Specific embodiment
Embodiments of the present invention are described further with reference to the accompanying drawing.
The specific embodiment 1 of battery modules of the invention, as shown in Figure 1, battery modules include battery modules fixed charge method end plate 1
And the battery unit 2 being installed between two battery modules fixed charge method end plates 1, battery unit 2 include battery case 21 and are fixed on electricity
Battery cover board 22 on pond shell 21, battery cover board 22 is equipped with positive terminal 23 and negative terminal 24, such as Fig. 4 institute
Show, battery unit explosion-proof valve 25,25 structure of battery unit explosion-proof valve are equipped between positive terminal 23 and negative terminal 24
At battery unit blast resistance construction, the pressure in battery unit 2 carries out pressure release by battery unit explosion-proof valve 25 more than after setting value.
As shown in Figures 2 to 4, battery modules further include the battery fire extinguishing component of strip, and battery fire extinguishing component includes battery
Fire extinguishment container 3, battery fire extinguishment container 3 have with the one-to-one extinguishing chemical accommodating chamber 31 of battery unit 2, in extinguishing chemical accommodating chamber
Contain extinguishing chemical.It is equipped in the cavity wall of each extinguishing chemical accommodating chamber 31 for when extinguishing chemical accommodates cavity pressure and reaches setting value
Open the accommodating chamber explosion-proof valve 32 of pressure release and for being correspondingly arranged with the battery unit explosion-proof valve 25 on battery unit in battery
The battery anti-explosion valve 33 of pressure release, battery unit of the battery anti-explosion valve 33 towards battery unit 2 are opened when unit explosion-proof valve 25 is opened
Explosion-proof valve 25 is arranged.Accommodating chamber explosion-proof valve 32 in the present embodiment constitutes the receiving being arranged in the cavity wall of extinguishing chemical accommodating chamber 31
Chamber blast resistance construction, battery anti-explosion valve 33 constitute the battery anti-explosion structure being arranged in the cavity wall of extinguishing chemical accommodating chamber 31.
As shown in Figure 5 and Figure 8, one of total by adjacent extinguishing chemical accommodating chamber there are two types of accommodating chamber explosion-proof valves 32
Accommodating chamber explosion-proof valve, shared accommodating chamber explosion-proof valve are pair for being connected to corresponding two extinguishing chemicals accommodating chamber when opening pressure release
Interior accommodating chamber explosion-proof valve 321, each extinguishing chemical accommodating chamber 31 all have internal accommodating chamber explosion-proof valve 321.It is internal in the present embodiment
Explosion-proof 321 valve of accommodating chamber is formed in the internal accommodating chamber blast resistance construction for being connected to corresponding two extinguishing chemicals accommodating chamber when opening pressure release.
Another is when opening pressure release that the external accommodating chamber being connected to outside extinguishing chemical accommodating chamber 31 and battery fire extinguishment container 3 is explosion-proof
Valve 322, external accommodating chamber explosion-proof valve constitute external accommodating chamber blast resistance construction.Adjacent extinguishing chemical accommodating chamber 31 has shared appearance
Receive cavity wall, shared accommodating chamber explosion-proof valve 32 is arranged in the shared receiving cavity wall of adjacent extinguishing chemical accommodating chamber 31.This implementation
In example, adjacent extinguishing chemical accommodating chamber 31 all has internal accommodating chamber explosion-proof valve 321, and extinguishing chemical accommodating chamber 31 is elongated side by side
Arrangement, external accommodating chamber explosion-proof valve 322 are set in the cavity wall of extinguishing chemical accommodating chamber 31 at both ends.
As shown in Figure 5 and Figure 6, the extinguishing chemical accommodating chamber 31 in the present embodiment is square, and wherein battery anti-explosion valve 33 is arranged

Processing.When the pressure for the fluid gone out by battery unit explosion-proof valve 25 is excessive, the pressure in extinguishing chemical accommodating chamber 31 is greater than
When the cracking pressure of accommodating chamber explosion-proof valve 32, the accommodating chamber explosion-proof valve 32 of battery fire extinguishment container 3 is opened, to extinguishing chemical accommodating chamber 31
Carry out pressure release.When pressure is sufficiently large, the accommodating chamber explosion-proof valve 32 of extinguishing chemical accommodating chamber 31 is all opened, and all extinguishing chemicals hold
Chamber 31 of receiving is connected, eventually by towards 32 discharge pressure of accommodating chamber explosion-proof valve outside battery fire extinguishment container 3.In insufficient pressure
To wash open towards the accommodating chamber explosion-proof valve 32 outside battery fire extinguishment container 3, and single extinguishing chemical accommodating chamber 31 is difficult to meet battery
When the pressure release demand of unit 2, it is possible that several adjacent extinguishing chemical accommodating chambers 31 accommodating chamber explosion-proof valve 32 open with
The case where realizing connection, at this time the corresponding battery unit 2 of extinguishing chemical in multiple extinguishing chemical accommodating chambers 31 carry out fire extinguishing or
Fire prevention processing.If all extinguishing chemical accommodating chambers 31 are not able to satisfy battery unit pressure release demand, the external receiving in end
Chamber explosion-proof valve is opened, and to battery fire extinguishment container outside pressure release, is also likely to be present internal accommodating chamber explosion-proof valve certainly and is not beaten completely
Open, directly by external accommodating chamber explosion-proof valve pressure release the case where.Same principle, it is also possible to multiple extinguishing chemical accommodating chambers 31 occur
Two or more corresponding battery units 2 are put out a fire or are prevented fires the case where handling.
As shown in Figure 1 and Figure 7, the battery fire extinguishment container 3 in the present embodiment is string configuration, and width dimensions are less than electricity
The distance between positive terminal 23 and negative terminal 24 on pool unit 2, battery fire extinguishment container 3 is fixed on each when use
Between the positive terminal 23 and negative terminal 24 of battery unit 2, the both ends of battery fire extinguishment container 3 are equipped with fixation hole
35, it is fixed on the battery modules fixed charge method end plate 1 at battery modules both ends by fixation hole 35, after fixed, battery fire extinguishment container 3
