An electric car conversion usually DOES need a transmission. For one thing, on a front wheel drive car, the transmission and differential is one combined unit. The transmission then acts as a place to mount the motor and a way to split power to the two wheels.
For some great ideas on different vehicles converted to electric, check out the listing at the EV Album! www.evalbum.com
This video is one segment of an instructional video I created in 2010 from a home-built electric car I made in 2008. Of course, battery and motor technology has advanced quickly since then, and affordable, commercially-built, Electric Vehicles are now a reality.
This video series covers ONE low-tech and simple way of converting a car to electric. Many of these same ideas and techniques still apply to go-karts, motorcycles, boats, and lots of other projects. We hope that you enjoy watching these videos and learn a little something from them.
A simple electric car conversion project like this one uses
A 0-5k ohm potentiometer throttle: amzn.to/2PwMmoD
A motor controller up to 144V: amzn.to/394QyUh
A DC Series-Wound motor (9-inch diameter typical): amzn.to/2TlqYUv
Battery Charger to match your pack voltage: amzn.to/2Toe0Fl
On this car, we used a simple power inlet: amzn.to/3abNWnI
But that also meant we needed to design a separate circuit to disable the ability to drive while plugged-in. That's a built in feature of the now standard J1772 connection used in modern commercially-built cars.
J1772 Inlet: www.aliexpress.com/item/40000...
You would then pair that with a standard J1772 EVSE: amzn.to/387ixRW
I show the internal connections you need for the J1772 communications at: 300mpg.org/2015/03/31/the-diy...
There are still a few copies of the original DVD for sale. Besides the video, the set also has a DVD-ROM with photos, web clips, and documents from the project.
All profits support our work and go towards future DIY Clean Transportation and Renewable Energy Projects.

what do you think of this? I've done some calculations on a project of mine, but i don't know what is the lifespan of the motors. Turns out that if i use a DC motor (1-1 motor spin to tire spin ratio), i would have to run the motor no more than 850 RPM for my country's speed limit. what do you think about that range of RPM? in terms of motor lifespan and wear (considering that DC motors red-line at almost 5000 RPM if i am right ?) The only things stopping me are the transmission maintenance (would want to get rid of it if i could) , and motor overheating knowing that i live in a region of hot climate. Thank you :)

@@aslt5711 There's no reason to try to spin a motor that slow. The motor will have do draw a tremendous amount of current for the current you would need. The typical way to do it is to connect the electric motor to gear reduction, such as the existing transmission. This allows the motor to spin at thousands of RPMs. It reduces current draw and heat, and increases torque. All commercially-built electric cars use some sort of gear reduction. Even "direct-drive" EVs really have the motor go to the drive-shaft, and there is still some gear-reduction in the differential. The only exception are hub motors. They are a very different style design than a typical motor. No current commercially-built electric car uses those.

Obviously a manual car is ideal for EV conversion, and this appears to be all I can find on the interwebs is manual transmission conversions. Is it even possible or worth converting an automatic vehicle to ev?

Hello Ben ! 👋 Well, I am one crazy guy fascinated by the torque of the electric motors & so the potential they have. Saw your whole series of converting an ICE car into an electric car. So first of all congratulations bud !! Loved it so much that it inspired me ! It's just so amazing !! You're the man 💪 Ok. I don't know if this is the right place to post this stuff but all I want is to give you my best wishes & also to have some suggestions from your side. I'm converting an ICE bike to electric one just like your car project. My bike has a manual transmission already which is but obvious & a very common thing. Now to my issues --> 1. When I am using a maximum 3000 rpm motor & connect it to the transmission, it's not slow speed of rotation or operation of the gearbox i.e. transmission. As the gears are always immersed in the oil & so if I cut the housing, there will be a big issue of oil leakage or when in operation, the oil will come out of the housing. How to seal the oil inside or solve this spillage / leakage problem in order to use the pre existing gearbox with electric motor ? How to solve this issue ? 2. Did you use oil in the 'Geometro's' transmission ? If not then is it really safe to use the gears without any oil at all ??? Won't it ruin the transmission after some rides ? Did you lubricate the transmission at least once before starting to use the vehicle regularly ? 3. Also the oil being very viscous, splashing that oil, as the motor moves the whole system, will consume some power. Won't it drop the efficiency ?? Won't it affects the power output ? 4. Using a transmission will reduce the efficiency because it introduces a bit of losses. So is using transmission really advisable ?? At least in a bike ? 5. How could you shift the gears when you were in motion ?? Is it safe for the transmission ? Was it hard to shift without clutch ? Or did it become hard to shift over the time ? 6. What is the frequency of any maintenance that is required ? Like brushes of the motor etc. ? 7. I've heard that brushed motors are less efficient than BLDC motors. So what range did you get ? & Also is it advisable to use a brushed motor ? 8. Did you do any calculations beforehand ? Or you just added a motor which was available ? What range did you get ? Top speed ? Other specifications ? Like motor power peak torque motor voltage etc...... Please feel free to contact me. My WhatsApp number. +919604010750 Thank you so much ! I will be very lucky to a receive a reply from you.

