7. Mandate and Motivation

8. Motivation and Mandate
• Domestic Policy Goals
 Reduce dependence on foreign oil
 Job creation
 Economic Growth (energy sources local)
• Energy Independence
 Local energy sources reduce price volatility
 Reduce rising oil imports, export of dollars, particularly to unstable regions of the world
 Reduce dependence on few key regions – roughly half of the EU’s gas consumption comes from
only three countries (Russia,Norway,Algeria)
• Climate Change
 Governments around the world have allocated funding for clean technology
 Global support for climate change has gained momentum with Europe leading the way.
 Transportation accounts for roughly 15% of energy related CO2 emissions globally.

24. AC
In case of AC EVSE, the
vehicle has an on-board
charger that converts AC into
the DC first. AC EVSE comes
in different power rating
ranging from 3.3 kW to 43 kW.
TYPES OF
CHARGING
DC
DC EVSE can
supply higher
power rating
ranging from 10
kW to 240+ kW.

33. Types of charging stations
● Public charging stations: Stations available for public use and are
not dedicated to any consumer category.
.
● Private charging stations: charging stations
available for specific authorized users.
● Fleet charging stations: stations dedicated to fleet
charging (Ola/Uber).
● Battery swapping stations: A battery swapping (or switching) station is a place where a
vehicle's discharged battery or battery pack can be immediately swapped for a fully charged one,
eliminating the waiting period for charging the vehicle's battery

47. Challenges in Indian Market

48. Challenges in setting up EV market
A. High upfront vehicle costs-government should consider providing tax rebates and tax holidays, lower goods and
service tax (GST) on electric vehicles, charging stations and associated components and on services rendered by charging
infrastructure operators. Waivers on road tax and income tax benefits can also be considered.
B. Real and perceived range anxiety-Consumer awareness on electric mobility should be created highlighting
total cost of ownership (TCO) benefits, charger availability and range concerns
C. Lack of interoperability and standardization of charging infrastructure-India as a testing
ground should adopt a technology agnostic approach and attain necessary exposure to all technologies to determine the best
possible solution as per the Indian weather and climatic conditions
D. High dependency on government subsidies-If government considers deploying subsidies for the
purchase of EVs the framework should enable a constant improvement in efficiency of the vehicles and gradually decrease the
subsidies
Promotion of indigenous manufacturing of EVSEs and EVs will enable government to achieve cost reductions, create jobs and
further boost the economy.
E. Lack of clarity on expected impact on peak load due to EV uptake-Load flow studies and
analysis need to be conducted to understand if the nodes of network where electric mobility charging assets are planned to be
deployed for viable business operations are resilient enough to absorb the impact of sudden power injection and drawls. There is a
need to study the impact of Variable Renewable Energy (VRE), storage and EV charging on distribution networks in a holistic
manner
Special tariff category including TOU (Time of Use) for residential and blended tariff for public chargers is recommended.
