Specific embodiment
With reference to the accompanying drawing to the specific reality of battery case of the invention, safety battery, battery modules, battery case and vehicle
The mode of applying is described further.
The specific embodiment one of battery modules of the invention, as shown in Figure 1 to Figure 2, battery modules include along the longitudinal direction
Arrange that common batteries 10 and safety battery 11, safety battery 11 include battery case 101 and battery cover board 1, battery case 101 has
Having top is the battery core chamber 5 of uncovered structure, also has the extinguishing chemical chamber 6 positioned at 5 side of battery core chamber, battery core chamber 5 and extinguishing chemical chamber 6
It is separated by partition panel 9, partition panel 9 constitutes partition portion.The extinguishing chemical chamber 6 of safety battery 11 is located at the front side of battery core chamber 5.Partition
Plate 9, which is equipped with, to be opened when 5 internal pressure of battery core chamber reaches setting pressure so that battery core chamber 5 is connected to pressure release with extinguishing chemical chamber 6
Battery core explosion-proof valve 8,6 cavity wall of extinguishing chemical chamber are equipped with for opening when 6 internal pressure of extinguishing chemical chamber reaches setting pressure to peace
The outer explosion-proof valve 7 of pressure release outside full battery.Battery core explosion-proof valve 8 constitutes battery core blast resistance construction, and outer explosion-proof valve 7 constitutes outer explosion-proof knot
Structure.The safety battery does not need to increase fire monitoring device when in use, by the extinguishing chemical that the circumferential side of battery core chamber 5 is arranged in
Chamber 6, battery core explosion-proof valve 8 and outer explosion-proof valve 7 realize the pressure release and fire extinguishing of battery.With to the induction of 101 internal pressure of battery case
Accurately, the rapid accurately effect of extinguishing device starting, effectively prevents the cell safety problem as caused by faults of monitoring system.
When overcharging, causing 5 internal pressure of battery core chamber to reach setting pressure under the abuse item such as over-discharge, setting is separating battery core
The opening of battery core explosion-proof valve 8 on plate 9 makes battery core chamber 5 be connected to pressure release with extinguishing chemical chamber 6, prevents battery core from the safe things such as explosion occur
Therefore;When 6 internal pressure of extinguishing chemical chamber reaches setting pressure, the outer explosion-proof valve 7 that extinguishing chemical chamber 6 is arranged in, which is opened, carries out pressure release,
It is stored in the extinguishing chemical inside extinguishing chemical chamber 6 simultaneously to spray under the promotion of 6 internal pressure of extinguishing chemical chamber, realizes in safety battery
The fire extinguishing of portion or outside and fire behavior inhibit, and prevent battery from the safety accidents such as kindling, explosion occur.
With battery core chamber 5 is encircled into, battery case 101 and partition panel 9, which are matched, is encircled into fire extinguishing for battery case 101 and partition panel 9
Agent chamber 6.When processing battery case 101, whole battery case 101 need to be first only processed, then inside battery case 101
The battery case 101 with battery core chamber 5 and extinguishing chemical chamber 6 can be processed by increasing partition panel 9.8 number of battery core explosion-proof valve is one
It is a, close to the top layout of battery core chamber 5;Outer 7 number of explosion-proof valve is two, is arranged close to the bottom of extinguishing chemical chamber 6.Battery core is explosion-proof
The cracking pressure of valve 8 is less than the cracking pressure of outer explosion-proof valve 7.Battery core explosion-proof valve 8 and outer explosion-proof valve 7 are arranged in battery case 101
Different parts up and down, have the function of facilitating using high pressure in battery core as extinguishing chemical boosting power.When battery core cavity pressure exists
8 cracking pressure of battery core explosion-proof valve is increased under abnormal conditions, and extinguishing chemical chamber internal pressure is not up to outer 7 cracking pressure of explosion-proof valve
When, the cracking pressure of battery core explosion-proof valve 8 is less than the cracking pressure of outer explosion-proof valve 7, and battery core chamber can be realized by battery core explosion-proof valve 8
Pressure release inside 5, then outer explosion-proof valve 7 will not be opened, and save extinguishing chemical and ensure the safety of battery.
It is uncovered structure at the top of extinguishing chemical chamber 6, the top of battery core chamber 5 is also uncovered structure, and battery cover board 1 is simultaneously to fire extinguishing
Agent chamber and battery core chamber are sealed.Battery cover board 1 be equipped be connected with battery core output terminal 2, electrolyte filler port 3 and with go out
The extinguishing chemical filler port 4 being connected inside fiery agent chamber 6.Electrolyte filler port 2 is used for the filling of battery unit electrolyte inside, has filled
It is closed after, extinguishing chemical filler port 4 is used for the filling of extinguishing chemical, has the effect of that filling is easy to operate.Using existing skill
After art completes the production of battery core unit, conductive material welding is carried out to battery core, 1 laser welding process of battery cover board is welded
Sealing.Then electrolyte injection is carried out to battery core chamber 5 by electrolyte filler port 3 under the environmental condition of drying shed, completes to survey
Sealing sealing is carried out to injecting electrolytic solution hole 3 after examination.It is gone out by extinguishing chemical filler port 4 to extinguishing chemical chamber 6 in drying shed
Fiery agent injection, and sealing sealing is carried out to extinguishing chemical liquid injection hole 4.
The extinguishing chemical in extinguishing chemical chamber 6 in the present embodiment is given birth to using Shiji Lianbao Fire Fighting New Technology Co., Ltd., Beijing
