heavily congested.
• Firmware update: Apply any available firmware updates from Blink that address session stability.

If E18 continues across multiple vehicles and after firmware updates, the main control board may have a hardware fault in its timing or memory circuits and should be replaced.
