NEXPHASE™

Smart EV Switchgear

The NexPhase™ Smart EV Switchgear is an all-in-one switchgear enclosure containing the entire infrastructure required between the utility service and up to four Level 3 DC fast chargers. Unlike any switchgear of its kind, the NexPhase™ Smart EV Switchgear features cutting-edge grid intelligence for switchgear and EV charger remote monitoring and control.

Highlights

DESIGN SIMPLIFIED

ACCELERATE PROJECT TIMELINES

By combining all switchgear equipment into one enclosure, NexPhase™ eliminates the lengthy design process of traditional post-and-frame systems, which require additional costs to design and source a mixed-manufacturer panel system.

CONNECTION ENABLED

REMOTE MONITORING & CONTROL

An embedded monitoring system provides remote access to real-time health data with remote power cycling capabilities and automated alarms to facilitate condition-based maintenance planning.

CHARGER RESILIENCY

INCREASE EV CHARGER UPTIME

With early detection of EV charger deficiencies and system performance diagnostics provided by NexPhase™, fleet operators are provided with the tools to improve uptime, extend equipment service life, and enhance the reliability of their EV charger systems.

OUTAGE MITIGATION

PINPOINT OFF-LINE EV CHARGERS

It’s approximated that up to 25% of public U.S. EV chargers are out of operation at any given time, with these outages going undetected until a technician is physically present. NexPhase™ provides ongoing state-of-charge data so operators can identify outages and remotely cycle power to maintain the 97% uptime requirement set by the NEVI guidelines.

INSTALLATION MADE EASY

MITIGATE UP-FRONT COSTS

NexPhase™ only requires the on-site connections for the incoming power and outgoing charger connections, drastically reducing on-site installation time and costs.

SAFETY FEATURES

PROTECT YOUR SITE

NexPhase™ includes integrated emergency-stop capabilities for NFPA compliance and added safety features including EV charger crash detection and flammable gas monitoring with automatic shutdown and remote alerts.

APPLICATION

In support of the National Electric Vehicle Infrastructure (NEVI) Formula Program, NexPhase™ enables rapid deployment of the electric vehicle charging infrastructure by offering a turnkey switchgear solution that provides real-time monitoring and alerts, making it easier to achieve and provide evidence of the required 97% uptime.

TECHNOLOGY

Combines the Current Transformer (CT) cabinet, 480 V 3-Phase breaker panel, 240/120 V single phase breaker panel, and transformer into a single enclosure.

Integrated 250 A breakers (qty 4 - 1 for each EV charger) capable of supporting up to four 150 kW DC fast chargers.

Integrated communication via both Ethernet and Cellular connection for remote applications.

The on-board NexPhase Hub™ Power/Health Monitor provides power and switchgear monitoring with cloud-based access to data via a remote user interface.

Helps ensure charger uptime and facilitates predictive maintenance by providing remote access to key EV charger health indicators including incoming power measurements, charging state, and energy usage.

Provides ongoing EV charger state-of-charge data, enabling charger operators to accurately pinpoint EV charger outages and deploy maintenance only when and where it is needed. Many EV charger deficiencies may be solved with the remote power cycling capability.

NEXPHASE™ HUB POWER/HEALTH MONITOR

The NexPhase™ Hub is a power and health monitor which provides continuous, precision performance monitoring of switchgear power measurements and key state-of-health indicators. Components include:

Voltage Leads (Qty 5)
Split-Core Rogowski Coils (Qty 4)
Ethernet Cable
Status Indicator LED

UNITE™ WEB-BASED INTERFACE

An MQTTS Communication Protocol allows the NexPhase™ Hub to securely communicate with the web-based UNITE™ user interface. UNITE™ provides user-friendly access to monitoring information including:
