- MOS Temp.: Displays the temperature of the MOSFETs, critical for thermal management.
- SOC (State of Charge): Indicates the remaining battery capacity as a percentage.
- Battery Pack Total Voltage: Shows the overall voltage of the entire battery pack.
- Output Current: Displays the current flowing in or out of the battery pack.
- Fault Code: An indicator for system errors or warnings. Refer to the app or a detailed fault code list for specific meanings.
- Average Voltage of the Battery: Shows the average voltage across all connected cells.
2. Mobile Application Monitoring
The JK BMS mobile application provides a more detailed view of battery parameters, including individual cell voltages, temperature readings, historical data, and advanced settings. Use the app for:
- Real-time monitoring of all battery parameters.
- Adjusting protection thresholds (e.g., over-voltage, under-voltage).
- Enabling/disabling specific functions.
- Firmware updates (if available).
Maintenance
Regular maintenance ensures the longevity and optimal performance of your BMS and battery system.
- Visual Inspection: Periodically inspect all wiring and connections for signs of wear, corrosion, or looseness. Ensure all terminals are secure.
- Cleanliness: Keep the BMS and surrounding area clean and free from dust, dirt, and moisture. Use a dry, soft cloth for cleaning.
- Firmware Updates: Check the mobile application regularly for available firmware updates to ensure your BMS has the latest features and bug fixes.
- Environmental Conditions: Ensure the BMS operates within its specified temperature and humidity ranges to prevent damage.
Troubleshooting
This section addresses common issues you might encounter with the JK BMS.
| Problem | Possible Cause | Solution |
|---|---|---|
| BMS not powering on / LCD blank | Incorrect main power connection, loose cable, or battery pack discharged. | Verify main battery connections (B+, B-). Check battery pack voltage. Ensure LCD cable is securely connected. |
| Battery not charging/discharging | Overcharge/over-discharge protection activated, overcurrent protection, or temperature protection. | Check battery voltage and current on the LCD or app. Allow battery to cool if temperature is high. Verify charger/load connections. Reset BMS if necessary (refer to app for option). |
| Cell voltage imbalance | Normal operation (active balancing in progress) or significant cell degradation. | Allow the active balancing function to work. If imbalance persists or is severe, inspect individual cells for health. |
| Bluetooth connection issues | Bluetooth disabled on phone, app not updated, or interference. | Ensure Bluetooth is enabled on your device. Restart the app and BMS. Try pairing again. Reduce distance to BMS. |
| Fault Code displayed | Specific error detected by the BMS. | Refer to the JK BMS mobile application for a detailed explanation of the fault code and recommended actions. |
