Furthermore, the structural unit has an interface unit configured to form a connection with a module element, wherein a second function of the battery management system can be performed on the structural unit and / or the module element by means of the connection.

[0012] The subclaims show preferred developments of the invention.

[0013] Preferably, the interface unit is configured to form the connection by means of a force and / or form fit.

[0014] An advantage of this embodiment is that the structural unit can be used in a variety of battery management systems, since additional module elements can be coupled to the structural unit by means of the force-fitting and / or form-fitting connection, thus being able to respond, for example, to an adjusted number of rows or an adjusted voltage of the battery management system. Furthermore, the force-fitting and / or form-fitting connection between the structural unit and the module element can further reduce manufacturing costs, since they can be easily plugged into one another, particularly by means of a special outer contour, thus forming a contact or connection.

[0015] Further preferably, the interface unit is configured to form a plurality of connections with a plurality of module elements.

[0016] An advantage of this design is that the module elements can be highly specialized in their function, thus further reducing the manufacturing costs for the module elements. For example, by combining multiple module elements, the preferred voltage on the structural unit can be specifically adjusted, since each module element has a predetermined voltage value, and by connecting the respective module elements in series or parallel, these can be combined in a targeted manner.

[0017] Preferably, the interface unit comprises a first connecting element and a second connecting element, wherein a first module element can be arranged on the first connecting element in order to form a first connection, wherein a second module element can be arranged on the second connecting element in order to form a second connection.

For example, the first module element can have a logic unit configured to control the second module element and / or the structural unit. In this case, the second module element can, in particular, be a switch arrangement for controlling the charging and discharging of a battery unit. In the event that one of these elements is defective, only the element identified as defective can be replaced, thus significantly reducing maintenance costs.

[0023] Further preferably, the interface unit is configured to at least partially transmit the energy of the second functional element to the module element.

[0025] An advantage of this embodiment is that the required number of components of the structural unit can be further reduced, since the number of components on the structural unit can remain essentially the same, particularly despite increasing functionality. For example, the third functional element can be a CAND receiver with a bus wake-up function.

The fifth functional element can, in particular, be a wake-up logic and a hold logic. More preferably, the sixth functional element can be an LED current driver.

[0026] Preferably, the functional unit and the interface unit and / or the first functional element and the second functional element and / or the third functional element and the fourth functional element and the fifth functional element and the sixth functional element are arranged on a single platinum element.

[0027] An advantage of this embodiment is that the required installation space of the structural unit can be further reduced. Thus, the structural unit can be used in a variety of battery management systems, as it is not only adaptable to a battery unit but can also be fitted into various housings using the interface unit. The individual platinum element is in particular a PCB or similar, on which the functional units can be arranged, for example, using a soldered connection or the like.

Further preferably, the modular element can also connect a first structural unit to a second structural unit. Furthermore, the modular element can also comprise a plurality of interface units.

[0033] Preferably, the module element is configured to transmit a signal and / or energy provided by the second module element to the first structural unit and / or the second structural unit by means of the interface unit.

[0034] An advantage of this embodiment is that the module element can serve as a connecting element between the second module element and the structural unit, in order to be able to exchange both signals and energy between the structural unit and the second module element by means of the module element.

[0035] Further preferably, the module element has at least one switch arrangement which is configured to control a battery unit.

[0036] An advantage of this embodiment is that the module element can be arranged multiple times on a structural unit in order to provide multiple switch requirements for controlling multiple battery units. For example, the switch arrangement is a power MOSFET, in particular a charge and discharge FET.

[0037] Preferably, the module element has a current detection element.

[0038] An advantage of this embodiment is that the voltage and / or current of a battery unit can be monitored by means of the current detection element. Preferably, the module element has a logic unit, wherein the logic unit is configured to control at least one function of the first structural unit and / or the second module element by means of the interface unit.

[0039] An advantage of this embodiment is that, if the logic unit is defective, it can be easily replaced without having to replace the structural unit and other module elements. For example, the logic unit can be a controller or microcontroller. More preferably, the module element with the logic unit can be designed as an application-specific integrated circuit. In this case, the logic unit can control or monitor a function of the structural unit and / or of the module element or of the second module element, in particular by means of the interface unit. In this case, for example, the logic unit of the module element can access and control a functional element of the structural unit. More preferably, the logic unit of the module element can access or control, in particular, a switch arrangement of a further module element and / or a current detection element of a further module element.

[0040] Further preferably, the module element can be connected to a plurality of module elements.

