METHOD, COMPUTER PROGRAM, ELECTRONIC STORAGE MEDIUM AND DEVICE FOR DETECTING THE BREAKDOWN OF AN ENERGY RESERVE UNIT

A method for recognizing the breakdown of an energy reserve device of at least two energy reserve devices of a device for protecting the occupants of a vehicle. The method includes: charging the at least two energy reserve devices to a test voltage level; ascertaining an ambient temperature of the at least two energy reserve devices; acquiring the (overall) capacitance of the at least two energy reserve devices; recognizing the breakdown of an energy reserve device as a function of a floating mean value, which is a function of the ascertained ambient temperature, for the (overall) capacitance and of the acquired (overall) capacitance; updating a floating mean value as a function of the ascertained ambient temperature and the acquired overall capacitance.
