Anyone here has bought an EV ?
What I have understood is that 40% of the cost of an EV is the battery and that despite warranty has a high probability of giving up in 8 years and you are left with an highly depreciated vehicle with no resale value since the cost of battery replacement is the cost of the vehicle.
Any research/view on it ?

I had the original Reva (before it was bought by Mahindra) and used it for four years. @60 km range per full charge Eco mode. It used lead acid batteries. Sold it for approximately half the price after this.
I have an electric scooter that I bought used for 50k (4 years old) that I don’t use much.
I also have an electric pedal assist bicycle - Qubit (30-35 km per charge) that I use almost every day.
Dreaming of a Hyundai Ioniq 5. But @ 45 L it’s a bit far away. Maybe in a year or two used ones will be within reach .

The official design life of an EV battery is 15 years with half of that life warranted. The other thing to note is that cell degradation is significantly higher than the assumed degradation when ambient temperatures are higher than 30 degrees which is the case in our country for most of the year. I have my doubts whether the current crop of EVs will even survive for 10 years in Indian weather before their batteries give up.

So far only the benefits of EV are being highlighted. The cons seem to be quitely sidelined. The charging time & stations ( the driver nightmares regarding functionability of charging stations on highways are stated in Team BHP) as of now are still in its infancy and God know's how stable the batteries will be in the long run in the not so conducive weather and driving conditions.
Hoping that there will be a proper way to recycle or dispose unusable batteries in the future which are even more detrimental to the environment.

I have spoken to several early adopter- owners of EVs. Every one of them (so far) has expressed satisfaction with their ownership and usage experience.
But I can understand how “range anxiety” combined with poor public charging infrastructure could be a significant factor in deciding on EVs

For short runs within the city, EV's may be fine. True test would be for long drives in the heat where charging stations are required or during monsoon road flooding.
After 10 to 15 years maybe the feasibility here would be more clear.

Every new innovation (eg: New tech, EV) follows patterns which are predictable to an extent. Once such is the The diffusion of innovation theory, popularized by Everett Rogers, explains how, why, and at what rate new ideas and technologies spread through a social system. It outlines a predictable pattern of adoption, with different groups adopting an innovation at various stages, from early innovators to laggards. This theory is crucial for understanding how new products, services, or ideas become widely accepted or fail to gain traction.

Key Concepts:

Innovation:
A new idea, practice, or object that is perceived as new by an individual or other unit of adoption.

Communication Channels:
The means by which information about the innovation is transmitted to individuals within the social system.

Time:
The amount of time it takes for an innovation to be adopted, which varies across individuals and groups.

Social System:
The network of individuals, groups, or organizations that are involved in the diffusion process.

Adopter Categories:
Individuals and groups are categorized based on their willingness to adopt innovations:

Innovators: Venturesome, eager to try new things.

Early Adopters: Opinion leaders, respected by their peers.

Early Majority: Deliberate, adopt before the average person.

Late Majority: Skeptical, adopt after the majority has already done so.

Laggards: Traditional, resistant to change.

Rate of Adoption:
The speed at which an innovation is adopted within a social system, influenced by factors like the innovation's relative advantage, compatibility, complexity, trialability, and observability.

How it Works:
The diffusion process typically follows an S-shaped curve, with a slow start as innovators adopt, followed by a rapid increase as the early and late majorities adopt, and finally a plateau as laggards are reached. Understanding these stages and the characteristics of each adopter category allows for targeted strategies to promote the adoption of innovations

I read somewhere that new buildings in Mumbai are going to have a provision for EV charging just like other amenities . So eventually with combined effort of all the stakeholders , charging issue should be resolved in few years . Govt has already started its pilot project in Delhi of coercing people to let go of their old vehicles . Now on hold after public outcry . So seems like GOI is serious .

Hope they don't burn more coal to generate more electricity for EV's and would resort to a green source of energy. Else it is back to square 1 by taking another route.
If I am not mistaken Delhi govt have revoked the ban on old vehicles. If an old vehicle is well maintained and well within the PUC criteria, then banning it does not make much sense. More than the age, the emission of the vehicle should be taken into account.
I guess very well maintained vintage vehicles would have to be scrapped then.
