Despite the AC voltage ranging from 160V to 270V, the output of the regulator remains stable at 5V, ensuring consistent performance even with input voltage fluctuations from around 8V to 15V. A 10F 20 tiny electrolytic capacitor is utilized for additional noise filtering of the regulated 5V DC output. To indicate the presence of a 5V power source, anLED is connected in series with a 330-ohm current-limitingresistor from the 5V point to ground.

FLOW CHART FOR LCD

POWER SUPPLY UNIT

An electrical device or circuit known as a power supply is used to transform an input voltage from a power source intoa steady outputvoltagethat may be utilisedtopowervariouselectronicdevicesorcircuits. Atransformer,rectifier,andvoltageregulatorareafew ofthepartsthatmakeupastandardpowersupply.

An element that is used to step-up or step-down the input voltage to a desired level is a transformer. It consists of a shared magnetic core and two wire coils, known as the primary and secondary windings. When an AC voltage is applied to the primary winding, it generates a magnetic field in the core. This magnetic field then induces a voltage in thesecondary winding. By adjusting the number of turns in theprimary and secondarywindings,thetransformercaneither

RECTIFIER

The rectifier is responsible for converting the output from the transformer, which is in AC form, into pulsating DC. In this project, a bridge rectifier is used due to its advantages such as excellent stability and full-wave rectification, as compared to half-wave or full-waverectifiers.

A voltage regulator can also protect against overvoltage or undervoltage conditions, which canoccurinthehome's powergridduetovarious factors such as power surges, grid fluctuations, or load changes. Overvoltage or undervoltage can potentially damage the wireless charging system or the EV's battery. A voltage regulator can monitor the incoming voltageandregulateitto ensure it stays within the safe operating range. Wireless charging systems for EVs can be designed to support gridconnection,whichallowsthem tonotonlychargetheEVbutalsotofeedexcessenergyback into the home's power grid. A voltage regulator can help facilitate this bidirectional power flow, regulating the voltagetoensurecompatibilitywiththehome's power grid and enabling efficient grid connection. We use an LM7805 voltage regulator IC to provide a 5 volt power supply.

Wireless charging systems for EVs typically use a combination of coils, resonant circuits, and power electronics to transfer energy wirelessly from a chargingstationtothevehicle'sonboardcharger,whichthen charges the EV's battery. The primary coil, located in the chargingstation,isconnectedtoanACpowersource,while

In anEV wireless charging system that uses a home as a chargingstation, The house's roof has solar panels that can be utilised to produce electricity. Direct current (DC) electricity from the solar panels is routed to an inverter, which transforms it into alternating current (AC) electricity that may be used to power the wireless charging system. The AC electricity is then sent to a charging station, which is installed in the parking of the home.

The electricity from the charging station is transferredto theEV'sbatterybythewirelesschargingtechnologyusing a charging coil that is linked to the charging station. Magneticinductionisusedbythechargingcoiltogenerate amagneticfieldthatwirelesslytransmitselectricitytothe EV battery.

WIND SOURCE

Electric vehicles (EVs) uses wind energy instead of solar energy in any of climate changes, but it would require somechangesinthecharginginfrastructure.

To use wind energy for wireless charging, we need a wind

turbinetogenerateelectricity.The windturbinewould need to be connected to a battery storage system, which wouldstore the electricity until it's needed for charging theEVs.When an EV drives over the wireless charging pad, thereceiver on the EV would communicate with the charging station to initiate the charging process. Thecharging station would then draw electricity from thebattery storagesystempowered by the wind turbine, and wirelessly transmit it tothe receiver on the EV to chargethebattery.

To use a home as a charging station, you would need to install a wireless charging pad on your driveway or garagefloor. The wind turbine and battery storage system could be installed on your property as well, or could be connectedtoanearbywindfarmifavailable.

The working of an inverter with volts is explained as follows: The voltage from the solar panels or battery is typically in the range of 12V to 48V DC, depending on the system's configuration. The inverter takes the DC voltage as input and converts it into AC voltage, typically at 110V or 220V,dependingonthecountry'selectricalstandard.

WORKING OF SOFTWARE

The Arduino runs the Arduino IDE software. An electric vehicle (EV) wireless charging system’s numerous component can be managed using the Arduino microcontrollerplatform.

Arduino software could be used in a wireless charging systemthatusesahomeasachargingstation.

ThewirelesschargingcoilwouldbeconnectedtoanArduino board, which would control the charging process. The ArduinoboardwouldbeprogrammedtodetectwhenanEV is parked over the charging coil. This could be done using sensorsorothermeansofdetectingthepresenceoftheEV. Once the Arduino board detects the presence of the EV, it would initiate the charging process. This could involve activating the electromagnetic field that transfers energy wirelesslyfromthechargingpadtotheEV'sbattery.

TheArduinoboardwouldmonitorthechargingprocessto ensurethattheEV'sbatteryischargedsafelyandefficiently. Itcouldadjustthechargingrateorvoltageifneededtoavoid damaging the battery. Once the EV's battery is fully charged, theArduinoboardwouldstopthechargingprocess.

TheArduino board could also be used to monitor the energy consumption of the charging system and to send data to a monitoring system that could be accessed remotely. In addition to controlling the charging process, Arduino softwarecouldbeusedtoprovideadditionalfunctionalityto thewirelesschargingsystem.Forexample,itcouldbeused tocontrolthelightingorventilationinthechargingstation, or to communicate with other smart home systems.

Using the home as a charging station has the potential to simplify the charging process. There are several benefits to using wireless charging at home, including the ability to charge without having to physicallypluginthevehicle,reducingwearandtearonthe chargingport,andpotentiallyincreasingthelifespanofthe vehicle'sbattery.Additionally,homewirelesschargingcan reducetheneedforpubliccharginginfrastructure.However, therearealsosomechallengesthatneedtobeaddressedfor widespread adoption of wireless charging technology, includingtheneedforstandardizationandinteroperability between different charging systems, as well as concerns aboutsafetyandefficiency.
