CPC G01R 31/3272 (2013.01) [G01R 31/3336 (2013.01)] | 11 Claims |
1. A test apparatus for simultaneously testing at least two switch devices for a high-voltage battery of a vehicle, comprising:
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 two switch devices;
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 two switch devices, and
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 two switch devices, wherein
the at least two switch devices are electrically connected in series, such that respective positive high-voltage paths of the at least two switch devices are part of the first circuit and respective negative high-voltage paths of the at least two switch devices are part of the second circuit,
the first current source is configured to feed the first electrical test current into the respective positive high-voltage paths of the at least two switch devices, and
the second current source is configured to feed the second electrical test current into the respective negative high-voltage paths of the at least two switch devices.
