Simplest EV Conversion under $3000 - Convert Your Car in 3 Days!

- čas přidán 4. 09. 2022
- Petrol is expensive! In 3 days I converted my petrol car to electric using what I think is the strangest yet simplest EV conversion technique. In this video, I'm going to walk you through how I converted the car, and show you all the modifications I made to the engine using a toy model.
This technique gives the car power steering and air conditioning without any additional motors! Leaving in half the engine saves you the time, money and effort it would take to pull out the engine and machine out motor mounts and brackets.
The converted car uses a single 6kW, 72V BLDC motor connected to a 350A Kelly Controller. In the trunk, you will find the 72V 100Ah Lithium Ferrophosphate (LFP) battery.
To retain power braking, I did have to add an electric brake booster vacuum pump to the car, to provide the brake booster with the vacuum it needs to assist you during braking. Also, since we don't have an alternator in the car anymore, I used a 72-12V DC-DC convertor to bring the 72V from the LFP battery in the back down to 12V to charge the lead acid battery to power the central locks, power windows, and the car's lights.
While the performance of a conversion like this would benefit from a larger motor and battery, the current specs produce the perfect city car - with a top speed of 60Km/h and a range of 80-90Km - you'll fit right into the Gurgaon traffic! Best of all, the car costs you less than ₹1/Km to run!
I really hope you enjoy this video and would love your thoughts and feedback in the comments! Please feel free to reach out to me for any questions you may have - I would love nothing more than to be a part of your switch from dinosaur bones to electric power!

I am an Automotive Design Engineer and even in the wildest of my dreams I could've never imagined to covert an IC engine car into an EV by keeping the lower half of the engine intact with rest of the car. Kudos to you man.
That's because it's a bad idea.
I'd imagine the electric motor would be more efficient if it didn't have to drive the bottom end of the engine still.
Not to mention carrying it around adding weight to the vehicle
@@1974UTuber I do understand your point but this guy has converted his old car into an ev without spending a fortune on purchasing custom parts. If he had not done so he'd have to spend a huge amount just to get the parts fabricated.
Looks soo simple. I mean it was just there... Well done 👏
@@1998IP that's the genius in all this. Granted it comes with somewhat heavy compromise but he's lowered the price ladder for most of us to enter. Kudos to him
Oahu can you see this as a viable inner city transportation service . People could rent these electric cars for short inner city trips etc et
This is engineering at its purest form. Accept a couple of compromises (acceleration, range) at the expense of cost, but with the most amount of features (AC, steering, brakes) using existing components (gearbox) to mitigate the compromises. I'm impressed! Great work!!
From Peter H.
Its truly amazing what he did.
But could he have just added the electric motor but left the pistons in place.
That would be a hybrid.
He could use minimal gas but mainly electric until the battery ran out.
Then all gas.
This is the kind of ingenuity we need right now. Most of the world can’t afford Teslas, this is a genuine option. Well done 🎉
I agree, I think their is a big market for EV conversion kits for a variety of reasons, cost and reviving old cars. There are kits available now but expensive, the best I've seen is an in-wheel hub motor meaning you only have to replace your wheels and add a battery!
They’re not that expensive when compared with their ICE counterparts. You can get a Model Y for like $34,000 after the tax credit. A credit which can be applied to the purchase price of the vehicle. Take that and another $100-200 off for gas and it’s as affordable as a $23,000 vehicle. And that’s brand new.
@@CotyWK What if I don't live somewhere with tax credit? What if I can't afford to spend 23k on a car?
Then you probably can't afford an ice either
@@sensitivedesensitivity7349 if you can’t spend 23k on a car then buy used. They sell used Teslas for $23,000 which is equivalent of $10,000 - $15,000 ice car. Also, maybe try learning a skill that is more sought after than a fry cook? It’s generally acceptable to afford a vehicle that is 20% of your gross income. $23,000 is around a $300 a month payment. You telling me you don’t make $18,000 a year?
