DETAILED DESCRIPTION

[0017] The present subject matter relates to aspects of servicing of batteries in vehicles. As an example, servicing may include removal of the batteries for repair and maintenance, placement of repaired batteries in the vehicle, as well as replacement of old batteries with new batteries in the vehicle.

[0018] Conventionally, the straddle-type vehicle has a drive system that generates traction power to move the vehicle. For instance, the vehicle is a two-wheeler, which can be an electric vehicle (EV) or a hybrid electric vehicle (HEV). Vehicles with different drive systems, such as the EV and the HEV have one or more batteries mounted to a chassis of the vehicle. One or more batteries are rechargeable, such that the energy stored in the battery drives or contributes to driving the wheels of the vehicle and are used as a source of power for the vehicle. For this reason, one or more batteries used in such vehicles have higher capacity and are therefore, considerably heavier and bigger.

[0019] Correspondingly, the chassis of the EV or HEV (hereinafter referred to as the vehicle) are designed in a manner, such that the chassis can carry the load of such batteries along with other driving components. The chassis is so designed that the components of the vehicle are mounted in an optimized arrangement, such that load/weight distribution, balance, and ride quality of the vehicle are not affected. In such conventional designs, the batteries are fixedly mounted to the chassis of the vehicle, such that the batteries mounted are not movable or dockable, and the chassis of the vehicle can withstand the load. As a result, maintenance and external service of such batteries become difficult for a user since, the battery is fixed to the vehicle and not easily removable. Consequently, the battery gets heated up which adversely affects the life span of the battery.

[0020] In certain cases, during the servicing of the vehicle or maintenance of the vehicle the batteries are removed from the vehicle. However, conventional designs of battery pack cause difficulties in removing and insertion of batteries integrated in the vehicle and also due to the conventional design of chassis of such vehicles, the discharging of the batteries from the vehicle becomes difficult. Additionally, the whole process of removing the battery from the vehicle and for that matter installing or swapping a new battery or a serviced battery or a recharged battery in the vehicle is cumbersome, time-consuming, and highly unsafe for the user.

[0021] The reason being, the battery packs are heavy due to weight of the battery cells inside and the battery packs of higher power rating weigh proportionally more. Therefore, appropriate provisions need to be provided for ease of removability and replacement of the battery pack, which is a necessity for battery swapping.

[0022] The present subject matter discloses examples and aspects to inter alia address the above-mentioned problems. The present subject matter, in one example, relates to servicing of batteries in vehicles. The vehicle may be a two-wheeler, three-wheeler or four-wheeler. The vehicle may be an electric vehicle (EV), or a hybrid electric vehicle (HEV). The servicing may include discharging and removing batteries for repair, maintenance, recharging or swapping, as well as replacing the old battery pack with a new battery pack in the vehicle.

[0023] According to an aspect, the vehicle may have a chassis that may be the main support structure of the vehicle and may bear all the stresses of the components assembled in the vehicle. A utility box may be provided in the chassis of the vehicle. In an example, the utility box may accommodate a battery pack, such that the utility box is covered by a lid, allowing a user to access a battery pack. In an example, the vehicle may have a seat, such that the seat may be formed with the lid. In another example, the lid may have a locking component. The locking component of the lid on the seat of the vehicle may lock and unlock the battery pack accommodated in the utility box of the vehicle. The lid may be partially supported by the batery pack. In an example, the batery pack may include at least one batery. The batery pack may have at least one connector, in order to connect the at least one batery of the batery pack with the vehicle, such that the power from the batery pack may be used as a power source to move the vehicle.

[0024] According to an aspect, the chassis of the vehicle may be so designed that the chassis has a head pipe connected through a floorboard structure to a rear frame structure. The rear frame structure may have a pair of side tube and a sub-frame structure. The sub-frame structure may be mounted to the pair of side tubes. In an example, the sub-frame structure is mounted to the pair of side tubes of the rear frame structure, making the sub-frame structure a part of the chassis of the vehicle. In other example, the sub-frame structure may have a batery box. The batery box may accommodate the batery pack.

[0025] According to other aspect, the batery pack may include at least one batery, a batery holder assembly, a handle base assembly and at least one handle. In an example, the batery holder assembly may be wrapped about the at least one batery, such that the batery holder assembly may be placed in the batery box of the vehicle to install the batery pack in the vehicle. In another example, the batery handle assembly may be wrapped about the at least one batery along a height direction of the at least one batery, in order to support and hold the at least one batery.

