Emergency crews need more info on EV risks

Perhaps nothing illustrates the complexity just like the deadly Mountain View crash, one already acquainted to NTSB investigators as a result of the board had probed the function Tesla’s Autopilot performed within the crash.

After arriving, Tesla’s engineers tried to examine battery parts, however popping sounds once more emanated from the battery, based on the report. They determined it was too dangerous to additional analyze the car alongside Highway 101.

Authorities wanted a flatbed to keep away from additional stress on the car structure. But it was metallic, in order that they propped the Model X on wood blocks. Six hours after the crash occurred, a hearth truck escorted the flatbed from the scene and alongside an hourlong, uneventful experience to an impound lot.

When the Tesla engineers arrived, they underscored the significance of leaving a 50-foot radius across the car. That was impractical, so the employees “did the best they could,” based on the report. Twenty minutes later, a California Highway Patrol officer heard popping sounds coming from the Model X, and the San Mateo Fire Department was summoned. Forty-five minutes later, they had been known as once more. The battery had reignited.

Five days after the crash, the battery ignited one final time, and firefighters arrived to search out flames 8 to 12 inches excessive.

“For me, that one was really eye-opening,” Barth stated. “The fire department had access to the engineers, and there was still confusion about how to handle this vehicle and the attempts to remove the stranded energy; they were not able to do it effectively. That pointed to the fact that, ‘Hey, this stranded energy, there’s still gaps in the regulatory approach.’ ”

Despite the presence of two fireplace departments acquainted with electrical automobiles and two battery engineers from the car producer, the answer proved vexing, the risks resilient.