I want to say mate, everything about this video is excellent. Your production, the information, the sound and most of all the work you did. You're incredibly talented.
Much appreciated!
So you know how to convert now? I doubt it.
Ru still running this car
agreed. it's so well produced. I'm inspired
criminally underrated channel.
Love this . Imagine converting all your family 15 year older cars to running ones . Mihir beta congrats . We all are so close to our family cars for its nostalgia it’s memories , it’s feel , the emotions and the past that brings warm feelings of our bachpan . Kudos
I hv 2011 "SWIFT DZIRE" diesel Car from Maruti.....It's boot space is beyond any sedan. Today, it's maintenance cost is very low. I am really interested in future EV Conversion.
Just let our Minister Nitin Gadkari ji allow this everywhere(he's promoting Old Vehicle Scrappage policy instead of "EV kits")
I am already in contact with local EV Converter
Save the parts you take out incase you endup going back to petro or diesel. It will be interesting to see how it does for range and time to recharge!
Enjoy your Projects!

@@abhijeetchavan13 bad idea
@@harrygregory6227 how?
Wow. You not only revived a classic car but also done a fabulous job making it an eV. I really appreciate it.
He could have travelled 37500 kms with 3k usd. But it's not about that, it's the madness, passion...
You sir are a true humanitarian! You took something that is genius in its simplicity, and you demonstrated how even a simple person like me can do this - and now I fully intend to.
You have my gratitude.
Edit: Now that this video exists, I hope we will see pthers (who knows - mayne even me!) showcasing EV conversions they've done based on this concept.
I love this. While most of car conversion videos simply show sped up videos without explaining or explaining in hours long series of videos, this was crisp short and sharp to the point. Good starting point for anyone into this experiment or venture.
Well done Mihir! Some people don't think creatively how to simplify & minimise the changes, so the challenges are too big & expensive, so they never get anything done... but here you got the job done by just doing the needful (my favourite Indian English word)!
If you can explain something to someone and they instantly feel they can do it then you're a great teacher. My man, right now I just went outside looked at my car and said I can convert it now now to be an EV
This is awesome, Mihir! So proud of you and can’t wait to see what you do next!
Brilliant work Mihir! Love the elegant simplicity of the conversion. Keep the innovations coming!
Such a unique solution to an EV conversion. Great job on explaining how you went about completing the conversion. Grandad should be proud.
Echoing the other comments on here, great project and great video! It's obvious you really took your time with the cinematography, script and editing. Also, nice meeting you at Open Sauce today!
i am shocked that you only have around 7k subscribers.. man, you deserve more.. love your project mate!! keep it up..
I love how we didn't get to see anything of the actual conversion and the engine bay with minimal detail
For the cost, this is the most innovative conversion I have ever seen! Kudos to you man!! 🎉
There is a huge potential for scalable , well manufactured 3 wheeler conversion kit. Even if it costs Rs 1 - 1.5 lakhs for a 4-5 KwH LFP battery, the savings in fuel can make it completely worth it.
Once LFP battery crunch reduces in 2-3 years as domestic production starts coming up, I am sure we will see a lot of these conversions becoming popular for urban use. Govt. should definitely incentivize the same
Great work. Ingenuity at its best. This has been playing in my mind for a while. Happy to see it in action. It’s a Multi million dollar venture.
Love the fact that you admitting it is not perfect, but it works. Excellent presentation.
This is next level genius in action!
Definitely out of the ordinary, but a really good watch! The fact you kept half the engine intact and it still works is amazing!
But now you got weight half engine
really crazy to see someone at your age do inspiring things like this. keep up the good work mihir
Well done Mihir! This is superb! Since you left the car behind I will use it for my commute to work!
Can I get the number of that Mechanic Ustad Ji? I want to convert my car too in EV
Extremely impressed Mihir. Well done. I am watching this from Pakistan and with the prevailing high cost of fuel, your video is like a breath of fresh air.
Shsbaaash is the word that pops out of my lips. It’s a year too late ( from your submission of this video) because I just watched it. Very inspiring!
