Abstract
The invention relates to a method for the voltage-controlled deactivation of battery cells (22) within a battery module (34, 38) or a battery pack (48) and for the voltage-controlled deactivation of electronic components (40, 52.1-52.8, 54) which are electrically connected to the battery cells and which are supplied with power by the battery cells. If a voltage falls below a threshold in the battery cells (22), supply lines (44, 46, 68, 70) to the electronic components (40, 52.1-52.8, 54) are automatically interrupted and/or battery cells (22) of the battery modules (34, 38) are separated from the main current circuit of the battery or of a battery pack (48).
