Description:FIELD OF THE INVENTION
[001] Present invention generally relates to a battery box, more particularly relates to a dockable battery box carrying one or more battery modules for a vehicle.

BACKGROUND OF THE INVENTION
[002] Typically, in vehicles such as two wheeled vehicles, devices like, a battery tray or battery boxes are used for carrying / supporting one or more battery modules or battery pack of the vehicle. In such arrangements, there is a connector disposed on a casing of a battery pack. The connector on the casing could be inaccessible to a user of the battery pack, thereby making it difficult for them to recharge it. Moreover, the connector on the casing especially if the connector is on an underside of the battery pack, it is not visible to the user and can cause issues while docking and undocking it from the vehicle. With no visibility, accessibility or guiding provisions, the user is unable to simply place the battery pack in the vehicle without worrying about whether the connection is established or not, and blind mating of the connectors is not established easily. Further, the connectors on a top portion of the battery boxes may bring forth issues regarding water ingress and other complications, thereby jeopardising safety of the user. For connectors that are disposed in the top cover or any other additional covers/components, the constant pressure and “g” force that is applied to the battery pack while driving the vehicle and the vibrations felt during the movement of the vehicle often loosens the top cover or any other additional covers/components creating issues of disconnection as well as undoing the sealing of the battery pack.
Therefore, it is necessary for the connectors to be disposed in a location that overcomes these shortcomings.
[003] When the vehicle is moving, various vibrations and jerky movements can cause the battery pack to get disconnected from its connector, causing the vehicle to come to a complete stop. .
[004] In addition, without proper guiding provisions in the battery pack, the user may incorrectly dock the battery pack causing difficulties. Further, attaching and detaching the battery pack from the dock is complicated for the user. If any additional components and covers are used to keep the battery pack from moving, it would cause an increase in weight of the vehicle.
[005] Further, in existing designs, the handle grip is moulded with depressions to enable easy holding and removal of the battery pack. However, the handles due to their inability may tend to bend and get broken easily. Also, there may be an uneven distribution of weight to the handle cap and fasteners.
[006] Battery is a storage device of electricity which is used to drive an electric vehicle. Thus, in electric vehicle battery is an imperative part. Range of the battery, safety of the battery and swapping of batteries are primary requirements of electric vehicles and these things basically rely upon a sort of battery chosen and battery subsystems. In existing design, the batteries are used in the electrical vehicle as a source of charged electric power with the fixed mountings which is not movable or dockable. The battery pack is placed as stable and the size of the battery pack which is very difficult to dock the battery inside the vehicle after service.
[007] In addition to the above limitations, in electric vehicles, the battery pack’s location is under a utility box, which may be difficult to dock the battery packs.
[008] Many attempts have been made to address one or more limitations as mentioned above. In one kind of battery seat barrel assembly, it comprises a lower seat barrel and an upper seat barrel plate frame. The upper seat barrel plate frame is detachably installed on the upper end barrel opening of the lower seat barrel. The upper seat barrel plate frame is provided with a through hole for the battery to pass through. The upper end barrel opening of the through hole one and the lower seat barrel are opposite. The battery is placed in the lower seat barrel. One side of the upper cover in the battery is fixed with the plug male head. One side of the upper end barrel opening of the lower seat barrel can be upwards and downwards elastic mounting plug female seat, and the upper seat barrel plate frame corresponding to the plug female seat is provided with an avoiding gap. When placing the battery, the plug male head is inserted with the plug female seat together after avoiding the gap. However, in the battery seat barrel assembly as discussed above, there are no proper guiders allocated for the battery pack to dock in the vehicle.
[009] In yet another kind of existing storage battery connecting interface structure, it comprises a battery cylinder, wherein an upper end of the battery cylinder is connected with a top cover. The side of the battery cylinder is fixedly installed with a storage battery connecting interface. One side of the top cover is fixedly connected with an interface socket. The side of the interface socket is equipped with a key. The bottom end of the interface socket is provided with five inserting spring sheet opening. The storage battery connecting interface is provided with an inserting spring sheet inserted with the inserting spring sheet opening and is detachably connected with the interface socket through the key. However, the connector as discussed above has a button to attach and detach the battery pack that acts like a locking key that is placed at the edge of the pack that may not be easily accessible to the customer.
[010] Existing battery subsystem, include one or more impediments and they are, charging of the battery is difficult where the charging infrastructure is not equipped with the required vehicle fitted power sockets, the battery pack may slip and fall while removing it from the vehicle during the service condition, which will affect the battery pack both internally and externally. The stable design of the battery pack cause difficulties in removing and insertion of vehicle integrated batteries. Standby battery pack in the existing design requires maintenance and also external service is difficult since the overall battery pack is fixed and not easily removable. The existing battery system further requires long charging duration for the batteries to get fully charged.
[011] Thus, there is a need in the art for providing a battery box which addresses the aforementioned problems and limitations.