If the conversion cost is low then one doesn't mind changing engine oil every 10 thousand kilometres but this was a really cool and out of the box conversion . If you could get better batteries, better finishing, tweak the performance up a notch and replace the fuel tank with an IP 68 battery pack , this could very easily transform into a flourishing business of conversion kits , like it is with CNG conversion kits.
You really have great auto knowledge & passion despite being an Indian woman. Engineer by any chance ?
That's true, the engine oil would work even longer than 10k kms as there is no combustion happening, so no heat or combustion gases or fuel to degrade the oil. There are a lot of ways to build an electric car, but it all boils down to how much money is spent. The key is ingenuity, people in developed countries have access to funding and parts which are not available everywhere in the world.
Great work. You make it appear so simple but there are few who can innovate and implement.
I admire your professional approach to this video and the conversion as a whole. You will achieve big things, Mihir.
Awesome video and ingenuity. I am at the point where my 2010 Hyundai Accent is in trouble and just questioned to myself if I could convert it to EV. Possibilities are obviously there. Thanks for sharing.
The fact that he's able to do this with a relatively tiny battery because of a Gearbox, tells me that there's space in the EV sector for Manuals, IF enthusiasm for Manual cars persists.
Not only that, if pairing an EV with a transmission means you don't need as powerful motors or batteries, it means that EVs can be more efficient and even more environmentally friendly because you won't need the huge battery packs. Am i crazy or is there a future for the transmission here?
my 2 cents ... xmission will hardly make a difference as in motor peak torque is immediately available
in case of engine torque is gradually developed so is the power and hence you need transmission manual or automatic with multiple gears for various reasons
only possible benefit of an transmission for ev would be in my opinion for inclines or slopes if u dont want the hill climb n hill hold n other modern tech
I love this line of thinking. I want a manual electric!
nice epic bro duded
Congrats for your innovation. My doubt is motor has such power to drive the crank shaft & piston moving up & down.u removed spark plugs. Is there any drawbacks.
Steam cars also don't need a transmission but some White steamers had a two speed axle
Amazing work! The model is very well explained, especially for the ones who are not acquainted with such technical information.
Brilliant approach to reusing as much of what is there as you can. Love it.
Great idea and an equally interesting execution. Good job, Mihir!
Well done Mihir! Amazing work - environmentally friendly and budget friendly too! Love this and hope to see more cars running this way soon!
the battery is not environment friendly, its exporting pollution to another mining country.
@@rajanathanc5468 Good comment. However, try to research the whole carbon impact of ICE vs EV and compare. You will be surprised on what you find.
This is a really bad idea overall, the conversion is only to showcase what can be done. The battery will have a very low life expectancy, it charges slowly and the whole conversion is a joke. The airpump to brake is one of the worst ideas in there, with huge scary implications, the chance of electrical fires is oof the charts with the way this is done, the gearshaft is going to have a bad time with the way it is used and so so many more.. for the cost to fix all these, go research other PROPER conversion kits..
@@rajanathanc5468
this conversion is not efficient BUT still much better than petroleum based cars in many ways , including environment & human lives.
have you EVER wondered about the carbon & other footprints of 1) digging oil well 2) refining 3) transporting oil - oil spills in the sea 4) transport upto your petrol pump 5) the waste lubricating oil every quarter.
now ! an electric car with 10 kW motor can give you sufficient speed for city rides. ( this has ONLY about 5 kW).
5 kW will consume less than 7 units of energy to go 80 km. ( this system being less efficient , may consume 9-10 units max).
compare it with the petrol car , giving a mileage of 16 km/litre ; it will consume 5 litre petrol for the same 80 km journey !
now, even thermal power plants (coal based ) are more than 90% efficient.
& no country being bombed e.g. Libya or Iraq ( or Ukraine if you think about it )
& no funding of a terrorist state like Pakistan by the petrodolar economy.
now , think outside the propaganda created by the petrodollar , God bless !
@Pravin Dahiya nice interpretation, but replace petrol to lithium, rest all activities from mining to recharge is same.
