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 varies depending on your vehicle, environmental conditions, and various settings. Here's how to troubleshoot: This guide will also help you understand how to track your energy usage effectively using tools like the Emporia app.
1. Check Vehicle Limitations
Verify your vehicle's maximum Level 2 AC charging rate
Note that some cars have different "home" versus "public" charging behaviors
Not sure what your EV chargers are at, check out Green Cars Compare and use the charging calculator to verify.
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)
Use the Emporia app to track energy usage and view charging history, helping to monitor and optimize performance.
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
Check for any AC charging limits in the vehicle's charging settings.
Please note that public DC fast chargers typically offer higher power rates compared to home-based AC chargers, as this depends on your vehicle's onboard system.
4. Consider Environmental Factors
Battery temperature affects charging rate (too hot/cold reduces rate)
Nearly complete batteries automatically charge more slowly to protect battery life
Test charging rate when the 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
7. Track Energy Usage
Viewing Individual Charging Sessions
Navigate to the home screen in the Emporia app.
Steps: Tap on your EV Charger → Select
History.You'll see a calendar with daily energy usage figures. Switching to the
Sessionsview provides detailed metrics for individual charging sessions, helping you understand energy patterns.
Incorporating Charger Data with Vue Energy Monitor
If your EV charger shares an installation panel with a Vue Energy Monitor, the app aggregates that data into the total energy usage value.
To separate or nest your charger under the monitor for accurate reporting:
In the app: Home Screen → Tap EV Charger → Select
Charger Settings→ OpenEV Charger Info→ Proceed toNest Under.Choose your
Energy Monitorchanges and save.
These steps enable precise tracking of charger energy consumption, offering better insights into usage patterns.
