The components of the embodiments of the present application generally described and illustrated in the figures herein may be arranged and designed in a wide variety of different configurations. Thus, the following detailed description of the embodiments of the application, as presented in the figures, is not intended to limit the scope of the application, as claimed, but is merely representative of selected embodiments of the application. All other embodiments, which can be made by a person skilled in the art without making any inventive effort, are intended to be within the scope of the present application.
It should be noted that: like reference numerals and letters denote like items in the following figures, and thus once an item is defined in one figure, no further definition or explanation thereof is necessary in the following figures. Meanwhile, in the description of the present application, the terms "first", "second", and the like are used only to distinguish the description, and are not to be construed as indicating or implying relative importance.
The battery module is formed by combining a plurality of battery cells, the battery cells can be cylindrical batteries or soft package batteries, and the battery module is different from the cylindrical batteries in the discharging or charging process, the volume of the soft package batteries expands, the battery module formed by a plurality of soft package batteries is in the discharging process, if the soft package batteries expand in the discharging process, the soft package batteries can influence other structures of the fixed soft package batteries due to the volume increase after the expansion, so that the structure of the whole battery module is irreversibly damaged.
In view of this, as shown in fig. 1 to 4, an embodiment of the present application provides a swelling and absorbing device 200 for a pouch battery, which is applied to a battery module, wherein the battery module includes a plurality of pouch batteries 100 arranged in parallel, and the swelling and absorbing device is disposed between two adjacent pouch batteries 100. In one battery module, a plurality of soft pack batteries 100 may be fixed in groups by other fixing structures, and when the soft pack batteries 100 expand during discharging, the soft pack batteries 100 generally expand in the thickness direction, so that the thickness of the soft pack batteries 100 increases. In order to avoid structural damage to the battery module caused by expansion of the soft-pack battery 100, a certain gap can be reserved between two adjacent soft-pack battery 100 modules in the process of assembling the battery module, and the expansion absorbing device can be arranged in the gap between the two adjacent soft-pack batteries 100.
The expansion absorption device comprises an expansion absorption cavity 201 and an expansion absorption structure 202 arranged inside the expansion absorption cavity 201. The expansion absorption device in the embodiment of the present application may be made of a material with a relatively high thermal conductivity, for example, may be made of metal or alloy such as aluminum, iron, etc. Such expansion absorbing structure 202 can deform during the expansion process of the soft pack battery 100, and can absorb heat generated during the operation of the soft pack battery 100 through higher heat conduction performance, and can conduct the heat to other heat management devices or air, so as to realize heat management of the soft pack battery 100.
The expansion absorption structure 202 is disposed in the expansion absorption cavity 201, and the expansion absorption structure 202 may be made of soft materials, such as foam, and the like. When the expansion absorption structure 202 is deformed by extrusion, the expansion absorption cavity 201 can also change in volume correspondingly, so as to adapt to the deformed state of the expansion absorption structure 202. The shape of the expansion absorbing structure 202 can also be restored when no compression deformation of the expansion absorbing cavity 201 occurs. It will be appreciated that the expansion absorbent structure 202 may be an interference fit when fitted into the expansion absorbent cavity 201. That is, the thickness of the expansion absorption structure 202 is greater than the thickness of the inner cavity of the expansion absorption cavity 201, and since the expansion absorption structure 202 can be elastically deformed, after being installed into the expansion absorption cavity 201, the expansion absorption structure 202 with greater thickness can be abutted against the inner portion of the expansion absorption cavity 201, thereby realizing the position fixation.
In the embodiment of the present application, the expansion absorption chamber 201 includes two side plates 211 in contact with the pouch battery 100, and a plurality of connection plates 212 connecting the side plates 211. The expansion absorbing structure 202 may be fixedly connected to at least one of the side plates 211, and the expansion absorbing structure 202 is adapted to be elastically deformed when the distance between the side plates 211 is reduced.
The expansion absorption cavity 201 further comprises a liquid inlet 203 and a liquid outlet 204 which are arranged on the connecting plate 212, and the liquid inlet 203, the expansion absorption cavity 201 and the liquid outlet 204 form a liquid circulation channel. Because the expansion absorption cavity 201 can be arranged between two soft package batteries 100, in the working process of the soft package batteries 100, cooling liquid can be introduced into the expansion absorption cavity 201 through the liquid inlet 203 arranged on the connecting plate 212, and heat exchange between the expansion absorption cavity 201 and the soft package batteries 100 is utilized, so that the cooling liquid can take away heat generated by the soft board batteries, heat management of the soft package batteries 100 is realized, and the influence on the safety of the whole battery module due to overlarge heating value of the soft package batteries 100 is avoided.
In another embodiment, the thickness of the expanded absorbent structure 202 is less than or equal to the distance between the two side panels 211. The expansion absorption structure 202 may not be in interference fit with the expansion absorption cavity 201, and the expansion absorption cavity 201 may be more conveniently assembled when the thickness of the expansion absorption cavity 201 is smaller than or equal to the thickness of the inside of the expansion absorption cavity 201.
