FIELD: energy storage.
SUBSTANCE: invention relates to a storage unit for electrical energy and a method for controlling such a storage unit. In addition, the invention relates to a vehicle, in particular a rail vehicle. The storage unit (11) contains at least one battery cell (1) for short-term storage of electrical energy, for example, a battery or a capacitor, while a means (3) for registering physical quantities, in particular pressure (p) or temperature (T), in the immediate environment of the battery cell (1) is correlated with the battery cell (1), and the means (3) for registering a physical quantity is made with the possibility, in particular, of registering a temporary change in the physical quantity, moreover, the means (3) for registering a physical quantity is made with the possibility of providing a signal when a given time change in the physical quantity is exceeded. The preferred use of the invention is carried out in the capacitor of the intermediate circuit of a rail vehicle.
EFFECT: increasing reliability of the operation of the unit.
