Description

[0001] “A RECHARGE SYSTEM FOR ELECTRIC VEHICLES”

[0002] FIELD OF THE INVENTION:

[0003] The present invention relates to a recharge system and more particularly relates to recharge system for electric vehicles.

[0004] BACKGROUND OF THE INVENTION:

[0005] In this 21stcentury, the depletion of fossil fuels is leading to an increase in demand for alternate renewable energy sources. As the supply of fossils fuels are at stake, the demand for the same is increasing rapidly. Due to rapid increase in demand for fossil fuels, the monetary value of the fossil fuels is at apex. Further, the Intergovernmental Panel on Climate Change (IPCC) has found that emissions from fossil fuels are the dominant cause of global warming.

[0006] In 2018, 89% of global CO2 emissions came from fossil fuels and industry. In one year, the average gas-powered car also produces four tons of carbon dioxide (CO2) as it slowly builds up in the atmosphere that causes global warming. Every liter of gasoline burned up in an auto engine sends over 4 kg of CO2, containing 1 kg of pure carbon, into the atmosphere.

[0007] One of the most economical and non-polluting sources of energy is electrical energy. Electric and hybrid vehicles may have significant emissions benefits over conventional vehicles. As per the growing demand, India is currently the third-largest market for Electric Vehicles (EVs) in the world, and the government is actively promoting the use of EVs through various initiatives. All-electric vehicles produce zero tailpipe emissions, and PHEVs (Plug-in Hybrid Electric Vehicles) produce no tailpipe emissions when operating in allelectric mode. HEV (Hybrid Electric Vehicles) emissions benefits vary by vehicle model and type of hybrid power system. Almost every electric vehicle has a Global Positioning System (GPS) or a Global System for Mobile Communications (GSM) installed in the electric vehicles.

[0008] The GSM is a standard developed by the European Telecommunications Standards Institute (ETSI) to describe the protocols for second-generation (2G) digital cellular networks used by mobile devices such as mobile phones and tablets. Further, pay per use vehicles exist in the art however, there is very less work on the recharge-based system for automobile industry. Some of the existing work is discussed as under.

[0009] United States Patent US8217772B2 to Morgan Gerald A and others is an automated geo-fence boundary configuration and activation system. The U.S Patent describes circular geo-fence or boundary, surrounding a geo-graphic area. The geofence is established based on current location of vehicle according to GPS data comprising latitude and longitude along with range or distance. The U.S Patent discloses a tamper proof onboard device for detection of geofencing violation. In the U.S Patent, the geofencing only alerts the user of crossing one particular boundary.

[0010] Another Chinese Patent Application CN 109409973A to JIANG Xin is a car rental system. The Chinese Patent Application describes a tracking unit for position detection of vehicle. The Chinese Patent Application further discloses a wireless location monitor for finding the real-time current location position of the vehicle. Further the Chinese Patent Application discloses registering unit, database unit, identification authenticating unit and an anti-theft alarm unit.

[0011] Yet another Chinese Patent Application CN 109272279 A to Lyu Zhenhui and othersis a kind of electric logistics tracking based on internet of things positioning cards. The Chinese Patent Application discloses electric logistics tracking based on loT positioning cards. It further describes a GPS system for position detection and real time tracking of vehicle. It also describes a geographic fence management that determines geo fence for vehicle monitoring. A Geography fence management service platform is constructed based on GIS electronic map.

[0012] There is a need of a system for driving electric vehicles as per the recharged kilometers. There is also a need of a system for halting electric vehicles upon crossing geofencing zones.

[0025] References in the specification to "one embodiment" or "an embodiment' means that a particular feature, structure, characteristic, or function described in connection with the embodiment is included in at least one embodiment of the invention. The appearances of the phrase “in one embodiment” in various places in the specification are not necessarily all referring to the same embodiment.

[0026] References in the specification to “preferred embodiment” means that a particular feature, structure, characteristic, or function described in detail thereby omitting known constructions and functions for clear description of the present invention.

[0027] The foregoing description of specific embodiments of the present invention has been presented for purposes of illustration and description. They are not intended to be exhaustive or to limit the present invention to the precise forms disclosed and obviously many modifications and variations are possible in light of the above teaching.

[0028] Referring to FIG. 1, a recharge system for electric vehicles 100 hereafter referred to as ‘system 100’ is described. The system 100 is preferably a recharge system that is positioned and configured inside any ‘electric vehicle’ referred hereinafter as ‘EV’, ‘vehicle’ to allow controlled maneuvering of the vehicle. In the present invention, the recharge system restricts the user of the EV to drive the vehicle only to a certain miles / kilometers for which the user has paid the tariff.

