As such, the present disclosure should be construed to extend to any alterations, equivalents and substitutes in addition to those which are particularly set out in the accompanying drawings. Although the terms first, second, etc. may be used herein to describe various elements, these elements should not be limited by these terms. These terms are generally only used to distinguish one element from another.

[0026] The present disclosure provides a system for handling energy measurement. The system includes a Direct Current (DC) charger, where one end of the DC charger is connected with an Alternate Current (AC) source and another end of the DC charger is connected with a battery. An energy meter is integrated within the DC charger. The energy meter includes a voltage sensor measuring a voltage value from the AC source and a current sensor measuring a current value from the AC source. The voltage sensor and the current sensor send the voltage value and the current value to a processor through a communication unit. The processor computes energy usage based on the voltage value and the current value.

[0027] In one of the embodiments, the system takes in AC power from an input source (e.g., AC source or the like) and converts the AC power into DC power using the DC charger. The AC input is connected to the DC charger, which then provides regulated DC power to the battery. The smart energy meter tracks the energy consumed during a charging process, i.e., how much AC power is converted into DC power and subsequently stored in the battery. An Internet-of-Things (IoT) capability of the energy meter allows it to communicate the energy consumption data via a network. This can be useful for remote monitoring and tracking of battery charging cycles, energy consumption patterns, or for reporting usage to a server, a central system, a central platform, a cloud platform, and an electronic device. The DC charger is designed to safely charge the battery by providing the correct voltage (58.8V, for example) and current (6A, for example). This ensures efficient and controlled charging, which is critical to prolonging the lifespan of the battery. Once fully charged, the battery can be disconnected and used to power devices or systems requiring DC power.

[0028] In other words, the present invention relates to an integrated system for charging battery and measurement of energy, and more particularly to the energy meter integrated within the DC charger designed for electric vehicles, leveraging Internet of Things (IoT) technology for enhanced energy monitoring and management. By enabling remote monitoring and data analytics, the proposed method and system empowers users and operators to optimize energy usage, reduce costs, and improve overall operational efficiency.

[0029] The proposed method and system utilizes advanced direct DC measurement capabilities with high-precision sensing technology to achieve significantly higher accuracy. The system incorporates real-time data sampling and intelligent metering technique optimization, providing superior performance compared to traditional energy measurement solutions. The enhanced measurement accuracy contributes to improved system reliability, reduced installation complexity, and better cost efficiency. Additionally, the system offers an improved user experience through real-time data access, enabling more efficient billing and payment processing while supporting future smart grid integration. Its single-unit construction simplifies installation compared to distributed systems and allows for the cost-effective integration of both charging and metering functions into one device. The proposed method and system also reduce maintenance requirements. Furthermore, real-time monitoring capabilities, temperature compensation features (for example, the energy meter operates reliably within –20°C to 50°C, supported by forced fan convection cooling inside the DC charging system; if the temperature exceeds this range, the DC charger automatically disconnects to protect both the energy meter and the battery), and high-power measurement accuracy ensure that the system maintains consistent performance even under varying environmental conditions.

[0030] The proposed system and method ensure real-time monitoring of energy consumption, facilitates remote management capabilities via the IoT connectivity, guarantees secure data transmission and user authentication, and provides enhanced energy management for DC charging systems. Further, the proposed system and method improves energy efficiency by providing real time usage data, facilitates accurate billing and energy consumption tracking, and offers a comprehensive solution for monitoring EV (Electric Vehicle) charging systems.

[0032] Referring now to the drawings, and more particularly to Figures 1 through 5, where similar reference characters denote corresponding features consistently throughout the figures, there are shown embodiments.

[0033] Referring to Figure 1 to Figure 4, Figure 1 illustrates a block diagram of a DC charger (100) having an energy meter (e.g., smart energy meter, IoT energy meter or the like) (120). Figure 2 illustrates an example system (200) depicting a circuit diagram of the energy meter (120) integrated within the DC charger (100). Figure 3 is an example illustration (300) in which the system (200) communicates with an electronic device (302) and a server (304). The electronic device (302) may be, for example, but not limited to a laptop, a smart phone, a desktop computer, a notebook, a vehicle to everything (V2X) device, a foldable phone, a smart TV, a tablet, a television, a connected car, an immersive device, an internet of things (IOT) device, or any other device that can communicate using a wireless network. The server (304) may be, for example, but not limited to an edge server, a cloud server, a remote server or the like. Figure 4 is an example screenshot in which a display (400) of the electronic device (302) shows various values measured by the energy meter (120).

