The power horse car before a week because spontaneous combustion, lift to retreat order tide, also make everybody safe to the electric motor-car of latter conflagration the problem is faint and anxious, and the motor-car of force sail report August 31 in the street on fire spontaneous combustion, cause consumer to be opposite again the doubt of the technology of electric now car and safe problem.

Appear on the market 2 many months with respect to on fire, be batteries back boiler?
A pensile green is new on August 31 the pure electric car of license plate of the sources of energy in the street on fire spontaneous combustion, spot billow smother, car bottom has deflagrated appearance. Because conflagration did not get be puttinged out in time, this pure electric car is ultimate by complete burn down.
As we have learned, on fire burns igneous electric motor-car, be Li Fan 650EV. The data shows, this model appears on the market up to now only 2 many months, the price before allowance is 16.89-17.58 10 thousand yuan, deduct subsidy price to be 7.99-8.68 10 thousand yuan, the government call course of development of integrated add boat 305km.
After seeing video, most netizen because the quality of this electric to Li Fan car expressed to be anxious.
How does the batteries package that the netizen expresses Li Fan in the comment rely on the lithium battery that the company offers by Suzhou.
And to on fire reason, li Fan is 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 immersing, the client detects not actively with service station connection, after this uses a car in the client when, because of electric core short circuit, cause batteries to catch fire.
Li Fan's means: Batteries bubble water and user do not have seasonable overhaul, do not have the relation of one wool money with Li Fan. But, according to Li Fan measure an outcome oneself computative, the Li Fan 650EV of on fire of this spontaneous combustion, be waterproof check or cause?
Look according to be versed in the product that believe a ministry declares catalog, li Fan 650EV used the cell of 3 yuan of lithium that offers by Tianjin force god, proper motion Pack is assembled, total energy is 43kwh, energy density achieves 144wh/kg. And at present main form is 3 yuan of batteries of force god 18650 or 21700 columnar type, at present besides Li Fan, be like,still be Jiang Huai, on such own brand offers steam, Chang'an, auspicious, east wind electric core.
Believe the friend of familiar and electric car knows, battery of 3 yuan of lithium this relative to phosphoric acid with respect to stability Tie Li is differred a few, need more expensive safe system to provide protection, especially the columnar batteries of 18650/21700 structure. Because compare mild package and aluminous carapace batteries for, compose the sentence of group of same size batteries, the columnar batteries amount of need wants many much, and defend to the safety of each report core appear crucial. The car look forward to such as the tesla that uses this cell at present, Jiang Huai all used every report core to design insurance alone, design occurrence breakdown of individual report core to be sure at any time the safe system of fusing. At the same time complementary with batteries of intelligent liquid cooling lukewarm control a system, make sure batteries group hour lies below proper working temperature.
It is a foundation with this, most enterprise can assure, traffic power cell achieves IP67 to defend level, and be after the bubble water of 30 minutes of less than, dynamical cell does not have breakdown. Go up among them the expression of steam particularly conspicuous, ceng Duo second dynamical cell direct as to immerse in water, be as long as 5 days of above, after be being taken out, use normally. The IEV5 series electric car of river the Huaihe River, the accident that ever also had produced bubble water more than 2 hours (because of the flood) , after the event is car cannot be started normally only, do not have phenomena of any on fire combustion.
And although the dynamical cell of Li Fan 650EV is long-range monitoring does very reach the designated position, but its still use inchoate wind cold pattern to come loose hot system, can not assure the regular job temperature of batteries at any time. In the meantime, the batteries team that proper motion Pack assembles is in safety performance respect, see apparent leave a matter for future consideration natively from the hair of accident of on fire of a few spontaneous combustion. The security that its provide defends system, apparent unwarrantable short-circuit in batteries 100 percent after the problem, sever the link of electric core, cannot avoid the high temperature that causes because of short circuit, to cause spontaneous combustion accident.
So, li Fan cannot swing boiler completely to give batteries, want to investigate a matter from oneself, of the quality that this also revealed motor-car of force sail report with the problem of safe hidden trouble that exists really.

How many safeguard do the technology of car of new energy resources that relied on gain of new energy resources to take subsidy and safety have after all?
Actually, li Fan is dynamoelectric the accident of spontaneous combustion on fire of the car, not come singly but in pairs. Be in early in June 2016, li Fan 320EV produced accident of on fire spontaneous combustion one case, the time that is apart from this model to appear on the market formally also by a definite date is not far. This spontaneous combustion, everybody expresses to be anxious badly to product quality of Li Fan.
The newspaper in be being announced late on August 17 according to force sail share shows, be in advocate business Wu respect, force sail share is new first half of the year board of the sources of energy piece data is first-rate. 2018 first half of the year, the quantity of produce and sale of car of new energy resources of force sail share mixes 3195 for 3495 respectively, relatively the corresponding period grew respectively last year 82.41% with 96.74% . Li Fan's major nowadays gain is relying on business of new energy resources.
But in fact, product of new energy resources makes consumer afraid indeed, the Li Fan before this still is immersed in " cheat fill " disturbance. 2016, force sail share releases announcement to affirm, sail of subsidiary Chongqing force receives the processing that the Ministry of finance allots to decide by the limited company that use a car, do not accord with allowance of car of new energy resources to declare conditional car to add up to 2395, involve fund of central finance allowance to amount to 114 million yuan, to cars of afore-mentioned new energy resources central finance does not grant accessorial, cancel Li Fan to multiply with the car finance accessorial capital dials a qualification beforehand in the center of 2016.
And the Li Fan 650EV that catchs fire this is in appear on the market before long hind, total bureau of supervisory government of market of Home Ceng Zaiguo is forced below state of affairs of investigation of the defect that start recall passes, the reason is special sheet fast the occurrence problem such as program of controller of transmission, electric machinery. Recall 307 330EV1 are pure electric car; 4719 330EV2 are pure electric car; 1405 650EV1 are pure electric car, in all 6431. The car measure that the car of this recall catchs up with half an year is produced is similar, make everybody new to Li Fan more the quality of car of the sources of energy generated suspicion.
Latter, as the allowance of the encouragement of policy and government, car of new energy resources seeks swift and violent progress, from the point of data, before this year 7 months, produce and sale of car of our country new energy resources finishs 504 thousand to mix 496 thousand respectively, than going up year of the corresponding period grow respectively 85% with 97.1% , quantity of produce and sale anticipates inside Yuan Chao course of study. Will look by current condition, the future of city of car of new energy resources a light. But this does not mean all car look forward to to be able to stand firm in this fractionize market.
Summary: On fire of sail of power horse spontaneous combustion, force, accident of electric car spontaneous combustion happens again and again, everybody expresses concern to market of current car of new energy resources, whether does dynamoelectric trick-cycling art mature really? Whether was the market of new energy resources that the government gives aid to perfected really? No matter how, small making up those who want to say is the car look forward to that only sureness builds a car, final ability gains the market, win customer.
