If your electric vehicle isn't charging at the expected rate, this doesn't necessarily indicate a problem with your Emporia EV Charger. The charging rate depends on your vehicle, environment, and various settings. Here's how to troubleshoot:
1. Check Vehicle Limitations
Verify your vehicle's maximum Level 2 AC charging rate
Note that some vehicles have different "home" versus "public" charging behaviors
2. Review App Settings
Confirm that the real-time charge rate is set appropriately in the Emporia Energy app
Verify that no energy management features are limiting charging (scheduled charging, Peak Demand, Excess Solar, PowerSmart settings, utility demand programs)
Ensure maximum amperage matches your installation (40A for NEMA 14-50 outlet, 48A for hardwired)
3. Adjust Vehicle Settings
Check vehicle settings to allow maximum charge rate
Confirm if "home" and "public" charging rates differ in your vehicle's settings
4. Consider Environmental Factors
Battery temperature affects charging rate (too hot/cold reduces rate)
Nearly full batteries automatically charge slower to protect battery life
Test charging rate when battery level is lower
5. Inspect Installation
Verify proper installation and electrical connections
6. Test Compatibility
Try another Level 2 AC charger with your vehicle
Test the Emporia EV Charger with another vehicle if possible