For example, the plurality of module elements can be arranged along a chain. More preferably, the plurality of module elements can be arranged in a serpentine or other form, thus allowing adaptation to the available installation space.

[0042] Preferably, a first module element of the plurality of module elements comprises the logic unit, wherein the logic unit is configured to control all further module elements of the plurality of module elements and / or the structural unit.

[0043] An advantage of this embodiment is that only one logic unit is required to control both a plurality of module elements and the structural unit. Thus, the number of components of the battery management system can be further reduced, as can costs. Preferably, the module element has an outer contour configured to form a positive and / or non-positive connection with at least one further module element to form at least part of the interface unit.

[0044] An advantage of this embodiment is that a large number of module elements can be connected to one another by means of a force-fitting and / or form-fitting connection.

More preferably, the outer contour can be adapted such that a large number of module elements can each be connected to one another in only one orientation, thus preventing the possible incorrect assembly of two module elements. For example, the outer contour can be designed using the Poka Yoke principle in order to be able to connect a large number of module elements to one another without errors.

[0045] A further aspect of the invention relates to a vehicle having a module element as described above and below.

Furthermore, the first conduction path is arranged in a predetermined orientation relative to the second conduction path, wherein the first conduction path and the second conduction path are connected in a signal- and / or energy-conducting manner. By means of the predetermined orientation, the first conduction path is configured to provide a first signal and / or energy to a first outer side and a second outer side of the module element.

[0047] An advantage of this embodiment is that, thanks to a standardized signal traverse, a plurality of module elements can be freely combined with one another based on the predetermined orientation. Further preferably, the predetermined orientation is configured to arrange the first conduction path and the second conduction path substantially orthogonal to one another.

[0048] An advantage of this embodiment is that, in an orthogonal arrangement, all four sides of a square or rectangular module element typically have at least part of the conduction path. In this context, "substantially orthogonal" can mean that an angle of ±45° between the first conduction path and the second conduction path is included, particularly taking into account manufacturing tolerances.

[0052] Further preferably, the module element is configured to form a connection with a further module element by means of an interface unit, wherein the first conduction path can be connected to a further first conduction path of the further module element by means of the connection.

[0053] An advantage of this embodiment is that when two module elements are connected by means of a force-fitting and / or form-fitting connection, the connection automatically also connects the first conduction path to the further first conduction path, so that no incorrect contact or the like can occur. In other words, a signal and / or energy transported via the first conduction path can be transmitted from the first conduction path to a further conduction path of the further module element via the connection of the interface unit to a further module element. Thus, for example, a signal and / or energy can be transmitted from the further module element to a structural unit via the module element, or vice versa.

[0054] Further preferably, the module element can be connected to a plurality of module elements by means of the interface unit, wherein the plurality of module elements and the module element have the predetermined orientation in order to connect the plurality of functional modules in a signal- and / or energy-conducting manner.

[0055] An advantage of this embodiment is that, for example, the module element can be arranged on a structural unit. A plurality of further module elements can then be arranged on the module element. Thus, a signal and / or energy can be transmitted from the structural unit via the module element to the plurality of functional elements.

[0056] Preferably, the module element has a plurality of conduction paths arranged based on the predetermined orientation.

[0057] An advantage of this embodiment is that a plurality of different signals can be transmitted by means of the same module element through the plurality of conduction paths, which are arranged in particular partly horizontally and partly vertically in order thus to have the predetermined orientation.

[0058] Preferably, the first conduction path is arranged on a first layer of the module element, wherein the second conduction path is arranged on a second layer of the module element.

[0059] An advantage of this embodiment is that the manufacturing costs of the module element can be significantly reduced, since a layer with only one conduction path can be laminated, thus ensuring the same orientation for all conduction paths. The two layers can then be applied offset from one another to create the predetermined orientation between the two conduction paths.

[0060] Further preferably, the first conduction path is connected to the second conduction path by means of a through-hole through the first layer and / or the second layer. An advantage of this embodiment is that, using a standard through-hole connection, the first conduction path can be connected to the second conduction path in a signal- and / or power-conducting manner, further reducing the manufacturing costs of the module element.

[0061] Further preferably, the module element is connectable to a structural unit, wherein the first conduction path is configured to connect the module element to the structural unit and / or a further module element in a signal-conducting and / or energy-conducting manner.

[0062] An advantage of this embodiment is that the module element can be connected to a structural unit that, for example, provides a voltage and / or current. The voltage and / or current can then be transmitted via the module element to another module element using the first conduction path. Furthermore, signals can also be transported, for example, from another module element via the module element to the structural unit and vice versa.
