Overview

1. Function Description
2. Usage Features
3. Maintenance Features

The FLO CoRe+™ is a Level 2 electric vehicle charging station designed for both residential and commercial applications. It offers a robust and user-friendly solution for charging electric vehicles, with various models available to suit different needs. The device is built for durability and outdoor use, featuring a 4X enclosure type, making it suitable for a wide range of environmental conditions.

Function Description

The primary function of the FLO CoRe+™ is to provide Level 2 charging for electric vehicles equipped with a SAE-J1772 connector. It converts AC power from the grid into a form suitable for charging an EV's battery. The charging station is designed to be either ground-based, wall-mounted, or post-mounted, offering flexibility in installation.

The CoRe+™ series includes different models:

• CoRe+V2: This model is equipped with a display and a card reader, allowing for user interaction and authentication.
• CoRe+VBV2: This is a more basic model without a display or a card reader, suitable for private or simpler installations where user authentication isn't required at the station itself.
• CoRe+PSV2: This model features a display, a card reader, and PowerSharing™ firmware. It is designed for dynamic current sharing in installations with multiple charging stations on the same circuit, optimizing power distribution.

The charging station incorporates built-in protection against overvoltage conditions and leakage current to ground, ensuring safe operation. It requires a split-phase 120/240 VAC supply or a 3-phase 120/208 VAC supply, protected by a 40 A fuse or circuit breaker. The power supply must be grounded, and the connection requires two lines and one ground connection, with the neutral not being used.

For commercial applications, especially in California, the commissioning process might require an authorized Division of Measurement Standards (DMS) agent if the station is intended for energy billing.

Usage Features

The FLO CoRe+™ offers several features that enhance its usability:

• User Interface (CoRe+V2 and CoRe+PSV2): These models include a display that shows greeting messages and status information. A card reader allows for user authentication using an access card.
• PowerSharing™ (CoRe+PSV2): This advanced feature allows up to four CoRe+PS charging stations to be connected in parallel to the same branch circuit. A site controller, provided by FLO as part of its central management service, dynamically shares the available maximum current among the charging stations. This ensures optimal power distribution (between 8 A and 30 A per station) while preventing the circuit capacity (32 A for a 40 A breaker) from being exceeded. If an EV draws more than the amperage limit, the charging session is immediately interrupted for safety, requiring the user to restart the session. Communication between the site controller and charging stations is facilitated via a wireless meshed Zigbee network.
• Status Indicators: Upon applying power, the status light continuously glows green, indicating readiness. After a successful preliminary test, the overhead status light will flash white.
• Authentication and Automated Testing: When an access card is scanned on models with a card reader, the device emits an audible sound, authenticates the card, and then performs an automated test of the protection circuit.
• Charging Process: If the card authentication and protection circuit test are successful, and a connector is inserted into an EV, charging begins. If no EV is connected after one minute, the station transitions to waiting mode.
• Connectivity: The CoRe+V2 and CoRe+PSV2 models support ONP and OCPP communication protocols, allowing them to be connected to FLO's management system via a communication gateway.

Maintenance Features

The design of the FLO CoRe+™ emphasizes ease of installation and maintenance, with clear guidelines to ensure longevity and safe operation:

• Installation Guide: The manual provides detailed instructions for installation, including wall or post mounting, with options for power cable entry from under the station or from the back, and installation with an electrical box.
• Component Access: The housing can be opened to access internal components for wiring and maintenance. The guide specifies how to connect power conductors (L1, L2) and the ground conductor (GND) to the terminal block.
• Cable Management: Instructions are provided for installing cable connectors and ensuring conductors are long enough to reach the terminal block.
• Protection Plate: The manual highlights the importance of never removing the protection plate of the keyhole, which is crucial for maintaining the device's integrity.
• Sealing: When closing the housing, it is essential to ensure that the seals remain in place and to install an O-ring to the upper screw for proper sealing.
• Safety Precautions: The manual stresses the use of a manual screwdriver only, avoiding impact drivers to prevent voiding the warranty. It also advises wearing safety glasses and gloves when handling parts due to potentially sharp edges.
• Communication Gateway: The communication gateway, owned by AddÉnergie, should be installed prior to commissioning. An outdoor installation is recommended, with the customer providing a waterproof PVC box less than 50 meters (164 ft.) from the stations. It's explicitly stated never to use a GFCI outlet to power the communication gateway. FLO services can be contacted to validate signal levels and activate commissioning.
• Warranty: Any alteration to the EVSE parts will automatically void the warranty.
• Pre-assembly for Cascading: For cascading installations (40 A or 150 A circuits), the manual details the pre-assembly of mounting brackets, terminal blocks, and circuit breakers, ensuring proper setup for multi-station configurations.
• Power Supply Disconnection: It is crucial to always disconnect the power supply of the EVSE before servicing to ensure safety.
