⚙️ How the Tool Works

This calculator provides recommendations for two key components of any DC system:

• Recommended Fuse Size — Based on voltage, continuous current, and peak current. It also suggests slow-blow fuses for high inrush currents.
• Recommended Wire Gauge (AWG) — Calculates wire size to safely carry the current over the specified distance while keeping voltage drop under 3%.

📝 How to Use the Calculator

1. Enter System Voltage (V).
2. Enter Continuous Current (A) and Peak/Startup Current (A).
3. Enter Wire Length (m) from battery to load.
4. Select your Application Type (E-Bike, Scooter, Skateboard, Solar, BMS).
5. Click “Calculate” to see recommended fuse and wire gauge.
6. Optionally, Export to PDF for documentation or sharing.

💡 Why Use This Tool

• Safety First: Prevents overheating, fire, and damage from undersized fuses or wires.
• Performance Optimization: Correct wire gauge ensures minimal voltage drop for efficient operation.
• Time-Saving: No manual calculations needed for fuse sizing or AWG selection.
• Accurate & Realistic: Uses standard AWG tables factoring in continuous/peak currents, wire length, and system voltage.
• Documentation Ready: Export PDF for maintenance records or sharing with technicians.

🔍 Example

For a 52 V e-bike system with 20 A continuous current, 60 A peak current, and 1 m wire:

• Fuse: 70 A @ 60 V (slow-blow for motor inrush)
• Wire Gauge: AWG 0000

This ensures safety and reliable performance.

🧭 Summary

The Battery Fuse & Wire Gauge Calculator is essential for anyone working with e-bikes, scooters, or high-current DC systems. It provides accurate fuse and wire recommendations, enhancing safety, efficiency, and reliability while saving time and preventing costly mistakes.
