Description:A POWER UNIT EJECTION SYSTEM AND METHOD THEREOF
TECHNICAL FIELD
[0001] The present subject matter generally relates to system and method for a power unit ejection system. More particularly, but not exclusively to a 5 system and method of power unit ejection systems for vehicles.
BACKGROUND
[0002] The increasing reliance on power units and battery packs in modern vehicles has ushered in a new era of efficient and sustainable transportation. 10 However, as the complexity of these power units has grown, so have the challenges associated with their management and safety. Several critical issues confront power unit systems, threatening both their optimal performance and the safety of vehicle operation. Overcharging, overheating, moisture infiltration, cell imbalances, and short circuits are among the 15 prominent concerns that demand immediate attention. Left unaddressed, these issues not only compromise the longevity and efficiency of the power unit but also pose significant safety risks to both the vehicle and its occupants.
[0003] Existing power unit ejection systems often fall short in providing a comprehensive solution to these challenges. Detection mechanisms may be 20 rudimentary, lacking the ability to categorize faults into distinct states and prioritize them based on potential risks.
[0004] Moreover, the absence of user-friendly guidance exacerbates the problem, leaving vehicle owners and operators uncertain about how to address identified faults effectively. In scenarios where the power unit faces 25 issues such as overcharging, overheating, moisture infiltration, cell imbalances, or short circuits, the typical user is often inadequately informed and lacks the necessary knowledge to navigate these situations safely. The nature of these potential problems and their consequences may not be readily apparent to users, rendering them ill-equipped to make informed decisions or 30 take appropriate actions during the battery ejection and charging processes.
3
[0005] This lack of knowledge leaves users vulnerable, as they may not recognize the severity of the identified problems or understand the potential risks associated with them. Without proper guidance, users may inadvertently exacerbate the existing issues, compromise their safety, and inflict further damage on the power unit. Additionally, the absence of clear instructions can 5 lead to an increased likelihood of mishandling the power unit, inadvertently causing harm or irreparable damage.
[0006] When a user attempts to eject the power unit or battery pack for charging, the existing lack of a comprehensive safety mechanism leaves them vulnerable to various potential hazards. Overcharging may lead to irreversible 10 damage to the battery cells, posing safety risks and diminishing the overall lifespan of the power unit. Overheating can result in thermal runaway, a phenomenon associated with catastrophic consequences, potentially causing harm to the user and permanent damage to the power unit.
[0007] Moisture infiltration, often unnoticed, can lead to corrosion and short 15 circuits within the power unit. Cell imbalances, if unaddressed, may further exacerbate safety concerns during the charging process, potentially leading to an increased risk of fire or electric shock. Short circuits, if present, can escalate quickly, causing damage to the power unit and posing an immediate threat to the user. 20
[0008] The absence of a systematic approach to identify and categorize these potential risks during the battery ejection process jeopardizes user safety and the longevity of the power unit. Without a comprehensive solution, users remain susceptible to injuries, and power units may incur irreversible damage without avenues for repair. Therefore, there exists a need for mechanism that 25 addresses these critical issues comprehensively. Such a system should not only detect these potential hazards but also categorize and prioritize them, providing user-friendly instructions to mitigate risks and safeguard both the user and the power unit from harm and irreparable damage.
[0009] The development of a comprehensive mechanism for power unit 30 ejection and removal from the vehicle is crucial for enhancing the safety,
4
reliability, and user experience in the management of advanced power units within vehicles. [00010] Thus, there is a need in the art for a method and a system for a power unit ejection system for a vehicle and method thereof which addresses at least the aforementioned problems and other problems of known art. 5
[00011] Further limitations and disadvantages of conventional and traditional approaches will become apparent to one of skill in the art, through comparison of described systems with some aspects of the present disclosure, as set forth in the remainder of the present application and with reference to the drawings. 10

[00032] As per an aspect of the present subject matter, the overcharged state, the overheated state, the moisture-affected state is categorized into the normal fault. Whereas, the cell imbalance state, the short circuit state is categorized 5 into the critical fault. In the present subject matter, the intention is to categorize low priority faults in normal fault, that the user can easily fix on their own with the help of the guidelines being displayed by the system. The system aims to allow for the addition of more fault states in the future, ensuring adaptability to emerging battery technologies. This distinction 10 allows for targeted responses to different fault scenarios, optimizing system performance and safety.
