Embodiment Construction

[0034] exist figure 1 The schematic basic structure of the battery system 10 according to the invention is shown as an example in , but is not limited thereto. According to the invention, battery system 10 has at least two storage units 14 . The storage units 14 are preferably arranged such that a plurality of storage units 14 each form a battery module 12 . According to the invention, battery system 10 can have a plurality of such battery modules 12 .

[0035] exist figure 1 In the example, the battery module 12 has six interconnected storage units 14 . According to the invention, battery module 12 can also have more than six storage cells 14 or less than six storage cells 14 . The number of storage units 14 depends on the required power and energy parameters of the battery module 12 and on the power and energy parameters of the individual storage units 14. The number of battery modules 12 in battery system 10 is correspondingly dependent on the required performance and ...

Abstract

A battery system (10) is described having at least two storage units (14) and an exhaust system (40) connected in fluid communication with the storage units (14), the battery system (10) comprising at least one arrangement A signal generator (20) in the exhaust system (40) and an evaluation unit (30) for evaluating the signal of the at least one signal generator (20). The at least one signal generator (20) is configured in such a way that when there is a predetermined volume flow at the signal generator or with a predetermined pressure difference consequently occurring therefrom before and after the signal generator (20), the changeover its signal state. Furthermore, a motor vehicle with the battery system (10) and a method for determining the degassing of a storage unit (14) of the battery system (10) are proposed.

Description

technical field [0001] The invention relates to a battery system having at least two storage units and a venting system, a motor vehicle with such a battery system, and a method for determining the venting of a storage unit of a battery system. Background technique [0002] Battery systems are known which are constructed from a plurality of subunits. The individual subunits are here formed at least by individual memory cells. A single subunit can also have a plurality of storage units combined to form a battery module or a plurality of such battery modules. The battery system is thus formed from at least two storage units connected to one another. [0003] Storage cells, such as lithium-ion battery cells, require venting openings, since certain operating states can lead to an overvoltage of the battery cells. Gas under pressure must be able to escape. For this purpose, so-called exhaust systems are known in battery systems, which receive and discharge the gases formed by...
