Safety of electric vehicles is one concern for many prospective buyers.
While there’s no definitive proof that battery driven cars are any less safe than petrol or diesel driven cars (because each type of car has its own risk profile under different circumstances), there’s a perception that Li-ion batteries are prone to explosion under certain conditions such as high temperature or high energy impact. It is however precisely for this reason that many tests exist (and so do standards & certifications) for the use of Li-ion batteries in automotive applications – Indian standards such AIS 048 for instance is specifically applicable for use of batteries in traction applications. (And AIS 138 is the standard for EV charging)
Regardless of the above, there has been a recent news that Hyundai Kona, an electric car promoted intensely by Hyundai, had exploded in Canada on Jul 26. Now, it is not clear what caused the explosion, as the battery was apparently not being charged at the time of explosion, and nor there appears to be any fire or high temperature item near the explosion site.

It is quite possible that the explosion had nothing to do with the car itself, but such incidents are going to increase the need for stronger safety standards and testing for these, for electric vehicles, especially electric cars.
