Description:FIELD OF THE INVENTION
[001] Present invention relates to a charging system. Embodiments of the present invention relate to a system for charging a battery pack and a method thereof.

BACKGROUND OF THE INVENTION
[002] With the advancement in vehicle technologies, there is greater focus on enhancement of a battery performance, and on improving an overall charging experience. A charger is a device configured to charge a battery pack, which can be of a vehicle. The charger is configured to charge the battery pack by routing a charging current from a power source to the battery pack. A conventional charger is configured to charge the battery pack only in a single mode i.e., either a high power level mode (fast charging) or a low power level mode. The chargers that are capable of charging the battery pack at the high power level mode are high wattage chargers, while the chargers that are capable of charging the battery pack at the low power level mode are low wattage chargers.
[003] Generally, the high wattage charger is required to be connected to a power source of high grid capacity (for example plug points of power capacity of 3kW) for efficient charging of the battery pack. However, these high grid capacity power sources are scarce and thus, in some instances, the high wattage chargers are required to be connected to low grid capacity power sources, which comprises plug points at residential locations with a capacity of 1.5kW, for charging the battery pack. The high wattage chargers are inefficient in charging the battery pack, while being connected to the low grid capacity power sources due to its incompatibility, rendering power loss, which is undesirable.
[004] In view of the above, for ensuring maximum utilization of power from the power source, the user may be required to carry both the high wattage charger and the low wattage charger. Thus, based on the capacity of the power source available, the user can connect the relevant charger for maximum utilization of power and charging of the battery pack. However, carrying both the chargers is cumbersome to the user, which makes the charging process tedious and laborious. Additionally, the user may be required to purchase one of the chargers, since both the low wattage and high wattage chargers are not supplied by vehicle manufacturer with the vehicle. Thus, an additional cost is incurred to the user, making the overall cost of the vehicle high. Moreover, accommodating two chargers in the vehicle occupies storage space in the vehicle, which is undesirable. Also, in case of a two-wheeled vehicle, the storage space is already very less and the accommodation of two chargers further increases the space problem. The accommodation of two chargers also leads to an increase in the overall weight of the vehicle, which is undesirable.
[005] Thus, there is a need in the art for a system and a method for charging a battery pack, which addresses at least the aforementioned problems.

DETAILED DESCRIPTION OF THE INVENTION
[017] Present invention generally relates to a charging system. More particularly, the present invention relates to a system for charging a battery pack and a method thereof.
[018] Figure 1 illustrates a block diagram for the system 100 for charging the battery pack 102, in accordance with an embodiment of the present invention. The present invention provides the system 100 for charging the battery pack 102. As disclosed herein, the battery pack 102 comprises one or more batteries connected together in a series connection, a parallel connection or a series-parallel connection as per requirement. In an embodiment, the vehicle 10 is a two-wheeled vehicle, a three-wheeled vehicle, a four-wheeled vehicle and a multi-wheeled vehicle. In yet another embodiment, the vehicle 10 is an electric vehicle or a hybrid vehicle. In an embodiment, the battery pack 102 is configured to be disposed in the vehicle 10. The battery pack 102 is configured to provide the desired power output for the functioning of the vehicle 10. In an embodiment, the battery pack 102 is disposed on a frame member (not shown) of the vehicle 10.
[019] The system 100 further comprises a charger unit 104. The charger unit 104 is connectable to the battery pack 102 and to a power source 108. The charger unit 104 upon electrically connecting the charger unit 104 to the power source 108 and the battery pack 102, is adapted to supply or provide a charging current to the battery pack 102 from the power source 108. In an embodiment, the charger unit 104 comprises one or more electrical components that are configured to convert or modulate the power received from the power source 108 for charging the battery pack 102. In an embodiment, the one or mor electrical components are configured to convert Alternating Current (AC) power (or current) from the power source 108 and converts it into Direct Current (DC) power. In an embodiment, the charger unit 104 is capable of being connected to a DC charging power point. In this, the charger unit 104 facilitates the conversion of the AC power from the grid into the DC power required for charging the battery pack 102. Therefore, the charger unit 104 is adapted to different power sources, including those providing the DC power, making it versatile in terms of compatibility with various charging infrastructures. The DC power is then delivered to the battery pack 102 of the vehicle 10.
