A first aspect according to an embodiment of the present application provides a battery pack, and the structure and operation principle of the battery pack will be described in detail with reference to fig. 1 to 8.
According to the battery pack provided by the embodiment of the application, the battery pack is used for a vehicle, the vehicle is provided with an installation area for installing the battery pack, and the battery pack comprises a box body, a plurality of single batteries and a compensation component. In an embodiment, the case includes a first wall portion and a second wall portion disposed opposite to each other in the first direction, and the case further includes a side portion disposed between the first wall portion and the second wall portion.
In an embodiment, the plurality of unit cells are disposed in a space defined by the first wall portion, the second wall portion, and the side portion. In an embodiment, the compensation assembly comprises a compensation mounting portion and a compensation support portion, the compensation mounting portion is configured to be detachably connected with the case, the compensation support portion is located on a side of the compensation mounting portion away from the case, the compensation support portion is configured to be capable of being located close to the case and away from the case, and the compensation support portion is configured to be supported in the mounting area.
Therefore, according to the battery pack provided by the embodiment of the application, the compensation component is detachably connected to the box body, when the battery pack has the problems of loosening and shaking at the position in the installation area of the vehicle, the compensation support part of the compensation component can be supported in the installation area to provide effective positioning for the battery pack, so that the loosening and shaking amplitude of the battery pack in the installation area can be compensated, the installation tightness of the battery pack is improved, and the influence on the stability of power transmission caused by shaking in the running process of the vehicle of the battery pack is avoided.
According to the battery pack provided by the embodiment of the application, the battery pack can comprise the switching member, the switching member can be detachably connected with the first wall part and the second wall part, the switching member can span the side part and is detachably connected with the side part, the switching member can be provided with the compensation connection area, and the compensation installation part is detachably connected with the compensation connection area.
In this way, according to the battery pack provided by the embodiment of the application, the battery pack is detachably connected with the first wall part, the second wall part and the side part through the switching member, so that the box body is detachable as a whole, and the replacement of structures such as the first wall part, the second wall part and the side part in the box body is facilitated. Meanwhile, the switching member also provides a compensation connection area of the compensation installation part, which is equivalent to multiplexing the switching member, namely, the switching member has the function of providing an installation position for the compensation assembly while serving as a connection structure forming the box body, so that the multiplexing of components is realized, which is beneficial to the compact structure of the battery pack.
In addition, according to the battery pack provided by the embodiment of the application, the switching component also plays a role in isolation. Here, as an example, the adapter member avoids directly connecting the compensation assembly to the case, thereby advantageously increasing the insulation performance of the battery pack with respect to the external environment, in particular the mounting area of the battery pack that the vehicle has. That is, the use of the switching member prevents the connection member such as a screw from being directly inserted into the interior of the battery pack, and such connection member not only does not have insulation properties due to its own metal material, but may cause the connection member to be too tightly spaced from the unit cells in the battery pack when being excessively inserted into the case. In addition, when the battery pack is impacted by external force, the distance between the single battery in the battery pack and the connecting piece is not easy to keep, in other words, the switching component plays a role in preventing the connecting piece from being excessively penetrated into the box body to reduce the electrical insulation performance, and buffering can be formed between the single battery and the connecting piece.
According to the battery pack provided by the embodiment of the application, the compensation assembly can comprise the compensation fastening member, the compensation fastening member can be arranged on the compensation installation part and the switching member in a penetrating manner, and the compensation fastening member can be detachably connected to the side part. In the embodiment, it is equivalent to connecting the compensation installation part and the switching member to the side of the case of the battery pack all through the same connection structure, which effectively reduces the complexity of the battery pack.
According to the battery pack provided by the embodiment of the application, the number of the switching members can be multiple, and at least part of the switching members are provided with the compensation components, wherein at least part of the switching members are at least two, so that the at least two compensation components can compensate the loosening and shaking space of the battery pack in a more effective manner, for example, when the compensation directions of the two compensation components are crossed, the battery pack can be ensured to be freely adjusted in the horizontal plane, and therefore, any allowance compensation is obtained, and the compensation allowance required by the combination can be adjusted when the two compensation directions are crossed.
According to the battery pack provided by the embodiment of the application, the battery pack further comprises an external terminal and a switching terminal. In an embodiment, the external terminal is electrically connected to the plurality of unit cells. The switching terminal can be arranged at intervals with the external terminal and is electrically connected with the external terminal, and the switching terminal can change the position in a staggered mode with the external terminal, so that the position of the terminal which is electrically connected with the outside of the battery pack can be adjusted through the switching terminal, and the position of the switching terminal of the battery pack can be finely adjusted according to the actual situation after the battery pack is arranged in the installation area, and the adaptability of the battery pack is further improved.
According to the battery pack provided by the embodiment of the application, the battery pack further comprises a transfer circuit, wherein the transfer circuit is electrically connected with the external terminal and the transfer terminal, and the transfer circuit is coiled and/or meandered between the external terminal and the transfer terminal. In an embodiment, the battery pack may further include a bent pipe member, the bent pipe member may be sleeved outside the switching circuit, and a cross-sectional area of an end of the bent pipe member near the external terminal is larger than a cross-sectional area of an end near the switching terminal. Therefore, when the switching terminal moves relative to the external terminal, the bending pipe member is relatively thicker at the external terminal side, so bending deformation is less likely to occur, but bending deformation is likely to occur because the switching terminal is relatively thinner.
Therefore, the moving amplitude of the side, which is closer to the external terminal, of the switching circuit is smaller, the moving quantity of the circuit is relatively small, and the problem that the electrical insulation performance of the battery pack is reduced due to the fact that the external terminal and the switching circuit are invalid after being subjected to multiple large-scale movements is avoided.
According to the battery pack provided by the embodiment of the application, the external terminal, the switching circuit and the bent pipe member are arranged in the space defined by the first wall part, the second wall part and the side part, so that the external terminal, the switching circuit and the bent pipe member form a shielding effect, and the electrical insulation performance of the battery pack is enhanced.
According to the battery pack provided by the embodiment of the application, the compensation assembly can further comprise a first compensation member and a second compensation member. In an embodiment, the first compensation member is connected to the compensation mounting portion, the second compensation member is connected to the compensation support portion, and the second compensation member is movably connected to the first compensation member such that the compensation support portion can be moved closer to the tank and further from the tank.
In an embodiment, one of the first compensation member and the second compensation member is sleeved outside the other of the first compensation member and the second compensation member. Thereby, even at the limit position where the compensation support portion can be away from the case between the first compensation member and the second compensation member, the stability of the connection of both the first compensation member and the second compensation member can be ensured due to the existence of the nesting relationship.
According to the battery pack provided by the embodiment of the application, the first compensation member and the second compensation member are in threaded connection, the compensation assembly can further comprise a telescopic support member, the telescopic support member is provided with two opposite ends, one of the two ends of the telescopic support member is connected with the first one of the first compensation member and the second compensation member, the other one of the two ends of the telescopic support member is abutted with the second one of the first compensation member and the second compensation member, and the telescopic support member has a stretching trend. In an embodiment, the telescopic support member provides a pre-tightening force for the first and second compensation members at all times, thereby avoiding wobble of the first compensation member relative to the second compensation member.