Petrodollar to lithodollar
This is a really cool and creative way to repurpose an older vehicle!
I'd be interested to know more about what motor you used and the speed control.
If you were willing to source some used parts you could fit the braking system with hydroboost (a loop from the power steering pump) and eliminate that vacuum pump.
This is popular and well documented retrofit here in the U.S.
you mean the "worst use of battery tech" v12 and a manual is better
This is recycling the typical way it should be done!
A lot of people use forklift motors and I’ve heard some people use golf cart controllers
@@harrygregory6227 dude do u even follow this guy.... Santro and v12 engine....dont make me laugh
He said that info is on his website.
Truly "out of the box" thinking. You are incredibly talented.
When you met a challenge, you over came it with creativity.
You've done an amazing job man...... wishing you luck for your future ❤️
Well done and very ingenious. I would pull the pistons of the engine too, to eliminate any unwanted friction losses as well as to reduce weight. Thanks for a great video
Exactly 👍
Bro your videos are great and the quality is amazing, criminally underrated channel ❤
It's not exactly the first EV conversion, but it does feel like your first time! Great job! 👍
Well done Machang, you are the hero of petrol cars conversion sifu! Cheers!
You must make it into a standardized mod and make it into a business. I assure you many investors will be ager to invest and it will be huge within no time.
Keep it as simple as possible.. Genius idea
Great Job. I wish I had known you a few months earlier before I disposed off my car.
Wow, what an idea!! Thoroughly impressed!! I do have one worry however, and that is the timing belt and how it will cope with the extra stress of driving the wheels. Perhaps you should consider swapping to a chain. Blown away by your ingenuity though, and i promise to build something similar
Wonderful conversion of and ICE car to electric car. Although I am ICE guy since 1960 when I did Ph D, I love the conversion Mihir has made. I give him top score, my love and wish him more success in his future efforts.
ICE stands for internal combustion engine...
Wow first time someone had explained everything in the most simple manner
This deserves more recocnition, interesting and cool project and i 100% support this idea
i would love to see you document another more focused EV build. your production is fantastic
Awesome job Mihir. As always live your innovations - that are budget friendly and highly relevant. Keep innovating
Uff... why didn't I think of it! What an IDEA!!! What a fantabulously incredible idea indeed!!! A soothing presentation to top it all!
I cannot get my head around this man...i mean how is this even possible and that to as a successful diy project where everything in the car functions as intended 😮😮😮
Kuddos to you and your team, amazing concept and great enginuity, enjoyed watching your build.
In my view depending on the vacuum pump for your break is a bit risky, instead using a compressor with a reservoir would have been ideal, but yeah it would increase the cost because of more parts and for the modifications to the breaking system to work on compressed air.
Hi, you can easily fit the battery inside the fule tank by cutting of the upper roof of the fuel tank and modifying a bit and then putting the seat back on, I'm not sure if it would work out but I think it could be something to think about.
You're onto something with this. Maybe add a bit of reinforcement for the weight of the battery if necessary
Dude , The algo brought me here and I love the channel - kudos!
Kudos to you my guy, brilliant and very thoughtful, not that I know any better but very thoughtful conversion with minimum intrusion.
Dude this is awesome. EV conversations are about to explode and this option is the perfect entry point for a diy tinkerer!
Added to my project list!
Agreed...in fact i just gave my old car to scrap recently...it would have been perfect for this DIY project...im actually sad i did not see this video before scrapping my car 😢
And his idea is genius actually... because everything in the car including the AC works...
Thats a pretty great idea actually, did you ever replace the weaker engine with larger one? Keeping the cam, gearbox and existing transmission on the lower have of the engine is a spark of brilliance. You should patent this immediately and open up a shop to do ev conversions.
This is brilliant, succinct, and incredibly well shot. Thank you for creating this video.
This is fantastic! I have an old suzuki swift/cultus which I may want to do this type of conversion in the future although I still daily drive it. Thank you for the knowlwdge.
So you spent 250,000 on the car?
