Recently, tesla MODEL S and colourful come ES8 early or late the high attention that spontaneous combustion incident caused social all circles again, fire cause still is in further investigation, tesla government also is responded to say, already sent personnel to be driven toward the spot. After this, colourful comes ES8 also produced similar problem, the government also made a response to combustion incident, but belong to high end relatively because of two models electric car, make the consumer of car of a lot of new energy resources generated doubt again to the safety of car so. We talk about car of new energy resources to be installed after all today insecure.
Above all, all of us knows traditional fuel car and pure electric car are put in the likelihood of spontaneous combustion. Because photograph of pure electric car compares traditional fuel car to be in batteries and circuit respect are more complex, the demand to the technology is higher also at the same time, the scale that brings about spontaneous combustion of pure electric car wants relatively a few taller.
Next, we look from the cause that causes spontaneous combustion of pure electric car. 1, the car is in travel process, as a result of the action of air air current, batteries is in medicinal powder hot condition, when car flameout when, medicinal powder hot system also quits the job, the temperature that the quantity of heat of inner self links external environment is exorbitant, bring about high temperature to cause inflammation. 2, also be to suffer environmental temperature effect, dynamical cell is installed for the most part in car bottom, when summertime high temperature, ground radiant is many quantity of heat, be absorbed by batteries group, again with other overlay of a few reasons, the cell that creates vehicle likely heats up out of control, cause combustion accident then. 3, the quality reason of batteries itself, the difference between the monomer batteries with good quality is lesser, conversely bigger, also put in hidden trouble.
Finally, see safety from inside data. Have data statistic, china sold car of about 1.256 million new energy resources 2018 (among them pure electric car 984 thousand) , in the meantime, achieve more than cases 40 up to the event of electric car on fire that produced on October 21, 2018. The reason of on fire of motor-car of major pure report, compare with spontaneous combustion photograph, be in the majority with collision on fire. As a whole, of car of new energy resources or special safety, although exist an exemple, but the progress as the technology, accident occurence rate is sure smaller and smaller.
