The battery module solves the problem that the existing module structure can bring out electrolyte to pollute a circuit board at a top cover or pollute other batteries, so that potential safety hazards are caused.
Referring to fig. 1, the side wall of the housing 21 includes a first side wall overlapping with the adjacent battery cells and a second side wall far away from the adjacent battery cells, the first side wall and the second side wall are connected to each other to enclose with the bottom wall to form a containing cavity, and in general, the pressure release valve 23 of the battery cell is disposed on the second side wall to prevent the pressure release valve 23 from being invalid due to expansion of the battery cell, at this time, the containing space is at least disposed on the second side wall where the pressure release valve 23 is located. Further, in order to increase the volume of the accommodating space, the accommodating space may be further disposed on the first side wall and/or the bottom wall of the housing 21 and communicate with the accommodating space on the second side wall, and at this time, an L-shaped or U-shaped accommodating portion (refer to fig. 3 and 4) may be formed on the peripheral side of the battery cell to accommodate more electrolyte 4. In order to further increase the accommodating space, the accommodating space may also extend to the second side wall corresponding to the second side wall where the pressure release valve 23 is located, and at this time, a groove-shaped (not shown) accommodating portion 3 may be formed on the peripheral side of the battery cell.

It should be noted that the number of the pressure release valves 23 may be one, two, or even 3, and may be disposed on the second side wall or the bottom wall or disposed on the second side wall and the bottom wall respectively, so long as they are disposed far from the first side wall and the top wall.

In this embodiment, the housing space has a first opening 31 facing the relief valve 23 and communicating with the opening thereof, and a second opening 32 provided away from the housing wall surface. When the pole 22 is disposed on the top wall of the housing, the second opening 32 is opened on the upper end surface of the accommodating portion 3 located on the side wall of the housing, so as to release the pressure in the accommodating space. By arranging the second opening 32 on the upper end surface, the volume of the accommodating space is ensured, and the accommodating volume is prevented from being reduced due to the too low height of the second opening 32.
In an alternative embodiment, the pole 22 and the relief valve 23 are arranged on the same side wall of the housing 21, the height of the relief valve 23 and the housing 3 communicating with the relief valve 23 is lower than the height of the pole 22, wherein the second opening 32 of the housing is arranged towards the side wall away from the pole 22. By lowering the height of the relief valve 23 and the housing part 3, contact with the pole 22 is avoided, and at the same time, the second opening 32 is arranged away from the pole 22, i.e. perpendicular to the side wall where it is located, so as to prevent the electrolyte 4 from being sprayed and sputtered onto the pole 22 to cause pollution.
The utility model also provides a battery, which comprises a collecting box (not shown in fig. 8), a conducting pipeline 5 and the battery module, wherein one end of the conducting pipeline 5 is communicated with the bottom of the accommodating part 3, and the other end of the conducting pipeline 5 is communicated with the collecting box so as to collect leakage liquid. The conducting pipeline 5 is connected to the bottom of the accommodating part 3 so as to facilitate the total elimination of the collected electrolyte 4 and avoid the deposition of the liquid.
Since the electrolyte 4 is toxic and corrosive, a collection tank is provided to accommodate the discharged electrolyte 4, avoiding its influence on other devices.
As shown in fig. 8, a conduction port may be provided for each of the housing portions 3 of the battery cells of the battery cell group 2, and the conduction port may be connected to the conduction pipe 5 so as to discharge the electrolyte 4, and at this time, any amount of the electrolyte 4 may be safely and independently discharged. In this embodiment, the conducting port may be disposed at one end of the accommodating portion 3, so that the conducting pipeline 5 is disposed at the same side of the battery unit group 2, and arrangement of the conducting pipeline 5 is simplified. The second opening 32 may be a through-hole, and may be connected to the through-pipe 5 to discharge the leakage liquid. Further, the conduction pipe 5 is provided with a check valve 6 that is one-way conducted from the housing 3 to the collection tank to prevent the backflow of the leaked electrolyte 4.
