In view of this, the present utility model provides a battery module, and fig. 1 to 8 are views illustrating an embodiment of the present utility model.
Referring to fig. 6 to 8, the battery module 1000 includes a mounting frame 1, a first battery cell module 2 and a second battery cell module 4, where the mounting frame 1 includes a first accommodating cavity 101 and a second accommodating cavity 102 that are disposed at intervals in a first direction; the first cell module 2 is fixed in the first accommodating cavity 101, a first pressure release cavity 3 is formed between the first cell module 2 and the mounting frame 1 at intervals, and when the first cell module 2 is in a thermal runaway state, gas in the first cell module 2 is discharged into the first pressure release cavity 3; the second cell module 4 is fixed in the second accommodating cavity 102, a second pressure release cavity 5 is formed between the second cell module 4 and the mounting frame 1 at intervals, and when the second cell module 4 is in a thermal runaway state, gas in the second cell module 4 is discharged into the second pressure release cavity 5; wherein the first pressure release cavity 3 and the second pressure release cavity 5 are arranged at intervals in the first direction and are located between the first cell module 2 and the second cell module 4.
In the embodiment of the present utility model, the first cell module 2 and the second cell module 4 are respectively installed on the installation frame 1 at intervals along the first direction, so as to realize a double-layer module structure of the battery module 1000, wherein the first pressure release cavity 3 and the second pressure release cavity 5 are respectively formed between the first cell module 2 and the installation frame 1, and between the second cell module 4 and the installation frame 1, when thermal runaway occurs in the first cell module 2 or the second cell module 4, gas in the first cell module 2 is discharged into the first pressure release cavity 3 and is discharged from the first pressure release cavity 3 into the external environment, and gas in the second cell module 4 is discharged into the second pressure release cavity 5 and is discharged from the second pressure release cavity 5 into the external environment, that is, when the first cell module 2 and the second cell module 4 have a relatively independent space when thermal runaway occurs in the battery module, the thermal runaway phenomenon occurs in the battery module 1000 can be avoided, and the thermal runaway phenomenon of the battery module 1000 can be prevented from occurring.
It will be appreciated that the first pressure relief cavity 3 and the second pressure relief cavity 5 may be formed when the first cell module 2 and the second cell module 4 are mounted to the mounting frame 1, respectively, so that the integration level of the whole battery module 1000 is higher, and the pressure relief cavity structure is not required to be formed on other parts of the battery pack.
Further, the opening directions of the first accommodation chamber 101 and the second accommodation chamber 102 are not limited, and it is easily conceivable that the opening directions of the first accommodation chamber 101 and the second accommodation chamber 102 determine the mounting directions of the first cell module 2 and the second cell module 4. In an embodiment of the present application, the first accommodating cavity 101 and the second accommodating cavity 102 may be opened toward a plane direction disposed at an angle to the first direction; in another embodiment of the present application, the first receiving chamber 101 and the second receiving chamber 102 may be opened toward the first direction.
In the embodiment of the present application, the specific direction of the first direction is not particularly limited, and the first direction may be any direction, such as an up-down direction, a left-right direction, a front-back direction, and the like.
Referring to fig. 2 to 3 and fig. 7 to 8, in an embodiment of the present application, the mounting frame 1 includes a frame 11 and a partition plate 12, the partition plate 12 is fixed in the frame 11, and the partition plate 12 separates the first accommodating cavity 101 and the second accommodating cavity 102; at least one pressure release channel 6 is also arranged on the frame 11; the first pressure release cavity 3 and the second pressure release cavity 5 are respectively communicated with the pressure release channel 6. The first core module 2 and the second core module 4 are installed in the frame 11 along the first direction, and the partition board 12 forms the first accommodating cavity 101 and the second accommodating cavity 102 in the frame 11 at intervals, and forms the first pressure release cavity 3 and the second pressure release cavity 5 with the first core module 2 and the second core module 4 at intervals. Meanwhile, the frame 11 is further provided with a pressure release channel 6 for communicating the first pressure release chamber 3 and the second pressure release chamber 5, so as to discharge the gas generated by thermal runaway to the external environment of the battery module 1000.
Referring to fig. 1 to 2 and fig. 7 to 8, it can be seen that the wall thickness of the portion of the frame 11 where the pressure release channel 6 is formed is greater than the wall thickness of the portion of the frame 11 where the pressure release channel 6 is not formed, so that the weight of the frame 11 can be effectively reduced while the safety and reliability of the portion of the frame 11 corresponding to the pressure release channel 6 can be ensured.
It should be noted that, since the plurality of pressure relief channels 6 are disposed on the frame 11, in order to ensure uniformity of the exhaust gas and improve the exhaust effect, in an embodiment of the present application, the plurality of pressure relief channels 6 are disposed at intervals along the circumferential direction of the frame 11, and on this basis, in an embodiment of the present application, one pressure relief channel 6 may be connected to the first pressure relief cavity 3 and the second pressure relief cavity 5 at the same time. In another embodiment of the present application, the first pressure relief cavity 3 and the second pressure relief cavity 5 may be respectively communicated with different pressure relief channels 6, where two adjacent pressure relief channels 6 may be respectively communicated with the first pressure relief cavity 3 and the second pressure relief cavity 5.
