TECHNICAL FIELD
Generally, the present disclosure relates to a battery pack. Particularly, the present disclosure relates to a system and a method for tracking swappable powerpacks for electric vehicles.
BACKGROUND
Electric vehicles (EVs) have emerged as a sustainable and energy-efficient alternative to internal combustion engine vehicles, driven by advancements in electric drivetrain systems and the growing demand for cleaner transportation solutions. A fundamental component of EV operation is the energy storage system, typically implemented via rechargeable lithium-ion battery packs. In various EV architectures, swappable batteries have gained importance, especially in applications involving light electric vehicles, two-wheelers, or commercial fleets, swappable batteries. The swappable battery configurations rely on modular battery units housed within dedicated battery containers integrated into the vehicle chassis. The battery container provides mechanical support, electrical connectivity, and thermal management during vehicular operation.
The conventional electric vehicles designed with swappable batteries primarily focus on power delivery, mechanical coupling, and high-level charge management. Specifically, the existing technologies related to battery tracking and management in electric vehicles focus on fixed batteries with integrated Battery Management Systems (BMS) that monitor parameters such as voltage, temperature, and state of charge within the vehicle. Further, the conventional telematics platforms collect and transmit vehicle-level data to cloud-based servers for fleet monitoring. Furthermore, RFID-based battery identification systems and QR-code tagging provide basic inventory tracking. The inventory tracking utilizes radio-frequency identification tags embedded in or attached to swappable batteries, thereby enabling identification through short-range wireless communication with compatible readers. Each RFID tag used for inventory tracking stores a unique identifier, allowing the system to verify the presence, type, or ownership of a battery during check-in, check-out, or at fixed checkpoints within a facility. Furthermore, advanced fleet systems implement GPS modules within vehicles or charging infrastructure.
However, there are certain problems associated with the existing or above-mentioned mechanism for tracking a swappable battery of an electric vehicle. For instance, the absence of precise battery detachment detection, independent battery-level telemetry, and secure data synchronization introduces critical gaps in reliability, traceability, and operational safety of the battery pack. Further, the loss of real-time tracking after battery removal presents challenges in theft prevention, unauthorized usage detection, and post-detachment analytics. Moreover, the RFID tracking lacks real-time telemetry, operational data capture, environmental monitoring capabilities, and continuous condition-based insights. The absence of sensor integration or remote communication limits RFID-based solutions to localized inventory applications and lacks dynamic field-level battery tracking. Furthermore, the above-mentioned mechanism lacks in providing robust solutions for managing energy-efficient telemetry activation or maintaining secure data continuity across multiple operational states of the battery.
Therefore, there exists a need for a mechanism for tracking the swappable battery of an electric vehicle that is secure, interoperable, and an automated alternative.

In an embodiment, the at least one decoupling detection sensor 116 is configured to detect a variation in at least one physical parameter associated with the engagement state between the at least one swappable battery 102 and the at least one battery container 106. The monitored parameter includes, but is not limited to, mechanical pressure, electrical contact continuity, magnetic field alignment, or positional displacement. Specifically, the decoupling detection sensor 116 detects changes in the selected parameter indicative of a shift from a coupled to a decoupled condition. Further, a deviation beyond a predefined threshold triggers a signal, indicating a detachment event. Furthermore, the detection mechanism utilizes a calibrated baseline reference for the engaged state and applies differential sensing to identify any deviation from the coupled configuration. The technique of detection involves periodic sampling of the physical parameter and comparison with the reference dataset stored in the sensor’s onboard memory. Furthermore, noise reduction filters and signal averaging algorithms refine the acquired data to eliminate environmental or operational noise. The decoupling detection sensor 116 distinguishes true engagement changes from transient disturbances through state validation logic, which requires persistence of parameter variation over a defined duration before confirming a detachment event. With confirmation, the sensor issues an output signal to the battery telematic device 112, enabling synchronized system response. Moreover, the signal activates auxiliary processes, including power transition, sensor activation, and data transmission, to ensure continuity of battery tracking. Consequently, the detection detachment through variation in a physical parameter provides precise event identification without reliance on manual input or external systems.

