In an electric drive for a vehicle, a steady-state main operating state, such as drive, recuperation and the like, is important. However, in addition to these primary operating states, a change in the operating state and a secondary operating state and/or an emergency operating state must be taken into account. The aim of the invention is to provide a discharge device for an electric drive, which discharge device is functionally reliable and at the same time can be advantageously designed. The invention relates to a discharge device (8) for an electric drive (1) of a vehicle, comprising: an input interface (9); an output interface (10); a main switching device (11), wherein the main switching device (11) is connected to the input interface (9); a first discharge branch (12a), wherein a first input (13a) of the first discharge branch (12a) is connected to the main switching device (11); the invention relates to a discharge device (8) comprising a first discharge branch (12a), a second discharge branch (12b), and a control device (16), said control device (16) being designed to switch on the first discharge branch (12a) in a first discharge state of the discharge device (8) and to switch on the second discharge branch (12b) in a second discharge state.

    在用于车辆的电驱动器中,稳态的主运行状态,例如驱动、回收等很重要。然而,除了这些主运行状态之外,也必须考虑运行状态的变换以及次运行状态和/或紧急运行状态。本发明基于的目的是,实现一种用于电驱动装置的放电设备,所述放电设备是功能可靠的并且同时可以有益地构造。提出一种用于车辆的电驱动装置(1)的放电设备(8),所述放电设备具有:输入接口(9);输出接口(10);主开关装置(11),其中主开关装置(11)与输入接口(9)连接;第一放电支路(12a),其中第一放电支路(12a)的第一输入端(13a)与主开关装置(11)连接;第二放电支路(12b),并且设有控制装置(16),其中控制装置(16)构成为,在放电设备(8)的第一放电状态下接通第一放电支路(12a)并且在第二放电状态下接通第二放电支路(12b)。
