EV Charging Station Prototype with RFID Billing and Energy Metering

Approx. component budget: Rs. 8,000 - 14,000

Objective

Build a charging point that identifies the user, charges a small battery, measures energy and calculates a bill.

What you will build

A charging point model with a relay-controlled output, energy metering, RFID card authentication, a display, a safety interlock and a cloud dashboard recording each session.

Results you can expect

• Energy per session
• Billing accuracy vs reference meter
• Session log
• Protection tests (over-current, plug removal)
• Charge profile

What you will learn

EV charging basics, metering and billing, authentication and safety interlocks.

Tools and notes

ESP32, RFID reader, energy sensor, relay, small battery pack (not a vehicle). Use low voltage, a fuse and a safe battery enclosure.

Resume points from this project

• Built and tested EV Charging Station Prototype with RFID Billing and Energy Metering; objective: build a charging point that identifies the user, charges a small battery, measures energy and calculates a bill.
• Measured and analysed energy per session and billing accuracy vs reference meter; wrote the report and presented the results in a viva. Add your own numbers: [x].

Replace [x] with your own measured results. Write only what you really did.
