2018 First case of electric vehicle self-ignition: Tesla battery system fires spontaneously

Unsurprisingly, the fire of the self-ignition of the first electric car in 2018 was ignited by Tesla.

Last week, a residential building in a second-floor garage in Chongqing, a Tesla Model S spontaneously ignited when it was not charged and was not collided. Because the fire-fighting facilities in the community were relatively in place, the smoke detectors detected alarms after the fire, and the heroic community property personnel rushed to the scene the first time to control the fire.

The following is the site picture.

Compared with the previous Tesla combustion accident, the incident of spontaneous combustion from the scene shows that there is no such thing as "collision," "slap," "overcharge," and so on. The accident car is so quiet and quiet on the second floor as a The beautiful man, the result almost became a roast suckling pig. From the standpoint of the auto-ignition vehicle, the interior is in good condition and the ignition point is at the bottom of the vehicle. The battery system should be on fire.

The power battery of Tesla's electric vehicle is made up of thousands of single 18650 three-element lithium batteries provided by Panasonic. Although its BMS (battery management system) is very powerful, the stability of the three-element lithium battery is inherently relative to BYD. (64.800, -0.34, -0.52%) lithium iron phosphate batteries will be much worse, even if Tesla has adopted a reinforced safety protection design such as outer shields, cooling systems, but it is still difficult to completely avoid Tesla The accident of spontaneous combustion of an electric car occurred.

Since its launch, Tesla’s popularity has been accompanied by various accidents. Among them, there are both collision accidents caused by defects in the design of automatic driving systems and combustion or spontaneous combustion caused by external or internal causes.

Occasional accidents did not extinguish consumer and investor confidence in Tesla's electric cars. In 2017, Tesla's global sales exceeded 100,000 for the first time, an increase of 30% compared to the same period of last year. At the same time, Tesla’s share price also rose by 45.7% in 2017, its market value surpassed that of GM and Ford, and became the largest US value-for-money and fourth-largest automobile group (after Toyota, Volkswagen and Daimler).

Judging from the current situation, the biggest problem faced by Tesla's development is not security, but is limited by capacity. In particular, the Model 3, which was sold at a starting price of $35,000, has been sought after by consumers all over the world. However, Tesla's delivery speed, which is limited by capacity, is far behind the market demand.

Although from the current situation, the overall performance of Tesla electric vehicles is still the best among the mass production vehicles, but this spontaneous combustion accident once again sounded a warning to Tesla: Safety is the bottom line and premise of automotive products.

Here, it is hoped that Tesla will seriously review the safety issues of its products, in particular whether the first batch of Model S has the defect of battery design that requires recall.