[0029] For example, if a user of EV has recharged for 10KM than the system 100 allows the user to drive the EV only up-to 10KM. The system 100 communicates with the user of the system through plurality of handheld devices 102 for example, mobile, tablet, electronic devices or the like. The user communicates with the system either through internet, GPS, GSM or the like.

[0030] The system 100 includes a primary controller 102 hereinafter referred to as ‘controller 102’ configured to restrict the maneuvering of the vehicle as per the recharged miles / kilometers. The primary controller 102 includes a progressive halting unit 134 that is configured to progressively halt the EV as per the instructions received from the controller 102. In accordance with the present invention, the primary controller 102 is positioned inside the EV and preferably positioned to bypass communication from accelerator.

[0031] In context of the present invention, an accelerator unit 124 is configured to accelerate the EV as per the user’s inputs. The accelerator unit 124 is connected to the primary controller 102, for modulating the vehicle acceleration based on user input and recharge data i.e., the kilometers or duration for which the user has paid the tariff. The system 100 includes a GSM unit 108 for connecting the system 100 with Cellular Network. The system 100 also includes a display unit 110 allowing the user to interact with the system 100. The system 100 communicates with a server 104 that stores historical data and supports additional functionalities like remote monitoring and advanced analytics.

[0032] The system 100 also includes a GPS (Global Positioning System) unit 128 for positioning the location of the EV. Further, the system 100 also includes a keypad unit 112 for interacting with the data displayed on display 110. The system 100 also includes a memory 126 for storing the data i.e., trip data, battery status, and telemetry records. The EV includes a battery unit 122 configured to power the vehicle, and the system 100. The primary controller 102 connects to the vehicle's powertrain, regulating its operation based on recharge data.

[0033] The EV includes a motor 118 and an EV Controller 120 configured for operating the EV. The system 100 includes a recharge module 132 that is configured to receive instructions from the user for recharging kilometers or duration to an EV upon receiving payment from the predefined user. The recharge module 132 limits vehicle operation strictly to the pre-paid duration or recharged kilometers / miles using a primary controller 102 with or without internet. The recharge module 132 facilitates users to pay for usage on a per-kilometer basis.

[0034] The recharge module 132 is configured to dynamically track usage and ensures the EV is only be operated within the prepaid distance. The recharge module 132 provides recharge options, through keypad, SMS, QR codes, or the like to provide flexibility irrespective of availability of connectivity. The recharge module 132 is configured to allowing users to request the last recharge code via the internet when SMS delivery fails. The recharge module 132 is configured to processes recharge and updates the kilometers or miles available for vehicle operation.

[0035] The primary controller 102 is configured to identify the geofencing regions for the driven EV. The controller 102 is configured with a geofencing and telematics module 136 that is devised to carve geographical regions in a particular area. The controller 102 is configured to define boundaries through the geofencing and telematics module 136 that processes data such as Global Positioning System (GPS), radio frequency identification (RFID), Wi-Fi or cellular data to define virtual geographic boundaries i.e., geofence. The geofencing and telematics module 136 is configured to identify the position of an EV driven inside and outside of the geofence.

[0036] In accordance with the present invention, the geofencing and telematics module 136 is further configured to store records details i.e., distance traveled, routes taken, and usage duration and also monitors battery health, charge levels, and alerts to users to critical statuses. Further, the geofencing and telematics module 136 is configured to monitor real-time speed and distance covered during operation, calculates the estimated range remaining based on wallet balance and recharged kilometers, providing predictive insights to the user. The geofencing and telematics module 136 is also configured to provide insights and detailed analytics on the monitored and stored data that aids in fleet management, optimize usage, and prevent misuse.

[0037] In accordance with the present invention, the geofencing and telematics module 136 is configured to check an EV within geofencing circle through, following condition:

[0038] “Sqrt [(LatC-LatG)A2 + (LongC-LongG)A2 ] < R”

[0039] Where,

[0040] Current Vehicle Location = LatC, LongC

[0041] Geofencing circle center = LatG, LonG

[0042] Radius of geofencing circle = R If above condition is true the EV is said to be in geofencing limit for that geofencing circle. Now say for vehicle A there are multiple geofencing circles configured on server 104. So, if the condition mentioned above is satisfied for at least one of the geofencing circles then EV is said to be within allotted geofencing limit. If condition specified above is not true for any of the geofencing circles then it’ s concluded that EV is out of geofencing limit.

[0043] Now when the above geofencing related decision is taken by the controller 102 locally i.e., in absence of internet connectivity, it’s termed as offline geofencing. In such situations system 100 immediately turns off EV controller 120 or gradually slows down speed to finally disable the EV. When the above geofencing related decision happens at server side, it’s termed as online geofencing, and the server 104 sends signal to controller 102 through API to initiate geofencing slowing down sequence. Before turning off the vehicle, the driver is notified with audio visual alarms in advance for him to get sufficient time to pull over vehicle and park it on roadside.

