[0021] In all the accompanying drawings, the corresponding reference numerals indicate the corresponding parts. Detailed Implementation

[0022] The example configuration will now be described more fully with reference to the accompanying drawings. The example configuration is provided so that this disclosure will be thorough and will fully communicate the scope of this disclosure to those skilled in the art. Specific details, such as examples of specific components, devices, and methods, are set forth to provide a thorough understanding of the configuration of this disclosure. It will be apparent to those skilled in the art that the specific details are not required, that the example configuration may be implemented in many different forms, and that the specific details and exemplary configuration should not be construed as limiting the scope of this disclosure.

[0023] The terminology used herein is for the purpose of describing specific exemplary configurations only and is not intended to be limiting. As used herein, the singular articles “a,” “an,” and “the” may also be intended to include plural forms unless the context clearly indicates otherwise. The terms “comprising,” “including,” “containing,” and “having” are inclusive, thus specifying the presence of features, steps, operations, elements, and / or components, but not excluding the presence or addition of one or more other features, steps, operations, elements, components, and / or groups thereof. The method steps, processes, and operations described herein should not be construed as requiring them to be performed in the specific order discussed or shown, unless specifically identified as such. Additional or alternative steps may be employed.

[0024] When an element or layer is referred to as “on another element or layer,” “joined to,” “connected to,” “attached to,” or “linked to” another element or layer, it may be directly on, joined to, connected to, attached to, or linked to the other element or layer, or there may be intermediate elements or layers present. Conversely, when an element is referred to as “directly on another element or layer,” “directly joined to,” “directly connected to,” “directly attached to,” or “directly linked to” another element or layer, there may be no intermediate elements or layers present. Other terms used to describe relationships between elements should be interpreted in a similar manner (e.g., “between” vs. “directly between,” “adjacent” vs. “directly adjacent,” etc.). As used herein, the term “and / or” includes any and all combinations of one or more of the related listed items.

[0025] The terms first, second, third, etc., may be used herein to describe various elements, components, regions, layers, and / or parts. These elements, components, regions, layers, and / or parts should not be limited by these terms. These terms are used only to distinguish individual elements, components, regions, layers, or parts. Terms such as “first,” “second,” and other numerical terms do not imply order or sequence unless the context clearly indicates otherwise. Therefore, the first element, component, region, layer, or part discussed below may be referred to as the second element, component, region, layer, or part without departing from the teachings of the example configuration.

[0026] In this application, including the following definitions, the term "module" may be replaced by the term "circuit". The term "module" may refer to or be a part of an application-specific integrated circuit (ASIC), or include ASICs; digital, analog, or mixed-signal analog / digital discrete circuits; digital, analog, or mixed-signal analog / digital integrated circuits; combinational logic circuits; field-programmable gate arrays (FPGAs); processors (shared, dedicated, or grouped) that execute code; memory (shared, dedicated, or grouped) that stores code executed by the processor; other suitable hardware components that provide the functions described above; or some or all of the above combinations, such as in a system-on-a-chip.

[0027] The term "code" as used above can include software, firmware, and / or microcode, and can refer to programs, routines, functions, classes, and / or objects.

The term "group processor" includes a processor, in conjunction with an additional processor, that executes some or all of the code from one or more modules. The term "shared memory" includes a single memory that stores some or all of the code from multiple modules. The term "group memory" includes memory, in conjunction with additional memory, that stores some or all of the code from one or more modules. The term "memory" can be a subset of the term "computer-readable medium." The term "computer-readable medium" does not include transient electrical and electromagnetic signals propagating through the medium and can therefore be considered tangible, non-transitory memory. Non-limiting examples of non-transitory memory include tangible computer-readable media, including non-volatile memory, magnetic memory, and optical memory.

[0028] The apparatus and methods described in this application may be implemented, in whole or in part, by one or more computer programs executed by one or more processors. The computer program includes processor-executable instructions stored on at least one non-transitory tangible computer-readable medium. The computer program may also include and / or depend on stored data.

[0029] A software application (i.e., a software resource) can refer to computer software that enables a computing device to perform tasks. In some examples, a software application may be referred to as an "application," "app," or "program." Example applications include, but are not limited to, system diagnostic applications, system management applications, system maintenance applications, word processing applications, spreadsheet applications, messaging applications, media streaming applications, social networking applications, and game applications.

