Prerequisites

Project information

Before scheduling the commissioning of the EV infrastructure, evaluate with the facility manager of the building the impact of the commissioning regarding the building activities:

• Consider whether the building is occupied or not by residents, employees, or customers during the operation.

• Consider whether there is any specific safety plan to consider.

• Check that the power is on, tested, and running on site.

• Check that the access to electrical switchboards of the site and to the EV infrastructure is approved.

• Check that the IT manager and/or technical team are available.

• Check that there is 4G connectivity available in the technical room or from the EV switchboard where EcoStruxure EV Charging Expert is installed.

Electrical environment information

Before going on site, get the electrical distribution plan and wiring diagram of the site with all information regarding:

• Power supply

• Earthing system

• Electrical protections

• Number, location and details of main and subsidiary switchboards dedicated to the EV Supply Equipment (EVSE)

• Overall power allocated to the EVSE

• Installed or to be installed power meters (number, monitoring zone, model, location, IP address)

IT plan and network information

Check the following information with the IT manager:

• IP address range

• DHCP server available on site or not

• 4G modem available on site with remote access allowed

• Outcome: local IT is specified

• Detailed wiring diagrams and typology of the EV infrastructure network

• IP address, mask, gateway

• Domain Name System (DNS)

• 4G modem settings and SIM card ready

EV charging infrastructure information

Establish the composition of the infrastructure:

• Power range and model of charging stations

• For each charging station: name, location, serial number, phase wiring, derating, OCPP box ID

• Definition of the EV zones

• Supervision system (local or remote)

Usage and user information

Gather all relevant specifications you need to commission and configure EcoStruxure EV Charging Expert:

• Device location

• Load management system (LMS) mode (static or dynamic)

• Power meter models with ID and configuration settings if needed

• Maximum current

• Degraded mode (load shedding duration and priority: IEC or EV/ZE ready)

• Time of use

• Digital inputs

• Authentication patterns: free, via RFID (list of badges available, RFID tags known and ready), VIP and offline strategy

Other useful information

Before scheduling the commissioning of the EV infrastructure:

• Create a list of stakeholder contacts.

• Prepare all relevant product documentation (user manual, installation guide, commissioning guide).

• Check that all products are updated to their latest firmware version (charging stations, load management system, modem, switch).

• For EVlink Pro AC and Schneider Charge Pro charging stations, check that you have the latest version of eSetup application installed on your mobile phone.

• The SIM card is needed for wireless installation. Not all charging stations have embedded modem where you can insert a SIM card. Depending on the network architecture, the 4G modem can refer to an external modem or router (4G cellular modem). Before going on site, install all embedded or external SIM cards.
