An e-scooter S1 Pro made by the OLA company has caught fire in Pune.

e-scooter: There have been at least four times when two-wheeled vehicles that use lithium-ion batteries have caught fire. Li-ion batteries: What are they, and how do they work, and what are they used for?

What caused these cars to start on fire?


During the last five days, there have been at least four reported cases of two-wheeled electric vehicles, such as those made by Ola, Okinawa, and Pure EV, suddenly bursting into flames. This has brought up safety concerns about these vehicles, especially the batteries that power them.

EVs are powered by lithium-ion batteries, which are the same kind used in cellphones and smartwatches. They are thought to be more efficient and light than their predecessors. The fires that have happened recently show that they could also be a fire risk.

These batteries are made of lithium ion, which is a type of metal.
Most of the batteries that power today’s consumer electronics are lithium-ion (Li-ion) batteries. These batteries are found in electric cars, smartphones, and laptops. An Li-ion battery has an anode, a cathode, a separator, an electrolyte, and two current collectors. Lithium is stored in two places: the anode and the cathode. The electrolyte moves the positively charged lithium ions from the anode to the cathode and back through the separator. The movement of lithium ions makes free electrons in the anode, which makes the positive current collector have a charge at the end of the wire.

A Li-ion battery is better than other types because of its light weight, high energy density, and ability to be recharged. It’s better for things like electric cars and phones because it can be recharged. Li-ion batteries, on the other hand, usually have a longer life than lead acid batteries.

In general, a Li-ion battery can store 150 watt-hours per kg, which is more than double the amount of watt-hours that a lead-acid battery can store. In simple terms, this means that Li-ion batteries are more efficient than other types of batteries while keeping the size of a product about the same. This means that an electric car with Li-ion batteries will have a longer range and smartphones will last longer through the day.

However, one of the main advantages of Li-ion batteries is that they have a lot of energy. This could be the battery’s downfall. Batteries made by two-wheel EV maker Ather Energy say that their high energy density makes them unstable in certain situations, which makes them less effective at running things like the brakes and the lights. They work best when they stay within a safe range. There is a battery management system (BMS) that is put on a Li-ion battery to make sure they work properly.

A battery management system is a tool that helps you keep track of your battery.

A BMS is an electronic system that is connected to all of the cells in a Li-ion battery pack, and it always checks their voltage and the amount of current that flows through them to make sure the battery is safe. A BMS also has a lot of temperature sensors, which give it information about the temperature in different parts of the battery pack. All this information helps the BMS figure out other things about a battery pack, like how quickly it charges and discharges, how long it lasts, and how efficient it is.

So, why did the batteries of the Ola, Okinawa, and other electric cars start to get hot and then start to melt?

The real reason why the Ola and Okinawa EVs caught fire isn’t known yet, but the companies say they’re looking into it. That’s not what Okinawa said. It said that from “credible sources,” the media, and local authorities, it found out that the fire in its scooter was caused by “negligence in charging the vehicle.”
They also serve as a warning about what can happen if there are problems with Li-ion battery packs. According to experts in the field, there could be a number of reasons why these batteries could catch fire. These could include manufacturing flaws, damage from the outside, or problems with the BMS.
Temperature, on the other hand, can be tricky in a Li-ion battery pack. As a representative of an electric vehicle manufacturer said, “While Li-ion batteries are better at working in warmer temperatures, extremely high temperatures could cause the battery pack’s ambient temperature to rise as high as 90-100 degrees.” This is when the batteries are very likely to start a fire.

Also, electric cars and other devices have a battery pack that has hundreds of batteries inside of it. A fire can start even if just a few Li-ion batteries fail and start a short circuit. Because a battery pack is tightly packed with many Li-ion cells, this can start a chain reaction. This is called a “thermal runway,” and experts say it’s why Li-ion batteries start to catch fire right away.

If the battery pack was damaged in an accident, it could also catch fire after a few cycles of charging. This isn’t the only thing that could cause this.

He said that manufacturers aren’t taking enough time to design their products and that government testing standards may not be enough to test all real-life situations. Tarun Mehta is the founder of Ather Energy.

This is what people have said about the fires.

The Ministry of Road Transport and Highways has asked the Center for Fire Explosive and Environmental Safety (CFEES) to look into the sudden fires of the vehicles. The CFEES has been called in to help with the investigation.
There have been fires caused by faulty Li-ion batteries in the past.
There have been a lot of times when devices or vehicles that use Li-ion batteries have caught fire. There are two examples that stand out: Samsung’s Note 7 and a Tesla Model S that caught fire while it was in a parking garage in Shanghai.

There was a fire in a Tesla car that was caused by a single battery module that was in the front of the car. The company said that its investigation found no other system flaws.

Many of Samsung’s phones in the Note 7 series caught fire because of manufacturing flaws. In some cases, the battery insulation tape was missing, which caused short circuits; in other cases, sharp protrusions inside the cell caused damage to the separator between the anode and cathode.
