AutoBeta(AutoBeta.net)04/26 Report--

The blaze and deflagration of Tesla in Shanghai on the 21st attracted widespread attention. in response to the accident, netizens who claimed to be "parties to the Tesla spontaneous combustion incident" posted a long article describing the situation at the scene of the investigation into the accident.

The car owner released a picture of the battery pack after combustion, and said that the disassembly and inspection found that four groups of batteries were damaged, leaving 12 modules unaffected, each with more than four hundred 18650 lithium batteries.

On April 24, Tao Wei, an automobile defect investigation and appraisal expert recalled by the AQSIQ, said that after testing, it was initially determined that it was a battery short circuit problem, but the car battery and chip had been burned, and there was no way to find the records.

However, shortly after the news came out, Tesla denied the statement and said that further information would be released in time.

On the evening of April 21, a Tesla Model S electric car burst into flames in Shanghai, causing several luxury cars in the garage to be destroyed or damaged. From various angles of surveillance video, the white Tesla car was parked on the parking space, and a lot of smoke suddenly burst out from the bottom of the car. Within 30 seconds, the smoke spread rapidly and deflagration appeared. Tesla and his surroundings were instantly surrounded by fire, and Tesla's car continued to burn.

The 18650 lithium-ion battery used by Tesla Model S is a cylindrical battery, which has a wide range of applications, both in maturity and stability, but it also has congenital safety defects in its structure. A Model S is equipped with more than 7000 groups of 18650 batteries, which is a "small unit, large quantity" mode, so it is difficult to ensure safety after loading and use from a technical point of view, while Tesla's engineers want to reduce the risk. Equipped with a large number of polymer lithium batteries, a liquid ethylene glycol cooling and heat preservation system is designed for the heat generated during discharge and charging.

Before the fire and deflagration of Tesla in Shanghai, there were many accidents of spontaneous combustion, combustion and explosion of electric vehicles in China and around the world, but Tesla S\ X series electric vehicles were not in the minority.

In response to the explosion of Tesla Model S in Shanghai, China, Bloomberg sources said that Musk had said that Tesla would release vehicle fire statistics.

So far, there is no direct evidence to prove that Tesla's car has a quality hidden danger caused by spontaneous combustion.
