About

Monitor, protect, & optimize electric vehicle (EV) battery performance with our battery management system solutions
  • Cell monitoring & balancing: Measure cell voltages and temperatures, balance the cells, and detect over- and undertemperature as well as voltage events.
  • Current sensing & coulomb counting: Measure current accurately for coulomb counting and over-current detection (OCD).
  • Battery control unit (BCU): Calculate battery states SoC, SoH, SoP, and SoS, communicate with the domain controller, and perform housekeeping and firmware updates.
  • Battery passport & event logging: Log vital parameters, track malfunctions, support warranties, and enable battery second life models. Enhance battery performance and proactively condition it.
  • Battery pack monitoring: Detect thermal runaway, monitor battery disconnection, isolation, and overcurrent. Trigger disconnection units when necessary.
  • Battery disconnection & protection: Ensure EV safety during parking, charging, and discharging. Disconnect from charger and monitor disconnection state when triggered by failures or vehicle being off.
  • Isolated communication: Transmit cell information reliably between high-voltage and low-voltage domains using wired (Iso-UART) and wireless (Low-power Bluetooth) topologies.
Enable faster time-to-market with complete automotive battery management system (BMS) chipset

Infineon's automotive BMS platform covers 12 V to 24 V, 48 V to 72 V, and high-voltage applications, including 400 V, 800 V, and 1200 V battery systems.

We offer a complete and scalable battery management system chipset, production-ready complex device drivers with integrated safety libraries, and support up to ASIL-D safety standards. The interoperability and flexibility help you to reduce design effort and speed up time-to-market for a wide range of applications such as:

  • Automotive
  • Energy storage
  • Construction, commercial and agricultural vehicles (CAV)
  • Low-speed electric vehicles
  • Electric two and three wheelers
48 V systems for EVs & mild hybrids
Enhance your automotive BMS with best-in-class robustness, compact design & lowest PPM rates

Infineon's highly integrated products significantly decrease the footprint and help the customers to reduce costs by minimizing printed circuit board size. Additionally, Infineon's zero-defect mindset is reflected in the lowest PPM rates in the market and significantly reduces vehicle downtime and returns.
