FRIWO offers battery solutions with communication interfaces in its standard product range: Built-in SMbus interfaces for data transfer allow for example to indicate the remaining battery runtime or the maximum available capacity. For this purpose, all limit values can be adjusted in an optimal way to the cells used. This is of great importance, especially for safety-related or medical applications.

The SMbus is based on the widely spread I²C bus protocol which is used for communication between separate functional units. The bit rate of this 2-wire bus can be up to 100Kbit/s. To achieve this, FRIWO uses premium components from Texas Instruments. These can be implemented in a very space-saving way on the battery management system (BMS): there are semiconductor ICs available, consisting of protective circuit ICs with integrated SMbus interface. Also the combination of analogue-front-end (AFE) for analysis of battery parameters and separate communication IC provide for a safe and exact data communication matching perfectly with the Samsung battery cells.

Within the FRIWO standard portfolio, modern battery management systems let battery packs of medium and big size configurations (4S1P to 10S3P) become intelligent and adaptable.
