DETAILED DESCRIPTION

[0033] The following description is of various example embodiments only, and is not intended to limit the scope, applicability or configuration of the present disclosure in any way. Rather, the following description is intended to provide a convenient illustration for implementing various embodiments including the best mode. As will become apparent, various changes may be made in the function and arrangement of the elements described in these embodiments, without departing from the scope of the appended claims. For example, the steps recited in any of the method or process descriptions may be executed in any order and are not necessarily limited to the order presented. Moreover, many of the manufacturing functions or steps may be outsourced to or performed by one or more third parties. Furthermore, any reference to singular includes plural embodiments, and any reference to more than one component or step may include a singular embodiment or step. Also, any reference to attached, fixed, connected or the like may include permanent, removable, temporary, partial, full and/or any other possible attachment option. As used herein, the terms “coupled,” “coupling,” or any other variation thereof, are intended to cover a physical connection, an electrical connection, a magnetic connection, an optical connection, a communicative connection, a functional connection, and/or any other connection.

[0034] For the sake of brevity, conventional techniques for mechanical system construction, management, operation, measurement, optimization, and/or control, as well as conventional techniques for mechanical power transfer, modulation, control, and/or use, may not be described in detail herein. Furthermore, the connecting lines shown in various figures contained herein are intended to represent example functional relationships and/or physical couplings between various elements. It should be noted that many alternative or additional functional relationships or physical connections may be present in a modular structure.

[0035] Disclosed herein, is an adaptable battery management system that is flexible and extensible. “Extensible”, as described herein, refers to a battery system architecture that is designed to allow the addition of new capabilities and functionality. In various embodiments, the adaptable battery management system may provide an ability for a battery pack manufacturer to apply combinations of standard modules with the adaptable battery management system in a reconfigurable manner. In other words, the battery management system may be adaptable to various sizes and configurations of interconnected battery modules with little to no changes to the termination modules of the adaptable battery system, as described further herein.

[0036] In various embodiments, the battery management system allows flexibility in a battery system. For example, a number of battery modules in a string may be varied, a number of strings in parallel may be varied, and a number of loads of the battery system may be varied, in accordance with various embodiments.

[0037] In various embodiments, the reconfigurable nature of the battery management system may provide integrated protection capabilities through distributing protection functions throughout the battery system (e.g., protection functions distributed between termination blocks).

[0038] In various embodiments, the adaptable battery management system disclosed herein may be customizable to various battery applications and designs with little upfront costs for integration. In various embodiments, the reconfigurable nature of the battery management system may produce economies of scale on pricing of battery systems with the adaptable battery management system. In various embodiments, by having similar components for the adaptable battery management systems in various applications and platforms, maintenance time and costs may be reduced.

[0039] In various embodiments, the adaptable battery management system of the battery system disclosed herein includes a high side termination module and a low side termination module. In various embodiments, the adaptable battery management system may perform various functions associated with a typical battery management system through distinct, and independent components (e.g., the high side termination module, the low side termination module, and/or a midpoint termination module). For example, a control system for a string of battery modules may be disposed in the high side termination module and a fuse plug may be disposed in the low side termination module, in accordance with various embodiments. Although described herein as having specific components in specific termination modules, the present disclosure is not limited in this regard. For example, any component may be disposed in any of the respective termination modules (e.g., high side, low side, and/or mid-point termination modules), and any function may be performed by any of the respective termination modules (e.g., high side, low side, and/or mid-point termination modules), in accordance with various embodiments.

[0040] In various embodiments, each module in the battery management system may have a common interface with interconnected battery modules of the battery system. In this regard, any module (e.g., high side termination module, low side termination module, mid-point termination module, or interconnected battery module) could be electrically and mechanically coupled to any other module (e.g., high side termination module, low side termination module, mid-point termination module, or interconnected battery module). In various embodiments, the common interface may be accomplished without a wiring harness but through a direct module to module physical connection. In this regard, in various embodiments, wiring can be eliminated from the adaptable battery management system. Although described herein as having a potential to eliminate wiring, the present disclosure is not limited in this regard, and an adaptable battery management system that includes wiring at some locations is still within the scope of this disclosure.

