The battery cell comprises an electrode assembly and electrolyte, wherein the electrode assembly consists of a positive plate, a negative plate and a separation membrane. The battery cell mainly relies on metal ions to move between the positive and negative electrode plates to operate. The positive plate comprises a positive electrode current collector and a positive electrode active material layer, wherein the positive electrode active material layer is coated on the surface of the positive electrode current collector, the positive electrode current collector without the positive electrode active material layer protrudes out of the positive electrode current collector coated with the positive electrode active material layer, and the positive electrode current collector without the positive electrode active material layer is used as a positive electrode lug.

The reason why the output electrode base and the output electrode of the battery module cannot accurately correspond is as follows: on the one hand, the output electrode base and the end plate have an assembling error which cannot be eliminated, so that the output electrode base and the output electrode of the battery module cannot be accurately corresponding; on the other hand, there is an error in the position of the output electrode itself.

Generally, the output electrode is connected to the output electrode base through a bolt, and if the output electrode base and the output electrode of the battery module cannot accurately correspond, two problems will result: on the one hand, the output electrode base and the output electrode are difficult to insert to connect, so that the output electrode base and the output electrode are difficult to connect and assemble; on the other hand, if the output pole mount is directly connected to the bar (e.g., copper bar). The tab passes through bolted connection with the output pole base, and under the unable accurate condition that corresponds of hookup location and output pole base of tab, use the bolt to be connected output pole base and output pole (example tab), easily lead to the tab to warp, be connected unstably between output pole base and the output pole, and then fracture leads to the output pole to be invalid with the connection between the output pole base.

In some embodiments, referring to fig. 4 and 5, fig. 4 is a schematic structural diagram of an end plate assembly 1 according to some embodiments of the present application; fig. 5 is an exploded view of an end plate assembly 1 provided in some embodiments of the present application. The end plate assembly 1 includes an end plate 12, an output pole mount 13, and an adjustment mechanism 14. The output electrode mount 13 is provided on the end plate 12. The adjusting mechanism 14 connects the output pole base 13 and the end plate 12, and the adjusting mechanism 14 is used for adjusting the position of the output pole base 13 on the end plate 12 along a first direction intersecting the width direction X of the end plate 12.

The first direction is the direction in which the output pole needs to be adjusted in position.

By providing the adjusting mechanism 14, the position adjustment of the output electrode base 13 in the first direction is facilitated, so that the output electrode base 13 corresponds to the connection position of the output electrode (not shown in the figure) of the battery module 10, and the output electrode base 13 is facilitated to be correspondingly connected with the output electrode.

The battery modules 10 with different specifications and different use scenes have different installation requirements on the output electrode base 13, so that the directions of the output electrode base 13 to be adjusted are different. Thus, in other embodiments, the first direction may be a direction that is at an angle to the thickness direction Z of the end plate 12; the first direction may also be a direction that is at an angle to the height direction Y of the end plate 12.

On the other hand, when the plurality of battery cells 11 are placed at different positions, the output electrode base 13 does not correspond to the output electrode in the thickness direction Z of the end plate 12. On the other hand, the output electrode mount 13 does not correspond to the output electrode in the thickness direction Z of the end plate 12 due to harness isolation or positional deviation of the tabs themselves. Therefore, for the output pole mount 13, more consideration is given to the positional adjustment of the output pole mount 13 over the thickness of the end plate 12.

In some embodiments, referring to fig. 6, the first adjusting member 141 penetrates through the output pole base 13 and is fixedly connected with the end plate 12, so as to limit the second adjusting member 142 between the first adjusting member 141 and the output pole base 13, one end of the second adjusting member 142 abuts against the first adjusting member 141, and the other end is connected with the output pole base 13.

Wherein, both ends of the second adjustment member 142 may be both ends in the first direction.

The first adjusting member 141 penetrates through the output electrode base 13 and is fixedly connected with the end plate 12, and the fixed connection refers to the connection that the first adjusting member 141 and the end plate 12 do not generate relative movement after the first adjusting member 141 and the end plate 12 are fixedly connected.

Since the output pole base 13 is connected to the second adjusting member 142, when the second adjusting member 142 moves relative to the first adjusting member 141, the output pole base 13 also moves relative to the first adjusting member 141.

