Description

[0001] MESSAGING-BASED ACCESS AND CONTROL SYSTEM AND METHOD FOR MANAGING ELECTRIC VEHICLE (EV) CHARGING

[0002] FIELD

[0003] The present disclosure relates to electric vehicle charging. More particularly, focused on messaging-based access and control systems for electric vehicle (EV) charging.

[0004] DEFINITION

[0005] As used in the present disclosure, the following terms are generally intended to have the meaning as set forth below, except to the extent that the context in which they are used indicates otherwise.

[0006] Electric Vehicle (EV): The term “Electric Vehicle (EV)” refers to a type of vehicle that is powered by one or more electric motors using energy stored in rechargeable batteries, rather than relying on an internal combustion engine that uses fossil fuels.

[0007] QR Codes: The term “QR (Quick Response)” refers to codes that are two-dimensional barcodes that store information, such as URLs, text, or data, which can be easily scanned using a smartphone or a QR code reader to quickly access the encoded content.

[0008] The above definitions are in addition to those expressed in the art.

[0009] BACKGROUND

[0010] The background information herein below relates to the present disclosure but is not necessarily prior art.

[0011] The existing EV charging systems in India are primarily divided between expensive EV chargers with Open Charge Point Protocol (OCPP) used in public spaces and basic home charging sockets with limited safety features.

[0012] In the Indian market, there are two primary types of EV chargers: EV chargers and Normal Home charging sockets. EV chargers use the Open Charge Point Protocol (OCPP) to interact with a vehicle management system, providing information to users through an Electric Vehicle mobile app. These chargers, often installed in public spaces like parking lots, hotels, and malls, are relatively expensive due to their advanced features. On the other hand, Normal Home charging sockets are 230V AC supply sockets that are configured with onboard chargers ofEVs. They include basic safety features such as short circuit and earth fault protection, but lack the functionalities found in the more sophisticated chargers.

[0013] Therefore, there is a need for a Messaging-based access and control system for electric vehicle (EV) charging and method for managing electric vehicle (EV) chargingthat alleviates the aforementioned drawbacks.

[0014] OBJECTS

[0015] Some of the objects of the present disclosure, which at least one embodiment herein satisfies, are as follows:

[0016] It is an object of the present disclosure to ameliorate one or more problems of the prior art or to at least provide a useful alternative.

[0017] An object of the present disclosure is to provide a messaging-based access and control system (100) and method for managing electric vehicle (EV) charging

[0018] Another object of the present disclosure is to provide a Messaging-based system that simplifies the control of multiple EV charging points with cost-effective monitoring and automatic power cutoff.

[0019] Still another object of the present disclosure is to provide a Messaging-based system that enables accurate automated billing for EV charging, enhancing transparency and convenience.

[0020] Yet another object of the present disclosure is to provide a Messaging-based system that enables seamless EV charging management using QR codes.

[0021] Still another object of the present disclosure is to provide a Messaging-based system that enables secure, efficient, and user-friendly EV charging management.

[0022] Other objects and advantages of the present disclosure will be more apparent from the following description when read in conjunction with the accompanying figures, which are not intended to limit the scope of the present disclosure.

[0023] SUMMARY

[0024] The present disclosure envisages a messaging-based system and method for managing electric vehicle charging without requiring users to install a dedicated EV charging mobile application.Instead, the charging process is initiated through a messaging platform, making the experience simpler and more accessible for users in shared charging environments.

[0025] In this system, an EV charging socket is provided with a QR code that contains a unique identifier for that specific charging point. When a user wants to charge an electric vehicle, the user scans the QR code using a messaging-based mobile interface, which sends the charger identifier along with the user’s mobile number for authentication.

[0026] A backend server validates the received information by checking the user’s credentials against stored authorization data. Once the user is successfully verified, the system sends control instructions to enable the charging socket and start the charging process. This allows remote and secure control of charging access.

[0027] During the charging session, the system continuously monitors and records energy consumption through an integrated power metering function. This consumption data is transmitted to the backend for tracking, reporting, and displaying real-time status of the charging session.

[0028] The present disclosure also includes an automatic switching feature that turns OFF the charging socket when charging is completed or when the load drops below a predefined threshold. This prevents unnecessary power draw in idle conditions, conserves energy, and frees the charging point for use by other users.