The present application is specifically described below by way of examples:
example 1:
referring to fig. 1 and 2, the relief valves 23 may be disposed on the side walls of the plurality of housings 21 in the same direction, that is, the relief valves 23 are disposed toward the same direction, as shown in fig. 1, and the accommodating portion 3 is disposed on the side wall where the relief valves 23 are disposed, so as to realize communication between the relief valves 23 and the accommodating portion 3. Of course, the pressure release valve 23 may be disposed on the side walls of the plurality of housings 21 facing in different directions, and the accommodating portion 3 may be disposed on the side walls of the housings 21 facing in different directions (not shown), so long as the pressure release valve 23 and the accommodating portion 3 are disposed on the same side wall, and the disposition in different directions increases the space volume of the entire battery module and reduces the energy density compared to the disposition in the same direction. The housing portion 3 is a housing mechanism covered on the pressure release valve 23, and forms a housing space with the side wall to house the electrolyte 4. The shape of the housing portion 3 is not limited as long as the entire region of the relief valve 23 that bursts after burst can be shielded and housed.
In this embodiment, since the electrode 22 of the battery needs to be electrically connected to the outside, the electrode 22 will be corroded by touching the electrolyte 4, resulting in poor contact or damage of the electrode 22, so the pressure release valve 23 is disposed away from the surface of the housing 21 where the electrode 22 is located, and the possibility of contact between the electrolyte 4 and the electrode 22 after explosion is reduced. The side wall of the housing 21 includes a first side wall corresponding to an adjacent battery cell and a non-adjacent second side wall, and in general, the pole 22 is disposed on the top wall of the housing 21 (as shown in fig. 1), so in this embodiment, the pressure release valve 23 may be disposed on the second side wall of the housing 21, and the accommodating portion 3 is also disposed on the second side wall, so as to play a role in buffering, and avoid damage to the battery cell caused by vibration between the case 1 and the battery cell.
Because the expansion surface of the battery is mainly arranged on the first side wall in the use process, the pressure release valve 23 is not arranged on the expansion surface of the battery to prevent the pressure release valve 23 from failing, but the containing part 3 can be arranged on the expansion surface of the battery, so that the containing part 3 can be used as an expansion space, a heat insulation pad can be saved, and the heat insulation of two adjacent battery monomers is realized through the containing part 3 arranged on the first side wall, so that the transmission of thermal runaway from the uncontrolled battery to surrounding batteries is blocked, and the damage to other batteries and the incidental damage effect are reduced.
In the present embodiment, the relief valve 23 may be disposed below 1/2 of the height of the side wall of the housing 21, and the height of the accommodating portion 3 is greater than 1/2 of the height of the side wall of the housing 21, i.e., the height of the accommodating portion 3 is disposed above 1/2 of the height of the side surface of the housing 21. By the staggered arrangement of the height of the pressure release valve 23 and the containing part 3, the whole volume of the containing space can be increased, so that the leaked electrolyte 4 can be contained in the containing space for a long time, and the situation that the electrolyte 4 cannot enter the containing part 3 to leak directly is avoided.
The accommodating part 3 is covered on the pressure release valve 23 and is connected with the side wall where the pressure release valve 23 is located, the accommodating space is provided with a first opening 31 facing the pressure release valve 23, the first opening 31 is communicated with the opening of the pressure release valve 23 to form a space for covering the periphery of the pressure release valve 23 so as to accommodate electrolyte 4 flowing out after explosion, and the pressure release valve 23 is arranged below the side wall, so that the released electrolyte 4 can be prevented from flowing into the accommodating part 3 too quickly and not directly rushing out of the accommodating part 3. The accommodating portion 3 has a second opening 32 far from the first opening 31, so that the electrolyte 4 flows into the accommodating space from the first opening 31 and then flows out from the second opening 32, and generally, the second opening 32 may be disposed at the top end of the accommodating portion 3 (as shown in fig. 2) to increase the volume of the accommodating space and accommodate more leaked electrolyte 4. The height and width of the housing portion 3 are not limited as long as the relief valve 23 can be covered. Alternatively, the highest point of the accommodating portion 3 is smaller than or equal to the height of the side wall of the housing 21, and the width thereof is smaller than or equal to the width of the side wall of the housing 21. In order to increase the volume of the accommodating portion 3 as much as possible, reduce the thickness thereof, and increase the overall energy density, the width of the accommodating portion 3 is equal to the width of the side face, and the highest point is equal to the height of the side wall.
