Why Texzon Utilities for EV Infrastructure?

Consumers, businesses, and fleets considering electric vehicles (EVs)—which include all-electric vehicles and plug-in hybrid electric vehicles (PHEVs)—need access to charging stations. Texzon charging stations at workplaces and public destinations may help bolster market acceptance by offering more flexible charging opportunities at commonly visited locations. Community leaders can find out more through EV readiness planning, including case studies of ongoing successes. The EVI-Pro Lite tool is also available to estimate the quantity and type of charging infrastructure necessary to support regional adoption of EVs by state or city/urban area and to determine how EV charging will impact electricity demand.​

Charging Infrastructure Terminology

The charging infrastructure industry has aligned with a common standard called the Open Charge Point Interface (OCPI) protocol with this hierarchy for charging stations: location, EV charging port, and connector. The Alternative Fuels Data Center and the Station Locator use the following charging infrastructure definitions:

Station Locations

 

A station location is a site with one or more EV charging ports at the same address. Examples include a parking garage or a mall parking lot.​

EV Charging Port

 

An EV charging port provides power to charge only one vehicle at a time even though it may have multiple connectors. The unit that houses EV charging ports is sometimes called a charging post, which can have one or more EV charging ports. EV charging ports are also sometimes referred to as electric vehicle supply equipment (EVSE) ports.


Connector

 

A connector is what is plugged into a vehicle to charge it. Multiple connectors and connector types (such as CHAdeMO and CCS) can be available on one EV charging port, but only one vehicle will charge at a time. Connectors are sometimes called plugs.​​

Charging equipment for EVs is classified by the rate at which the batteries are charged. Charging times vary based on how depleted the battery is (i.e., state-of-charge), how much energy it holds (i.e., capacity), the type of battery, the vehicle's internal charger capacity, and the type of charging equipment (e.g., charging level, charger power output, and electrical service specifications). The charging time can range from less than 20 minutes using DC fast chargers to 20 hours or more using Level 1 chargers, depending on these and other factors. When choosing equipment for a specific application, many factors, such as networking, payment capabilities, and operations and maintenance should be considered.​

AC Level 2 equipment (often referred to simply as Level 2) offers charging through 240 V (typical in residential applications) or 208 V (typical in commercial applications) electrical service. Level 2 equipment is also commonly used for public, and workplace charging and can operate at 40 to 80 amperes (Amp). Most residential Level 2 chargers operate at up to 30 Amps, delivering 7.2 kW of power. These units require a dedicated 40-Amp circuit to comply with the National Electric Code requirements in Article 625. 

Level 2 charging equipment uses the same J1772 connector that Level 1 equipment uses. All commercially available EVs in the United States have the ability to charge using Level 1 and Level 2 charging equipment.

Vehicles with a J3400 (also referred to as NACS, or North American Charging Standard) connector (currently only Tesla vehicles) can use the connector for all charging levels, including Tesla's Level 2 Destination Chargers and chargers for home. All Tesla vehicles come with a J1772 adapter, which allows them to use non-Tesla Level 2 charging equipment.

† A Level 2 unit can range from 2.9 to 19.2 kW power output.

Direct Current DC fast charging equipment (typically a three-phase AC input) enables rapid charging along heavy traffic corridors at installed stations. The availability of DC fast charging is expected to increase as a result of federal funding to build a national EV charging network, such as the National Electric Vehicle Infrastructure Formula Program or national Alternative Fuel Corridors grant program. Additionally, DC fast charging is projected to increase due to fleets adopting medium- and heavy-duty EVs (e.g., commercial trucks and vans and transit), as well as the installation of fast charging hubs for transportation network.

There are three types of DC fast charging systems, depending on the type of charge port on the vehicle: SAE Combined Charging System (CCS), CHAdeMO, and J3400.

 

The CCS connector (also known as SAE J1772 combo) lets drivers use the same charge port with AC Level 1, Level 2, and DC fast charging equipment. The only difference is that the DC fast charging connector has two additional bottom pins. Most EV models on the market can charge using the CCS connector.

The CHAdeMO connector is another common DC fast connector type among Japanese automakers.

SAE International is standardizing the J3400 connector based on the design for the NACS connector, which works for all charging levels.​

High Efficiency Wide Band Gap Technology

SiC technology has a variety of positive attributes for EV charging and power inverter use cases relative to IGBT technology. Chief among these is the ability to switch at significantly higher frequencies than IGBT-based designs. SiC-based EV chargers and inverters are more efficient than the equivalent chargers and inverters based on IGBT technology. SiC efficiencies can be as high as 98%, compared with typical IGBT efficiencies of 90%-95%.

The Rhombus 120/180 deliver the same power in a 28% smaller footprint and eliminates the need for external cooling systems that create more operations and maintenance costs and potentially environmentally harmful conditions.

Continuous Operation at Rated Loads

We apply our high-power electronics expertise to our unidirectional DC fast-charging solutions for commercial EV fleets such as school buses, public transit buses, delivery vehicles, refuse trucks and drayage tractors. Our EV charging solutions are designed specifically for continuous operation at rated loads.
