Abstract

The invention relates to an accumulator (1) having at least one cell (3) for storing electrical energy and at least one cooling device (2) for cooling or controlling the temperature of the cell (3), the cooling device (2) comprising at least one coolant channel (5). The cooling device (2) comprising at least one single- or multi-layer film (4, 9) having at least one sensor element (17).

Description

technical field [0001] The invention relates to an accumulator with at least one battery cell for storing electrical energy and at least one cooling device for cooling or temperature-regulating the battery cell, wherein the cooling device has at least one Coolant channels. Background technique [0002] Also for so-called electric mobility (E-mobility), the service life and efficiency and safety of rechargeable batteries, ie accumulators, also depend on the temperature during operation. Excessive temperatures can become dangerous for batteries and drive units in electric and hybrid vehicles. For this reason, various concepts have been proposed for cooling or tempering the battery. Basically, the concepts can be divided into two types, namely air cooling and water cooling or liquid cooling in general. For monitoring the heat release, for example from EPCOS AG (https: / / de.tdk.eu / tdk-de / 190976 / tech-library / artikel / applications---cases / applications--- cases / bodyguards-fuer-ba...
