On May 12, the circumstance that the tesla Model S that a park of Hong Kong is in a parking lot was not charging finishs abrupt on fire, fireman was used fully put out a fire of success of 45 minutes of ability, and be in batteries explosion appeared 3 times when put out a fire.
This has been the event of the 3rd spontaneous combustion that near future tesla produces, model S of a tesla of Shanghai left a garage in the ground on April 21 abrupt spontaneous combustion explodes, rapid ignition 3 cars on the side; On May 3, model S of a tesla in one private garage produces san Francisco spontaneous combustion. Besides, on April 2, xi'an colourful comes an ES8 produces accredit service center combustion, accident car by complete burn down.
Actually electric car spontaneous combustion is not the near future happens again and again only, just be driven course of development, automatically to wait for heat topic place to mask by boat of electric car add, add upside to divide car look forward to to be able to undertake crisis public relations, incident of spontaneous combustion of motor-car letting report looks to be like and be done not have so frequent.
The prime cause of electric car spontaneous combustion depends on the hot out of control of batteries, will simply tell basically have 3 kinds of inducement, it is the batteries interior that mechanical collision, extruding causes respectively short circuit on fire, excessive charge discharge or wait for the on fire of short circuit of batteries inside and outside that cause into water, in-house component shakes the on fire that the resistance that cause increases or in-house overheat causes. Heat up the chain reaction of out of control, be just like a domino, can bring explosion 2 times even. For example once the lithium cell that tesla place uses produces hot out of control, the energy that batteries group releases is as high as 480000KJ, be equivalent to the energy that place of explosion of dynamite of 114 kilograms of TNT produces.
In the meantime, as a result of the character of batteries, when producing electric car spontaneous combustion use water undertakes put out a fire can cause batteries bedding face to accumulate short circuit, can produce explosive accident when put out a fire even, cause casualties 2 times. And powder and carbon dioxide put out a fire because not as good as the specific heat capacity of water, cannot undertake dropping in temperature effectively to batteries, bring about cannot extinguish igneous cause from fountainhead. Although had extinguished bright fire, batteries interior overheat cannot pass naked eye observation, still put in the danger of resume combustion or explosion.
The difficulty of electric car cut out an engine brings about a lot of moment to prepare inadequate fire fighting action to cannot redeem a loss effectively, make fire fighting personnel is put in extremely high risk even.
Although extinguished the electric car of spontaneous combustion, insurance compensate pays still is the problem that a your poll is fond of. Because danger of car spontaneous combustion is belonged to advocate a outside danger additional risk, the clause with more requirement and multiple accident appraisal bring about what a lot of users plant to this danger to cast defend initiative not tall. Although can obtain compensate to pay, compensate pays amount also with car age and car price link up with, add of on 20% avoid compensate absolutely, the loss is redeemed through insurance hard.
Since electric car spontaneous combustion exists such risk and hidden trouble, why cannot put an end to great majority to be not inevitable spontaneous combustion incident through technical reason? The governmental subsidy of this as electric as the last few years car is having very close connection.
The basis is pure dynamoelectric take policy of the allowance that use a car, 2017, in ＜ of E (Wh/kg)] of density of energy of 90 ≤ E[120 when, allowance coefficient is 1, the allowance coefficient 2018 is 0.6; 2017, e ＞ 120 when, allowance coefficient is 1.1, 2018, ＜ of 140 ≤ E 160, allowance coefficient just is 1.1.
But electric car and fuel car are having bigger distinction on mechanical orgnaization, phase of early days research and development needs to invest many capital, and electric car allowance has a day to will cancel eventually, a lot of capital are convenient seek way of capital of short-term steam again.
Brought about car look forward to to search those who seek cost to reduce through all sorts of means so, and supplier of a few batteries is the gain that keeps certain to do not have circumstance of sufficient test and verify to fall to undertake batch offers money in batteries. Such phenomenon inside the industry cans be found everywhere: To take subsidy, a few companies still mature not completely in the technology and below the circumstance that lacks strict test and verify, project of batteries of density of high energy of hurried mount a horse is produced, the electric car sale that will have hidden trouble finally gives fine long hair unwitting user.
Actually, the manufacturing mode of such eager for quick success and instant benefit is not can search without mark, can be found everywhere in the industry of science and technology that gives priority to with the mobile phone, the line on early days provides the product of competition ability more, later period upgrades through software the problem that solves an user to arise in use process. When the SamSung before this faces mishap of mobile phone explosion, also want to solve a problem through such means even, choose stop production recall finally by force of pressure.
To product of science and technology, a lot of users do not mind such product, because improving the participation in the process to feel,the user can be satisfied on certain level, but the premise of core is not to involve life property security. Although electric car comes up from essence,tell also belong to product of science and technology, but it bore the weight of the life of the user is safe, appeared when electric car problem, improve also redeem miserable final result hard.
We never repudiate the way that electric car is future, but perfect product just is truly cogent demand, conservative car falls into disuse gradually probably at the times, but the concept of research and development that innovation and reliable and collateral ability are car look forward to.
In the times of innovation, the user is willing to try, go trusting, but this is not car look forward to the reason of to gain fund sacrifice life. The user is not the small white rat of car look forward to.
