Abstract

The invention discloses an electric vehicle controller signal transfer test device, and belongs to the technical field of electric vehicle manufacturing. The test device comprises a transfer wire harness assembly correspondingly connected between a controller of a to-be-tested electric vehicle and an input end of a test box, and a tie-back wire harness assembly is correspondingly connected betweenan output end of the test box and the whole vehicle wire harness of the to-be-tested electric vehicle; multiple testing jacks for testing output signals of the controller are formed in a test panel of the test box, and the testing jacks are respectively connected to detection loops between the input end and the output end of the test box. The test device solves the problems that the transfer modeof output signal testing of an existing controller is difficult to implement and easily causes a certain damage on controller wiring to reduce the insulation property, and there are great limitations.

Description

technical field [0001] The invention relates to the technical field of electric vehicles, in particular to a switching test device for output signals of an electric vehicle controller. Background technique [0002] Electric vehicles are a new energy vehicle that the automotive industry is committed to developing. Electric vehicles provide high-voltage power through power battery packs to drive motors to achieve driving functions; at the same time, electric vehicles also have a 12V low-voltage system to realize low-voltage control systems and controllers. . Electric vehicles contain more controllers than traditional fuel vehicles, and their functions are more complex. In the research and development or production process of electric vehicles, in order to test or debug the controller to the best performance parameters, it is necessary to test various output signals of the controller in real time. The existing output signal tests of the controller include the following two met...
