How to use the Jikong BMS app

BMS od Jikong a mobilní aplikace



Reliable communication between your battery management system (BMS) and your batteries is key to their efficient operation and longevity. Modern solutions such as the Jikong BMS app from Chengdu Jikong Technology greatly facilitate this data exchange by linking to a mobile app. How does the app work?

Jikong BMS and linking to the mobile app

The Jikong BMS app is a convenient way to monitor battery status, set parameters and actively manage cell balancing, i.e. the charging and discharging of individual batteries. Thanks to integrated Bluetooth technology, the app easily connects to the battery system and enables efficient BMS management without the need for complicated cable connections.

Features of the Jikong BMS app

    • Real-time parameter display: overview of key values such as battery voltage, current, state of charge (SOC) or individual cell voltage.
    • Active balancer settings:
    • Active balancing ensures all cells are evenly conditioned, extending overall battery life and minimizing battery aging.
    • User-friendly interface: Intuitive and easy-to-use design makes it quick to get started and simple to master battery management.

You connect the device in the top left corner of the app, the security password is 1234. You will be also prompted to enter the password when editing important parameters. Use the factory security password 123456 to make these changes .

Where to download Jikong BMS app?

The Jikong BMS app provides users with a convenient way to manage and monitor their battery systems directly from their mobile devices. Designed for easy use on smartphones or tablets, the app allows quick access to battery information and parameter settings from anywhere. For Android users, the app is available for download in the Google Play store. Those using iOS devices can download the app from the Apple Store. For those who prefer to work on a larger screen or need more comprehensive management of their systems, a desktop version of the app is also available for PC.



Simple instructions to get started with the app

This procedure will help you set up and start using the application quickly and efficiently:

    • Download the app to your mobile phone.



    • Connect the protection board and battery pack. Make sure the last power cable is connected to the main positive pole. The total voltage of the battery pack must be above 20V before starting.



    • Activate the BMS: Use the display activation button or the additional switch to activate the BMS.



    • Turn on Bluetooth: Make sure Bluetooth is turned on on your mobile phone, then open the app.



    • Locate the device: Click in the top left corner of the app to locate the device. Then click on the device name to connect. The default password for the connection is 1234.



    • Set parameters. This process requires a password, which defaults to 123456. Easily set the number of cells and battery type.



    • Check Battery Status: Once the parameters are set, return to the real-time status page and check the battery status. If no error message is displayed and operation is normal, blue indicates the highest voltage while red indicates the lowest voltage.

Problems with Jikong BMS app

Not loading:

  • Make sure the last "B+" cable is connected to the positive terminal of the battery.
  • Start the device after charging and check if the charger voltage is higher than 4V at the battery pack.
    • Check the
  • charger output voltage.

Incorrect voltage::

  • Measure the total voltage of the battery pack with a multimeter and enter this value in the "voltage calibration" section of the parameter settings.

Incorrect current:

  • Connect the AWG wires P - and B - from the protection board in parallel.
  • If they are not connected correctly, a current measurement error will occur.
  • Measure the actual current of the battery pack with a clamp multimeter and enter this value in the "current calibration" section of the parameter settings.

Incorrect capacity:

  • The initial estimate of capacity from the gauge voltage when the protection board is first turned on is inaccurate.
  • After the protection board is discharged to the shutdown voltage and then fully charged, the capacity is calibrated. The charging process should not be interrupted.

Mismatch between the designed and actual number of strings:

  • Check that the "number of units" in the parameter settings is set correctly.
  • If two or more strings in the module do not display voltage, check that the measurement cable is not disconnected.