[00033] As per an aspect of the present subject matter, the controller is configured to store at least one of the determination of the plurality of fault conditions, the state of the power unit, and the categorization of the state of 15 the power unit into one of the plurality of distinct categories in at least one of a memory storage and a remote server. This feature enhances data management, facilitating subsequent analysis, remote diagnostics, and potential system improvements. The user and the service provider is also able to understand the various issues going on in the battery over a period of time, 20 therefore, being able to identify any recurring issues or potential hazards.
[00034] As per an aspect of the present subject matter, the plurality of actions is performed by the controller comprises of enables the locking mechanism, disables the locking mechanism, reports the state of the power unit to a service provider, display a set of instructions on a display device based on the state 25 of the power unit. The set of instructions facilitates user guidance for overcomes the plurality of fault conditions, and restore the power unit to the normal state. This multifaceted approach ensures that users receive clear guidance in various fault scenarios, reducing the risk of accidents and system damage. Potential future enhancements may involve incorporating more 30 intuitive user interfaces or seamless integration with smart vehicle systems.
10
[00035] As per an aspect of the present subject matter, the controller is configured to selectively perform the plurality of actions based on the state of the power unit and the categorization of the state of the power unit into the plurality of distinct categories. The ability of the controller to selectively perform actions based on the power unit's state and categorized fault 5 conditions ensures a nuanced and efficient system operation tailored to specific situations, optimizing resource usage and responsiveness. As technology advances, incorporating machine learning algorithms for more intelligent decision-making based on historical data and user preferences could further enhance this feature. 10

Further, the controller is configured to update the category of the state of the power unit to the critical fault when the count of the state of the power unit is more than a threshold number of times. The check on the count of the power unit's state and 15 updating the category during repeated critical faults adds an additional layer of security and adaptability. By dynamically adjusting the threshold based on real-world usage patterns, the system can optimize its performance and user experience over time. This feature ensures that the system remains adaptive to evolving conditions and user behaviours. 20
[00037] As per an aspect of the present subject matter, the controller is configured to perform a fault correction sequence to update the state of the power unit from the overcharged state, the overheated state, the moisture-affected state, the cell imbalance state, the short circuit state to the normal state. The fault correction sequence, integral to the power unit ejection system 25 disclosed herein, operates as a diagnostic and remedial protocol. Initiating with a fault detection phase, it scrutinizes various potential anomalies within the power unit, covering the conditions like overcharging, overheating, moisture ingress, cell imbalances, and short circuits. Upon pinpointing the specific fault, the sequence orchestrates a series of precise corrective 30 manoeuvres tailored to rectify the identified issue. These manoeuvres may include system reinitialization procedures, parameter adjustments, or
11
analogous interventions aimed at restoring the power unit to its normal state. The fault correction sequence ensures a proactive response to evolving fault scenarios, contributing to the reliability, and longevity of the power unit ejection system. [00038] As per an aspect of the present subject matter, the controller is 5 configured to enable the locking mechanism when the categorization of the state of the power unit is at least one of the normal and the critical fault. Further, the controller is configured to disable the locking mechanism when the state of the power unit is the normal state. The control of the locking mechanism, enabling it during both normal and critical faults and disabling it 10 when the power unit is in a normal state, contributes significantly to system security. This feature prevents unauthorized removal during fault conditions, reducing the risk of accidents or damage. Potential developments may involve authentication systems for enhanced security measures.
