STM32 BMS Embedded Firmware SDK (Integrated µC/OS-III RTOS)

Application Scenarios

• Commercial Deployment: Electric Vehicles (EV), Grid-Scale Energy Storage Systems (ESS), and Power Tools. Up to 256 battery cells in series.
• R&D & Prototyping: Rapid corporate product prototyping, bypassing the most tedious phases of embedded development to achieve instant project rollout.
• Academic & Institutional: Deep-level hardware research and advanced algorithm testing for university and enterprise labs.

Perpetual License

• No Subscriptions. No Recurring Fees.

Technical Highlights

• High-Performance MCU Architecture: Natively optimised for the industry-standard STM32F4 / F7 series microcontrollers. Offers plug-and-play adaptability for both NMC (Lithium Nickel Manganese Cobalt) and LFP (Lithium Iron Phosphate) battery chemistries.
• Integrated Real-Time OS (µC/OS-III): Unlike basic bare-metal code, this firmware runs on a fully integrated µC/OS-III kernel. It guarantees deterministic task scheduling, preemptive multitasking, and mission-critical reliability under extreme industrial loads.
• Comprehensive BMS Algorithm Suite: Comes out-of-the-box with complete, production-tested functional modules:
  • Advanced SOC (State of Charge) & SOH estimation loops.
  • Intelligent active/passive cell balancing management.
  • Strict over-voltage, under-voltage, and over-current hardware protection triggers.
  • Multi-point dynamic thermal monitoring (NTC).
• Massively Scalable Daisy-Chain Topology: Built-in multi-slave communication protocols capable of handling complex daisy-chain hardware architectures. Seamlessly scalable to monitor and manage up to 256 battery cells in series.
• Industrial-Grade Code Standards: Engineered for effortless secondary development. Features a strictly modular design with >85% comprehensive code comment coverage. The architecture is clean, highly readable, and ready for immediate commercial deployment.

(Note: This is a digital source code developer asset. Once delivered, it provides full transparency into the architecture for your engineering team to modify as needed.)

Globally Standardised & AI-Ready Codebase

• This framework is engineered for international R&D teams. All core architectures, variable namings, function calls, and the vast majority of inline comments are written in standard Technical English. > You may occasionally find localised annotations (in Chinese) specifically detailing regional hardware quirks or proprietary battery protocols. These rare localised comments are completely non-blocking and can be instantly translated using AI tools like GitHub Copilot or ChatGPT, giving your team unique insights into top-tier Asian battery supply chain configurations.

IMPORTANT SOFTWARE REQUIREMENTS

• This is strictly an embedded firmware project designed for the ARM Cortex architecture. To successfully open, compile, and modify the source code, you will need ARM Keil uVision (MDK-ARM) installed on your workstation.
