Model-Based Development of Algorithms for a Battery-Management System
Due to their high power density and volumetric energy, lithium batteries are increasingly being employed as the source of energy in vehicles and mobile devices. Often, however, the individual cells have to be series-connected in order to reach the required supply voltage. As these cells, due to different production conditions, inevitably will differ in parameters (capacity, internal resistance, etc.), the result will be varying states of charge in these cells during operation. Because lithium batteries are damageable by a cell voltage that is either too high or too low, it is impossible to assure safe operation of the battery pack. So, in order to make lithium batteries operate safely, a battery management system is employed. Our contribution is about generating and applying a simulation model for the model-based development of functions for this battery-management system.
