5. Орнотуу жана орнотуу
Proper wiring is crucial for the correct function and safety of the BMS and battery pack. Follow these steps carefully.
- Step 1: Soldering Wires
Connect the first wire (black wire) to the total negative terminal of the battery (B-). Connect the second wire (red wire) to the first series battery positive terminal. Continue connecting subsequent red wires to each successive series battery positive terminal until all balance wires are connected. - Step 2: Test the Wires
After connecting the balance wires, measure the voltage between two adjacent wires from the header. Ensure that the voltage readings are consistent with individual cell voltages, confirming that the wires are not connected in the wrong order. - Step 3: Connect Output Wires and Activate
Connect the B- wire of the protection board to the total negative terminal of the battery. Then, plug the sampling row wires (balance wires) into the protection board. After activating the protection board, confirm that the voltage before the board (battery voltage B+ to B-) and the voltage after the board (P+ to P-) are the same.
5.1-сүрөт: Detailed wiring diagram for DALY BMS installation. This diagram illustrates the connections for the sampling line (balance wires), B- (main negative), and P- (load negative), showing how the BMS integrates with the battery pack and external loads/chargers.
Эскертүү: The NTC (Negative Temperature Coefficient) thermistor is integrated into G series models. Ensure it is positioned correctly to monitor battery temperature.
6. Иштөө нускамалары
Once properly installed, the DALY BMS operates automatically to manage and protect your battery pack.
- Заряддоо: Connect your compatible battery charger to the P+ and P- terminals (or designated charge terminals if separate). The BMS will monitor cell voltages and temperatures, initiating passive balancing as needed and terminating charging if overvoltage or overcurrent conditions are detected.
- Заряддоо: Connect your load to the P+ and P- terminals. The BMS will monitor discharge current, cell voltages, and temperature, disconnecting the load if overcurrent, undervoltage, or over-temperature conditions occur.
- Баланстоо: The BMS features passive equalization to help maintain cell voltage consistency during charging. This function activates when cells reach a certain voltage босого.
7. Техникалык тейлөө
- Бардык зымдарды туташтыргычтын бекемдигин жана коррозиясын дайыма текшерип туруңуз.
- Keep the BMS unit clean and free from dust and debris.
- While the unit is waterproof, avoid prolonged submersion or exposure to harsh chemicals.
- Monitor battery pack performance. Any significant deviation in capacity or voltagи иликтөө керек.
8. Кыйынчылыктарды
If you encounter issues with your DALY BMS, consider the following:
- BMS not activating / No output voltage:
- Check all wiring connections, especially the balance wires and main power connections (B- and P-).
- Ensure the battery pack voltage is within the operational range.
- Verify that the balance wires are connected in the correct sequence and that no wires are swapped.
- If the BMS has a separate activation switch or procedure, ensure it has been followed.
- Battery not charging / Discharging:
- Ашыкча көлөмүн текшериңизtage же undervoltage protection activation. Measure individual cell voltages.
- Verify charger and load connections.
- Check for overcurrent protection activation. Reduce load or charging current.
- Inspect the NTC temperature sensor for proper placement and connection.
- Unbalanced cells:
- Ensure the BMS has sufficient time to balance cells during charging. Passive balancing is a slow process.
- Verify that the balance wires are correctly connected to each cell.
- If cell imbalance persists, individual cell testing may be required.
