DETECTING MECHANICAL STRESS ACTING UPON A SYSTEM

Process for controlling a battery including energy storage cells, a controlling device, a sensor for detecting mechanical parameter or electrical parameter, a safety device, an interface for connecting the battery to an external device and electrical wiring. The process includes detecting parameter and eliminating the provision of electric energy from the energy storage cells, if a detected parameter reaches a predetermined threshold value. Battery including a energy storage cell, a controlling device, a sensor for detecting mechanical parameter or electrical parameter, an interface for connecting the battery to an external device, electrical wiring for transmitting electric energy between the at least one battery cell and the external device. The battery includes a safety device for eliminating the provision of electric energy from the energy storage cells, if a parameter detected by the sensor reaches a predetermined threshold value. System including a battery and an external device connectable to the battery.