[0030] Non-transitory memory can be a physical device used for temporary or permanent storage of programs (e.g., instruction sequences) or data (e.g., program state information) for use by a computing device. Non-transitory memory can be volatile and / or non-volatile addressable semiconductor memory. Examples of non-volatile memory include, but are not limited to, flash memory and read-only memory (ROM) / programmable read-only memory (PROM) / erasable programmable read-only memory (EPROM) / electrically erasable programmable read-only memory (EEPROM) (e.g., commonly used in firmware, such as bootloaders). Examples of volatile memory include, but are not limited to, random access memory (RAM), dynamic random access memory (DRAM), static random access memory (SRAM), phase-change memory (PCM), and magnetic disks or magnetic tapes.

[0031] These computer programs (also referred to as programs, software, software applications, or code) include machine instructions for a programmable processor and can be implemented using high-level procedural and / or object-oriented programming languages ​​and / or assembly / machine languages. As used herein, the terms "machine-readable medium" and "computer-readable medium" refer to any computer program product, non-transitory computer-readable medium, apparatus, and / or device (e.g., disk, optical disk, memory, programmable logic device (PLD)) used to provide machine instructions and / or data to a programmable processor, including machine-readable media that receive machine instructions as machine-readable signals. The term "machine-readable signal" refers to any signal used to provide machine instructions and / or data to a programmable processor.

[0032] Various implementations of the systems and techniques described herein can be implemented in digital electronic and / or optical circuits, integrated circuits, specially designed ASICs (Application-Specific Integrated Circuits), computer hardware, firmware, software, and / or combinations thereof. These different implementations may include implementations in one or more computer programs executable and / or interpretable on a programmable system, the programmable system including at least one programmable processor, at least one input device, and at least one output device, the programmable processor being dedicated or general-purpose, coupled to receive data and instructions from and send data and instructions to the storage system.

[0033] The processes and logic flows described in this specification can be executed by one or more programmable processors, also known as data processing hardware, which execute one or more computer programs to perform functions by manipulating input data and generating output. These processes and logic flows can also be executed by special-purpose logic circuits, such as FPGAs (Field-Programmable Gate Arrays) or ASICs (Application-Specific Integrated Circuits). For example, processors suitable for executing computer programs include general-purpose and special-purpose microprocessors, as well as any one or more processors of any kind of digital computer. Typically, the processor receives instructions and data from read-only memory or random access memory, or both. The basic components of a computer are a processor for executing instructions and one or more storage devices for storing instructions and data. Typically, a computer will also include or be operatively coupled to one or more mass storage devices for storing data, such as magnetic disks, magneto-optical disks, or optical disks, to receive data from or transfer data to, or both. However, a computer does not need to have such devices. Computer-readable media suitable for storing computer program instructions and data include all forms of non-volatile memory, media, and storage devices, including, for example, semiconductor storage devices such as EPROM, EEPROM, and flash memory devices; magnetic disks such as internal hard disks or removable disks; magneto-optical disks; and CD-ROMs and DVD-ROMs. Processors and memory may be supplemented or incorporated therein by dedicated logic circuitry.

[0047] According to one aspect, the first cooling channel 346 and the second cooling channel 348 can be made of aluminum alloy or steel with a thickness ranging from 0.1 mm to 0.5 mm. Choosing such materials is desirable for reducing the weight and cost of each of the one or more cooling beams 300.

[0048] In this illustrative configuration, the first cooling channel 346 and the second cooling channel 348 can be arranged such that the protrusion 356 of the first cooling channel 346 aligns with and contacts the protrusion 366 of the second cooling channel 348, as shown below. Figure 5 As shown. In another configuration of the cooling beam 300', the first cooling channel 346 and the second cooling channel 348 can be staggered relative to each other. In other words, the first cooling channel 346 can be arranged relative to the second cooling channel 348 such that the protrusion 356 of the first cooling channel 346 is offset from the protrusion 366 of the second cooling channel 348, as shown. Figure 6 As shown.

[0049] Reference Figure 5 and Figure 6The battery pack 400 can be arranged such that the outer surface 324 of the first outer plate 314 contacts the first surface of a prismatic can 104, and the outer surface 336 of the second outer plate 316 contacts the second surface 116 of another prismatic can 104. In other words, one or more cooling beams 300 can be sandwiched between two or more prismatic cans 104. Furthermore, the bottom surface 326b of the first flange 326 of the first outer plate 314 can contact the upper end 110 of one prismatic can 104, while the top surface 340a of the second flange 340 of the second outer plate 316 can contact the lower end 112 of another prismatic can 104.
