5. Konfiguracja i instalacja
Proper installation is crucial for the safe and effective operation of your BMS. Always ensure the battery pack is disconnected from any power source before beginning installation.
5.1 Schemat okablowania powyżejview
Refer to the specific wiring diagram provided with your BMS model for precise connection points. Generally, the BMS connects to the battery pack via:
- B-: Main negative terminal of the battery pack.
- P-: Main negative terminal for load/charger.
- Przewody równoważące: Pojedyncza komórka objtage sensing wires connected from B1 to Bn (where n is the total number of series cells). Connect these in ascending order from the lowest cell voltage to the highest.
- Czujnik temperatury: Connect the NTC temperature sensor to the designated port on the BMS. Position the sensor to accurately measure battery temperature.
- Active Switch: Connect the active switch to enable/disable the BMS.
5.2 Heating Cable Installation (Optional)
If your BMS includes the heating function:
- Connect the green 5-PIN cable of the heating cable to the heating pad.
- Connect the black and red cables of the heating cable to the smart charger.
- Once the smart charger links with the BMS, the BMS will detect the battery temperature and automatically manage the heating function based on configured low-temperature charge protection settings.