By posting it on social media/ yt eared more than that
Look at views
@@sushantsharma0367How much do you think youtubers here get paid? 😂
@@sushantsharma0367but it was a risky bet
Great concept!
Also a decent mileage average given that it is carrying so much of dead weight; when compared to a regular EV.
Wow. Now that’s really thinking outside the box, great job. 👏👏
Dude!, that is an awesome project you have achieved! 👍
Brilliant idea! I would never have thought of resuing the crankshaft to lower cost. However, I do have some concerns. Since the car is being powered from the camshaft pulley to the crankshaft via the timing belt, will the load and forces applied be too great for the components to handle? The timing belt wasn't designed to move the car so I am worried that it might stretch or even snap under the load. I by no means am an expert in cars so please correct me if I'm wrong.
I like it,very nice conversation projeçt.
Wondering the same thing here
Just get a spare belt..
Any tiny cars out there with timing chains?
best bet is to go with late 80's to early 90's Japanese cars. not only do they normally have timing chains, the engine designs were simpler thus easier to convert.
Great build. You might want to reconsider engine oil grade to one which flows better at cold temperatures.
but this build will have to keep the motor running all the time event the car stoped, to running the ac? battery will depleted faster,
@@billykulim5202 how's that different from usings different motors? Both will use battery as energy source. Electric motors unlike engines are very efficient and it wouldn't make much of a difference to use a single motor.
@@parasahlawat27 can we just using smaller motor to run those compressor? when the car in idle like in red light will save some energy?
@@billykulim5202 yes you are right but with single battery pack the gains wouldn't be worth having another motor. Plus much of the power in case of engine is wasted in running the engine itself which is not the case with electric motors. Economically upgrading the battery pack would be a more viable option than buying second motor and controller. However used motor from E rikshaws could be viable option.
I believe that you could remove the internals of the engine, keeping only the crankshaft and gear, mostly eliminating the need for oil
I love innovative approaches to solve problems. Excellent
The Electric Car is one thing but the way you presented the video especially the last monologue - You just nailed it man !!!
Congratulations Mihir 👌This is fantastic! Often the most simple inventions as you describe your innovation are the most ingenious ones. It's a perfect answer to a new clean energy fuelled transport with great potential for the whole wide 🌎 Next step is to let the likes of Mr R Tata become aware. Well done 👏 We are all so proud of you 👍Keep it up🙏💕
Tata will come in where he can make tonnes of money.
Keep it up. This the fastest & cheapest way to expand EV market.
Great job! The only question I have is how long is the timing belt going to last if it is expected to handle the traction motor pushing the car along?
Good point! With only an 8 hp motor, it's probably fine. With higher output, the motor would need to take the place of the crankshaft. He could achieve this with a dual output elec motor.
There are some cars that use a chain belt
Fantastic work mate, keep up the great work
Mihir, such a great idea man. Now I feel like I never need to replace my car. I hope and wish your idea soon gets commercially viable with more feasible range of milege and speed.
Definitely want to add regen braking in some capacity though. Not sure it's worth doing the mod in the long run though, as all the extra weight really isn't nessisary, not just the lower part of the block, but the radiator and everything as well.
I think it'd be worth finding a way to just keep the gearbox, and hook up the motor to the drive shaft directly.
Regen is just fancy engine braking. The controller just needs to know when to start regen. Probably tap the brake light switch and that's it.
Unfortunately Regen isn't the magic range extending bullet people think it is. Over the entire battery charge and city driving you'll get around 3-5% extra charge. The bigger advantage is less brake pad wear. But given the funky setup where the whole car is powered through a belt here I would just eat the 3% due to reliability.
@@marsrover001 Dude what? Regen gives you back 50%+ of the energy it took to get you going in the first place.
@@streetguru9350 This information seems incomplete. If you are speeding up and slowing down all the time, maybe regen is worth it. But if you speed up to a certain speed, then maintain that speed for a long time, then slow down, the only energy you get back is the "50%+" as you say of the energy you used to accelerate. As Marsrover001 said, that sounds about 3-5% extra range.
