1. บทนำ

This manual provides essential information for the proper installation, operation, and maintenance of your LiebeWH 5S Li-ion Battery Protection Board. This board is designed to manage and protect 5 series Li-ion battery cells, commonly used in electric power tools and other applications requiring 18.5V (nominal) to 21V (full charge) battery packs with a maximum discharge current of 15A. It integrates critical protection features to ensure battery longevity and safe operation.

2. ข้อมูลด้านความปลอดภัย

• Always handle Li-ion batteries with extreme care. Incorrect handling can lead to fire, explosion, or severe injury.
• Ensure all connections are correct before applying power. Reverse polarity can damage the protection board and batteries.
• Do not exceed the specified maximum discharge current of 15A.
• Use appropriate wiring gauges for the current draw to prevent overheating.
• ควรเก็บแผงวงจรให้ห่างจากความชื้น ฝุ่น และอุณหภูมิที่สูงหรือต่ำเกินไป
• Installation should be performed by individuals familiar with electronics and battery systems.
• Do not attempt to modify or repair the protection board.

3. สินค้าหมดview

The LiebeWH 5S Li-ion Battery Protection Board is a Battery Management System (BMS) designed for 5-series lithium-ion battery packs. It provides essential protection functions to safeguard your battery cells.

Figure 1: The protection board supports overcharge, over-discharge, and short circuit protection.

คุณสมบัติหลัก:

• การป้องกันการชาร์จไฟเกิน: Prevents individual battery cells from being charged beyond their safe voltagอี จำกัด
• การป้องกันการคายประจุเกิน: หยุดการคายประจุเมื่อเซลล์มีปริมาตรถึงระดับปลอดภัยขั้นต่ำtagเช่น การป้องกันความเสียหาย
• การป้องกันไฟฟ้าลัดวงจร: Automatically cuts off power in case of a short circuit to prevent damage and fire.
• ประสิทธิภาพที่มั่นคง: Provides reliable protection for 5S battery configurations.
• Integrated Charging/Discharging: The charging and discharging connectors are shared, simplifying wiring.

5. การตั้งค่าและการติดตั้ง

Careful wiring is crucial for the correct function and safety of the battery pack. Refer to the diagram below for connection points.

Figure 4: Connection points on the LiebeWH 5S Li-ion Battery Protection Board.

1. เตรียมแบตเตอรี่: Ensure your 5 Li-ion cells are balanced in voltage before connecting them to the BMS.
2. ระบุจุดเชื่อมต่อ: The board has specific pads for battery connections (B-, B1, B2, B3, B4, B+) and main power connections (P-, P+).
   • ข-: Connect to the negative terminal of the first battery cell (Cell 1 negative).
   • บี1: Connect to the positive terminal of Cell 1 and the negative terminal of Cell 2.
   • บี2: Connect to the positive terminal of Cell 2 and the negative terminal of Cell 3.
   • บี3: Connect to the positive terminal of Cell 3 and the negative terminal of Cell 4.
   • บี4: Connect to the positive terminal of Cell 4 and the negative terminal of Cell 5.
   • บี+: Connect to the positive terminal of the fifth battery cell (Cell 5 positive). This is the main positive terminal for the battery pack.
   • NS-: This is the main negative output/input terminal for the load/charger.
   • พี+: This is the main positive output/input terminal for the load/charger. This should be connected to B+.
3. ลำดับการเดินสายไฟ: Connect the balance wires (B-, B1, B2, B3, B4, B+) in sequence from the lowest voltage point to the highest. Then connect the main discharge/charge wires (P- and P+).
4. ตรวจสอบการเชื่อมต่อ: Double-check all connections for correct polarity and secure soldering. Incorrect wiring can lead to immediate damage.
5. ป้องกัน: After installation, ensure all exposed connections are properly insulated to prevent short circuits.

6. คู่มือการใช้งาน

Once properly installed, the LiebeWH 5S Li-ion Battery Protection Board operates automatically to manage your battery pack. It continuously monitors the voltage of each cell and the overall current flow.

• การชาร์จ: Connect your 21V Li-ion charger to the P+ and P- terminals. The board will manage the charging process, preventing overcharge of individual cells.
• การปลดประจำการ: Connect your electric power tool or other load to the P+ and P- terminals. The board will allow discharge up to 15A and will cut off power if any cell reaches its over-discharge threshold.
• การเปิดใช้งานการป้องกัน: If an overcharge, over-discharge, or short circuit event occurs, the board will temporarily cut off power to protect the battery. Normal operation should resume once the fault condition is removed. For over-discharge, a charger connection may be required to reset the protection.

7. การบำรุงรักษา

The LiebeWH 5S Li-ion Battery Protection Board is designed for low maintenance. However, following these guidelines can help ensure its longevity:

• รักษาความสะอาด: Periodically inspect the board for dust or debris and gently clean with a soft, dry brush if necessary.
• หลีกเลี่ยงความชื้น: Ensure the board remains dry. Moisture can cause corrosion and short circuits.
• การควบคุมอุณหภูมิ: Operate the battery pack and BMS within recommended temperature ranges. Extreme heat or cold can affect performance and lifespan.
• ตรวจสอบการเชื่อมต่อ: Occasionally check that all soldered connections remain secure and free from corrosion.