[0044] In context of the present invention, the controller 102 is configured to restrict maneuvering of the electric vehicle based on the pre-paid duration or recharged miles / kilometers. In accordance with the present invention, the controller 102 is positioned between the accelerator 124 of an EV and the motor controller 118 of an EV. The controller 102 is configured to read the driver’s acceleration inputs and modulate EV vehicle movement accordingly. The controller 102 further processes the recharge data to compute the allowable distance or usage time as per the recharged amount / kilometers. The controller 102 receives the recharge data from the recharge module 132 to compute the allowable distance or usage time. The controller 102 includes a modulation unit 109 that is invoked for translating recharged data into a proportional duration or distance that the vehicle may travel. The modulation unit 109 ensures controlled operation of the motor 118 as per the recharge or geofencing restrictions. Further, the controller 102 is configured to calculate the distance travelled by an EV through two methods. In a first method, the diameter of a vehicle wheel is identified along with the revolutions per minute (rpm). Further, the distance travelled by the vehicle is calculated as follows”

[0045] “Distance in KM = pi x (diameter of vehicle in meter x 1000) x (rpm x 60)”

[0046] In accordance with the present invention, the controller is configured with the second method for calculating the distance travelled by an EV. In this second method the controller 102 is configured to identify Latitude and Longitude of EV location and are continuously sent by EV to the server 104. Further, through the received multiple Latitude and Longitude data distance travelled between two points is calculated mentioned as under:

[0047] “Distance, d = 3963.0 * arccos[(sin(latl) * sin(lat2)) + cos(latl) * cos(lat2) * cos(long2 - longl)]”.

[0048] It is to be noted that the controller 102 is configured to invoke the first method preferably in absence of internet connectivity whereas the second method is preferably invoked for calculating distance based on latitude and longitude through the internet connectivity. Upon identification, the primary controller 102 invokes the progressive halting unit 134 that work in tandem with the geofencing and telematics module 136 to identify the EV location crossing geofence and halts the EV through the progressive halting unit 134. The progressive halting unit 134 is configured to halt the EV upon crossing the geofence irrespective of internet connectivity.

[0049] The progressive halting unit 134 reads the recharge data from the recharge module 132 and is configured to calculate the remaining kilometers or time for validity of the recharge. The progressive halting unit 134 is configured to initiate a gradual reduction in speed such that the EV is stopped within 1 to 5 mins of depleting the recharge kilometers. In case the EV crosses the geofence areas the progressive halting unit 134 gradually halts EV within 1-2 KMs near the geofence. Eventually, the vehicle comes to a complete stop if no additional recharge is made Furthermore, the user may extend the range of driving by recharging the driving kilometers by just sending an SMS or the like. The controller 102 is configured to activate the EV once it reenters the within the geofence.

[0050] The system 100 also includes a notification unit 114 for alerting the user. The notification unit 114 is configured to provide real-time alerts through messages, email, or audio-visual cues for recharge depletion, geofence boundary crossings, battery status warnings. The system 100 includes a recharge module 132 for generation of tokens. The recharge module 132 is configured to receive a recharge token either from the display unit 110 or from the GSM unit 108. The recharge module 132 is configured on the primary controller 102 for communicating the recharge data to and from the user with the primary controller 102. The recharge module 132 is invoked to recharge additional kilometers through SMS, QR code scanning, or internet-based recharge, through the primary controller 102 to process and extend the recharge kilometers to existing validity of duration or number of kilometers.

[0051] The system 100 also includes a server 104 for storing the data and communicating the stored data to the primary controller 102. Further, the primary controller 102 includes a modulation unit 109 for modulating pulses. Moreover, the primary controller 102 also includes at least three UARTs (Universal Asynchronous Transmitter and Receiver) 116 for exchanging serial data between two devices. The GSM unit 108 and the GPS unit 128 are connected with the UARTs 116.

[0052] In accordance with the present invention, the accelerator unit 124 connects with the ADC (Analog to Digital Converter) of the primary controller 102 for exchanging data. Further, the memory 126, the display unit 110, the keypad 112 and the notification unit 114 connect and communicate with the primary controller 102 for exchanging data. Further, the EV controller 120 is connected with the primary controller 102 through the modulation unit 109. Moreover, the battery unit 122 and the Motor 118 is connected with the EV controller 120. The primary controller 102 is connected with at least three UARTs 116 for exchanging data with other devices.

