Tesla catches fire and spontaneous combustion, The safety of ternary battery needs to be improved

Release time:2022-07-28

  On July 22,a Tesla Model X crashed into a telephone pole in Taiwan and caught fire.Fortunately,no one was injured.


       Pictures from the scene showed that the front half of the vehicle had been completely damaged,apparently by a burning battery pack.The battery pack combustion can be divided into short circuit,charge and discharge overload and high temperature.Combining with the field conditions,it can be judged that the battery pack overfire is caused by short circuit caused by impact.

  In the acupuncture experiment,the NCM battery caught fire,while the LFP battery only smoked after acupuncture.


  This is because lithium iron phosphate is more resistant to high temperature than teradic lithium.The thermal runaway of lithium iron phosphate is about 800℃,while the thermal runaway of teradic lithium only needs 200℃.


  The NMC battery in the accident was the main cause of the fire after the accident.