[00039] The present invention provides a method of operation of a power unit 15 ejection system for a vehicle. The method comprises of steps of the controller receives an input by a sensor. The controller receives a plurality of parameters associated with a power unit. It then determines a plurality of fault conditions of the power unit based on the plurality of parameters associated with the power unit once the sensor receives the input. Further, the controller 20 determines a state of the power unit based on the determination of the plurality of fault conditions. It categorizes the state of the power unit into one of a plurality of distinct categories. The controller performs a plurality of actions based on at least the state of the power unit and the plurality of distinct categories associated with the state of the power unit. These plurality of 25 actions comprises of operation of a locking mechanism. The operation of the locking mechanism is based on the state of the power unit to prevent removal of the power unit during failure.
[00040] As per an aspect of the present subject matter, the method further comprises of steps of the controller storing at least one of the determination 30 of the plurality of fault conditions, the state of the power unit, and the
12
categorization of the state of the power unit into the plurality of distinct categories in at least one of a memory storage and a remote server. The controller checks a count of the state of the power unit and the categorization of the state of the power unit. The controller updates the category of the state of the power unit to the critical fault when the count of the categorization of 5 the state of the power unit is normal fault is more than a threshold number of times. Then the controller selectively performs the plurality of actions based on the state of the power unit and the categorization of the state of the power unit into the plurality of distinct categories. The controller displays a set of instructions on a display device based on the state of the power unit. These 10 set of instructions facilitates user guidance for overcomes the plurality of fault conditions, and restore the power unit to the normal state. The controller reports the state of the power unit to a service provider. [00041] As per an aspect of the present subject matter, the method further comprises of steps of the controller performs a fault correction sequence to 15 update the state of the power unit from the overcharged state, the overheated state, the moisture-affected state, the cell imbalance state, the short circuit state to the normal state. The controller enables the locking mechanism when the categorization of the state of the power unit is at least one of the normal fault and the critical fault. The controller disables the locking mechanism 20 when the state of the power unit is the normal state.
[00042] The present subject matter is described using a power unit ejection system which is used in a vehicle, whereas the claimed subject matter can be used in any other type of application employing above-mentioned power unit ejection system, with required changes and without deviating from the scope 25 of invention. Further, it is intended that the disclosure and examples given herein be considered as exemplary only.
[00043] The terms “an embodiment”, “embodiment”, “embodiments”, “the embodiment”, “the embodiments”, “one or more embodiments”, “some embodiments”, and “one embodiment” mean “one or more (but not all) 30 embodiments of the invention(s)” unless expressly specified otherwise. The

The embodiments of the present invention will now be described in 5 detail with reference to the power unit ejection system with the accompanying drawings. However, the present invention is not limited to the present embodiments. The present subject matter is further described with reference to accompanying figures. It should be noted that the description and figures merely illustrate principles of the present subject matter. Various 10 arrangements may be devised that, although not explicitly described or shown herein, encompass the principles of the present subject matter. Moreover, all statements herein reciting principles, aspects, and examples of the present subject matter, as well as specific examples thereof, are intended to encompass equivalents thereof. 15
[00045] Figure 1 exemplarily illustrates a block diagram in accordance with an embodiment of the present disclosure. The controller (102) is communicable connected to the power unit (104) and receives a plurality of parameters from the power unit (104) to check for the plurality of fault conditions. The sensor (108) is configured to send input responses to the 20 controller (102) based on which the controller (102) initiates the power unit ejection system. The controller (102) is also enabled to control the locking mechanism (106). The locking mechanism may be a physical or digital system that restricts the removal of the power unit. The purpose of this mechanism is to enhance safety by preventing users from disconnecting the 25 power unit when it is in an abnormal or potentially hazardous state. The locking mechanism may be a physical lock that physically secures the power unit within its compartment, making it inaccessible for removal. Alternatively, it can involve a digital lock controlled by the system's controller, which restricts the release of any locking mechanisms until 30 specific safety criteria are met. For instance, when the power unit is in the critical fault, indicating a severe issue like a short circuit, the locking
14
mechanism may engage automatically to prevent user intervention. This ensures that only authorized personnel, such as service providers or technicians, can access the power unit for inspection or maintenance.
