Embodiment Construction

[0050] exist figure 1 A perspective view of a single prismatic storage cell 10 of an energy storage module 1 can be seen in the figure, the entirety of which will be shown later. Storage battery 10 typically includes one or more individual electrochemical cells that are not visible within storage battery 10 in the view selected here. The storage cell 10 has a connection terminal 11 of the first polarity and a connection terminal 12 of the second polarity on the front side 13 . No connection terminals are provided on the rear side 14 of the storage cell 10 , which is not shown in the illustration. One of the connection terminals 11 , 12 , typically the positive pole of the storage battery, can be electrically connected to the casing of the storage battery 10 .

[0051] Since a plurality of storage cells 10 are stacked in at least one sequence, arranged one behind the other, in the energy storage module 1 according to the invention, at least opposite main planes 15 , 16 are pr...

Abstract

The invention relates to an energy storage module (1) for a device for supplying voltage, in particular to a motor vehicle, said device being constructed from a number of energy storage modules (1), said energy storage module (1) being constructed from several prismatic storage cells (10), which are arranged one behind the other so as to be stacked in at least one row (60, 61) and which are clamped between two end plates (30, 35) by means of tension rods (40, 41, 42). The energy storage module according to the invention is characterized in that each row (60, 61) of storage cells is separated from the end plates (30, 35) and the tension rods (40, 41, 42) by an insulating jacket (50, 55) that completely encircles the row (60, 61) of storage cells and that has electrical insulation properties. The electrical insulation properties of the insulating jacket (50, 55) are such that the insulating jacket provides contact protection regarding a voltage obtained by serially connecting all storage cells (10) of the energy storage module and / or regarding a voltage obtained by serially connecting the energy storage modules (1).

Description

technical field [0001] The invention relates to an energy storage module used in a power supply device composed of a plurality of energy storage modules, especially for powering a motor vehicle, wherein the energy storage module is composed of a plurality of prismatic storage batteries stacked into a At least one sequence is arranged one behind the other and is fastened between two end plates by braces. Furthermore, the invention also relates to a method for producing such an energy storage module. Background technique [0002] A plurality of energy storage modules are usually used in the power supply of a motor vehicle, commonly referred to as a battery pack / accumulator, for driving the vehicle, for example an electric vehicle or a hybrid vehicle. Each energy storage module typically consists of a plurality of stacked prismatic storage cells. The individual storage cells contain electrochemical battery cells. In most cases, the stacked single storage batteries are fasten...
