BAT-BMS

BAT-BMS is a powerful utility for Android designed for battery management. It enables users to track the cycle life of individual battery packs and provides real-time monitoring of key parameters, including state of charge (SOC), voltage, and charge/discharge current. The software also displays the voltage of individual battery cells. By connecting via Bluetooth, users can monitor battery data and perform various control operations. It is particularly useful for engineers conducting voltage measurements, and on compatible devices, it supports remote control of charging and discharging functions.

Features

No need for a separate battery monitor

Wirelessly connect to each battery from your phone

Track Cycle Life on each battery

Display SOC, voltage, charge and discharge current, cycle life, cell voltage, and temperature

The phone needs Bluetooth 5.0 with Bluetooth Low Energy functions

Operating distance: less than or equal to 15 meters

The application can connect multiple batteries simultaneously, allowing you to view the data of another battery by switching between left and right pages

If you wish to connect the battery to another mobile phone, please close the app on the first mobile phone

Highlights

Connect wirelessly to compatible Bluetooth-enabled lithium batteries using Bluetooth 5.0 Low Energy technology.

Monitor real-time battery information including State of Charge (SOC), voltage, charging current, discharging current, cycle count, individual cell voltages, and battery temperature.

View multiple compatible battery packs from a single device and switch between connected batteries within the app.

Eliminate the need for a separate battery monitor by displaying detailed BMS information directly on your Android phone or tablet.

Advantages and disadvantages

Pros

Per-cell voltage display for granular imbalance detection

Bluetooth Low Energy connectivity with up to 15-meter range

Manages multiple battery packs within a single interface

FAQS

Can the app monitor multiple batteries simultaneously?

Yes. The app can connect to multiple batteries; you can view data for different batteries by swiping left or right within the app interface.

What battery data does the app display?

The app displays the State of Charge (SOC), battery pack voltage, charge/discharge current, individual cell voltages, temperature, and cycle life. For some batteries, the app also allows you to enable or disable the charge/discharge circuit and provides an advanced mode for adjusting parameters.

What should I do if the app fails to connect or crashes?

Troubleshooting steps: 1) Ensure that Bluetooth is enabled on your phone and that the necessary permissions have been granted (on Android/iOS). 2) Move closer to the battery (within 15 meters). 3) Completely close the app on any other connected mobile devices. 4) Restart your phone and reopen the app. 5) Reinstall the app if necessary. If the issue persists, please contact support (see below). Some users have reported intermittent issues while the developers work on optimizing the app.

Does the app collect or share my data?

We do not collect any user data, nor do we share data with any third parties. The developers may update privacy and data protection measures; please check the app's privacy policy link on the app store page for the latest details.

Summarize

BAT-BMS for Android is a companion app for smart Bluetooth lithium batteries equipped with a compatible Battery Management System (BMS). Developed by SHENZHEN GRENERGY TECHNOLOGY CO., LTD., the app connects directly to supported battery packs over Bluetooth Low Energy (BLE), allowing users to monitor battery health and operating status without requiring a separate physical battery monitor. It is intended for use with compatible lithium battery systems used in applications such as RVs, boats, golf carts, solar energy storage, and other off-grid power systems.