The locking mechanism serves as a safeguard, ensuring that the power unit is handled with care and only disconnected under safe conditions, minimizing 5 the risk of accidents or damage to the power unit. [00046] Figure 2a and Figure 2b exemplarily illustrates a flowchart in accordance with an embodiment of the present disclosure.
[00047] The method initiates the process at step 201, the steps of the following method are performed by the controller (102). The method moves 10 to 202, here, the controller (102) receives the input given to the sensor (108) by the user of the power unit ejection system. This initiates the method for the check and correction of the faults in the power unit (104).
[00048] At step 203, the controller (102) receives a plurality of parameters associated with a power unit (104). These parameters comprise of a 15 temperature of the power unit (104), a state of charge of the power unit (104), a charging status of the power unit (104), a battery level of the power unit (104). After receiving the plurality of parameters, the controller (102) checks for plurality of fault conditions comprising the temperature of the power unit (104) being above a threshold temperature, a presence of moisture content in 20 the power unit (104) being above a threshold content, a parameter for cell imbalance being above a threshold imbalance, a leakage current being above a threshold leakage.
[00049] At step 204, it checks for whether the temperature of the power unit (104) is less than the threshold temperature OR the presence of moisture 25 content in the power unit (104) is less than the threshold content. If it is less, then the power unit (104) is deemed to be a in a normal and safe state where the controller checks for more conditions to ensure there is safety hazard at step 206.
15
[00050] If the criteria is not met, the method moves to step 205. Where, if the temperature is high or the moisture content is more than permissible, the controller (102) identifies that the power unit (104) is in the overcharged state, the overheated state, the moisture-affected state which is categorized into the normal fault. 5
[00051] Further, to ensure that there is not critical fault that is causing these abnormal conditions, step 206 checks whether a parameter for cell imbalance is less than a threshold imbalance OR if there is a leakage current more than the threshold leakage. If there are no faults related to cell imbalance and leakage current (which is indicative of a short circuit), and the power unit is 10 merely overcharged, overheated or maybe there is more moisture than permissible, then the power unit (104) is deemed to considered in a normal fault at step 206a, which is low on priority. Normal faults may be caused due to reasons like long period of usages, and the like.
[00052] However, if there are faults related to cell imbalance and leakage 15 current (which is indicative of a short circuit), the power unit is deemed to be in the cell imbalance state, or the short circuit state and is categorized into the critical fault at step 207. Due to its critical state, the same is reported to a service provider.
[00053] If all the checks made at step 204 and at 206 are held to be true and 20 the power unit is in one of the normal faults or the critical faults, then the controller (102) stores at least one of the determination of the plurality of fault conditions, the state of the power unit (104), and the categorization of the state of the power unit (104) into the plurality of distinct categories in at least one of a memory storage and a remote server. This aids in checking the 25 previous history of faults and to make a detailed analysis on potential hazards.
[00054] If all checks made at step 204 and at 206 are held to be false, then power unit is in normal and safe state. If the power unit is in normal state, the method moves to step 213, and the controller (102) is disabled the locking mechanism (106) permitting the user to remove the power unit (104) from the 30 vehicle.
16
[00055] After storing the data in the server/memory storage, the method moves to step 210 in case of normal/critical fault.
[00056] At step 210, check a count of the categorization of the state of the power unit (104). At step 211, if the count of normal fault is more than a threshold number of times, for example, the power unit has been overheating 5 for more than 3 times, the fault is then updated to critical, due to its recurrence being deemed as a potential hazard.
[00057] The controller (102) updates the category of the state of the power unit (104) to critical fault at step 212, and reports it to the service provider for further checks at step 213. 10
[00058] If the count of normal fault is less than a threshold number of times, the method moves to step 214, where the controller (102) enables the locking mechanism (106) when the categorization of the state of the power unit (104) being at least one of the normal fault and the critical fault.