[0029] The system further provides real-time notifications to the user through the messaging platform, such as charging start confirmation, ongoing status updates, error alerts, and charging completion messages. In addition, a web-based portal is provided for operators to manage multiple chargers, monitor charging sessions, allocate charging access, track availability, and generate usage reports.

[0030] Overall, the present disclosure offers a secure, efficient, and cost-effective EV charging management solution using QR-based authorization and messaging-based communication, particularly suitable for fleet operations and shared charging locations such as apartments and commercial premises.

[0051] DETAILED DESCRIPTION

[0052] Embodiments, of the present disclosure, will now be described with reference to the accompanying drawing.

[0053] Embodiments are provided so as to thoroughly and fully convey the scope of the present disclosure to the person skilled in the art. Numerous details are set forth, relating to specific components, and methods, to provide a complete understanding of embodiments of the present disclosure. It will be apparent to the person skilled in the art that the details provided in the embodiments should not be construed to limit the scope of the present disclosure. In some embodiments, well-known processes, well-known apparatus structures, and well-known techniques are not described in detail.

[0054] The terminology used, in the present disclosure, is only for the purpose of explaining a particular embodiment and such terminology shall not be considered to limit the scope of the present disclosure. As used in the present disclosure, the forms "a,” "an," and "the" may be intended to include the plural forms as well, unless the context clearly suggests otherwise. The terms "comprises," "comprising," “including,” and “having,” are open ended transitional phrases and therefore specify the presence of stated features, elements, modules, units and / or components, but do not forbid the presence or addition of one or more other features, elements, components, and / or groups thereof.

[0055] When an element is referred to as being “engaged to,” "connected to," or "coupled to" another element, it may be directly engaged, connected, or coupled to the other element. As used herein, the term "and / or" includes any and all combinations of one or more of the associated listed elements.

[0056] The rapid growth of electric vehicle adoption has created a strong need for reliable and scalable charging infrastructure, particularly in shared spaces such as apartment complexes, workplaces, commercial parking areas, and fleet depots. In these environments, multiple usersoften compete for limited charging resources, making efficient access control and usage management critical.

[0057] Conventional EV charging systems typically rely on dedicated mobile applications, RFID cards, or proprietary access devices for user authentication and charger operation. These approaches increase system complexity, require users to install and maintain specific applications, and add operational and maintenance costs for service providers. Additionally, onboarding new users and managing access credentials can be cumbersome in large or frequently changing user groups.

[0058] Another challenge with existing charging solutions is the lack of efficient mechanisms to prevent energy wastage after charging completion. Many chargers continue to draw idle power when a vehicle is fully charged, reducing energy efficiency and blocking charger availability for other users. Limited real-time monitoring and delayed user notifications further impact charger utilization.

[0059] Accordingly, there exists a need for an EV charging management solution that simplifies user access, enables secure remote control, supports real-time monitoring and automated energysaving features, and can be easily deployed and scaled without dependence on dedicated charging applications or additional physical authentication hardware.

[0060] Therefore, the present disclosure envisages a Messaging-Based Access and Control System and method for managing electric vehicle (EV) charging (hereinafter referred to as system (100), method (200)). The present disclosure is explained with reference to the Figure la to Figure 5B

[0061] Figures la, lb, 1c, and Id describe the flow chart of Messaging Based Access And Control System for Electric Vehicle (EV) Charging, in accordance with an embodiment of the present disclosure. The quick response (QR) code (106b) code-based authorization system can be integrated with an EV charging socket (106) for controlling the switching of Electric Vehicle (EV) chargers. The Messaging-Based Access and Control System (100) leverages mobile communication through a Messaging platform to validate user credentials and manage the charging process remotely.

[0062] The messaging-based access and control system (100) for electric vehicle charging comprises an EV charging socket (106), an Internet of Things (loT) based switch (106a) integrated with the EV charging socket (106), a quick response (QR) code (106b) associated with the EVcharging socket (106), a messaging mobile application (110), an EV entity database server (112), a home cloud server (104), a messaging cloud server (108), and an EV charging web portal (102).

[0063] The EV charging socket (106) is a physical charging interface configured for electrical coupling with an electric vehicle to support charging through a compatible connector arrangement. In one implementation, the EV charging socket (106) is installed at a charging station located in a fleet hub, residential apartment complex, workplace parking, or a shared EV charging location. The EV charging socket (106) is configured to deliver controlled charging power to the connected EV and to capture charging session parameters including charging start time, charging stop time, operational status, and load characteristics. The EV charging socket (106) may further include hardware electronics to support device connectivity, operational monitoring, and exchange of control messages with the home cloud server (104), thereby enabling remote charging control.

