Image: QR code for JIKONG BMS APP download.
Alternatively, search for "JIKONG BMS" in the APP STORE for iOS or "JK BMS" in the Google STORE for Android.
6.2. Activació del dispositiu i configuració inicial
- Before starting the protection board, ensure the balance cable is properly connected and that P- and B- are correctly connected. Verify the protection board is securely fixed to the battery core. Incorrect connections can lead to malfunction or damage.
- After confirming connections, power on the protection board. The BMS does not have a power-on switch; it is designed for charging activation mode. The charger voltage ha de ser 2V superior al volum de la bateriatage. After battery assembly, connect the charger to activate the protection board.
- The protection board also supports key activation (via an additional switch) and display activation (if a display screen and button are installed, simply plug the cable into the display interface and press the button).
- Activa el GPS i el Bluetooth al teu telèfon mòbil.
- Ensure your mobile Bluetooth is on, then open the APP. Click the top left corner of the APP to search for devices. Click on the device name to connect (default password: 1234).
- For the first startup, parameters need to be set. Setting requires a password (default: 123456). Simply set the number of units (cells) and battery type.
- Once parameters are set, return to the real-time status page to check battery status. Ensure no error messages are prompted and operation is normal. Blue indicates the highest voltage, red indicates the lowest voltage.
6.3. Configuració de paràmetres
Users can set the balance trigger pressure difference (mV) in the APP's parameter settings. When balancing is enabled, it automatically activates if the pressure difference between any two battery strings exceeds the set value, and deactivates when it falls below the set value. The default balance current is 1A. Users can adjust the balance current based on battery capacity, ensuring it does not exceed 0.2C of the battery capacity (C). If balancing is not needed, it can be turned off in the BMS control page of the APP.
For detailed instructions on setting protection board parameters, please refer to the original user manual PDF.
7. Característiques de protecció
The JIKONG BMS offers comprehensive protection for your battery system:
- Charge Overvoltage Protecció: Prevents overcharging by shutting off charging when any cell exceeds the set voltage. Resumes when all cells are below the recovery voltage.
- Descàrrega Undervoltage Protecció: Prevents over-discharging by shutting off discharge when any cell falls below the set voltage. Resumes when all cells are above the recovery voltage.
- Charge Overcurrent Protection: Protects against excessive charging current. Triggers after a set delay and resumes after a release time.
- Discharge Overcurrent Protection: Protects against excessive discharge current. Triggers after a set delay and resumes after a release time. (Note: Max continuous discharge current should not exceed 100A).
- Protecció contra sobretemperatura: Shuts off charging/discharging if battery temperature exceeds set limits. Resumes when temperature returns to safe levels.
- Protecció de baixa temperatura: Shuts off charging if battery temperature falls below set limits. Resumes when temperature returns to safe levels. Heating function is recommended for cold environments.
- Protecció contra curtcircuits: Automatically protects against short circuits. Delay and recovery times can be configured via the APP.
- Discharge Precharge Function: Optional feature with a default precharge time of 5 seconds. Can be enabled or disabled as needed.
- Interruptor d'emergència: Provides 30 minutes of continued charge/discharge operation in emergency situations (e.g., over-temperature, over-discharge) to prevent immediate power loss.
- Son intel·ligent: Reduces self-consumption by entering sleep mode when charge/discharge current is below 1A for 26 consecutive hours. Can be reactivated via button or charger.
- Communication Function: Supports optional CAN/RS485. Address and protocol can be configured via the APP.

8. Manteniment
The JIKONG BMS is designed for low maintenance. Regular checks include:
- Integritat de la connexió: Periodically inspect all wiring, especially balance cables and main power connections (P- and B-), for secure and correct attachment.
- Paràmetre Review: De tant en tant review the parameters set in the APP to ensure they align with your battery configuration and usage patterns.
- Actualitzacions de firmware: Check the JIKONG BMS APP for any available firmware updates to ensure optimal performance and access to new features.
- Inspecció física: Ensure the BMS is securely mounted and free from physical damage, moisture, or excessive dust accumulation.
9. Solució De Problemes
If you encounter issues with your JIKONG BMS, consider the following:
- BMS Not Activating: Assegureu-vos que el carregador voltage és almenys 2 V superior al volum de la bateriatage. If using a display/button, ensure it's connected and the button is pressed.
- Balancing Issues: Check the balance trigger pressure difference setting in the APP. Ensure the balance current is appropriate for your battery capacity.
- Protection Triggered: If a protection (overvoltage, minvartage, overcurrent, overtemperature, short circuit) is triggered, the BMS will shut down charging/discharging. Identify the cause (e.g., high/low voltage, excessive current, temperature) and rectify it. The APP will provide alarm notifications.
- Short Circuit Protection on Startup: If short circuit protection triggers when connecting a charger or load, ensure external wiring is correct. For loads with large capacitance, increasing the short circuit protection delay in the APP may help.
- Communication Problems: Ensure Bluetooth is enabled on your mobile device and the APP is correctly connected. For CAN/RS485, verify the address and communication protocol settings.
- La funció de calefacció no funciona: Ensure your BMS model supports heating (check for "Heat" in the model name). Verify the heating film or charger connections. Check the low-temperature protection settings in the APP.
10. Consells d'usuari
- Always double-check all wiring connections before powering on the BMS to prevent damage.
- Utilize the mobile APP to regularly monitor your battery's health and adjust settings as needed for optimal performance.
- For cold environments, consider enabling the heating function to maintain battery efficiency and longevity.
