This not-standard (business) was the case for mobiles too when we look back. It did not surprise me when every (mostly) manufacturer moved to USB charging over time.

I wish and hope the same thing happens here too. As more manufacturers adapt, the costs should come down gradually because of mass production. There should have already been an alliance or association of EVs, doesn't it exist?

If you would fully read the very article you are quoting, it actually argues that battery swapping is not possible.

Some of the arguments in this are about climate conditions like in Canada and business situations. I'd trust technology to overcome these challenges over time and make it possible. Not that the vehicles have one huge single cell battery. There are ways to make multi-cell smaller batteries with swapping in mind.

Even better would be that, EV manufacturers get away from owning batteries and make open battery engines. All they need to specify is KWh and physical battery bay dimensions.

The NIO website shows it can be done. Caranddriver.com has highlighted this. "Nio's battery-swapping technology has been available since 2014, and as of June 2020, the company had completed 500,000 battery swaps."

NB: One of my friends is looking for an EV in the USA and he was explaining about Chinese cars that come with battery swapping facilities. So I raised this one in the thread.

Once again, please fully ready your own article. It provides various detailed reasons as to why this is not likely to succeed. Only one company has done it at a small scale and for taxi drivers confined to a small area. The 500,000 swaps sounds like a lot but it is over many years. One single taxi can swap it 1000 times per year and a fleet of 100 taxis could swap them 500,000 times in 5 years. There is no way every car company would give away their proprietary technology and adopt the Niro standard as expected by that company. In addition, building a charging station is much easier and cheaper than this kind of infrastructure. If there are two such swap machines and it takes say 10 minutes per car and there are 10 cars lined up, we are talking about an hour if all goes well. In the same amount of time you can charge their batteries at a charger bank which is easier, cheaper to install and can service any kind of vehicle whereas this works only on one companyís vehicles. In addition, if I have a new and well cared for battery, I wouldnít want to swap it with some unknown, possibly older and worse performing battery.

If one charges for 10h overnight, even a 1.8kW charging point would usually suffice (assuming no possibility to charge at office).

If your daily commute is so long that you need to fully recharge the EV every night, then you are probably better off with an ICE car.
I guess people conveniently forget this part and lump all EVs together.

Most of the average car's time is spent sitting and waiting for the next drive. I think I am among the average person and have a two hour round-trip commute each week-day and maybe two hours of use each day on weekends. I am able to easily top-up the charge at home when the car is parked there.

If you are one of those users that takes 500km road trips every weekend and then decide to switch back to an ICE vehicle, then clearly those people did not do their homework. If one has a use case that is not satisfied by their current vehicle (EV), then do what we all do - rent a specific vehicle (ICE) when required.

I think the bigger problem to EV adoption is that a lot people do not have a dedicated garage to park and charge their cars at home.

As pointed out, that study may be a bit old. However a number of issues remain as far as India is concerned:

1. The electricity rules at present do not permit sub-metering ie you need to take the power from your existing connection. Now in an independent villa or bungalow, you can easily install a charger in your porch or garage. But in an apartment block, you cannot run a cable from your flat down to your parking slot. The society cannot lay cables centrally unless all owners agree to share the electricity costs equally and obviously that won't happen. You can't have individual meters at your parking slots as that would be sub metering, which isn't permitted.

2. Similarly in your office parking.

3. Hence, if the Govt wants to promote EVs in India, some changes need to be made in the Electricity Act, to enable societies to enable users to pay only for what they use.

4. The other issue that doesn't seem to be getting addressed is, what do we do with all the used batteries when EVs become popular? We are likely to have mountains of used batteries on our hands which will create another environmental problem.

5. IMHO, EV Two-Wheelers in India are a great idea in cities, as they bring down the air and noise pollution and could possibly reduce the number of road accidents also being somewhat slower than the petrol bikes.

My two bit worth.
Cheers
