TECHNICAL FIELD
Generally, the present disclosure relates to a battery pack compartment. Particularly, the present disclosure relates to a battery pack compartment opening mechanism to enable efficient insertion and extraction of battery packs.
BACKGROUND
The field of electric vehicles (EVs) has seen remarkable advancements in recent years, primarily driven by the urgent need for more sustainable transportation solutions. The vehicles, powered by electricity and typically utilizing one or more electric motors for propulsion, have emerged as a viable alternative to traditional internal combustion engine vehicles. However, one of the challenges in the EV domain is the efficient and effective management of battery packs, particularly concerning the mounting and dismounting for various functional activities like charging, maintenance, and replacement.
Battery packs are large, heavy components comprised of numerous individual battery cells and associated electronics. Battery packs stores electrical energy that powers the vehicle. The design and integration of the battery packs into EVs are complex due to various factors such as weight distribution, safety, thermal management, and ease of maintenance.
One of the significant problems associated with battery packs in EVs is the process of mounting and dismounting them. Traditionally, battery packs are integrated into the chassis of vehicle, which offers advantages in terms of stability and weight distribution. However, the integration makes the process of removing and replacing the battery pack for charging or maintenance quite cumbersome. Typically, removing and replacing requires specialized equipment and facilities, which can be time-consuming and costly. Moreover, for charging purposes, the process limits the flexibility of the vehicle owner, as charging must rely on specific locations where such facilities are available.
Conventional methods for mounting and dismounting battery packs often involve mechanical fastening systems, such as bolts and clamps. While the convention methods are relatively straightforward and cost-effective, there are several shortcomings. For instance, the convention methods can be time-consuming and require manual labor or specialized tools. Conventional methods are particularly problematic in situations where a quick battery swap is desirable, such as in commercial vehicle fleets or emergency response vehicles. Furthermore, the methods may not always provide a secure and reliable electrical connection, leading to safety concerns.
Another method involves integrating the battery pack into the structure of vehicle, commonly known as a 'skateboard' design. Such approach offers improved stability and safety but makes the battery pack inaccessible for quick swaps. The aforesaid approach also complicates the replacement process in the event of battery failure or degradation, leading to higher maintenance costs and vehicle downtime.
Safety concerns are paramount when dealing with high-voltage battery systems in EVs. The mounting and dismounting process must ensure that the battery pack is securely attached to prevent any movement during operation, which could lead to electrical connections becoming loose or damaged. Additionally, the process must protect against the risk of electrical shocks to the personnel involved in the battery swapping or maintenance procedures.
In recent times, there has been a trend towards developing modular battery systems, which allow for smaller sections of the battery to be replaced or charged independently. While such approach offers some improvement, the approach still requires mechanisms and does not fully address the need for quick and efficient battery swaps.
Therefore, there exists a need for battery pack compartment opening mechanism that overcomes the one or more problems associated with mounting and dismounting of battery packs in EVs.

FIG. 1 illustrates an arrangement 100 to mount and dismount at least one battery pack of an electric vehicle, in accordance with the embodiments of the present disclosure. The arrangement 100 comprises a battery compartment 102, a pivot mechanism 104, at least one support member 106 and other known components of a battery mounting and dismounting system/apparatus.
In an embodiment, the battery compartment 102 accommodates at least one battery pack within the electric vehicle. The battery compartment 102 houses the at least one battery pack securely and efficiently, ensuring both stability and ease of access for swapping, maintenance, charging, or replacement purposes. Fabrication of the battery compartment 102 involves materials that offer durability, while also considering weight optimization to maintain the overall efficiency of the electric vehicle. The dimensions of the battery compartment 102 match the specific size and shape of the battery packs, thereby ensuring a snug fit. Additionally, thermal management features are incorporated into the battery compartment 102 to regulate the temperature of the battery packs, thus enhancing performance and longevity. The battery compartment 102 includes mechanisms for electrical connectivity that facilitate seamless integration with the power system of electric vehicle. The aforesaid mechanisms provide reliable and efficient energy transfer from the battery packs to various components (e.g., motor, lighting arrangement etc.) of electric vehicle. Furthermore, the battery compartment 102 incorporates safety features to protect against hazards such as short circuits, overheating, or physical damage. The safety features maintain the overall integrity and safety of the electric vehicle.
