3. การตั้งค่าและการติดตั้ง
Proper installation is crucial for the safe and effective operation of your DALY BMS. Follow these steps carefully:
- เตรียมชุดแบตเตอรี่: Ensure your 24S LiFePO4 battery pack is assembled and all cells are balanced. Mark the battery pack's positive (B+) and negative (B-) terminals, as well as individual cell connection points (B1, B2, ..., B24).
- Determine Sampคะแนนลิง: The video below demonstrates how to accurately determine the sampling points on your battery pack. This involves identifying the total negative electrode (B-), and then sequentially marking the connection points between each cell (B1, B2, etc.) up to the total positive electrode (B+).
- ตรวจสอบ Sampling Points with Multimeter: Before connecting the balance wires, use a multimeter to verify the voltage ในแต่ละ sampling point. Set the multimeter to DC voltage mode. Place the black meter pen at the B- (total negative) point. Then, place the red meter pen at B1, B2, and so on. The voltage should increase incrementally (approximately 3V per cell for LiFePO4) as you move up the string. If the voltage does not increase consistently, your sampling points or battery connections may be incorrect.
- เชื่อมต่อสายบาลานซ์: The BMS comes with a sampling cable. The black wire of this cable connects to the total negative electrode (B-). The subsequent red wires connect to B1, B2, and so on, in ascending order, up to B24. Ensure all balance wires are securely connected to their corresponding sampจุดหลิง
- Connect BMS to Battery Pack: After all balance wires are connected and verified, connect the main positive (P+) and negative (P-) terminals of the BMS to your battery pack's main output terminals.
- การตรวจสอบขั้นสุดท้าย: Double-check all connections for proper polarity and secure fit.

Video 1: DALY Smart BMS Wiring Tutorial (Sampling point determination)
This video provides a detailed visual guide on how to correctly identify sampling points and wire your DALY BMS to a battery pack. It demonstrates the use of a multimeter to verify connections and ensure proper voltage readings, which is critical for safe operation.
4. คู่มือการใช้งาน
The DALY 24S 72V 200A Standard BMS operates automatically to protect your LiFePO4 battery pack. As a standard BMS, it does not feature communication functions (e.g., Bluetooth, UART, RS485, CAN). Its primary function is to monitor and protect the battery cells from various electrical hazards.
Once properly installed and connected, the BMS will continuously monitor the battery pack's voltage, current, and temperature. It will automatically engage its protection mechanisms if any parameter exceeds safe operating limits (e.g., during overcharge, overdischarge, overcurrent, or short circuit events). The integrated cooling fan will activate as needed to manage the temperature of the BMS itself.
No direct user interaction is required for its protective functions. For systems requiring data monitoring or advanced control, a Smart BMS with communication capabilities would be necessary.
5. การบำรุงรักษา
To ensure the longevity and optimal performance of your DALY BMS and battery pack, consider the following maintenance guidelines:
- การตรวจสอบด้วยสายตาเป็นประจำ: Periodically inspect the BMS and all wiring connections for any signs of damage, corrosion, or loose connections.
- รักษาความสะอาดและแห้ง: Ensure the BMS is kept clean and free from dust, dirt, and moisture. While it is dustproof and waterproof, prolonged exposure to harsh conditions should be avoided.
- ตรวจสอบความร้อนสูงเกินไป: Although equipped with a cooling fan, ensure adequate airflow around the BMS, especially during high-current operation, to prevent excessive heat buildup.
- สุขภาพแบตเตอรี่: The BMS protects the battery, but the overall health of the battery cells is also important. Ensure your battery cells are of good quality and properly matched.
6 การแก้ไขปัญหา
If you experience issues with your battery pack or the BMS, consider these basic troubleshooting steps:
- ไม่มีเอาท์พุทVoltage: Check all wiring connections, especially the main positive and negative terminals, and the balance wires. Ensure they are secure and correctly connected. Verify the battery pack's total voltage directly at the battery terminals.
- ระบบ BMS ไม่ทำงาน: Confirm that the balance wires are correctly connected and that the voltage ในแต่ละ sampling point is within the expected range. An incorrect wiring sequence can prevent the BMS from functioning.
- Over-Protection Issues: If the BMS frequently triggers protection (e.g., cutting off power), check if the load current exceeds the BMS's rated continuous discharge current (200A). Also, verify that individual cell voltages are not consistently too high or too low, indicating an imbalance or faulty cell.
- ความร้อนสูงเกินไป: Ensure the cooling fan is operating. Check for any obstructions to airflow around the BMS. Reduce the load if continuous high current is causing excessive heat.
- เสียงหรือกลิ่นผิดปกติ: Immediately disconnect the battery pack from the load and charging source. This may indicate a serious fault within the BMS or battery.
