Abstract
A method is provided for optimizing the operating lifetime of an energy storage system including a battery pack with a plurality of battery cells. The method includes: measuring the temperature of the battery pack by means of a sensor unit; and measuring at least one further parameter representing an indication of the operating lifetime of the battery pack. Furthermore, the method includes the steps of: detecting whether the parameter reaches a predetermined threshold value indicating that the battery pack is in a condition close to an end of its expected operating lifetime; and, in the event that the threshold value is reached, initiating heating of the battery pack, thereby increasing the temperature of the battery pack to a predetermined value so as to prolong the operating lifetime of the battery pack. A system for optimizing the operating lifetime of an energy storage system is also provided.
