5. Орнотуу жана орнотуу
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.
- Батареяларды даярдоо: Ensure your 5 Li-ion cells are balanced in voltage before connecting them to the BMS.
- Туташуу чекиттерин аныктоо: The board has specific pads for battery connections (B-, B1, B2, B3, B4, B+) and main power connections (P-, P+).
- B-: Connect to the negative terminal of the first battery cell (Cell 1 negative).
- B1: Connect to the positive terminal of Cell 1 and the negative terminal of Cell 2.
- B2: Connect to the positive terminal of Cell 2 and the negative terminal of Cell 3.
- B3: Connect to the positive terminal of Cell 3 and the negative terminal of Cell 4.
- B4: Connect to the positive terminal of Cell 4 and the negative terminal of Cell 5.
- B+: Connect to the positive terminal of the fifth battery cell (Cell 5 positive). This is the main positive terminal for the battery pack.
- P-: This is the main negative output/input terminal for the load/charger.
- P+: This is the main positive output/input terminal for the load/charger. This should be connected to B+.
- Зымдарды тартуу ырааттуулугу: 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+).
- Байланыштарды текшерүү: Double-check all connections for correct polarity and secure soldering. Incorrect wiring can lead to immediate damage.
- Insulate: After installation, ensure all exposed connections are properly insulated to prevent short circuits.
6. Иштөө нускамалары
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.
- Заряддоо: Connect your 21V Li-ion charger to the P+ and P- terminals. The board will manage the charging process, preventing overcharge of individual cells.
- Заряддоо: 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.
- Коргоону активдештирүү: 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. Техникалык тейлөө
The LiebeWH 5S Li-ion Battery Protection Board is designed for low maintenance. However, following these guidelines can help ensure its longevity:
