Embodiment Construction

[0073] The following figures each show an embodiment of a battery system 10 , which can, for example, be a component of an electrically driven vehicle. The features shown in the different figures can form part of the invention individually or in any combination and are not discussed individually. In addition, the same reference numerals denote the same or corresponding components, so that detailed descriptions thereof are not specifically made for each drawing.

[0074] as in figure 1 The battery system 10 shown in a has a battery module 12 with a plurality of battery cells 14 . The battery cells 14 here each have at least one cell unit arranged in a cell housing 16 , wherein the cell housing 16 each has a device for draining the emissions formed in the cell housing 16 in the event of a fault. An exhaust valve 18 for the gas, and an exhaust collector 20 is provided therein for guiding exhaust from the battery system 10 . The exhaust gas collector 20 here comprises openings,...

Abstract

The invention relates to a battery system (10). The battery system has a battery module (12) having a plurality of battery single cells (14), each battery single cell having at least one single cell unit disposed in a single cell housing (16). Each single cell housing (16) has an exhaust valve (18) for exhausting emissions formed in the single-cell housing (16) in case of a failure, and an exhaust collector (20) for exporting the emissions from the battery system (10) is arranged. The exhaust collector has an opening connected with the exhaust valve (18). The invention is characterized in that the exhaust collector (20) can be deformed due to emissions, thereby making the volume enclosed by the exhaust collector increasing. In short, the aforementioned battery system (10) can achieve low cost, space saving, light weight, reliability, and use for exhaust in the case of the faulty battery single cells (14).

Description

technical field [0001] The invention relates to a battery system. The present invention particularly relates to a battery system with an improved venting system for venting battery cells in the event of failure of one or more battery cells. Background technique [0002] Battery systems, for example with lithium-ion batteries, are widespread in many everyday uses. Such battery systems are used, for example, in computers such as notebooks, mobile phones, smartphones, and other applications. Such batteries also offer advantages in the currently widespread electrification of vehicles, such as the electrification of motor vehicles. [0003] For reasons of high-voltage contact protection, to avoid corrosion risks and general contamination risks, because of the venting that takes place, and because of electromagnetic compatibility, the battery system and its subcomponents are often hermetically designed or sealed here. and rigid casing surrounds. The sealing of the housing part...
