Really sketchy details in article. Basically they asked a fire fighter and they guessed. On the other hand, almost every electrical fire will be due to a short. It may not even have been in a vehicle, it could have been a wiring fault before the evse.
Also, comparing that pile of vehicles to north american ev's is inappropriate. The vast majority of those in the fire (and maybe all) would never be approved for use here.
"As many as 30 new e-rickshaws, 50 old e-rickshaws, 10 private cars, 2 scooters and a motorcycle were gutted"
It almost reads like an article written by a bot. It raises points about dc fast charging (likely not applicable to most of the vehicles in the fire), static electricity, etc. Pretty much a shotgun blast of random ideas.
