Abstract

The invention discloses a self-extinguishing battery which comprises a shell. A battery pack is disposed in the inner cavity of the shell, a fire-extinguishing bag used for extinguishing fire of the battery pack is arranged above the battery pack, the fire-extinguishing bag is provided with a bag body made of plastics, and a fire-extinguishing agent is sealed in the bag body of the fire-extinguishing bag. The self-extinguishing battery is simple in structure, reasonable in design and convenient in operation; when a certain cell of the battery pack catches fire or explodes, temperature of fire or impact force of explosion destroys the bag body of the fire-extinguishing bag so as to have the fire-extinguishing agent in the fire-extinguishing bag drained to perform fire extinguishment on the entire battery pack, so that the entire battery pack is less prone to explosion, security level of an automobile equipped with the battery pack is improved, and spontaneous ignition of the automobile is effectively prevented.

Description

Self-extinguishing battery
Technical field
The present invention relates to cell art, especially a kind of self-extinguishing battery.
Background technology
Set of cells is made up of the battery core of multiple rows of multiple row, and usual battery core is not provided with fire-fighting equipment, only some circulation fire The facility of gas, so, when a certain battery core explosion time, easily cause battery bulk temperature too high and cause the chain of rings of other battery cores quick-fried Fried, and then the blast of whole set of cells is damaged, affect bigger.
Summary of the invention
The technical problem to be solved in the present invention is: overcome the deficiencies in the prior art, it is provided that a kind of simple in construction, extinguishing property Good self-extinguishing battery.
The technical solution adopted for the present invention to solve the technical problems is: a kind of self-extinguishing battery, including housing, described Housing cavity is placed with set of cells, and described set of cells is arranged over the fire extinguishing bag for putting out a fire to set of cells, and described fire extinguishing bag has There is bag, in the bag of described fire extinguishing bag, be packaged with extinguishing chemical.
Further, the bag of described fire extinguishing bag is made of plastics.
Further, the bag of described fire extinguishing bag by polyethylene (PE) or polyethylene terephthalate (PET) or Person's polystyrene (PS) is made.
Further, the extinguishing chemical in described fire extinguishing bag is water or dry powder or alkyl halide or heptafluoro-propane.
Further, it is coated with upper cover plate above described fire extinguishing bag.
The invention has the beneficial effects as follows: present configuration is simple, reasonable in design, easy to operate, in some of set of cells Catching fire or explosion time occurs in battery core, and the bag of fire extinguishing bag is destroyed by the temperature of fire or the impulsive force of blast so that fire extinguishing bag In extinguishing chemical release, whole set of cells is put out a fire, the most whole set of cells be not easy produce blast, improve install battery The safe class of the automobile of group, effectively prevents self-burning of vehicle.
Accompanying drawing explanation
The present invention is further described below in conjunction with the accompanying drawings.
Fig. 1 is the split schematic diagram of the present invention;
Fig. 2 is the assembling schematic diagram of the present invention.
Wherein: 1. upper cover plate, 2. fire extinguishing bag, 3. set of cells, 4. housing.
Detailed description of the invention
Presently in connection with accompanying drawing, the present invention is further illustrated.These accompanying drawings are the schematic diagram of simplification only with signal side The basic structure of the formula explanation present invention, therefore it only shows the composition relevant with the present invention.
Self-extinguishing battery as shown in Figure 1 and Figure 2, including housing 4, described housing 4 inner chamber is placed with set of cells 3, described Set of cells 3 is arranged over the fire extinguishing bag 2 for putting out a fire to set of cells 3, and described fire extinguishing bag 2 has bag, the bag of described fire extinguishing bag 2 Internal it is packaged with extinguishing chemical.
The bag of described fire extinguishing bag 2 is made of plastics.Such as, the bag of described fire extinguishing bag 2 by polyethylene or gathers benzene Naphthalate or polystyrene are made.Preferably, the bag of described fire extinguishing bag 2 is made up of polyethylene.
Extinguishing chemical in described fire extinguishing bag 2 is water or dry powder or alkyl halide or heptafluoro-propane.Extinguishing chemical is preferably water.
It is coated with upper cover plate 1 above described fire extinguishing bag 2.
This self-extinguishing battery structure is simple, and reasonable in design, easy to operate, some battery core in set of cells occurs The bag of fire extinguishing bag is destroyed by fire or explosion time, the temperature of fire or the impulsive force of blast so that the extinguishing chemical in fire extinguishing bag Releasing, put out a fire whole set of cells, the most whole set of cells is not easy to produce blast, improves the automobile of installation set of cells Safe class, effectively prevents self-burning of vehicle.
With the above-mentioned desirable embodiment according to the present invention for enlightenment, by above-mentioned description, relevant staff is complete Entirely can carry out various change and amendment in the range of without departing from this invention technological thought.The technology of this invention The content that property scope is not limited in description, it is necessary to determine its technical scope according to right.