[020] In an embodiment, the charger unit 104 is adapted to provide a charging current to the battery pack 102 based on the grid capacity and the power demand. The grid capacity refers to the maximum amount of an electrical power that a power grid or an electrical system is able to supply at a given time. More specifically, the charging process is not carried out indiscriminately. Rather, the charger unit 104 is configured to consider the grid capacity and the power demand. Hence, the charging current provided to the battery pack 102 is adjusted based on the capacity of the power grid and the specific power requirements at the given time. In essence, the charger unit 104 acts as an intelligent intermediary, optimizing the charging process to align with the capabilities of the overall power infrastructure and the immediate power needs of the system 100.
[021] In an embodiment, the charger unit 104 is a power demand control-based charger unit i.e., the charger unit 104 is able to charge the vehicle 10 as per power demand requirement from a user. In an embodiment, the charger unit 104 is adapted to charge the battery pack 102 in a high power level mode and in a low power level mode. In an embodiment, the high power level mode refers to a fast charging mode, wherein the charger unit 104 is capable of fast charging the battery pack 104. In an embodiment, the charger unit 104 in the high power level mode has a default setting, such as of 3kW capacity. In an embodiment, the charger unit 104 is adapted to be operable in the high power level mode, when connected to a high wattage or high grid capacity power source 108 such as commercial grid stations.
[022] In an embodiment, the low power level mode refers to a mode wherein the charger unit 104 has a default setting of 1.5kW power output setting. In an embodiment, the charger unit 104 is adapted to be operable in the low power level mode, when connected to a low wattage or low grid capacity power source 108 such as plug points at residential places, wherein the power supply is less as compared to the commercial places.
[023] The system 100 comprises a control unit 106 that is communicably coupled to the charger unit 104 and the battery pack 102. In an embodiment, the control unit 106 is connected to the charging unit 104 and the battery pack 102 wirelessly. In an embodiment, the control unit 106 is operatively connected to the one or more electrical components in the charger unit 104. The control unit 106 is configured to charge the battery pack 102 of the vehicle 10 with the help of the charger unit 104. In an embodiment of the present invention, the control unit 106 is a Vehicle Control Unit (VCU) 106 and is adapted to determine one or more operating parameters of the vehicle 10. In an embodiment, the one or more operating parameters of the vehicle 10 include but not limited to a speed of the vehicle 10, a brake actuation, a throttle actuation, parameters pertaining to the battery pack 102 and the like. One or more sensors (not shown) are installed on the vehicle 10 and are configured to procure information pertaining to each of the one or more operating parameters and parameters pertaining to the battery pack 102. In an embodiment, the one or more sensors comprises but is not limited to a battery monitoring sensor, a vehicle speed sensor, and the like.
[024] As disclosed herein, the control unit 106 is configured to determine at least one of the grid capacity of the power source 108 and the one or more battery parameters of the battery pack 102. In an embodiment, the grid capacity is the maximum power output available on an electrical grid for a given time period or based on a load connected to the power source 108. Also, the control unit 106 is configured to determine the grid capacity when the charger unit 104 is connected to the power source 108. In an embodiment, the one or more battery parameters include but are not limited to a voltage of the battery, a battery capacity, a charging current, a discharging current, and the like. In an embodiment, the control unit 106 is configured to receive an input from a user corresponding to a charging power demand. As disclosed herein, the charging power demand is decided by the user based on the requirement of the battery pack 102. In an example, the charging power demand may be selected by the user based on the one or more battery parameters and availability of the low wattage charger or the high wattage charger. If the battery pack 102 of the vehicle 10 is 50% charged, then the user may decide to further charge the battery pack 102 to 100% at the low power level mode to increase the efficiency and the durability of the battery pack 102. Similarly, if the battery pack 102 of the vehicle 10 is at 10%, then the user may select to charge the vehicle at the high power level mode i.e., fast charging of the battery pack 102. Accordingly, the user is able to customize the charging power demand based on the one or more battery parameters.
[025] The control unit 106 further determines the charging current corresponding to the at least one of the grid capacity of the power source 108, the one or more battery parameters of the battery pack 102 and the charging power demand received from the user. In an example, if the battery is at 10% and the user has selected the battery to be charged at the high power level mode, then the user may connect the charger unit 104 at the commercial place, wherein the grid capacity is 3kW. The charging current is accordingly supplied, say at 6A, to the battery pack 102 for charging the battery pack 102. In an embodiment, the control unit 106 is also adapted to determine the charging current corresponding to the at least one of the grid capacity of the power source 108, the one or more battery parameters of the battery pack 102 and the one or more operating parameters of the vehicle 10.
