Abstract (en)

[origin: WO2012032428A1] A method for monitoring a rechargeable battery (1 ) with multiple cells (2, 2a..2n) is described, as well as a cell monitoring unit (3, 3a..3n) for such, in which in a normal mode (MN) a measurement (UCa, UCb) of a parameter of a cell (2, 2a..2n) is determined using a reference value (URa, URb) provided for each cell (2, 2a..2n). In addition, in a test mode (MT) the reference values (URa, URb) of adjacent cells (URb) used for determining measurements (UCa, UCb) of the parameter in question and provided for each cell (2, 2a..2n) are compared with each other in a periodically recurring manner. An error signal is issued if the comparison result exceeds a predefinable limit value.