[0041] An adaptable battery management system, as disclosed herein may comprise a battery bus, a battery control system, a sensor (e.g., a current sensor), a fuse, contactors (e.g., pre-charge contactor and/or electrical contactor), and charging interface(s). In various embodiments, the adaptable battery management system may include the above elements in separate distinct termination modules, as described further herein. In this regard, the adaptable battery management system may be more compact relative to a typical battery management system that is centrally located, in accordance with various embodiments. In various embodiments, the adaptable battery management system may be reconfigurable for various voltage and current specifications. Battery modules for typical battery management systems are designed and customized to fit a respective battery management system. In various embodiments, integrating typical battery management systems with typical battery modules may result in long wiring harness routings to provide the centrally managed distribution, which may add weight and reduce robustness of the battery system. In various embodiments, the adaptable battery management system disclosed herein may facilitate a non-wired battery system with hard, physical, connections (e.g., without the use of wireless signals or communication through an unguided communication), but without external wire or cable harnesses except those providing power or communications with the vehicle. “Non-wired” as disclosed herein means without external physical wires / cables. “Non-wired” as disclosed herein includes maintaining a physical electrical path.

[0042] Also disclosed herein are battery modules (and termination modules) having common interfaces for a battery system (e.g., a charging system and/or an aircraft battery system). For example, the charging system may have a plumbing system, a communication system, a venting system, and/or electrical connections between adjacent battery modules. Similarly, the aircraft battery system may have a plumbing system, a communication system, a venting system, and/or electrical connections between adjacent battery modules. Locally, couplings between external components of the charging system to a respective module (e.g., battery module, termination module, or the like) may be identical, or nearly identical to facilitate assembly and ease of reconfigurability.

[0043] Referring now to FIG. 1A, a perspective view of an interconnected battery module (“ICBM”) 20 is illustrated, in accordance with various embodiments. In various embodiments the ICBM 20 includes a housing 22 and a plurality of cells disposed within the housing 22. The plurality of cells are in electrical communication with power connections 24 disposed on opposite sides of the housing 22. The power connections 24 include a positive terminal and a negative terminal. In various embodiments, the plurality of cells are a plurality of pouch cells, a plurality of cylindrical cells, a plurality of prismatic cells, or the like. The present disclosure is not limited in this regard. In various embodiments, the power connections 24 are configured to physically, and electrically coupled the ICBM 20 to an adjacent ICBM 20. The ICBM 20 can further comprise mechanical connections 26. In this regard, the mechanical connections 26 can provide structural stability between adjacent ICBMs in a battery system as described further herein.

[0044] In various embodiments, the power connections 24 include a positive terminal on a first side and a negative terminal on a second side opposite the first side. The positive terminal is configured to electrically and physically couple to a negative terminal of an adjacent ICBM in an interconnected battery system described further herein. Similarly, the negative terminal is configured to electrically and physically couple to a positive terminal of an adjacent ICBM in an interconnected battery system. In this regard, the ICBMs of an interconnected battery system may be configured for electrical and physical coupling in series electrically and may be configured with an additional component to create a parallel electrical connection, in accordance with various embodiments. The present disclosure is not limited in this regard. For example, the interconnected battery system may be configured to couple adjacent ICBMs in parallel as a default configuration instead of in series as a default configuration and still be within the scope of this disclosure.

[0045] In various embodiments, the housing 22 includes a vent connection 30. In various embodiments, the vent connection 30 is configured to fluidly couple a vent port 31 to an exhaust system for a battery system as described further herein. In this regard, the vent connection 30 may comprise a common interface with an exhaust system for multiple battery systems, as described further herein, to facilitate swapping between battery systems for secondary life, or for primary life after being in inventory, in accordance with various embodiments. The vent port 31 comprises a fluid outlet in fluid communication with an internal cavity of the housing 22. The plurality of cells are also disposed in the internal cavity. In this regard, any ejecta, gases, or foreign object debris (“FOD”) from a thermal runaway event may be configured to be expelled out the vent port 31 and into an exhaust system of a respective battery system. In various embodiments, the vent connection 30 is disposed on atop surface of the housing.

[0046] In various embodiments, the housing 22 of the ICBM 20 comprises mounting connections 40 (e.g., physical mounting connections). The mounting connections 40 are configured to mount to a support structure in a respective battery system. In various embodiments, the mounting connections 40 may be disposed on opposite sides of the housing 22. However, the present disclosure is not limited in this regard. The mounting connections 40 may comprise a common interface with a support structure for multiple battery systems (e.g., a charging system and an electrically powered propulsion system), as described further herein.

