Embodiment Construction

[0027] Respectively figure 1 and figure 2 The battery system 1 shown in is designed for use in a hybrid, plug-in hybrid or electric vehicle. The battery system 1 here includes a plurality of battery cells 2 and a battery management system 8 . The battery cells 2 are here preferably rechargeable lithium-ion cells. The battery cells 2 are electrically connected to one another in series to form battery modules 3 , wherein the battery modules 3 are in turn electrically connected to one another.

[0028] The battery system 1 has two connection contacts 4 for connecting electrical consumers and / or charging devices for charging the battery cells 2 of the battery system 1 . In this case, each switching element 6 configured as a relay is connected upstream of the corresponding connection contact 4 . In this case, the switching element 6 of the battery system 1 is controlled by means of the control circuit 5 and is controlled such that the switching element 6 is closed when the con...

Abstract

Provided are a battery system and a method of isolating a battery system an electric consumer connected to the battery system. The invention relates to the battery system, which has at least one battery and at least one connecting contact portion used for being connected to an electric consumer. At least one switch element controlled by means of a control circuit is connected prior to the at least one connecting contact portion, is turned on in a condition of a closed control circuit, and is turned off in a condition of an interrupted control circuit. The control circuit includes at least one hot melting fuse, which interrupts the control circuit when being triggered. The at least one hot melting fuse is distributed to the at least one battery. In addition, the invention relates to a method of isolating the battery system having at least one battery from the electric consumer that is connected to the battery system through the at least one connecting contact portion.

Description

technical field [0001] The invention relates to a battery system having at least one battery cell and at least one connection contact for connecting an electrical consumer, wherein at least one controllable battery cell is connected upstream of the at least one connection contact A switching element, wherein the at least one switching element is closed in the case of a closed control circuit and opened in the case of an interrupted control circuit. [0002] In addition, the invention relates to a method for connecting a battery system having at least one battery cell to a terminal via the at least one connecting contact by means of at least one switching element connected upstream of at least one connecting contact. Method for galvanic isolation of consumers on a battery system, the switching element being controlled by means of a control circuit in such a way that the at least one switching element is closed in the case of a closed control circuit and closed in the case of an...