[0064] In one embodiment, the EV charging socket (106) includes an Internet of Things (loT) based switch (106a) configured to control the power delivery to the connected electric vehicle. The loT based switch (106a) is integrated within the EV charging socket (106) and acts as an electronically controllable switching element. In one configuration, the loT based switch (106a) comprises a relay or contactor capable of switching mains power for EV charging, and further includes safety circuitry such as overload protection and short-circuit protection to prevent electrical hazards. The loT based switch (106a) is configured to switch between an ON state to allow power flow to the EV charging socket (106) and an OFF state to interrupt the power delivery, thereby enabling remote start and stop of charging sessions.

[0065] In a further embodiment, a power metering unit is integrated within the loT based switch (106a) of the EV charging socket (106) to monitor and record energy consumption during charging. The power metering unit is configured to detect electrical parameters including voltage, current, and real-time power consumption, and compute energy delivered to the EV during the charging session. In one implementation, the power metering unit maintains cumulative energy consumption values in kilowatt-hours and records time-stamped charging data, thereby enabling charging session auditability. The power metering unit is further configured to transmit measured consumption data to the EV entity database server (112) through the home cloud server (104), allowing centralized recording, reporting, and analysis of energy usage.The QR code (106b) is associated with the EV charging socket (106) and is configured to facilitate user access and authorization without requiring physical keys or dedicated authentication devices. The QR code (106b) encapsulates a unique device identifier (DID) linked to the EV charging socket (106), wherein the DID serves as a unique identity of the charger for mapping the user request to the correct charging point. The QR code (106b) is placed on the EV charging socket (106) or near the charging station such that it can be scanned conveniently by a driver at the location. The QR code (106b) thereby enables quick charger identification, reduces manual input errors, and supports seamless user onboarding by providing a direct digital entry point for charging authorization.

[0066] The messaging mobile application (110) is configured to operate on a user’s mobile device as the primary user interface for initiating and controlling EV charging operations. The messaging mobile application (110) is configured to scan the QR code (106b) to initiate an authorization process for enabling charging, and upon scanning, the messaging mobile application (110) is triggered to send the DID and the user’s mobile number for validation. In one embodiment, the messaging mobile application (110) is implemented through a messaging platform-based interface, allowing users to interact with the system (100) using existing mobile communication applications. The messaging mobile application (110) thereby eliminates the need for a dedicated EV charging application installation, enabling ease of access for drivers and reducing friction in shared charging locations.

[0067] The messaging mobile application (110) is further configured to receive charging-related messages and notifications generated by the system (100). In one implementation, the messaging mobile application (110) provides real-time notifications to the user, including charging initiation confirmation, charging status updates, fault alerts, and charging completion notification. The messaging mobile application (110) may also prompt the user for confirmation before performing an operational action, such as switching ON the EV charging socket (106) when the charger is OFF, or switching OFF the EV charging socket (106) when charging is already active. Accordingly, the messaging mobile application (110) provides a simplified and interactive workflow for the user to securely control charging operations through messaging-based communication.

[0068] The EV entity database server (112) is configured to function as an authentication, authorization, and data management backend for the system (100). The EV entity database server (112) stores and maintains data received from the messaging mobile application (110)and the QR code (106b), including the DID, user mobile number, authorization records, and charging session information. In one embodiment, the EV entity database server (112) validates the received DID and user mobile number against pre-stored authorized user credentials associated with an EV entity such as a fleet operator, apartment owner, or charging service provider. The EV entity database server (112) thereby ensures that only authorized users are permitted to switch ON or switch OFF the EV charging socket (106).

[0069] In one embodiment, upon successful validation of user credentials, the EV entity database server (112) transmits authorization data and operational requests for charging control. The authorization data may include permission status, user identity confirmation, charger identity confirmation, and switching eligibility conditions. The operational requests may include control messages such as a request to switch ON the EV charging socket (106) to initiate charging or a request to switch OFF the EV charging socket (106) to terminate charging. In one configuration, the EV entity database server (112) generates a secure token as part of the authorization response, wherein the token is used to ensure that switching commands are executed only for validated users and valid sessions.