[026] Once the charging current is determined, the control unit 106 is configured to enable the charger unit 104 by operating one or more electrical components for providing the charging current to the battery pack 102 for charging. Therefore, the present invention is configured to charge the battery pack 102 of the vehicle with the help of the charger unit 104. In an embodiment, the control unit 106 is configured to store the charging current, the grid capacity of the power source 108, the one or more battery parameters of the battery pack 102 and the charging power demand received from the user.
[027] Figure 2 illustrates a flow diagram for a method 200 for charging the battery pack 102, in accordance with an embodiment of the present invention. The steps involved in the method 200 for charging the battery pack 102 of the vehicle 10 are illustrated in Figure 2. As illustrated in Figure 2, a charging current to the battery pack 102 is provided by the charger unit 104. As disclosed herein, the battery pack 102 comprises the one or more batteries connected together in the series connection, the parallel connection or the series-parallel connection as per the requirement. In an embodiment, the battery pack 102 is configured to be disposed in the vehicle 10. The battery pack 102 is configured to provide the desired power output for the functioning of the vehicle 10.
[028] The charger unit 104 is connectable to the battery pack 102 and the power source 108. In an embodiment, the charger unit 104 upon electrically connecting the charger unit 104 to the power source 108 and the battery pack 102, is adapted to supply or provide a charging current to the battery pack 102 from the power source 108. In an embodiment, the charger unit 104 is the power demand control-based charger unit i.e., the charger unit 104 is able to charge the vehicle 10 in both the modes, namely, the high power level mode and the low power level mode.
[029] At step 202, the method determines at least one of the grid capacity of the power source 108 and the one or more battery parameters of the battery pack 102 by the control unit 106. In an embodiment of the present invention, the control unit 106 is the Vehicle Control Unit (VCU) and is adapted to determine the one or more operating parameters of the vehicle 10. In an embodiment, the one or more operating parameters of the vehicle 10 include but not limited to a speed of the vehicle 10, a brake actuation, a throttle actuation, parameters pertaining to the battery pack 102 and the like. In an embodiment, the grid capacity is the maximum power output available on the electrical grid for the given time period or based on a load connected to the power source 108. Also, the control unit 106 is configured to determine the grid capacity when the charger unit 104 is connected to the power source 108. In a further embodiment, the one or more battery parameters include but are not limited to a battery voltage, a battery capacity, a charging current, a discharging current, and the like. In an embodiment, the control unit 106 is configured to receive an input from a user corresponding to the charging power demand. As disclosed herein, the charging power demand is decided by the user based on the requirement of the battery pack 102.
[030] At step 204, the control unit 106 determines the charging current corresponding to the at least one of the grid capacity of the power source 108, the one or more battery parameters of the battery pack 102 and the charging power demand received from the user. In an embodiment, the control unit 106 is also adapted to determine the charging current corresponding to the at least one of the grid capacity of the power source 108, the one or more battery parameters of the battery pack 102 and the one or more operating parameters of the vehicle 10.
[031] As further illustrated in Figure 2, at step 206, the control unit 106 enables the charger unit 104 by operating the one or more electrical components for providing the charging current to the battery pack 102 for charging. Therefore, the present invention is configured to charge the battery pack 102 of the vehicle with the help of the single charger unit 104. In an embodiment, the control unit 106 is configured to store the charging current, the grid capacity of the power source 108, the one or more battery parameters of the battery pack 102 and the charging power demand received from the user. Hence, the control unit 106 is adapted to provide the charging current to the battery pack 102 of the vehicle 10.
