4. Configurazione e installazione

Follow these steps for proper installation of your DALY Smart BMS. Refer to the wiring diagram for visual guidance.

1. Preparare il pacco batteria: Ensure your 24-series LiFePo4 battery pack is assembled and individual cell voltagsono bilanciati.
2. Collegare i cavi di bilanciamento:
   • Passaggio cruciale: Before connecting the balance wires to the BMS, ensure the white connector end is disconnected from the BMS.
   • Carefully weld or connect the individual balance wires (sampling cable) to each cell of your battery pack, starting from the negative terminal (B0) and progressing to the positive terminal (B24).
   • Ensure the DALY matching balance wires are used (regular length 450 mm / 17.72 inch) and that the red cooling surface of the BMS remains uncovered for proper heat dissipation.
3. Collegare i cavi di alimentazione principali:
   • Connect the main negative wire from the battery pack to the 'B-' terminal on the BMS.
   • Connect the main negative output wire for the load/charger to the 'P-' terminal on the BMS.
   • The main positive wire from the battery pack (B+) connects directly to the load/charger, bypassing the BMS.
4. Connect Balance Wire Connector: Once all balance wires are securely connected to the battery cells and the main power wires are in place, carefully plug the white connector of the balance wires into the designated port on the BMS.
5. Attiva BMS: Press the activation button on the BMS board to power it on for the first time.
6. Collegare i moduli di comunicazione:
   • For Bluetooth communication, plug the Bluetooth module into the dedicated port on the BMS.
   • For UART communication with a PC, connect the UART cable to the BMS and your computer.
   • If applicable, connect RS485 or CAN communication modules.
7. Sensore NTC: Connect the NTC temperature sensor to the BMS and place it appropriately on the battery pack for accurate temperature monitoring.

5. Istruzioni per l'uso

The DALY Smart BMS allows for advanced monitoring and configuration through its communication interfaces.

5.1 Funzionamento dell'app Bluetooth

1. Scarica l'app: Cercare the DALY BMS app on your smartphone's app store.
2. Connessione tramite Bluetooth: Ensure the Bluetooth module is connected to the BMS and Bluetooth is enabled on your smartphone. Open the app and search for the BMS device.
3. Accesso iniziale: The initial password for the app is 123456.
4. Parametri di configurazione:
   • The default parameters in the app may not perfectly match your specific battery pack. It is crucial to verify and adjust these parameters, especially the total battery capacity (AH) and the number of series cells (24S for this model), to ensure accurate readings and optimal protection.
   • Incorrect capacity settings will result in inaccurate state of charge (SOC) percentages.
5. Monitorare lo stato della batteria: The app provides real-time data on cell voltages, volume totaletage, corrente, temperatura e stato di protezione.

5.2 PC Software Operation (via UART)

For detailed parameter configuration and data logging, connect the BMS to a computer using the UART cable and DALY PC software. Refer to the DALY website for software download and specific PC software tutorial videos.

6. Manutenzione

Regular maintenance ensures the longevity and reliable operation of your DALY Smart BMS.

• Ispezione visiva: Controllare periodicamente tutti i collegamenti elettrici per verificarne la tenuta e l'eventuale presenza di segni di corrosione o danni.
• Pulizia: Keep the BMS unit clean and free from dust and debris. Ensure the cooling surface is unobstructed.
• Aggiornamenti software: Check the DALY official website for any available firmware or software updates for the BMS or its accompanying applications.
• Parametro Review: Occasionalmente riview the configured parameters via the app or PC software to ensure they still align with your battery pack's condition and usage requirements.

7. Risoluzione Dei Problemi

If you encounter issues with your DALY Smart BMS, consider the following common troubleshooting steps:

• Nessuna alimentazione/Nessuna indicazione:
  • Verify all main power connections (B- and P-).
  • Ensure the activation button on the BMS has been pressed.
  • Controlla il volumetage del pacco batteria.
• Problemi di connessione Bluetooth:
  • Ensure the Bluetooth module is correctly plugged into the BMS.
  • Confirm Bluetooth is enabled on your smartphone and the app has necessary permissions.
  • Prova a riavviare l'app o il telefono.
  • Ensure no other devices are actively connected to the BMS via Bluetooth.
• Inaccurate State of Charge (SOC) or Voltage Letture:
  • Verify that the balance wires are correctly connected to each cell in sequence.
  • Check the battery capacity (AH) setting in the app/PC software; it must match your battery pack's actual capacity.
  • Ensure the number of series cells (24S) is correctly configured in the software.
• BMS Not Allowing Charge/Discharge:
  • Check for active protection alarms (e.g., overcharge, overdischarge, overcurrent, temperature) in the app.
  • Review the configured protection parameters in the app/PC software to ensure they are appropriate for your battery.
• Guasto del componente: In rare cases, a component failure on the BMS board may occur. If troubleshooting steps do not resolve the issue, contact DALY customer support for assistance.
