How to Use the Host Computer

October 8, 2025

When debugging, maintaining, or configuring lithium batteries, using host computer software is the most direct and effective method. This software not only monitors the battery's operating status in real time but also allows for parameter settings, fault diagnosis, log export, and other operations, making it suitable for a wide range of scenarios.

I. What is host computer communication?

Host Computer refers to the computer program that exchanges data with the battery BMS through serial port, USB or other communication interface. It mainly includes:

 

- BMS-vendor PC tools (e.g., JBD Tools)

👉Download the manual to learn about the detailed guide to connecting JBD with the host computer software

- Self-developed visualization platform (such as HMI, data acquisition software).

 

These tools allow for detailed configuration and monitoring of batteries.

II. Host-PC Connection Methods

Different battery models may have different interfaces and connection methods to the host computer. It is recommended to check the relevant manuals.Currently supported battery models include 48V 100Ah Server Rack Battery

The core theme of this article series is “Intelligent Battery Communication,” focusing on the communication functions and technologies of the 48V 100AH server rack battery and its related devices. It covers master-slave communication, upper computer communication, mobile APP communication, and inverter communication, aiming to help users understand and apply these technologies.

1.

Real-Time Monitoring

Pack voltage, current, SOC (State of Charge)

Single cell voltage, temperature, balancing status

Protection states (over-voltage, under-voltage, over-current, over-temperature, etc.)

2.

Parameter Configuration (password-protected)

Charge/discharge voltage and current thresholds

Temperature protection limits

Battery chemistry type and capacity settings

⚠️Caution:

 

Some parameters need to be adjusted with caution, especially the protection voltage and current limit. Incorrect modification may cause the battery to fail to charge or prematurely protect itself.

3.

Fault Diagnosis & Data Export

View historical fault codes and protection logs

Export real-time monitoring data to CSV files

Certain software versions support firmware upgrades

III. Troubleshooting & Solutions

Unable to connect /recognize COM port

A: Check whether the COM port is recognized . If not, reinstall the USB driver and check whether the connection is correct.

Q: The connection is successful but the data is garbled or missing

A: The baud rate is set incorrectly . Reset the baud rate according to the corresponding product manual.

Q:Parameters cannot be changed

A: Insufficient privileges. Parameter modification usually requires logging in with an admin or high-level user account.

Host-PC communication is a vital tool for battery system commissioning. Mastering the connection and operation procedures greatly improves work efficiency and diagnostic accuracy. We recommend using the dedicated adapter cable and the official debugging software (available on the relevant product page) to ensure stable and safe communication.