The second regulating member 142 is constrained between the first regulating member 141 and the output pole base 13 to convert the relative movement of the second regulating member 142 and the first regulating member 141 into the relative movement between the output pole base 13 and the first regulating member 141, thereby adjusting the position of the output pole base 13 in the first direction.

In some embodiments, referring to fig. 6, the first adjusting member 141 includes an abutting portion 1411 and a connecting portion 1412, wherein the width of the abutting portion 1411 is larger than the width of the connecting portion 1412, the abutting portion 1411 is disposed on the first side 131 of the output pole base 13, and the connecting portion 1412 extends from the first side 131 of the output pole base 13 to the second side 132 of the output pole base 13 to connect with the end plate 12.

The first side 131 and the second side 132 may be opposite sides of the output pole mount 13 in the first direction.

The abutment 1411 abuts the second adjuster 142 to restrain the second adjuster 142 between the abutment 1411 and the end plate 12.

The abutment 1411 may be provided at one end of the connection 1412.

In some embodiments, the abutment 1411 may also be provided in the middle of the connection.

The abutment 1411 of the first adjuster 141 may be circular, polygonal, rectangular, etc., which is not limited in this application.

The width of the abutting portion 1411 is greater than the width of the connecting portion 1412, so that the second adjusting member 142 abuts against the abutting portion 1411 to limit the second adjusting member 142 between the output pole base 13 and the first adjusting member 141, and the connecting portion 1412 penetrates from the first side 131 of the output pole base 13 to the second side 132 of the output pole base 13 to be connected with the end plate 12.

In some embodiments, the second adjusting member 142 is disposed in a tubular shape, and the second adjusting member 142 is sleeved on the connecting portion 1412 and abuts against the abutting portion 1411.

The second adjusting member 142 is sleeved on the connecting portion 1412, and the second adjusting member 142 can rotate or slide relative to the first adjusting member 141, so that the second adjusting member 142 moves relative to the first adjusting member 141, and the position of the output electrode base 13 on the end plate 12 is adjusted.

In some embodiments, referring to fig. 6, the second adjusting member 142 is screwed with the output pole base 13.

Specifically, in the process of adjusting the second adjusting member 142, the second adjusting member 142 is abutted against the first adjusting member 141, so that the second adjusting member 142 cannot move along the first direction, and the second adjusting member 142 is in threaded connection with the output electrode base 13, at this time, the output electrode base 13 moves along the first direction relative to the second adjusting member 142, and the position of the output electrode base 13 on the end plate 12 is adjusted.

The existing output pole base 13 is usually clamped to the end plate 12, and a gap exists between the output pole base 13 and the end plate 12 due to the clearance at the clamped position, so that the output pole base 13 has activity in the first direction.

If the output electrode base 13 has a movable amount in the first direction, the output electrode base 13 is in a semi-free state, which has a number of drawbacks. For example, after the output pole base 13 is adjusted to a position corresponding to the output pole, the output pole base 13 moves in the first direction again when there is activity in the first direction, and the position of the output pole base 13 needs to be readjusted, which affects the installation efficiency.

For another example, taking a bolt to connect the output electrode with the output electrode base 13 as an example, after connection is completed, the output electrode base 13 has activity along the first direction, and in the use process of the battery module 10, the output electrode base 13 moves along the first direction, the output electrode follows the output electrode base 13 to move along the first direction, and the output electrode and the bolt are continuously extruded to generate interaction force, so that the output electrode (such as copper bar) is easily deformed or even broken. Therefore, the gap can be eliminated through the threaded connection between the second adjusting piece 142 and the output electrode base 13, so that the structure is more stable, and the possibility that the output electrode is damaged due to continuous interaction between the output electrode and the bolt in the use process is reduced.

The second adjusting piece 142 is in threaded connection with the output pole base 13, so that the position of the output pole base 13 can be accurately adjusted along the first direction, after the adjustment is completed, the output pole base 13 does not have activity, the position of the output pole base 13 relative to the end plate 12 is fixed, and the defect caused by the activity of the output pole base 13 along the first direction is overcome.

In some embodiments, the first adjustment member 141 is threadably coupled to the end plate 12. The connecting structure is simple, the first adjusting piece 141 and the end plate 12 are convenient to detach and connect, and the output electrode base 13 is convenient to detach and install.

In other embodiments, the first adjusting member 141 and the end plate 12 may be welded, adhered, snapped, or otherwise connected.