[0034] As shown in Figures 1- 3, the system (200) includes a DC charger (100) having the energy meter (120). One end of the DC charger (100) is connected with an AC source (202) and another end of the DC charger (100) is connected with a battery (204). The DC charger (100) converts an incoming AC power from the AC source (202) into DC power suitable for charging the battery (204).

[0035] The DC charger (100) can be, for example, but not limited to an electric vehicle (EV) fast charger like a Combined Charging System (CCS) and CHAdeMO chargers, and also a portable DC charger for any other compatible electronic device. The battery (204) may be, for example, but not limited to a Lithium-Ion (Li-ion) rechargeable battery, a Lithium Nickel Manganese Cobalt Oxide (NMC) battery, a lead-acid battery, a nickel-metal hydride (NiMH), a Nickel-Cadmium (NiCd) battery, a Lead-acid battery, and any other energy storage component. The AC source (202) provides an AC input, typically at 180V-240V, to the DC charger (100). In an example, the DC charger (100) may charge a 48V lithium battery, with an input AC voltage of 180-240V and output DC of 58.8V, 6A.

[0036] The energy meter (120) tracks the power consumed from the AC source (202), converts the AC to DC at the DC charger (100), and charges the battery (204) while sending data over the wireless network (not shown) for remote monitoring. In an example, the size of the energy meter (120) is 80 millimeters (mm) in length, 50 mm in width, and 30 mm in height.

[0037] In an embodiment, the energy meter (120) includes at least one voltage sensor (e.g., ZMPT101B or the like) (122), at least one current sensor (e.g., SCT-013-030, ACS712 -30A or the like) (124), a processor (126), a communication unit (128), a SIM (130), an AC-DC converter (132), a relay (134), a DC-DC converter (136) (e.g., TP4056 or the like), a cell (138) (e.g., battery cell, lithium-ion polymer cell, Nickel-Manganese-Cobalt Lithium-ion battery cell (may have a rating as 3.7V/600mAh) or the like), a wire connector (140), a Printed Circuit Board (PCB) (142) and at least one protective component (144).

[0038] The at least one voltage sensor (122) measures a voltage value from the AC source (202) and the at least one current sensor (124) measures a current value from the AC source (202). The at least one voltage sensor (122) and the at least one current sensor (124) send (or transmit) the voltage value and the current value to the processor (126) through a communication unit (128).

[0039] A plurality of sensors (i.e., at least one voltage sensor (122), at least one current sensor (124), for example) measures an AC current, an AC voltage and provides data to the processor (126) necessary for calculating power consumption. The processor (126) processes the data about the AC current and the AC voltage received from the plurality of sensors (122, 124). In other words, the current sensor (124) and the voltage sensor (122) measure the current and voltage from an AC line respectively. The processor (126) reads the analog signals from the voltage and current sensors (122, 124), and processes the data (e.g., calculating real-time power, energy usage, etc.). Using the communication unit (128), the system (200) transmits the energy readings wirelessly to the server (304), an application running in the electronic device (302), or other cloud-based monitoring systems.

[0040] The term ‘processor (126)’ as used in the present disclosure, may refer to, for example, hardware including logic circuits; a hardware/software combination such as a processor executing software; or a combination thereof. For example, the processing circuitry more specifically may include, but is not limited to, a central processing unit (CPU), an arithmetic logic unit (ALU), a digital signal processor, a microcomputer, a field programmable gate array (FPGA), a System-on-Chip (SoC), a programmable logic unit, a microprocessor, application-specific integrated circuit (ASIC), etc. For example, the processor (126) may include at least one of, a single processer, a plurality of processors, multiple homogeneous or heterogeneous cores, multiple Central Processing Units (CPUs) of different kinds, microcontrollers, special media, and other accelerators.

[0041] The processor (126) computes energy usage (e.g., power usage) based on the voltage value and the current value received from the plurality of sensors (122, 124). The energy consumed in each charging is calculated by a formula Voltage x Current x Charging time. The processor (126) shares the computed energy usage, the voltage value and the current value to at least one of: the electronic device (302) and the server (304) through the communication unit (128). The communication unit (128) , by using a GSM unit (128a), establishes a communication link between the energy meter (120) and at least one of: the electronic device (302) and the server (304) using secure data encryption and transmission techniques. The electronic device (302) and the server (304) enable a user to track the energy usage and optimize energy efficiency and control a risk of at least one of: an overload and a malfunction of the energy meter (120) and the battery (204) due to over-current, over-voltage or the like.