[032] Figure 3 illustrates a flow diagram for the method 300 for charging the battery pack 102, in accordance with an exemplary embodiment of the present invention. As illustrated in Figure 3, the method 300 is shown for charging the battery pack 102. The method starts at step 302. In an embodiment, the VCU 106 is provided which is configured to detect the charger unit 104. The VCU 106 is an electronic component which helps in communicating between a Battery Management System (BMS) of the battery pack 102, a charge monitoring unit, a motor unit and an electrical load control unit. The VCU 106 is configured to receive an information related to monitoring, sensing, charging and communication related information. Based on the information received, the VCU 106 is adapted to take the decision. In an embodiment and as shown at step 304, the charger unit 104 is detected by the VCU 106. The charger unit 104 is a standalone unit. The charger unit 104 is configured to draw Alternating Current (AC) power from the power source 108 and convert it into Direct Current (DC) power. The DC power is then delivered to the battery pack 102 of the vehicle 10. In an embodiment, the vehicle 10 is provided with a connector, wherein the charger unit 104 is mounted on the connector. The connector engages the charger unit 104 onto a power busbar of the vehicle 10. In an embodiment, the AC charger unit is an off-board charger unit to be connected between a charging point on the vehicle 10 and a power plug point at residential places or at a charging station.
[033] As illustrated in Figure 3 at step 306, the VCU 106 is configured to check a charging power demand selected by the user. Then, the charging power demand is received by the VCU 106. In an embodiment, the charging power demand is selected by the charging port as well via a Controller Area Network (CAN) communication for charging the battery pack 102 of the vehicle.
[034] In yet another embodiment, the charger unit 104 can automatically change the charging power demand mode based on the power supply available at the charging plug point. This is particularly based on a prior usage of the charging plug point. In an embodiment, the charger unit 104 can stop power supply if a high ampere current is supplied to the charger unit 104 beyond the rated current/power of the charger unit 104 to stop a power tripping of the power supply area. The charger unit 104 may have a fuse for safety from such situations. Further, the charger unit 104 can send signals corresponding to an output power supplied for charging the battery pack 102 to the VCU 106.
[035] At step 308, the charger unit 104 supplies the corresponding charging power demand to the battery pack 102 for charging. The method then checks whether the battery pack 102 is fully charged at step 310. If the battery pack 102 is fully charged, then the method is terminated at step 312. If not, then the battery pack 102 continues to charge until it is fully charged.
[036] Figure 4 illustrates a flow diagram for the method 400 for a charging power demand setting, in accordance with an exemplary embodiment of the present invention. As illustrated in Figure 4, the method has an infotainment system (not shown). The infotainment system is a cluster including a speedometer, a display, a control unit, and the like. The infotainment system is configured to coordinate between a user device and the control unit 106. The infotainment system is configured to enable a secure communication between the user device and the control unit 106. The method starts at step 402, wherein the vehicle 10 is at an idle condition and an ignition of the vehicle 10 is in ON condition.
[037] At step 404, the user selects the charging power demand through an application from a user device. The application is connected to the infotainment system via a secure wireless protocol. At step 406, the infotainment system receives the charging power demand through the application of the user device.
[038] Further, as illustrated at step 408, the infotainment system receives the data from the application and initiates an extended Unified Diagnostics Services (UDS) session with the VCU 106 by triggering an appropriate command via a secure handshake. In an embodiment, the UDS is a diagnostic communication protocol used in the control units within automotive electronics. Then at step 410, the VCU 106 receives the charging power demand value from the infotainment system and stores the charging power demand in a memory.
[039] In an exemplary embodiment, during the charging of the battery pack 102, the VCU 106 takes the charger setting from the memory. The infotainment system is operatively connected to the VCU 106 and the infotainment system is configured to receive one or more command signals. The command signals are associated with a mode of the charging power demand for charging the vehicle 10. Upon successful connection between the infotainment system and the VCU 106, the VCU 106 receives the charging power demand value from a speedometer of the infotainment system. The VCU 106 detects the charger unit 104 for charging the battery pack 102. The VCU 106 refers to the latest charger power demand setting and demands the required power associated with the mode of charging power demand.
[040] The VCU 106 or a master control unit receives an input from all other control units such as speed of the vehicle 10, an Anti-Braking System (ABS) signal, and the like from a motor control unit (not shown). The VCU 106 then receives a battery cell voltage, a battery pack voltage, an output current rating, the charging power demand, charging confirmations, and the like from the BMS. The VCU 106 then receives the user input, the charging power demand, and other associated instructions through the infotainment system. Based on the received inputs, the VCU 106 takes the decision accordingly.