In some embodiments, referring to fig. 5 and fig. 7, fig. 7 is a schematic structural diagram of a second adjusting member 142 according to some embodiments of the present application. The first adjusting member 141 is a bolt, and the second adjusting member 142 is a pin bush.

Specifically, the bolt includes a head portion and a shaft portion, the abutment portion 1411 is the head portion of the bolt, the connection portion 1412 is the shaft portion of the bolt, the width of the head portion is greater than the shaft portion of the bolt, the head portion of the bolt is used for abutting the second adjusting piece 142, the head portion is disposed on the first side 131 of the output pole base 13, and the shaft portion penetrates from the first side 131 of the output pole base 13 to the second side 132 of the output pole base 13.

Of course, an abutment 1411 (not shown) may be provided in the shank of the bolt, and the abutment 1411 may be the same or different in shape from the head of the bolt (e.g., the head of the bolt is deformed more than once, and the abutment 1411 is circular in shape).

Further, the shank of the bolt is connected to the end plate 12, the pin bush is fitted to the shank of the bolt, one end of the pin bush abuts against the head of the bolt, and the outer peripheral surface of the pin bush is screwed to the output electrode base 13. By rotating the pin sleeve relative to the bolt, the output pole base 13 can be moved in a first direction relative to the pin sleeve, thereby enabling adjustment of the position of the output pole base 13 on the end plate 12 in the first direction.

In some embodiments, adjustment may be achieved by manually rotating the pin sleeve.

In some embodiments, the pin sleeve may also be driven to rotate by a driver.

Further, referring to fig. 7, a third positioning portion 1421 may be provided on the second adjusting member 142 (e.g. a pin sleeve), and at this time, the second adjusting member 142 may be turned by a structural tool (e.g. a sleeve, not shown) corresponding to the third positioning portion 1421, so as to facilitate manual operation.

In some embodiments, referring to fig. 4 and 6, the second adjusting member is exposed on a side surface of the output electrode base 13 perpendicular to the thickness direction Z of the end plate 12.

As shown in fig. 5, the second adjusting member 142 has a rectangular structure, a side surface of the output electrode base 13 perpendicular to the thickness direction Z of the end plate 12 is a first side 131, and the second adjusting member 142 is exposed from the first side 131. The second adjusting member 142 extends beyond the first side 131, so that the second adjusting member 142 is adjusted by a portion of the second adjusting member 142 exposed at the first side 131, such that the second adjusting member 142 moves relative to the first adjusting member 141, thereby adjusting the position of the output electrode base 13 on the end plate 12 along the first direction.

In some embodiments, the side of the output pole mount 13 perpendicular to the thickness direction Z of the end plate 12 may be the first side 131 of the output pole mount 13.

In some embodiments, the output pole mount 13 is provided with a mounting groove 133, the mounting groove 133 being exposed to a side surface of the output pole mount 13 parallel to the thickness direction Z of the end plate 12.

The mounting groove 133 is a groove-like structure of the output electrode mount 13 for connecting the output electrodes. Bolts may be inserted into the output pole mount 13 and the mounting groove 133 to connect the output pole with the output pole mount 13, but are not limited thereto.

When the adjustment mechanism 14 adjusts the position of the output electrode base 13 in the thickness direction Z of the end plate 12, since the mounting groove 133 is provided at the output electrode base 13, the position of the mounting groove 133 in the thickness of the end plate 12 is also adjusted so as to correspond to the output electrode to which the battery module 10 is connected.

In some embodiments, the output electrode base 13 is provided with a first positioning portion 13a, and the end plate 12 is provided with a second positioning portion 12b, where the first positioning portion 13a is used for being matched and positioned with the second positioning portion 12 b.

The first positioning portion 13a and the second positioning portion 12b are positioned in cooperation to function as a predetermined positioning. The benefit of the pre-positioning is that before the adjusting mechanism 14 adjusts, the output pole base 13 can be pre-corresponding to the output pole through the cooperation of the first positioning part 13a and the second positioning part 12b, so that the installation efficiency of the output pole base 13 is improved.

It should be noted that, the first positioning portion 13a and the second positioning portion 12b are made of non-rigid materials, and the first positioning portion 13a and the second positioning portion 12b may still slightly deform under the action of external force, so when the first positioning portion 13a and the second positioning portion 12b are pre-positioned, it is found that the output pole base 13 and the output pole are not accurately corresponding, at this time, the adjusting mechanism 14 may still adjust the position of the output pole base 13 along the first direction, and after the adjustment is completed, the first positioning portion 13a and the second positioning portion 12b may be in a non-corresponding state.

