• Cell voltage balancing

For smart equipment, battery packs may require communication functions:

• CAN 버스
• RS485
• UART
• Modbus

For example, AGV and AMR manufacturers often require battery data communication with the equipment control system.

5. Prototype Development and Testing

Before mass production, OEM battery manufacturers usually provide prototype development services.

The prototype stage includes:

Battery Sample Production

Manufacturers assemble initial samples according to design specifications.

성능 테스트

Testing may include:

• Charging test
• Discharging test
• Capacity test
• 온도 시험
• Protection function test

Product Verification

The battery pack is tested with the customer’s equipment to confirm:

• Installation compatibility
• Operating performance
• 통신 기능

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:

• 배터리 케이스 설계
• 장착 구조
• 방수 설계
• 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.

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:

• 전압 일관성
• 내부 저항
• Cell condition

Battery Assembly Inspection

포함:

• 용접 품질
