Tesla CEO Elon Musk has explained the Tuesday's accident of Model S electric car in which the battery caught fire. He defended the safety performance of electric cars. He stated on the Tesla's official blog post that "you are 5 times more likely to experience a fire in a conventional gasoline car than a Tesla!"
Musk has issued the explanation statement 3 days after the accident. Tesla shares drops more than 6% a day after battery fire. But Elon Musk says that the fire risk is 5 times lower in Tesla than a conventional gasoline car. He said, "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."
So what is happened with Tesla Model S battery that blazed in accident? Musk said that a large metal object that fell off a semi-trailer struck under the car with a peak force. It makes a 3 inch hole in quarter inch thick base armor plate. This collision results in battery fire but only in the front module out of total 16 modules internal firewalls within battery pack stopped it spreading in whole battery.
Fire flames were directed towards road due to vents built into the battery pack and keep these away of the vehicle. The driver remained unharmed due to this. "It is important to note that the fire in the battery was contained to a small section near the front by the internal firewalls built into the pack structure. At no point did fire enter the passenger compartment," said Elon Musk. "The Model S owner was nonetheless able to exit the highway as instructed by the onboard alert system, bring the car to a stop and depart the vehicle without injury," he also said. The semi-trailer road crew saw the whole incident and they "appears to be the culprit," according to Tesla CEO.
