Electric Vehicle Charger|EVSE- Electric Vehicle Supply Equipment

Electric Vehicle charger is also known as electric vehicle supply equipment (EVSE). The EVSE is the basic unit of EV charging infrastructure.

The EVSE accesses power from the local electricity supply and utilizes a control system and wired connection to safely charge EVs

Electric vehicles (EV) can be charged in a variety of ways, depending on location and requirement. Accordingly, charging infrastructure for EVs is of different types and designed for different applications.

Specifications and standards for EV chargers, also known as electric vehicle supply equipment (EVSE),vary from one country to another, based on available EV models in the market and the characteristics of the electricity grid.

CHARACTERISTICS OF EVSE – EV SUPPLY EQUIPMENT

Electric vehicle supply equipment (EVSE) is the basic unit of EV charging infrastructure.

The EVSE accesses power from the local electricity supply and utilizes a control system and wired connection to safely charge EVs.

An EVSE control system enables various functions such as user authentication, authorization for charging, information recording and exchange for network management, and data privacy
and security.

It is recommended to use EVSEs with at least basic control and management functions, for
all charging purposes.

Conductive charging, or plug-in (wired) charging, is the mainstream charging technology in use.

Requirements of EVSE for conductive charging depend on factors such as vehicle type, battery capacity, charging methods, and power ratings.

BATTERY SPECIFICATIONS OF DIFFERENT EV SEGMENTS

In India, transport electrification over the next decade is expected to be driven by light electric vehicles (LEVs), comprising two-wheelers (scooters, motorcycles) and three-wheelers (passenger and cargo).

Apart from these, cars and light commercial vehicles (LCVs) are the other key vehicle segments being electrified.

Electric buses will also be present in significant numbers.

VEHICLE SEGMENT	BATTERY CAPACITY	BATTERY VOLTAGE
E-2W	1.2-3.3 kWh	48-72V
E-3W (passenger/ goods)	3.6-8 kWh	48-60V
E-cars (1st generation)	21 kWh	72V
E-cars (2nd generation)	30-80 kWh	350-500V

EV charging requirements depend on the specifications of EV batteries, as power must be
supplied to the battery at the right voltage and current levels to permit charging.

Typical capacity and voltage of EV batteries vary among the different EV segments,
as shown in Table.

E-2Ws and e-3Ws are powered by low-voltage batteries.

The first generation of e-cars is also powered by lowvoltage batteries. However, these are likely to be phased out in the future, even if they continue in specific use cases such as taxis.

The second generation of e-cars, as seen in the upcoming e-car models, is powered by
high-voltage batteries.

Electric LCVs will comprise of both low-voltage and high-voltage vehicles, depending
on their load-carrying capacity.