[0026] In other example, the batery holder assembly may have a plurality of straps that may be wrapped around the at least one batery. In an example, the batery holder assembly may be fabricated from a sheet metal of mild steel, thereby making the batery holder assembly thermally and electrically insulating. The plurality of the straps of the batery holder assembly may include a base strap, one or more left-hand straps and one or more right-hand straps. The base strap may support the at least one batery at a base thereof. In an example, the base strap may have a body portion and a first extension which runs orthogonally from the body portion. In an example, the first extension may be provided at one end of the body portion and can be orthogonal with respect to a length dimension of the body portion. As a result, the first extension can further hold and lock the batery positioned in the batery holder assembly by preventing any movement and sliding of the batery in the sideways direction. The one or more left-hand straps and the one or more right-hand straps may hold and cover the batery, as it extends from the base strap towards to the top of the batery, i.e., along the height of the at least one batery. In an example, the one or more left-hand straps and the one or more right-hand straps may be solid. In other example, the one or more left-hand straps and the one or more right-hand straps may be perforated, thereby reducing the overall weight of the vehicle, when the battery pack of the present subject matter is installed in the vehicle. In another example, either the one or more left-hand straps or the one or more right-hand straps, may have a connector strap extending orthogonally from their respective centers. In another example, the one or more left-hand straps or the one or more right-hand strap both may have the connector strap extending orthogonally from their respective centers. In an example, the connector strap may orthogonally connect the one or more left-hand straps and the one or more right hand straps. In other example, the connector strap may have a second extension that may lock and restrict any movement of the battery sideways. The second extension of the connector strap may be orthogonal from body portion of the connector strap. In an example, the second extension of the connector strap may be provided at one end of the body portion and can be orthogonal with respect to a length dimension of the body portion. In one of the examples, the second extension is designed to have a bend between the body portion of the connector strap and the second extension. The bend of the second extension may aid in accommodating the shape of the battery and to hold the battery tightly. As a result, the second extension can further hold and lock the battery positioned in the battery holder assembly by preventing any movement and sliding of the battery in the sideways direction. In an example, the first extension and the second extension may be positioned at opposite ends of the battery holder assembly, thereby locking and preventing the movement of the battery from both lateral ends of the battery pack.

[0027] The battery pack, in which battery holder assembly accommodating the at least one battery, may be positioned inside the bottom of the battery box. The battery box may carry the complete load of the battery pack. In another example, the battery box may have a welding nut positioned at bottom of the battery box, such that the battery box may be fastened through a plurality of attachment means (not shown) to the subframe, in which the subframe is fastened and bolted to the chassis of the vehicle.

[0028] In another example, the battery holder assembly may have at least one swingable bracket that may be pivoted at one of the one or more left-hand straps and at one of the one or more right-hand straps. The swingable bracket may have a support bracket in order to support at least one connector of the battery pack. The support by the support bracket of the swingable bracket may provide rigidity and appropriate support to the at least one connector and may also reduce the chances of unplugging the connection of the at least one connector with the vehicle because of the movement of the vehicle.

[0029] In an instance of servicing of the at least one battery, the at least one connector may be unplugged before removing the battery pack from the vehicle. In another instance of servicing of the at least one battery, the battery pack may be lifted into the vehicle and may be positioned in the vehicle, in a spot in which the battery pack may be locked in the battery box and the at least one connector may be plugged with the battery pack, and may be locked in by a support bracket of the battery pack.

[0030] In an instance, the one or more left-hand straps and the one or more right-hand straps may be connected orthogonally with respect to the base strap and extending along the height of the at least one battery. In such an instance, the one or more left-hand straps and the one or more right-hand straps may be positioned offset with respect to each other. In this manner, the present subject matter may achieve compact packaging, as the requirement of changing the dimensions of the battery box be addressed, as the conventional dimensions of the battery box may be able to cater the requirement. This may be possible as the plurality of straps of at least one battery of the battery pack may align between the space of the straps of the other at least one battery of the battery pack. As a result, compactness may be achieved. The battery holder assembly of the present subject matter is designed as such that the battery holder assembly may securely carry the at least one battery accommodated inside the battery pack, such that the battery holder assembly arrests any kind of movement and vibration of the at least one battery as the vehicle is in motion.

[0031] The handle base assembly of the battery pack may be connected with the battery holder assembly at a top of the at least one battery. In an example, the handle base assembly may be fabricated using polyamide material. In other example, the handle base assembly may connect the at least one handle and the battery holder assembly. In other words, the handle base assembly may act as a connecting medium between the battery holder assembly and the at least one handle. The handle base assembly may be positioned above the battery holder assembly with the help of attachment components, such as the handle base assembly may have an insert to hold the fastener. This way, the handle base assembly reduces the friction and allows easy movement of the battery pack. The handle base assembly may also act as a supporting member connecting the battery holder assembly and the at least one handle.

