Between 2012 and 2019, many cases of Tesla battery fires were relayed in the press. However, it is certain that others have never attracted the media, and all have, in general, were subsequently analyzed directly by the manufacturer, only in-house.
According to an article Los Angeles Times, the National Traffic and Road Safety Administration asked Tesla to produce all relevant documents "High voltage battery fires that are not related to a collision or battery damage", whether on its Model S and Model X.
An investigation on Tesla batteries
The purpose of this study will be to determine the nature of the different fire starts that were experienced by each Model S or Model X fire victim. NHTSA actually wants to know more about these fires, to see if subsequent updates by Tesla were needed.
It must be said that after the fire of a Model S last May in Hong Kong, Tesla has deployed an update losing autonomy to each copy, for "Protect the battery and increase longevity". Unfortunately, the model's customers had not responded well, especially since their car – bought at around $ 100,000 – had lost a strong resale value.
Thus, NHTSA will seek to establish a link between the fires encountered on certain models, and the solutions found by the brand in its updates. To do this, the administration calls Tesla to produce documents of "All original elements written, printed, typed, recorded or graphical, of any nature … of all types, descriptions", to be able to draw up an assessment of the misadventures of each battery burned in the world.
For its part, Model 3 is not affected by the case. It must be said that his batteries do not present the same way. Its battery system differs from that of Model S and Model X, as does its liquid cooling system.
