ABS or anti-lock braking system is so common these days, it's almost standard. Is this system also beneficial to Electric cars? Check it out!

Are you wondering if it is a good option for Electric vehicles (EV) to adopt ABS? Are you just clueless about what an ABS car is? Or are you only seeking to expand your knowledge on automobiles enabled with the ABS module? Do you say out loud: Is ABS a good option for EV? Finally, do you think: what does ABS stand for in a car? Say no more! Provided in this piece are reasons which should fetch answers to all the throbbing questions that concern ABS and EV.

If you are willing to unravel the top of the line benefits and disadvantages that come with the ABS function, read on!

Before we explore what ABS functions are, it’s quite appropriate to define in clear terms what the seemingly hard to crack terminologies are. Without further ado, let’s get to it!

What is an EV?

EV is an acronym, a short form for Electric vehicle. The first EV car was manufactured in 1890. The succeeding EVs steadily advanced, introducing new updates as they went. Currently, EV vehicles can be classified into either partial (hybrid) or fully electric powered. The major difference is that the latter one runs entirely on electricity and the hybrid could run on a combination of petrol and electricity, which gives it an advantage for long-distance travel.


Electric vehicles may be either hybrids or fully electric

So! What is ABS?

Yeah, what exactly are anti lock brakes? ABS is an acronym that really means Anti-lock braking system, which is an anti-skid braking system. This technology was designed and developed for automobiles to help enhance safety during sudden or emergency braking.

After the manufacturing of the early land vehicles, it was noticed that whenever a driver was forced to make hasty and unplanned braking the car wheel would automatically lock in a particular direction. The driver, no matter how skilled, would be unable to change the direction of the vehicle. This is often disastrous especially when the wheels are locked in a heading towards buildings or people. At this point,  ABS manufacturers decided to step in and provide a solution to this issue.

How does an ABS system work?

Yes, I know what an Anti-lock Braking System is, but how does it even work? If that was your question, then worry less! You probably need some insight into what the ABS layout is and how it really executes its duty to ensure safety. So, here we go!

Let's spare a technical look at how this wheel lock occurs, what goes into a lock, and of course how ABS was designed to prevent it. The non-regulated degree or volume of braking force, also referred to as brake force distribution, required to bring the car to a safe stop is very responsible for the wheel locking. Sometimes this braking force is just too much. This makes the hydraulic pressure, which is distributed to the wheel in bringing the wheel to stop, to also lock the wheel in a certain direction. This lock remains until the pressure is removed.

Although cadence braking is one effective way of reducing the effect of skidding especially on a slippery surface, there still was a need to put in place a system like the electronic brake force distribution which would automatically detect and regulate the amount of hydraulic pressure which would be sent to the wheels. Traction control system is another safety measure that is similar to ABS and serves to control the individual spin-speed of a wheel through braking. You could also say ABS works like a Combined Braking System, which syncs the braking operations on both front and back tires.

What if ABS goes bad?

An operative ABS system could also regulate car speed. When the ABS system goes bad there is a high tendency of moving uncontrollably! So how could you timely detect the abnormalities and know the signs you should be looking out for? Here is how!

Every car with an ABS system has an ABS module, which is a control unit that gauges the wheel speed by using the data sent by the ABS sensor. It in turn regulates the amount of hydraulic pressure to the wheels. This system relays certain signals if it goes bad. Some signals are easy to spot considering it’s an automated system.


As useful as an ABS system can be, it does develop problems too

These common problems could erupt from any component of the ABS system

1. ABS sensor symptoms 

This part of the whole system is quite important as it measures the speed of your vehicle and relays the data to the ABS system. If it goes bad, which means it can no longer measure and relay data to the system, you will often experience wheel locking and lots of skidding for the whole braking distance.

2. ABS control module error

A microprocessor that controls how much and when to supply hydraulic pressure to the braking system. Since it acts as the brain, if it goes wrong you can always expect that your wheel would lock.

Vehicles that are enabled with the ABS system often come with the ABS warning light that comes and stays on to indicate when your ABS system is non-functional. Whenever you see this abs light on car pop up on your dashboard, know that your vehicle might not be safe. The brakes would work but won’t be automated to keep you from skidding. Cadence braking could be your alternative.

3. Upgrading your car brakes wrongly

From knowing the advantages presented by using an ABS enabled car, a lot of you cars owner would want in on this advantage and most time would try to upgrade your car brakes to ABS. It is very possible to upgrade some variety of cars with ABS however, upgrading also comes with its own conditions. It is most advisable to consult mechanics on how to successfully upgrade your brakes. You could upgrade it wrongly and be left with a system that is just problematic.

EV and ABS

Without a doubt, you know now what an EV is and what an ABS is! The relevant question now would be about the compatibility of both. Can or should an ABS work on an EV? The purpose which ABS sets out to accomplish is undoubtedly good. So, can it bring about that same objective to an Electric vehicle?

Electric vehicles are built with a good traction control system. In recent times, Electric vehicles are built with enormous speed to cover great distances. However, not all are built with the ABS module, which was majorly designed to help bring a running vehicle to a successful stop.

By understanding the functionalities of the ABS system we can deduce that it will be a very unattractive sight for a driver to suddenly lose control of the wheels.

Is ABS good for EVs? An absolute yes would be the answer as this admirable braking system of a land vehicle is to stop the vehicle or reduce its speed as fast as possible, while maintaining the direction and stability. Electric cars, though usually high on tech, also require this assistance when braking on highly volatile roads.
