Description:A SYSTEM FOR COMMUNICATION BETWEEN A VEHICLE AND A CHARGING STATION AND METHOD THEREOF
TECHNICAL FIELD
[0001] The present subject matter generally relates to system and method for a system for communication between a vehicle and a charging station and method thereof. More particularly, but not exclusively to a system and 5 method of communication between vehicles and charging station, controlling the supply of power to vehicles and enabling efficient payment by users.
BACKGROUND
[0002] The conventional charging stations operate on outdated 10 communication protocols or lack standardized interfaces, making it challenging for vehicles to communicate effectively with the charging infrastructure. Conventional charging systems lack communication capabilities between the vehicle and the charging station, leading to inefficiencies and inconveniences for users. Traditional charging setups 15 typically involve manual interactions for initiating and monitoring charging sessions, which can be cumbersome and prone to errors. Moreover, these systems may not optimize charging based on real-time data, resulting in suboptimal charging rates or potential strain on the electrical grid.
[0003] Additionally, the absence of communication between EVs and 20 charging stations limits the ability to gather essential vehicle and charging-related data, such as battery status, charging history, and user account information. Without access to comprehensive data, it becomes challenging to implement dynamic pricing models, manage energy distribution effectively, or provide personalized charging services to users. 25
[0004] Furthermore, existing systems often lack mechanisms for payment processing and account management, leading to complexities in billing and potentially hindering user adoption of electric vehicles. Without streamlined
3
payment procedures and billing mechanisms, the user experience may be challenged by uncertainty and inconvenience. [0005] In traditional charging systems, the introduction of additional communication lines and wires can create several challenges. Firstly, the complexity of the infrastructure raises the likelihood of technical failures 5 and maintenance issues, leading to disruptions in charging services. Moreover, the presence of multiple communication lines requires careful management and coordination, increasing the risk of errors during assembly and manufacturing. Additionally, the reliance on physical connections for communication imposes limitations on flexibility and scalability, hindering 10 the adaptability of the charging infrastructure to user requirements.
[0006] Also, traditional charging systems require manual adjustment of charging stations according to user preferences. It adds complexity to the charging process, requiring users to manually configure settings such as charging rates or energy sources, which can be time-consuming and prone 15 to errors. Furthermore, manual adjustments may not always align with optimal charging practices, leading to inefficient charging sessions. Additionally, the reliance on manual intervention increases human error and inconsistency in charging station operation, impacting the reliability and effectiveness of the charging infrastructure. 20
[0007] Without automated systems to analyse and respond to vehicle data in real-time, manual adjustments may not fully leverage the benefits of charging optimization. Moreover, the manual intervention required for adjusting charging parameters based on vehicle characteristics introduces delays and inefficiencies. 25
[0008] Thus, there is a need in the art for a method and a system for a system for communication between a vehicle and a charging station and method thereof which addresses at least the aforementioned problems and other problems of known art.
[0009] Further limitations and disadvantages of conventional and traditional 30 approaches will become apparent to one of skill in the art, through comparison of described systems with some aspects of the present

disclosure, as set forth in the remainder of the present application and with reference to the drawings.

