5. Instal·lació i cablejat

Proper installation is crucial for the safe and effective operation of your BMS. Follow these steps carefully. The wiring diagram below uses a K series 60A BMS as an example, but the principles apply to the 16S 48V 100A model.

1. Step 1: Solder the Sampling Cables. The first black cable in the sampling cable set connects to the overall negative terminal (B-) of the battery pack. Subsequent red cables connect to the positive terminal of each series cell, starting from the first string, then the second, and so on, until all cables are connected to their respective cell positive terminals.
2. Step 2: Check the Cables. After connecting the cables, use a multimeter to measure the voltage between two adjacent cells, starting from the header. Ensure there are no wrong connections or missing connections.
3. Step 3: Connect Output Wires. Connect the B- wire of the BMS to the total negative terminal of the battery pack. Then, plug the sampling cable into the BMS. After activating the BMS, verify that the battery voltage (between B+ & B-) and the voltage between P+ & P- are consistent.

Safety Warning: Incorrect wiring can damage the BMS, battery, and connected equipment. Always double-check all connections before applying power.

6. Funcionament

The DALY Smart BMS can be monitored and configured via a mobile application or PC software using the provided 2-in-1 Bluetooth/Wi-Fi dongle.

6.1. App Connection and Monitoring

• Connexió Bluetooth: Plug in the Bluetooth/Wi-Fi dongle to the appropriate UART port on the BMS. Ensure Bluetooth is enabled on your mobile device. Open the DALY Smart BMS app (available for iOS and Android). The app should automatically detect and connect to the BMS (Bluetooth activation-free function).
• Connexió Wi-Fi: For remote monitoring, connect the Wi-Fi dongle to a Wi-Fi router. Configure the Wi-Fi settings within the app to establish a long-distance connection. This allows you to monitor battery status and adjust parameters from anywhere with internet access.
• Paràmetres de seguiment: The app displays real-time data such as State of Charge (SOC), total voltage, vol cel·lular individualtages, current, temperature, and cycle count. It also provides alarms for protection events.
• Ajust de paràmetres: The app allows you to customize various protection parameters, such as overcharge/overdischarge voltage limits, overcurrent thresholds, and balancing settings.

6.2. CAN/485 Communication

The BMS supports CAN and RS485 communication protocols, allowing integration with other systems or devices. Use the provided CAN/485 5-pin cable to connect to compatible equipment. Refer to the specific documentation of your external system for detailed communication setup.
