Problems solved by technology

Since the electrolyte used in memory cells is usually conductive, this can lead to short circuits within the memory module and the functionality of the entire memory module can no longer be guaranteed
[0006] The devices described in the prior art are not suitable for confining large volumes of temperature control medium which, in case of damage, escape from a temperature control system which closes the interior of the battery housing, and are thus not suitable for effectively preventing Damage to battery systems and units

Embodiment Construction

[0028] exist figure 1 In the exemplary embodiment shown in , the battery system includes a plurality of battery elements 13 each having battery electrodes 14 , 15 . The battery monitoring unit 17 is arranged on a separator element 18 in the region of the battery electrodes 14 , 15 in a manner spanning a plurality of battery cells. The battery monitoring unit may have means for monitoring the battery voltage and / or the temperature of individual battery cells (eg, voltage spur elements and / or temperature sensors not shown in the schematic drawings). The battery cells are connected to each other through battery connectors (not shown). The temperature control module 20 has an inlet opening 21 and an outlet opening 22 and through the inlet opening 21 and the outlet opening 22 a liquid temperature control medium flows through which the temperature of the liquid temperature control medium is controlled by an external device. The battery system is arranged on the temperature control...

Abstract

The invention discloses a battery system comprising a battery cell (13), at least one absorbing element (30, 35) and a liquid-temperature Temperature control system for the control medium, the absorber element (30, 35) for containing the liquid temperature control medium is arranged between the battery cell (13) and the battery housing (10), the absorber element (30, 35) is a non-woven fabric , the non-woven fabric has an average area-related mass from 250 to 700 g / m2 and comprises fibers of at least two different fiber types, at least one of which is a supporting fiber, at least one other of which is One is absorbent fibers. The invention also discloses a motor vehicle including a battery system.

Description

technical field [0001] The invention relates to a battery system comprising at least one battery cell, an absorbing element, and a temperature control system with a liquid temperature control medium for cooling and / or heating of the battery cells inside a battery housing, and to a motorized battery system comprising the battery system vehicle. Background technique [0002] Battery systems with a plurality of battery cells are used in particular as energy storage for electric and hybrid vehicles. In order to guarantee optimal energy storage function, it is necessary to keep the temperature of the battery cells within the required operating range. To prevent overshooting and / or undershooting of the operating temperature, active or passive temperature control systems are used. The use of a high heat capacity liquid temperature control medium has proven itself in particular in heat exchangers, where this temperature control medium is guided along the battery cells in a satisfa...
