As per the e-vahan portal (Ministry of Road Transport and Highways), at present there are about 8.77 lakhs active electric vehicles are on Indian roads as on 08 December 2021. Check Details

Along with pure battery electric vehicles (BEVs) there are two more types of EVs. Plug-in Hybrid electric vehicles (PHEVs) and Hybrid electric vehicles (HEVs).

Yes, electric vehicles are better than ICE vehicles as the former emits fewer vehicular pollutants. A CNG-powered or fuel-powered vehicle contributes to more particular emissions. Higher fuel and energy consumption harms the environment. On the contrary, EVs are more efficient as more than half of the energy is used in the propulsion of vehicles, and a very less amount is used in friction force.

EV charging isn’t as linear as fueling a fuel tank. Charging an electric vehicle depends on various factors such as vehicle type, charging equipment, power source, etc. Charging a larger battery pack may take more time than the smaller one. However, the power source is the main thing which clarifies the charging system.

EV charging can be classified in three levels
Level 1
Charging at home is very slow and takes hours.
Level 2
Charging at public charging stations takes a few minutes to an hour to charge an EV. The charging speed depends on the power and voltage an EVSE deal in. 
Level 3
It refuels electric vehicles at speed as charging is done through DC fast chargers. However, the fast-charging EVSE network is very less. 

Rang anxiety is a driver’s fear regarding energy storage to cover road journey or reaching a charging station before car range signals refuelling. It is a major psychological barrier against users’ mass adoption of electric vehicles. Buying an EV against the mass adoption of e-mobility is a big deal in developing countries like India, where EV ecosystem is still in its initial stage. Range anxiety is obvious as India still needs to develop sufficient EV charging stations.

Like ICE vehicles, things can go wrong in the case of electric vehicles due to their electric malfunction. Although electric vehicles has fewer movable parts as compared to ICE, vehicles still have lithium-ion batteries which emit a lot of heat when used. The thermal management system plays a critical role. If gone wrong, it is prone to catch fire, and this can lead to lethal accidents. 

As per the e-vahan portal (Ministry of Road Transport and Highways), as of December 2021, Uttar Pradesh with 2,58,105 electric vehicles is at first position in India. Check details

As per the information received from Department of Revenue, at present the GST rate on electric vehicles is 5%.  The GST rates are prescribed based on the recommendations of the GST Council.  Electric vehicles are already at the lowest rate slab of 5%.

Under FAME-India Scheme, incentives are provided to buyers of electric vehicles subsidy in the form of an upfront reduction in the purchase price of electric vehicles. 
The incentive is linked to battery capacity i.e. Rs. 10,000/KWh for e-3W and e-4W with a cap 20% of the cost of vehicle.
Further, the incentive/ subsidies for e-2W has been increased to Rs. 15,000/KWh from Rs. 10,000/KWh with an increase in cap from 20% to 40% of the cost of vehicle w.e.f. 11^th June, 2021. Details on Vehicles & Subsidy

As of March 2022, as per the data available with Bureau of Energy Efficiency (BEE), there are 1633 public EV charging stations, installed by various entities and are currently operational in India. reference

In January 2022, Ministry of Power, Government of India had issued “Consolidated Guidelines & Standards for Charging Infrastructure for Electric vehicles”. Detailed EV Charging Guidelines for 2022 are available here

Government of India has made charging a de-licensed activity meaning any individual/entity is free to set up public charging stations without the requirement of a license provided that, such stations meet the technical, safety as well as performance standards and protocols laid down  under the guidelines as well as norms/ standards/ specifications laid down by Ministry of Power, Bureau of Energy Efficiency (BEE) and Central Electricity Authority (CEA) from time to time.

The current GST rate on EV Chargers is 5% ?

The GST HSN Code for EV Chargers is 85044030.