[0053] In context of the present invention, all the auxiliary modules or boards are connected to the primary controller 102. In accordance with the present invention, the modulation unit 109 is configured to activate the motor 118 for predefined amount of time proportionate to the recharge amount. Further, the recharge module 132 communicates with the primary controller 102 to drive the EV only as per recharged amount. In accordance with the present invention the recharge notification is received to the system 100 by entering the received recharge code from the system 100 through the keypad 112. The keypad unit 112 allows user to interact with the system 100, check metrics, and input recharge codes.

[0054] Further, the system 100 is configured to receive the token amount by scanning the QR Code. The recharge module 132 processes the data on the primary controller 102 such that the primary controller 102 is configured to update the recharged kilometres / miles in the system 100. In accordance with the present invention, the controller 102 gradually halts the vehicle once said vehicle is near to consume the recharged kilometres irrespective of the internet connectivity.

[0055] Now referring to FIG. 2, an operational flow of progressive halting of an Electric Vehicle is described hereinafter. In an initial step 205 the EV transmits location data i.e., latitude and longitude to the server 104 every 10-30 seconds through GPS module 128 and GSM module 108. In a next step 210, the server 104 is configured to check the position of EV and evaluates whether the vehicle's location is inside the geofence regions. In a next step 215, the server 104 identifies the location of EV whether EV is inside or outside of geofence. In a next step 250, the EV may be driven until the recharge is depleted.

[0056] In an alternative situation the control is transferred towards step 220 for triggering the progressive halting of EV either online or offline. In this step 220, the controller 102 is invoked to progressively halt in an offline manner in absence of internet. Contrarily, the server 104 is invoked to progressively halt in an online manner in presence of internet. Accordingly, a next step 225 is invoked to halt the vehicle progressively through the controller 102 through an offline geofencing method or a next step 230 is invoked to halt the vehicle progressively through the server 104 through an online geofencing method.

[0057] In a next step 235, the EV controller 120 is gradually disabled by invoking the progressive halting unit 134 by the controller 102. Simultaneously, in a next step 240, the user is notified through audio-visual alerts, giving them time to pull over and park safely. In a final step 245, as configured, the system 100 ensures the vehicle comes to a complete halt, either gradually or immediately, based on user preference.

[0058] Referring to FIG. 3, an operational flow of configuring a controller 102 inside an EV vehicle is described hereinafter. In an initial step 305, the primary controller 102 is initialized and the vehicle begins operation, with the primary controller 102 actively monitoring inputs. In a next step 310, the primary controller 102 intercepts acceleration signals from the driver through the accelerator unit 124, regulates motor 118 and receives responses based on remaining validity or recharge by accessing the recharge module 132. In a next step 315, the controller 102 calculates the remaining distance using the first method or the second method as specified earlier.

[0059] In a next step 320, the validity is checked based on the pre-paid recharge and usage. The control is transferred towards step 325 for progressively halting the EV through the progressive halting unit 134 upon exhausting the validity or entering outside the geofence. Contrarily in a next step 330, upon detecting the active validity of recharge the vehicle is modulated and gradually stopped upon utilizing of recharge validity.

[0060] In a next step 335, the EV controller 120 is gradually disabled by invoking the progressive halting unit 134 by the controller 102. Simultaneously, in a next step 340, the user is notified through audio-visual alerts, giving them time to pull over and park safely. In a final step 345, the system 100 facilitates to recharge kilometres or time through methods like SMS, QR code scanning, or internet. In this step 345, once a recharge is processed, the validity is extended, allowing the vehicle to resume normal operation. In this step 345 the controller resumes monitoring accelerator inputs and the process restarts.

[0061] In operation initially, the user of the system 100 initializes the modules and controllers. Further, the system 100, verifies the recharge value i.e., a range of miles / kilometres a particular EV is driven proportionate to the recharge amount. The primary controller 102 operates the EV as per the recharge value. Further, the primary controller 102 is configured to notify the user either through, message, email, audio-visual notification or all of the above. The primary controller 102 identifies the geofencing of the EV. Once EV crosses the geofence it gradually slows down before a complete halt irrespective of internet connectivity. The EV is again maneuvered once the user enters inside the boundary of geofence.

[0062] The system 100 advantageously drives the vehicle as per recharged amount. The system 100 allows the user to track the vehicle. The system 100 also alerts the user before depleting the recharge amount. Further, the system 100 controls the vehicle once it crosses the geofence. Moreover, the system 100 work irrespective of internet connectivity.

[0063] The embodiments were chosen and described in order to best explain the principles of the present invention and its practical application, to thereby enable others, skilled in the art to best utilize the present invention and various embodiments with various modifications as are suited to the particular use contemplated.

[0064] It is understood that various omission and substitutions of equivalents are contemplated as circumstance may suggest or render expedient, but such are intended to cover the application or implementation without departing from the scope of the present invention.
