EV Charger Offline Behavior

Offline charger behavior and manual charging activation.

Updated this week

Emporia EV Chargers are designed to maintain charging capability even when WiFi connectivity is lost. This guide covers how your charger operates during offline scenarios, including manual activation, scheduling, and data logging.


Does the EV Charger Require Wi-Fi?

No, the charger functions at default settings (40A for NEMA 14-50, 48A for hardwired) without Wi-Fi. However, adjusting charge rates or enabling automated features requires an initial setup via the Emporia app. The charger will retain essential settings, such as breaker size or guaranteed charging rate, even after losing Wi-Fi connectivity.


Manual Charging Activation

If your charger is in the Ready state and not connected to Wi-Fi, you won't have any issues charging normally. Manual activation is only needed when your charger is in the Off state and offline, as this plug-in/plug-out process changes the charger's status when not connected to Wi-Fi.

When manual activation is needed:

  • Your charger is offline and in the Off state

  • The app cannot change the charger status due to no Wi-Fi connectivity

Step-by-step manual activation:

  1. Plug the charging handle into your vehicle for 2+ seconds, then unplug

  2. Repeat — plug in for 2+ seconds, then unplug again

  3. Plug in a third time and leave connected — charging will begin automatically

Alternative: Plugging in the charger twice while offline turns it on until a scheduled off event occurs.

This manual sequence bypasses all app controls and works with both plug-in and hardwired installations.


Scheduled Charging While Offline

Pre-set schedules remain active during Wi-Fi outages, but schedule updates require an internet connection. The charger will continue to follow previously downloaded scheduling rules until connectivity is restored.


Data Logging During Outages

  • Short outages (<20 minutes): Data is stored locally and uploaded once the connection is restored

  • Long outages (>20 minutes): The charger tracks cumulative energy usage and averages the data into records once reconnected. While total energy consumption remains accurate, individual time-based records may be estimated. In rare cases, the charger may lose track of cumulative usage, potentially resulting in data loss