Further, the pressure relief channel 6 extends in the first direction; the frame 11 is provided with a first through hole 7 which is communicated with the first pressure relief cavity 3 and the corresponding pressure relief channel 6, and a second through hole 8 which is communicated with the second pressure relief cavity 5 and the corresponding pressure relief channel 6. The pressure relief channel 6 extends along the first direction, that is, the gas generated when the battery module 1000 is in thermal runaway is discharged along the first direction, and the first direction is taken as an up-down direction for illustration, referring to fig. 1 and 2, wherein the first cell module 2 in the battery module 1000 is disposed above the second cell module 4, and the gas outlet position of the pressure relief channel 6 is oriented downward.
Further, defining the inner diameter of the pressure relief channel 6 as D1; wherein, the D1 satisfies the following conditions: d1 And is more than or equal to 6mm. When the inner diameter of the pressure release channel 6 is smaller than 6mm, there may be a problem that the exhaust speed is too slow when the battery module 1000 discharges the thermal runaway gas, which easily results in that the internal pressures of the first pressure release chamber 3 and the second pressure release chamber 5 are too large to affect the safety of the structure of the battery module 1000, and it can be understood that, in order to increase the exhaust speed of the battery module 1000, the apertures of the first through hole 7 and the second through hole 8 may be set to be greater than or equal to 6mm.
Further, since the temperature of the thermal runaway gas is too high, in order to ensure that the frame 11 corresponding to the partial portion of the pressure relief channel 6 collapses due to the high temperature when the thermal runaway gas passes through the pressure relief channel 6, in an embodiment of the present application, referring to fig. 8, the mounting frame 1 further includes a bushing 13, and the bushing 13 is hollow and annular and is located on the pressure relief channel 6; wherein the heat resistance of the bushing 13 is greater than that of the frame 11. That is, by the design of the bushing 13, the thermal runaway gas is not in direct contact with the frame 11 in the region of the pressure release passage 6, and the thermal runaway gas is discharged from the inside of the bushing 13 so as not to affect the structural safety of the frame 11.
Still further, the material of the bushing 13 includes stainless steel, and the material of the mounting frame 1 includes aluminum alloy. Wherein the bushing 13 made of stainless steel has better high temperature resistance than the aluminum alloy.
Referring to fig. 5, in an embodiment, a heat insulation member 9 is disposed in the first pressure release chamber 3 and/or the second pressure release chamber 5. The heat insulation piece 9 can be a mica sheet, the mica sheet has good high temperature resistance and insulating property, the high temperature resistance can reach about 1300 ℃, and gas generated when the first cell module 2 or the second cell module 4 is out of control can be prevented from directly fusing through the mounting frame 1 through the design of the heat insulation piece 9.
Specifically, the first pressure release cavity 3 and the second pressure release cavity 5 are both internally provided with the heat insulation piece 9, the heat insulation piece 9 is close to the setting of the partition board 12, and can also be directly attached to the partition board 12, so as to avoid the situation that the thermal runaway gas in the first pressure release cavity 3 or the second pressure release cavity 5 is melted through the partition board 12, and can avoid the first core cell module 2 and the second core cell module 4 to be affected by each other in thermal runaway.
Referring to fig. 2 and 4, the first cell module 2 includes a first tray 21 and a first cell 22, the first tray 21 is fixed in the first accommodating cavity 101, a plurality of first pressure release holes 10 extending along the first direction are formed in the first tray 21, the plurality of first pressure release holes 10 are communicated with the first pressure release cavity 3, and the first cell 22 is correspondingly mounted at the first pressure release holes 10 and is arranged to cover the first pressure release holes 10, so that a thermal runaway area of the first cell 22 corresponds to the first pressure release holes 10; and/or, the second electric core module 4 includes a second tray 41 and a second electric core 42, the second tray 41 is fixed in the second accommodating cavity 102, a plurality of second pressure release holes 14 extending along the first direction are formed on the second tray 41, a plurality of second pressure release holes 14 are communicated with the second pressure release cavity 5, and the second electric core 42 is correspondingly installed at the second pressure release holes 14 and covers the second pressure release holes 14, so that a thermal runaway pressure release area of the second electric core 42 corresponds to the second pressure release holes 14. The first tray 21 or the second tray 41 may be respectively provided with a plurality of first electric cells 22 and a plurality of second electric cells 42, which is illustrated by thermal runaway of one of the first electric cells 22 on the first tray 21, after thermal runaway of one of the first electric cells 22 on the first tray 21 occurs, the thermal runaway gas discharged from the first electric cells 22 directly enters the first pressure release hole 10 into the first pressure release cavity 3, and is discharged into the external environment of the battery module 1000, that is, the thermal runaway gas discharged from the first electric cells 22 does not enter the mounting area of the first tray 21, and the plurality of first electric cells 22 do not interfere with each other due to thermal runaway.
Further, referring to fig. 7 and 8, when the first battery cell 22 or the second battery cell 42 is respectively mounted on the first tray 21 and the second tray 41, the first battery cell 22 or the second battery cell 42 is fixed by the structural adhesive 18, and an insulating layer is disposed at a contact position between the first battery cell 22 or the second battery cell 42 and the first tray 21 and the second tray 41.