[0070] The home cloud server (104) is communicatively connected with the EV entity database server (112) and the EV charging socket (106) and is configured to trigger operational commands on the EV charging socket (106). The home cloud server (104) receives the authorization data and the operational requests from the EV entity database server (112), determines operational feasibility such as device connectivity status, and executes switching actions on the EV charging socket (106). In one embodiment, the home cloud server (104) acts as a device-control gateway that communicates with the loT based switch (106a) of the EV charging socket (106) using suitable networking protocols, enabling remote and real-time switching operations.

[0071] In one implementation, the home cloud server (104) is configured to transmit ON and OFF control commands to the loT based switch (106a) for initiating and terminating charging sessions. When an ON command is executed, the loT based switch (106a) enables power delivery to the EV charging socket (106) and charging begins. When an OFF command is executed, the loT based switch (106a) disables power delivery and charging is terminated. The home cloud server (104) may additionally maintain device status information such as online / offline availability of the EV charging socket (106), and if the charging socket (106) is offline, the home cloud server (104) prevents switching to ensure safe operation and notifies the user of the connectivity issue via the messaging mobile application (110).The power metering unit integrated within the EV charging socket (106) is configured to transmit energy consumption data through the home cloud server (104) to the EV entity database server (112). The home cloud server (104) receives such data from the charging socket (106), formats the data into structured charging session records, and forwards the same to the EV entity database server (112) for storage and reporting. The EV entity database server (112) then uses this data to generate real-time status, consumption analytics, and usage reporting for operators and users. This architecture ensures that power monitoring remains linked to switching operations and user authorization, enabling reliable charging session management.

[0072] The messaging cloud server (108) is configured to authorize and facilitate communication between the messaging mobile application (110), the EV entity database server (112), and the home cloud server (104). The messaging cloud server (108) operates as a secure communication layer enabling exchange of authorization messages, operational requests, and response notifications between system components. The messaging cloud server (108) ensures that the messaging mobile application (110) can communicate with the backend servers even across different network environments, thereby supporting remote access and scalability.

[0073] In one embodiment, the messaging cloud server (108) transmits encrypted authentication data and encrypted operational commands between the EV entity database server (112) and the home cloud server (104). The encryption may be implemented using secure transport protocols, token-based authentication, and message integrity mechanisms to prevent unauthorized interception, tampering, or replay attacks. The messaging cloud server (108) thereby ensures that sensitive information such as DID validation, user mobile number authentication, and charger switching instructions remain protected throughout the communication process.

[0074] In one embodiment, the system (100) comprises an automatic switching mechanism implemented within the loT based switch (106a), wherein the automatic switching mechanism is configured to disconnect the EV charging socket (106) when the monitored electrical load falls below a predefined threshold value. This condition indicates that the charging process has completed or the vehicle is no longer drawing effective charging current. Once the load falls below the threshold for a defined duration, the home cloud server (104) triggers switching OFF of the loT based switch (106a), thereby ensuring that no power is drawn by the off-board EV charger during idle conditions. This feature conserves energy, improves safety, and increases charging socket availability for subsequent users.In a further embodiment, the predefined threshold value for automatic switching is dynamically determined based on charging characteristics of the connected electric vehicle. Such charging characteristics may include the vehicle’s battery state of charge, charging taper behavior near full capacity, or a full charge indication detected through load trends. Accordingly, the system (100) adapts to different EV models and charging profiles, minimizing false cut-offs while still ensuring that idle power draw is eliminated after charging completion.

[0075] In an optional embodiment, the system (100) further comprises an EV charging web portal (102) configured to manage multiple EV charging sockets (106) deployed across various charging locations. The EV charging web portal (102) is configured to provide monitoring and control tools such as allocation of charging slots, monitoring of charging sessions, generating energy consumption reports, displaying charging socket online / offline status, and indicating availability of sockets for next charging cycles. The web portal (102) also supports user management including uploading driver mobile numbers and vehicle number mapping for authentication, and updating such records periodically to maintain accurate authorization controls.

[0076] In one implementation, the EV charging web portal (102) is configured for fleet charging management and multi -apartment charging management where a large number of users share multiple charging sockets (106). The EV entity owner uses the EV charging web portal (102) to register authorized drivers and vehicles, configure city or hub details, and assign charging privileges. The EV entity database server (112) updates its stored authorization records based on data uploaded via the EV charging web portal (102), thereby enabling consistent validation of mobile numbers and DID-based requests received through the messaging mobile application (HO).