In an embodiment, the at least one decoupling detection sensor 116 is configured to filter detected variations, based on differentiating a true detachment event from a transient disturbance. The decoupling detection sensor 116 performs continuous signal analysis to differentiate true detachment events from transient disturbances by employing a filtering mechanism. Specifically, the filtering involves capturing real-time variations in the monitored physical parameter, such as, but not limited to, contact force, alignment displacement, or electrical continuity, and applying temporal and amplitude-based criteria to each data point. The decoupling detection sensor 116 executes a validation sequence that evaluates signal persistence, rate of change, and deviation from baseline thresholds. Further, the signals that meet predefined duration and magnitude conditions are classified as valid detachment triggers. Furthermore, the transient fluctuations caused by vibrations, minor shocks, or electrical noise are rejected during the process. The procedure incorporates a digital filtering algorithm integrated into the firmware of the decoupling detection sensor 116. The algorithm utilizes techniques such as, but not limited to, moving average smoothing, peak suppression, and anomaly scoring to refine raw input data. Furthermore, the decoupling detection sensor 116 maintains a dynamic buffer of recent signal states and applies weighted analysis to identify trends consistent with mechanical decoupling. Moreover, the events that fail to meet the validation criteria are automatically discarded, and the system maintains the engaged-state status. Moreover, valid detachment events result in the generation of a signal pulse delivered to the battery telematic device 112 for initiating post-detachment operations, including activation of tracking sensors and commencement of autonomous telemetry. Consequently, filtering detected variations to reject transient disturbances enables enhanced accuracy and reliability in battery detachment detection.

In an embodiment, the decoupling detection sensor 116 employs adaptive thresholding algorithms configured to dynamically adjust sensitivity based on filtered variations and transient disturbances. The decoupling detection sensor 116 utilizes adaptive thresholding algorithms to dynamically adjust sensitivity in response to varying environmental and operational conditions. Specifically, the decoupling detection sensor 116 captures real-time input data related to physical parameters such as pressure, displacement, or alignment, and processes the data through an internal control logic that adjusts detection thresholds based on historical signal patterns. The adaptive thresholding algorithm evaluates signal stability, noise characteristics, and event frequency to calibrate trigger points in real time. Further, the system 100 maintains operational responsiveness by modifying threshold values to suit transient disturbances, mechanical wear, or environmental changes, ensuring consistent performance across diverse deployment scenarios. The procedure incorporates feedback loops within the detection firmware to update threshold parameters continuously based on filtered variations. Furthermore, the weighted scoring mechanism assigns significance levels to recent input events, allowing the system to increase or decrease sensitivity dynamically. In case the frequency of false-positive detections increases, the algorithm raises the detection threshold to reduce susceptibility to spurious signals. Conversely, in case genuine detachment events are detected with low signal strength, the algorithm lowers the threshold to preserve detection integrity. Moreover, the decoupling detection sensor 116 stores trend data in non-volatile memory, supporting long-term calibration and adaptation to changes in mechanical engagement over repeated usage cycles. The adaptive algorithm operates independently on the decoupling detection sensor 116 hardware, maintaining low-latency decision-making without dependence on external processors. Consequently, the adaptive thresholding provides improved detection accuracy through context-aware calibration of sensitivity levels. Additionally, advantages of the adaptive thresholding algorithms include enhanced discrimination between actual detachment events and non-critical signal disturbances, prolonged decoupling detection sensor 116 effectiveness under variable conditions, and reduced need for manual recalibration.

The decoupling detection sensor 116 remains in a monitoring state during engagement of the swappable battery 102 with the battery container 106 and transitions to a signaling state upon confirmed detachment. Specifically, the decoupling detection sensor 116 continuously samples the defined physical parameter and compares the physical parameter against adaptive or fixed thresholds. As the parameter exceeds the defined limits for a validated duration, the decoupling detection sensor 116 authorizes the detachment event. Further, following the confirmation, the decoupling detection sensor 116 generates a detachment signal in the form of an electrical output pulse or digital state change. The signal is routed through a dedicated line or communication bus directly interfaced with the battery telematic device 112. The above-mentioned procedure ensures deterministic timing between physical detachment and signal delivery. Moreover, a hardware interrupt or polling-based trigger captures the signal at the battery telematic device 112 input, initiating a transition sequence that includes wake-up from standby mode, power path activation, and initiation of sensor subsystems. The detachment signal acts as the primary trigger for transitioning the battery telematic device 112 into autonomous operation. Furthermore, signal integrity is maintained through shielding and error-checking logic to prevent false activation or missed events.

