Smart EV Switchgear
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
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:
Power Analysis
- Current by Phase
- Power Factor by Phase
- Power Factor vs. Current
