Mitchell Weston, chief investigator at the Harris County Fire Marshal’s Office, said that while the batteries are “generally safe”, high-speed shock can cause “thermal runaway,” which is “uncontrolled contact” between various materials in the batteries Batteries caused.
Thermal runaway can lead to fires and “battery reignition” even after an initial fire is extinguished, the security agency warned in its report. Mitsubishi Electric warns that “thermal runaway can lead to catastrophic consequences, including fire, explosion, sudden system failure, costly damage to equipment and possible personal injury.”
The firefighter’s office investigated the fire in the crash, a spokeswoman said. Constable Herman said his department was working with federal agencies to investigate.
He said police officers contacted Tesla on Saturday to “advise on some matters” but refused to discuss the nature of the talks.
Tesla, which has disbanded its PR team, didn’t respond to a request for comment.
Elon Musk, Tesla’s managing director, had published a recently released safety report from the company on Saturday and wrote on Twitter that “Tesla is busy with autopilot and is now approaching a ten times lower chance of an accident than the average vehicle”.
Tesla, which describes autopilot as the “future of driving” on its website, says the feature enables its vehicles to “automatically steer, accelerate and brake in their lane”. However, it is warned that “current autopilot functions require active driver monitoring and do not make the vehicle autonomous”.
In 2016, a driver in Florida was killed in a Tesla Model S who was in autopilot mode and unable to brake for a tractor-trailer that turned left in front of him.