[0077] Accordingly, the system (100) provides a secure and cost-effective EV charging management solution that integrates QR-based authorization, messaging-based user interaction, cloud-based validation, loT switching control, and energy monitoring into a unified platform. The system (100) ensures that the EV charging socket (106) is accessible only to authorized users by validating the DID and mobile number through the EV entity database server (112), enables remote ON / OFF switching through the home cloud server (104), monitors and records energy consumption via the power metering unit, supports automatic load-based disconnection through the loT based switch (106a), and delivers real-time notifications through the messaging mobile application (110) via the messaging cloud server (108), thereby eliminating the needfor a dedicated EV charging application while improving operational efficiency for shared charging environments.

[0078] Figure 2 illustrates the block diagram of the EV charging socket (106) and working, following an embodiment of the present disclosure. The diagram represents a block diagram of an EV charging socket (106) configured for controlling the charging of Electric Vehicles (EVs). The EV charging socket (106) integrates multiple functional components to provide a secure, efficient, and remotely controllable power delivery system.

[0079] At the core of the EV charging socket (106) is the WiFi & MCU (Microcontroller Unit) module, which manages all the operations and communication within the socket. This module is equipped with WiFi capabilities, allowing the EV charging socket (106) to connect to a network for remote monitoring and control via a Messaging-based mobile application (110) or other home systems. The MCU processes data, executes requests, and communicates with other components within the EV charging socket (106).

[0080] The power metering unit is connected to the MCU via a UART (Universal Asynchronous Receiver-Transmitter) interface. This unit is responsible for monitoring the power consumption of the connected EV charger. It measures parameters such as power, providing real-time data to the MCU for processing, and also computes energy consumption during charging session. The power metering unit is essential for ensuring that the charging process is conducted efficiently and safely.

[0081] The relay is a crucial component that acts as an electronic switch controlled by the MCU. It is responsible for opening or closing the circuit that connects the power supply to the EV charger. The relay can be configured to handle high power levels safely and is controlled by signals from the MCU, enabling the EV charging socket (106) to turn the charging process ON or OFF as needed. The relay may also be integrated with a Zero-Crossing Detection feature, which helps minimize electrical noise and improve the longevity of the connected off-board EV charging system by switching at the zero-crossing point of the AC signal.

[0082] The input to the EV charging socket (106) is an AC Power Supply (240V AC, 50Hz), which is typical for residential and commercial power outlets. This power is supplied through the Neutral (N) and Live (L) wires. The EV charging socket (106) then delivers the output power, which is also 240V AC, 50Hz, to the connected EV charger via the Lx terminal.Figure 3 illustrates the architecture of Messaging Based Access And Control System For Electric Vehicle (EV) Charging, in accordance with an embodiment of the present disclosure. The EV charging web portal (102) can be a user interface that provides real time critical information necessary for the operation of the EV charging system and uploading the data to the central repository. The Messaging-Based Access And Control System (100) includes data related to the EV Fleet database (102a), City database (102b), Hub / Multi- Storey Apartment database (102c), and driver mobile number against vehicle mapping (102d). The EV Charging web portal (102) acts as the primary source of information for the system, facilitating data upload, and retrieval as needed.

[0083] The EV Entity Database Server (112) will call the API for token generation post validation and obtaining the status of the DID Home Cloud Server (104). The Home Cloud Server (104) will generate the token against the provided DID using the Home Cloud database. The Home Cloud Server (104) will send necessary information regarding EV charging socket (106) status as an API response to EV Entity Database Server (112) and subsequently, the response will be notified to the Messaging mobile application (110).

[0084] The Home Cloud Server (104) is the database of the system. It receives authorised DID information against the driver's mobile number from the EV Entity Database Server (112) and uses this information to manage the operational aspects of the system. The Home Cloud Server (104) interacts with the Internet of Things (loT) based Switch (106a) orchestrating requests and validating data to ensure secure and proper functioning of the charging process.

[0085] The EV charging socket (106) can be the physical device responsible for charging the EV. It comprises an Internet of Things (loT) based Switch (106a) and a QR Code (106b). The Internet of Things (loT) based Switch (106a) controls the power delivery to the vehicle, while the QR Code (106b) is used by drivers to initiate the charging process through a Messaging mobile application (110). The QR code (106b) contains unique identifiers that link the specific charger to the system for authorization and control purposes.

