A smart battery pack that uses a BMS and Configurable Logic Block (CLB) to detect faulty cells and bypass them in real time using relays. This ensures uninterrupted operation, boosts safety, and extends battery life. Ideal for EVs, drones, and renewable systems where uptime and reliability are critical.
⚙️ What It Does & Why It’s Cool
- ✅ Detects faulty or underperforming cells using BMS voltage monitoring.
- 🔄 Reconfigures the circuit in real-time by switching relays to bypass faulty cells, maintaining pack operation.
- 💡 Uses a CLB (Configurable Logic Block) for fast, deterministic relay control — no need for slow firmware loops.
- 🔋 Increases safety and reliability in multi-cell battery packs.
- 🧩 Modular design — can be scaled for any number of cells.
✨ Why It’s Cool:
- Fail-safe battery operation — perfect for mission-critical systems.
- CLB-based decision logic gives fast response without microcontroller overhead.
- No need to throw away the whole pack if one cell fails — just bypass it.

⚙️ How It Works
- Each cell is continuously monitored by a Battery Management System (BMS).
- If a cell is detected as underperforming or faulty, the BMS signals the CLB.
- The CLB triggers NO/NC relays to reroute current around the faulty cell, effectively bypassing it.
- The battery pack continues delivering power, skipping only the faulty section.
- The system is repeatable and scalable — one logic block per cell pair.
🔧 How the CLB Helped Our Design
The Configurable Logic Block (CLB) made the system fast, reliable, and firmware-independent. Unlike a microcontroller that might have software delays or get stuck, the CLB gives instant hardware-level decision-making. It allowed us to:
- Build custom fault response logic.
- Drive relays safely and instantly.
- Avoid complex firmware debugging.
By offloading control to the CLB, we made the system robust, real-time, and scalable — all essential for power-critical applications.