[0042] The processor (126) performs a remote monitoring and tracking of a battery charging cycle, an energy consumption pattern, and reporting energy usage to at least one of: the electronic device (302) and the server (304) through the communication unit (128).

[0043] The communication unit (128) is configured for communicating internally between internal hardware components of the system (200) and with external devices via one or more networks. In an embodiment, the communication unit (128) includes an electronic circuit specific to a standard that enables wired or wireless communication. The communication unit (128) can be, for example, but not limited to the Global System for Mobile Communication (GSM) unit (128a) (e.g., GSM800L or the like) and antenna (128b), fourth-generation (4G) wireless unit, a fifth-generation (5G) wireless unit, a sixth generation (6G) network unit, a Wi-Fi unit, Bluetooth, ZigBee or the like.

[0044] The AC-DC converter (132) in the energy meter (120) is responsible for converting the AC from the AC source (202) into the DC, which is then used to charge the battery (204). This process begins with rectification, where AC voltage is transformed into unregulated DC using a rectifier circuit, often followed by a power factor correction (PFC) stage to improve efficiency and ensure compliance with grid standards by minimizing harmonic distortion. The PFC stage shapes the input current waveform to align closely with the voltage waveform, achieving a high power factor and reducing stress on the grid. After rectification and PFC, the resulting DC voltage is filtered and regulated to provide a stable DC output that can be further processed by the DC-DC converter stage. Additionally, the AC-DC converter (132) includes protective features such as input surge protection, overvoltage protection, and thermal monitoring to ensure reliable operation under varying grid conditions. It may also interface with the processor (126) to adjust power flow based on demand, battery status, or grid signals. Overall, the AC-DC converter (132) is essential for safely and efficiently transforming the AC power into a usable DC form for downstream charging operations. In an example, AC-DC converter (132) converts standard 220-volt alternating current (AC) from the AC source (202) into a stable 5.29-volt direct current (DC) output, suitable for powering the battery (204).

[0045] The relay (134) in the energy meter (120) serves as a crucial switching device that controls the connection and disconnection of electrical circuits, ensuring safe and reliable operation during the charging process. Its primary function is to allow or interrupt the flow of current between the DC charger (100) and the battery (204) based on control signals from the processor (126) or a battery management system (BMS) (not shown). At the beginning of a charging session, the relay (134) remains open until all safety checks such as correct voltage levels, proper communication with the BMS, and fault detection - are successfully completed. Once the system (200) confirms safe conditions, the relay (134) closes to establish the electrical connection, allowing current to flow from the charger (100) to the battery (204). During charging, the relay (134) also acts as a protective component by disconnecting the circuit in case of faults such as overcurrent, overvoltage, reverse polarity, or overheating. In addition, when charging is complete or manually stopped, the relay (134) opens to isolate the battery (204) from the charger (100), preventing any unintended current flow. In high-power DC chargers, especially for electric vehicles, the relay (134) is typically used in conjunction with contactors and is designed to handle large currents while providing electrical isolation when needed. Overall, the relay (134) enhances both the safety and control of the charging process by managing when and how power is delivered to the battery (204).

[0046] The DC-DC converter (136) in the energy meter (120) plays a vital role in regulating and converting electrical energy to meet the specific requirements of the battery (204) during charging. The DC-DC converter (136) takes a DC input, either from the rectified AC source (202) or a DC power supply, and converts it to a different DC voltage and current suitable for the connected battery (204). Depending on the application, the DC-DC converter (136) may function as a buck (step-down), boost (step-up), or buck-boost converter to either decrease or increase the voltage level. During the charging process, the DC-DC converter (136) operates in two primary modes: constant current (CC) mode, where a fixed current is supplied until the battery voltage reaches a predefined level, and constant voltage (CV) mode, where the voltage is maintained at a constant value while the current gradually decreases as the battery nears full charge. The DC-DC converter (136) also integrates various protection mechanisms such as overvoltage, overcurrent, short-circuit, and thermal protection to ensure safe operation. Overall, the DC-DC converter (136) ensures that the battery is charged efficiently, safely, and within its specified limits, making it a critical component in DC charging systems, especially in applications like electric vehicle (EV) fast charging.

[0047] The at least one protective component (144) provides a stability and protection for at least one element (e.g., sensitive electronics element or the like) in the energy meter (120). The at least one element comprises at least one of: the at least one voltage sensor (122), the at least one current sensor (124), the processor (126), the communication unit (128), the SIM (130), the AC-DC converter (132), the relay (134), the DC-DC converter (136) and the cell (138).

