Abstract

The invention relates to a storage unit (11) for electrical energy and a method for monitoring a storage unit (11) of this kind. The storage unit (11) has at least one storage element (1) for the short-term storage of electrical energy, for example a battery or capacitor. A means (3) for detecting physical variables, more particularly a pressure (p) or temperature (T), in the direct surroundings of the storage element (1) is allocated to the storage element (1), wherein the means (3) is designed to detect the physical variable, more particularly to detect a change over time of the physical variable, wherein the means (3) for detecting the physical variable is designed to provide a signal if a predefinable change over time of the physical variable is exceeded. Use in an intermediate circuitcapacitor in a rail vehicle is one advantageous use of the invention.

Description

technical field [0001] The invention relates to a storage unit for electrical energy and a method for monitoring such a storage unit. The invention also relates to a vehicle, in particular a rail vehicle. Background technique [0002] In the event of a short circuit or other failure, electrical energy storage units such as batteries or capacitors can be severely damaged. Therefore, monitoring the temperature rise in the immediate surroundings of such storage units is already a prior art. [0003] DE 10 2014 204 965 A1 describes a method for detecting abnormalities in battery cells and a short-circuit sensor system. [0004] US 2013-0122332 A1 also discloses a system with an integrated circuit, a pressure sensor and a communication device for integration in a battery unit. Contents of the invention [0005] A fast response to faults is particularly important for memory cells used to store electrical energy. It is therefore an object of the invention to quickly and relia...
