72V電動バイク用バッテリーのサプライヤー選定：OEMバイヤー向け完全ガイド

The 72V electric motorcycle battery system is commonly used in applications that require higher power output, longer riding range, and stable performance. Compared with lower-voltage systems, a 72V battery pack is often selected for high-power electric motorcycles, delivery vehicles, performance scooters, and commercial mobility applications.

However, choosing a suitable 72V electric motorcycle battery supplier is not only about finding a battery with the correct voltage. The battery pack needs to match the vehicle system, including the motor, controller, charger, installation space, and operating environment.

For electric motorcycle manufacturers and distributors, the battery supplier should have capabilities in:

• バッテリーパックの設計
• 細胞の選択
• BMS開発
• 構造のカスタマイズ
• 安全性試験
• Mass production management

A reliable supplier can help reduce integration problems and improve product consistency during long-term production.

Dongguan Yizhan Electronics Technology Co., Ltd. provides customized lithium battery PACK solutions for electric motorcycles, e-bikes, industrial vehicles, and other electric mobility applications.

What Is a 72V Electric Motorcycle Battery?

A 72V electric motorcycle battery pack is a lithium battery system designed to provide approximately 72 volts nominal output.

A typical lithium-ion 72V configuration usually uses:

• 20 series (20S) battery cells
• Fully charged voltage: around 84V
• Different parallel configurations depending on capacity requirements

The final battery specifications depend on:

• モーター出力
• コントローラの電流
• Required riding range
• 車両重量
• アプリケーション環境

例えば、こうだ：

A 72V system should be designed as a complete power solution rather than simply selecting a higher voltage battery.

Why Choose a Professional 72V Electric Motorcycle Battery Supplier?

1. Battery Design Needs to Match Vehicle Requirements

A professional battery manufacturer evaluates the complete vehicle system before designing the battery pack.

重要なパラメータには、次のようなものがあります：

Motor Power

Higher-power motors require batteries with suitable discharge capability.

例えば、こうだ：

• 1000W motor
• 2000W motor
• 3000W+ motor

may require different battery current outputs.

Controller Compatibility

The battery must match:

• 連続放電電流
• ピーク放電電流
• Controller protection settings

An incorrectly designed battery may cause:

• 電圧降下
• 加速度の低下
• BMS保護機能の作動

Installation Space

Electric motorcycles have limited battery compartments.

Battery suppliers need to consider:

• バッテリー寸法
• 取り付けブラケット
• Cable position
• コネクタの選定
• 防水構造

How to Select the Right Battery Cells for a 72V Motorcycle Battery?

Battery cells directly influence:

• エネルギー密度

• ブルートゥース・モニタリング

Smart BMS allows vehicle manufacturers to monitor:

• Battery status
• 残りの容量
• 障害情報
• 動作条件

Check the Manufacturing Process of the Battery Supplier

A professional 72V battery manufacturer should have a controlled production process.

Battery Cell Inspection

Before assembly:

• 電圧試験
• 内部抵抗試験
• Capacity checking
• セルの照合

are important steps.

Consistent cells help improve battery pack performance.

PACK Assembly Process

Typical production steps include:

1. 細胞の配列
2. Welding connection
3. BMS設置
4. Wiring assembly
5. Housing installation
6. 性能テスト

For electric motorcycle applications, the battery pack also needs mechanical protection against:

• 振動
• 衝撃
• ダスト
• 水分

Aging and Final Testing

Before shipment, battery packs should complete testing procedures such as:

• Charging test
• Discharging test
• Protection test
• 通信テスト
• エージングテスト

These processes help verify product consistency.

Certifications and Compliance for 72V Electric Motorcycle Batteries

When exporting electric motorcycle batteries, manufacturers should consider market requirements.
