Make an Electric Race Car- Have you ever competed in a go-kart race on a car track? Imagine having the ability to build your very own little electric go-kart and engaging in a frantic race with imaginary riders. With just a few basic parts like a toothbrush head, a little motor, and a button battery, you can achieve that exact goal! After constructing your electric racer, make a track out of popsicle sticks and test its speed. Designing, for example, an electric postie bike presents significantly different challenges than developing an electric race vehicle. The year’s student racing events were postponed, giving the ECU motorsport crew plenty of time to begin.
It’s not as tough to build an electric race car as you may assume. We’ll demonstrate how to construct an electric race vehicle in this blog article utilising reasonably priced and accessible components. We’ll also go through the components you’ll need and some advice on how to make your automobile run better. This blog is for all drivers, whether you’re a novice wishing to get into racing or an experienced driver seeking a fresh challenge. Thus, click the link to begin creating your own electric race car right away!
How to Make an Electric Race Car?
Are you willing to pay a few thousand pounds and have a spare room? If so, creating your own electric race car might be of interest to you. We’ll walk you through the process of creating your own race vehicle in this blog article utilising only the most basic supplies. Everything will be covered, from choosing the proper motors and batteries to designing and building the chassis. You’ll have everything you need to construct your own electric race vehicle and test it out by the post’s conclusion!
Due to an increase in the production of mass-produced electric car motors, batteries, and controllers, finding the parts needed for a DIY electric car conversion has been much easier; you can now even buy DIY electric car conversion kits. Along with a small group of students, I built and raced an electric racing car. We approached it in this way. Electric motors and batteries are usually always easy to find. The challenging part of making a racing car quick is making sure that everything functions properly. That is ultimately a difficult engineering problem.

How to Make an Electric Race Car 2023? Step by Step Full Guide
In 2023, are you planning to build an electric race car? Look nowhere else! We will lead you through every step of the procedure in this comprehensive tutorial. Everything from designing the vehicle to selecting the best battery technology will be covered, as well as everything in between. The next great electric race car will be made by you if you adhere to our detailed guidelines.
It’s not as tough to build an electric race car as you may assume. We will walk you through each step of the procedure in this comprehensive guide, from picking the appropriate car and motors to designing and constructing your own race car. We will also provide you pointers and suggestions on how to improve your electric race car. This manual contains all the information you require, regardless of your level of expertise racing. So let’s get going.
Step 1: The Chassis
To participate in a number of British national races, we created this automobile. Visit http://www.greenpower.co.uk for further details. The fact that the race series has regulations that must be obeyed had some bearing on the way our car was built and the materials we used.
The chassis was a simple “Ladder” design built of 19mm square section aluminium tube. This is lightweight, simple to operate, and reasonably priced. Aluminum plates and pop rivets were utilised to connect the various pieces. We used a Greenpower design as the foundation for our car, but we made a lot of changes along the road.
Step 2: The Steering
I didn’t want the youngsters to drive with a “spear” pointed at their chest, so I went with a simple lever steering mechanism. It turned out that this was simple to adjust to, especially for first-time drivers who had no preconceived preconceptions about how an automobile should operate.
For the front wheels, a simple bent 2 mm mild steel setup uses a 19 mm bolt as the king pin. With lots of grease, it works superbly. The steering rods have trackrod ends, which are readily available from bearing manufacturers, to offer a certain degree of give in the system. Hence, there was no complicated alignment needed—just turn the wheels in the opposite direction. We chose not to change the toe-in or camber of the wheels. The wheels are wheelchair wheels with dimensions of 12.5″ x 2.25″. Aluminum once more, as it is lightweight and convenient to buy new tyres.
Step 3: The Brakes
The brakes are occasionally needed during a race even though the motor generates a large amount of drag when it is turned off. We tried using a rented bike disc brake system, but it was challenging to put up and simple to misalign, so we’ll try using a standard bike calliper brake in the off-season. Because the brake levers are mounted on the steering arms and control the rear wheel brakes independently, even at high speeds, this is not a problem.
Step 4: The Motor and Drive System
The 24 volt motor required by the regulations is a wheelchair motor without a slow speed gearbox attached. It uses 20 amps at 2000 RPM. Our current top speed is between 25 and 30 Mph, thanks to the gearing we employed. Since your bum is only two inches off the ground, this is not very quick.
We will subsequently slightly modify the gearing ratio to enhance the top speed to 30 to 40 MPH, if we can do so without overtaxing the motor. Another option is cycle gears, although they could include a complex system in anything that needs to be dependable.
Step 5: The Motor Control/electrical System
It only has to be turned on and off for this. The steering wheel’s red button activates a 24 volt, 70 amp automotive relay, which subsequently activates the motor.
Although being straightforward, this system is reliable and adequate. Throughout the most of the race, the motor was turned off as the wheels turned, although pulsing the switch on and off offered a rudimentary method of controlling speed. To avoid overcurrent, a 70-amp thermal cutout is connected in parallel with the motor. The motor is less than £100 when purchased new, so I strongly advise putting this to protect it.
The motor operates at roughly 80 degrees Celsius while in regular usage. The temperature of the motor can alarmingly rise to about 200 degrees Celsius, where the epoxy glue holding the windings in will fail, but this only occurs under stress, such as pulling away from a slow speed, driving the motor while the wheels are turning, or gearing up the drive excessively in the hope of reaching supersonic top speeds. Because the engine is water-resistant, some teams utilise water cooling, while others, like ours, use fins to provide air cooling.
Step 6: The Body
We sought a vehicle with racing-car styling, a light body, and aerodynamic appeal. Our body is comprised of paper that has been laminated with wood glue; after drying, it becomes light and firm like wood. But, obtaining a decent finish has proven to be challenging, so we’ll consider using thin fibre glass as an alternative.
The general shape is good, but to offer the air flowing over the body a smooth exit path, the rear should be rounded, and the top cover should have a little aero screen and be closer to the driver.
Step 7: Batteries
These lead-acid batteries are common in automobiles. Two for every car, one on either side, directly in front of the back wheels. They are easily interchangeable because they are secured to the chassis by a simple bar and threaded rod set-up.
We are allowed four batteries, each of which has a range of 60 to 100 miles at a speed of 20 mph. In our first race, we covered 67.5 miles at an average pace of 18 mph while switching drivers six times. Our top speed was 26.5 miles per hour. Therefore every sport that involves racing must put the greatest emphasis on safety. A four-point seat harness was attached, and a full-face crash helmet was worn at all times. In a word, that describes our project: there are many alternatives to our concept, some exotic, others simple. You decide, spend your money, and enjoy yourself.

What is needed to make an electric car?
Because of the higher energy density versus weight, modern electric cars largely use lithium-ion and lithium polymer batteries. Lithium, manganese, cobalt, graphite, steel, and nickel are the principal materials needed in lithium-ion batteries.
Can you race electric cars?
Electric drag racing is a activity in which electric cars compete to reach the highest possible speed in a short period of time. They frequently beat gasoline-powered automobiles in races. Certified equipment, such as NEDRA, is used to keep track of records all over the globe.
