5. Configuration et installation
Proper installation is crucial for the safe and efficient operation of your BMS. Follow these steps carefully:
5.1 Vérifications avant l'installation
- Ensure your battery pack matches the BMS specifications (4S-8S, Li-ion/LiFePO4/LTO).
- Verify all battery cells are balanced and within a healthy voltage range before connecting the BMS.
- Rassemblez tous les outils et composants nécessaires.
5.2 Connexions de câblage
Important: Connect the balance wires first, then the main power cables. Disconnect in reverse order.
- Connexion du fil d'équilibrage : Connectez le sampling cable to each cell's positive terminal, starting from B- (0V) up to B+ (total voltage). Ensure the sequence is correct.
- B- Connection: Connect the main negative terminal of the battery pack to the B- port on the BMS.
- P- Connection: Connect the negative terminal of your load/charger to the P- port on the BMS.
- Connexion B+ : Connect the main positive terminal of the battery pack to the B+ port on the BMS.
- Ports de communication : Connect RS485, CAN, or UART cables as required for external communication or monitoring.
- Capteur NTC : Attach the NTC temperature sensor to a central cell or area within the battery pack to monitor temperature.