In some embodiments, the first positioning portion is a protrusion and the second positioning portion 12b is a groove corresponding to the protrusion.

In this embodiment, the first positioning portion 13a may be made of rubber, silicone, or the like.

In other embodiments, the first positioning portion 13a may be a groove, and the second positioning portion 12b may be a protrusion.

In some embodiments, the protrusions and recesses are provided as an interference fit. The interference fit has the advantage of good centering, and the output electrode base 13 is not easy to move after being installed.

In some embodiments, the interference is 0.1mm to 0.5mm when the protrusion is received in the recess.

Alternatively, the interference may be 0.1mm, 0.2mm, 0.3mm, 0.4mm, 0.5mm, etc.

If the interference is less than 0.1mm, the first positioning portion 13a and the second positioning portion 12b cannot be tightly matched, and the output electrode base 13 may still move after being mounted, so as to affect the connection effect of the output electrode base 13 and the output electrode of the battery module 10.

If the interference is greater than 0.5mm, after the output electrode base 13 is tightly matched with the second positioning portion 12b through the first positioning portion 13a, if the mounting groove 133 on the output electrode base 13 does not correspond to the output electrode of the battery module 10, it becomes difficult or impossible to adjust the position of the output electrode base 13 along the first direction.

Therefore, the interference is between 0.1mm and 0.5mm, so that the possibility that the output pole base 13 moves after the first positioning part 13a and the second positioning part 12b are matched and positioned can be reduced, and the position of the output pole base 13 is adjusted along the first direction by the adjusting mechanism 14.

In other embodiments, the width of the positioning groove may be larger than the width of the positioning protrusion. At this time, a gap exists between the positioning groove and the positioning protrusion, and the activity amount exists in the output electrode base 13, so that the position of the output electrode base 13 can be conveniently adjusted along the first direction through the adjusting mechanism 14, and meanwhile, the output electrode base 13 is accurately positioned.

In some embodiments, referring to fig. 8 and 9, fig. 8 is a schematic structural diagram of a third adjusting member 143 connected to the output pole base 13 according to some embodiments of the present disclosure; fig. 9 is a partial schematic view of an adjustment mechanism 14 including a third adjustment member 143 provided in some embodiments of the present application. The adjusting mechanism 14 includes a third adjusting member 143, the third adjusting member 143 being fixed relative to the output pole base 13 in the first direction and being rotatable relative to the output pole base 13, the third adjusting member 143 being threadedly coupled to the end plate 12.

The fact that the third adjusting member 143 is fixed relative to the output pole base 13 in the first direction means that the third adjusting member 143 and the output pole base 13 do not move relative to each other in the first direction. However, the third regulating member 143 and the output pole base 13 are relatively movable in other directions, for example, the sixth regulating member 147 is rotatable with respect to the output pole base 13 about an axis P parallel to the thickness direction Z of the end plate 12.

The third adjustment member 143 may be provided with a flange 1431 that limits movement of the output pole mount 13 in the first direction to achieve a fixation of the third adjustment member 143 relative to the output pole mount 13 in the first direction.

In this embodiment, the third adjusting member 143 is screwed to the end plate 12, and during the screwing or screwing process of the third adjusting member 143, the third adjusting member 143 moves along the first direction, and the output electrode base 13 moves along with the third adjusting member 143, so as to adjust the position of the output electrode base 13 on the end plate 12 along the first direction. And the precision of adjusting through the screw thread is higher.

After the adjustment is completed, the third adjusting member 143 is fixed relative to the end plate 12 along the first direction, so that the output electrode base 13 is fixed relative to the end plate 12, and the output electrode base 13 has no activity, thereby overcoming the defect caused by the activity of the output electrode base 13 along the first direction.

In some embodiments, referring to fig. 10, fig. 10 is a partial schematic view of an adjusting mechanism 14 according to some embodiments of the present application, including a fourth adjusting member 144 and an elastic member 145.

The fourth adjusting member 144 is screwed with the end plate 12, so that the position of the output electrode base 13 in the first direction can be adjusted steplessly.

