[0020] FTG. 1 depicts a battery swapping network. The battery swapping network 100, as depicted, comprises one or more battery packs 101 located in a vehicle 102, and one or more battery charging and swapping stations 103. The vehicle 102 may comprise one or more battery packs 101, wherein one of the battery packs 101 act as a master battery pack 101, and the other battery packs 101 act as slave battery pack(s).

[0021] In an embodiment herein, the battery pack 101 can be a swappable battery pack. The battery pack 101 may comprise a controller 101 A, a geo-location module 101B, a tilt sensor 101C, an accelerometer 101D, a gyro-sensor 101E, a Thermal Interface Unit (TIU) 101F, a Battery Management System (BMS) 101G, one or more temperature sensors 101H, a voltage monitoring sensor 1011, a proximity sensor 101 J, a deformation detection sensor 101 K, one or more user interfaces 101L, one or more communication modules 101M, and a memory 101N. In an embodiment herein, the controller 101A, and the BMS 101G can be integrated into a single unit. In an embodiment herein, the controller 101A, and the BMS 101G can be separate modules. The vehicle 102 can further comprise a motor controller 102 A, and a communication module 102B.

[0022] The geo-location module 10 IB can determine the current location of the battery pack 101 in terms of latitude, and longitude. In an embodiment herein, the geo-location module 101B can continuously determine the location of the battery pack 101 continuously, when the battery pack 101 is present in the vehicle 102. The geo-location module 101B can use at least one of Global Positioning System (GPS), GAGAN, GLONASS, Galileo, sell triangulation, and so on, for determining the location of the battery pack 101. The geo-location module 101B can communicate the determined location to the controller 101A. The geo-location module 101B can store the determined location in a suitable location, such as the memory 101N, the Cloud, one or more battery charging and swapping stations, and so on. The geo-location module 101B can be used by the controller 101A for determining information such as, but not limited to, region-wide battery count, enforcing anti-theft measures, and so on. In an embodiment herein, the data from multiple geo-location modules 101 B from multiple battery packs 101 can be sent to a cloud. Based on the data from the geo-location module 101B, the cloud and / or an authorized person can determine the number of battery packs 101 being used in a specific region. Based on the data from the geo-location module 101B, the cloud and / or an authorized person can determine if the battery pack 101 is authorized to be used in a region where the battery pack 101 is currently being used, and on determining that the battery pack 101 is not authorized to be used in the regionwhere the battery pack 101 is currently being used, the controller 101A can receive an alert from the cloud, and disable the battery pack 101 (i.e., the battery pack 101 docs not provide an output power).

[0023] The tilt sensor 101C can determine the angle and / or slope of the battery pack 101. The accelerometer 101D can determine the acceleration of motion of the battery pack 101 . The gyro-sensor 101 E can determine the rotation angle of the battery pack 101 per unit of time. The inputs as determined by the tilt sensor 101C, the accelerometer 101D, and the gyro-sensor 101E can be communicated continuously to the controller 101. Based on the inputs from the tilt sensor 101C, the accelerometer 101D, and the gyro-sensor 101E, the controller 101A can determine the orientation of the battery. The proximity sensor 101.1, and the deformation detection sensor 101K can determine the deformation level of the battery pack 101 .

[0024] The controller 101 A can compare the data (which can be real-time) from sensors (i.e., the tilt sensor 101C, the accelerometer 101D, the gyro-sensor 101E, the proximity sensor 101 J, and the deformation detection sensor 101K) to pre-loaded data present in the memory 101N. The deformation detection sensor 101K can monitor changes in the physical characteristics of the battery pack 101. In an embodiment herein, the deformation detection sensor 101K can use one or more strain gauges strategically placed within the battery enclosure monitor changes in the physical characteristics of the battery pack 101. In an embodiment herein, the deformation detection sensor 101K can use one or more pressure sensors strategically placed within the battery enclosure monitor changes in the physical characteristics of the battery pack 101. In an embodiment herein, the deformation detection sensor 101K can use one or more strain gauges and one or more pressure sensors strategically placed within the battery enclosure monitor changes in the physical characteristics of the battery pack 101 . Consider an example scenario where the battery pack experiences deformation (which can be due to external impact and / or internal issues), the deformation detection sensor 101K can detect changes in strain or pressure, and are provided to the controller 101 A.

