For a robust pack design:
- Cell Arrangement: Dry-fit cells to check planarity and compression requirements. Use torque wrenches for even pressure.
- Busbar Connections: Clean terminals with isopropyl alcohol, torque nuts to spec, and mark them to detect loosening.
- BMS Integration: Select a BMS with cell-level voltage monitoring and top-balancing during assembly. Validate protection thresholds against the datasheet.
- Thermal Management: Install temperature sensors and design enclosures with ventilation.
- Safety Compliance: Include pre-charge circuits, correct fusing, and documentation for audits.
- Testing: Run pilot packs through duty cycles, log performance data, and refine operating limits based on observations.
Standardize build steps and train teams on torque procedures to ensure consistency.