@@TimpBizkit The amount of torque in an electric motor is so huge you don't need gears. Also, that torque comes from zero rpm and up. That's why electric cars have such massive acceleration. Even my ZS has acceleration in the region of 0 to 60 in around 7 seconds (TBH it feels a lot faster). Especially when you're leaving more renowned cars in your wake. The reason why a lot of electric cars aren't rated for towing is that a lot of manufacturers don't want to tell you how much the range is effected!!. The petrol version of the ZS is rated for towing. I can buy a towbar for mine, but it would not be legal to tow as mine is not rated for it. Towing would drop my range from around 150 miles to around 80 to 90. There are quite a few now that can tow in the Volvo's and Tesla's.

The older models were great. Everything was analog and didn't have any electronics involved, except for the solenoid locking the torque converter to create a "fourth" gear. The newer models are totally controlled by a microprocessor. I don' t think you can get away with doing this anymore. :( ..And if you have a CVT transmission, I don't think it will put up with a high torque electric motor at all. It will probably break in a month. Constant Velocity Transmissions were designed for high gas mileage, not for high performance. Then again, if you have a manual transmission??

Keep in mind that it's no simple task to "just put a motor on....". A motor needs to be properly supported, exactly positioned, and be kept in place.

I'm not saying it can't be done, but I'm struggling to think of any DIY twin motor setups done in that way. The Tropica was a twin motor rear-wheel drive vehicle with one motor on each of the rear suspensions, belted or chained to the rear wheels. Essentially twin motorcycle drivelines. Of course, there were only about a dozen of those built!

You'd never want an automatic transmission for an electric car conversion. Most of the time, you'd be driving an electric version around in only one gear anyway. The automatic would be more expensive, less efficient, and mostly would just get in the way. Electric motors behave like transmissions with an infinite number of gears. They produce their maximum torque from zero RPM and can be driven around normally without shifting gears.

Running an alternator off of the motor will just increase the load on the motor, requiring more watts to move the same distance and will not charge more than the wattage used to move it. It will actually charge less watts than it takes to drive it due to heat losses.

@@rubiconnn I have a solution to this problem. However I am very hesitant to divulge it. Because I've worked some 20 odd years on this problem to get it solved in order to build my own prototype... 1.) If it is not done just right you may have an explosion or fire hazard. 2.) Weight is the biggest contributor to failure. Doing more with less is the answer. But how it's done is the factor. (Have a great day.)

@@johnsavage8873 I got mine at a used car lot. You can look at Craigslist, Facebook marketplace, etc. A used Chevy Volt is a great vehicle for a lot of people. Used Leafs can be very affordable. All depends on exactly what you are looking for. Where you are matters a lot. California has PLENTY of used electric cars, but there are a lot fewer where I am in the Midwest. I bought mine out of Chicago (about a 2 hour drive away) as there were a lot more electric cars there. People will sometimes buy and ship a car, or fly out somewhere to see a car. There are also starting to be car dealerships that specialize in JUST plug-in vehicles. Here's one in Chicago: www.currentautomotive.com Also, try joining an electric car group. There's everything from the EAA (www.electricauto.org) to Facebook groups involved in EVs. People selling a used EV often first just ask around in a group of friends.