In an embodiment, the pivot mechanism 104 pivotally connects the battery compartment 102, to a chassis member of the electric vehicle. The pivot mechanism 104 provides a pivotal movement of the battery compartment 102 relative to the chassis member, facilitating an effective and efficient means of accessing the at least one battery pack housed within the battery compartment 102. The design of pivot mechanism 104 allows the battery compartment 102 to move between a closed position, where the at least one battery pack is securely housed within the electric vehicle, and an open position, where the at least one battery pack is accessible for swapping, maintenance, charging, or replacement. In the closed position, pivot mechanism 104 provides a secure and stable alignment of the battery compartment 102 with the chassis member, thereby maintaining the structural integrity and operational safety of the electric vehicle. In the open position, pivot mechanism 104 allows the battery compartment 102 to be moved away from the chassis member to an extent sufficient to permit user access to the at least one battery pack. Additionally, the pivot mechanism 104 facilitates a smooth and controlled movement of the battery compartment 102, thereby preventing abrupt or uncontrolled movements that could lead to damage to the at least one battery pack or the electric vehicle.
In an embodiment, the pivot mechanism 104 can incorporate various types of pivoting mechanisms, each suited to specific operational requirements and design constraints of the battery system in electric vehicle. Among the pivoting mechanisms, a hinge pivot mechanism can offer effective rotational movement for applications where controlled opening and closing are essential. The hinge type of pivot is particularly advantageous in systems where the battery pack needs to be accessed regularly for maintenance or replacement, ensuring a straightforward and reliable operation.
In an embodiment, another option for pivot mechanism 104 is the ball-and-socket joint, which provides greater flexibility by allowing rotation in multiple directions. Such type of pivot is especially useful where the battery pack might need to be manipulated or oriented in different positions during the mounting or dismounting process. The multi-axis rotation capability can enhance the ease of handling large or awkwardly shaped battery packs.
In another embodiment, swivel joints can be used as pivot mechanism 104. The swivel joint can be particularly beneficial where the battery pack needs to pivot out from a confined space or where angular alignment during installation is critical. Alternatively, cantilever pivot mechanism (which supports a structure at one end while allowing the other end to move), can be employed in EV where the battery pack must extend out from the chassis member for easier access or where space constraints within the vehicle dictate a specific movement pattern.
In an embodiment, universal joints or sliding pivot mechanisms might be considered for pivot mechanism 104. Universal joints accommodate angular misalignments and are useful in scenarios where the battery pack needs to be rotated or tilted in various planes during installation or removal. Sliding pivots, offering linear or curvilinear movement, can be advantageous in automated systems where precision alignment is critical.
In an embodiment, the arrangement 100 comprises at least one support member 106, to facilitate a soft opening and closing of the battery compartment 102 via the pivot mechanism 104. The support member 106 provides controlled movement and stability to the battery compartment 102 during the operation. Through the inclusion of the support member 106, the opening and closing actions of the battery compartment 102 are smoothed and safeguarded against abrupt movements, thereby enhancing the safety and longevity of the mechanism. The support member 106 operates in conjunction with the pivot mechanism 104, ensuring that during the pivotal movement of the battery compartment 102 can be in steady and gentle motion. The support member 106 can significantly reduce the risk of mechanical stress (on pivot mechanism 104, chassis, battery compartment 102 and the like) and damage to the battery packs housed within the battery compartment 102. The support member 106 can apply a counterbalancing force during the operation of the battery compartment 102, thereby enabling a user-friendly experience in accessing the battery packs. Furthermore, the support member 106 is constructed from materials chosen for the durability and strength, ensuring that the support member 106 remains functional over a prolonged period and under various operational conditions. The support member 106 (e.g., air struts and hydraulics) can provide a damping effect, which enable smooth and gradual opening and closing of the battery compartment to reduce/eliminate jerky or abrupt movements that could potentially jostle or damage the battery or vehicle components. The controlled motion battery compartment 102 is crucial while dealing with heavy battery packs, where uncontrolled movements can lead to mechanical stresses and potential damage. Further, the support member 106 can be associated with a safety feature that can in that lock the compartment in an open position, preventing accidental closures that could harm operators/user or damage the battery. The support member 106 can enable to achieve mechanization of opening process to reduce physical strain on operator/user, this can particularly be beneficial in scenarios where battery swaps are frequent and manual opening could lead to fatigue or injury. Moreover, the controlled opening mechanism (through support member 106) allow opening of the battery compartment just enough to access the battery pack, without requiring extra space for manual handling.
In an embodiment, the opening provided by the support member 106 may be essential for providing controlled and effortless access to the battery packs housed within the battery compartment 102. The support member 106 allows soft opening of the battery compartment 102 up to at a predefined angle (with respect to chassis), ensuring that the battery compartment 102 does not open beyond a certain limit. Such feature of the support member 106 safeguards against overextension or damage to the battery compartment 102 and the associated mechanisms. Furthermore, the predefined angle is carefully determined to provide optimal accessibility to the battery packs while maintaining the structural integrity and stability of the arrangement 100.
