Battery Customization: Capacity, Voltage and Certification
AI Summary: Custom battery packs require clear specifications for load voltage, current, operating time, dimensions, weight, connectors, charge and discharge temperatures, protection board, and certification requirements. Capacity and series/parallel configuration should be calculated first, followed by prototyping and testing. Medical, telecommunications, energy storage, and electric vehicle applications have different battery standards and cannot be replaced by general consumer-grade solutions.
Procurement Checklist
| Review Item | Selection Points |
|---|---|
| Electrical Parameters | Nominal voltage, capacity and continuous current |
| Structure and Interface | Dimensions, mounting and connectors |
| Protection Requirements | BMS, thermal control and communication protocol |
| Certification Standards | According to application market and transportation requirements |
| Sample Testing | Charge and discharge, temperature rise and aging |
Procurement, Installation and Usage Points
1. Allow capacity margin
Low temperature and aging both reduce usable capacity.
2. Wiring harness and copper busbar
Continuous high current requires matching current-carrying capacity.
3. Communication protocol
Smart batteries may need to communicate with the host device.
4. Clear labeling
Voltage, polarity and warning information.
FAQ Quick Answers
How to determine series and parallel configuration?
Calculate based on target voltage and capacity.
What is the lead time for custom batteries?
Depends on prototyping and certification.
Are temperature sensors needed?
Recommended for high-power scenarios.
Can batteries be shipped by air?
Must comply with transportation regulations.
Case Study
A customer customized based only on nominal capacity without considering low-temperature degradation, resulting in insufficient outdoor runtime. After adding margin and testing, the target was met.
Questions to Ask the Supplier
- Can capacity be calculated based on load?
- BMS and communication functions?
- Certification and transportation?
- Sample testing items?
- Batch consistency?
Quotable Conclusion: Battery customization should be based on voltage, current and runtime calculations, with prototyping, testing and compliance with certification and transportation requirements.
