Petit Monde Energy

Charger Onboarding Guide

Step-by-step instructions to connect your charging station to the Petit Monde Energy platform

Prerequisites

Before you begin, ensure you have:

Physical access to the charging station
Admin credentials for the charger's configuration interface
Network connectivity (Ethernet, WiFi, or 4G/5G SIM card installed)
Your station registered in EV Suite (see "Add Station" button on Stations page)

Step 1
Network Configuration

Ethernet / WiFi:

  • • Ensure DHCP is enabled, or configure a static IP
  • • Verify internet connectivity (ping 8.8.8.8)
  • • Ensure ports 443 (HTTPS) and 80 (HTTP) are accessible

Cellular (4G/5G):

  • • Insert activated SIM card into charger
  • • Configure APN settings (provided by your mobile operator)
  • • Verify signal strength (minimum 2 bars recommended)
  • • Record ICCID for documentation (found on SIM card or in charger menu)
Firewall Note: If behind a corporate firewall, ensure outbound WebSocket connections (WSS) on port 443 are allowed to control.petitmonde.energy

Step 2
OCPP Configuration

Configure the charger to connect to our OCPP backend

wss://control.petitmonde.energy/ocpp/[YOUR_CHARGE_POINT_ID]

Replace [YOUR_CHARGE_POINT_ID] with the Charge Point ID you registered in Step 0

OCPP 1.6J

JSON over WebSocket

WebSocket Secure (WSS)

Encrypted connection

Security & Authentication

HTTP Basic Auth

Contact your administrator for credentials
Valid Let's Encrypt certificate installed - no manual configuration needed

Manufacturer-Specific Configuration

ABB: Navigate to Settings → Communication → OCPP → Central System URL
Alfen: Go to Configuration → Backend → URL and select OCPP 1.6 JSON
Delta: Access Web UI → Network → OCPP Backend Configuration
Generic: Look for "Backend URL", "Central System", or "CSMS URL" in your charger's settings

Step 3
Test & Verify Connection

Save Configuration & Reboot

  1. Save all OCPP configuration changes in the charger
  2. Reboot the charging station (soft reset recommended)
  3. Wait 30-60 seconds for the charger to establish connection

Verify in EV Suite Dashboard

1.Go to the Stations page
2.Find your station by Charge Point ID
3.Check that the status shows
Online
4.Verify "Last Heartbeat" timestamp is recent (within last minute)

Success Indicators

  • Status shows "Online" or "Available"
  • BootNotification accepted by server
  • Regular heartbeat messages every 60 seconds
  • Charger responds to remote commands (test with "Reset" if needed)

Troubleshooting

Charger shows "Offline"

  • • Verify network connectivity (check cable, WiFi signal, or cellular signal)
  • • Confirm OCPP URL is correct (check for typos, especially in Charge Point ID)
  • • Check firewall rules allow outbound connections on port 443
  • • Review charger logs for connection errors

Authentication failures

  • • Double-check Basic Auth credentials (username and password)
  • • Ensure no extra spaces in credentials
  • • Verify the Charge Point ID matches exactly what was registered in EV Suite
  • • Contact support if credentials were not provided

SSL/TLS errors

  • • Ensure charger supports TLS 1.2 or higher
  • • Update charger firmware if SSL handshake fails
  • • Some older chargers may require manual certificate installation (contact support)
