Coincidentally, it was during one of the hottest days of summer that is kindled a Tesla Model S. The incident took place at Bayonne August 15 2016: it is a new episode of a long series for the American car to all-electric propulsion whose mysteries inspired many beliefs.
Let’s start by recalling that just park on a herbé aisle with any car a little low to fire it. The vehicle does not suffer any fault, it’s just that he has been led to pace (for example on the track or uphill, hitched to a trailer). Contact dry grass with a hot muffler enough to ignite
Point this kind of accessory on a Tesla. As purely electric-powered car, it does emits no exhaust gas. Its engine will also maintain any sort of combustion, since it is a simple electromagnetic field that causes rotation of the wheels. This electric motor can heat up, especially when the ambient temperature exceeds 35 ° C as was the case on August 15 in Bayonne. Nevertheless, the source of more heat on a Tesla – like most electric cars – battery remainder of current batteries
The question of the influence of high temperatures is a matter of. People chat on forums devoted to electric cars in general and Tesla in particular. Most of the questions revolve around the loss of autonomy that results, as inevitable in summer and winter. The computer that controls all Tesla cars system is programmed to trigger the action of cooling fans and keep cell lithium ion in a predefined temperature range. At this point, the Tesla are more advanced than the Nissan Leaf, for example.
the batteries Batscap lithium-metal-polymer Bolloré that power electric cars in self-service Autolib ‘in the Paris region and Citroën E-Mehari is a case apart: they consume a significant portion of the current in them to keep at the right temperature. So that a few days they are running if they are not connected to the sector.
Batteries and finger pointing Supercharger
The battery lithium ion Tesla is maintained at the right temperature by the circulation of a glycol-based solution in a radiator where it is discharged of its calories in contact with a pulsed air. These are the calories that likely caused the fire first reported a Tesla Model S in 2013. In contact with the intense heat, synthetic material that lines the bottom of the trunk before melted then s is consumed, setting fire to the entire front and the rest of the vehicle.
It seems conceivable that a leak of this overheated coolant can potentially ignite vegetation under the car stopped. Although this remains unproven. Such leakage could be caused by the raising of the debris passing car: it would damage the radiator or a pipe. In February 2013, it is likely that the mishap was the victim Tesla went up in smoke on a state highway in Washington. Note that in the case of the Tesla Model S Bayonne, the driver told hearing “ a loud noise in the car ” on a “ small acceleration “on a boulevard.
in March 2014, Tesla Motors decided to strengthen the foundations of the Model S with three shields aluminum and titanium facts . Of movies directed by him showed that using this shield can resist shocks inflicted by a concrete block or steel hitch. In addition, the Model S software was modified remotely to take a little care-to-ground of the vehicle as it travels beyond 80 km / h. Aerodynamic efficiency loses that driving safety wins.
A burning car are not interested in newspapers. Unless there is an electrical
At the same time, the American manufacturer complained that the fire of two of its models concern the media more sensations that some 200,000 flare conventional vehicles listed in 2013 in the United States . But if the public is conceivable that a shock can damage a car, it is concerned that the Tesla Model S will be inflamed stopped during the charging phase of their battery.
On think of this view charred remains of a Model S on a bed of snow in Norway in January 2016. Its owner had connected to a Supercharger, one of the famous ultra fast charging stations developed and installed by Tesla Motors. Both the American manufacturer readily acknowledges that a shock could cause a fire starting (although the risks appear lower than a gasoline car), so he rejects the idea of a possible failure of its Superchargers .
Proof by contradiction: in November 2013, the Tesla, which caught fire in his garage in Irvine, California was not related to a Supercharger but at a “slow” charger. Following this incident, Tesla Motors took the initiative to distribute to its customers new adapters, this essential link between the Tesla charging cable and taking traditional current. In December 2013, a software update was designed to eradicate risk of overheating at the outlet .
What to conclude from all this? Look at millions of kilometers, the Tesla is not dangerous car; they do not tend to ignite more than average. The investigations conducted by both the manufacturer and by the police authorities in the cases cited above have not yet updated any security breach. For now, it is the same in terms of the suspected failure of the obstacle detection system and helps maintain online Tesla Autopilot, implicated in the death of an American in the month of June.
