Abstract
A method for regulating a battery voltage of a battery having a plurality of battery cells configured to be selectively bridged and connected to a battery string includes regulating the battery voltage to a desired nominal voltage by alternately driving the battery cells. The method further includes transmitting a value for a nominal switch-on probability to one or more driving circuits of the battery cells, with the result that the one or more battery cells are each switched with an allocated switch-on probability.

A method for regulating a battery voltage of a battery including a plurality of battery cells, the battery cells of the plurality of battery cells (i) configured to be selectively bridged and connected to a battery string, and (ii) including a respective driving circuit, the method comprising:
- regulating the battery voltage to a desired nominal voltage by alternately driving the battery cells of the plurality of battery cells;
- and
- transmitting a nominal switch-on probability to one or more of the respective driving circuits of the battery cells of the plurality of battery cells, such that one or more of the battery cells of the plurality of battery cells are each switched with an allocated switch-on probability.
A battery comprising:
- at least one battery string including a plurality of battery cells configured to be bridged and connected to the battery string by a respective driving circuit;
- a recording device configured to record operating parameters of the battery cells of the plurality of battery cells;
- and
- regulating electronics configured (i) to regulate a battery voltage, and (ii) to use a central drive signal to transmit a nominal switch-on probability to the driving circuits of each battery cell of the plurality of battery cells,
- wherein the driving circuits are configured to switch a respective battery cell of the plurality of battery cells with a switch-on probability allocated to the respective battery cell on the basis of the nominal switch-on probability.
A motor vehicle comprising:
- an electric motor;
- and
- a battery configured to supply the electric motor with electrical energy, the battery including (i) at least one battery string including a plurality of battery cells configured to be bridged and connected to the battery string by a respective driving circuit, (ii) a recording device configured to record operating parameters of the battery cells of the plurality of battery cells, and (iii) regulating electronics configured to regulate a battery voltage, and to use a central drive signal to transmit a nominal switch-on probability to the driving circuits of each battery cell of the plurality of battery cells,
- wherein the driving circuits are configured to switch a respective battery cell of the plurality of battery cells with a switch-on probability allocated to the respective battery cell on the basis of the nominal switch-on probability.