Specifically, the signal generation occurs immediately after confirmation of a valid detachment event via analysis of physical parameter variations. The decoupling detection sensor 116 firmware formats the output into a digital interrupt protocol compliant with the battery telematic device 112 input configurations. The interrupt signal utilizes edge or level-triggered logic to ensure prompt detection by the microcontroller embedded in the battery telematic device 112. Further, the signal propagation follows a hardware-routed trace or wired bus designed for minimal latency and high signal fidelity. The procedure of transmission includes signal debouncing and shielding to eliminate noise interference during high-frequency transitions. The battery telematic device 112 maintains an interrupt handler in the firmware, constantly monitoring the designated input pin for changes initiated by the detachment signal. Upon receiving the interrupt, the device bypasses standard polling or wake-cycle delays and transitions immediately to the tracking mode. Furthermore, the interrupt-driven approach reduces power consumption by eliminating the need for continuous active monitoring. Consequently, using a digital interrupt signal for detachment notification enables immediate, reliable system activation synchronized with mechanical events. Additionally, advantages of the digital interrupt signal include deterministic system behavior, minimized reaction time, and precise correlation between detachment and telemetry initiation.

The communication interface 118 between the vehicle telematic device 108 and the battery telematic device 112 incorporates a key exchange protocol configured to dynamically establish encryption keys. During initial synchronization or pairing, each telematic device generates a temporary key pair using a cryptographic algorithm such as Elliptic Curve Diffie-Hellman (ECDH). Specifically, a secure handshake procedure transmits public keys over the communication interface 118 with private keys remaining stored within secure memory. The shared secret derived from the exchanged public keys forms the basis for session-specific symmetric encryption keys used to protect operational data during transfer. Further, the protocol includes mutual authentication and certificate validation to verify device identities before any data exchange. The authentication includes periodic regeneration of cryptographic material based on session triggers or elapsed time intervals. The vehicle telematic device 108 initiates the key exchange during system boot, synchronization cycles, or upon detection of a new swappable battery 102. Furthermore, the battery telematic device 112 responds with the credentials and public key, enabling secure derivation of encryption keys on both ends. The encryption of operational data occurs in real time using authenticated encryption modes such as AES-GCM, which ensures confidentiality, integrity, and resistance against replay attacks. The communication interface 118 handles key negotiation, message framing, encryption, and validation within a defined session, monitored by an internal security controller. Consequently, employing a key exchange protocol in the communication interface 118 offers secure, dynamic establishment of encryption keys for protected data transmission. Additionally, advantages of the key exchange protocol include resistance to interception, prevention of unauthorized access, and cryptographic assurance of operational data integrity between telematic devices.

In an embodiment, the communication interface 118 is configured to apply a periodic renewal of encryption keys based on session events, and elapsed time during the operational data transfer between the at least one vehicle telematic device 108 and the at least one battery telematic device 112. The communication channel between the vehicle telematic device 108 and the battery telematic device 112 implements periodic renewal of encryption keys based on session events and elapsed time during operational data transfer. Specifically, a session manager embedded within the communication module 118 monitors for each synchronization session, tracks elapsed time, and records key usage metrics. with reaching a predefined time threshold or after completion of a specific number of data transactions, the session manager initiates a key renewal sequence. Further, the process involves executing a new key exchange protocol similar to the initial handshake, generating fresh cryptographic keys without disrupting active communication. The session remains authenticated throughout the renewal using temporary session tokens and integrity checks to prevent unauthorized interruption. The procedure integrates session-based renewal logic into both telematic devices, with synchronized timers and counters ensuring consistent execution across endpoints. Furthermore, key lifetimes are strictly defined, and cryptographic policies enforce regeneration intervals to minimize exposure windows. During the operational data transfer, the system 100 fragments data into encrypted packets tagged with metadata including key version identifiers and timestamps. With key renewal, both devices discard the old keys, generate new key material through a secure exchange, and resume encryption using the updated keys. Moreover, attempting to access data with outdated keys results in immediate rejection by the decryption logic, preserving data confidentiality and communication authenticity. Consequently, the periodic encryption key renewal during operational data transfer provides continuous protection against long-term key compromise, replay attacks, and cryptographic exhaustion. Additionally, advantages include sustained data confidentiality over extended communication sessions, reduced vulnerability to intrusion attempts, and enhanced resilience of the telemetry system under adversarial conditions. The key renewal mechanism ensures secure and reliable telemetry synchronization throughout the swappable battery 102 lifecycle, supports high-frequency data exchange, and aligns with modern security standards in electric vehicle 104 battery management networks.