[041] In yet another example, the AC charger has a default setting of either 1.5 kW power output setting or 3kW power output setting. If the user wants to change the output power setting of the charger unit, the user turns on the vehicle in the idle mode and sends a message or a request to the infotainment system for changing the power setting through the mobile device application. The infotainment system receives the request though a network such as Bluetooth. Further, the infotainment system sends the command to enter the extended session with the VCU 106 and do a secure handshake, i.e., a security clearance with the VCU 106. Once the secure handshake is confirmed and the security is elevated, the new requested charging current setting is sent to the VCU 106 and the VCU 106 stores it in the memory. Whenever, the charger unit 104 is connected, the VCU 106 demands the power from the charger unit 104 according to the saved current setting. When the VCU 106 detects the charger unit 104 connection for charging, the VCU 106 checks the memory, and accordingly the VCU 106 demands the power from the charger unit 104 till the battery pack 102 is fully charged.
[042] In an embodiment, once the charging power demand mode is setup in the VCU 106, it remains as the default setting until the user change it again. Thus, the same charger unit 104 performs efficiently based on the charging power demand by the user and according to the availability of high wattage power supply and low wattage power supply at the charging plug point for charging the battery pack 102 of the vehicle 10.
[043] In an embodiment, when the VCU 106 detects the presence or connection of a charger unit 104 for the purpose of charging the electric vehicle, then the VCU 106 initiates a series of actions. The VCU 106 refers to the internal memory where it stores the required charging power mode. The stored information includes details about the optimal charging power levels suitable for the electric vehicle. Subsequently, the VCU 106 communicates with the charger unit 104, demanding the specified power levels necessary for charging the battery pack 102. Throughout the charging process, the VCU 106 monitors and manages the power transfer, ensuring that it aligns with the predetermined settings stored in the memory. This systematic approach not only facilitates efficient charging but also safeguards against potential unauthorized access or manipulation of charging parameters, thereby enhancing the overall security and reliability of the electric vehicle charging system.
[044] Advantageously, the present invention provides a system and a method for charging a battery pack of a vehicle with the help of a single charger unit. Hence, the present invention is efficient and reliable as compared to the existing systems. The present invention provides the single charger for efficiently charging the battery pack of the vehicle. The single charger unit is configured to charge at different output power ratings to meet the charging requirements and the needs of the user. Therefore, the present invention eliminates the issue of handling two chargers in the vehicle and is cost-efficient as well.
[045] The present invention provides an efficient and economical solution to charge the battery pack of the vehicle in two modes, including a low power level mode and a high power level mode by using an Alternating Current (AC) electric charger which can supply different output powers based on a user demand or available power supply at the plug point, and therefore, eliminates the need of two different power rated chargers. The present invention is efficient and reduces the overall cost.
[046] Further, the present invention prevents an unauthorized access by providing a secure connection between the VCU and the infotainment system. The charger unit enables the user to charge the vehicle at multiple power outputs without needing to use different chargers for different outputs. Further, the present invention helps in providing a safe way of charging at higher speeds by having control over the charger power demand. It also facilitates an inherent protection from an electrical failure due to higher wattage demand by the charger unit. The present invention also prevents the overloading of an input grid by correctly demanding power for the charger unit. Thus, the present invention improves the overall durability of the charger unit.
[047] Hence, the present invention provides an efficient and economical solution to charge the battery pack of the vehicle in two modes, including a low power supply mode and a high power supply mode, by using a single output power rated charger based on user demand or available power supply at the plug point, and eliminating need of two different chargers. Therefore, the system and method as provided in the invention enables the choice between charging at different power levels based on the preference of the user. The user who does not have the provision of higher wattage power points can operate the charger unit at lower demand. Hence, a single charger unit sufficiently charges the battery pack at different power levels.

Further, the claimed steps clearly bring an improvement in the functioning of the system itself as the claimed steps provide a technical solution to a technical problem.
[049] Furthermore, one or more computer-readable storage media may be utilized in implementing embodiments consistent with the present disclosure. A computer-readable storage medium refers to any type of physical memory on which information or data readable by a processor may be stored. Thus, a computer-readable storage medium may store instructions for execution by one or more processors, including instructions for causing the processor(s) to perform steps or stages consistent with the embodiments described herein. The term “computer-readable storage medium” should be understood to include tangible items and exclude carrier waves and transient signals, i.e., be non-transitory. Examples include random access memory (RAM), read-only memory (ROM), volatile memory, non-volatile memory, hard drives, CD ROMs, DVDs, flash drives, disks, and any other known physical storage media.
