Advanced Battery Management System (BMS)
Infineon delivers a complete, safety-certified and highly integrated BMS solution designed to improve battery safety, performance, robustness, and time-to-market. Our chipset and software stack work together to optimize energy accuracy, lifecycle reliability, and system efficiency for EVs and large-scale battery-powered systems.
What Is a Battery Management System (BMS)?
A Battery Management System is the intelligence layer behind every modern EV or energy storage battery. It monitors, protects, and controls the battery pack to ensure safety, long lifespan, and optimal performance across all operating conditions.
- Monitors cell voltages, temperatures & current flow in real-time.
- Ensures safe charging, discharging & thermal stability.
- Balances cells for longer battery life and higher efficiency.
With Infineon’s complete BMS chipset and production-ready software, customers can accelerate development and meet stringent automotive-grade safety requirements up to ASIL-D.
Key Features & Benefits of Our BMS Offering
A complete chipset paired with production-ready complex device drivers and integrated safety libraries supporting up to ASIL-D compliance.
Highly integrated components reduce PCB size, simplify layouts, and help OEMs lower system-level cost without compromising reliability.
Designed to improve battery lifetime, data accuracy, and operational stability across demanding environments.
Seamless interoperability between hardware and drivers reduces development effort, integration complexity, and validation cycles.
Infineon’s Zero-Defect mindset ensures the industry’s lowest PPM rates—reducing failures, warranty claims, and vehicle downtime.
Why a High-Quality BMS Matters
- • EV safety, battery health, and lifecycle performance all depend on the accuracy and reliability of the BMS.
- • A robust BMS prevents thermal runaway, overcharging, short circuits, and deep discharge failures.
- • Cell balancing ensures each cell ages uniformly and delivers consistent range and efficiency.
- • Accurate state-of-charge (SoC) and state-of-health (SoH) measurements reduce range anxiety and improve performance prediction.
- • Automotive-grade BMS ensures compliance with global safety standards including ASIL, ISO 26262, and OEM-specific requirements.
- • A high-quality BMS directly reduces warranty claims, field failures, and repair intervals.
How to Optimize a Battery Management System
- ✔️ Use a chipset with integrated safety and monitoring features to simplify validation.
- ✔️ Choose high-accuracy sensing solutions for voltage, temperature, and current measurements.
- ✔️ Implement robust cell-balancing strategies for improved lifecycle and pack stability.
- ✔️ Enable predictive diagnostics to detect anomalies early and enhance reliability.
- ✔️ Ensure hardware–software interoperability to reduce development overhead.
- ✔️ Adopt secure communication interfaces and encryption for data safety.
- ✔️ Validate the entire BMS under extreme temperatures, loads, and charging conditions.
