6.設置と配線
Proper wiring is critical for the safe and correct operation of the BMS. Refer to the wiring diagram and follow these steps carefully.
必要なツール:
- Soldering machine (recommended 662 °F/350°C)
- はさみ
- 両面テープ
- Tin wire
- マルチメーター
配線手順:
- バッテリーパックを準備します。 Ensure your Li-ion 3S 12V battery pack is assembled and cells are balanced.
- バランスワイヤを接続します。 Carefully connect the balance wires to each cell in the correct sequence, starting from the negative terminal (B-) of the first cell.
- Connect Main Power Wires: Connect the main negative (B-) and positive (P+) wires from the battery pack to the corresponding terminals on the BMS.
- 負荷/充電器を接続: Connect your load and charger to the common port (P-) of the BMS.
- Connect BMS Balance Port: 重要： Before connecting the balance wires to the BMS connection port, ensure the white end of the balance wires is disconnected from the BMS. Only after all black and red main wires are welded to the battery pack, connect the balance wires to the BMS port.
- Activate BMS: Plug in the NTC temperature sensor and Bluetooth module. Press the button on the Bluetooth module to activate the Smart BMS.
- 接続を確認します。 マルチメーターを使用して容量を測定するtage between adjacent balance cables. This voltage should be approximately the nominal voltage of a single cell string.
注記： Keep the BMS red cooling surface side uncovered to ensure proper heat dissipation. Use DALY matching balance wires (regular length 450 mm / 17.72 inch).

7. Operating Instructions (Bluetooth App & PC Software)
The DALY Smart BMS can be monitored and configured using a mobile application or PC software via Bluetooth or UART connection.
7.1 Mobile App Setup and Usage:
- アプリをダウンロードする： 検索する "Smart BMS" in the Huawei App Store or Apple App Store and download the application.
- BMS に接続します: Open the Smart BMS APP and connect to the corresponding Bluetooth device name (e.g., DL-XXXXXXXX).
- 初期設定: For the first power-on, the battery capacity must be set to the actual capacity of your battery pack. The initial password for parameter settings is 123456. Failure to set the correct capacity will result in inaccurate SOC readings.
- モニターパラメータ: The app displays real-time battery parameters such as total voltage、現在の個々のセルのボリュームtages, temperature, and SOC.
- 設定を調整します: Navigate to the "Parameter Settings" section to adjust protection thresholds for over-charge, over-discharge, over-current, and temperature.
- 自動校正: The BMS automatically calibrates when the battery is charged until the voltage reaches a high level 2 alarm.
