4. セットアップと接続
Follow these steps to properly connect your Dyness LiFePO4 charger to your battery and power source:
- バッテリーを準備します: Ensure your LiFePO4 battery is in a stable, well-ventilated area. Verify that the battery terminals are clean and free of corrosion.
- DC出力ケーブルを接続します: Connect the DC output cable from the charger to your LiFePO4 battery. The charger features an Anderson 50A connector for easy and secure connection, along with M8 terminals for direct bolt-on applications. Ensure correct polarity: red to positive (+), black to negative (-).
- AC電源ケーブルを接続します。 Once the DC cable is securely connected to the battery, plug the AC power cable into the charger's AC input port.
- 壁のコンセントに接続します: Finally, plug the AC power cable into a standard wall outlet (100-240V AC, 50/60Hz).
- 接続を確認します: The LED indicators on the charger will provide real-time status updates (charging/full/error). Refer to the "Operating Instructions" section for details on LED indications.

5. 操作手順
Intelligent 3-Level Charging Mode
The Dyness LiFePO4 charger utilizes an intelligent 3-level charging algorithm to optimize battery performance and longevity:
- Pre-charge (T1): このイニシャルstage gently charges deeply discharged batteries, helping to restore them safely and extend their overall lifespan.
- Fast Charge (T2): この期間中tage, the charger delivers a constant current to rapidly charge the battery to approximately 80-90% of its capacity.
- コンスタントボリュームtage (T3): 最後のtage、充電器は一定の電圧を維持するtage while gradually reducing the current until the battery is fully charged. This ensures a safe and complete charge.
図5: A graph illustrating the 3-stage charging process (Pre-charge, Fast Charge, Constant Voltage) with corresponding voltage and current curves over time.
0V活性化関数
The charger features a 0V activation function, allowing it to reactivate deeply discharged LiFePO4 batteries, even if their Battery Management System (BMS) has triggered protection. This function safely brings the battery back to a normal voltage level, making it usable again.
図6: Depiction of the secure battery activation process, showing the charger's ability to reactivate LiFePO4 batteries after BMS protection has been triggered.
充電時間の目安
The charging time will vary depending on the battery capacity and its current state of charge. Approximate charging times for common LiFePO4 battery capacities are:
- 100Ah LiFePO4 battery: Approximately 5 hours
- 200Ah LiFePO4 battery: Approximately 10 hours
- 300Ah LiFePO4 battery: Approximately 15 hours
Note: These times are estimates and may vary based on battery condition, ambient temperature, and other factors.

6. メンテナンス
To ensure the longevity and optimal performance of your Dyness LiFePO4 charger, follow these simple maintenance guidelines:
- クリーニング： Disconnect the charger from both AC power and the battery before cleaning. Use a soft, dry cloth to wipe the exterior. Do not use liquid cleaners or solvents.
- ストレージ： 使用していないときは、充電器を直射日光や極端な温度を避け、涼しく乾燥した場所に保管してください。
- 換気： Regularly check that the ventilation openings are not blocked by dust or debris. The robust aluminum casing with an internal fan ensures optimal heat dissipation, but clear airflow is essential.
- ケーブル検査: Periodically inspect the AC and DC cables for any signs of damage, fraying, or loose connections. Replace damaged cables immediately.
