We engineer high quality BMS applications that ensure safe, reliable, and optimized battery performance.
- Development of functional BMS software including monitoring, diagnostics, cell balancing, communication, and safety logic
- Integration with MCU drivers, hardware interfaces, communication stacks (CAN, LIN), and system level components
- Testing and validation across HIL, SIL, and real vehicle environments
- Algorithm refinement for voltage, temperature, and current accuracy under dynamic operating conditions
Our BMS implementations include industry grade safety and thermal strategies to protect battery health and prolong battery life.
- Over voltage, under voltage, over current, and short circuit protection logic
- Cell/pack level thermal management including thermal derating, cooling/heating control, and real time thermal monitoring
- Fault handling, limp home strategies, and safe state transitions
- Compliance with safety standards and OEM specific protection requirements
We support a wide range of automotive platforms and architectures.
- Integration with AUTOSAR Classic BSW modules (NVM, DCM, COM, DEM, etc.)
- RTE mapping, SWC development, and configuration using industry tools (Vector, EB, ETAS)
- Development for Non AUTOSAR architectures including custom middleware, platform abstraction, and proprietary OEM frameworks
- Support for legacy platform migration to modern BMS architectures
We deliver complete lifecycle support through all automotive development phases.
- Prototype and early sample development for hardware bring up and concept validation
- Design refinement, production software development, and feature enhancements
- Support during DV/PV testing, compliance audits, quality gates, and certification
- Full readiness for SOP, including documentation, traceability, tooling, and release management
AVIN Systems uses industry-standard tools and platforms to deliver robust and safety-compliant BMS solutions.