[0048] In an example, resistors and capacitors provide stability and protection for the sensitive electronics element. In another example, a set of resistors (e.g., 10kO and 100O) is used for current limiting and voltage divider components are used ensuring accuracy of the plurality of sensors (122, 124), and a set of capacitors (50V, 10µF) is used for storing energy, filtering, and smoothing the power supply. The resistors and the capacitors help manage and regulate the power flow, ensuring stable operation for all components, especially for the sensitive processor (126) and the sensors (122, 124).

[0049] The SIM (130) further supports the communication in the energy meter (120). The SIM (130) authenticates the user to receive an accurate billing of the energy usage. The cell (138) may be used to power the energy meter (120) and components thereof.

[0050] The inbuilt energy meter (120) further includes the wire connector (140) with pins facilitating connections between electrical components. The PCB (142) provides physical and mechanical support and connects the at least one element in the energy meter (120). The PCB (142) holds all the components mentioned above.

[0051] Based on the above operations, the DC charger (100) controls a charging process, so as to ensure that the battery (204) receives an optimal voltage (or correct voltage) and optimal current (or correct current) for optimal and safe charging of the battery (204).

[0052] Figure 2 illustrates the system (200) depicting a circuit diagram of the energy meter (120) integrated within the DC charger (100). The circuit diagram shows the connections of the aforementioned components in the IoT-based energy monitoring and control system for the DC charger (100). The system (200) begins with the AC input, which is fed into both the voltage sensor (122) and the AC-DC converter (132). The voltage sensor (122) measures the input voltage and sends the data to a microcontroller (126a) (e.g., ESP32), while the AC-DC converter (132) converts a high-voltage AC (e.g., 220V) to a low-voltage DC output, which powers other low-voltage components such as the microcontroller (126a) and the sensors (122, 124).

[0053] The current sensor (124) is connected in series with an output load path to measure the current flowing through the circuit and also sends its data to the microcontroller (126a). The microcontroller (126a) receives the voltage data and the current data, calculates power and energy consumption, and communicates this data using a GSM module (128a). The GSM module (128a), equipped with an antenna (128b), allows the system (200) to send real-time energy usage data to the electronic device (302) and the server (304). Hence, the energy meter (120) finds use of the voltage and current in real-time energy monitoring and data logging, which can be accessed remotely via cellular communication.

[0054] The energy meter (120) includes the relay (134) that acts as a switch to control the connection between the AC-DC converter (132) and the output load path. The relay (134) is controlled by the microcontroller (126a) based on programmed conditions or remote commands. The DC-DC converter (136) is used to step down the DC voltage further to charge a cell (battery), ensuring appropriate voltage and current levels for charging. Finally, the output labeled “O/P Towards Charger” delivers the regulated DC power to an external charger or load, for e.g., the battery (204), wherein the battery (204) may be used in the EV or other compatible systems.

[0055] Figure 4 is an example screenshot in which the display (400) of the electronic device (302) shows various values measured by the energy meter (120). Because of the IoT capability, the energy meter (120) sends all the relevant data to the server (304), which can be viewed/accessed from the electronic device (302). A user associated with the energy meter (120) can access the relevant data from an assigned dashboard using the electronic device (302). In the current example, an energy meter dashboard shows that the battery (204) is currently offline. The recorded voltage (Vrms) is 220.42 volts, the current (Irms) is 2.94 amperes, the power consumption is 480.72 watts, and the total energy consumed is 7.07 kilowatt-hours (kWh). The data displayed corresponds to a selected timeframe of 1 hour, and the device is associated with a user named Vinod and an organization labeled "My organization - 6619YW. This type of display of data helps the user to understand, monitor and manage the energy consumption.

[0056] Figure 5 is a flow chart (500) illustrating a method for handling energy measurement by the energy meter (120).

[0057] At 502, the method includes measuring, by the voltage sensor (122) integrated within the energy meter (120), the voltage value from the AC source (202). At 504, the method includes measuring, by the current sensor (124) integrated within the energy meter (120), the current value from the AC source (202). At 506, the method includes transmitting, by the voltage sensor (122) and the current sensor (124), the voltage value and the current value to the processor (126) via the communication unit (128).

[0058] At 508, the method includes computing, by the processor (126), the energy usage based on the received voltage value and current value and transmit the same via the communication unit (128) to at least one of: the electronic device (302) and the server (304). The energy consumed in each charging is calculated by the formula Voltage x Current x Charging time.