[0086] The Messaging cloud server (108) can be configured to be integrated into the system to provide communication between the driver and the home cloud server (104) through EV Entity Database Server (112). When a driver scans the QR Code (106b) using the Messaging mobile application (110), DID along with the driver's mobile number are shared with the Messaging Cloud Server (108). The Messaging cloud server (108) sends the request to EVEntity Database Server (112) through API calling. The EV Entity Database Server (112) validates thisinformation against its database and after successful validation, forwards the DID to Home Cloud Server (104). The Home Cloud Server (104) facilitates the appropriate action, such as turning ON / OFF the Internet of Things (loT) based Switch (106a) present in the EV charging socket (106).

[0087] The Messaging mobile application (110) can be the user interface through which drivers interact with the system. When a driver approaches the EV charging socket (106), they scan the QR Code (106b) using the Messaging mobile app (110). The Messaging mobile app (110) then communicates with the home cloud server (104) through the Messaging cloud server (108) and EV Entity Database Server (112) to validate the driver’s credentials and issue requests for the charging process. The Messaging mobile application (110) also provides real-time feedback to the driver regarding the status of the charger socket and facilitates actions taken by the user.

[0088] The operation begins with the EV entity inputting relevant details into the EV charging web portal (102). This information is then utilized by the EV Entity Database Server (112) to manage and authorize charging requests. When a driver arrives at a charging station, they scan the QR Code (106b) on the EV charging socket (106) using the Messaging mobile application (110). The scanned data, consisting of DID along with the driver’s mobile number, is transmitted to the Messaging cloud server (108). The server cross-references this information with the data stored in the EV Entity Database Server (112). Upon successful validation, the EV Entity Database Server (112) forwards DID to home cloud server (104). The home cloud server (104) sends a command to the Internet of Things (loT) based Switch (106a) to initiate or terminate the charging process. The Messaging-Based Access And Control System (100) ensures secure, remote control and monitoring of the charging process, providing a user-friendly experience while maintaining high levels of data integrity and operational reliability.

[0089] Figure 4 illustrates the flow chart for automatic switch-off based on Load monitoring in accordance with the disclosure. The Messaging-Based Access And Control System (100) begins with the charger being turned ON to initiate the charging of the EV. Once charging has commenced, the system continuously monitors the power load at regular intervals of every 15 minutes.

[0090] The critical decision point in this process is determining whether the load has dropped below a predefined threshold value in watts. If the Messaging-Based Access And Control System (100) detects that the load is above the predefined threshold value in watts, the charging process continues uninterrupted, ensuring that the EV receives sufficient power. However, if the loadis detected to be less than the predefined threshold value in watts, this indicates that the charging demand has significantly decreased, possibly because the battery is nearly full, or the vehicle is no longer drawing significant power. In response, the Messaging-Based Access And Control System (100) automatically triggers an API call to switch OFF the EV charging socket (106), thereby terminating the charging process. This automated shutdown mechanism helps conserve energy by ensuring no power is drawn by off-board charger in idle condition. The Messaging-Based Access And Control System (100) concludes once the charger has been successfully switched OFF, ensuring that the charging session ends safely and efficiently.

[0091] Figures 5A and 5B illustrate a flowchart that includes the steps involved in a method (200method for managing electric vehicle (EV) charging, in accordance with an embodiment of the present disclosure. The order in which method (200) is described is not intended to be construed as a limitation, and any number of the described method (200) steps may be combined in any order to implement method (200), or an alternative method. Furthermore, method (200) may be implemented by processing resource or electronic device(s) through any suitable hardware, non-transitory machine readable medium / instructions, or a combination thereof.

[0123] In another embodiment, the method may further comprise monitoring the real-time status of EV charging sockets (106), automatically switching OFF sockets when charging is complete to free them for other users and providing alerts to fleet operators or EV owners when a vehicle is ready for use.

[0124] In an embodiment, the EV charging system automatically terminates the charging process upon completion by utilizing input from a Power Metering Unit (PMU). The PMU monitors the power delivered to the vehicle in real-time, and when it detects that the power input has either reached a predefined threshold or dropped significantly indicating the battery is fully charged the system terminates the charging session. This mechanism ensures optimal energy conservation, by preventing wastage of energy by ensuring no power is drawn by off-board EV charger in idle condition, and protects the integrity of the EV battery and the charging equipment.

