Battery with Variable Output Voltage

A motor vehicle comprising:

• an electric drive motor configured to propel the motor vehicle;
• and
• a battery which is connected to the electric drive motor,
• wherein the battery includes (i) at least one battery module line having a plurality of series-connected battery modules, and (ii) a control unit,
• wherein each battery module of the plurality of series-connected battery modules includes (i) at least one battery cell and (ii) a coupling unit,
• wherein the at least one battery cell is connected between a first input and a second input of the coupling unit,
• wherein the coupling unit is configured (i) to switch the at least one battery cell between a first terminal of the battery module and a second terminal of the battery module in response to a first control signal, and (ii) to connect the first terminal to the second terminal in response to a second control signal, and
• wherein the control unit is configured (i) to transmit the first control signal to a first variable number of battery modules of the plurality of series-connected battery modules and (ii) to transmit the second control signal to a remaining number of the battery modules of the plurality of series-connected battery modules, thereby enabling variable regulation of an output voltage of the at least one battery module line.
