Automotive battery passport and event logging
Log and monitor battery parameters to ensure safety, optimize charging, and increase lifetime
The BMS records vital battery parameters even when the battery is off, providing immediate information on cell capacity, SOC, SOH, power consumption, and remaining operating time. It enables mission profile extraction for performance optimization and serves as a flight recorder for tracking malfunctions and supporting warranties.
Ensure safety and optimize efficiency with highly secured solutions
The BMS records vital parameters such as voltage, current, temperature, and others throughout the battery lifecycle, even when the battery is switched off, to fulfill the following functionalities:
- Immediate derivation of information on actual cell capacity, SOC, SOH, power consumption (charge/discharge), remaining operating time of cell, etc.
- Later extraction of typical mission profiles. Together with advanced machine learning algorithms, the battery could be tuned for performance or proactively preconditioned when an acquired load scenario occurs.
- As a flight recorder-like black box that continuously records all relevant battery data to trace the root causes of malfunctions, clarify warranties in case of (hazardous) incidents or simply support new business models based on the "pay-per-use" principle.
Product portfolio

The most energy efficient, high density, and reliable memories
Key features of Infineon's EXCELON™ F-RAM:
- Low-pin-count Quad SPI interface
- 54 MB/s throughput at 108 MHz frequency
- NoDelay™ writes
- 100 trillion read/write cycles of endurance
- 160 years data retention at 50°C
- AEC-Q100 and functional safety (ISO 26262) compliant
- 200x less energy than EEPROMs
Advantages of F-RAM over traditional NVM:
- Fast writes at full interface speed
- Instant nonvolatility without write delays where traditional memories have delays of 5 ms or more before data becomes nonvolatile
- Pending data is lost in NVM unless the system has enough capacitance or extra batteries to keep the system running until the data is stored
- F-RAM offers virtually unlimited endurance with 100 trillion read/write cycles while traditional memories typically have less than 1 million cycles of endurance
- Complex wear-leveling routines and increased density are needed to extend the lifetime of traditional memories
