The arrangement tests the safety of systems which contain an electro-chemical energy storage, such as a battery, which provides, at least occasionally, the electric energy for the execution of a security process. The electro-chemical energy storage is equipped with a permanent identification carrier, through which the characteristic sizes and the fitness of the energy storage in the system can be determined. The energy storage may be arranged in a vehicle, and serves for a supply of its brake system. The identification carrier is preferably an electronic memory component, which contains information, e.g. about manufacturer, product type and date, expire date, etc.
