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 ...
