[0002] This section is intended to introduce the reader to various aspects of art that may be related to various aspects of the present disclosure, which are described below. This disclosure is believed to be helpful in providing the reader with background information to facilitate a better understanding of the various aspects of the present disclosure. Accordingly, it should be understood that these statements are to be read in this light, and not just as admissions of prior art.
[0003] The need for special conservation and protection system for a lithium-ion battery and a charger has increased due to the widespread use of these batteries, particularly, for electric vehicles (EV). Since the development in EV charging infrastructure is in a very nascent stage, there is a huge problem in providing any possible solution till now for protection of electric vehicles (EV) charger from theft and to increase the life cycle of lithium-ion battery. Also, a battery management system (BMS) has been proposed in various prior art, but the same is not solving the problem of controlling overcharging or over discharging of lithium-ion batteries.

[0006] In another embodiment of the present disclosure, a method is provided for increasing the lifecycle of a battery of an electric vehicle, comprising monitoring, by the Battery Management System (BMS), the overcharging voltage and over-discharging voltage of the battery; disconnecting the charger from the battery by the Battery Management System (BMS) when an overcharging voltage exceeds a threshold value; and connecting the charger with the battery when an over-discharging voltage goes below the threshold value, thereby conserving the lifecycle of the charger and the battery.

DETAILED DESCRIPTION OF THE DISCLOSURE
[0013] For the purpose of promoting an understanding of the principles of the disclosure, reference will now be made to the embodiment illustrated in the drawings and specific language will be used to describe the same. It will nevertheless be understood that no limitation of the scope of the disclosure is thereby intended, such alterations and further modifications in the illustrated system, and such further applications of the principles of the disclosure as illustrated therein being contemplated as would normally occur to one skilled in the art to which the disclosure relates.
[0014] It will be understood by those skilled in the art that the foregoing general description and the following detailed description are exemplary and explanatory of the disclosure and are not intended to be restrictive thereof. Throughout the patent specification, a convention employed is that in the appended drawings, like numerals denote like components.
[0015] Reference throughout this specification to “an embodiment”, “another embodiment”, “an implementation”, “another implementation” or similar language means that a particular feature, structure, or characteristic described in connection with the embodiment is included in at least one embodiment of the present disclosure. Thus, appearances of the phrase “in an embodiment”, “in another embodiment”, “in one implementation”, “in another implementation”, and similar language throughout this specification may, but do not necessarily, all refer to the same embodiment.
[0016] The terms “comprises”, “comprising”, or any other variations thereof, are intended to cover a non-exclusive inclusion, such that a process or method that comprises a list of steps does not include only those steps but may include other steps not expressly listed or inherent to such process or method. Similarly, one or more devices or sub-systems or elements or structures proceeded by “comprises... a” does not, without more constraints, preclude the existence of other devices or other sub-systems or other elements or other structures or additional devices or additional sub-systems or additional elements or additional structures.
[0017] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this disclosure belongs. The apparatus, system, and examples provided herein are illustrative only and not intended to be limiting.
[0018] The terms “a” and “an” herein do not denote a limitation of quantity, but rather denote the presence of at least one of the referenced items. Further, the term sterile barrier and sterile adapter denotes the same meaning and may be used interchangeably throughout the description.
[0019] Referring to figure 1, a system (100) is provided for conserving the lifecycle of a battery (104) and protection of a charger (101) of an electric vehicle which comprises a charger (101) for connected to the battery (104), a Global Positioning System (GPS) (105) installed inside the charger (101), an IoT device (102) communicatively connected to the Global Positioning System (GPS) (105) and is configured to receive notification from the Global Positioning System (GPS) (105) about theft of the charger (101). The Global Positioning System (GPS) gets activated to send a notification to the IoT device when a power supply to the charger is not detected/is cut-off. Further, a Battery Management System (BMS) (103) is wired to the battery (104) and is configured to operatively communicate with IoT device (102) and the charger (101), wherein the Battery Management System (BMS) (103) disconnects the charger (101) from the battery (104) when an overcharging voltage exceeds a threshold value and connects the charger (101) with the battery (104) when an over-discharging voltage goes below the threshold value, which results in conserving the lifecycle of the charger and the battery.

[0020] Referring to figure 2, when a power supply to the charger (101) is not detected, it suggests that the charger (101) is being cut off/stolen from the setup. As a result, the Global Positioning System (GPS) (105) sends distress signal/notification to the IoT device (102), held by the user. The charger (101) has an inbuilt Global Positioning System (GPS) (105) which tracks the stolen charger in real time and displays the same on the screen of the IoT device (102) so that the user can be informed about the whereabout of the stolen charger.

[0021] Referring to figure 3, a method (200) is provided for increasing the lifecycle of the battery of an electric vehicle, comprising monitoring, by the Battery Management System (BMS) (103), the voltage of the battery during charging cycle; disconnecting the charger (101), by the Battery Management System (BMS) (103) when the charging voltage of the battery crosses the threshold value, to prevent overcharging.
[0022] Referring to figure 4, a method is provided for increasing the lifecycle of the battery of an electric vehicle, comprising: monitoring, by the Battery Management System (BMS) (103), the discharging voltage of the battery; connecting the charger (101), by the Battery Management System (BMS) (103) when the voltage of the battery falls below the threshold value, to prevent over discharging. Here the term “threshold value” means the rated upper and lower limit of the voltage of the battery.

[0023] Thus, the above embodiments of the present disclosure ensure that theft of the EV charger may be tracked in a fast and efficient manner. Also, the overcharging and over discharging can be averted by use of a Battery Management System (BMS) which ensures to conserve the lifecycle of the battery used.
[0024] Further, the disclosure also provides a method for external communication through UART/IR or by any other means to check the various parameters of the system, automatically to confirm its proper functioning.
[0025] Furthermore, the disclosure also informs the end user, digitally about the warranty status of the charger when it is at the fag end of its warranty period.
[0026] Benefits, other advantages, and solutions to problems have been described above with regard to specific embodiments. However, the benefits, advantages, solutions to problems, and any component(s) that may cause any benefit, advantage, or solution to occur or become more pronounced are not to be construed as a critical, required, or essential feature or component of any or all the claims.
[0027] While specific language has been used to describe the disclosure, any limitations arising on account of the same are not intended. As would be apparent to a person in the art, various working modifications may be made to the apparatus in order to implement the inventive concept as taught herein. ,CLAIMS:WE CLAIM:
