5. การตั้งค่าและการติดตั้ง
Careful wiring is essential for the correct and safe operation of the BMS and parallel module. Follow these steps precisely:
- เตรียมชุดแบตเตอรี่: Ensure your lithium battery pack consists of 16 series cells (16S) with a nominal voltage of 60V. The DALY BMS + DALY parallel module must match the battery pack's type and string count exactly.
- Connect BMS to Battery: First, connect the main B- (negative) terminal of the BMS to the total negative terminal of your battery pack. Then, connect the balance wires from the BMS to each individual battery cell, starting from the lowest voltage cell (B0) up to the highest (B16). Ensure all balance lines are correctly wired to each battery cell before proceeding.
- Connect Parallel Module to BMS: The 1A parallel module has one wire outlet with 5 wires in total. Combine these 5 wires and connect them to the corresponding DO port of the BMS. Do not connect the parallel module to the BMS before all balance lines wire each battery cell.
- เชื่อมต่ออุปกรณ์ชาร์จ/เครื่องชาร์จ: Connect your load and charger to the P- (negative) and B+ (positive) terminals of the BMS as per the wiring diagram.
Figure 5.1: Detailed wiring diagram for the 1A parallel module with the DALY Smart BMS. It shows connections for the battery pack (B- to B+), the parallel module to the BMS's sampling cable port, and the main power connections (P- and B-).
The DALY parallel module is specifically designed for parallel lithium packs. It limits mutual high charging current caused by internal resistance and voltage differences between parallel lithium batteries during charging. This combination allows for safe and easy achievement of higher voltage for electrical devices.

6. คู่มือการใช้งาน
The DALY Smart BMS offers intelligent monitoring and control via its communication functions.
6.1 การสื่อสารบลูทู ธ
The BMS is equipped with a Bluetooth module, allowing you to monitor battery parameters and adjust settings using the DALY BMS app on your smartphone or tablet.
- ดาวน์โหลดแอพ: Download the official DALY BMS app from your device's app store.
- เชื่อมต่อบลูทู ธ : Ensure the Bluetooth module is connected to the BMS. Open the app and search for available BMS devices. Select your BMS to connect.
- พารามิเตอร์มอนิเตอร์: เมื่อเชื่อมต่อแล้ว คุณสามารถ view real-time battery parameters such as total voltage แต่ละเซลล์ฉบับtages, charge/discharge current, temperature, and State of Charge (SOC).
- ปรับการตั้งค่า: The app allows for specific parameter adjustments in designated areas. Refer to the app's internal help or the DALY website for detailed guidance on advanced settings.

6.2 Parallel Module Operation
The parallel module is triggered under specific conditions to manage current flow between parallel battery packs:
- When the overcharge current reaches warning level 2.
- When a built-in or preset valve value is reached.
The parallel module's release state is for discharge. It helps prevent high charging currents between parallel packs due to voltagอีความแตกต่าง

8 การแก้ไขปัญหา
This section addresses common issues you might encounter. For more complex problems, contact DALY support.
| ปัญหา | สาเหตุที่เป็นไปได้ | สารละลาย |
|---|---|---|
| BMS not powering on / no output | Incorrect wiring, loose connections, or battery voltagอีต่ำเกินไป | Verify all wiring according to the diagram. Check battery voltage. Ensure the main power switch (if present) is on. |
| ปัญหาการเชื่อมต่อบลูทูธ | Bluetooth module not connected, out of range, or app issues. | Ensure the Bluetooth module is securely connected to the BMS. Move closer to the BMS. Restart the app and try reconnecting. |
| Parallel module not functioning as expected | Incorrect connection, incompatible BMS, or parameters not met. | Confirm the parallel module is correctly connected to the BMS's DO port. Ensure the BMS and parallel module are of compatible types and string counts. Check app settings for parallel module parameters. |
| BMS trips or cuts off at lower than expected current (e.g., 42A for a 60A unit) | Overcurrent protection threshold set too low, or unit is a lower amperage variant. | ตรวจสอบเฉพาะ amperage rating of your BMS model. Check the overcurrent protection settings in the DALY BMS app and adjust if necessary, ensuring it aligns with your battery pack's capabilities. |
