Description

Battery cell and method for connecting battery cells
Technical Field
The invention proceeds from a battery cell or a method according to the generic type of the independent claims. The subject of the invention is also a battery pack, a battery module, a battery pack and a vehicle.
Background
DE 102013201021 Al discloses a battery module having a plurality of battery cells and a plurality of containers for accommodating the battery cells. Each container of the battery module has a container bottom, a container cover and a container wall arranged between the container bottom and the container cover and formed from plastic. In addition, each container bottom has a cooling plate integrated thereon, such that a thermally conductive contact can be established between the battery cells arranged in the respective container and the cooling plate.
DE 102011089949 Al discloses a battery module comprising a plurality of battery cells which are interconnected to form a desired module structure, wherein each battery cell has a separate metal housing. The battery module according to the invention is characterized in that substantially the entire battery module is closed with a shrink tube that is sealed against air to prevent the surrounding environment.
DE 102011088595 Al discloses a battery module comprising a plurality of battery cells which are joined to form a battery pack, which are each accommodated in a metal housing with an electrically insulating coating and two adapter plates which bear laterally against the outer battery cells of the battery pack. The battery module is characterized in that a half formed of an electrically insulating material is arranged between the adapter plate and the outer battery cells, said half covering at least the annular side of the outer battery cells directed towards the adapter plate.
Disclosure of Invention
The battery cell and the method having the features of the independent claims have the advantage that the electrical connection of the battery cell can be simplified. Thereby the length of the electrical connection may be shortened and/or the number of components along the electrical connection may be reduced. This can reduce power losses and/or, for example, increase the radius of action of the vehicle. Furthermore, the weight and/or volume of the battery pack, battery module and/or battery pack may be reduced. Furthermore, the structural height of the battery pack, battery module and/or battery pack can be reduced. Battery cells, such as battery cells for battery-powered electric vehicles (BEV) or plug-in hybrid electric vehicles (PHEV), battery packs, battery modules and/or battery packs may thus be used for installation in the vehicle underbody (underbody installation), for example. The vehicle can thus be given a flatter type or form of construction and/or the vehicle centre of gravity can be lowered. Thus, safety can be improved. Furthermore, the front (front) of the battery cell, i.e. the larger side, can be made readily available. Thereby increasing the contact surface to the temperature adjustment element. The temperature regulation, i.e. cooling or heating, of the battery cells, the battery pack, the battery module and/or the battery pack may thus be improved. In addition, the number of working steps, for example, connecting steps, in manufacturing the battery pack, the battery module, and/or the battery pack can be reduced. Costs, such as manufacturing costs and operating costs, can thus be reduced.
Advantageous developments and improvements of the device and the method with the features of the independent claims can be achieved by the measures mentioned in the dependent claims.
If the first terminal comprises a first free end for contacting a terminal of a further battery cell, this has the advantage that the electrical connection can be implemented more flexibly. If the additional battery cells are structurally identical, adapted or compatibly constructed with the battery cells, this furthermore has the advantage that the battery cells can be connected to one another as required. The matched or compatible battery cell can have, for example, half the capacity and therefore half the size, or twice the capacity and therefore twice the size, relative to the battery cell.
If the second terminal comprises a second free end for contacting a terminal of a further battery cell, this has the advantage that the electrical connection can be implemented more flexibly.
If the first and second terminals are identically or substantially identically constructed, embodied or shaped, this has the advantage that the manufacture of the battery cell can be simplified. Here, the number of different components can be reduced. Therefore, costs such as manufacturing costs and storage and keeping costs can be reduced.
If the back face of the first terminal and the front face of the second terminal are aligned with each other, this has the advantage that the terminals of the battery cells can be directly connected to each other, for example, bonded, clamped, screwed or welded. The battery connector can be eliminated.
If the battery cells are constructed as prismatic battery cells, this has the advantage that the battery cells can be arranged approximately seamlessly from one another in a space-saving manner.
If the first and second terminals are arranged on the battery cell cover plate, this has the advantage that the battery cell can be configured, for example, with regard to the size and position of the terminals by applying different battery cell cover plates.
If the battery cells are fixed, glued, stuck, screwed, clamped or engaged in the battery housing cover, this has the advantage that the battery cells are prevented from falling out or slipping out of the battery housing cover.
If the cooling plate is placed on the battery cells, this has the advantage that the battery cells and, if necessary, other battery cells can be cooled. The effective power and life span of the battery module can be improved.
If the battery pack comprises a further pack housing cover, this has the advantage that the battery pack can be constructed modularly and/or symmetrically. The structure of the battery pack can thereby be simplified.
If a further plurality of battery cells is arranged in a further battery housing cover such that the first terminal of one of the further battery cells and the second terminal of another of the further battery cells face each other and the further battery cells are arranged offset or shifted from each other, this has the advantage that the battery module may comprise further cell planes. For example, cooling plates can thereby be arranged between the cell planes. The structure of the battery pack can be further simplified.
This has the advantage that the structure of the battery pack can be simplified again if the terminals of the further battery cells are connected to other battery strings.
If the additional battery cells are fixed, glued, stuck, screwed, clamped or engaged in the additional battery housing cover, this has the advantage that the additional battery cells can be prevented from falling out or slipping out of the additional battery housing cover.
If a further battery housing cover is placed on top of the battery housing cover, this has the advantage that the battery cells can be closed and protected like a box. In a corresponding design, the battery housing cover and the further battery housing cover may have the same battery housing cover shape.
If the first terminal of the last battery cell of the battery string and the second terminal of the first battery cell of the further battery string are connected by means of a battery connector or a wire for connecting the battery string and the further battery string into an overall string, this has the advantage that the battery pack can provide a higher terminal voltage.
This has the advantage that the battery cells can be better protected if the battery housing cover is closed.
If devices such as battery pack control devices, battery pack separating devices, battery cell monitoring circuits or temperature regulating devices are placed or built into the battery pack housing cover and/or into further battery pack housing covers, this has the advantage that the functionality of the battery pack can be increased.
This has the advantage that the monitoring of the battery cells can be improved if sensors, such as temperature sensors, voltage measuring sensors or current measuring sensors, are inserted and connected. Whereby the reliability and life of the battery pack can be improved.
This has the advantage that the battery cells, the device and the sensor can be connected to one another more reliably if a cable harness is applied. Space requirements can be reduced by laying a cable harness in the terminal-side space between the battery cells. The battery pack can thereby be constructed more compactly.
The vehicle may be configured as, for example, a motor vehicle such as an Electric automobile, a hybrid vehicle, a plug-in hybrid vehicle, an Electric motorcycle (Electric-Bike, E-Bike) or an Electric bicycle (Pedal Electric Cycle), a marine vessel such as an Electric boat or a submarine (U-Boot), an airplane, or a spacecraft.

