Embodiment Construction

[0040] In the following figures, the same reference signs are also used for the same technical features of the different exemplary embodiments.

[0041] exist Figures 1 to 6 A monitoring arrangement 10 according to the invention for a battery system 2 of a vehicle 1 is shown in . It can be seen here that at least one electronic processing unit 20 is provided, which is (correspondingly) assigned to exactly one battery cell 3 of the battery system 2 . For example, the processing device 20 can be attached directly to the battery unit 3 . In addition, two parallel electrical connection means 30 at the (respective) processing means 20 can provide electrical contacts by means of which the processing means 20 are redundantly electrically connected to the (same) potential of the battery cells 3 . Two connection means 30 can have the same function in parallel and provide the electrical connection in the same way (with equal potential), so that there is corresponding redundancy. Exe...

Abstract

The invention relates to a monitoring assembly (10) for a battery system (2) of a vehicle (1), comprising: at least one electronic processing means (20), each associated with exactly one battery cell(3) of the battery system (2); and two electrical connection means (30) on the processing means (20) in order to electrically connect the processing means (20) redundantly to the potential of the battery cell (3).

Description

technical field [0001] The invention relates to a monitoring arrangement for a battery system of a vehicle. Furthermore, the invention relates to a battery system. Background technique [0002] It is known from the prior art to generally use a battery system as an electrical energy store in vehicles with an electric drive train. The battery management system (BMS) of the battery system is usually used for monitoring, regulation and for protecting the energy storage. The battery system can additionally have a plurality of battery cell strings, in which in turn a plurality of battery cells are connected. [0003] In addition, requirements for the safety of the respective battery cells can be accommodated by measuring the battery cell voltage and monitoring compliance with limits (in particular overcharge and deep discharge protection). According to conventional solutions, a measurement line for each cell potential (that is to say each potential of the cell) can be led to a ...
