[0038] At the outset, it should be clearly understood that like reference numerals are intended to identify the same structural elements, portions, or surfaces consistently throughout the several drawing figures, as such elements, portions or surfaces may be further described or explained by the entire written specification, of which this detailed description is an integral part. Unless otherwise indicated, the drawings are intended to be read (e.g., cross-hatching, arrangement of parts, proportion, degree, etc.) together with the specification, and are to be considered a portion of the entire written description of this invention. As used in the following description, the terms“horizontal,” “vertical,” “left,” “right,” “up” and “down,” as well as adjectival and adverbial derivatives thereof (e.g., “horizontally,” “rightwardly,” “upwardly,” etc.), simply refer to the orientation of the illustrated structure as the particular drawing figure faces the reader. Similarly, the terms “inwardly” and “outwardly” generally refer to the orientation of a surface relative to its axis of elongation, or axis of rotation, as appropriate.
[0039] Furthermore, it is understood that this disclosure is not limited to the particular methodology, materials and modifications described and as such may, of course, vary. It is also understood that the terminology used herein is for the purpose of describing particular aspects only, and is not intended to limit the scope of the claims.
[0040] Unless defined otherwise, all technical and scientific terms used herein have the same meaning as commonly understood to one of ordinary skill in the art to which this disclosure pertains. It should be understood that any methods, devices, or materials similar or equivalent to those described herein can be used in the practice or testing of the example embodiments.
[0041] It should be appreciated that the term “substantially” is synonymous with terms such as “nearly,” “very nearly,” “about,” “approximately,” “around,” “bordering on,” “close to,” “essentially,” “in the neighborhood of,” “in the vicinity of,” etc., and such terms may be used interchangeably as appearing in the specification and claims. It should be appreciated that the term “proximate” is synonymous with terms such as “nearby,” “close,” “adjacent,” “neighboring,” “immediate,” “adjoining,” etc., and such terms may be used interchangeably as appearing in the specification and claims. The term “approximately” is intended to mean values within ten percent of the specified value.
[0042] It should be understood that use of “or” in the present application is with respect to a “non-exclusive” arrangement, unless stated otherwise. For example, when saying that “item x is A or B,” it is understood that this can mean one of the following: (1) item x is only one or the other of A and B; (2) item x is both A and B. Alternately stated, the word “or” is not used to define an “exclusive or” arrangement. For example, an “exclusive or” arrangement for the statement “item x is A or B” would require that x can be only one of A and B. Furthermore, as used herein, “and / or” is intended to mean a grammatical conjunction used to indicate that one or more of the elements or conditions recited may be included or occur. For example, a device comprising a first element, a second element and / or a third element, is intended to be construed as any one of the following structural arrangements: a device comprising a first element; a device comprising a secondelement; a device comprising a third element; a device comprising a first element and a second element; a device comprising a first element and a third element; a device comprising a first element, a second element and a third element; or, a device comprising a second element and a third element.
[0043] Moreover, as used herein, the phrases “comprises at least one of’ and “comprising at least one of’ in combination with a system or element is intended to mean that the system or element includes one or more of the elements listed after the phrase. For example, a device comprising at least one of a first element; a second element; and, a third element, is intended to be construed as any one of the following structural arrangements: a device comprising a first element; a device comprising a second element; a device comprising a third element; a device comprising a first element and a second element; a device comprising a first element and a third element; a device comprising a first element, a second element and a third element; or, a device comprising a second element and a third element. A similar interpretation is intended when the phrase “used in at least one of” is used herein.

Pump 111 and / or fan 112 may be controlled by controller 106.
[0084] In an exemplary embodiment, battery module 90 is capable of being charged while installed on the mobile machine using, for example, AC and DC fast charging. Battery modules 90 are quickly and easily replaced in the field due to their connection with bases 70. Additionally, battery modules 90 may include different power capacities. Thus, when a job requires a larger power supply, a battery module 90 with a higher power capacity can be quickly installed on the mobile machine (as opposed to needing an entirely different mobile machine with a larger power capacity). As such, battery modules 90 provide separate and removable energy storage for a mobile machine that can be ordered / selected based on the work to be performed. Battery module 90 is thermally insulated and temperature controlled. Battery module 90 may be connected to one or more dampeners for vibration insulation / control.
[0085] The modularity of various components of mobile machine modular power system 300 allows installation of modules on many machines, for example of different sizes. Mobile machine modular power system 300 further allows for flexibility in the work that must beperformed at a worksite on a given day and reduces the total amount of devices required on a given worksite.
