In recent years, below the support of new policy, impetus of development of car of new energy resources is swift and violent, car of new energy resources of increasing consumer favour. According to statistic, be in early output of car of our country new energy resources had surmounted the United States to achieve 379 thousand 2015, make market of car of the greatest new energy resources. And arrived this year, before the volume of produce and sale of the car of new energy resources August goes high continuously as before. Data shows, 1-8 month, produce and sale of car of new energy resources mixes 601 thousand for 607 thousand respectively, grow respectively compared to the same period 75.4% with 88% . However, high-speed grows backside, amount of incident of on fire of car of new energy resources also relatively in former years shows fast ascendant trend, enter especially mixed in August since September, incident of open on fire has been amounted to 12 cases, outclass of this one word 2016, 2017 all the year round amount of open on fire.
Which part is electric car easy a kind of firecrackerfire breaking out?
The accident about on fire of car of new energy resources already common occurance, mention electric car on fire, current the biggest spearhead can point to dynamical cell continuously. Lithium battery because chemistry is lively, acquired the character with high density of bulk small size, because this made the dynamical battery with the most wide application in pure electric car. But also active because of its property, the lithium metal in lithium battery is extremely easy as severe as the aerobic free captive animals in air oxidation reaction, release much heat, produce severe inflammation thereby. Apply currently the most extensive is battery of lithium of phosphoric acid iron or battery of 3 yuan of lithium, they have natural risk however, tinderbox all is electrolyte, batteries of 3 yuan of material is easier among this ignite electrolyte. And not only such, the influencing factor such as control of process of technology of material, diaphragmatic, binder, structure, heal, production, production, can build accident of car on fire happen.
Are the sort of dynamical cell and safety relevant?
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.
On fire is with one's eyes open
Look from new this year energy resources by the subsidy level that uses a car, add boat course of development moves car allowance amount to be reduced somewhat in the pure report under 300km, but the allowance of pure electric car of boat of 300km above add not only did not fall, grow somewhat instead. In addition, newest allowance policy sets, pure dynamoelectric the energy thickness that takes system of cell of the power that use a car not under 105Wh/kg, emphasize, the allowance amount of bicycle and density of batteries system energy are direct link up with.
That is to say, new allowance standard more encourage add boat course of development density of long, energy the model with low power consumption of tall, 100 kilometers. Since had higher interest, with respect to somebody thering is no lack of because of money turn sb's head. Look forward to of a lot of cars begins blind to raise density of dynamical cell energy to cater to allowance, and to the security of batteries they choose turn a blind eye to. In fact of density of lithium battery energy raise need anode and negative pole material to have the bigger improvement, tall voltage that matchs to it electrolyte, high temperature resistant security of craft of diaphragmatic, Bu Li, batteries controls high strenth the technical research such as structure of protection of structure, system, need near 24-28 lunar time. So do those add boat mileage that increase for an instant pass this really " 24-28 month " did the technology study? Say but really artful, change in allowance policy when, they study.
Write finally
Tell the truth, as consumer we look be like active, but be passivity. The safety that knows perfectly well electric car does not amount to mark on certain level, have however must buy. Be here or install benefit to use the note of electric car to everybody.
1, the attention charges method. The proposal is used shallow fill shallow put way, want to make sure car n is enough. No matter distance is far close, make after giving out, want to charge instantly, along with put along with fill, do not be over to n total depletion just charges.
2, do not use for long, suggest half report is deposited. Long unused need not when, general proposal batteries carries the electricity of 50% , do not suggest to be full of, such is helpful for that prolong battery service life, maintain the active of batteries.
3, regular examination maintains. If the add of electric car drops considerably suddenly during travel course is short, appear very likely the breakdown such as short circuit. Answer to have examination, repair in time to professional door inn, accomplish be on guard Yu Weiran.
4, car of not optional park. Summertime high temperature is rainy, the car to car besides the effect is apparent, because of this park to electric car, also need to notice to fall, park place suggests to choose shady and cool, ventilated place, have the place with hide, higher relief, can avoid car to insolate so, rainstorm drenchs by force and water adj/LIT wide.
5, finally, the power that the car holds charger wants ambitious at common electric home appliances