You might want to consider converting the timing belt over to a chain with sprockets. Also, if you are still using the bottom part of the engine, is there some way engine oil is still being circulated to keep the crankshaft bearings lubricated?
I also don't think it has enough range for a normal driver. 80 kilometers isn't enough for most people. And I also think it can be used outside a city. It's basically an electric grocery getter. You know what also fits that description. And electric golf cart. Which you can get for cheaper than a car and 3 thousand dollar EV conversion.
This is pretty amazing - in London, you have to pay so much money to drive a petrol car every day. This kind of conversion would make so much sense! I think there will be a new phase of getting old classic cars and converting them so that you get the best of both worlds.
Keeping the gearbox in was priceless.
Smart work Mihir. Do you have to apply clutch while shifting the gears? Can we eliminate the clutch and shift the gears without throttling during gear shift?
Yep
Bhai...paisa kitna lagaaa
Really interesting idea to repurpose the old ICE block. You didn't mention it in the video but I think you could probably pull the pistons out and just leave the crankshaft. Much less drag that way.
He did that, at least I am fairly certain that is what he said
@@FunctionFIVE I probably just missed it :)
Thanks, thought he said that.@@FunctionFIVE

Love to see more on new and better version.
Excellent job Mihir, this is a very unique method of conversion to EV, kudos to you. You should make this venture a commercial business and talk to the government for some incentives to fasten the process. Wishing you very best!
Really interesting, Ive looked into an Ev conversion a few times but its still a lot of money and a huge headache to do it properly so I like seeing what people do to make it easier. How much weight would you save if you did remove the motor?
I don’t know specifically for this engine, but would guess it weighs about 100-110kg in factory configuration - my 2.0l four cylinder is just over 150kg.
@@savyor1839 I estimated the same
Good eye bruh!
This is fascinating. I would love to adapt this idea to my 1977 RV. However, when thinking about converting to electric, I noticed that heavier vehicles sometimes use dual EV motors, one for the front and one for the rear. I wonder if you used your form of EV conversion in the front, could you use the same setup in the back as well (parts of an ICE engine and the new EV motor) or could/would you use just an EV motor for the rear? Would both setups allow you to steer the front and back separately? I don't see how they would since an EV motor only setup doesn't use the gearbox, so it seems like the two setups would be in conflict. Also, manufacturers, use traction inverters, is that any different than the inverter you used? Is the term "traction inverter" a buzzword or does it actually mean something? Do you think your conversion would work the same if the car had been an automatic?
Convert it to hydrogen, battery EVs are garbage for heavier vehicles.
This is a very cool idea. This gives me a very good idea to convert a contessa into electric. Remember the front hood length. Wow. Great work dude.
This is brilliant. I am thinking of converting my old Subaru 4x4. Keeping the lower half of the engine is a great idea.
Nice job!
One thing you may want to be careful about is the "engine oil" getting water in it. Normally that water gets boiled off when the engine gets hot, but since that will no longer happen, the water will build up. The risk is that the water can dilute the oil, as well as cause rust/corrosion.
Awesome work Mihir. Does this mean that we can get almost twice the range in an electric car with gears from the same battery as compared to an ev without gears. That's incredible. 👌🏻👌🏻
Nice comment, I assume it is ab ironical one, as indeed yes, the range he is claiming with such a small battery, and with gears, and not the gearless motor sounds absurd.
@@KostasTsakalidis Not to mention the loss of power due to spinning over the bottom half of the ICE as well.

Since the engine is still rotating the crank pulley, do you have the oil pump in operation to keep things lubricated? Also, it would be fairly straightforward to put a more powerful electric motor on there. 30 or 40 horsepower would make the car absolutely drivable (the first Citroen was only 9hp, but it was very small car).
One day I hope to also convert a car to electric. I probably won't follow your exact methodology, but seeing you do the swap the way you want to do it is inspiring.
This is incredible !!! Absolutely loved what you did !!!
