Problems solved by technology

Since the electrolyte used in storage batteries is usually conductive, this can lead to short circuits inside the storage module in unfavorable situations
Therefore, the functionality of all storage modules may no longer be guaranteed

Embodiment Construction

[0024] figure 1 Exemplarily shown is a schematic front view of the storage module 1 of the present invention. The shown storage module 1 has by way of example six storage cells 10 , 11 , 12 , 13 , 14 , 15 which are arranged in two rows one above the other. The installation of the storage module 1 , for example in a motor vehicle, can take place with reference to the direction of gravity marked with "S". In practice the storage module may have a different number of storage batteries than that shown. If storage batteries are mentioned in the following exemplary embodiments, these are also to be understood as double-layer capacitors.

[0025] The storage cells 10 , . . . , 15 have a—again only exemplary—circular cross section, but other cross-sectional shapes are also possible in principle. Each of the storage cells 10, . . . , 15 includes first and second terminals of different polarity. exist figure 1 On the front side visible in , storage cells directly adjacent to each o...

Abstract

The invention relates to a storage module (1) for voltage supply, in particular for a motor vehicle, comprising a plurality of storage cells (10, 11,..., 15), each having a first and a second connecting terminal of differing polarity and a valve (30, 31,..., 35), via which an internal pressure present in a storage cell (10, 11 15) can be reduced and electrolyte can escape from the storage cell (10, 11,..., 15). The storage cells are electrically interconnected via the connecting terminals to form the storage module (1). In order to receive and bind leaking electrolyte, an absorbent layer (50) is disposed adjacent to and / or in the region of the valve (30, 31,..., 35) of a respective storage cell (10, 11,..., 15).

Description

technical field [0001] The invention relates to a storage module for supplying electricity, in particular to a motor vehicle, comprising a number of storage batteries each having first and second connection terminals of different polarity and valves. The storage battery is electrically connected to the storage module through the connection terminal. Via the individual valves, the internal pressure present in the storage cell can be reduced and electrolyte can be drained from the storage cell. Background technique [0002] Storage cells of storage modules of the kind described above usually have a valve in the form of a standard break point. This non-closable standard break point, which can be actuated once by an overvoltage inside the storage cell, enables excess electrolyte to be drained from the interior of the storage cell during aging of the storage cell. Since the electrolytes used in storage cells are generally conductive, this can lead to internal short circuits in ...
