EV Charging Station
Introduction
The GE EV Charging Station offers Level II charging capable of reducing charge
time from 12-18 hours to 4-8 hours with service needs of 208-240VAC at 40A,
assuming a 24kWh battery and a full-cycle charge. GE recognizes that this is an
industry that will develop and change over time and, as a result, the EV Charging
Station is designed to accommodate future changes and technological advances.
The EV Charging Station is “future proof” through a modular design, giving the
owner the ability to upgrade the unit with field installable modules without
replacing the charging station.
GE has over 40 years of experience in the manufacture of RV pedestals, which
provides knowledge and familiarity for the manufacture of EV charging stations.
In addition, a crucial component to the implementation of EV charging stations
is the upstream infrastructure needed for installation. GE has over 100 years
of experience in the manufacture of electrical distribution systems. As a result,
we are able to offer a complete EV infrastructure solution that includes the
EV Charging Station and the associated upstream infrastructure.

Control Unit
The control unit will integrate SAE J1772 Functions, Metering, Overload monitoring and will manage HMI and all
local monitoring.
• The SAE J1772 functions include the following:
• Energization and De-energization of the system
• Verification of vehicle connection; the EVSE de-energizes output when the connector is uncoupled
• Continuous monitoring of ground connection between the EV and the EV Charging Station
• Automatic De-energization of the cable in case of rupture or separation of the cable
• Continuous monitoring of EVSE current capacity with supply rating recognition by PWM 1kHZ signal
• Determination of ventilation requirements depending on battery type of vehicle
The GE EV Charging Station provides communications through the controller prompting proper cord management.
A message on the VFD screen instructs the operator to return the plug to the EVSE inlet, thereby reducing the
possibility of plug and cord damage. The proximity detection feature, which is part of the SAE J1772 connector,
enables the coupler to communicate the presence of the connector when it is inserted into the EVSE coupler.
Overload monitoring is provided by the control unit which features protection above 125% nominal current. This
threshold limit will be below the breaker protecting the EVSE’s limit to avoid local maintenance of the system during an
overload event. The control unit will include a 15-20 mA ground fault protection according to UL2231. An integrated
single phase meter will measure current and voltage in addition to calculating energy and power. The control unit also
performs monitoring of the contactor to ensure the contactor is in the correct state when charging or not charging.
User Interface
The GE EV Charging Station offers a user interface that is easy to operate and guides a user through charging their
vehicle. A Vacuum Fluorescent Display (VFD) screen features greetings, instructions, and charging station messages
as well as featuring communications for the single phase metering. The LED light located at the top of the charging
station displays charger statuses as follows:
• Green = Station active
• Blinking green = Vehicle connected, not charging
• Amber = Charging
• Red = Fault occurred
Radio Frequency Identification
GE EV Charging Stations offer the option for Radio Frequency Identification (RFID). The ISO 15693 compliant RFID
can be used with key cards provided by GE. Users will simply wave their key cards in front of the RFID reader at
the particular EV Charging Station intended for use and will be authorized to start charging. There are a few
benefits associated with implementing RFID:
• Ethernet network offered for RFID authorization service
• Provides security, enabling only authorized users to operate the charging station through RFID
• Secure software application offering different privilege levels for owner/operator of the EV Charging Station
RFID Software Application
The RFID software application is responsible for maintaining and processing authorization of users for the EV Charging
Stations it supports. EVSE operators will be able to control adding, removing, or suspending user authorization. The
software application also supplies reports on the EVSE usage, enabling data collection, and monitors the status of
communication between the RFID software and EV Charging Station. This is a local desktop application which runs
on a Windows®operating system, requiring Windows XP or Windows 7. The software desktop application, which
stores data in a relational database, communicates with the EV Charging Station controller over TCP/IP protocol.

Upstream Infrastructure
As EV infrastructure extends beyond just the charging station, upstream electrical distribution equipment is critical
to ensuring a safe, reliable EV infrastructure system is built and maintained. Whether it is installing brand new
equipment or making upgrades to already existing infrastructure, GE has the domain expertise and channel partners
to perform the type of upgrades that may be required to support the use of EV Charging Stations. The following
information is a brief overview of upgrades in this space.
Spectra Series™ Switchboards
Spectra Series Switchboards offer a design that provides the high quality and reliability that has long been associated
with GE group-mounted switchboards. All GE switchboards can incorporate our full line of circuit breakers, power
management components, transient voltage suppressors and meters. Similar to our EV Charging Stations, the
Spectra Series Switchboards are designed and manufactured to meet GE internal standards along with NEMA,
NEC, UL and CSA requirements. In addition, Spectra RMS Circuit Breakers meet all applicable NEMA, NEC, UL and
CSA requirements, plus those for JIS and IEC.
Spectra Series™ Power Panelboards
GE Power Panelboard interiors are offered in two different styles: plug-in and bolt-on. Spectra Plug-In interiors are
designed for use with either fusible switches or molded case circuit breakers. A combination of the devices can be
used on a common interior. Spectra Bolt-On interiors are designed for use with circuit breakers only. Main or branch
devices (fusible switch or circuit breaker), as well as lugs only, can be installed at the factory or at the construction
site providing application flexibility. Unique to GE, the design approach makes field reconfiguration possible, as
well as having a universal platform that offers interchangeable boxes, fronts and interiors. All panelboards are
manufactured in accordance with UL standards 50 and 67 and conform to the latest requirements of the NEC and
NEMA standards.
A Series Panelboards
Our A-Series design is an extremely flexible Lighting Panel with over 12,000 combinations, most available within
a 10 day production cycle. NEMA 3R, 12 and 4x enclosures are all available options. The panel’s comprehensive
design and ease of installation are two reasons why contractors turn to this panelboard. All GE A Series panelboards
meet UL standards, as well as NEMA PB1, and NEC article 384.
General Purpose Transformers
GE has been building transformers for almost 100 years, but we continue to innovate and improve the reliable QL
design. GE Type QL transformers meet NEMA TP-1 efficiency standards. Available in aluminium and copper and in
all three temperature rise ratings, QL transformers utilize a UL recognized 220°C insulation system and are UL
listed. The transformers are 100% factory tested for shorts and coil integrity, current and loss, voltage, impedance
and noise.
