What fields must be included in the CDR file?

Each row in the file should represent one session only (please don't split a single session across multiple rows). The required fields per session are:

• CDR ID / Roaming session ID - use the external session ID from the roaming protocol, not your internal CPO session ID
• EVSE ID
• Authentication ID / Contract ID
• Start time (DD/MM/YYYY HH:MM:SS)
• End time (DD/MM/YYYY HH:MM:SS)
• Consumption (kWh)
• Duration (minutes, as a whole number)
• Total net cost per session (2 decimal places)
• Currency

The total amounts in your CDR file must match the total on your invoice.
