While some see a recent string of three battery fires involving Tesla Motors’ Model S electric sedan as nothing more than unfortunate happenstance, the National Highway Traffic Safety Administration (NHTSA) is delving deeper into the matter, seeking detailed records from the two fires that occurred in the United States. The NHTSA, in a letter to Tesla, is seeking a detailed description of all possible outcomes of a debris strike to the Model S battery pack, plus any limits inherent in the design in regard to fire control and damage tolerance. The NHTSA is also seeking any information on design or material changes planned or already made to prevent further similar fires. On top of that likely mountain of engineering data, the NHTSA also wants Tesla to turn over records from the vehicles involved in the fires, owner information, and certain internal communications on the matter.
