Single-module batteries above 60V
A cell is the smallest, packaged form of a battery. A battery module consists of several cells that are assembled in a series or in parallel. A multi-module battery (battery pack) is created by connecting several modules together. Single-module batteries are typical for applications with voltage ranges not exceeding the 150 V, such as battery-powered tools, vacuum cleaners, multicopter, robots, e-scooters, e-bikes, low voltage telecom, and server UPS. In the case of multi-module batteries, the Battery Management System (BMS) monitors and controls all processes impacting the battery.

ExcelonTM F-RAM™, like any other nonvolatile memory technology, is subject to physical degradation that can eventually lead to device failure if not addressed appropriately. F-RAM write/read endurance and data retention are the two end-of-life (EoL) parameters to specify its reliability and performance in a system. Learn more about the F-RAM data retention performance at various operating temperatures and find a method and guidance to accurately calculate the system’s EoL based on its operating temperature profile. Check the application note.
Battery protection enhances the useful operating life of lithium-ion batteries by protecting the battery pack against charge current, discharge current, and pack short fault conditions. Learn more about battery protection.
Besides current, voltage and temperature measurements advanced analytics are performed on pack-level with respect to thermal, electrical and mechanical strain: Highly accurate pressure sensing allows to observe the possible extension of cell housing as a result of overload/-charge condition or detection of mechanical impacts on the pack‘s mechanical structure. Sensing of evaporated CO2 from the cell’s electrolyte as a result of cell aging or overstress could be a vital indicator for battery health. Finally, a combination of the pressure of condition sensors allows for the detection of unauthorized pack manipulations e.g. for modification or replacement of cells by measuring variations in pressure or 3D magnetic structures.
F-RAM: Instantly non-volatile Excelon F-RAM with the lowest power operating at 20, 50, or 106MHz, capacity from 2Mb to 8 Mb. Read/write performance 4kb/s to 4 Mb/s using serial SPI / I2C or 64 kb/s to 4Mb/s for 8-/16-bit parallel access. Excelon F-RAM provides an endurance of 1e14 cycles and 100 years of data retention. It is radiation tolerant and has a low SER. The combination of high endurance, long data retention, and fast access makes it a perfect fit for non-volatile data logging.

Getting the most out of batteries. By the end of this decade, the majority of new cars sold around the world is 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.
