Abstract

A vehicle having an energy storage element including a drive inverter and a charging unit. The energy storage element further includes a first control apparatus, modules, an interconnection apparatus, and two first poles, the drive inverter is connected to said two first poles. Each modules of said modules has an energy storage unit. The interconnection apparatus has connections between the modules and first switches provided on the connections in order to allow different interconnections of the modules and different voltages at the first poles based on a state at the first switches. Different interconnections of the modules allow at least two interconnections from the group of interconnections. The first control apparatus is configured to actuate the interconnection apparatus based on a voltage setpoint value in order to influence the different voltages at the two first poles based on the voltage setpoint value.
