About this Gig
I offer complete design and development of automotive-grade Battery Management Systems (BMS) tailored for 18-cell LFP battery packs. My solution is based on the STM32 microcontroller, LTC6813 for accurate cell monitoring, and Quectel wireless modules for remote access and firmware updates. The BMS is fully compliant with AEC-Q100, AIS-156, and designed with DFM/DFT principles to ensure reliability, scalability, and ease of manufacturing.
My services include hardware schematic and PCB design with protections like surge, ESD, reverse polarity, and CAN isolation. I provide firmware development using RTOS, ensuring robust features like SOC/SOH calculation, CAN FD with SAE J1939, UDS protocol, and OTA firmware updates. The firmware is developed following MISRA C guidelines for safety-critical applications.
Whether you're building an electric vehicle, energy storage system, or industrial battery solution, I can support you from concept to a tested prototype. I also include test firmware and validation procedures. Let's collaborate to build a smart, safe, and efficient BMS for your application.

FAQ
What kind of battery packs is this BMS suitable for?
This BMS is designed for 18-cell LFP (LiFePO4) battery packs, commonly used in EVs, energy storage systems, and industrial applications.
Which microcontroller and monitoring IC are used in the design?
I use STM32 microcontrollers for firmware development and LTC6813 for accurate cell voltage monitoring with daisy chain support.
Does your BMS support communication protocols like CAN?
Yes, the BMS supports CAN FD with SAE J1939 protocol and is expandable for UDS (Unified Diagnostic Services) implementation.
Can I get wireless connectivity with OTA updates?
Absolutely. The system integrates Quectel wireless modules for remote diagnostics and OTA firmware upgrades.
Will I receive complete documentation with the design?
Yes. You will receive schematics, PCB files, firmware source code, CAN DBC files, user manuals, and test procedures.
Can this BMS design be used in real-world EV or industrial setups?
Yes. The design follows AEC-Q100, AIS-156, and DFM/DFT guidelines, making it suitable for production-grade applications.
Can you customize the BMS design based on my specific requirements?
Yes, I offer fully customized BMS solutions tailored to your specifications, including cell configuration, features, communication interfaces, protections, and wireless connectivity options. Just share your requirements, and I’ll build a solution that fits your application perfectly.