[0032] In one example, the at least one handle may be pivotably connected to the handle base assembly. In one example, the at least one handle may be foldable against the top of the at least one battery. The at least one handle may be attached to the handle base assembly using the attachment components including, fasteners.

[0033] In an instance, the at least one handle may have a plurality of magnetic locks provided therein, such that the movement of the at least one handle may be arrested. The plurality of magnetic locks may aid in avoiding any noise because of the vibration caused by the movement of the vehicle.

[0034] The at least one handle of the present subject matter is so designed, that the at least one handle is user friendly and provides a simple mechanism to lift the battery pack to and from the vehicle for servicing and also aids in easy lifting and easy servicing of the battery pack to and from the vehicle. This may be possible as the at least one handle may be designed to have a grip like design in order to ensure a reduction in weight distribution over the fingers of a user, that may be lifting the battery pack through the at least one handle. The at least one handle of the present subject matter may also ensure the swinging motion. In other words, the at least one handle may allow user to easily lift and move the battery pack, thereby ensuring a swinging motion of the battery pack while servicing of the battery pack. As a result, saving extra space inside the vehicle.

[0035] The servicing may include servicing of the battery in the vehicle, including maintenance of the battery in the vehicle, swapping of the battery, removing the battery from the vehicle for recharging or replacement. In an example, the servicing may include removing, swapping or replacing the battery from the vehicle. In other example, the servicing may include removing, swapping or replacing the battery to the vehicle after servicing, maintenance, recharging the battery, or for just the purpose of reinstalling or installing.

[0036] In view of the above exemplary embodiments and aspects, the at least one battery may be easily serviced, such that the battery pack may be easily moved to and from the vehicle in a minimal time. As a result, charging of the battery pack becomes easy since the battery pack may be removed from the vehicle, and it is possible to charge the same at any point in time and also at any place. Further, the battery pack of the present subject matter ensures that the connecter is plugged and locked, when the battery pack is positioned inside the vehicle. The present subject matter uses less number of parts and enables servicing of the at least one battery of the vehicle, without use of any complex components. Therefore, the maintenance and external service of such batteries becomes easier for a user since, the battery pack accommodated in the battery box of the vehicle may be easily discharged and moved, and this may be possible because of the battery holder assembly that may carry the load of the at least one battery, the handle base assembly that may ensure to reduce friction and allow easy movement of the battery pack by the user holding the at least one handle, where the at least one handle may reduce weight distribution on the fingers of the user while lifting the battery pack, thereby allowing the battery pack to be lifted with ease and ensuring easily moving and swinging the battery pack to and from the vehicle. With the above-mentioned configuration, an easier, safer and less-time consuming process of servicing the battery pack, one of towards and from the vehicle can be achieved.

[0037] In addition to the above, the present subject matter reduces battery assembling and discharging time, as stand by battery packs may be serviced separately at any place and as per user’s requirements at the time and may be replaced/swapped in the vehicle with the lesser time. Additionally, the present subject matter allows swapping and replacement of the battery in minimal time as possible. Further, the present subject matter implicitly improves the performance and durability of the vehicle, since the battery pack may be easily serviced and the vehicle may not be heated up. Further, the perforations on the plurality of straps of the battery holder assembly reduces the overall weight of the vehicle as the battery pack of the present subject matter is installed in the vehicle. Further, initial level maintenance, external services, and cleaning of the battery of the vehicle is easier. The present subject matter allows EV and HEV to be used as a multipurpose vehicle and allows the vehicle to be adopted for commercial purpose also such as but not limited to E-commerce purposes.

[0038] The above aspects are further illustrated in the figures and described in the corresponding description below. It should be noted that the description and figures merely illustrate principles of the present subject matter. Therefore, various arrangements that encompass the principles of the present subject matter, although not explicitly described or shown herein, may be devised from the description and are included within its scope.

[0048] In other example, the sub-frame structure 207 may accommodate at least one battery box 208. The battery box 208 may carry the total load of the battery box 208 that may be connected through attachment means (not shown), such as fastener or the like, with the subframe structure while in the resting position.

