[Channel of new energy resources of car love card is achieved formerly]
Driving build car new power whip and spur the nice and warm of batch consign is strong, be about to begin the power horse car of consign at next month, produced accident of car spontaneous combustion one case on August 25 however. Accident at that time, experience thing car park is inside academy of Chengdu of power horse car.
On August 29, open letter of republication of government of power horse car, car of farther clear spontaneous combustion is the trial assembly car with power inchoate horse. Open letter shows, on fire reason is, in do not allow to already discarded as useless below the case that car has electrify is started, an employee deregulation, forcibly electrify, spark risk of car short circuit, bring about batteries bag to produce spontaneous combustion.
Current, disturbance already subsidise, but about electric car, especially the safe problem of dynamical cell, cause wide attention once more.
Saw the following point, the article calculates read an in part
Common occurance of accident of on fire of car of new energy resources, batteries safety is caused again take seriously;
Batteries of columnar, quadrate, mild package who is safer?
Accident of on fire of car of new energy resources ends up with nothing definite, accident analysis, solve the industry such as measure to supervise a mechanism to be built urgently.
Common occurance of accident of on fire of car of new energy resources
Although incident of spontaneous combustion of car of power horse trial assembly belongs to precedent in building car new power, but will look from market of car of whole new energy resources, already common occurance.
Public data shows, according to not complete count, this year 1-6 month, produce accident of electric car on fire domestic and internationally to had been achieved 10 cases in all, relatively the corresponding period increased 1 case last year. Among them, home happens 8 cases, involve a brand to include new energy resources of bell of bronco of tesla, Sichuan, river, numerous peaceful to wait; The United States happens 2 cases, all be tesla model.
Forth date from, from 2013-2016 year, as our country car of new energy resources retains the rapid growth of the quantity, accident of on fire of car of new energy resources also year after year is climbed litre. Mixed 2013 2014, accident of on fire of car of domestic new energy resources is mixed 4 cases for 2 respectively, and added directly 2015 come 14 cases, 2016 is to be amounted to 29 cases more.
From the point of experience thing car, include new energy resources to multiply not only with the car, the on fire accident of passenger car of new energy resources also holds very large proportion. For example, in the accident of 29 on fire 2016, only passenger car of new energy resources is amounted to 18 cases, still have on fire of a special vehicle, and it is 10 cases by accident of the on fire that use a car.
Although amount of accident of on fire of car of new energy resources, compare at present at its the market retains for the quantity negligible, but the safe problem about car of new energy resources, it is an obligatory course that remains to be perfected further likewise.
From the point of on fire reason, having many car is when charging, or spontaneous combustion happened in travel process. This among them, the security of dynamical cell becomes the question with the biggest dispute inside course of study. Differ especially model, tie-in and different power cell, its product quality is uneven also.
Batteries of columnar, quadrate, mild package who is safer?
Appearance of driven power cell perhaps is enclosed look on means, cent of batteries of ion of the lithium on current market is cylindrical, square and mild package batteries 3 kinds. About the discussion of security of cell of these 3 kinds of power, also be the key that the industry argues all the time. In fact, carry the model of these 3 batteries, more or less had had the other perhaps trouble of car on fire.
For example, cylindrical the delegate tesla MODEL S of batteries, only in October 2013, in November two months, produced on fire accident 4 cases in the United States. And nearly two years, be exposed to the sun to go out constantly as before about the on fire accident of tesla. This year 1-4 month, the accident of global on fire of MODEL S and MODEL X already had 5 cases, 3 happen in the United States, 2 happen in domestic Chongqing and Shanghai respectively.
And Jiang Huai IEV5, IEV6E, numerous Tai Yun 100, what E200 also embarks is cylindrical batteries. Last year on June 26, IEV5 of a Jiang Huai is in Beijing spontaneous combustion of 3 lis of collect happening; Of the same age on December 31, IEV5 of a Jiang Huai is in Beijing Xizhimen spontaneous combustion happens inside some village. And 3 years nearly two, car of numerous peaceful new energy resources also has produced spontaneous combustion accident at least 3 cases.
Compare batteries of Yu Yuanzhu form, day department and heart department car more apt uses quadrate cell, for example acute of abundant cropland general this, I3 of E-Golf of dynamoelectric edition of Focus of Ou Lade of 3 water chestnut, Ford, masses, BMW, I8. The spontaneous combustion message that concerns these car is opposite less, when 2016, BMW I3 is exposed to the sun to produce spontaneous combustion in Italy.
But this can not explain quadrate batteries is safer, the car that home introduces quadrate batteries also from time to tome spontaneous combustion message exposes to the sun piece. For example, boreal steam new energy resources, Biyadi, strange luck, auspicious wait for brand model to all had produced spontaneous combustion accident.
See mild package batteries again, use model has general snow Folanwo is La Da, contemporary case inferior mix move Suonada, K5 and K7, day to produce listen wind, Ford Fox is dynamoelectric FF91 of edition, Faraday, concern the message at these model spontaneous combustion rarely nevertheless. And home also has a few models to carry mild package battery.
From the point of the accident amount of the model, it seems that photograph of mild package batteries is more columnar than be being mixed at square for batteries, security is higher. But, this is miniature relative result merely, and, this still depends on the scale that accident car takes model total sales volume. For example, carry the car of square and columnar batteries mostly, the photograph is taller than sales volume of car of mild package batteries, because ratio of this matter reason is relative also bigger. But because do not have accident of specific electric car spontaneous combustion at present,analysis and all computation are occupied, accordingly, this one conclusion still has need checking card.
Accident analysis, solve the supervisory mechanism such as measure to be built urgently
Although accident of on fire of car of new energy resources exposes to the sun again and again,go out already common occurance, but often after a heat is discussed, seek a copy to the get to the bottom of sth of on fire reason, and solve measure, and discard as useless finally car whereaboutldirection end up with nothing definite. Well-known, an electric car carries the dynamical cell of tonnage class, once on fire perhaps damages, handle undeserved meeting to bring serious pollution to the soil of trouble spot, environment.
Retain as car of new energy resources the rapid growth of the quantity, the accident rate of car of new energy resources also is sure to present growth state. When if be in,system capacity has not reached a large number of level, the trouble removal that did not perfect and supervisory mechanism, answer the lash-up of prospective more accident probably to handle hard.
Accordingly, wait in the light of measure of the accident analysis such as on fire of car of current new energy resources, early-warning and processing, the mechanism of supervisory government technological process that publishs system of one a complete set of is very crucial and extremely urgent.
Once had corresponding processor to make, not only can analyse accident reason through data, optimize 3 cable technology further, charge the technology, still can mix accident reason at the same time should undertake classified to measure, answer future better then more sudden accidents. Not only such, this returns the insurance of car of will new to future energy resources, after service to wait, provide the basis that more can perfect. Of course, also can have very main effect to environmental protection.
Editor summary: If not be power horse car is one of delegates that build car new power, oneself is had enough much discharge, be afraid the report to spontaneous combustion of car of new energy resources also so won't deep. When a kind of phenomenon is common, also have little the value of more attention. But this is told to industry of automobile of new energy resources, it is a kind of thinking that cannot take extremely. Face numerous the spontaneous combustion car that end up with nothing definite, ought not to establish corresponding early-warning and processing mechanism earlier? It is in accurate data only rely on under, ability divides separate out truly, after all which kinds of batteries is safer.
