The battery pack 10 should be a kind of prior art in itself comprising the battery pack 11 of multiple groups serial or parallel connection, with
An and sealing shell 12 being coated on the outside of the battery pack 11.It is envisioned that each group of battery pack 11 all includes more
Piece cell piece, these cell pieces can be set according to actual needs with serial or parallel connection together.The cell piece is
Details are not described herein for the prior art.The sealing shell 12 is usually made of insulating material, can be with fire proofing, such as TVP (heat
Plasticity vulcanized rubber) material is made.
The temperature smoke detectors 20 include at least one temperature sensor 21 and at least one smoke detectors 22.Institute
It states temperature sensor 21 and refers to the sensor that can be experienced temperature and be converted into usable output signal, may include multiple, and be distributed
Different location in the inside of sealing shell 12, to obtain the temperature value of the battery pack 10 everywhere immediately.The temperature sensing
Device 21 as a kind of prior art, details are not described herein.The smoke detectors 22 refer to for detecting in certain area model
It whether there is specific gas in enclosing and/or can continuously measure the sensor of gas composition concentration.The smoke detectors 22 can be with
For calorifics formula gas sensor, electrochemical gas sensor, magnetically gas sensor, optical type gas sensor, partly lead
Body formula gas sensor, gas-chromatography formula gas sensor etc., are all used to detect the generated flue gas in sealing shell 12
Concentration simultaneously exports.The smoke detectors 22 can also be arranged in the different location of the inside of the sealing shell 12, with timely
Obtain the flue gas concentration value of 10 different location of battery pack.
The fire extinguishing cooling pump 30 can be a liquid-solid two-phase force (forcing) pump, can not only convey liquid cooling fire extinguishing material
Material can also convey solid cooling fire extinguishing material.The structure and working principle of the fire extinguishing cooling pump 30 itself should be existing
Technology is no longer described in detail herein.The fire extinguishing cooling pump 30 is used to open or close under the control of the control device 60,
So that fire extinguishing cooling material is conveyed into battery pack 10 by the fire extinguishing cooling pump 30 as needed.The fire extinguishing cooling pump 30 is also
Including at least one switch valve 31.The switch valve 31 can be a solenoid valve, can be according to the control of control device 60
Signal controls its switch.The quantity of the switch valve 31 can be set according to actual needs, because fire extinguishing cooling material has

The temperature value and flue gas concentration value that degree smoke detectors 20 are exported pump 30 to start or close the fire extinguishing cooling, that is, work as temperature
When the temperature value and flue gas concentration value that smoke detectors 20 are exported are more than some value, that is, start the fire extinguishing cooling pump 30.
And when being lower than some value, then close the fire extinguishing cooling pump 30.The temperature value that is exported when temperature smoke detectors 20 and
When flue gas concentration value is more than some value, the processor will directly initiate fire extinguishing cooling pump 30 will put out a fire or the material that cools down
Material is conveyed into the battery pack 10, i.e., the described processor can be automatically activated the fire extinguishing cooling pump 30.In addition, the control
Device 60 processed can also include a manual switch.The manual switch for starting the fire extinguishing cooling pump 30 at any time
Will put out a fire or cooling material is conveyed into the battery pack 12.Because in actual automobile use process, it is possible to battery
The spontaneous combustion that packet 10 occurs, but flue gas concentration value or temperature defined by processor starting fire extinguishing cooling pump 30 has not been reached yet
Value, such as in motor vehicle repair process.
The warning device 70 is electrically connected with the temperature smoke detectors 20, when temperature smoke detectors 20 are exported
Temperature value or flue gas concentration value reach a certain value, the warning device 70 i.e. start to alarm, as indicator light is bright or issue " serge "
Prompt tone.The warning device 70 the temperature smoke detectors 20 export when alarming temperature value or flue gas concentration value are less than
Or the temperature value or cigarette that the temperature smoke detectors 20 export when the fire extinguishing cooling pumps 30 are opened equal to the control device
Gas concentration value.
Compared with prior art, pass through provided by the present invention for the quick extinguishing cooling system of battery pack in battery pack 10
Sealing shell 12 in be arranged temperature smoke detectors 20, for detect the current temperature of battery pack 10 or inside flue gas concentration
Value, when the flue gas concentration value when the inside of the temperature or sealing shell 12 reaches a certain numerical value, 50 horse back of control device is opened
The fire extinguishing cooling pump 30 is moved to be cooled down or put out a fire so that fire extinguishing cooling material is conveyed into time in the sealing shell 12,
Life and property loss is avoided so as to flee from the vehicle to driver and conductor's time enough.
The foregoing is merely a prefered embodiment of the invention, is not used to limitation protection scope of the present invention, any in the present invention
Modification, equivalent replacement or improvement in spirit etc., all cover in scope of the presently claimed invention.
