The present invention claims priority from the provisional specification filed on 21/12/2017 vide application number 201711045962 entitled "Battery Slider Mechanism" which has been incorporated herein by reference in its entirety and made part of this complete specification for all purposes.
Field of invention:
The present invention relates to a battery arrangement system for an electric/hybrid vehicle that is capable of quick and easy battery swapping.
Background of invention:
An electric/hybrid vehicle generally has the following parts which differentiate it from a vehicle running on an internal combustion engine:
1. Traction motor;
2. An energy storage system (ESS) in the form of a battery pack;
3. Controller;
4. Wiring harness.
The battery packs used in such vehicles have the following disadvantages:
1. The packs are fitted in places with little or no access for maintenance.

2. The packs cannot be easily swapped if the battery loses its capacity.
3. The battery packs are not designed to be rugged since they are mostly kept in confined places inside the vehicle.
4. The life-cycle of a battery pack is limited and loses performance over time.
5. The battery packs have a bulky design which makes the process of their replacement even more cumbersome.
In addition to the above stated disadvantages, most of the present-day electric/hybrid vehicles operate with a single battery pack. The drawback with a single battery pack to power an electric/hybrid vehicle is that it comes in large sizes and are generally very expensive. This can be detrimental in terms of a swapping environment since the vehicle can be completely disengaged if that particular battery pack stops working and since these battery packs are of larger sizes and weight, the facility of accommodating a spare battery pack is also not possible. Economically too, a single battery powered electric vehicle is a downside since the user has to incur huge amounts to replace the battery pack if it goes defective.
Prior art CN101890901A discloses an electric automobile power battery quick-change mechanism which comprises of a battery installing frame. One side of the battery installing frame is pivoted on the automobile chassis through a horizontal connecting shaft, the bottom of the battery installing frame is provided with a lifting mechanism which can drive the battery installing frame to rotate around the horizontal connecting shaft,

and the other side of the battery installing frame opposite to the horizontal connecting shaft is provided with a battery pack inlet. The battery pack passing through the battery pack inlet is loaded to and unloaded from the battery installing frame through a sliding mechanism between a bottom board of the battery installing frame and the bottom surface of the battery pack, and a sliding stop mechanism capable of stopping the sliding of the battery pack is arranged in the battery installing frame corresponding to the battery pack inlet.
The prior art US20160107619A1 refers to a battery swapping system and techniques comprising of a battery pack lift system and a method of exchanging a battery pack of a vehicle. Battery packs are swapped by the lifting system once the vehicle is positioned over a ramp and a frame attached to the lifting system further helps in replacing the battery pack.
However, the above stated prior arts do not give a solution for an ideal battery arrangement system capable of acting as single energy source, facilitating multiple battery packs and offering a simple method of battery swapping through a swapping mechanism.
The present invention devises to overcome the disadvantages of the prior art by formulating an effective battery system arrangement in an electric/hybrid vehicle. The system shall consist of integrating several smaller battery packs to form a single energy hub to power the vehicle with the capability of effectuating a relatively easy battery swapping procedure. Moreover, since energy is stored in multiple small battery packs, there is

the added advantage of keeping spare battery packs within the vehicle for an emergency ensuring that the vehicle does not remain disengaged if a battery pack stops working.
Objective of invention:
An objective of the present invention is to provide a sliding mechanism for an easy removal and insertion of the battery pack/packs.
Another objective of the present invention is to reduce the battery swapping time in the vehicle.
Another objective of the present invention is to create a backup energy in case of failure of batteries.
Another objective of the present invention is to improve the weight distribution of the vehicle by keeping the battery packs between the long members of the chassis of the vehicle.
Further objects and advantages of this invention will become apparent from consideration of the drawings and descriptions that follow.
Statement of invention:
The present invention relates to a battery system arrangement for an electric vehicle capable of a sliding mechanism for easy removal and insertion of a multitude of battery packs with minimal infrastructure,

labour and cost. The system consists of integrating several relatively smaller battery packs to form a single energy hub to power the electric/hybrid vehicle with the capability of effectuating a relatively easy battery swapping procedure.
Further objects, features and advantages of the invention will become apparent from the following description when taken in conjunction with the accompanying drawings.

The following describes essential components and the arrangement of the components of the battery slider system:
1. C Channels (1): C-Channels are standardized channel sections. C-Channels (1) in stainless steel are used not only in commerce and industry but also in machinery and equipment building. The use of stainless-steel profiles is characterized by a high flexibility of composition and a fast and cost reduced construction (through the possibility of prefabrication in the steel production). Stainless steel profiles are produced mainly from scrap and can be recycled again after utilization so new resources can be conserved. The following austenitic grades are predominantly used for stainless steel structurals: 304, 304L, 316, 316L, they are defined by ASTM A276, ASTM A479 and ASME SA479.
4 C-channels (1) of dimensions that are in alignment with the vehicle (10) are built onto the chassis (11) on a longitudinal axis of the vehicle (10). They are positioned in such a manner so as to accommodate battery trays (3) on either side of the vehicle (10). The configuration of the C-channels (1) on the chassis (11) acts as the main support link between the vehicle (10) and the battery packs (6/9) and enables easy sliding of the battery packs (6,9) into the vehicle (10) thereby enabling