[0125] A few non-limiting anecdotal examples of a Messaging-Based Access and Control System (100) and method for managing electric vehicle (EV) charging, are discussed below:

[0126] In an example, a user arrives at a shared parking lot equipped with a Messaging-Based Access and Control System (100) for EV charging. The user scans the QR code (106b) associated with an EV charging socket (106) using the messaging mobile application (110) on his mobile device. The messaging mobile application (110) transmits the scanned data, including theunique device identifier (DID) and the user's mobile number, to the EV entity database server (112) for validation through the Messaging Cloud Server (108). Upon successful validation, the EV entity database server (112) sends authorization data to the home cloud server (104), which subsequently activates the loT-based Switch (106a) in the EV charging socket (106), enabling the vehicle to begin charging.

[0127] In another example, an EV fleet manager monitors the charging of multiple vehicles using the EV charging web portal (102). The portal (102) receives real-time energy consumption data from the EV entity database server (112), which aggregates information transmitted from EV charging sockets (106) via the home cloud server (104). The manager allocates charging slots based on the monitored session data and receives notifications about charging completion or errors, allowing for effective resource management and reduced downtime for the fleet.

[0128] In one example, an EV driver connects his vehicle to the EV charging socket (106) and starts charging. The integrated power metering unit in the socket (106) monitors the energy consumption during the charging session. When the monitored load drops below a predefined threshold, indicating that the EV battery is fully charged, the automatic switching mechanism in the loT-based Switch (106a) disconnects the socket (106) to conserve energy and secure the disconnection of the off-board charger. The Messaging-Based Access and Control System (100) notifies the driver via the messaging mobile application (110) about charging completion and frees the socket for other users.

[0129] In an example, an EV owner receives a real-time notification on his messaging mobile application (110) about an error during the charging process. The messaging cloud server (108) relays the error alert from the home cloud server (104), enabling the user to take corrective action. The notification provides details about the error and suggests reconnecting the vehicle to resolve the issue. This timely alert minimizes charging disruptions and ensures that the user can rely on the Messaging-Based Access and Control System (100) for seamless EV charging.

[0130] In one more example, a multi -apartment complex uses the Messaging-Based Access and Control System (100) to manage shared EV charging resources. Residents book charging slots through the EV charging web portal (102), which allocates time slots based on availability. Each resident scans the QR code (106b) on the assigned EV charging socket (106) to start his / her session. The EV entity database server (112) validates his / her credentials and sends operational requests to the home cloud server (104) to enable charging. The Messaging -BasedAccess And Control System (100) tracks each resident's energy consumption, generates individual usage reports, and ensures that all users are billed accurately for their sessions.

[0131] In an operative configuration, the Messaging -Based Access and Control System (100) seamlessly integrates the EV charging socket (106), home cloud server (104), EV entity database server (112), messaging cloud server (108), and the messaging mobile application (110) to enable secure and efficient electric vehicle (EV) charging management. The EV charging socket (106), equipped with a power metering unit and an loT-based Switch (106a), interacts with the home cloud server (104) to execute user requests for enabling or disabling charging. The QR code (106b) simplifies user authentication via the mobile application (110), which communicates with the EV entity database server (112) through the messaging cloud server (108) to validate credentials and manage the charging process. Real-time data on energy consumption, charging status, and notifications are relayed to the user, while operational requests are executed reliably, ensuring effective coordination across all system components.

[0132] Advantageously, the Messaging-Based Access and Control System (100) and method 200 offer several advantages over traditional EV charging solutions. By leveraging EV charging sockets (106) with QR code-based authentication, the system eliminates the need for dedicated mobile applications, enhancing user accessibility and convenience. The integrated power metering unit provides accurate energy consumption monitoring, enabling detailed reporting and transparent billing. Automatic switching mechanisms conserve energy by safe disconnection of off-board charger EV charger to ensure no power is drawn in idle conditions and freeing idle sockets for other users. Furthermore, the use of cloud-based servers ensures secure communication, scalability, and remote operability, making the system suitable for fleet management, multiapartment complexes, and shared EV charging infrastructures. Real-time notifications and an intuitive web portal (102) enhance user experience and operational efficiency, offering a cost-effective and future-ready solution for managing EV charging at scale.
