Wireless EV Charge Point Kit with ESP32 + LED
Build a Wireless EV Charge Point with ESP32, RFID and Cloud Billing
Every part needed, pre-tested for compatibility, with an AI build companion trained on this exact project. Shipped from Bengaluru in 3-5 days.
Turn a DIN rail enclosure into a working prototype of a wireless charging station: measure real AC power with the ACS712 current sensor and ZMPT101B voltage transformer, gate every charge session with tap-to-start RFID cards, and push kilowatt-hour logs to the cloud over WiFi. This kit gives you the exact circuit and firmware flow to recreate a billing-grade EV charge point for your capstone project, hackathon demo, or smart grid exploration.
What You'll Build
A compact, wall-mountable unit that reads voltage and current simultaneously, computes true RMS power, and displays live kW and session cost on a crisp OLED. Tapping an RFID card starts a timestamped session; a second tap ends it and writes duration and total kWh to a microSD file while uploading the summary to a cloud dashboard like ThingSpeak or Blynk.
What You'll Learn
- AC power measurement using RMS calculation with ACS712 and ZMPT101B
- RFID-based access control and session gating with MFRC522
- Time-stamped data logging using DS3231 RTC and microSD
- Cloud data posting via ESP32 WiFi and MQTT/HTTP protocols

Who This Kit Is For
The Wireless EV Charge Point Kit is built for B.Tech ECE/EEE final-year students tackling energy metering projects, Smart India Hackathon teams prototyping smart charging solutions, and ATL Tinkering Lab mentors guiding advanced IoT prototypes. It assumes familiarity with Arduino IDE, basic AC circuits, and soldering — a powerful step-up from simple sensor kits.
Built and Backed by Compoden
Every Compoden kit ships with an AI build companion trained on this exact project — accessible via a QR code on the box, with WhatsApp and email backup. We've spent 10 years building projects for makers, schools, and institutions across India. If a part fails because of a manufacturing defect, replace it free within 7 days.
What if I get stuck during the build?
Scan the QR code on the box to open the AI companion trained on this exact circuit and firmware; you can also send a WhatsApp photo of your wiring to our support team and we'll help debug.
Does this kit require a cloud subscription?
No — the ESP32 code can post to free platforms like ThingSpeak or Blynk with a personal API key. The kit includes sample sketches for both.
Can I charge an actual EV with this prototype?
This kit is for educational prototyping. The ACS712 handles up to 20A, but always use a low-voltage AC source for safe testing.
What software and IDEs are needed?
Arduino IDE with ESP32 board package; all required libraries are listed in the build guide, and the AI companion will walk you through installation.
ACS712 + ZMPT101B measure EV charge power. RFID gates session start. ESP32 posts kWh to cloud billing.
