RECHARGEABLE ENERGY STORE

摘要

The invention relates to a rechargeable energy store designed either as an electrochemical energy store having a housing in which a positive electrode and a negative electrode are received, an electrolyte being present between said electrodes, or as a capacitor module having a plurality of cells of double-layer capacitors and/or hybrid capacitors connected to each other, wherein, if the rechargeable energy store is designed as an electrochemical energy store (1), a phase change material (8) is disposed in the housing (2) for controlling the temperature of the energy store (1), wherein said material absorbs at least part of the heat emitted by the energy store (1) when charging or discharging, or, if the rechargeable energy store is designed as a capacitor module (11, 15, 19, 24, 32, 40, 44), comprising a phase change material (14, 17, 21, 30, 31, 39, 43, 46) in contact with the cells (12, 16, 20, 25, 26, 33, 41) for controlling the temperature of the cells (12, 16, 20, 25, 26, 33, 41), absorbing at least part of the heat emitted by the cells (12, 16, 20, 25, 26, 33, 41).
