EV Industry Terms -1

With the development of EV industry, many words are beginning to be very popular, but we do not really understand these industry terms,what is EV, what is EVSE, what are Mode1, 2, 3, 4, IEC62752, IEC62955 and so on what are the standards, what are PiP, IET. As the manufacturer of Ev charger parts, let's get to know you!

1.Basic Abbreviation

EV =Full electric vehicle or electric hybrid vehicle

EVSE =Electric Vehicle Supply Equipment

AC=alternating current

DC=direct current

Fast Charge =Normally 16amp or 32amp AC charging

Rapid Charge =Direct current (DC) charging

2.Charging Modes, Types, Levels and Detection requirements

Charging Modes=Charging "modes" are used to categorize the mode of power delivery, protection installation and communication/control of charging system. 

There are 4 different EV charging modes, defined by the international standard IEC 61851-1.

Mode 1, Mode 2,Mode 3, Mode 4 are the charging modes of the AC&DC EV charger

Mode 2 =Mains AC charging, usually utilising a 13amp socket and built-in IEC61851-1 communications unit within the charging lead

Mode 3 =Mains AC charging from a charging station with built-inIEC61851-1 communication

Compared with Mode 1 & Mode 4, Mode 2 and mode 3 are common among the market.

Charging Types=Charger "types” are used to categorize the different socket-outlets used to deliver power in the charging system. 

There are many, but majorly 3 different connector types defined by the international IEC 62196-2.

Charging Levels=Charging "levels" are used to categorize the rated power, voltage and current of the charging system. 

There are 3 different EV charging levels, defined by SAE J1772

RCD=residual current detection, it also means the fault current detection, the leakage current detection.

3. Standard

IEC62752=IEC 62752:2016 applies to in-cable control and protection devices (IC-CPDs) for mode 2 charging of electric road vehicles, hereafter referred to as IC-CPD including control and safety functions.

IEC62955=IEC 62955 applies to residual direct current detecting devices (RDC-DD) for permanently connected AC electric vehicle charging stations (mode 3 charging of electric vehicles).

J1772 =Type 1 charging usually via a 16amp or 32amp tethered lead

IEC62196 =Type 2 charging usually via a 16amp or 32amp socket

4. Others

Communication unit = Normally referred to as comms unit, being the unit based in the

charging station that communicates with the car to initiate and deactivate charging sequences

Tethered lead =Usually a Type 1fixed cable and plug charging solution permanently affixed to the charging station

Dummy socket =Sometimes referred to as a stowage socket and usually used to store a J1772 Type1 charging gun

LED status indicator =Changes colour to indicate the status of the charging station / point

OLEV =Office of Low Emission Vehicles, a team working across government to support and

encourage the uptake of electric vehicles

PiP =Plugged in Places, a government funded project to encourage the installation of electric

vehicle charging points by providing grant funding

IET =Institute of Engineering and Technology

We can share abbreviations, industry terminology and so on but they are limited, but our learning and development in the EV industry is unlimited. If you need us we will bring you more knowledge of the EV industry. For more information, please log in to www.ivy-metering.com to learn more about new energy sources such as EVs and PVs.
