Abstract

See full text

A test apparatus for testing at least one switch device for a high-voltage battery of a vehicle, includes a voltage source for generating an electrical test voltage between a positive high-voltage path and a negative high-voltage path of the at least one switch device. The test apparatus has a first connecting device and a first current source for feeding a first electrical test current into the positive high-voltage path, wherein the first connecting device, the first current source and the positive high-voltage path together form a first circuit when testing the at least one switch device. The test apparatus has a second connecting device and a second current source for feeding a second electrical test current into the negative high-voltage path, wherein the second connecting device, the second current source and the negative high-voltage path together form a second circuit when testing the at least one switch device.
