6. Configurazione e installazione

Un'installazione accurata è fondamentale per il corretto funzionamento e la sicurezza del tuo BMS. Segui attentamente questi passaggi:

6.1 Strumenti necessari

• Soldering iron (suggested temperature: 662 °F / 350 °C)
• Forbici
• Nastro biadesivo
• Tin wire
• Multimetro

6.2 Istruzioni per il cablaggio

1. Prepare Balance Wires: Before welding, ensure the white end of the balance wires and the BMS connection port are disconnected.
2. Weld Balance Wires: Carefully weld the black and red balance wires to your battery pack. Ensure each cell connection is accurate.
3. BMS Placement: Position the BMS ensuring its red cooling surface remains uncovered for optimal heat dissipation. Use DALY matching balance wires (regular length 450 mm / 17.72 inches).
4. Collegare i cavi di bilanciamento: After confirming all balance wires are correctly welded, connect the balance wire harness to the BMS connection port.
5. Collegare i cavi di alimentazione principali: Connect the main negative (B-) and positive (P-) cables from your battery pack to the corresponding terminals on the BMS.
6. Collegare gli accessori: Install the Bluetooth module, NTC temperature sensor, and UART cable to their respective ports on the BMS.

It shows the balance wire connections, the main negative (B-) and positive (P-) terminals, and the integration points for external devices like the Bluetooth module and UART cable.

6.3 BMS Activation

The BMS can be activated using one of two methods:

• Metodo 1: Press the activation button located on the battery board (if available).
• Metodo 2: Connect a charger to the battery pack to activate the BMS for its first use.

6.4 Initial Parameter Setup

The BMS comes with default protection parameters. However, it is essential to set the actual capacity (AH) of your battery pack. If the capacity is not set correctly, the displayed percentage of remaining power will be inaccurate. Other parameters can also be adjusted to meet your specific needs.

• The initial password for the smart board application to change parameters is 123456.
