Multi-module batteries
What are multi-module batteries battery packs?
Multi-module batteries consist of several single-battery modules which are connected in series or parallel. Typically large-format Lithium-ion battery packs consist of modules that are assembled together. Multi-module batteries are typical for applications with high-voltage batteries including automotive, e-forklifts, material handling, automated guided vehicles, e-boats, residential and utility size energy storage systems and UPS.
To ensure the optimal use of the energy, to control charging and discharging processes and to monitor each cell‘s state of Health (SoH) the Battery Management System (BMS) monitors and controls all processes impacting the battery.
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.

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.
