Controlled partly at 3 o'clock on May 4 afternoon
Hangzhou carries one parking lot south 9 fort big bridge inside
On fire of 8 electric cars
This is not incident of on fire of motor-car of the first report of Chinese

Controlled at 8 o'clock in the evening on April 21
A tesla of Shanghai is abrupt spontaneous combustion on fire
On April 22 afternoon
An ES8 in be being maintained comes in Xi'an colourful accredit service center produces combustion
On April 24
Wuhan produces Biyadi one case incident of E5 on fire
The government responds to batteries to wrap good nondestructive
It is reported, the tesla model of Shanghai happening spontaneous combustion is Model S P85
At present already stop production
According to not complete count, up to now, inside global limits
The electric car of tesla reachs explosive accident in travel, collision and the combustion that fill conductance to send, spontaneous combustion
Had happened more than 50 cases
Be called even the champion of " fork truck "
The accident of electric car on fire that produces again and again
the safe problem of electric car and dynamical cell
Push again to the where the wind and the waves are highest of public opinion
For fast developing market of car of new energy resources cheated a shadow
Why the batteries of electric power car time and again " ham " ?Short circuit of pool of batteries collision, static discharge is advocate because of
In accident of electric car on fire
It is for the most part rise because of batteries
Include spontaneous combustion of traffic accident collision, short circuit to wait a reason a moment
The promotes technology of traceable lithium battery rapid development of electric car
Before applying extensively at electric car
Mobile phone and the accident that jotter batteries combustion explodes already common occurance
On electric car
Each individual batteries core comprises batteries
A certain quantity of batteries is arrived to form module of batteries model group together by combination
The space that carries battery as a result of car jacket is limited
The number of batteries model set that moving place wants is larger also
Batteries can discharge with different times
Produce a large number of quantity of heat with different rate
Accumulate plus time reach dimensional influence
Bring about batteries group to run environmental temperature condition thereby complex and changeful
To the circumstance of specific batteries on fire
Song Jian of vice director of safety of standing assistant dean, automobile and energy-saving state key laboratory introduces academy of development of project of Tsinghua university car
Because batteries interior electrolyte reachs his to decompose child to be ignited to cause,this is commonly
Song Jian points out, be configured with combustible dissolvent and the electrolyte in lithium battery is become, of lithium battery fill discharge process, it is the athletic process of ion of the lithium in electrolyte. Lithium is a kind of lively metal, if the lithium inside batteries is exposed in air, with respect to meeting and aerobic generation intense reaction burns then.
Enter batteries interior to prevent air
Car batteries manufacturer can be used commonly multilayer crust or model film will close batteries
Make lithium won't be contacted with oxygen
The manufacturer also can encrust in batteries wrap up is hard protective carapace
Nevertheless, in the environment that batteries interior is " flimsy " another
At present electric car manufacturer is density of pursuit high energy, Gao Xuhang
The diaphragmatic ply in meeting general batteries undertakes cutting down
Caused certain safe hidden trouble to batteries
Song Jian introduces: "The research result of our lab, imitate electric car to produce the condition of acuteness collision, batteries falls in certain collision wallop and air intensity of pressure, film can produce burst, the oxidant on positive electrode produces chemical reaction easily with electrolyte, of batteries negative pole short-circuited, local temperature is elevatory, likely the electrolyte of ignition batteries. Likely the electrolyte of ignition batteries..
The batteries on electric car is to pass series-parallel connection to become group of jobs
Single cell group (or batteries is wrapped) after producing hot out of control
Local the energy that release to all round transmission
Cause the likelihood all round the hot out of control of batteries
Chain reaction is caused between core of thousands of batteries
Call pool group to have hot flee in terrorfry in deep fat or oil in the round eventually
Release tremendous energy
Fall in extreme circumstance so
A little trouble can cause disastrous consequence likely
