# 🔋 Blockchain-Enabled Portable EV Charger
### Real-Time IoT Monitoring | Blockchain Ledger | Streamlit Visualization
---
## 📘 Introduction
This project presents a **Blockchain-Enabled Portable Electric Vehicle (EV) Charger** that ensures **secure, transparent, and real-time monitoring** of the charging process.
The system integrates **MATLAB/Simulink** for charger modeling and control, **Blockchain** for transaction security, and a **Streamlit-based web dashboard** for live visualization.
The goal is to create a **smart, portable, and tamper-proof EV charging system** capable of recording every energy transaction with transparency — essential for modern e-mobility infrastructure.
---
## ⚙️ System Overview
The project consists of three integrated layers:
| Layer | Description |
|--------|--------------|
| 🧩 **1. MATLAB/Simulink Layer** | Simulates the EV charging operation, logs real-time parameters such as voltage, current, energy, SOC, and cost. |
| 🔐 **2. Blockchain Layer** | Converts each charge session into a secure transaction, forming a blockchain ledger (`LiveLedger.csv`) with hash links to prevent tampering. |
| 💻 **3. Streamlit Dashboard** | Displays live charger metrics, plots, SOC %, energy, cost, and verifies blockchain integrity in real time. |
---
## 🧠 Key Features
- **Portable EV Charger Simulation** using MATLAB/Simulink.
- **Secure Blockchain Ledger** with SHA-256 transaction hashing.
- **Real-Time Dashboard** built with Streamlit for live monitoring.
- **SOC, Energy & Cost Calculation** based on dynamic charge parameters.
- **Cross-Platform**: Works on Windows, macOS, or Linux.
- **Auto-Refresh Visualization** with blockchain integrity validation.

## 🧾 Project Working
1. **Simulation**
- Run the `server_listener.m` and then the Simulink model of the portable EV charger.
- Then, run the `BasicData.m` to log basic parameters in the workspace.
- Key parameters (`Vout`, `Iout`, `SOC`, `Energy`, `Cost`) are logged to the workspace as Timeseries variables.
2. **Transaction Assembly**
- Run `transactions.m` to convert logs into blockchain-formatted data.
- The script generates:
- `Transactions.mat` → MATLAB structured data.
- Along this, open `addBlock.m` script and then run the file `build_blockchain_ledger.m`.
- `build_blockchain_ledger.m` creates ledger records.
- Finally, run the `create_csv_for_streamlit.m` file to successfully generate csv file containing dashboard parameters.
3. **Visualization**
- Launch the dashboard using:
```bash
python3 -m streamlit run ev_streamlit_dashboard.py
```
- View live metrics (SOC, power, cost) and blockchain status updates in the browser.
4. **Integrity Verification**
- Each ledger entry is validated via hash links (`PrevHash`, `Hash`).
- Any manual modification breaks integrity → shown as **"Blockchain Integrity FAILED"** on dashboard.
