On June 27, a Lifan new energy car suddenly caught fire in a parking lot located in the north of Hangzhou city. On June 28, a new energy car caught fire in a garage in Hangzhou, and reports say that the new energy car was so badly burned that it was impossible to distinguish its specific model from the relevant video.
Similarly, such accidents have occurred in Tesla, it is understood that the Tesla Model S spontaneous combustion incident has not yet received a reasonable official explanation, only some people believe that the Tesla side or the existence of battery cooling system design defects, easy to make coolant leakage into the car's battery pack, resulting in the possibility of spontaneous combustion of the vehicle.
According to foreign media for the Tesla Model S spontaneous combustion event has found the cause. The report shows that Tesla in 2012 when the first batch of Model S, Tesla side has known its battery cooling system design defects, easy to make coolant leakage to the car's battery pack, so that the vehicle may appear spontaneous combustion. Although Tesla had been looking for a solution before putting the model S into production in 2012, the defective vehicles were not fully resolved by Tesla in the end in order to deliver the vehicles in time.
Reports mentioned leaked emails show that Tesla has commissioned three companies (IMR Labs, Ricardo Consulting and Exponent) to test and investigate the battery cooling system, and the three companies respectively in July and August 2012 to Tesla gave the relevant test reports, the three results show that its end connection fittings have problems.
According to the relevant survey data, new energy vehicles spontaneous combustion fire in the distribution of factors, including battery problems accounted for 58%, 19% of the collision problem, 7% of the problem of water immersion, 7% of the use of the problem, parts failure 3%, 3% of external causes, other 3%. In the face of spontaneous combustion of new energy vehicles, battery problems or spontaneous combustion potential concentration point.
In addition to the heat and other external factors related to new energy vehicles spontaneous combustion, with the new energy vehicle battery pack, new energy vehicle age, the car wiring and circuit board, in addition to the new energy vehicle charging environment and charging pile quality also has a certain relationship, of course, the battery thermal management technology of car companies is also the focus of the problem, which may also be many new energy vehicle enterprises face technical problems.
Into the summer, new energy vehicle fire events have also become the focus of consumer attention, which in terms of car consumers should pay more attention to the process of using the car to kind of car good car habits can also reduce the probability of spontaneous combustion, first of all, regular maintenance can not overlap, followed by charging time not too long, the third to pay attention to safe driving to avoid collisions.
