The position of the single battery 200 of raw quick-fried spray generates fire extinguishing information and the fire extinguishing information is sent to extinguishing device.
S200, the extinguishing device receive the fire extinguishing information, discharge extinguishing material to the monomer that quick-fried spray occurs
Battery 200 is sprayed.
Specifically, when the ultrasonic detector 120 detects ultrasonic signal, conversion elements convert ultrasonic signal
For electric signal, by the electric signal transmission to external management system, the management system obtains ultrasonic wave according to electric signal
Intensity, therefore, it is determined that the single battery 200 of quick-fried spray and the distance value of the ultrasonic wave occurs, according to multiple ultrasonic waves
The distance value that detector 120 obtains, judges the position for the single battery 200 that quick-fried spray occurs.
The extinguishing material and the substance generated after chemically reacting can be attached to 200 surface of single battery, institute
Stating single battery 200 cannot recycle, and the embodiment of the present invention is reducing temperature, extinguishing or prevent cells burst as far as possible
In the case that purpose is realized, sprinkling extinguishing material as small-scale as possible allows other not by attaching extinguishing material and changes
Learning the single battery 200 of substance generated after reaction can be utilized again, more environmentally-friendly, economize on resources.
In the present embodiment, the extinguishing device includes controller and multiple fire extinguishing sprayers 131, referring to Fig. 6, based on above-mentioned
Consider, S200 described in the embodiment of the present invention further includes S201 and S202.
S201, the controller receive the fire extinguishing information that the management system is sent, and the fire extinguishing information includes that correspondence is opened
131 information of fire extinguishing sprayer opened.
S202, the controller open corresponding fire extinguishing sprayer 131, discharge the extinguishing material according to the fire extinguishing information
To spray the single battery 200 that quick-fried spray occurs, the corresponding fire extinguishing sprayer 131 is that the described of quick-fried spray occurs for distance
The nearest fire extinguishing sprayer 131 of single battery 200.
The embodiment of the present invention also provide a kind of quick-fried spray detection system of battery, including battery modules, batteries management system with
And the above-mentioned quick-fried spray detection device 100 of battery, the ultrasonic detector 120 and fire extinguishing dress of the quick-fried spray detection device 100 of battery
