As you tell in 12: 55 min. I have primary car for long drive and near places i used electric car. Like going to sister house or going to my friend or relative house they all live with 100km range. I go to they house and also charge if needed. The cost of running 100km cost only max 1 rs. I hope as year rollout , charging infra and battery tech will grow. I am expecting that in next 10 to 15 yrs the range of battery if improve.
I've a doubt bro... Why can't we use solar panels in the roofs of cars so that we can put two batteries ,use one for Driving and another for Saving the power... I know it's a weird question But I need the answer bro.....
bro, in case petroleum import is stopped in india . what happens to the automobile industry and vehicle users. i think immediately charging station bussiness will expand. please share your valuable thoughts.
Hi bro .. Explain about the battery life and price of battery if damaged because I own an electric scooter which cost 1.15 lak and I replaced the battery after 3 years which cost 75k it's price is more than the half of the cost of the entire vehicle If an electric car battery also cost more than the half of the cost of the car all our saved money on electric vehicle will not sufficient to buy an battery itself.
Bro, Your work is awesome and highly commendable... Please do a Video about CNG/LPG Cars and axplain its advantages and disadvantages "ARAI Approval" Thanks in advance...
1.If EV user increases, electricity cost will increas. Moreover fluids user get benefits because maybe fluids cost will decrease the more possibility they have. 2. There are no complaints in EV because no one experience on it, that will become as soon. Sometimes battery life affects, motors any of the parts will damage or affect. 3. And some.
Yeah agreed ryt now it's EV blooming stage and we all praise its advantages eco friendly etc.. Bt we have to think about the future of using EV. If the EV users rises Thn there will b a shortage of electricity r the govt hv to produce much electricity and we know that our country produces electricity majorly Frm coals (60-70%), so increase in demand of electricity will force govt to produce much electricity Frm coal and tht will produce much air pollution Thn ryt now (may b double). And secondly bro its maintenance cost is as much high Thn a fuel cars since battery is the main hero in the EV. There might b a chance of changing the battery Arnd 4 yrs r max of 5 yrs. Since inside d battery there is a series connection of small lithium battery any one damage in a small battery will lead to disposable of the whole battery itself. Third point is if EV users increase Thn the lithium will b a become extinct resources and extraction of lithium does requires much amount of water source agn same it will also affect the environment in short EV r indirectly affecting the environment whr as the fuel vehicles affect directly. So according to me We should find another alternative for fossil fuel vehicles and we can't accept EV as an alternative for it...
Presently Hybrid (runs in electric & fuel) Cars are also available, no need to buy primary (fuel) and secondary (electric) cars. Please promote electric vehicles for better life and pollution control bro

It is by far the best way to give back to our environment. Ppl can start to use solar panels to generate electricity and use that to charge your cars too. I agree to what you say. Hope things move in positive direction :)
New technologies of batteries are on the way. Which may give you better life time than existing. But cost will be high. EV cost may reduce in future based on demand
Bro instead of instead of trying to increase the battery can we connect dynamos near the motors connted with a belts..... So we can get batteries charged while running... This is my little idea will it work...? What is your thought on this...?
Not only you bro even I had thought of this a lot but the things is if we keep a Dynamo it needs some extra energy even for the dyno to run so there is a energy waste created.So using this also produce the same kind of km even if dyno used to run
After battery warrenty., If anything goes wrong with battery full sets should be replaced like mobile or some sets of unit only. The cost of battery??? Suppose you compare with mobile battery cost of mobile battery approximately not more than 10% of cost of phone. If it's car battery means how much% of car cost???

Ev cars battery technology need to improved... Though currently there is no Petrol cost but after warranty period say after 1Lakh kms cost of battery is 8 Lakhs... Athae cost of petrol if we calculate it might be around 7L (appx 15kmpl mileage )..all Ebikes should come with 8yrs warranty with unlimited kms. Then Ebikes can be good for city use not the E-cars
My opinion is govt should manadte charger points in all petrol stations in a shorter timeframe. Once charging points are available automatically people will start buying electric cars.
Electric car doesn't mean no pollution does electricity is abundant like water.it is considerably producing low emission where electricity is produced.
Bro, i have a quick answer in my mind. You might help useful. Apparently upto our science knowledge we know that water is a very stable molecule. Some say that we can produce hydrogen and oxygen, but to seperate them you need an amount of energy. And then when you burn them it becomes the water again and it produces some energy. Ideally the amount produced is equal to the amount required to seperate hydrogen and oxygen from water. Hence it is impossible for a car to move but only you can do the electrolysis and combustion which gives no extra energy. But there are cars running on hydrogen. It has the same process but electrolysis is done already and you are buying that hydrogen and doing the combustion to receive energy to move the vehicle. Maybe in the newspaper they wanted to catch attention and might have explained this. Anyways broz nothing is impossible nowadays. They might discover hidden features of water and might make it possible. If they find it in future, people will say us as idiot. That we even dont know water has this property that can produce energy. But upto now, no such thing is discovered.
When you explained about the battery range, you didn't mention if this battery can be recharged on the drive(like how the dynamo gets recharged while driving a cycle)
Bro how you could say that electric car is eco friendly may be comparatively better than ic engines but think on this perspective it produces e-waste which is radioactive and it is more hazardous when we all change to e-vehicle there will be more e waste where will we dump those waste which is nondegradable and radioactive. And moreover we have all gone through this occasion like blasting of mobile phones due to its battery so even mobile battery having a huge impact on contrast think about the huge vehicle battery it's really a big query on its reliability. Finally battery has aging neither we use it.

Probably, yes.