[0047] In various embodiments, the ICBM 20 further comprises battery management connections 42. The battery management connections 42 may comprise daisy chain communication interfaces or the like. In this regard, the battery management connections 42 are configured to interface with adjacent ICBMs in accordance with ICBM 20 in a battery system and communicate data from the ICBM 20 down a line of adjacent ICBMs. In an example embodiment, the data from the various ICBMs is communicated to a master battery management system, in accordance with various embodiments. However, in other example embodiments, the battery management system is implemented in a distributed manner, or otherwise. This method of data communication may facilitate installing adjacent array of battery modules and maintaining data communication for a battery management system for various battery systems (e.g., a charging system and an electrically powered propulsion system), as described further herein.

[0048] In various embodiments, the ICBM 20 further comprises thermal management connections 44. The thermal management connections 44 are fluid connections, such as fittings, adapters, ferrules, or any type of fluid coupling known in the art. In various embodiments, the thermal management connections 44 comprise an inlet fitting 45 and an outlet fitting 46. In this regard, the ICBM 20 is configured to receive a fluid from the inlet fitting 45, which travels through the housing 22 and is configured to cool or heat a plurality of cells disposed within the housing 22, in accordance with various embodiments. In various embodiments, the thermal management connections 44 are adaptable to a battery system for an aircraft and adaptable for a charging system (e.g., a mobile charging system) as described further herein.

[0049] In various embodiments, as described further herein, termination modules can comprise similar, or the same connections of the ICBM 20. For example, with reference now to FIG. IB, a battery management module 50 (e.g., termination modules 112, 114, 116, 118, 119, paralleling modules 512, 514, 522, 524, 532, 534, etc. as disclosed further herein) can comprise a housing 52, power connections 24, mechanical connections 26, mounting connections 40, battery management connections 42, and/or thermal management connections 44. In this regard, the termination module 50 can be configured to be electrically and physically coupled to an ICBM 20 as described further herein, in accordance with various embodiments. Although illustrated with thermal management connections 44, the present disclosure is not limited in this regard. For example, the battery management module 50 may not include thermal management connections 44 and be within the scope of this disclosure.

[0050] In various embodiments, by having common interfaces between the termination module 50 and the ICBM 20, the stack-ability and/or reconfigurability of battery systems and battery managements systems can be facilitated, as described further herein. In various embodiments, the various connections of the battery management module can be rearranged on the housing 52 as disclosed further herein (e.g., two sets of power connection connections 24 could be provided for termination module 118 and/or termination module 119) to facilitate coupling to two distinct ICBMs (e.g., two distinct of ICBM 20).

[0051] Referring now to FIGs. 2A and 2B, a schematic view of a battery system

100 (FIG. 2A) and a perspective view of a battery system 100 (FIG. 2B) with an adaptable battery management system 110 are illustrated, in accordance with various embodiments. The battery system 100 comprises the adaptable battery management system 110 and interconnected battery modules (“ICBMs”) 120 (e.g., ICBM 20 from FIG. 1A). In a configured state, the ICBMs 120 are disposed between a first termination module 112 (e.g., high side termination module) of the adaptable battery management system 110 and a second termination module 114 (e.g., low side termination module) of the adaptable battery management system 110. In various embodiments, “high side” as described herein may refer to an electrically positive end of a sequence of ICBMs 120 and a “low side” may refer to an electrically negative end of a sequence of ICBMs 120 in a battery system 100.

[0052] In various embodiments, the adaptable battery management system 110 may further comprise a third termination module 116 disposed between the first termination module 112 and the second termination module 114. The third termination module 116 may further be disposed between a first set of interconnected battery modules 122 of the ICBMs 120 and a second set of interconnected battery modules 124 of the ICBMs 120. In various embodiments, the battery system 100 may comprise at least one string of battery modules 101 (e.g., the ICBMs 120 and the termination modules 112, 114, 116).

In this regard, the termination module 401 can be stackable as described herein. In various embodiments, the first side 406 can be opposite the second side 407. However, the present disclosure is not limited in this regard. For example, the second side 407 could be adjacent to the first side 406 and still be within the scope of this disclosure.

[0098] In various embodiments, a communication line 492 extends from the conductive element 482 to the communications positive terminal 264, and a communication line 294 extends from the conductive element 484 to the communications negative terminal 266.