In an embodiment, the arrangement 100 may comprise a door specifically for securing the battery compartment 102 with chassis. The door provides both access and protection to the battery compartment 102 against external elements and unauthorized access. Moreover, the door aligns with the contours of the electric vehicle, ensuring that the aesthetic appeal of the vehicle is maintained while providing the necessary functional attributes. The incorporation of a locking mechanism in the door can also prevent unintended movement of battery compartment 102. Additionally, the door may comprise a sealing arrangement to prevent the ingress of dust, moisture, and other contaminants into the battery compartment 102, thereby ensuring the longevity and optimal performance of the battery packs contained therein. The door may facilitate ease of operation, allowing users to effortlessly access the battery compartment 102 for maintenance or replacement of the battery packs. Furthermore, the door takes into consideration the safety requirements associated with handling and storing battery packs, incorporating features that mitigate risks such as accidental opening or release of the battery packs during transit. The door can act as sealing member to seal each battery pack in a specific position and also prevents any axial movement within the battery compartment 102. Thus, the door can enable stable positioning of each battery pack to maintain a stable and efficient electrical connection, which is essential for the reliable operation of the vehicle. The stable positioning also prevents electrical short circuits, which might occur due to loose connection of battery pack with respective electric terminal.
In an embodiment, the door may be mounted on the chassis member, facilitating access to the battery compartment 102. The door, pivotal in nature, is attached in a manner allowing for the opening and closing of the battery compartment 102, thereby enabling efficient access to the battery pack. The mounting of door on the chassis member can be executed through a series of hinges or similar pivotal connectors, which are placed to provide stability and ease of operation. In the closed position, the door is securely locked to the chassis member, ensuring the safety and security of the battery pack within the battery compartment 102. The latch mechanism, integral to the design of the door, is crafted to provide secure closure while allowing for quick release when access to the battery pack is required. Optionally, dampers or shock absorbers can be integrated with door to aid controlled and smooth operation, minimizing the risk of damage or undue stress to the battery pack during the opening and closing of the battery compartment 102.
In an embodiment, the arrangement 100 comprises a locking member for controlling the movement of the battery compartment 102. The locking member (e.g., cam lock, pneumatic lock, latch mechanism, etc.) selectively enables or disables the pivot movement of the battery compartment 102 relative to the at least one support member 106. In operation, when activation of the locking member occurs, the locking member engages with the battery compartment 102, thereby allowing controlled pivot movement. Such pivotal motion is essential for the accessibility of the battery packs housed within the battery compartment 102, facilitating ease in maintenance activities such as replacement or charging. Conversely, when deactivation of the locking member occurs, the locking member effectively restricts any pivot movement of the battery compartment 102, thereby ensuring the secure and stable positioning of the battery compartment 102 in relation to the chassis member. The locking member provides a balance between ease of access to the battery packs and the security needed during the operation of vehicle. By securing the battery compartment in an open position, the locking member can prevent accidental closures, reducing the risk of injury or damage to the battery and vehicle during swapping/maintenance. Similarly, the locking member can prevent opening of the battery compartment 102.
In an embodiment, the pivot mechanism 104 may permit the battery compartment 102 to rotate relative to the chassis member of the electric vehicle. The rotation facilitated by the pivot mechanism 104 is characterized by the ability to occur in at least one direction selected from a group consisting of a horizontal direction, a vertical direction, and an oblique direction. The rotation of the battery compartment 102 is smooth and controlled, thereby enabling the user to access the battery pack or packs housed within the battery compartment 102 with relative ease. Furthermore, the implementation of the pivot mechanism 104 allows for an enhanced degree of flexibility in the positioning and orientation of the battery compartment 102. The pivot mechanism 104, through the design, effectively contributes to the efficient utilization of space within the electric vehicle, and also aids in reducing the physical effort required to access the battery compartment 102.
In an embodiment, the battery compartment 102 may engage with at least one battery pack of an electric vehicle. The engagement is facilitated through the incorporation of a plurality of rollers, positioned within the battery compartment 102. Each roller is designed to engage against at least one side of the at least one battery pack. The rollers are constructed to provide smooth and controlled movement of the battery pack into and out of the battery compartment 102, thereby ensuring an efficient and secure mounting and dismounting process. The rollers within the battery compartment 102 can enable even weight distribution during the mounting and dismounting operations. The even distribution of weight aids in reducing the mechanical stress on the battery pack/battery compartment 102, thereby enhancing the longevity and operational efficiency. Furthermore, the rollers are designed to minimize friction, which contributes to a reduction in the effort required for the insertion and removal of the battery pack from the battery compartment 102. Additionally, the rollers are fabricated from materials that provide durability and resistance to wear and tear, thus ensuring the long-term reliability of the battery compartment 102.
