How to design a battery management system

Infineon integrated circuits and designs help you lay out your battery management system. Careful design considerations on charging and discharging processes on battery protection and cell monitoring will support you throughout your design. In fact, our design support solutions can help you overcome design challenges and support your success in developing more efficient, longer lasting, and more reliable battery-powered applications. Our tools are created by engineers for engineers and will support you in every phase of your design, from comparing the different products to simulations, and of course ready-to-use reference designs.

Why are battery management systems (BMS) needed and how do they work?

Battery management systems (BMS) are electronic control circuits that monitor and regulate the charge and discharge of batteries. The battery characteristics to be monitored include the detection of battery type, voltages, temperature, capacity, state of charge, power consumption, remaining operating time, charging cycles, and some more characteristics.

Tasks of smart battery management systems (BMS)

The task of battery management systems is to ensure the optimal use of the residual energy present in a battery. In order to avoid loading the batteries, BMS protects the batteries from deep discharge and overvoltage, which are results of extreme fast charge and extreme high discharge current. In the case of multi-cell batteries, the battery management system also provides a cell balancing function, to manage different battery cells having the same charging and discharging requirements.
