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 150 kW Level 3 DC fast chargers. Unlike any switchgear of its kind, the NexPhase™ Smart EV Switchgear features cutting-edge grid intelligence and EV charger remote monitoring and control.

AN INTELLIGENT, TURNKEY SOLUTION

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.

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.

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.

READY-TO-INSTALL SWITCHGEAR

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.