[00059] At step 215, the controller (102) performs a fault correction sequence 15 to update the state of the power unit (104) from the overcharged state, the overheated state, the moisture-affected state, the cell imbalance state, the short circuit state to the normal state.
[00060] At step 216, the controller (102) displays a set of instructions on a display device to facilitate user guidance to restore the power unit (104) to 20 the normal state. The set of instructions guide the user to perform certain steps that can bring the power unit back to its normal state.
[00061] At step 217, the controller (102) check if the fault correction sequence and the user instructions have succeeded in bringing the power unit back to its normal state. If yes, the controller (102) disables the locking 25 mechanism (106) to enable the user to remove the power unit (104).
[00062] If the power unit (104) has not returned to its normal state, the method moves to step 210, and checks the count for normal faults, in case the controller (102) and the user instructions are unable to bring the power unit
17
(104)back to its normal state. The locking mechanism (106) is enabled andcan only be removed by authorized users such as the service providers.[00063] In an embodiment, the vehicle has one or more power units. The power unit ejection system and the locking mechanism (106) is individually enabled for each of the one or more power units (104) thereby ensuring that 5 the user may be able to recharge at least one of the one or more power units to operate the vehicle.
[00064] Following is a working example to explain the above method.
[00065] In the first scenario, let us consider that the power unit is in a normal state. Therefore: First, the user initiates ejection by pressing the button/switch 10 on the dashboard of the vehicle. The dashboard can be a front portion of any vehicle where the user generally has a user interface disposed to interact with the vehicle. The sensor receives the input, prompting the controller to check conditions:
1.Temperature threshold: Below 40°C.15
2.Charge status: Between 20% and 80%.
3.Battery level: Above 20%.
4.Moisture content: Below 5%.
[00066] All conditions are met; therefore, the controller (102) categorizes as the power unit (104) as “normal state” and unlocks the locking mechanism. 20 The locking mechanism disengages, allowing the user to safely remove the power unit.
[00067] In a second scenario, abnormal conditions are detected. The controller (102) detects high temperature (e.g., 50°C), categorizing as the state of the power unit as "Overheated." The locking mechanism (106) 25 remains engaged, and the infotainment system displays a message. The user is advised to wait until temperature drops below the threshold. The controller (102)continuously monitors temperature, updating the user on theinfotainment system. Once the temperature of the power unit (104) is below
18
40°C, the controller categorizes as “normal state” and unlocks the mechanism. [00068] In a third scenario, a critical fault is found. The controller (102) detects a short circuit, categorizing as "Critical Fault." The locking mechanism stays engaged; infotainment instructs user to contact service 5 provider. The diagnostic data transmitted to a remote server for analysis. The service provider accesses data, provides guidance remotely, or schedules an inspection. The controller in all these scenarios also performs, Fault Correction Sequence is performed by the controller (102), the controller (102) triggers fault correction for an overcharged state. The diagnostic steps 10 performed by the controller (102) could be, charging current threshold: Above 10A. Then, disabling the charging until current is below 10A. The controller (102) may also update power unit firmware to prevent future overcharging. The controller then stores diagnostic data in memory for reference. In these scenarios, the controller also tracks frequency of abnormal 15 conditions. If overcharging persists, the controller (102) initiates corrective measures. The firmware of the power unit (102) is updated remotely. The user receives notifications to visit a service centre for further inspection.
[00069] A person with ordinary skills in the art will appreciate that the systems, modules, and sub-modules have been illustrated and explained to 20 serve as examples and should not be considered limiting in any manner. It will be further appreciated that the variants of the above disclosed system elements, modules, and other features and functions, or alternatives thereof, may be combined to create other different systems or applications.
[00070] The present invention also aims to enhance user interaction with a 25 switch on the dashboard, ensuring intuitive control and accessibility for power unit ejection, prioritizing user convenience and safety. The present invention also aims to monitor crucial parameters like temperature and charge status, optimizing power unit health and extending battery life by preventing potential damage from abnormal conditions. 30
19
