FMD (Fremont Micro Devices) has released a new BMS+MCU subsystem specifically designed to help mobile power banks meet the strict "status visibility and data traceability" requirements of the new national standards. By acting as an external add-on for 2-5 cell packs, this solution helps manufacturers upgrade without scrapping their current fast-charging infrastructure.
Inside, the system relies on a dual-chip setup: the FT925D1A63 BMS chip provides precision monitoring (SOC/SOH/cycles) and hardware-level protection—including a smart feature that automatically lowers over-voltage protection (OVP) thresholds as cells age. The FT32F0XX MCU (ARM Cortex-M0) serves as the hub, aggregating battery data and pushing it to various displays, Bluetooth apps, or PC web interfaces.
This modular approach is a game-changer. It offers a scalable platform where manufacturers can choose the level of integration—from basic compliance for entry-level models to full-featured visualization for high-end devices—offering a perfect blend of efficiency, safety, and market-ready innovation.
