The invention relates to a drive system of a battery operated vehicle having a self-guided current rectifier (2), having a battery (6), which is connected electrically parallel to direct voltage connections (P, N) of the self-guided rectifier (2), and having a three-phase machine (16) having two galvanically separated stator winding systems (18, 20), wherein a first stator winding system (18) is connected to alternating voltage connections (R, S, T) of the self-guided rectifier (2). According to the invention, a second stator winding system (20) can be connected by means of a first switch device (SL) to network connection terminals (U, V, W) of the drive system or by means of a second switch device (SF) to alternating voltage connections (R, S, T) of the self-guided rectifier (2). According to the invention, a drive system of a battery-operated vehicle is achieved wherein both galvanically separated stator winding systems (18, 20), coupled in a winding transformer-like manner, of a three-phase machine (16) are used during the "driving" operating state, wherein it is possible for the two stator winding systems 18 and 20 to actively influence the current distribution. |
