    Opinion: Many lessons remain on EV fires
    Listen to this Article

    It goes without saying that an EV should never catch fire, no matter the reasoning, and the recent Ather fire incident serves as a solid blow to already wavering customer confidence.

    That being said, Ather Energy’s immediacy, transparency and lack of finger pointing helps reinforce faith in the company. A preliminary statement was immediately released stating that the incident had occurred and that more information would be shared as soon as possible. Less than 24 hours later, Ather published a detailed account of how and why the fire happened. Meanwhile, it has been 64 days since an Ola scooter caught fire (as of writing this) and we’re yet to hear from the company why it happened. 

    Above all else, this Ather fire serves as a reality check that we have a lot to learn when it comes to EV safety. According to the company, the scooter involved had been in an accident and was taken to the dealership. Here, it was pressure washed to get the dirt off before being inspected for damage. While removing the body panels they noticed that the aluminum battery pack was cracked and that water had already worked its way inside. The scooter was immediately isolated and, as expected, the cells inside soon short circuited leading to the fire. 

    Clearly, battery packs, particularly Li-ion ones, need a comprehensive, well thought out set of safety protocols. In case of an ICE vehicle accident, the vehicle is generally safe to transport once it is established that there are no fuel leaks, the engine has cooled down and the vehicle is fully turned off. With EVs, there can be hidden dangers lurking under the surface.

    First, customers need to be educated, and in case of an accident it’s best to send the vehicle straight to the showroom to be inspected, even if it is seemingly rideable. Second, these products are now advanced enough that they should be able to tell if they’ve had a big impact and, subsequently, alert the company. Ather’s built-in inertial measurement unit, along with its full time internet, should be able to facilitate this. If we have no choice but to ride ‘smart and connected’ vehicles, we may as well reap these benefits.  

    Ather’s statement also mentioned that the scooter had some non-standard screws installed in areas near the battery pack and this could have played a role as well. EVs have left very little for dealerships to do in terms of service, so perhaps it would be wise to have bi-annual mandatory ‘service check-ups’ at a reasonable cost. These can be tied in with the warranty and they will keep things safer for the customer while generating a bit of revenue for the dealer as well.

    The engineering efforts behind the Ather are widely praised and the company says that this is the first such incident in the 150 million kilometres that all its scooters have collectively accumulated. But it shows that freak accidents can happen, and they will only increase as EV adoption grows. 

    Of course, there are far more advanced battery chemistries being developed at breakneck speeds and most will be far more stable. But today’s Li-ion tech will be mainstream for quite a few years to come, so we best learn how to manage these batteries as safely as possible, as soon as possible.

    No vehicle should catch fire, no matter what. That is the ideal scenario and that is the scenario we should all be demanding. Obviously that applies to both EVs and ICE, but clearly EVs are the talking point when it comes to vehicle fires these days. We have already done a separate article on the Ather statement and even in this one we have praised Ather's transparency. This article is not about the statement itself, and anyone who wishes to read it can find it on Ather's various social media pages.

    Appreciate this article, but the opening statement is largely incorrect. Saying an EV should never catch fire no matter what is like saying nothing should ever catch fire no matter what. Despite of Ather giving out detailed account of what has happened, starting an article like this instills fears in consumer's mind. Yes, I do agree that there is a different set of safety protocols need till a robust battery becomes mainstream. According to me an ICE vehicle is far more dangerous in this regard and we have developed a better understanding of it in last 80-100 years maybe? My ask from a reputed auto magazine is to give all the info to the user that service folks pressure washed it, that is blatant error. Also, please post an image of the Ather statement in such article let the user get the complete first hand info instead of interpreted info. let people appreciate the transparency. Whereas no one still knows why an Ola S1 caught fire or for that Okinawa or Pure EV caught fire till govt appointed research results came out.