In an embodiment of the present application, the expansion absorbing structure 202 is an elastic block or a spring. The expansion absorption structure 202 absorbs the pressure applied to the expansion absorption chamber 201 during the expansion of the pouch cell 100 by undergoing elastic deformation, if the expansion absorption structure 202 is not provided inside the expansion absorption chamber 201, the pressure applied to the expansion absorption chamber 201 by the pouch cell 100 is greater if the expansion deformation occurring during the operation of the pouch cell 100 is greater. After the soft pack battery 100 stops working and its volume is restored to the original state, the expansion absorption chamber 201 may be difficult to restore due to the large deformation, so that it cannot be tightly attached to the soft pack battery 100. Through setting up elastic block or spring for even after the expansion absorption cavity 201 takes place deformation, elastic block or spring still can be after compressing to the original state, and then makes the expansion absorption cavity 201 can resume the original state after taking place deformation, avoids the expansion absorption cavity 201 to take place plastic deformation.
In another embodiment, the expansion absorption device further comprises a liquid supply device communicating with the liquid inlet 203 for supplying a heat management liquid into the expansion absorption chamber 201. And a flow meter provided at the liquid inlet 203 and/or the liquid outlet 204 for detecting the flow rate of the liquid flowing through the expansion absorption chamber 201. By providing the liquid supply means and the flowmeter, supply management of the thermal management liquid of the expansion absorption chamber 201 can be achieved.
In addition, the expansion absorption device further comprises a control chip connected with the flowmeter, and the control chip is used for controlling the liquid supply device to increase the supply flow rate when the flowmeter detects that the flow rate data is smaller than preset data. The control of the flow rate of the liquid in the expansion absorption device can be achieved by means of a control chip, in which case the flow rate of the liquid supplied by the liquid supply device, for example, into one of the expansion absorption chambers 201, is constant. During operation of the pouch battery 100, the volume of the pouch battery 100 expands, the expansion absorption cavity 201 disposed between two adjacent pouch batteries 100 in the battery module is compressed by the expanded pouch battery 100, and the internal volume of the compressed expansion absorption cavity 201 is reduced, so that the flow rate of the liquid flowing through the expansion absorption cavity 201 is reduced. At this time, the flow data detected by the flow meter will be smaller than the flow in the steady flow state, and the preset data may be preset according to the actual situation, where the preset data may be the flow data when the soft packet battery 100 is not expanded, so that when the flow data detected by the flow meter is smaller than the preset data, it indicates that the expansion absorption cavity 201 is deformed by extrusion, that is, the soft packet battery 100 is expanded. At this time, the control chip may control the flow rate supply device to increase the supply of the liquid, so that the flow rate of the thermal management liquid flowing through the expansion absorption cavity 201 is not reduced, so that the absorption capacity of the thermal management liquid in the expansion absorption cavity 201 to heat generated by the soft package battery 100 is not reduced, and timely heat management of the soft package battery 100 is ensured. In the embodiment of the present application, the thermal management liquid may be a refrigerant liquid, and the temperature of the soft pack battery 100 is reduced by the refrigerant liquid.
In another embodiment, as shown in fig. 5 and 6, each of the connection plates 212 includes a first plate 221 and a second plate 222 that are connected, where the first plate 221 is connected to one of the two side plates 211, and the second plate 222 is connected to the other side plate 211, and a plane in which the first plate 221 and the second plate 222 are located intersect. The expansion absorbing cavity 201 is required to deform under the expansion extrusion of the pouch battery 100, and since the space in the battery module is limited, the pouch battery 100 in the expanded state is easily damaged due to the limitation of the peripheral structure of the battery module, and the expansion absorbing structure 202 in the present application is designed to absorb the deformation generated when the pouch battery 100 expands. In order to enable the expansion absorbing structure 202 to deform faster when being pressed by the pouch cell 100, the connection plate 212 includes a first plate 221 and a second plate 222, and the first plate 221 and the second plate 222 form a certain included angle, when the side plate 211 is pressed by the pressing force, the pressing force is conducted to the connection plate 212, and the connection plate 212 formed by connecting the two plates can deform under the action of such pressing force. If the connection plate 212 is a single piece of plate, the connection plate 212 is disposed between the two side plates 211 under the same pressing force, so that the deformation speed of the connection plate 212 is smaller, and the deformation speed of the expansion absorption structure 202 is reduced.
In the embodiment of the application, the connecting plate 212 is arranged to be two plate bodies with an included angle, so that the connecting plate 212 is easier to deform under the action of extrusion force, and the expansion absorption cavity 201 can be correspondingly deformed faster under the expansion extrusion of the soft-packaged battery 100, thereby timely absorbing the expansion deformation of the soft-packaged battery 100.
In summary, in the expansion absorbing device provided by the embodiment of the application, the expansion absorbing structure 202 which can be arranged in the battery module and can deform is used for absorbing the deformation of the soft-packaged battery 100 caused by expansion, and simultaneously, the expansion absorbing structure 202 arranged in the expansion absorbing cavity 201 can absorb the expansion of the soft-packaged battery 100. In addition, the expansion absorption cavity 201 can circulate liquid by arranging the liquid inlet 203 and the liquid outlet 204, so that the heat management of the soft package battery 100 is realized, and the heat management effect of the soft package battery 100 module is improved. The expansion absorbing device in the embodiment of the application has a simple integral structure, can absorb the deformation of the soft package battery 100 module when the battery expands, can not damage the soft package battery 100 due to other structures of the battery module when the soft package battery 100 expands, and ensures the grouping safety of the soft package battery 100 module.
