EcoCharge

Inspiration

Public EV charging stations have 2-hour long queues and overload the city grid, while private home chargers sit empty. EcoCharge connects them into a peer-to-peer network—functioning like an "Airbnb for EV chargers."

What It Does & Real-World Example

Imagine an EV driver traveling with only 10% battery. Public chargers are packed, so they open EcoCharge:

1. Find Charger: Open the interactive map to locate an available nearby driveway charger.
2. Drive & Plug In: Route directly to the owner's spot and start charging.
3. Smart Payments: AI sets dynamic energy pricing while Web3 smart contracts release instant escrow payments without middleman fees.

How We Built It

• Frontend: React + Tailwind CSS (Interactive Map UI)
• Backend: Java Spring Boot (AI grid pricing & API management)
• Web3: Ethereum Testnet via Web3j/ethers.js (Decentralized auth & smart contract payments)

Challenges & Learnings

Connecting Spring Boot backends to asynchronous Web3 blockchains without UI lag, and using AI to balance smart city micro-grids.
