Wiring Instructions
- Даярдоо: Ensure all power sources are disconnected from the battery pack. Use appropriate safety gear. Soldering machine (suggested 662°F/350°C), scissors, double-sided tape, tin wire, and a multimeter are recommended tools.
- Balance Wires Connection: Connect the balance wires to the battery cells. It is critical to connect the balance wires to the battery pack мурун connecting the black wire (B-) and red wire (P-) to the BMS.
- BMS Connection: Connect the black wire (B-) from the battery pack to the B- terminal on the BMS. Connect the red wire (P-) from the battery pack to the P- terminal on the BMS.
- NTC and Bluetooth Module: Plug in the NTC (Negative Temperature Coefficient) sensor and the Bluetooth module into their respective ports on the BMS.
- Жандандыруу: Press the button on the Bluetooth module to activate the smart BMS.
- Алгачкы текшерүү: Use a multimeter to verify the internal resistance of the BMS. A reading of approximately 0Ω (multimeter deviation 0.1Ω) indicates proper conduction.

Programmable Protection Functions
The BMS offers several programmable protection features to safeguard your battery pack:
- Ашыкча заряддан коргоо: Stops charging when battery voltage reaches a set limit.
- Ашыкча разряддан коргоо: Stops discharging when battery voltage белгиленген чектен төмөн түшөт.
- Ашыкча ток коргоо: Stops charging or discharging if current exceeds programmed limits.
- Температураны коргоо: Stops all current if battery temperature reaches critical limits (low temperature charging protection at -1°C).
- Кыска туташуулардан коргоо: Кыска туташуулардан келип чыккан зыяндын алдын алат.
- Тtage Баланстоо: Actively balances cell voltagоптималдуу батареянын ден соолугу үчүн.
Initial Setup of Battery Capacity:
For the first power-on, the battery capacity must be set to the actual capacity of your battery pack. The initial password for parameter changes is 123456. Failure to set the correct capacity will result in inaccurate State of Charge (SOC) calculations.

Жалпы маселелер жана чечимдер
| Көйгөй | Мүмкүн себеп | Чечим |
|---|---|---|
| BMS not activating / No power | Incorrect wiring; Bluetooth module not plugged in or activated; Battery voltage өтө төмөн. | Verify all wiring connections according to the diagram. Ensure the Bluetooth module is securely plugged in and its button is pressed to activate the BMS. Check battery voltage. |
| Bluetooth байланышы көйгөйлөрү | Bluetooth module not activated; App not installed correctly; Interference; Out of range. | Ensure the Bluetooth module is activated. Reinstall the "Smart BMS" app. Move closer to the BMS. Check for other Bluetooth devices causing interference. |
| Inaccurate SOC (State of Charge) reading | Incorrect battery capacity set in the app. | Access "Parameter Settings" in the app (password: 123456) and set the "rated capacity" to the actual capacity of your battery pack. |
| Over-charge/Over-discharge protection triggering prematurely | Protection parameters set too conservatively; Cell imbalance. | Review and adjust protection parameters in the app if necessary (consult battery manufacturer specifications). Allow the BMS to balance cells. |
| BMS heating excessively | High current draw; Inadequate ventilation; Faulty component. | Ensure the BMS is not operating beyond its rated current. Provide adequate airflow around the BMS. If heating persists, contact support. |
