NexPhase - Smart EV Switchgear

As a result of the National Electric Vehicle Infrastructure (NEVI) Formula Program that provides funding for strategically deploying electric vehicle charging infrastructure along major US highways, many utilities are looking to incorporate EV chargers into their existing sites. NexPhase™ is an all-in-one, NEVI-focused intelligent switchgear solution that enables site owners to maintain higher charger uptimes while minimizing installation, maintenance, and operating costs.

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.

A switchgear is a critical component of a DC fast charger station`s infrastructure. Tasked with receiving, distributing, and protecting the site’s power, switchgear is typically composed of a series of electrical panels. Traditionally, these post-and-frame switchgear systems have been comprised of multiple mixed-manufacturer electrical panels that are wired together on-site during installation. NexPhase™ is a Buy America Compliant Component that provides an integrated, single cabinet, ready-to-install solution to minimize the complexity and effort required to install a switchgear that fulfills NEVI requirements.

SINGLE ENCLOSURE
NexPhase™ combines a Current Transformer (CT) cabinet, 480 VAC 3-Phase breaker panel, 240/120 VAC single phase breaker panel, and transformer into a single enclosure.

RAPID DEPLOYMENT
Eliminate the additional resources, time, and supply chain difficulties often associated with designing and sourcing a mixed-manufacturer post-and-frame switchgear systems.

ACCELERATE ROLL OUT
All internal components come pre-installed and pre-wired. With a shortage of qualified, veteran electricians available, NexPhase™ makes it easy to execute more EV charger projects with existing workforces.

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.

• 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.
