How to set connectivity up for success

 

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

  1. Make Connectivity a Priority

    • Poor connectivity can lead to issues like failed charging sessions or unreported utility data.
  2. 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.
  3. 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).
  4. 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.
  5. 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.