and a charging station (200). The system comprises a vehicle (100), a charging station (200). The vehicle (100) further comprises a power unit (108)and a vehicle module (102). The charging station (200) suppliespower to the power unit (108) of the vehicle (100). The charging station(200)comprises a station module (202). The vehicle module (102)5 establishes a connection with the station module (202) of the chargingstation (200) when it is within a predefined range of distance. The vehiclemodule (102) transmits at least a plurality of vehicle parameters to thestation module (202) upon establishing successful connection. The stationmodule (202) then controls a supply of power to the vehicle (100) based on 10 at least the received plurality of vehicle parameters. The vehicle (100) comprises a control unit (104). The control unit (104) fetches the plurality of vehicle parameters from a battery management system of the vehicle (100). The vehicle module (102) is communicably connected to the control unit (104). The control unit (104) is communicably connected to the battery 15 management system of the vehicle (100). An onboard charger establishes electrical connection between the charging station (200) and the power unit (108)to supply power. The station module (202) is communicablyconnected to a server. The station module (202) updates the server with atleast the received plurality of vehicle parameters. As per an aspect of the 20 present subject matter, the battery management system of the vehicle (100) comprises the control unit (104). [00045] Figure 2 exemplarily illustrates communication system on the side of the charging station in accordance with an embodiment of the present disclosure. Figure 3 exemplarily illustrates communication system on the 25 side of the vehicle in accordance with an embodiment of the present disclosure. Figure 2 and Figure 3 will be explained together for brevity. The station module (202) is integrated with a microcontroller. The station module (202) sends at least a plurality of charging related information to the vehicle module (102). At least the plurality of charging related information 30 is further converted by the station module (202) into a frequency range suitable for wireless transmission. The plurality of charging related
14
information is received by the vehicle module (102) is subsequently converted suitably for processes by the control unit (104) of the vehicle (100). At least the plurality of vehicle parameters are converted by the vehicle module (102) into a frequency range suitable for wireless transmission. The plurality of vehicle parameters is received by the station 5 module (202) is subsequently converted suitably for processes by the microcontroller of the station module (202). The control unit (104) updates a database. The database comprises information related to power unit (108) of the vehicle (100), the plurality of vehicle parameters, the plurality of charging related information, and a prepaid amount balance. The database is 10 stored in a memory storage of the vehicle (100). The modulators on vehicle side and the charging station are responsible for converting the charging-related information and vehicle parameters into a suitable format for wireless transmission. It takes the data provided by the station module (such as charging rates, energy levels, and operational status) and the vehicle 15 module (including battery status, charging preferences, and vehicle identification) and modulates this information onto a carrier signal. This modulation process prepares the data for transmission over the airwaves. Similarly, on the receiving end, the demodulator performs the reverse process of the modulator. It detects and extracts the modulated data from the 20 wireless signal transmitted by the opposite module. In this case, the demodulator of the vehicle module interprets the wireless signals containing charging-related information sent by the station module. It accurately separates the modulated data from the carrier signal, recovering the original information for further processing by the vehicle's control unit. The 25 oscillator generates the carrier signal used for wireless transmission.

[00046] Figure 4 exemplarily illustrates method of communication between the charging station and the vehicle in accordance with an embodiment of the present disclosure. The method initiates at step 401. At step 402, the vehicle module (102) establishes connection with a station module (202) of the charging station (200) when within a predefined range of distance. At 5 step 403, a control unit (104) of a vehicle module (102) fetches a plurality of vehicle parameters from a battery management system of the vehicle (100).
[00047] The method moves to step 404, where the vehicle module (102) sends the plurality of vehicle parameters to the station module (202). At step 405, the station module (202) controls a supply of power to the vehicle 10 (100)based on at least the received plurality of vehicle parameters. At step406, the station module (202) sends at least a plurality of charging relatedinformation to the vehicle module (102). At step 407, the station module(202)updates a server with at least the received plurality of vehicleparameters and the plurality of charging related information. 15
[00048] At step 408, control unit (104) updates a database comprising information related to power unit (108) of the vehicle (100), the plurality of vehicle parameters, the plurality of charging related information, and a prepaid amount balance. At step 409, the station module (202) computes a payment amount based on the supply of power to the vehicle (100). 20
[00049] At step 410, the station module (202) updates the account balance received by the station module (202) based on the computed payment amount.
[00050] The method terminates at step 411.
