Wi-Fi and Connectivity Issues With EV Chargers
Most connectivity issues are related to signal strength or network settings rather than the charger itself.
Many modern EV chargers rely on a Wi-Fi connection to enable features such as scheduling, monitoring, and app control. When connectivity issues occur, they are usually caused by network coverage or configuration, not a fault with the charger.
A common issue is weak Wi-Fi signal at the charger’s location. Chargers installed outside or in garages can be at the edge of a home network’s range. If the signal is unstable, the charger may disconnect intermittently or fail to communicate with the app. In these cases, a Wi-Fi extender or mesh system often resolves the problem.
Another frequent cause is network compatibility. Many EV chargers require a 2.4GHz Wi-Fi network and will not connect reliably to 5GHz-only networks. If your router combines both bands, the charger may need to be reconnected during setup to ensure it joins the correct network.
Temporary connectivity issues can also occur after router updates, password changes, or power cuts. Restarting the router and the charger often restores the connection.
It is also important to keep the charger’s firmware and mobile app up to date. Outdated software can cause communication issues even when the Wi-Fi signal is strong.
If connectivity problems persist after these checks, reconnecting the charger through the setup process usually resolves the issue. Ongoing issues may require a review of network settings or additional support.