In this embodiment, when the electrolyte 4 is excessive, there is still a problem that the electrolyte 4 flows out, and the flowing electrolyte 4 still has a problem of contaminating the pole 22 at the top of the battery cell, so that the highest point of the accommodating portion 3 is lower than the highest point of the side wall of the housing 21, so as to increase the distance between the second opening 32 of the accommodating space and the pole 22, and even if the electrolyte 4 flows out from the second opening 32, the electrolyte can be far away from the pole 22. That is, the highest point of the housing portion 3 is smaller than the height of the side wall of the case 21, and even if the electrolyte 4 flows out, it is lower than the top wall of the battery cell, thereby reducing the possibility of contact with the pole 22.
In this embodiment, the accommodating portion 3 is made of a rigid insulating material, and may be PVC (polyvinyl chloride), PE (polyethylene), PP (polypropylene), PET (polyethylene terephthalate), PC (polycarbonate), or the like, and has thermoplastic properties, and after being molded, the accommodating portion may be directly adhered to a wall surface where the pressure release valve 23 is located, so as to accommodate the flowing electrolyte 4, and prevent the electrolyte from polluting other batteries. The material of the housing portion 3 also has corrosion resistance, and corrosion of the electrolyte 4 is avoided. The larger the accommodating space of the accommodating portion 3, the more the electrolyte 4 can be accommodated therein.
Example 2:
referring to fig. 3, the pressure release valve 23 is disposed on one side wall of the battery cell, and the accommodating portion 3 is covered on one side wall of the housing 21 and the bottom wall of the housing 21 to form a communicating accommodating space between the side wall and the bottom wall of the battery cell. Compared with embodiment 1, the volume of the accommodating space is increased.
Example 3:
referring to fig. 4, two pressure release valves 23 are respectively disposed on two sidewalls of the housing 21, and the accommodating portion 3 is covered on two second sidewalls of the housing 21 and the bottom wall of the housing 21 to form an accommodating space between the second sidewalls and the bottom wall of the battery cell, so as to increase the accommodating space. Of course, the number of the pressure release valves 23 may be one, and the purpose of this embodiment is to increase the volume of the accommodating space of the accommodating portion 3, and the two second side walls and the bottom wall are each provided with an accommodating space that is mutually communicated.
Example 4:
as shown in fig. 5, since the relief valve 23 and the pole 22 are disposed on the same wall surface, the electrolyte 4 in the housing 3 is likely to contaminate the pole 22, so that the height of the relief valve 23 is smaller than the height of the pole 22, which may be less than 1/2 of the height of the side wall of the housing 21 to be away from the pole 22, and the height of the housing 3 is also smaller than the height of the pole 22, at this time, the second opening 32 may be disposed on the wall surface of the housing 3 away from the side wall and from the pole 22 to prevent the leaked electrolyte 4 from being sprayed upward to directly contact the pole 22.
Example 5:
as shown in fig. 6, the pressure release valve 23 is provided only on the bottom wall of the battery cell, and the housing portion 3 may be covered on the side wall of the housing 21 and the bottom wall of the housing 21 to form a communicating housing space between the side wall and the bottom wall of the battery cell. At this time, the pressure relief of the battery is realized by the accommodation space covering the bottom wall and the side wall. At this time, the second opening 32 is still formed at the upper end of the accommodating portion 3, so as to increase the volume of the accommodating space.
Example 6:
as shown in fig. 7 and 8, compared with embodiment 5, the accommodating space is only provided on the bottom wall, and by providing the relief valve 23 on the bottom wall, the distance between the relief valve 23 and the top wall pole 22 can be increased, and the risk of contaminating the pole 22 can be reduced. At this time, the leaked electrolyte 4 can be discharged through the conduit 5, and the volume of the storage space is not limited. Further, a check valve 6 may be provided on the conduction pipe 5 to prevent the discharged electrolyte 4 from flowing back into the battery cell.
