Reminder to data providers: NCR designed as device-level dataset

This item is a gentle reminder to data providers that the NCR is a device-level, rather than location-level, dataset.

Since its inception, the NCR has been designed to be a device-based dataset with each record representing a single device with one or more connectors. Where several devices are at a single location, each device should be added as a separate record.

A number of key benefits follow from maintaining a device-level registry: First, manual and automatic status updates can more easily be linked to particular devices and connectors; second, this ensures the NCR data structure is in line with the Open Charge Point Protocol (OCPP) which is based on the Electric Vehicle Supply Equipment (EVSE) protocol; and third, the NCR is future-proofed should it become fully automated and dynamic.

Recent analysis revealed that 53 records included more than four connectors, with four records (representing devices at multi-story car park) having 30 or more connectors. To bring these records into line with a device-based structure, these records have been split into an appropriate number of device records sharing the same location and access details.

In the current system, data providers are able to add up to 80 connectors to each device record. While the NCR Admin will monitor new devices being input to the system, the maximum number of connectors per devices will be limited to four in November 2015 to reflect the fact that the vast majority of charge devices on the current market have no more than four connectors.

In the meantime, data providers are requested to review their current devices entries and data entry protocols.

If you have any queries regarding this planned change to the maximum number of connectors per device, please contact the NCR by tweet @ncrdata, phone 0300 777 0001. or email [email protected].