Detailed Description
Fig. 1 shows a simplified front view of a battery cell 10 according to an embodiment of the present invention.
The battery cell 10 may be configured as a prismatic battery cell as exemplarily shown in fig. 1. The battery cell 10 comprises a battery cell housing 12, a battery cell cover 13, and a first terminal (cell terminal) 14, which can be designed as a negative electrode as shown in fig. 1 by way of example, and a second terminal 18, which can be designed as a positive electrode as shown in fig. 1 by way of example, which are arranged on the battery cell cover 13. The first terminal 14 comprises a first free end 15, which, as exemplarily shown in fig. 1, may be configured in the direction of the second terminal 18. The second terminal 18 comprises a second free end 19, which, as exemplarily shown in fig. 1, may be configured in the direction of the first terminal 14. The first terminal 14 and the second terminal 18 may be identically configured. As exemplarily shown in fig. 1 for first terminal 14, first terminal 14 and/or second terminal 18 may include a slope 16 or a step (Phase). The chamfer may be used for marking of the respective terminal 14, 18. Thus, the first terminal 14 and the second terminal 18 may be substantially identically configured. The first terminal 14 and/or the second terminal 18 may include a metal such as aluminum, copper, or steel.
Fig. 2 shows a simplified top view of the battery cell 10 according to this embodiment of the invention.
The pack lid 13 forms a rectangular face whose long sides are defined by the front faces of the battery cells 10 and whose short sides are defined by the side faces of the battery cells 10. A center line runs centrally on the battery cover 13 parallel to the front side. The first terminal 14 is configured on this face along the midline. Therefore, the first terminals 14 are symmetrically arranged on the center line, and the front surface (lower side in fig. 2) and the rear surface (upper side in fig. 2) of the first terminals 14 extend parallel to the center line at substantially the same distance. The second terminal 18 is spaced from the center line on the face without overlapping the first terminal 14. Thus, the second terminals 18 are arranged asymmetrically with respect to the central line, and the front and rear faces of the second terminals 18 extend parallel to the central line over half of the face. Here, as exemplarily shown in fig. 2, the back surface of the first terminal 14 and the front surface of the second terminal may be aligned or substantially aligned with each other. The first terminal 14 and the second terminal may be spaced apart from the closest side by equal widths as exemplarily shown in fig. 2.
Figure 3 shows a simplified front view of a battery pack 100 according to another embodiment of the invention.

Here, the battery cell 101, 102Are arranged to be staggered or shifted by half of the long sides from each other such that the first battery cell 101First terminal (negative electrode) 141And a second battery cell 102Second terminal (positive electrode) 182Face each other. Thus the battery cell 101, 102May be electrically connected in series with each other.
Fig. 4 shows a simplified side partial cross-sectional view of the battery pack 100 according to the another embodiment of the present invention.
Fig. 4 shows the first battery cell 10 with reference to fig. 31And the second battery cell 102Corresponding cross section of (a).
