Electrical viva questions on this project
What is the aim of the Solar Wireless Electric Vehicle Charging System project?
A solar-powered wireless charging system for electric vehicles. Coils embedded in the road transfer power to a coil under the vehicle, demonstrating charging while driving.
Explain the working of your project in short.
Solar panel and Rechargeable battery supply the circuit; a regulator gives the controller and sensors a steady 5 V. The ATmega328P microcontroller with base board is the brain of the circuit: it samples the sensors, compares readings with set limits and switches the outputs. The 16×2 LCD with I2C adapter shows readings, status and messages to the user.
Why is a microcontroller used in this project?
A microcontroller combines a CPU, memory and I/O pins on one chip, so a single low-cost IC can read sensors, make decisions in code and control loads without a computer.
Why is an I2C adapter used with the LCD?
It reduces the wiring from about 10 pins to 2 (SDA and SCL), leaving more controller pins free for sensors.
What is the efficiency of a typical solar panel?
Commercial polycrystalline panels convert about 15–17% and monocrystalline about 18–22% of sunlight into electricity. Output depends on sunlight, angle and temperature.
How do you calculate battery backup time?
Backup time (hours) ≈ battery capacity (Ah) × voltage × 0.8 efficiency ÷ load power (W). For example, 12 V 7 Ah at 20 W gives about 3.3 hours.
How is 230 V AC converted to 5 V DC for the circuit?
A transformer steps down the voltage, a bridge rectifier converts AC to pulsating DC, a capacitor smooths it and a 7805 regulator gives a steady 5 V.
How did you calculate the power rating of your system?
Using P = V × I for each load, adding a margin of 20 to 25%. The solar panel is sized from the daily energy need divided by about 5 peak sun hours in India. Battery capacity is the energy needed per day divided by the battery voltage and allowable depth of discharge.
What protection have you provided in the circuit?
A fuse against short circuit, relays or optocouplers to isolate the control side from the power side, flyback diodes across inductive loads such as relays and motors, and software limits that cut off on over-current or over-voltage.
What is the efficiency of your system and how did you measure it?
Efficiency = output power ÷ input power × 100. We measured input and output voltage and current with a multimeter at different loads and tabulated the results in the report.
Explain the block diagram of your project.
The input section senses the real-world quantity, the ATmega328P microcontroller with base board processes it according to the program, and the output section displays the result and drives the actuators. The power supply section feeds every block.
Is your system open-loop or closed-loop?
Mainly open-loop: the controller runs the actuators for a set time or number of steps. Adding a sensor for feedback would make it closed-loop and more accurate.
