4. Орнотуу жана орнотуу

Proper installation is crucial for the safe and efficient operation of your DALY BMS. This section provides general guidance. Always refer to the detailed wiring diagrams and safety precautions specific to your battery configuration.

4.1. Battery Cell Type and Series Connection

Ensure your battery pack consists of 4S (4 cells in series) LiFePO4 cells. The BMS is specifically designed for this configuration.

4.2. Current Rating Selection

The BMS current rating should match or exceed your controller's maximum operating current. For a 200A BMS, ensure your application's maximum continuous current draw does not exceed 200A.

4.3. Зымдарды туташтыруу

Connect the BMS to your battery pack according to the provided wiring diagram. Ensure all connections are secure and correctly polarized. The sampling cable must be connected to each cell's positive terminal in sequence, starting from B0 (negative terminal of the first cell) up to B4 (positive terminal of the fourth cell).

4.4. Active Balancer Connection

Connect the 5A active balancer module to the BMS and battery cells as per the instructions. The active balancer helps maintain voltage equilibrium across cells, which is vital for battery health and performance.

4.5. Parallel System Support

This DALY BMS supports multiple parallel systems, allowing you to increase overall battery capacity. When connecting multiple battery packs in parallel, ensure each pack has its own DALY BMS and that the parallel connections are made correctly to avoid current imbalances. The built-in current limiting module facilitates this expansion.

5. Иштөө нускамалары

5.1. Bluetooth/Wi-Fi Dongle Connection

The included 2-in-1 Bluetooth/Wi-Fi dongle enables smart monitoring of your battery system. Plug the dongle into the designated port on the BMS.

5.2. Mobile App Monitoring

Download the 'Smart BMS' mobile application from your device's app store. Follow the app's instructions to connect to your DALY BMS via Bluetooth or Wi-Fi. The app provides real-time data on battery voltage, current, temperature, state of charge (SOC), and individual cell voltages. You can also customize various parameters and receive system alerts.

6. Техникалык тейлөө

The DALY BMS is designed for minimal maintenance. However, regular checks can help ensure optimal performance:

• Визуалдык текшерүү: Periodically inspect all wiring and connections for any signs of wear, corrosion, or damage. Ensure all terminals are tight.
• Колдонмо мониторинги: Regularly check the Smart BMS app for any alerts or unusual readings. This can help identify potential issues early.
• Тазалык: Keep the BMS unit clean and free from dust and debris to ensure proper heat dissipation.
• Температура: Ensure the BMS operates within its specified temperature range. Avoid exposing it to extreme heat or cold.

7. Кыйынчылыктарды

This section addresses common questions and potential issues. For complex problems, contact DALY technical support.

7.1. General Questions and Solutions

• Q: What kind of battery cell type and how many cells are connected in series (Strings)?
  A: This BMS is designed for 4S LiFePO4 battery packs. Ensure your battery configuration matches this requirement.
• С: Канча amperes do I need?
  A: The BMS current rating (200A for this model) should be equal to or greater than your application's maximum continuous current draw. Using an undersized BMS can damage the battery and the BMS itself.
