Method for operating battery cells of a battery, battery and motor vehicle

A method for operating at least two battery cells, which are electrically connected in parallel, of a battery for a motor vehicle, wherein each of the battery cells is provided with a galvanic element provided with two electrodes and a battery housing for accepting the galvanic element with two connections, and each of the electrodes is electrically coupled to a respective connection of the battery cell, comprising:

• each respective value of a state variable of the battery cells is measured, the values of the state variables of the battery cells are compared to one another and when there is a deviation of the mutual values which is outside of a predetermined tolerance range, an electric resistance is adjusted between at least one electrode and one connection of at least one battery cell, so that the deviation is within the predetermined tolerance range.

A battery for a motor vehicle, comprising:

• two battery cells electrically connected in parallel, wherein each of the battery cells is provided with a galvanic element with two electrodes and a battery cell housing for receiving the galvanic element provided with two connections, and each of the electrodes is electrically coupled to the respective connection of the battery cell, wherein each of the battery cells is provided with at least one sensor device, and the battery is provided with a control device which is adapted to compare the values of the state variable of each of the battery cells to one another and if there is a deviation of the values which is outside of a predetermined tolerance range, to adjust an electric resistance between at least one electrode and at least one of the connections of at least one of the battery cells, so that the deviation is within the predetermined tolerance range.