In an embodiment, the least one support member 106 may comprise a hydraulic damper to control the opening and closing of the battery compartment 102. The hydraulic damper modulates the movement of the battery compartment 102, thereby enabling a smooth and controlled access to the battery pack. The hydraulic damper in the at least one support member 106 operates by utilizing hydraulic fluid to resist rapid movements, thus ensuring that the opening and closing of the battery compartment 102 occurs in a gradual and controlled manner. The hydraulic damper prevents abrupt movements that could damage the battery pack or the electric vehicle. The incorporation of the hydraulic damper into the at least one support member 106 enhances the safety and reliability of the arrangement 100. The hydraulic damper provides a means to control the kinetic energy during the opening and closing of the battery compartment 102, effectively reducing the risk of uncontrolled or accidental movements. Additionally, the hydraulic damper ensures that the battery compartment 102 can be securely held in both the open and closed positions, providing stability and security for the battery pack during maintenance or replacement procedures.
Optionally, the arrangement 100 comprises a U-shaped enclosure that partially or fully encloses the hydraulic damper. For example, the U-shaped enclosure is disposed such that edges of the U-shaped enclosure are disposed parallely/co-planarly with a front face of the battery compartment 102 and a curved portion of the U-shaped enclosure is disposed behind a rear face of the battery compartment 102. Further, the hydraulic damper is arranged between the rear face of the battery compartment 102 and the curved portion of the U-shaped enclosure. Consequently, such disposing of the hydraulic damper within the U-shaped enclosure enables to protect the hydraulic damper and/or the battery compartment 102 from shocks transmitted to the chassis during operation of the electric vehicle while also providing support to the battery compartment 102 during pivoting of the battery compartment 102.
In an embodiment, the at least one support member 106 may comprise a spring mechanism to exert controlled force, thereby facilitating the opening and closing of the battery compartment 102. The incorporation of the spring in the at least one support member 106 enables a smooth transition of the battery pack into and out of the battery compartment 102, enhancing the overall efficiency of the mounting and dismounting process. The spring in the at least one support member 106 provides optimal resistance and support, ensuring that the battery pack is securely held within the confines of the battery compartment 102 when in the closed position, and allows for ease of access when in the open position.
In an embodiment, the at least one support member 106 may comprise a pneumatic cylinder, in which provided controlled opening and closing of the battery compartment 102. The pneumatic cylinder facilitates the automated manipulation of the battery compartment 102, ensuring a smooth and efficient operation. The pneumatic cylinder exerts precise force, thereby enabling the controlled and gradual opening and subsequent closing of the battery compartment 102. The controlled movement maintains the integrity and safety of the battery compartment 102 during the movement thereof. The incorporation of the pneumatic cylinder in the at least one support member 106 provides smooth opening and closing of battery compartment 102.
In an embodiment, the battery compartment 102 may comprise a guide arrangement specifically designed to facilitate the precise alignment of at least one battery pack. The guide arrangement enables seamless engagement and disengagement of the battery packs with respect to the electric vehicle. The guide arrangement may guide the battery packs into a secure and optimal position within the battery compartment 102. The guide arrangement includes various structural elements such as rails, grooves, or channels, which are positioned within the battery compartment 102. The aforesaid elements align with corresponding features on the battery packs, ensuring a guided and controlled insertion or removal process. The guide arrangement minimizes the risk of misalignment, thereby reducing damage to the battery packs and the battery compartment 102 during the mounting and dismounting processes.
In an embodiment, the pivot mechanism 104 may be motorized, thereby enabling automated opening and closing of the battery compartment 102. Motorization of the pivot mechanism 104 is particularly beneficial in electric vehicle, where manual operation of the battery compartment 102 could be cumbersome. The motorized pivot mechanism 104 facilitates ease of access to the battery compartment 102, thus enhancing the efficiency of battery pack exchange processes. Furthermore, the integration of motorization into the pivot mechanism 104 provides a consistent and reliable operation, regardless of the physical capabilities of the operator.
In an embodiment, the at least one support member 106 may incorporate an electronic control system to synchronize with the onboard computer of the electric vehicle, ensuring seamless operational integration. The onboard computer can adjust the speed of opening and closing battery compartment 102.
FIG. 2 (FIG. 2A to FIG. 2B) illustrates distinct positions of the battery compartment with respect to chassis member for mounting and dismounting of battery pack, in accordance with the embodiments of the present disclosure. FIG. 2A depicts the battery compartment 102 in a conventional, operational position where the battery pack is secured and mounted, showcasing the integration of battery compartment 102 into the frame of vehicle in a manner that is consistent with standard battery placements in electric vehicles. The position represents the state during normal vehicle operation. Transitioning to FIG. 2B, the battery compartment 102 is illustrated in a pivoted position, having been tilted by the predefined angle away from the initial, conventional position. The tilting mechanism (that is pivot mechanism 104) allows access to the battery pack, thereby reducing the physical exertion typically required for such operations and minimizing the time and effort involved in the maintenance or replacement of the battery pack. The approach streamlines the process of battery interchangeability and enhances the user experience by mitigating the traditionally labor-intensive process of battery maintenance in electric vehicles.
