Why Can’t an Electric Car Charge itself While Driving

Most electric car owners are of the opinion that their car should charge itself while driving since they recycle some energy while driving.

The truth is that energy conversion in electric cars isn’t 100% reliable and they also lose some energy during the conversion process in form of heat.

In addition, some electric cars have the ability to recycle some energy using regenerative braking (where braking is often required – racing vehicles)

Despite all this, an Electric Car can’t charge itself because it doesn’t have a technology that will recharge its battery on the go. Technologies such as solar panels that’ll recharge your electric car while you’re on the road.

In this article, I’ll further give reasons as to why an Electric Car can’t charge itself while driving and technologies that’ll help them achieve this.

Why Can’t an Electric Car Charge Itself While Driving?

Electric cars can charge themselves while driving because they make use of the energy that has been stored in the battery while on the road and without the aid of charging technology, they won’t be able to charge themselves.

While most cars also have the ability to conserve some energy using regenerative braking, this energy can’t power the car.

Regenerative braking is more efficient on a track that requires frequent braking such as F1 racers. It utilizes the kinetic energy of the car while braking and converts it into electricity which is stored in the battery for future use.

As of the time of publication, there’s no available technology that allows electric cars to charge themselves while driving but hopefully one will be out in the nearest future.

So, for now, you’ve to settle with charging your electric car at the nearest approved charging location or destination.

Technologies that Allow an Electric Car to Charge Itself

Just like your mobile phone that works with stored electricity in the battery, and won’t charge itself except solar technology is built into it; that’s how electric cars work.

Electric cars are meant to consume the energy supplies from the battery while trying to regenerate some through braking but this saved energy won’t be able to serve for long.

The two available technologies that’ll allow electric cars to charge themselves while driving are solar panels and regenerative driving.

Continue reading to see how they work.

1. Installation of Solar Panels

Solar panels will work fine if employed to charge an Electric Car while it’s on the go but car manufacturers don’t promote this.

And the reason why they don’t is that one solar panel won’t be able to charge a car because of the difference in capacity/ENERGY.

Also, the roof doesn’t provide enough space to house many solar panels and even if you do get the solar panels to the roof, they have a charging rate of 25%.

This implies that your car’s battery will not be fully charged and won’t take long because it runs down.


2. Regenerative Braking

If you reside in urban areas or are into motor racing then regenerative braking should help in conserving some of your battery energy.

Regenerative braking helps in converting some kinetic energy of the car into charge during braking.

This charge or electricity will be stored in the battery in a usable state until when it’s needed.

So, you’ll only benefit from this when you brake quite often, however, the energy will start to disperse once the brakes get hot.

Regenerative braking is often effective in hybrid cars and may not work fine for electric vehicles.


Why don’t electric cars charge themselves when driving?

The reason why electric cars don’t charge themselves when driving is that electric cars use already saved battery while on the go and the infrastructure that supports self-charging isn’t available yet.

Will electric cars be able to charge while driving?

No, because the infrastructure that allows self-charging on an Electric Car isn’t available yet.

Why can Tesla’s charge themselves?

Tesla actually charges itself using regenerative braking which converts kinetic energy into electricity to be stored in the battery but this saved energy doesn’t have the power to fully charge an Electric Car.
