摘要：
Electric drive device (1) for a vehicle (100), comprising:
- an electric machine (2);
- a housing (3) having a DC power interface (4) connectable with a highvoltage battery (101) of the vehicle (100) disposed outside the housing (3);
- DC power lines (5) configured to carry a DC voltage provided at the DC power interface (4);
- a DC link capacitor (6) connected between the DC power lines (5);
- an inverter (7) having an AC output (8) connected to the electric machine (2) and a DC input (9) connected to the DC power lines (5); and
- an electric auxiliary device (10) electrically suppliable via the DC power lines (5) and configured to dissipate electric energy stored in the DC link capacitor (6) and/or in the electric machine (2) in an operation state, where the highvoltage battery (101) is disconnected from the DC power interface (4);
wherein the DC power lines (5), the DC link capacitor (6) and the auxiliary device (10) are arranged inside the housing (3).
