Banner BMS

Banner BMS is a professional battery management application designed to provide real-time monitoring, precise control, and comprehensive data analysis for battery systems via Bluetooth. Developed for engineers, technicians, and professionals in the field, this app serves as a reliable digital assistant for managing battery packs in electric vehicles, energy storage systems, industrial equipment, and other scenarios that depend on stable battery performance. It supports seamless Bluetooth pairing with BMS modules, enabling wireless access to battery data—ideal for on-site maintenance and hard-to-reach installation environments. With its user-friendly interface and powerful core features, Banner BMS allows users to assess battery health at a glance. The real-time monitoring module tracks key factors such as cell voltage, pack voltage, charge/discharge current, temperature (via NTC sensors), remaining charge capacity (RSOC), and cycle count. Each parameter is displayed with high precision, and the app supports multi-channel NTC temperature monitoring, allowing users to detect unusual temperature fluctuations in real time and avoid potential safety hazards such as overheating or undercooling.

Safety is a top priority for Banner BMS. The app features a comprehensive protection and alarm system that monitors 15 types of protection conditions (including cell over/undervoltage, packet over/undervoltage, overcurrent, short circuit, and MOS breakdown) as well as 12 types of alarm conditions (such as cell voltage deviation, high/low temperature alarm, and low capacity warning). Once an abnormal condition is detected, the app immediately triggers visual and audible alarms and logs the error information with a timestamp for subsequent analysis and troubleshooting.

In addition to Bluetooth-based real-time monitoring, Banner BMS offers comprehensive data analytics capabilities. It automatically logs historical battery operating data via Bluetooth, generates detailed reports on capacity degradation, cycle life, and temperature fluctuations, and supports data export for further analysis. The app also displays the FET control status in real time—including the on/off state of the charge/discharge MOSFET, the activation of the current limiting module, and the heating status—allowing users to remotely optimize battery operating strategies and extend its lifespan. The stable Bluetooth connection ensures low-latency data transmission with automatic reconnection in case of temporary signal interruption, preventing data loss during critical monitoring.

With a focus on practicality, Banner BMS extends Bluetooth functionality with offline data storage, ensuring that critical battery data is not lost even with a poor network or weak Bluetooth signal. Upon reconnection, the app synchronizes cached data to maintain a complete operating log. Whether for on-site maintenance, daily inspection or long-term battery management, Banner BMS uses a reliable Bluetooth connection to deliver professional, efficient and reliable solutions, thus maximizing battery performance and safety.
