Abstract
The invention relates to a battery system (), in particular for an electrically driven motor vehicle, having at least one battery sub-unit () and at least one high-power line (), wherein the battery sub-unit () has at least one galvanic element (), at least one power switching transistor (), which is connected in series with the galvanic element () and via which the galvanic element () can be electrically conductively connected to the high-power line (), at least one power bypass transistor (), which is connected in parallel with the power switching transistor () and the galvanic element (), and at least one electronic device (), which is configured to acquire at least one operating parameter of the battery sub-unit () and has a communication link with the power switching transistor () and/or the power bypass transistor (), wherein the electronic device () is configured to generate a data signal assigned to the operating parameter, in that the electronic device () activates the power switching transistor () and/or the power bypass transistor () electrically in such a way that the electrical resistance of the power switching transistor () and/or of the power bypass transistor () is modulated in at least one predefinable time interval, in order to modulate the level of the electric current flowing in the high-power line ().
