- Capacity test
- 温度試験
- Protection function test
Product Verification
The battery pack is tested with the customer’s equipment to confirm:
- Installation compatibility
- Operating performance
- 通信機能
Prototype validation helps identify potential design improvements before mass production.
6. Mechanical Design and Product Integration
Battery pack design is not only about electrical performance.
The physical structure must match the equipment.
OEM manufacturers support:
- Battery enclosure design
- Mounting structure
- Waterproof design
- Cable arrangement
- Connector integration
Common enclosure options include:
- Plastic housing
- Aluminum alloy housing
- Metal enclosure
For outdoor applications, manufacturers may design battery packs with protection levels such as IP65, IP67, or IP68.
7. Certification and Compliance Support
Lithium battery products need to meet transportation and market requirements.
OEM battery manufacturers can assist customers with certification preparation.
一般的な資格には以下のようなものがある:
Transportation Requirements
- UN38.3
- MSDS
International Safety Standards
- IEC 62133-2
- CE
- RoHS
Light Electric Vehicle Applications
- UL2271
Certification requirements should be considered during product development rather than after production.
8. Quality Control During Manufacturing
A reliable OEM battery manufacturer needs a complete quality management process.
Typical quality control includes:
Cell Inspection
Checking:
- 電圧の一貫性
- 内部抵抗
- Cell condition
Battery Assembly Inspection
含む:

- BMS connection testing
経年劣化試験
Battery packs are tested through charging and discharging cycles to verify performance.
最終検査
Before shipment, manufacturers check:
- Electrical performance
- 外観
- Protection functions
- Packaging requirements
Quality control helps maintain consistency during mass production.
9. Supporting Mass Production and Supply Management
After prototype approval, OEM manufacturers support customers with mass production.
Services may include:
- Production planning
- Material preparation
- Assembly process management
