Abstract

The invention relates to a rechargeable battery (1) having a plurality of cylindrical cells (2) for storing electrical energy and at least one cooling device (4) for cooling or controlling the temperature of the cells (2), wherein the cooling device (4) has at least one coolant channel (5), at least one coolant inlet (6) and at least one coolant outlet (7), and at least one single-layer or multilayer film (8), which is arranged at least partly between the cells (2).

Description

technical field [0001] The invention relates to an accumulator with a plurality of cylindrical cells for storing electrical energy and at least one cooling device for cooling or temperature-regulating the cells, wherein , the cooling device has at least one coolant channel, at least one coolant inlet and at least one coolant outlet. Background technique [0002] The service life and efficiency and also the safety of rechargeable batteries for so-called electric vehicles, that is to say accumulators, also depend on the temperature during operation. For this reason, various designs for cooling or temperature-regulating the battery have already been proposed. The configurations can basically be divided into two types, namely air cooling and water cooling or generally liquid cooling. [0003] For water cooling, a cooling body is used in which at least one coolant channel is formed. The heat sink is arranged between the individual modules of the battery or on the modules. A m...
