Block be connected with monitoring modular and receive described information and be analyzed and external communication bus and process
Under state trigger control module be connected with control module and internal memory contain can fire-retardant and fire extinguishing gas molten
Glue is also controlled the aerosol memory module opened by control module when triggering, and described process state is determined
Justice is: when the analysis result that is analyzed described information is defective or directly receive communication bus and send
Triggering command and perform.
Further, the variations in temperature in every index of correlation includes casing in lithium ion battery casing, casing
Internal organic volatile substrate concentration and carbonomonoxide concentration, air refraction.
Further, in lithium ion battery thermal runaway pretreatment unit is installed on lithium ion battery casing.
Further, described information and analysis result are forwarded to communication bus by control module.
Further, communication bus is CAN or 485 buses, and communication bus is positioned at lithium ion battery
The outside of casing.
Present invention also offers a kind of process side utilizing above-mentioned lithium ion battery thermal runaway pretreatment unit
Method: in monitoring module monitors lithium ion battery casing every index of correlation and will monitoring gained information send to control
Molding block, is analyzed information after control module reception information, when control module analyzes dividing of described information
When analysis result is defective, or when control module directly receives the triggering command that communication bus sends,
Then control module triggers and controls to open aerosol memory module, and the aerosol in aerosol memory module is released
Put and realize fire-retardant or fire extinguishing.
Further, described information and analysis result are forwarded to communication bus by control module.
By such scheme, the present invention at least has the advantage that formation various dimensions effectively lose in heat
Pretreatment is carried out before control, fire-retardant, extinguishing effect notable, can really realize stoping or the generation of time delay thermal runaway；
Device own wt and volume are the least, easily install, can on the premise of not sacrificing vehicle-mounted product lightweight,
It is arranged on inside Battery case by the mode of easy industrialization, as screw is fixed, onboard power can be widely used in
In battery system and energy storage battery system.
Described above is only the general introduction of technical solution of the present invention, in order to better understand the technology of the present invention
Means, and can being practiced according to the content of description, below with presently preferred embodiments of the present invention and coordinate attached
After figure describes in detail such as.
Accompanying drawing explanation
Fig. 1 is the structural representation of lithium ion battery thermal runaway pretreatment unit of the present invention.
Detailed description of the invention
Below in conjunction with the accompanying drawings and embodiment, the detailed description of the invention of the present invention is described in further detail.With
Lower embodiment is used for illustrating the present invention, but is not limited to the scope of the present invention.
Embodiment: a kind of lithium ion battery thermal runaway pretreatment unit, it include power module, monitoring modular,
It is connected with monitoring modular and gas that the control module of external communication bus is connected with described control module
Colloidal sol memory module.
Power module is for being powered whole device.
Monitoring modular be used for monitoring lithium ion battery casing in every index of correlation and will monitoring gained information send
To control module.In variations in temperature in every index of correlation includes casing in lithium ion battery casing, casing
The organic volatile substrate concentration in portion and carbonomonoxide concentration, air refraction etc..
Control module is for receiving the monitoring information that monitoring modular is sent, and is analyzed judging to it, when
When analysis result is defective, then triggers and control to open aerosol memory module；When control module directly receives
During the triggering command sent to communication bus, also can trigger and control to open aerosol memory module；Control
Module can also be by the monitoring information received and information is analyzed self the analysis result of gained forwards
To communication bus, so that this information and analysis result carry out display alarm for onboard system screen to driver
And the analysis of other performance state of vehicle judges.
Store aerosol in aerosol memory module, this aerosol can starvation, cladding electrolyte and
