2018, pure electric car has a place " fire " . If the condition is permitted, a lot of people dream to have motor-car of a pure report. Produced accident of spontaneous combustion of two pure electric cars continuously recently nevertheless, labour believes a ministry to call-over to point to the safety that should pay close attention to pure electric car continuously. Want to buy the person doubt of pure electric car more very much: Show level what rate does the batteries security of pure electric car achieve? Can you lean after all?
Case answers put: Spontaneous combustion of batteries of pure electric car happens time and again
On August 31, a Li Fan is pure spontaneous combustion of electric car on fire, because conflagration did not get be puttinged out in time, this car is ultimate by complete burn down. According to manufacturer after on-the-spot reconnaissance preliminary decide the reason that car batteries catchs fire is: Guangzhou day after day rainstorm, this car is immersed to exceed 2 hours by rainwater, bring about batteries small leakage, after this uses a car in the client when, because of electric core short circuit, cause batteries to catch fire. Additional it is reported, the motor-car of pure report of Li Fan 650EV of on fire appears on the market only two months. And be in several days ago, still produced an accident of conspicuous electric car spontaneous combustion, build car business newly an EX5 of power horse car is in Chengdu academy produces spontaneous combustion inside garden area, power horse government says: The researcher is violated compasses connect conductance to send short circuit forcibly, cause batteries to wrap spontaneous combustion.
Entire media reporter is advertent, the price after allowance of two pure electric cars does not consider above expensive, belong to 8~15 10 thousand yuan of level, nevertheless price discretion and accident of electric car spontaneous combustion do not have connection, this year in January, model S of a tesla is in Chongqing to did not charge, below the circumstance that was not collided, batteries system catchs fire cause spontaneous combustion. Pure dynamoelectric and public transportation also have accident of similar spontaneous combustion. On August 26, a pure dynamoelectric bus of cupreous hill city that installs triumphant passenger car to make because batteries breakdown on fire. According to not complete count, 2018 first half of the year, produce car of accident of electric car on fire domestic and internationally to involve the brand such as tesla, bronco, Jiang Ling, numerous peaceful in all.
Labour believes a ministry: Safe problem has become the cold water of the first gourd ladle of the industry
Incident of on fire of pure electric car, invite safe problem by focusing. Chinese automobile industry grew on September 1 (peaceful is amounted to) on international forum, national industry and Qu Guochun of vice director of department of industry of informatization ministry equipment make a speech and emphasize, security is development of car of Chinese new energy resources must retentive bottom line, safety builds a car, build safe car, it is the justice that look forward to of car of new energy resources should retain in this times. He says: "Incident of successive recently spontaneous combustion of car of new energy resources is already enough ring alarm bell for whole industry, swarm into new energy resources as many car look forward to, safe problem has become the cold water of the first gourd ladle of the industry, we need to go to this thinking calmly necessarily. We need to go to this thinking calmly necessarily..
Be versed in the data that believe a ministry shows, car of Chinese new energy resources is already successive 3 years produce and sale measures the whole world the first, accumulative total popularizes gross of car of new energy resources to exceed 1.8 million. But the car of new energy resources that current our country takes gross of produce and sale to have 3% only, however company of many 200 car is in " make " .
The personage inside course of study points out to the reporter, car of our country new energy resources disperses quite from the point of the industry, product technology level is uneven, although car of our country new energy resources produces sales volume to had been in the world to precede, but car of new energy resources is in company of many 200 car dispersedly, the good and bad are intermingled of hard to avoid of production level irregular.
The reporter arrives alertly, ministry of national industry letter just announced a country this year in January " electric car uses safety of accumulator of lithium ion motivation to ask (ask for an opinion to stalk of grain) " . And the aspect checks in safe collision, c-NCAP just just also increased to be aimed at the requirement of the collision project of pure electric car.
Investigation: Does electric car batteries can't bear biff really?
From the point of all sorts of spontaneous combustion reasons, the batteries of electric car is not to get rainwater test already, be unable to bear high temperature again, still do not endure collision? In fact, code is right related the country but the security of batteries made strict provision.