[0049] Fig. 3 A illustrates an exploded view of the battery pack 102 and the battery box 208, in accordance with an example of the present subject matter. Fig. 3B illustrates a side view of the battery pack 102, in accordance with an example of the present subject matter. Fig. 3C illustrates a side view of the battery holder assembly 302, the handle base assembly 304 and at least one handle 306 of the battery pack 102, in accordance with an example of the present subject matter. Fig. 3D illustrates a top-side view of the battery holder assembly 302, the handle base assembly 304 and at least one handle 306 of the battery pack 102, in accordance with an example of the present subject matter. Fig. 3E illustrates a top view of the battery holder assembly 302, the handle base assembly 304 and at least one handle 306 of the battery pack 102, in accordance with an example of the present subject matter. Fig. 3F illustrates a bottom view of the battery holder assembly 302 of the battery pack 102, in accordance with an example of the present subject matter. For the sake of brevity, Figs. 3A-3F have been explained in conjunction with each other.

[0050] According to other aspect, the battery pack 102 may be positioned in the battery box 208 of the vehicle 100. The battery pack 102 may include at least one battery 301, a battery holder assembly 302, a handle base assembly 304 and at least one handle 306. In an example, the battery holder assembly 302 may have composition of a sheet metal part that may be bent to cover and carry for servicing the at least one battery 301. In an example, the battery holder assembly 302 may be designed as such, that the battery holder assembly 302 may act as supportive member for the battery pack 102.

[0051] In an example, the battery holder assembly 302 may be wrapped about the at least one battery 301, such that the battery holder assembly 302 may be placed in the battery box 208 of the vehicle 100 after servicing or while installing the battery pack 102 in the vehicle 100. In an example, the battery holder assembly 302 that may carry and hold the at least one battery 301 in the battery box 208, may carry the total load of the at least one battery 301. As an example, servicing may include removal of the batteries for repair and maintenance, placement of repaired batteries in the vehicle, as well as replacement of old batteries with new batteries in the vehicle. In another example, the battery holder assembly 302 may be wrapped about the at least one battery 301 along a height direction of the at least one battery 301, in order to support and hold the at least one battery 301.

[0052] In other example, the battery holder assembly 302 may have a plurality of straps that may be wrapped around the at least one battery 301. In an example, the battery holder assembly 302 may be fabricated from a sheet metal of mild steel, thereby making the battery holder assembly 302 thermally and electrically insulating. The plurality of the straps of the battery holder assembly 302 may include a base strap 303, a connector strap 316, one or more left-hand straps 302-1 and one or more right-hand straps 302-2. The base strap 303 may support the at least one battery 301 at a base thereof. In an example, the base strap 303 may have a body portion and a first extension 305, which runs orthogonally from the body portion. In an example, the first extension 305 may be provided at one end of the body portion and can be orthogonal with respect to a length dimension of the body portion. As a result, the first extension 305 can further hold and lock the battery 301 positioned in the battery holder assembly 302 by preventing any movement and sliding of the battery 301 in the sideways direction. The one or more left-hand straps 302-1 and the one or more right-hand straps 302-2 may hold and cover the battery 301, as it extends from the base strap 303 towards the top of the battery 301, i.e., along the height of the at least one battery 301. In an example, the one or more left-hand straps 302-1 and the one or more right-hand straps 302-2 maybe solid, as shown in Fig. 3B-3E. In other example, the one or more left-hand straps 302-1 and the one or more right-hand straps 302-2 may be perforated, as shown in Fig. 3 A, thereby reducing the overall weight of the vehicle 100, when the battery pack 102 of the present subject matter is installed in the vehicle 100. In another example, either the one or more left-hand straps 302-1 or the one or more right-hand straps 302-2, may have the connector strap 316 extending orthogonally from their respective centers. In another example, the one or more left-hand straps 302-1 or the one or more right-hand straps 302-2 both may have the connector strap 316 extending orthogonally from their respective centers. In an example, the connector strap 316 may orthogonally connect the one or more left-hand straps 302-1 and/or the one or more right hand straps 302-2. In other example, the connector strap 316 may have a second extension 307 that may lock and restrict any movement of the battery 301 sideways. The second extension 307 of the connector strap 316 may be orthogonal from body portion of the connector strap 316. In an example, the second extension 307 of the connector strap 316 may be provided at one end of the body portion and can be orthogonal with respect to a length dimension of the body portion. In one of the examples, the second extension 307 is designed to have a bend 307-1 between body of the connector strap 316 and the second extension 307. The bend 307-1 of the second extension 307 may aid in accommodating the shape of the battery 301 and holding the battery 301 tightly in the battery holder assembly 302. As a result, the second extension 307 can further hold and lock the battery 301 positioned in the battery holder assembly 302 by preventing any movement and sliding of the battery 302 in the sideways direction. In an example, the first extension 305 and the second extension 307 may be positioned at opposite ends of the battery holder assembly 302, thereby locking and preventing the movement of the battery 301 from both lateral ends of the battery pack 102.