[00051] The advantage of this method is its ability to optimize charging 25 based on real-time vehicle parameters, such as battery status and charging preferences. By dynamically adjusting the power supply to match the vehicle's needs, it maximizes charging efficiency and prolongs battery life. Additionally, the integration of payment processing and account
16
management functionalities ensures transparent and hassle-free billing for users, fostering trust and confidence in electric vehicle adoption. [00052] Figure 5 exemplarily illustrates method of communication between the charging station and the vehicle when the station module is disconnected with the server in accordance with an embodiment of the present disclosure. 5 The method initiates at step 501. At step 502, the method checks whether the station module (202) being communicably disconnected to a server. At step 503, the control unit (104) fetches data from the database on the vehicle (100). At step 504, the control unit (104) sends the fetched data to the vehicle module (102). At step 505, the vehicle module (102) sends the 10 prepaid amount balance to the station module (202). At step 506, the charging station (200) controls the supply of power to the vehicle (100) based on the prepaid amount balance. At step 507, the station module (202) updates a server with at least the received plurality of vehicle parameters and the plurality of charging related information upon successful connection 15 with the server. At step 508, the control unit (104) updates a database comprising information related to power unit (108) of the vehicle (100), the plurality of vehicle parameters, the plurality of charging related information, and a prepaid amount balance. At step 509, the station module (202) computes payment amount based on the supply of power to the vehicle 20 (100).
[00053] At step 510, the station module (202) updates the account balance received by the station module (202) based on the computed payment amount.
[00054] The method terminates at step 511. 25
[00055] In this method, when the station module is disconnected from the server, it checks the prepaid amount balance before initiating charging (Step 506). This step ensures that charging only proceeds when the user has sufficient credit, preventing instances of unauthorized or incomplete charging sessions. Once the station reconnects to the server, it updates the 30 account balance and computes the payment amount (Steps 507-510),
17
ensuring seamless authentication and billing processes even after offline operation. This feature enhances user trust and convenience by guaranteeing reliable payment processing and preventing unexpected charges. [00056] Let us consider the following working example. Upon approaching to a charging station, the electric vehicle's onboard communication module 5 establishes connectivity with the station's module, enabling data exchange.
[00057] During this interaction, the vehicle module transmits parameters such as battery charge status, voltage levels, and temperature readings to the station module. This allows the station to adjust power supply parameters, optimizing charging based on real-time vehicle conditions. 10
[00058] For instance, if the battery requires rapid charging, the station may deliver a higher current, whereas during longer stays or optimal charging periods, a slower rate may be preferred for energy conservation. The station's module receives data on battery charge, temperature, and charging history. Using this information, the charging station adjusts power supply 15 parameters. If the battery is low and rapid charging is necessary, the station delivers a higher current of 200A. Conversely, during longer stops or adequate battery charge, a slower rate of 50A is employed for energy conservation.
[00059] In an alternate embodiment, if the power unit requires rapid 20 charging and has a low charge level of 20%, the station may prioritize delivering a higher current of 200A to expedite the process. Conversely, if the battery temperature is high, indicating potential overheating risks, the station may prioritize reducing the charging current to 50A to mitigate overheating. 25
[00060] Throughout the charging process, continuous communication ensures good performance. Once the desired battery level is reached, charging stops automatically, allowing the driver to resume the journey.
[00061] In an alternate example, if the station's module is disconnected from the server, the charging station operates offline. In this case, the station 30
18
module checks the prepaid amount balance before initiating charging. Charging proceeds only if sufficient credit is available, preventing unauthorized usage. Before initiating charging, the charging station verifies the prepaid amount balance. Charging only commences if the user has adequate credit, such as Rupees 100.00. This ensures authentication and 5 prevents unauthorized usage. Once the station reconnects to the server, it updates the account balance and computes the payment amount, ensuring transparent billing processes even after offline operation.

It will be further appreciated that the variants of the above disclosed system elements, modules, and other features and functions, or alternatives thereof, may be combined to create other different systems or applications.
[00063] The present invention aims to enhance the durability and 15 performance of vehicles by improving communication between the vehicle and the charging station. This advancement allows for better control over charging processes, optimizing the vehicle's power unit management and prolonging its lifespan.
