4. الإعداد والتثبيت
Proper installation is crucial for the safe and efficient operation of the BMS. Follow these steps carefully.
4.1. Battery Pack Wiring
When assembling your battery pack, ensure you correctly identify the total positive and total negative terminals. Pay close attention to the B- and P- terminals on the BMS.
- Connect the black B- wire to the total negative terminal of the battery pack.
- Connect the red B+ wire to the total positive terminal of the battery pack.
- ربط sampling wires in sequence, starting from the negative terminal (B0) and progressing to the positive terminals of each cell string (B1, B2, etc.).
- مهم: When soldering the wires, ensure they are soldered in the correct order before plugging them into the BMS. Misfiring protection is limited to 6 strings; incorrect wiring for more than 6 strings can damage your BMS.
- If using a BMS compatible with more strings than your battery pack (e.g., an 8-17S BMS for an 8S pack), seal the remaining unused sampling cables with insulation tape.

4.2. التحقق من الأسلاك
Before connecting the sampling cable to the BMS, verify the voltage of each wire using a multimeter.
- Place the black probe of the multimeter on the B0 wire (total negative).
- Place the red probe on B1, then B2, and so on. The voltage readings should increase incrementally.
- If the multimeter displays positive voltage readings that increase step by step, the wiring is correct.
- حذر: During testing, do not let the two probes touch each other, as this may cause a cable short circuit.
4.3. التوصيلات النهائية
- Insert the NTC (temperature sensor) cable into the NTC port on the BMS.
- Connect the B- wire to the BMS B- terminal.
- Plug in the sampling cable connector to the corresponding port on the BMS.
- Connect the B+ wire to the BMS B+ terminal.
- If the BMS's green light is on, the BMS is working properly.
5. تعليمات التشغيل
The DALY Smart Active Balance BMS offers multiple ways to monitor and configure its parameters.
5.1. Mobile Application (APP)
Download the "BalanceBMS" app from your iOS or Android app store. The app allows you to monitor cell voltages, temperatures, and other parameters in real-time. It also supports cloud monitoring and data logging capabilities.
5.2. PC Host Software
For advanced monitoring and configuration, connect the BMS to a PC using the provided UART cable or RS485/CAN port cable. You will need to download the corresponding drivers and PC host software from the DALY webموقع.
- Download the PC Host software and necessary drivers (CAN or RS485) from the official DALY webموقع.
- Connect the UART cable to the BMS and your PC.
- Open the PC Host software. Select the correct communication mode (UART, RS485, or CAN) and port settings.
- يسمح لك البرنامج بـ view real-time battery data, including total voltage, current, temperature, SOC, cell voltages, and MOS temperature.
- You can also modify various parameters such as balance current, sleep time, rated capacity, and protection parameters.
- The software supports switching between Chinese and English languages.
5.3. LCD Screen (Optional Accessory)
An optional LCD screen can be connected to the UART or RS485 port to display real-time battery information and allow parameter changes via a 4.3-inch touch screen.
5.4. Key Switch (Optional Accessory)
The optional key switch can be used to switch the discharge MOSFET on and off. Other functions may also be customized.
5.5. Heating Module (Optional Accessory)
A heating module can be used in cold environments to start the BMS, ensuring optimal performance in low temperatures.
6. الصيانة
To ensure the longevity and optimal performance of your DALY Smart Active Balance BMS, consider the following maintenance tips:
- قم بفحص جميع توصيلات الأسلاك بشكل منتظم للتأكد من عدم وجود أي تآكل أو إحكام.
- حافظ على نظام إدارة المباني نظيفًا وخاليًا من الغبار والحطام.
- Avoid exposing the BMS to extreme temperatures or moisture beyond its operating specifications.
- Monitor battery cell balance and overall battery health using the mobile app or PC software.
- Ensure proper ventilation around the BMS, especially for high-current applications.
7. استكشاف الأخطاء وإصلاحها
If you encounter issues with your DALY Smart Active Balance BMS, refer to the following common troubleshooting steps:
| مشكلة | السبب المحتمل | حل |
|---|---|---|
| BMS not powering on (no green light) | Incorrect B- or B+ wiring; faulty battery connection. | Verify B- and B+ connections to the battery pack. Ensure the battery pack has sufficient voltage. |
| حجم غير صحيحtage readings in app/software | غير صحيح sampling wire connection order; loose sampling wires. | Re-check sampling wire connections and order. Ensure all wires are securely attached and soldered. |
| BMS not communicating with app/PC | Bluetooth/UART/RS485/CAN connection issue; incorrect drivers/software settings. | Ensure Bluetooth is enabled on your device. Check cable connections. Verify correct COM port and baud rate in PC software. Reinstall drivers if necessary. |
| Battery cells out of balance | Balancing function disabled; significant cell voltagوالفرق هو. | Ensure active balancing is enabled in the app/PC software. Allow sufficient time for balancing to occur. Check individual cell health. |
| BMS triggering protection frequently | Overcharge/overdischarge/overcurrent conditions; incorrect protection parameters. | Review battery usage and charging/discharging limits. Adjust protection parameters in the app/PC software if they are too conservative for your battery type and usage. |
