Managing Authentication

When there is no charging station management system to manage authentication and grant access to the charging stations, EcoStruxure EV Charging Expert can handle access through the creation of groups and the use of RFID cards.

An authentication group is a selection of charging stations associated with a list of RFID cards. Each authentication group has its own online and offline authentication strategies.

Each charging station can only be associated with one authentication group. RFID cards can be assigned to several authentication groups.

To manage authentication strategy:

1. Select the Authentication menu.

   

2. Select one of the three following options for Authentication groups:

   • One global group: all installed charging stations are assigned to one authentication group.

   • One group per charger: one authentication group is created for each charging station (recommended solution to manage one RFID badge for one charging station).

   • Custom installation: create one or multiple authentication groups according to installation needs.

   NOTE: After configuration, you can change the authentication configuration from the ADMIN menu.

3. Define online and offline authentication strategies. The Offline strategy manages the authentication process when the charging stations are disconnected from EcoStruxure EV Charging Expert.

   

4. When selecting Save and Next, the following screen is displayed:

   

   1. Add an RFID card: to add or import RFID badges.

   2. VIP: tick this box to give the EV driver priority in load management system. This option is disabled by default.

   3. Authorized: tick this box to authorize the EV driver to start a transaction with this RFID card. This option is only used for assigned authentication group with Authorize only the known RFID cards authentication strategy. This option is disabled by default.

   4. Comments: to add a comment on an RFID card.

   5. Authentication group: to assign an RFID card to one or more authentication groups.

The list of RFID cards can be exported to a web interface or imported from a web interface. For information about csv format, see DOCA0358EN EcoStruxure EV Charging Expert User Guide.
