What causes electric cars to ignite?

Another burnt electric car on Tesla happened just a few days ago in China, where model C inflamed underground parking and then exploded. Luckily, no one suffered, but in an accident earlier this year, with the model C, the driver did not come out of the car that ignited, and he burned.

But why are such incidents happening? Are electric vehicles so dangerous? The answers to these questions are trying to give the Auto.mail edition, using the views of experts and dealers of electric cars. They say Tesla's cars are burning for various reasons, not just because of the same problem.

The first cases were almost 6 years ago

In 2013, the first burnt Tesla was fixed, in this case a metal part of the towing device was guilty. It hits the bottom of an electric car and damages the battery below the floor. After the second such case, Tesla engineers took control of the pneumatic suspension, the purpose of which is not to reduce the clearance of the ground at high speed. The battery case is reinforced and has special protection.

Sometimes the reasons for the fires – like those in Shanghai a few days ago – are inexplicable. Tesla sent a team to China to investigate the case. A similar incident, but with the Tesla Model X, was in February in Vermont (USA). Then, a completely burnt crossover was found on the frozen lake. It turned out that the owner had followed the fish and hit a stone, and then his car began to make strange sounds and set it on fire.

What are the tests for accidents?

Obstacles are the most common cause of Tesla burning. Laboratory tests, however, show that this type of car is the safest. Tesla is at the head of the National Traffic Safety Authority (NHTSA). The only problems with them were the roof and airbags, but on the recommendation of the experts, they were removed.

The American IIHS and the Australian sub-division of the NCAP tested 42 hybrids and electric cars that showed greater performance than standard internal combustion engines. In any case, IIHS succumbed to a special observation of the tested machines, which lasted for 2 weeks. During this period none of them did not brighten out.

However, this happened with one of the prototypes of NHTSA. The hybrid Chevrolet Volt was tested with a side impact, then went to the car's parking lot. Three weeks later, it was lit and burned.

The human factor

Why are motorists burning in real traffic accidents? Tesla is firmly convinced that in February the incident in Florida is blame for speed. The driver moved too fast, he lost control and hit the tree near the road. It is not clear whether he used the autopilot. Another question is why firefighters failed to open locked doors and the driver set it on fire.

For now, Tesla Model S is a leader in the fires, which is explained by the fact that about 300,000 units are sold by the electric car around the world. The fact is that the S model is the first brand of a brand that is so widely distributed, and that's the problem to be removed on the go. However, the company thoroughly examines every incident and attempts to immediately remove the defects.

With the new model 3, there are no fires yet. In March, on a motorway near Los Angeles, Nissan Sentra hit a fast electric car that fully ignited and burned. Tesla herself sustained herself, was corrected, and returned to work.

Meanwhile, former Tesla engineers told CNBC that most of the mass-produced batteries of the brand are manually collected by Panasonic, a battery-powered company. It's the production problems of the Tesla Gigafactory 1 battery factory that have delayed the launch of Model 3. Battery production leads to more marriage and makes these elements potentially dangerous, former Tesla workers say.
