4. Konfiguracja i instalacja

Proper installation is critical for the performance and safety of your battery system. Follow these steps carefully:

4.1 Schemat okablowania powyżejview

The BMS features main terminals for battery negative (B-) and load/charger negative (P-), along with a series of balance wire connections (B1, B2, ... B24, B+). The heating function (if present) and communication ports (BT, RS485, CAN) are also integrated.

4.2 Procedura podłączenia

1. Podłącz zacisk B: Connect the main negative terminal of your battery pack to the B- terminal on the BMS. Use appropriate gauge wire for the expected current.
2. Podłącz przewody równoważące: Starting from the lowest cell (B1), connect each balance wire to its corresponding positive terminal on the battery cells. Ensure the order is correct (B1 to cell 1 positive, B2 to cell 2 positive, and so on) up to B+. Connect the B+ wire to the positive terminal of the entire battery pack. It is crucial to connect balance wires in the correct sequence to prevent damage.
3. Podłącz zacisk P: Connect the load/charger negative terminal to the P- terminal on the BMS. This is the common negative point for both charging and discharging.
4. Connect Temperature Sensors: If included, connect the temperature sensors to the designated ports on the BMS and place them strategically on the battery cells for accurate temperature monitoring.
5. Podłącz kable komunikacyjne: If using RS485 or CAN communication, connect the respective cables to the BMS and your external communication device (e.g., inverter, display).

Po wykonaniu wszystkich połączeń, przed podłączeniem zasilania należy jeszcze raz sprawdzić, czy każdy przewód jest prawidłowo ułożony i solidnie zamocowany.

5. Instrukcja obsługi

The JK Smart BMS is primarily managed and monitored via its dedicated mobile application, accessible via Bluetooth.