The reporter consults data discovery, according to the country qualitative check total bureau releases " electric car asks to reach experiment method with dynamical accumulator safety " in, point out the safe index of conformity of batteries clearly, means of among them test and verify also is head and shoulders above the condition that we come up against daily.
In boreal steam new energy resources changes communication of the power station to be able to go up, the technologist that comes from peaceful heart times tells a reporter, after leaving factory, the batteries of electric car is closing completely, and car manufacturer also can do safe test. With examining the waterproof properties of batteries group is exemple, can immerse batteries group 24 hours are in in water, undertake detecting to the each function index of batteries again, in order to avoid external water enters batteries interior to cause short circuit.
"The safety of dynamical cell, it is high pressure and chemical and safe coupling, bigger safe hidden trouble is formed after this brings about high-pressured dependability and chemical and safe union, the many levels such as chemical safety, high pressure safety, rigid security, function security and applied safety included among. " Huang Shilin of Ning Deshi's acting president admits, the security of dynamical cell is very complex. Inside current job, the manufacturer that includes peaceful heart times to wait is on safety of dynamical cell product go after 0 accidents, besides the safe monitoring on production and character, still collect service data in real time through long-range supervisory system, will reduce an accident. Nevertheless, the reporter arrives alertly, force sail car expresses after spontaneous combustion accident happens, the hidden danger of existence of electric car batteries that ever discovered this user in long-range monitoring, but " do not have there's still time to inform " with respect to spontaneous combustion.
Unscramble: Short circuit of summertime high temperature, batteries is spontaneous combustion advocate because of
Pure electric car serves as a newly emerging things, motivation comes from batteries, batteries collides in high speed the security after, if whether can catch fire, explosion, bring about personnel to get an electric shock, release harmful gas, whether does the structure install bodywork congruent and a lot of problem, it is the major issue that affects safety of property of every consumer life, so after all the security of car of new energy resources that current pure electric car gives priority to how? Why to meet spontaneous combustion?
Basis of entire media reporter publishs a material discovery of not complete count, it is 13 cases about up to the accident of electric car on fire that is exploded to go out by August this year, 56 months when come in the summer among them " gather together " produced accident of electric car on fire 5 cases, make tall hair month, the specification is first half of the year 56 months the tall hair month of accident of electric car on fire. The force sail car that makes findings report to spontaneous combustion expresses, the weather such as summertime high temperature, rainstorm can affect the safety of electric car. In addition, take the field that using a car is tall hair of accident of electric car on fire, in the accident of pure dynamoelectric spontaneous combustion that publishs external in 12, occupied 11 cases, having in addition is a bus together, shed accident of car happening on fire for content together. Look from the reason, because fill the on fire accident that conductance causes in all 5, become the first inducement of on fire accident; It is collision on fire, static next the spontaneous combustion of short circuit of the batteries in putting, spontaneous combustion in travel. As a whole, reason of oneself of summertime climate, batteries, cause spontaneous combustion of pure electric car easily.
Clew: Inferior charge equipment easy generation is filled too, owe fill wait for a problem
In view of this year accident of spontaneous combustion of many electric car is happen when charge, come from Biyadi the expert Liu master of factory of this locality maintenance expresses, of electric car charging also is very important one link, the charger that chooses safety is very important also.
Liu master hints, when use, the batteries capacity AH that the user wants to decide batteries of very electric car the output electric current of former perhaps charger, notice the voltage model that mentions expressly in batteries box, good charger should decide when charging negative pole, if do not take care to do,turned over, with respect to meeting attaint charger and storage battery. He points out, must choose brand name big, public praise charges well picket or charger product, on the market charge inferiorly not less equipment has arisen very easily to fill, owe fill, dehydrate, the phenomenon such as vulcanization, it is very big hidden trouble to the person of consumer and belongings safety. The proposal must search to provide the place that electric car charges technically, do not want oneself to buy an electrical outlet to charge at will, otherwise safety does not have safeguard.
