Description

technical field

[0001] The invention relates to a monitoring system for monitoring the state of an energy storage unit storing electrical energy, in particular an electrochemical energy storage unit or an energy storage unit comprising at least one capacitor.

[0002] The invention also relates to a battery system with a plurality of energy storage cells and a central battery control system for controlling and monitoring the energy storage cells. Background technique

[0003] Traditional battery systems are usually subdivided into modules. Each module includes a number of units for its part. The battery system may for example comprise 6 modules with 10 cells each. For example, often in the case of batteries for drive systems of hybrid or electric vehicles in which there is a high demand for energy, battery systems which are subdivided into a plurality of modules are used.

[0004] Each conventional module includes a so-called "cell supervisory circuit" hereinafter referre...