The elastic member 145 can deform after being stressed and has a tendency to recover, and the elastic member 145 is used for abutting against the output electrode base 13. The elastic member 145 may be a spring or a rubber pad, etc.

The fourth adjuster 144 may be a bolt.

In this embodiment, the fourth adjusting member 144 penetrates through the output electrode base 13 and is in threaded connection with the end plate 12, and in the process of screwing in the fourth adjusting member 144, the elastic member 145 deforms and compresses along the first direction, and the elastic member 145 is always abutted between the output electrode base 13 and the end plate 12, so that the output electrode base 13 moves along the direction (i.e. the first direction) in which the elastic member 145 is compressed; in the process of unscrewing the fourth adjusting member 144, the elastic member 145 has a restoring trend along the first direction, and the elastic member 145 is always abutted between the output pole base 13 and the end plate 12, so that the output pole base 13 moves along the restoring direction (i.e. the first direction) of the elastic member 145.

When the fourth adjusting member 144 is used to adjust the output pole base 13 to accurately correspond to the output pole, the fourth adjusting member 144 stops screwing in or screwing out, at this time, the positions of the fourth adjusting member 144 and the end plate 12 in the first direction are relatively fixed, the output pole base 13 is abutted between the elastic member 145 and the first adjusting member 141, no activity exists in the output pole base 13 along the first direction, and after the fourth adjusting member 144 adjusts the output pole base 13 to accurately correspond to the output pole, the output pole base 13 cannot move due to the activity, so that the installation efficiency is improved.

The fifth adjusting member 146 is fixedly connected to the end plate 12, and may be welded or integrally formed.

The sixth adjustment member 147 being fixed relative to the output pole mount 13 in the first direction means that no relative movement of the sixth adjustment member 147 and the output pole mount 13 occurs in the first direction. However, the sixth adjustment member 147 and the output pole base 13 are relatively movable in other directions, for example, the sixth adjustment member 147 is rotatable with respect to the output pole base 13 about an axis P parallel to the thickness direction Z of the end plate 12.

The sixth adjusting member 147 may be a tubular structure and the sixth adjusting member 147 may be provided with internal threads by which it is threadedly coupled to the fifth adjusting member 146.

The sixth adjusting member 147 is fixed relative to the output pole base 13 in the first direction, that is, the sixth adjusting member 147 and the output pole base 13 do not move relative to each other in the first direction, and if the sixth adjusting member 147 is moved in the first direction, the output pole base 13 moves along the first direction synchronously with the sixth adjusting member 147, so that the position of the output pole base 13 on the end plate 12 is adjusted in the first direction.

In addition, the sixth adjusting member 147 is in threaded connection with the fifth adjusting member 146, so that the position of the output electrode base 13 can be accurately adjusted along the first direction, after the adjustment is completed, the sixth adjusting member 147 is fixed relative to the position of the end plate 12 along the first direction, and then the output electrode base 13 is fixed relative to the position of the end plate 12, so that the activity of the output electrode base 13 is reduced, the connection stability of the output electrode base 13 and the end plate 12 is improved, and the use reliability of the end plate assembly 1 is improved.

In this embodiment, since the fifth adjusting member 146 is fixedly connected to the end plate 12, the position of the fifth adjusting member 146 relative to the end plate 12 in the first direction is fixed, the sixth adjusting member 147 is screwed to the fifth adjusting member 146, the sixth adjusting member 147 is rotated, the sixth adjusting member 147 moves relative to the fifth adjusting member 146 in the first direction, the output electrode base 13 moves along the first direction following the sixth adjusting member 147, and the position of the output electrode base 13 in the first direction is adjusted.

In some embodiments, the sixth adjustment member 147 may also be provided with a flange 1431 that limits movement of the output pole mount 13 in the first direction to achieve a fixation of the sixth adjustment member 147 relative to the output pole mount 13 in the first direction.

In some embodiments, the end plate 12 is provided with a receiving groove 122, the receiving groove 122 penetrates one side of the end plate 12 along the thickness direction Z of the end plate 12, and the output electrode base 13 is received in the receiving groove 122.

The shape of the receiving groove 122 corresponds to the shape of the output pole mount 13, and illustratively, in the drawing, the output pole mount 13 is rectangular, and the receiving groove 122 is also rectangular.

Optionally, the accommodating groove 122 is located at a side of the end plate 12 facing away from the battery cell 11.
