How it started

How it started

EV catching fire cases blow up with the introduction of Li-ion batteries. However, back then it didn’t come into the limelight due to fewer cases.

When 'EV fire' go mainstream

When 'EV fire' go mainstream 

One fine day, Ola electric scooter caught fire and this news got viral on social media. The questions started raising among the whole EV community as Ola is considered the best in the EV market.

What really happened

The incident took place in “Pune” when the scooter was standing still on a sunny day. And suddenly its battery exploded following a huge smoke.

The after story

The after story

After the Pune incident, the whole EV ecosystem was being doubted, and people even started social media campaigns against electric vehicles.

However, the matter is forgotten after few days.

But problems not over yet

But problems not over yet

Still, the question remains the same, why the EV batteries do catches fire.

Understanding the battery

Understanding the battery

A battery is nothing but a small object that’s filled with humongous energy, enough to run your house for the whole day in a full load.

So, What?

So, What?

It directly implies how dangerous it would be if such a huge amount of energy is released in less than 5 seconds. That’s what happens in thermal runaway.

Some technicalities

Some technicalities

The battery is mainly made of three components, Anode, Cathode, and a thin membrane. In a normal battery, the electricity would flow from anode to cathode, via a thin membrane slow and steady.

Where’s the problem

Where’s the problem

Now as you could see the main problem is in the membrane. In the race to increase the energy density, everyone is reducing the membrane size and thickness. It’s really bad.

What happens when a battery explodes?

What happens when a battery explodes?

Due to puncher or any other way, the thin membrane gets harmed and in a battery with 1000s of cells if even a single cell’s membrane gets punchers it creates a chain reaction (thermal runaway).

How a battery explodes

How a battery explodes

As the membrane puncher, the anode comes in direct contact with the cathode that emits an enormous amount of energy in a very short interval of time, and following the chain reaction the battery smoke itself up in no time.

The real Reason

The real Reason

Hence, the actual reason for battery explosion is the sudden discharge of all the energy inside a battery.

How you can prevent this

How you can prevent this

You can’t! of Couse, you should save your li-ion battery from any kind of physical damage but if your battery is made according to other country conditions you can’t do anything about it.

Conclusion

Conclusion

So, finally, we can conclude that the batteries should have a hard casing or a thick membrane to avoid battery explosion in E.V.

A key Take away

A key Take away

Right now, the Indian EV industry India is going through a learning phase, and making mistakes must be allowed in the learning phase.  But, India will grow and no doubt, just like software India will be the largest exporter in the global EV market.
