Current Status of EV in India
The Indian Electric Vehicles (EV) market is at a very initial stage comprising of only 2% of the total automobile
sales. 95% of the Indian EV market is dominated by 2 and 3 wheelers. The EV market in India is set to see the
entry of a flurry of new players of foreign and domestic origin in the 2 and 3 wheeler segments.
In 2012 the National Electric Mobility Mission Plan (NEMMP) 2020 was established to promote hybrid and Electric
Vehicles. In early 2018 the Ministry of Power launched the New National Electric Mobility Programme to focus on
creating the charging infrastructure and a policy frame work to set a target of more than 30% electric vehicles by
2030.
EV Charging Basic Theory
EV charging is the process of using EV charging equipment to deliver electricity to the Car’s battery AM EV
charging stations taps into electrical grid to charge an EV. The technical term for EV charging stations is Electric
Vehicle Supply Equipment (EVSE).
Methods of Charring an EV

Three methods of charging an EV (Electric Vehicle)
i Trickle charging method
ii AC charging method (charging from AC mains)
iii DC charging method
Types of Electric Vehicle
i Battery Electric Vehicles (BEVs)

ii Plug-in Hybrid Electric Vehicles (PHEVs)
iii Hybrid Electric Vehicles (HEVs)
Electric traction motor is used in EV. Most EVs can take in about 32 amps adding around 25 miles of Range Per
Hour of charging so a 32 amp charging station is a good choice for many vehicles.
Generally electric Cars charged at home use about 7200 watts of electricity which can vary depending on the
mode and home charger.
A charging station also known as a charge point or Electric Vehicle Supply Equipment (EVSE) is a piece of
equipment that supplies electrical power for charging plug in electric vehicles (including electrical Cars, electrical
trucks, electric buses, neighborhood electric vehicles and plug in hybrids).
Hybrid Electric Vehicles (HEVs)
Today’s Hybrid Electric Vehicles (HEVs) are powered by an internal combustion engine in combination with one
or more electric motors that use energy stored in batteries. HEVs combine the benefits of high fuel economy and
low tailpipe emissions with the power and range of conventional vehicles. (Fig 1)
