Our BMS platform guarantees up to ASIL D safety level for hardware and software, and supports diverse applications such as industrial, energy storage, commercial and agricultural vehicles (CAVs), low-speed electric vehicles, and electric two and three wheelers.
The 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.
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.

By the end of this decade, the majority of new cars sold around the world are expected to have a partially or fully electric drivetrain. Battery management systems have a great impact on the range, cost, and service life of electric vehicles, which makes them a key success factor for this mobility revolution. Furthermore, they play an essential role when it comes to second-life concepts that allow former EV batteries to be used as flexible storage for renewable energy, for example. Dr. Clemens Mueller exclusively explains in-depth market trends and challenges, provides details on Infineon products and solutions and introduces the new BMS-IC TLE9012AQU.