easier access and increasing swappable character of the battery packs (6,9)
2. Battery Trays (3): Trays with dimensions matching the battery packs
(6/9) are used to support the battery packs on the C-Channels (1). They
further consist of:
i) Roller bearings (2): Roller bearings are attached to the four
bottom corners of the battery tray (3) for their movement within
the C-Channels (1). The roller bearings (2) help the battery packs
once they are attached to the trays (3), to be easily slid in or out
of the vehicle (10) through the C-Channels (1). In the instant
example, the roller bearings (2) have diameter of 70 mm. The
stated size of the roller bearings (2) is only exemplary in nature
and do not restrict the scope of the instant invention.
ii) Steel brush (5): A brush with steel bristles is attached to the roller bearings (2) to help in preventing accumulation of dust particles in the C-channels (1) by sweeping off any residual dust while the tray (3) is slid out from the C-Channels (1).
iii) Battery locks (12): A knob lock is attached to every battery tray (3) that helps in locking the battery pack to the tray (3). Battery locks (12) helps in keeping the battery packs (6/9) intact with the battery trays (3).

iv) Connector Locks (4): A battery tray (3) can be connected to an adjoining battery tray (3) with the help of connector locks (4). This connection helps in battery swapping as pulling out one battery tray (3) will subsequently pull out the remaining adjoining battery trays (3).
6 battery Trays (3) with 3 battery trays (3) configured on each side shall be used to install the battery packs to the vehicle (10). The 3 trays (3) shall be connected with each other through the connector lock (4) that can help in connecting and detaching with any interconnected trays (3). In the instant example each tray has a dimension of 1900*300*3mm The stated size of the battery tray (3) is only exemplary in nature and do not restrict the scope of the instant invention.
3. Battery Packs (6): Relatively smaller battery packs attached to position of the battery trays (3) are connected in parallel (16SP6) to produce the desired output. Each battery pack consists of 16 cells in series making it a 51.2V battery pack with 72Ah capacity. Six similar battery packs are in parallel making it 16SP6 configuration with 51.2 net voltage and 432Ah capacity making it a 22Kwh energy source. In the instant example, each battery pack has a dimension of 600*300*200mm The said number of cells, size, configuration, voltage and capacity are only exemplary in nature and do not restrict the scope of the instant invention. The configuration of the battery packs along the

longitudinal axis of the vehicle (10) in the given arrangement boosts the overall weight distribution of the vehicle (10). Moreover, since the battery packs are relatively small, additional or spate battery pack/packs can be maintained to ensure that the vehicle (10) can be kept moving in case if one battery pack fails or gets disengaged completely. This can be achieved by storing additional battery pack on an empty unutilized space in the vehicle (10) such as a space used for storing a spare tyre.
4. Secure Bolts (7): A set of bolts are placed once the battery packs (6) are placed inside the vehicle (10) for additional protection to ensure the battery packs always remain within the C-channels (1) during movement.
In different implementations, different types of batteries can be swapped depending upon the state and condition of the batteries. For example, in an embodiment used battery pack(s) shall be replaced with newly charged /unused battery pack(s). Similarly, damaged/depleted battery pack(s) can be swapped with partially charged replacement battery pack(s).
In addition to the components, mentioned in the battery arrangement system, two additional components are necessary for facilitating swapping:

• The jacking system (13): A system comprising of jacks and jack stands such as floor jack, hydraulic bottle jack, scissor jack and the like.
• A lifting structure (8): Invention may comprise of trolley/linkages/rotating joints/elevators and the like.
The following are the steps involved in swapping the battery system arrangement. The steps mentioned below elucidate how a battery pack (6/9) is swapped in a vehicle (10) that has incorporated the battery arrangement system into its design. Also, for the instant embodiment, the lifting structure (8) shall comprise of a trolley.
• An empty trolley (8) is placed besides the vehicle (10) that contains used battery packs (6).
• The secure bolt (7) is loosened and the tray (3) at the rear end is pulled to the extent so that the used battery packs (6) with the trays protrude out. This step can take place on either rear ends of the C-channels (1) or at both depending on the requirement.
• Removing the connector lock (4) adjoining the battery tray/trays (3) and placing the battery tray consisting of the used battery pack/packs on the trolley (8).
• Removal of battery packs (6) placed near the front end of the vehicle (10) embodies removal of battery packs preceding such battery packs.

A fresh battery pack (9) is placed on the battery tray (3) which is
subsequently placed on the trolley (8) and pushed towards the
vehicle (10).
Once the trolley (8) is elevated to the position of the vehicle (10),
the fresh battery pack/packs is/are slid across the C-channel (1) and
the battery locks (12) and connector locks (4) are placed.
Subsequent battery packs (9) are inserted similarly using this
method.
The secure bolts (7) shall be placed and tightened to lock the battery
packs (6) inside the vehicle (10).
Having described but a preferred embodiment of the invention, it will be appreciated that variations can be made thereto without departing from the spirit or scope of the invention. A number of implementations have been described as examples. Nevertheless, other implementations exist and are covered by the following claims.
