Key EV Charging Industry Terms and Our Innovations

A

AC

Alternating Current (AC) is an electrical current that periodically changes direction, typically flowing back and forth in a sinusoidal wave pattern. In electric vehicles, the AC from the power grid is converted to Direct Current (DC) to charge the vehicle's battery.

Adapter

An adapter is a device that modifies one type of electrical input to another, often adjusting the plug shape or electrical output to suit the requirements of a particular device. For electric vehicles, adapters allow for charging at various types of charging stations by ensuring compatibility between the vehicle's charging port and the station's connector.

b

Battery Electric Vehicle (BEV)

A Battery Electric Vehicle (BEV) is a type of electric vehicle that runs entirely on electric power stored in a battery pack. BEVs do not have an internal combustion engine or use gasoline; instead, they rely solely on electricity, which is drawn from the battery to power an electric motor. The batteries are charged by plugging the vehicle into an electric power source. BEVs are known for producing zero tailpipe emissions, making them an environmentally friendly transportation option.

C

Combined Charging System (CCS)

The Combined Charging System (CCS) is a standardized charging system for electric vehicles that supports both AC and DC charging. It integrates the functionality of different charging methods into a single connector.

D

Direct Current (DC)

Direct Current (DC) is a type of electrical current that flows in one constant direction, unlike Alternating Current (AC) which periodically reverses direction. DC is characterized by a constant voltage, making it suitable for applications where stable and consistent power is required.

E

Electric Vehicle (EV)

An Electric Vehicle (EV) is a vehicle that runs on electric motors powered by rechargeable batteries, rather than internal combustion engines fueled by gasoline or diesel.

F

Fuel Cell Electric Vehicle (FCEV)

A Fuel Cell Electric Vehicle (FCEV) is a type of vehicle that uses hydrogen fuel cells to generate electricity, powering an electric motor for propulsion, with water vapor as the only emission.

G

Grid

The grid refers to the interconnected system of power lines and stations that transports electricity from producers (such as power plants or renewable energy sources) to consumers (homes, businesses). It plays a crucial role in supplying energy needed to charge electric vehicles efficiently and reliably.

H

Home charging

Home charging involves the process of recharging an electric vehicle at one's residence, typically overnight, using either a personal charging station or a standard electrical outlet.

I

ISO 15118

A global standard that establishes the communication protocol that enables plug-and-charge functionality between electric cars and charging stations.

J

J1772 Connector

A common connector used mostly for AC charging in North America for charging electric cars.

K

Kilowatt  (kW) 

A power measurement unit equivalent to one thousand watts that is used to assess engine output and EV motor power capacity.

L

Level 2

Faster than Level 1, it generates between 3.3 and 19.2 kW, depending on the electric car and the charger, and requires a 240-volt outlet (as major appliances like dryers use). The majority of EVs can be fully charged overnight thanks to L2, which can add between 12 and 80 miles of range every hour.

M

Miles per Kilowatt Hour (mpkWh)

A metric used to quantify the efficiency of electric vehicles that shows how far they can go on a single kWh of power.

N

North American Charging Standard (NACS)

The term NACS most likely refers to the charging connectors and protocols that are defined for North America, such as the Combined Charging System (CCS) and SAE J1772.

O

Open Charge Point Protocol (OCPP)

A communication protocol that enables the interoperability of central management systems and charging stations from various vendors.

P

Plug & Charge

This technology enables an electric car to speak with the charging station so that, once connected, the car will begin charging on its own without the need for extra verification.

Q

Quick Charging

A phrase that is frequently used synonymously with "fast charging," and it usually refers to DC charging that quickly charges batteries.

R

Radio-frequency Identification (RFID)

Using a tag or card, radio-frequency identification, or RFID, is a type of wireless communication that is frequently used to identify users and give access to EV charging services.

S

Smart Charging

Charging that uses intelligent process management to schedule charging sessions for periods of reduced electricity costs or increased availability of renewable energy sources.

T

Tesla Supercharger

A system of exclusive fast-charging locations that Tesla designed specifically for their cars and that can charge cars at high speeds.

U

Ultra Fast DC Charging

The fastest EV charging technology currently on the market, typically delivering power deliveries beyond 100 kW, and greatly surpassing the power delivery of typical fast chargers.

V

Volts

The electromotive force or electric potential differential unit. It is a measurement of the electrical force that the charger provides for an EV.

W

Watts 

The International System of Units' standard unit of power. It measures how quickly energy is transferred. utilized to gauge charging power in EVs.

Z

Zero-emission

Vehicles or procedures that release no pollutants into the atmosphere. Since they don't emit exhaust like conventional cars do, electric vehicles are regarded as zero-emission vehicles.