[0025] If the data from the sensors is within a pre-defined range of the pre- loaded data, the controller 101A does not initiate any further action. If the data from the sensors is not within a pre-defined range of the pre-loaded data, the controller 101A can assume that the battery pack 101 is falling (and may subsequently have undergone damage and / or deformation) and can provide an alert to a user of the battery pack 101 (i.e., the operator of the vehicle) using the one or more user interfaces 101L. In an example herein, if the data from the sensors is not within a pre-defined range of the pre-loaded data, the controller 101 A can provide an alert to the user of the battery pack 101 using an audio alert. In an example herein, if the data from the sensors is not within a pre-defined range of the pre-loaded data, the controller 101 A can provide an alert to the user of the battery pack 101 using a visual alert (such as one or more lights). In an example herein, if the data from the sensors is not within a pre-defined range of the pre-loaded data, the controller 101 A can provide an alert to the user of the battery pack 101 using the audio alert, and the visual alert (such as one or more lights). On receiving the alert, the user can perform one or more actions, such as, but not limited to, stop operating the vehicle, isolating, and quarantining the battery pack 101, and so on.

[0026] In an embodiment herein, the controller 101 can isolate and repair damaged battery packs based on the detected physical impact and deformation data. The batter}' pack 101 can have one or more quarantine codes for critical issues, which can be stored in the memory 10 IN. Consider an example scenario, wherein the batterj' pack 101 raises a quarantine code due to physical damage. On the battery pack 101 being inserted into a batter}' charging and swapping station, the battery charging and swapping station can read the quarantine code and will disable the battery pack 101 from being swapped, till the battery pack 101 has been resolved / repaired.

[0027] On detecting that the battery pack 101 is undergoing a drop (i.e., an abrupt increase in the acceleration of the battery pack 101, the battery pack 101 rotating, and so on), the controller 101A can trigger a fault. The controller 101A can further store related data in a suitable location, such as, but not limited to, the memory 101N, the Cloud, one or more battery charging and swapping stations, andso on. The stored data can be used for identifying the physical damage associated with the battery pack 101 , and thus help in isolating and repairing that battery pack 101.

[0028] The controller 101 A can communicate with other battery packs present in the vehicle 100 using the communication module 101M, and collect information from the other battery packs present in the vehicle 100, such as, but not limited to, the State of Charge (SoC) of the battery packs 101, battery current, and so on. Using the collected information, the controller 101A can identify imbalance(s) (if any) during driving and improve battery efficiency and mileage by modulating a power map (which can be stored in the memory 101N). The power map can be developed based on the type of vehicle where the battery pack 101 is being used, nature of usage of similar vehicle, and so on. The controller 101 A can store the collected information in a suitable location, such as, but not limited to, the memory 101N, the Cloud, one or more battery charging and swapping stations, and so on.

[0029] The one or more temperature sensors 101H can measure the temperature at one or more points within the battery pack 101, and communicate the measured temperature continuously to the controller 101A. The controller 101A can compare the measured temperature to a pre-defined temperature threshold (which can be stored in the memory 101N). If the measured temperature is greater than the pre-defined temperature threshold, the controller 101 can use the TIU 101F to control the temperature of the battery pack 101 using one or more heating and cooling elements (not shown). The controller 101 A can store the measured temperature in a suitable location, such as, but not limited to, the memory 101N, the Cloud, one or more battery charging and swapping stations, and so on, wherein the controller 101A and / or any other entity (such as the Cloud) can identify issues related to charging and discharging by analyzing the measured temperature.

[0030] The controller 101 A can monitor and record the reasons for battery discharge / charge stoppage, and shutdown of the battery pack 101 in a suitable location, such as, but not limited to, the memory 101N, the Cloud, one or more battery charging and swapping stations, and so on, wherein the controller 101Aand / or any other entity (such as the Cloud) can analyze and resolve issues causing the stoppage.

