3. Орнотуу жана орнотуу

Proper installation is crucial for the safe and effective operation of your DALY BMS. Follow these steps carefully:

1. Батарея топтомун даярдоо: 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).
2. Determine Sampling упайлар: 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+).
3. Текшерүү Сampling Points with Multimeter: Before connecting the balance wires, use a multimeter to verify the voltagар бир сampling 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.
4. Connect Balance Wires: 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 sampлиния пункттары.
5. 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.
6. Акыркы текшерүү: 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. Иштөө нускамалары

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. Техникалык тейлөө

To ensure the longevity and optimal performance of your DALY BMS and battery pack, consider the following maintenance guidelines:

• Үзгүлтүксүз визуалдык текшерүү: Periodically inspect the BMS and all wiring connections for any signs of damage, corrosion, or loose connections.
• Таза жана кургак кармаңыз: 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.
• Ашыкча ысып кетүү үчүн текшерүү: Although equipped with a cooling fan, ensure adequate airflow around the BMS, especially during high-current operation, to prevent excessive heat buildup.
• Батареянын ден соолугу: 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. Кыйынчылыктарды

If you experience issues with your battery pack or the BMS, consider these basic troubleshooting steps:

• No Output Voltage: 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.
• BMS Not Activating: Confirm that the balance wires are correctly connected and that the voltagар бир сampling 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.
• Ашыкча ысып кетүү: 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.
• адаттан тыш үндөр же жыттар: Immediately disconnect the battery pack from the load and charging source. This may indicate a serious fault within the BMS or battery.
