锂电池制造商如何支持OEM的产品开发

Lithium batteries have become an important power source for electric vehicles, industrial equipment, robotics, medical devices, marine applications, and energy storage systems.

For many equipment manufacturers, developing a suitable battery pack requires more than selecting battery cells. A complete battery solution involves electrical design, battery management system (BMS) development, mechanical integration, safety testing, and production management.

Working with an experienced lithium battery OEM manufacturer allows companies to develop battery packs that match their equipment requirements and product specifications.

This article explains how lithium battery manufacturers support OEM product development from initial requirements to mass production.

1. Understanding Customer Application Requirements

The first step in OEM battery development is understanding the customer’s product requirements.

• 单元配置
• BMS selection
• 结构设计
• Connector selection
• 热管理设计

The battery design process needs to balance:

• 电压
• 容量
• Current output
• 尺寸
• 重量
• 安全要求

For example, a 48V battery pack may require different cell configurations depending on capacity and discharge requirements.

3. Battery Cell Selection and Matching

Battery cells are the core components of a lithium battery pack.

OEM manufacturers help customers select suitable cells based on application requirements.

Common battery cell options include:

Cylindrical Lithium Cells

例如

• 18650 cells
• 21700 个细胞

优势

Cell selection depends on:

• 能源需求
• 放电速率
• 运行环境
• Product lifetime requirements

4. Custom BMS Development and Integration

The Battery Management System (BMS) is an important part of a customized lithium battery pack.

OEM battery manufacturers help design BMS functions according to equipment requirements.

BMS的常见功能包括：

• 过充电保护
• 过放电保护
• 过流保护
• 短路保护
• 温度监测
• Cell voltage balancing

For smart equipment, battery packs may require communication functions:

• CAN总线
• 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.

性能测试

测试可能包括：

• Charging test
• Discharging test
• Capacity test
• 温度测试
• Protection function test

Product Verification

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

• 安装兼容性
• Operating performance
• 通信功能

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:

• 电池外壳设计
• 安装结构
• 防水设计
• 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.

常见的认证包括

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:

• 电压一致性
• 内部电阻
• Cell condition

Battery Assembly Inspection

包括

• 焊接质量
• Wiring inspection
• BMS connection testing

老化测试

Battery packs are tested through charging and discharging cycles to verify performance.

最终检查

Before shipment, manufacturers check:

• Electrical performance
• 外观
• 保护功能
• 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
• Quality inspection
• Delivery coordination

For companies launching new products, stable production support helps maintain supply continuity.

10. Advantages of Working With a Lithium Battery OEM Manufacturer

Partnering with an OEM battery manufacturer can help companies:
