Hi Friends,

Even as I launch this today ( my 80th Birthday ), I realize that there is yet so much to say and do. There is just no time to look back, no time to wonder,"Will anyone read these pages?"

With regards,

Now as I approach my 90th birthday ( 27 June 2023 ) , I invite you to visit my Digital Avatar ( www.hemenparekh.ai ) – and continue chatting with me , even when I am no more here physically

HOLY GRAIL : NO BATTERY CHARGING STATIONS ?


Holy  Grail  for  Electric  Vehicles

------------------------------------

For Electric Vehicles , holy grail is : No need for any Battery Charging stations  !


World over, auto companies are coming out with EV which depend upon heavy and expensive Lithium-ion Batteries , which require , anywhere between 3 hours to 6 hours for re-charging , after running for 200 – 400 km


In turn , that requires setting up a massive infrastructure of thousands of Battery Charging Stations , all over the country . Currently , India has some 60,000 Petrol – Diesel filling pumps , which can fill up your car tank in less than 5 minutes !


If it takes 200 minutes to re-charge a Lithium-ion battery , how many re-charge stations will be required ? – even assuming that a car owner does not mind waiting at the battery charging station for 3 / 4 hours !



So , the “ Holy Grail “ ( 5G ? ) for electric vehicles boils down to the following options , none of which need a Battery Charging Station :



ISRO technology

This consists of a very small Lithium-ion Battery ( 5 Kw ) , continuously being charged through its Solar Panel Roof top  . ISRO demonstrated this in May 2017 but strangely no body talks about it !

ISRO : the EV Game-Changer

Solar Panels charging Li-ion Batteries of Electric Cars ?

Stotes-Dot Technology

The three-year old Israeli startup, named StoreDot, is working on a prototype EV battery that can charge in as few as  FIVE MINUTES , and provide 300 miles of driving range.


StoreDot’s  “ FlashBattery ” technology is based on proprietary inorganic compounds and a hybrid multifunction electrode (MFE) and promises a theoretical “instant” charge for smart phones and electric vehicles.


 “If this chemistry works as we show, there’s no reason we couldn’t charge a car in FIVE MINUTES ,” says CEO / Founder of StoreDot , Doron Myersdorf.

Aluminium Battery (  Metal Air Battery )

From web site of Phinergy :

 

Phinergy’s air-electrode technology has enabled it to master the metal-air reaction process and develop an aluminium-air system with a lifespan of thousands of working hours, relieving the main constraints of electric transportation and clean distributed generation.

==============================================  

 

 

 

 If Indian auto industry can get together to develop / commercialize , one or more of the above mentioned “ Battery Innovations “ , it can leapfrog the EV manufacturers all over the world .  India may even succeed in exporting EVs all over the World !

 

Dear Shri Gadkariji,

 

Current investment in the existing 60,000 Petrol-Diesel pumps is Rs 6.5 lakh*crores

 

If 30 times more Battery Charging Stations are needed, then that could cost Rs 195 lakh*crore  !

 

 

So, how about allocating Rs 300 crores as done by the Department of Telecommunications to develop 5G technology , as explained in the following news report :

 






More than 200 researchers, students and teachers from across five Indian Institutes of Technology have joined forces over a Rs 300-crore project to develop 5G technology and its use cases in India.
 

The department of telecommunications-backed project, being billed as the biggest collaborative effort between these institutes, will aim to develop a comprehensive test-bed for 5G that can be used by technology companies, telecom operators, academics and start-ups for R&D purposes and developing 5G products and solutions.



The project has the government’s full backing—Finance Minister Arun Jaitley had said in his Budget speech that the telecom department will support a 5G technology test-bed that will be anchored out of IIT Madras and whose roll could be expected in 2020, in line with global roll outs.

The institute will also help in the overall testing and integration of all sub-system modules and the demonstration of the complete functionality of the final test-bed. 

=======================================================
Why cannot we do something similar for Auto Industry , which must switch over to Electric Vehicles by 2030 ?
