Tasks of Battery Management Systems

Independent of the battery type and the applieation, the structure of the BMS is always broadly the same. The functions of a BMS can be split into the following tasks  

The calculated control parameters are transmitted via an interface to the control units, such as the charger and the load. The task with the highest priority is safety management. Any critical failure must be detected by this task and substitute 

Depending on the application and the battery chemistry, the functions within the tasks are different. For small batteries, some of the Ksted functions are available as single- or multiple-chip solutions. For example, lithium-ion battery packs for cellular phones and laptop computers contain, as a minimum, a safety-management function. In the case of larger battery systems, the BMS is more complex and must be individually developed for the battery technology and the application.
