Importance of Connectivity for EV Chargers
All EV chargers deployed by ChargeLab and its partners require a reliable Internet connection to communicate with the software. Connectivity can be established via:
- Cellular networks (3G/4G).
- Wi-Fi.
- Ethernet.
As a backend software provider for thousands of EV charger deployments, we know that connectivity is the most common cause of issues.
Test Connectivity Before Installation
Before installing a charger, ensure the location meets these minimum requirements:
- 4G: Signal strength of −80 dBm or better.
- Wi-Fi: Signal strength of −67 dBm or better.
General Tips for Ensuring Strong Connectivity
-
Make Connectivity a Priority
- Poor connectivity can lead to issues like failed charging sessions or unreported utility data.
-
Leverage Primary and Backup Connectivity Modes
- Most EV chargers support multiple connectivity modes. For example:
- Primary: 4G, with Wi-Fi as backup.
- Primary: Wi-Fi, with Ethernet as backup.
- While this setup increases costs, it’s critical for public or fleet charging infrastructure.
- Most EV chargers support multiple connectivity modes. For example:
-
Communicate with Your Installer
- Installing Wi-Fi mesh networks or testing 4G connectivity may not be within the expertise of electricians.
- Work with specialists in commercial building connectivity (Wi-Fi, security cameras, smart building technologies).
-
Prepare a Plan for Connectivity Issues
- Configure your platform to send automatic alerts when chargers go offline.
- Decide in advance:
- Who will handle issues (facilities manager, installer, connectivity expert).
- The process for resolving connectivity problems.
-
Enable Offline Redundancy
- Configure chargers to:
- Allow free charging when offline.
- Support RFID card charging for authorized users (billed when back online).
- Order and distribute RFID cards to users as needed.
- Configure chargers to:
