Description
Technical field
This utility model relates to lithium battery structure, specifically a kind of battery system explosion-proof flame-retardant structure.
Background technology
The safety precaution of current lithium battery system is substantially voltage, electric current, temperature anomaly detection, it has been found that problem can only cut off charging and discharging circuit and warning, can only take fire suppression measures after battery catches fire outside battery system.The method not carrying out effectively fire extinguishing at internal battery pack.
Experiment and the explosion accident on fire of a large amount of lithium batteries, be that lithium battery core inner causes both positive and negative polarity internal short-circuit because of overheated or manufacturing defect mostly, causes battery core internal moment to produce a large amount of gases, and High Temperature High Pressure breaks through air blast on fire of meeting and get along well after battery core is packed.Almost all of lithium battery system is all made up of multiple lithium battery modules and more cell (or claiming battery core), and battery system on fire be all first by indivedual battery cores on fire after heat other battery core and then constantly cause the internal both positive and negative polarity short circuit of other battery core to form chain reaction passing through to roast, and burn whole battery system.Process on fire is first defective by the barrier film having individually the internal positive and negative interpolar of battery core or temperature distortion, cause positive/negative plate short circuit, battery core electric energy abrupt release broken ring barrier film further increases short circuit area, form quick vicious cycle, the materials such as the high heat meeting fast decoupled electrolyte produced, after high temperature hot gas breaks through shell, meet with air and blast on fire occurs.After battery system is internal on fire, carry out outer foam and liquid fire extinguishing, it is heated short circuit owing to battery core cannot be blocked, constantly having battery core to release high pressure-temperature can so the block such as breakthrough of gas foam fire continuously until the whole after-flame of battery, therefore battery system cannot be played effective extinguishing effect by routine fire procedure.
Utility model content
The purpose of this utility model is in that to provide a kind of battery system explosion-proof flame-retardant structure, with the problem solving to propose in above-mentioned background technology.
For achieving the above object, this utility model provides following technical scheme:
A kind of battery system explosion-proof flame-retardant structure, including multiple battery core assemblies, the outside of each battery core assembly is equipped with seal box, it is provided with sensor module in described seal box, sensor module includes temperature sensor and Smoke Sensor, described temperature sensor and Smoke Sensor and is all connected with control device；Utilize temperature sensor and Smoke Sensor detection seal box internal medium, and in real time data feedback is given control device；Described seal box connects fire extinguishing flow container by liquid-transport pipe-line, and liquid-transport pipe-line is provided with electromagnetic valve, electromagnetic valve connects control device, when controlling device and getting high temperature signal and smoke signal, then electromagnetic valve is opened, now the extinguishing fluid in fire extinguishing flow container flows in seal box, utilizes extinguishing fluid to realize the effect of starvation and cooling.
As further program of the utility model: described liquid-transport pipe-line is provided with electromagnetic pump, and electromagnetic pump connects control device, and the installation being therefore easy to fire extinguishing flow container is placed.
As further program of the utility model: the bottom of described seal box is provided with leakage fluid dram, and leakage fluid dram place is provided with draining solenoid valve, and draining solenoid valve connects control device.
Compared with prior art, the beneficial effects of the utility model are: this utility model is relative to existing technical pattern, overall security is greatly improved, do not result in the situation occurring mutually igniting between battery core simultaneously, therefore overall maintenance is more convenient, and the later stage is changed also very convenient.
Accompanying drawing explanation
Fig. 1 is the structural representation of a kind of battery system explosion-proof flame-retardant structure of this utility model.
In figure: 1-seal box, 2-battery core assembly, 3-sensor module, 4-fire extinguishing flow container, 5-liquid-transport pipe-line, 6-electromagnetic valve, 7-control device.
Detailed description of the invention
Below in conjunction with the accompanying drawing in this utility model embodiment, the technical scheme in this utility model embodiment is clearly and completely described, it is clear that described embodiment is only a part of embodiment of this utility model, rather than whole embodiments.Based on the embodiment in this utility model, the every other embodiment that those of ordinary skill in the art obtain under not making creative work premise, broadly fall into the scope of this utility model protection.
Refer to Fig. 1, in this utility model embodiment, a kind of battery system explosion-proof flame-retardant structure, including multiple battery core assemblies 2, the outside of each battery core assembly 2 is equipped with seal box 1, being provided with sensor module 3 in described seal box 1, sensor module 3 includes temperature sensor and Smoke Sensor, described temperature sensor and Smoke Sensor and is all connected with control device 7；Utilize temperature sensor and Smoke Sensor detection seal box 1 internal medium, and in real time data feedback is given control device 7；Described seal box 1 connects fire extinguishing flow container 4 by liquid-transport pipe-line 5, and liquid-transport pipe-line 5 is provided with electromagnetic valve 6, electromagnetic valve 6 connects control device 7, when controlling device 7 and getting high temperature signal and smoke signal, then electromagnetic valve 6 is opened, now the extinguishing fluid in fire extinguishing flow container 4 flows in seal box 1, utilizes extinguishing fluid to realize the effect of starvation and cooling.
Described liquid-transport pipe-line 5 is provided with electromagnetic pump, and electromagnetic pump connects control device 7, and the installation being therefore easy to fire extinguishing flow container 4 is placed.
The bottom of described seal box 1 is provided with leakage fluid dram, and leakage fluid dram place is provided with draining solenoid valve, and draining solenoid valve connects control device 7.
Operation principle of the present utility model is: in actually used process, owing to temperature sensor and Smoke Sensor detect seal box 1 internal medium, and in real time data feedback is given control device 7, simultaneously independent sealed mutually between battery core assembly 2, when controlling device 7 and getting high temperature signal and smoke signal, then electromagnetic valve 6 is opened, now the extinguishing fluid in fire extinguishing flow container 4 flows in seal box 1, extinguishing fluid is utilized to realize the effect of starvation and cooling, now owing to each battery core assembly 2 is separated from each other, therefore it also avoid influencing each other between battery core assembly.