[0031] The controller 101 A can identify and track the features of the battery pack 101 using the pre-configured configuration and firmware, which has been preconfigured in the memory 10 IN.

[0032] The controller 101 A can monitor data related to the state of charge (SOC) and state of health (SOH) of the battery pack 101. The controller 101A can store the monitored data in a suitable location, such as, but not limited to, the memory 101N, the Cloud, one or more battery charging and swapping stations, and so on, wherein the controller 101A and / or any other entity (such as the Cloud) can develop insights into the energy level and health of the battery pack 101 .

[0033] The controller 101A can track and record the ampere-hours (Ahr) and kilowatt-hours (kWhr) consumed by the battery pack 101 , which can be used by the controller 101A and / or any other entity (such as the Cloud) for maintaining accurate energy billing and monitoring.

[0034] The confroller 101 A can measure and monitor the voltages and temperatures of individual battery cells present in the battery pack 101. The controller 101A can use this information to identify cell-level abnormalities, optimize charging and discharging patterns, and improve battery efficiency.

[0035] The controller 101A can identify and record the status of battery cell balancing. The controller 101A can use data related to battery cell balancing to analyze the behavior and effectiveness of cell balancing mechanisms.

[0036] The controller 101A can monitor the temperatures at the vehicle docking bay (i.c., the bay in the vehicle into which the battery pack is inserted) to identify any issues related to the connection between the battery pack 101 and the vehicle.

[0037] The controller 101 A can record the status of digital inputs and outputs that are controlled by the BMS 101G. The controller 101A can use the recorded status for problem analysis and troubleshooting of the battery pack 101.

[0038] The controller 101A can collect and store additional parameters such as vehicle speed and odometer readings to compute the distance travelled by the vehicle.

[0039] The controller 101 A can capture and store information related to the motor controller 102A, which is necessary for analyzing and improving the vehicle's performance.

[0040] The controller 101 A can be implemented by analog and / or digital circuits such as logic gates, integrated circuits, microprocessors, microcontrollers, memory circuits, passive electronic components, active electronic components, optical components, hardwired circuits and the like, and may optionally be driven by firmware.

[0041] The controller 101A may include one or a plurality of processors. The one or the plurality of processors may be a general-purpose processor, such as a central processing unit (CPU), an application processor (AP), or the like, a graphics-only processing unit such as a graphics processing unit (GPU), a visual processing unit (VPU), and / or an Al-dedicated processor such as a neural processing unit (NPU). The controller 101A may include multiple cores and is configured to execute the instructions stored in the memory 101N.

[0042] Further, the controller 101A can be configured to execute instructions stored in the memory 101N and to perform various processes. The communication module(s) 101M is configured for communicating internally between internal hardware components and with external devices via one or more networks. The memory 101N can comprise data from the geo-location module 101B, the tilt sensor 101C, the accelerometer 101D, the gyro-sensor 101E, and other sensors, modules, present in the battery pack 101 , other battery packs present in the vehicle, vehicle systems / modules, and so on. The memory 101N can be pre- loaded with orientation and physical change data of the battery pack. The memory 101N can comprise data related to falls (if any). The memory 101N can comprise configuration information (such as, but not limited to, firmware version, and so on). The memory 101N also stores instructions to be executed by the controller 101A. The memory 101N may include non-volatile storage elements. Examples of suchnon-volatile storage elements may include magnetic hard discs, optical discs, floppy discs, flash memories, or forms of electrically programmable memories (EPROM) or electrically erasable and programmable (EEPROM) memories. In addition, the memory 101N may, in some examples, be considered a non-transitory storage medium. The term “non-transitory” may indicate that the storage medium is not embodied in a carrier wave or a propagated signal. However, the term “non- transitory” should not be interpreted that the memory 101N is non-movable. In certain examples, a non-transitory storage medium may store data that can, over time, change (e.g., in Random Access Memory (RAM) or cache).

[0043] In an embodiment, the communication modulc(s) 101M include an electronic circuit specific to a standard that enables wired or wireless communication. The communication module(s) 10 IM are configured to communicate internally between internal hardware components of the battery pack 101 and with external devices via one or more networks.
