Tesla CEO says fire caused by impaled battery

The CEO of electric car company Tesla said on Friday that a battery in a Model S that caught fire this week was apparently impaled by a metal object.
Elon Musk gave more detail in a blog post about the fire that became an Internet sensation and unsettled Tesla investors. He also defended the car’s battery technology.
Musk wrote in a blog post on Friday that fires are more common in conventional gas-powered vehicles.
“For consumers concerned about fire risk, there should be absolutely zero doubt that it is safer to power a car with a battery than a large tank of highly flammable liquid,” Musk wrote.
The CEO said a curved metal object on the road was apparently to blame for the fire Tuesday. He says the large object’s shape led to a powerful hit on the underside of the vehicle, punching a 3-inch hole through an armour plate that protects the battery under the passenger compartment.
