PREAMBLE TO THE DESCRIPTION
The following specification particularly describes the invention and the manner in which it is to be performed.

TECHNICAL FIELD OF THE INVENTION
Present disclosure, in general, relates to a field of automobiles. Particularly, but not exclusively, the present disclosure relates to a mounting and dismounting mechanism for an energy storage device on a vehicle.
BACKGROUND OF THE INVENTION
Presently, electric vehicles using an electrical energy as a source of power are being increasingly acceptable as an alternative for the vehicles using fossil fuel. Electric vehicles create less pollution than internal combustion (i.e., gasoline and diesel powered) vehicles and hence are an environmentally friendly alternative.
Typically, electric vehicles are equipped with at least one traction battery module that provides the energy required to power their electric drive systems and drive the vehicle. Generally, a necessary operational aspect of electric vehicles is the periodic recharging of the battery module. Conventionally, the efficient recharging of the battery module requires hours and is often done overnight or while the electric vehicle is parked for a significant time. Particularly, the batteries are recharged by connecting to an electrical outlet at a particular charging station. These electric vehicles need to recharge during periods of non-use in order to be charged for and ready for use. However, due to limited number of charging, the scheduling of battery module charging for the electric vehicle becomes difficult for timely recharging of the electric vehicles. Thus, some electric vehicles are provided with provisions that are adapted for removing the depleted battery module from the vehicle and replacing the same with a fully charged replacement battery module, to replenish power in the vehicle or to address malfunction in the current battery module. Various systems have been developed that facilitates in battery module replacement from the vehicle whenever required.

In existing battery replacement system for electric vehicles, because the battery modules are heavy, a hydraulically powered lift machines, referred as forklifts, are used to complete the battery module replacement operation. During the forklift operation, the lift arms typically needs to align with a battery housing structure for effectively replacing the depleted battery with a recharged battery module. With the known forklift operation and current battery mounting structure on the vehicle, a forklift operator makes a substantial effort and faces significant maneuverability issues for aligning the forklift arms with the mounting structure for lifting out of the depleted battery therefrom and replacing it with a fully charged replacement battery module. This involves a lot of time for battery module replacement from the vehicle. In some scenario, the battery modules, typically, gets damaged during battery replacement due to non-alignment of lift-arms with the mounting structure or when the battery modules could not get securely fastened to the mounting structure, upon replacement.
Present disclosure is directed to overcome one or more limitations stated above or any other limitations associated with the known arts.

With respect to the use of substantially any plural and/or singular terms herein, those having skill in the art can translate from the plural to the singular and/or from the singular to the plural as is appropriate to the context and/or application. The various singular/plural permutations may be expressly set forth herein for sake of clarity.
It will be understood by those within the art that, in general, terms used herein, and especially in the appended claims (e.g., bodies of the appended claims) are generally intended as “open” terms (e.g., the term “including” should be interpreted as “including but not limited to,” the term “having” should be interpreted as “having at least,” the term “includes” should be interpreted as “includes but is not limited to,” etc.). It will be further understood by those within the art that if a specific number of an introduced claim recitation is intended, such an intent will be explicitly recited in the claim, and in the absence of such recitation no such intent is present. For example, as an aid to understanding, the following appended claims may contain usage of the introductory phrases “at least one” and “one or more” to introduce claim recitations. However, the use of such phrases should not be construed to imply that the introduction of a claim recitation by the indefinite articles “a” or “an” limits any particular claim containing such introduced claim recitation to inventions containing only one such recitation, even when the same claim includes the introductory phrases “one or more” or “at least one” and indefinite articles such as “a” or “an” (e.g., “a” and/or “an” should typically be interpreted to mean “at least one” or “one or more”); the same holds true for the use of definite articles used to introduce claim recitations. In addition, even if a specific number of an introduced claim recitation is explicitly recited, those skilled in the art will recognize that such recitation should typically be interpreted to mean at

least the recited number (e.g., the bare recitation of "two recitations," without other modifiers, typically means at least two recitations, or two or more recitations). Furthermore, in those instances where a convention analogous to "at least one of A, B, and C, etc." is used, in general such a construction is intended in the sense one having skill in the art would understand the convention (e.g., "a system having at least one of A, B, and C" would include but not be limited to systems that have A alone, B alone, C alone, A and B together, A and C together, B and C together, and/or A, B, and C together, etc.). In those instances where a convention analogous to "at least one of A, B, or C, etc." is used, in general such a construction is intended in the sense one having skill in the art would understand the convention (e.g., "a system having at least one of A, B, or C" would include but not be limited to systems that have A alone, B alone, C alone, A and B together, A and C together, B and C together, and/or A, B, and C together, etc.). It will be further understood by those within the art that virtually any disjunctive word and/or phrase presenting two or more alternative terms, whether in the description, claims, or drawings, should be understood to contemplate the possibilities of including one of the terms, either of the terms, or both terms. For example, the phrase "A or B" will be understood to include the possibilities of "A" or "B" or "A and B."
In addition, where features or aspects of the disclosure are described in terms of Markush groups, those skilled in the art will recognize that the disclosure is also thereby described in terms of any individual member or subgroup of members of the Markush group.
While various aspects and embodiments have been disclosed herein, other aspects and embodiments will be apparent to those skilled in the art. The various aspects and embodiments disclosed herein are for purposes of illustration and are not intended to be limiting, with the true scope and spirit being indicated by the following claims.
